This prospectus supplement is being furnished to you as a stockholder of Ampio Pharmaceuticals, Inc., or Ampio. Ampio owns 11,626,068 shares of our common stock, $0.0001 par value per share, which represents approximately 81.5% of our outstanding shares of common stock as of October 31, 2015. Ampio plans to distribute approximately 72.9% of our common stock to its stockholders.

To effect the spin-off, Ampio will make a pro rata distribution of approximately 10,399,661 shares of Aytu common stock to holders of Ampio common stock as of 5:00 p.m., New York City time, on December 1, 2015, the record date for the spin-off. Ampio will distribute one share of Aytu common stock for every five shares of Ampio common stock held by an Ampio stockholder. The distribution date for the spin-off will be on or about January 4, 2016.

As discussed under “The Spin-off-Trading of Ampio Common Stock Prior to or on the Distribution Date,” if you sell your shares of Ampio common stock before or on the distribution date, January 4, 2016, you will be selling the shares of Aytu common stock you will receive in connection with the spin-off, and will have to deliver those shares when you receive them. You are encouraged to consult with your financial advisor or broker regarding the specific implications of selling your Ampio common stock before or on the distribution date.

You will not be required to pay any cash or other consideration for the shares of Aytu common stock that will be distributed to you or to surrender or exchange your shares of Ampio common stock to receive Aytu common stock in the spin-off. The distribution will not affect the number of shares of Ampio common stock that you hold. No approval by Ampio stockholders of the spin-off is required or being sought. You are not being asked for a proxy and you are requested not to send a proxy.

Our common stock is listed on the OTCQB Market operated by OTC Markets Group, Inc., or OTCQB, under the ticker symbol “AYTU.” On November 30, 2015, the last reported bid price of our common stock on the OTCQB was $3.30 per share. Between January 1, 2015 and November 17, 2015 (the day on which the terms of the spin-off were announced), there were reported trades of Aytu shares on only 24 days, involving a total of only 22,720 shares.

Ownership of our common stock involves a high degree of risk. You should carefully consider all of the information set forth in this prospectus supplement and the Accompanying Prospectus (as defined under “About this Prospectus Supplement”). See “Risk Factors” beginning on page S-6 of this prospectus supplement, page 10 of the accompanying prospectus dated October 23, 2015 and page 28 of the accompanying prospectus supplement No. 1 dated November 10, 2015.

Any representation to the contrary is a criminal offense.

This prospectus supplement does not constitute an offer to sell or the solicitation of an offer to buy any securities.

This document is in three parts. The first part is this prospectus supplement, which describes the distribution by Ampio. The second part, the accompanying prospectus dated October 23, 2015 (the “October Prospectus”), provides information about us, about our common stock, and about possible sales of our common stock. The third part, the accompanying prospectus supplement No. 1 dated November 10, 2015 (“Supplement No. 1”), provides the information contained in our Quarterly Report on Form 10-Q, which was filed with the SEC on November 6, 2015. We refer to the October Prospectus and Supplement No. 1 together as the “Accompanying Prospectus.” Generally, when we refer to this prospectus, we are referring to all three parts of this document combined. You should carefully read this prospectus supplement and the Accompanying Prospectus, as well as the additional information described under “Where You Can Find Additional Information” on page S-15 of this prospectus supplement.

To the extent that any statement that we make in this prospectus supplement is inconsistent with statements made in the Accompanying Prospectus, the statements made in this prospectus supplement will be deemed to modify or supersede those made in the Accompanying Prospectus.

Ampio is listed as a selling stockholder in the October Prospectus (see “Selling Stockholders” in the October Prospectus). Rather than sell its shares of Aytu common stock, Ampio will distribute approximately 10,399,661 of its Aytu shares to its stockholders on a pro rata basis as described in this prospectus supplement.

This prospectus supplement is being furnished solely to provide information to Ampio stockholders who will receive shares of Aytu common stock in the spin-off. It is not and is not to be construed as an inducement or encouragement to buy or sell any securities of Ampio or Aytu. This prospectus supplement describes, among other things, Aytu’s relationship with Ampio and how the spin-off affects Ampio and its stockholders, and provides other information to assist you in evaluating the benefits and risks of holding or disposing of the shares of our common stock that you will receive in the spin-off. You should rely only on the information contained in this prospectus supplement, the Accompanying Prospectus and in any other prospectus supplements we may provide to you in connection with this distribution. We have not authorized any other person to provide any information other than that contained in this prospectus supplement and in the Accompanying Prospectus or in any other prospectus supplement prepared by us. We do not take any responsibility for, and can provide no assurance as to the reliability of, any information that others may give you. Persons outside the United States who come into possession of this prospectus supplement and the Accompanying Prospectus must inform themselves about, and observe any restrictions relating to, the distribution of the common stock and the distribution of this prospectus supplement and the Accompanying Prospectus outside the United States. You should not assume that the information contained in this prospectus supplement or the Accompanying Prospectus is accurate as of any dates other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates.

Summary of the Spin-off

The following is a brief summary of the terms of the spin-off. Please see “The Spin-off” for a more detailed description of the matters described below.


Distributing company		Ampio, which is the parent company of Aytu. After the distribution, Ampio will retain approximately 1,226,407 shares of our common stock.

Distributed company		Aytu, which is currently an 81.5% owned subsidiary of Ampio.

Shares to be distributed		Approximately 10,399,661 shares of Aytu common stock, which is approximately 89.5% of the shares currently owned by Ampio. Our common stock to be distributed will constitute approximately 72.9% of our outstanding common stock immediately after the spin-off.

Distribution ratio		Each holder of Ampio common stock will receive one share of Aytu common stock for every five shares of Ampio common stock held on the record date.

Fractional shares		The transfer agent identified below will round fractional shares equal to or greater than one half up into a whole share and less than one half down into a whole share. The transfer agent is not an affiliate of Ampio or us. See “The Spin-off - Treatment of Fractional Shares.”

Distribution procedures and trading		On or about the distribution date, the distribution agent identified below will distribute our common stock by crediting those shares to book-entry accounts established by the transfer agent for persons who were stockholders of Ampio as of 5:00 p.m., New York City time, on the record date. You will not be required to make any payment or surrender or exchange your Ampio common stock or take any other action to receive our common stock. However, as discussed below, if you sell Ampio common stock before or on the distribution date, you will be selling the associated shares of Aytu common stock you will receive in the distribution. Registered stockholders will receive additional information from the transfer agent shortly after the distribution date. Beneficial stockholders will receive information from their brokerage firms.


Distribution agent, transfer agent and registrar for our common stock		Corporate Stock Transfer, which currently serves as the transfer agent and registrar for Ampio’s common stock.

Record date		5:00 p.m., New York City time, on December 1, 2015.

Distribution date		On or about January 4, 2016

Trading before or on the distribution date		Any holder of Ampio common stock who sells Ampio common stock before or on the distribution date will be selling the Aytu common stock the holder will receive in the spin-off and a due bill evidencing the obligation to deliver those shares when they are received will automatically be attached by the NYSE MKT. You are encouraged to consult with your financial advisor or broker regarding the specific implications of selling Ampio common stock before or on the distribution date.

U.S. federal income tax considerations		The distribution of Aytu common stock to the Ampio stockholders will generally be treated as a taxable transaction to the Ampio stockholders and also to Ampio for U.S. federal income tax purposes under the Internal Revenue Code of 1986, as amended, or the Code. However, because Ampio expects that it will not have current or accumulated earnings and profits for U.S. federal income tax purposes for the taxable period that includes the distribution, it does not expect that the distribution will be treated as a dividend for such purposes. This treatment will depend in part on the value of Aytu common stock as determined for purposes of the distribution and there can be no assurance that no portion of the distribution will be treated as a dividend. Because of the complexities of the tax laws, we advise you to consult your personal tax advisors concerning the applicable U.S. federal, state, local and foreign income and other tax consequences of the distribution. Certain U.S. federal income tax considerations related to the distribution and to holding Aytu common stock are described in more detail under “Certain material U.S. Federal Income Tax Considerations of the Distribution.”

Reasons for the spin-off		Ampio’s board of directors and management believe that the distribution will provide the following benefits: (i) providing both companies greater flexibility to focus on their distinct growth and development strategies within their respective core markets, enabling them to further improve competitiveness and create value for shareholders, customers and employees; (ii) enabling each company to better allocate resources to meet the needs of their respective businesses, pursue distinct capital allocation strategies, intensify focus on growth and development priorities, and provide a clearer investment thesis to attract a long-term investor base best-suited to each company; (iii) providing the ability to better align incentive compensation with the financial performance of each business, as well as the ability to attract and retain key employees; (iv) removing competition for capital between the companies, allowing each to establish an appropriate capital structure to allow increased access to the capital markets to fund its growth strategy; and (v) increasing the flexibility to independently evaluate and finance organic and inorganic growth opportunities without limitations of operating as a consolidated entity. For more information, see “The Spin-off - Reasons for the Spin-off.”

QUESTIONS AND ANSWERS ABOUT THE SPIN-OFF

Q:	What is the spin-off?

In the spin-off, Ampio will distribute to its stockholders approximately 10,399,661 of the shares of our common stock that it owns, which is approximately 89.5% of the shares Ampio currently owns. You do not have to pay any consideration or give up any portion of your Ampio common stock to receive our common stock in the spin-off.

Q:	What is the expected date for the completion of the spin-off?

A:	The completion and timing of the spin-off are dependent on a number of conditions, but if such conditions are timely met, we expect the spin-off to be completed on or about January 4, 2016. See “The Spin-off - Spin-off Conditions and Termination”.

Q:	What are the reasons for and benefits of the distribution?

Ampio’s board of directors and management believe that the distribution of Aytu stock will provide the following benefits: (i) providing both companies greater flexibility to focus on their distinct growth and development strategies within their respective core markets, enabling them to further improve competitiveness and create value for shareholders, customers and employees; (ii) enabling each company to better allocate resources to meet the needs of their respective businesses, pursue distinct capital allocation strategies, intensify focus on growth and development priorities, and provide a clearer investment thesis to attract a long-term investor base best-suited to each company; (iii) providing the ability to better align incentive compensation with the financial performance of each business, as well as the ability to attract and retain key employees; (iv) removing competition for capital between the companies, allowing each to establish an appropriate capital structure to allow increased access to the capital markets to fund its growth strategy; and (v) increasing the flexibility to independently evaluate and finance organic and inorganic growth opportunities without limitations of operating as a consolidated entity. See “The Spin-off - Reasons for the Spin-off.”

Q:	Who will manage Aytu after the distribution?

A:	We will continue to be led by Joshua R. Disbrow, our Chief Executive Officer, who will oversee the rest of our experienced management team, including Jarrett T. Disbrow, our Chief Operating Officer, Gregory A. Gould, our Chief Financial Officer, and Jonathan McGrael, our Vice President of Sales.

Q:	What is being distributed in the spin-off?

A:	Ampio will distribute one share of our common stock for every five shares of Ampio common stock outstanding as of the record date for the spin-off. The number of shares of Ampio you own and your proportionate interest in Ampio will not change as a result of the spin-off.

Q:	What is the record date for the spin-off, and when will the spin-off occur?

A:	The record date is December 1, 2015, and ownership is determined as of 5:00 p.m., New York City time, on that date. Our common stock will be distributed on or about January 4, 2016, which we refer to as the distribution date.

Q:	Can Ampio decide to cancel the spin-off even if all the conditions have been met?

Yes. Ampio has the right not to complete the spin-off if, at any time prior to the record date, the board of directors of Ampio determines, in its sole discretion, that the spin-off is not in the best interests of Ampio or its stockholders, that a sale or other alternative is in the best interests of Ampio or its stockholders, or that market conditions or other circumstances are such that it is not advisable to distribute Aytu stock. In the event the Ampio board of directors abandons the spin-off, Ampio will notify its stockholders in a manner reasonably calculated to inform them of such abandonment with a press release, a Current Report on Form 8-K or other similar means.

Q:	As a holder of Ampio common stock as of the record date, what do I have to do to participate in the spin-off?

You are not required to take any action to participate in the spin-off, although you are urged to read this entire document carefully. You will receive one share of Aytu common stock for every five shares of Ampio common stock held as of the record date. You may also participate in the spin-off if you purchase Ampio common stock after the record date and before or on the distribution date, and retain your Ampio common stock through the distribution date. See “The Spin-off - Trading of Ampio Common Stock Prior to or on the Distribution Date.”

Q:	If I sell my Ampio common stock before or on the distribution date, will I still be entitled to receive Aytu common stock in the spin-off?

If you sell your Ampio common stock before or on the distribution date, you will also be selling your right to receive shares of our common stock in the spin-off. See “The Spin-off - Trading of Ampio Common Stock Prior to or on the Distribution Date.” You are encouraged to consult with your financial advisor or broker regarding the specific implications of selling your Ampio common stock before or on the distribution date.

Q:	How will fractional shares be treated in the spin-off?

A:	Any fractional common shares equal to or greater than one half will be rounded up into whole shares and any fractional common shares less than one half will be rounded down into whole shares.

Q:	Will my Ampio common stock continue to trade on a stock market?

A:	Yes, Ampio common stock will continue to be listed on the NYSE MKT under the symbol “AMPE.”

Q:	Will the distribution be taxable to me under U.S. federal income tax law?

A:	The distribution will be a taxable transaction. However, because Ampio expects that it will not have current or accumulated earnings and profits for U.S. federal income tax purposes for the taxable period that includes the distribution,

it does not expect the distribution will be treated as a dividend for such purposes. In this case, the distribution would generally be treated as a return of capital and then as capital gains to the Ampio stockholders. Nevertheless, as the determination of Ampio’s current and accumulated earnings and profits will be affected by the value of Atyu common stock as determined for purposes of the distribution, there can be no assurance that no portion of the distribution will be treated as a dividend. For a more detailed explanation of the tax considerations in connection with the distribution of Aytu common stock see “Certain Material U.S. Federal Income Tax Considerations of the Distribution” beginning on page S-10. The tax consequences may vary depending upon the particular circumstances of each stockholder. You should consult your tax advisor with respect to the tax consequences of the distribution of Aytu common stock to you, including under any applicable U.S. federal, state, local and foreign income and other tax laws.

Q:	What if I hold my Ampio common stock through a broker, bank or other nominee?

A:	Ampio stockholders who hold their shares of Ampio common stock through a broker, bank or other nominee will have their brokerage account credited with Aytu common stock. For additional information, those stockholders should contact their broker or bank directly.

Q:	Are there risks to owning shares of our common stock?

A:	Yes. Our business is subject both to general and specific business risks relating to our operations. In addition, the spin-off presents risks relating to us being an independent company. See “Risk Factors.”

Q:	Will Aytu common stock continue to trade on a stock market?

A:	Yes, Aytu common stock will continue to be quoted on the OTCQB under the symbol “AYTU.”

Q:	What will the relationship between Ampio and Aytu be following the spin-off?

Ampio and Aytu are currently party to several agreements pursuant to which Ampio provides corporate overhead services, a shared facility, corporate staff and other miscellaneous overhead expenses in exchange for a monthly cash payment from us. By their terms, these agreements remain in effect until they are terminated in writing by both parties and we expect these agreements to remain in effect following the distribution.

Q:	Will I have appraisal rights in connection with the spin-off?

A:	No. Holders of Ampio common stock are not entitled to appraisal rights in connection with the spin-off.

Q:	Who is the transfer agent for your common stock?

A:	Corporate Stock Transfer.

Q:	Who is the distribution agent for the spin-off?

A:	Corporate Stock Transfer.

Q:	Whom can I contact for more information?

The following are certain risk factors that relate to the spin-off of our common shares by Ampio and that could affect our business, financial condition and results of operations. The Accompanying Prospectus describes risk factors relating to us and our business that are not related to the spin-off. You should carefully consider the risks described in this prospectus supplement and the Accompanying Prospectus. The risks described below and in the Accompanying Prospectus are not the only ones we face. If any of the following risks or the risks described in the Accompanying Prospectus materializes, our business, financial condition or results of operations could be adversely affected. Also, this prospectus supplement and the Accompanying Prospectus contain forward looking statements about expected future occurrences or conditions. Our actual results could differ materially from those anticipated in the forward-looking statements made throughout this prospectus supplement and the Accompanying Prospectus as a result of different factors, including the risks we face described below and in the Accompanying Prospectus. See also “Risk Factors” beginning on page 10 of the October Prospectus and beginning on page 28 of Supplement No. 1.

The distribution of Aytu common stock to the Ampio stockholders will generally be treated as a taxable transaction to the Ampio stockholders and also to Ampio for U.S. federal income tax purposes under the Code. However, because Ampio expects that it will not have current or accumulated earnings and profits for U.S. federal income tax purposes for the taxable period that includes the distribution, it does not expect the distribution will be treated as a dividend for such purposes. Nevertheless, as this treatment will depend in part on the value of Aytu common stock as determined for purposes of the distribution, there can be no assurances that no portion of the distribution will be treated as a dividend. Because of the complexities of the tax laws, we advise you to consult your personal tax advisors concerning the applicable U.S. federal, state, local and foreign income and other tax consequences of the distribution. Certain U.S. federal income tax consequences of the spin-off are described in more detail under “Certain Material U.S. Federal Income Tax Consequences of the Distribution.”

Future sales of Aytu common stock could adversely affect its stock price and its ability to raise capital in the future.

An estimated 10,399,661 shares of Aytu common stock will be transferred to Ampio stockholders in the spin-off. The shares to be issued in the spin-off will be freely tradable without restriction under the Securities Act of 1933, or the Securities Act, by persons other than “affiliates” (as defined under the Securities Act) of Aytu. Sales of substantial amounts of Aytu common stock by the Ampio stockholders who receive the shares in the spin-off could adversely affect the market price of Aytu stock, as could the perception that those sales might occur.

Members of our board of directors and management may have actual or potential conflicts of interest because of their ownership of Ampio common stock or their current or prior relationships with us and/or Ampio.

After the spin-off, we will be managed by our sole current director and four current executive officers. Our sole director and our Chief Financial Officer also serve in those capacities at Ampio. In addition, at the time of the distribution, it is expected that the sole member of our board of directors and two of our three executive officers will own Ampio common stock and/or equity awards for Ampio common stock because of their current or prior relationships with Ampio, which could create, or appear to create, potential conflicts of interest when our directors and executive officers are faced with decisions that could have different implications for us and Ampio. These facts may create, or appear to create, potential conflicts of interest if this director and these executive officers are faced with decisions that could have different implications for Ampio than the decisions have for us.

We may not realize the potential benefits that we expect from our spin-off from Ampio. We have described those anticipated benefits elsewhere in this prospectus supplement. See “The Spin-off - Reasons for the Spin-off.”

Ampio’s board of directors may abandon the spin-off at any time before the record date.

No assurance can be given that the spin-off will occur or, if it occurs, that it will occur on the terms described in this prospectus supplement. Ampio’s board of directors may abandon the spin-off at any time before the record date for any reason or for no reason. In addition, Ampio’s board of directors may amend or modify any and all of the terms of the spin-off at any time prior to the record date. If any material amendments or modifications are made to the terms of the spin-off before the record date, Ampio will notify its stockholders in a manner reasonably calculated to inform them of such modifications with a press release, Current Report on Form 8-K or other similar means.

To date, Ampio has provided most of the funds we have had available for our activities. It did this by (1) lending $4,000,000 to Vyrix Pharmaceuticals, Inc. and $8,000,000 to Luoxis Diagnostics, Inc., and then forgiving those loans in exchange for 2,164,448 shares of Aytu common stock when we acquired Vyrix and Luoxis from Ampio through mergers in April 2015, and (2) at the same time as the mergers, purchasing 2,597,339 shares of our common stock for $10 million, of which it paid $5 million in June 2015 and expects to pay the remaining $5 million in December 2015. The only significant funding we have received from anybody other than Ampio is the proceeds of sales in July and August 2015 of an aggregate of $5.2 million of convertible notes that will mature in January and February 2017, but which we will be able to satisfy with shares of our common stock, rather than cash. At September 30, 2015, we had $10.2 million in cash and accounts receivable and $1.7 million in accounts payable and accrued liabilities, and we had the commitment from Ampio to pay the $5 million balance of the purchase price of the 2,597,339 shares of our common stock it purchased in April 2015. We believe that will be sufficient to meet our cash needs through 2016, and possibly into early 2017. We do not expect that Ampio will provide any additional funding to us. Therefore, unless we begin to have significant revenues or can arrange third party financing by the end of 2016, we could run out of money by early 2017.

There is no active trading market for our common stock, and there is no reliable market price for our common stock.

Although our common stock is quoted on the OTCQB Market operated by OTC Markets Group, Inc., there were reported trades in our common stock on only 24 days between January 1, 2015, and November 17, 2015 (the day on which the terms of the spin-off were announced), and those trades related to a total of only 22,720 shares. Because of this very small volume of trading, the currently quoted prices of our common stock probably do not represent a real market price. In April 2015, we sold 4,761,787 shares of common stock to Ampio for $4.62 per share, but that was in connection with the mergers by which we acquired the companies that now conduct our entire business, and the price was set primarily by Ampio rather than through arm’s length bargaining. Further, in the preparation of our financial statements for the quarter ended September 30, 2015, to value the warrant derivative liability for certain warrants, we used the Monte Carlo valuation methodology, under which we estimated the value of our common stock was between $1.51 and $1.95 per share. Therefore, there is no basis for determining (a) whether there will be a trading market for our common stock after the spin-off, or (b) if there is a trading market, the price at which our common stock is likely to trade.

On November 2, 2015, the day on which Ampio announced its intention to spin off at least most of its holding of our common stock, the closing price of Ampio’s common stock fell by approximately 5% from $3.75 to $3.56. It is possible that the prospect of the spin-off and the spin-off itself will result in a further decline in the market price of Ampio’s common stock.

This prospectus supplement and the Accompanying Prospectus contain forward-looking statements that are based on our management’s belief and assumptions and on information currently available to our management. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. These statements relate to our future plans, objectives, expectations, intentions and financial performance and the assumptions that underlie these statements. Forward-looking statements in this prospectus supplement and the Accompanying Prospectus include, but are not limited to, statements about:

In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue” or the negative of these terms or other comparable terminology. These statements are only predictions. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, which are, in some cases, beyond our control and which could materially affect results. Factors that may cause actual results to differ materially from current expectations include, among other things, those listed under “Risk Factors” and elsewhere in this prospectus supplement, the October Prospectus and Supplement No. 1. If one or more of these risks or uncertainties occur, or if our underlying assumptions prove to be incorrect, actual events or results may vary significantly from those implied or projected by the forward-looking statements. No forward-looking statement is a guarantee of future performance. You should read this prospectus supplement, the Accompanying Prospectus and the documents that we reference in this prospectus supplement and the Accompanying Prospectus and have filed with the SEC as exhibits to the registration statement of which this prospectus supplement and the Accompanying Prospectus are a part, completely and with the understanding that our actual future results may be materially different from any future results expressed or implied by these forward-looking statements.

The forward-looking statements in this prospectus supplement and the Accompanying Prospectus represent our views as of the respective dates of this prospectus supplement and the Accompanying Prospectus. We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law. You should therefore not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this prospectus supplement.

We are currently an 81.5% owned subsidiary of Ampio. As a result of the spin-off, each holder of Ampio common stock as of 5:00 p.m., New York City time, on December 1, 2015, the record date for the spin-off, will be entitled to:

Ampio stockholders will not be required to pay for our common stock received in the spin-off or to surrender or exchange common stock of Ampio in order to receive our common stock or to take any other action in connection with the spin-off. No vote of Ampio stockholders is required or sought in connection with the distribution, and Ampio stockholders have no appraisal rights in connection with the distribution.

Ampio’s board of directors believes that the distribution is in the best interests of Ampio and its stockholders, and has concluded that the spin-off will provide each company with certain opportunities and benefits. Such opportunities and benefits include:

The Ampio board of directors also considered the probability of successful execution of the distribution and the risks associated therewith, including: potential loss of synergies from operating as a consolidated entity; potential loss of joint purchasing power; potential disruptions to the businesses as a result of the spin-off; risk of being unable to achieve the benefits expected to be attained by the spin-off; risk that the spin-off might not be completed; and one-time costs of executing the spin-off. The Ampio board of directors concluded that, notwithstanding these potentially negative factors, the spin-off would be in the best interests of its stockholders. For more information, see “Risk Factors - Risks Relating to the Spin-off.”

Ampio and Aytu will enter into an agreement pursuant to which the pre-spin-off tax attributes of the consolidated group of which Ampio is the common parent will generally be divided between Ampio and Aytu based upon the proportionate tax attributes that each of Ampio and Aytu contributed to the consolidated group. Ampio and Aytu will agree to certain cooperation and exchange of information rights with respect to the preparation and filing of any tax returns, claims of refunds, any audits, examinations or similar proceedings by a taxing authority with respect to prior tax returns of the companies or arising from or with respect to the distribution or as otherwise needed by the requesting party.

After the spin-off, Ampio will no longer own a controlling interest in our stock. As of November 1, 2015, we had 14,259,693 outstanding shares of common stock, and immediately after the spin-off, approximately 10,399,661 (equal to approximately 72.9%) of these shares will be owned by the Ampio stockholders who receive them in the spin-off. Sales of shares of our stock received in the spin-off could put downward pressure on the price of our common stock.

You will not be required to make any payment for our shares of common stock you receive, nor will you be required to surrender or exchange your Ampio common stock or take any other action in order to receive our shares of common stock to which you are entitled. The spin-off

will not affect the number of outstanding shares of Ampio common stock or any rights of Ampio stockholders, although it is expected to affect the market value of the outstanding Ampio common stock, to the extent the effect of the spin-off is not taken into account by the market price during the period between the announcement of the spin-off on November 2, 2015 and the actual spin-off.

The spin-off will be implemented by Ampio’s distributing to its stockholders one share of our common stock for every five shares of Ampio common stock owned on the record date. As discussed under “Trading of Ampio Common Stock Prior to or on the Distribution Date,” if a holder of record of Ampio common stock sells its shares before or on the distribution date, a due bill will automatically be attached by the NYSE MKT that will require the stockholder to deliver the Aytu shares to the buyer when they are received by the selling Ampio stockholder.

The distribution will be made in book-entry form. For registered Ampio stockholders, our transfer agent will credit their shares of our common stock to book-entry accounts established to hold their shares of our common stock. Book-entry refers to a method of recording stock ownership in a company’s records in which no physical certificates are issued. For stockholders who own Ampio common stock through a bank, a brokerage firm or another nominee, their Aytu common stock will be credited to their accounts by the bank, broker or other nominee. See “When and How You Will Receive Aytu Stock” below. Each share of our common stock that is distributed will be validly issued, fully paid and nonassessable. Following the spin-off, stockholders whose shares are held in book-entry form may request the transfer of our common stock to a brokerage or other account at any time, without charge.

On the distribution date, Ampio will deliver approximately 10,399,661 of its shares of our common stock for distribution by Corporate Stock Transfer, the distribution agent. The distribution agent will cause the shares of our common stock to which you are entitled to be registered in your name or in the “street name” of your bank, brokerage firm or other nominee.

“Street Name” Holders. Many Ampio stockholders have Ampio common stock held in an account with a bank or brokerage firm. If this applies to you, that bank or brokerage firm is the registered holder that holds the shares on your behalf. For stockholders who hold their Ampio common stock in an account with a bank or brokerage firm, our common stock being distributed will be issued to The Depositary Trust Company for the account of your bank or broker, who in turn will credit your account with the shares that you are entitled to receive in the distribution. We anticipate that banks and brokers will generally credit their customers’ accounts with our common stock on or shortly after the distribution date. We encourage you to contact your bank or broker if you have any questions regarding the mechanics of having your shares credited to your account.

Registered Holders. If you are the registered holder of Ampio common stock and hold your Ampio common stock either in physical form or in book-entry form, the shares of our common stock distributed to you will be registered in your name and you will become the holder of record of that number of shares of our common stock. The distribution agent will send you a statement reflecting your ownership of our common stock.

Any fractional common shares equal to or greater than one half will be rounded up into whole shares and any fractional common shares less than one half will be rounded down into whole shares.

It is expected that all fractional shares held in street name will be aggregated and sold by brokers or other nominees according to their standard procedures. You should contact your broker or other nominee for additional details.

The following discussion addresses certain material U.S. federal income tax considerations in respect of the distribution of Aytu common stock by Ampio to its stockholders and of holding Aytu common stock. It does not purport to be a complete analysis of all potential tax effects and does not address the effects of any state, local, estate, alternative minimum, gift or non-U.S. tax laws. This discussion is based upon the Code, Treasury regulations issued thereunder, and judicial and administrative interpretations thereof, each available and as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect and to differing interpretations, all of which could result in U.S. federal income tax considerations different from those described below. No rulings from the Internal Revenue Service, or IRS, have been or are expected to be sought with respect to the matters discussed below. The discussion below is not binding on the IRS or the courts. Accordingly, there can be no assurance that the IRS will not take different positions concerning the U.S. federal income tax consequences of the distribution or of holding Aytu common stock or that any such positions would not be sustained.

This discussion does not address all of the U.S. federal income tax considerations in connection with the distribution or with owning Aytu common stock that might be relevant to a holder of Ampio stock in light of such stockholder’s particular circumstances or to stockholders

subject to special rules, such as certain financial institutions, U.S. expatriates, insurance companies, dealers in securities or currencies, traders in securities or currencies, U.S. holders (as defined below) whose functional currency is not the U.S. dollar, tax-exempt organizations, regulated investment companies, real estate investment trusts, partnerships or other pass-through entities (or investors in such entities), banks, life insurance companies controlled foreign corporations, passive foreign investment companies, and persons holding the Ampio stock as part of a “straddle,” “hedge,” “conversion transaction” or other integrated transaction. In addition, this discussion is limited to persons who hold Ampio stock as capital assets within the meaning of Section 1221 of the Code and who did not receive their Ampio stock in a compensatory transaction such as an option exercise or as restricted stock.

For purposes of this discussion, a “U.S. holder” is a beneficial owner of Ampio stock who is for U.S. federal income tax purposes (i) an individual who is a citizen or resident of the United States; (ii) a corporation or any other entity treated as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United States or any political subdivision thereof; (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) any trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or if a valid election is in place to treat the trust as a U.S. person. For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of Ampio stock who is for U.S. federal income tax purposes (i) a foreign corporation, (ii) a nonresident alien individual, or (iii) a foreign estate or trust that in either case is not subject to U.S. federal income tax on a net income.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) holds Ampio stock, the tax treatment of such partnership and a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A holder that is a partnership, and partners in such partnerships, should consult their tax advisors regarding the tax consequences of the distribution.

Based on a recent appraisal, the aggregate value of all the shares of Aytu stock distributed is expected to be approximately $15.7 million at the time of the distribution. The aggregate value of all the shares of Aytu stock distributed will be determined as of the record date based on an appraisal as of that date, the trading price of Aytu stock as of the record date or a combination thereof, as deemed appropriate by the Company. The IRS will not be bound by this valuation.

Stockholders should consult their tax advisors with respect to the tax consequences of the distribution and the holding of Aytu common stock.

Each taxable U.S. holder of Ampio stock that is receiving shares of Aytu common stock in the distribution will generally be treated as though such stockholder received a taxable distribution in an amount equal to the fair market value at the time of the distribution of the Aytu common stock received.

To the extent the distribution exceeds Ampio’s current and accumulated earnings and profits, the receipt of Aytu common stock will generally be treated as a return of capital to the extent of a U.S. holder’s tax basis in the Ampio common stock and thereafter as capital gain. Capital gains may be taxable at a reduced rate of 20% for U.S. holders who are individuals and who have held their shares of Ampio common stock for more than one year. A stockholder’s tax basis in newly received Aytu common stock will be equal to the fair market value of such common stock at the time of the distribution and the holding period in Aytu common stock will begin the day after the distribution. Ampio expects that it will not have current or accumulated earnings and profits for U.S. federal income tax purposes for the taxable period that includes the distribution. However, as this determination will be based in part on the value of Aytu common stock as determined for purposes of the distribution, there can be no assurance that no portion of the distribution will be taxed as a dividend.

If all or any portion of the Aytu common stock distributed were to be treated as a dividend, subject to certain limitations, such amount would be taxable to U.S. holders who are individuals at a reduced rate of 20%. Corporate U.S. holders may be entitled to a dividends-received deduction with respect to the distribution for U.S. federal income tax purposes, subject to certain limitations and requirements. Corporate U.S. holders should be aware that under certain circumstances, a corporation that receives an “extraordinary dividend” is required to (1) reduce its tax basis (but not below zero) by the portion of such dividend that is not taxed because of the dividends received deduction and (2) treat the non-taxed portion of such dividend as gain from the sale or exchange of the distributing corporation’s stock for the taxable year in which such dividend is received (to the extent that the non-taxed portion of such dividend exceeds such holder’s tax basis). A dividend paid on common stock is generally deemed to be “extraordinary” for this purpose if the amount of such dividend equals or exceeds 10% of the U.S. holder’s adjusted basis in such share of stock.

If the value of the distribution exceeds Ampio’s current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s tax basis in the common stock and thereafter will be treated as capital gain.

Capital gain recognized by a non-U.S. holder generally will not be subject to U.S. federal income tax unless:

An individual non-U.S. holder described in the first bullet point above will be subject to tax on the net gain derived from the sale, exchange, conversion or other taxable disposition under regular graduated U.S. federal income tax rates. An individual non-U.S. holder described in the second bullet point above will be subject to a flat 30% tax on the gain derived from the sale, exchange, conversion or other taxable disposition, which may be offset by U.S. source capital losses, even though such non-U.S. holder is not considered a resident of the United States. A corporate non-U.S. holder that falls under the first bullet point above will be subject to tax on any net gain in the same manner as if such non-U.S. holder was a U.S. person as defined under the Code and, in addition, may be subject to the branch profits tax equal to 30% or at such lower rate as may be specified by an applicable income tax treaty.

Ampio believes that it is not and it does not anticipate becoming a “United States real property holding corporation” for U.S. federal income tax purposes.

If any portion of the distribution were to be treated as a dividend, non-U.S. holders may be subject to a withholding tax at a rate of 30% on the fair market value of the Aytu common stock received by them in the distribution to the extent of their share of Ampio’s current and accumulated earnings and profits, unless such non-U.S. holder provides to Ampio a properly executed (i) IRS Form W-8BEN, W-8BEN-E (or other applicable form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or (ii) IRS Form W-8ECI (or other applicable form) stating that the amount treated as a taxable dividend is not subject to withholding tax because it is effectively connected with such non-U.S. holder’s conduct of a trade or business in the United States (and, if an income tax treaty applies, dividends attributable to a permanent establishment) (“Effectively Connected Dividends”). Effectively Connected Dividends, although not subject to withholding tax, are subject to U.S. federal income tax at the same graduated rates applicable to U.S. persons, net of certain deductions and credits. In addition, dividends received by corporate non-U.S. holders that are Effectively Connected Dividends may be subject to an additional branch profits tax at a rate of 30% (or such lower rate as may be specified in an applicable income tax treaty).

Distributions, if any, made on Aytu common stock generally will be included in a U.S. holder’s income as ordinary dividend income to the extent of Aytu’s current or accumulated earnings and profits. However, for individual U.S. holders, such dividends currently are generally taxed at the lower applicable long-term capital gains rates, provided certain holding period and other requirements are satisfied. Distributions in excess of current and accumulated earnings and profits will be treated as a return of capital to the extent of a U.S. holder’s tax basis in the common stock and thereafter as capital gain from the sale or exchange of such common stock. For corporate U.S. holders, dividends received may be eligible for the dividends-received deduction, subject to applicable limitations.

Upon the sale, exchange or other taxable disposition of Aytu common stock, a U.S. holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash and the fair market value of any property received upon such taxable disposition and (ii) the U.S. holder’s tax basis in the common stock. Such capital gain or loss will be long-term capital gain or loss if a U.S. holder’s holding period in the common stock is more than one year at the time of the taxable disposition. Long-term capital gains recognized by certain non-corporate U.S. holders (including individuals) are generally subject to a reduced rate of U.S. federal income tax. The deductibility of capital losses is subject to certain limits under the Code.

Any dividends paid to a non-U.S. holder with respect to shares of Aytu common stock will be subject to U.S. federal withholding tax at a 30% rate (or lower applicable treaty rate). Effectively Connected Dividends are not subject to withholding tax, but instead are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate tax rates. Certain certification requirements and disclosure requirements must be complied with in order for effectively connected income to be exempt from withholding. Any such effectively connected income received by a foreign corporation may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate (or lower applicable income tax treaty rate).

A non-U.S. holder of shares of Aytu common stock who wishes to claim the benefit of an applicable treaty rate is required to satisfy applicable certification and other requirements. Non-U.S. holders eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

A non-U.S. holder will recognize gain on the sale, exchange, or other taxable disposition of shares of common stock, but such gain generally will not be subject to U.S. federal income tax unless:

An individual non-U.S. holder described in the first bullet point above will be subject to tax on the net gain derived from the sale, exchange, conversion or other taxable disposition under regular graduated United States federal income tax rates. An individual non-U.S. holder described in the second bullet point above will be subject to a flat 30% tax on the gain derived from the sale, exchange, conversion or other taxable disposition, which may be offset by U.S. source capital losses, even though such non-U.S. holder is not considered a resident of the United States. A corporate non-U.S. holder that falls under the first bullet point above will be subject to tax on any net gain in the same manner as if such non-U.S. holder was a United States person as defined under the Code and, in addition, may be subject to the branch profits tax equal to 30% of such non-U.S. holder’s U.S. Trade or Business Income or at such lower rate as may be specified by an applicable income tax treaty.

Aytu believes that it is not and it does not anticipate becoming a “United States real property holding corporation” for U.S. federal income tax purposes.

Information returns will be filed with the IRS in connection with payments to a U.S. holder pursuant to the distribution, dividends on Aytu common stock or the proceeds of a sale of Aytu common stock unless the U.S. holder is an exempt recipient. Under the U.S. federal income tax backup withholding rules, a withholding agent may be required to and may withhold 28% of all payments to which a U.S. holder or other payee is entitled, unless the U.S. holder or other payee (i) is a corporation or comes within other exempt categories and demonstrates this fact or (ii) provides its correct tax identification number (social security number in the case of an individual, or employer identification number in the case of other stockholders), certifies under penalties of perjury that the number is correct, certifies as to no loss of exemption from backup withholding and otherwise complies with the applicable requirements of the backup withholding rules. A U.S. holder can provide an IRS Form W-9 for this purpose. Backup withholding is not an additional tax. Generally, any amounts withheld under the backup withholding rules described above can be credited against a holder’s U.S. federal income tax liability, if any, or refunded provided that the required information is furnished to the IRS in a timely manner. U.S. holders should consult with their own tax advisor as to the qualifications for exemption from backup withholding and the procedures for obtaining such exemption.

A non-U.S. holder will be subject to information reporting requirements and, in certain circumstances, backup withholding (currently at a rate of 28%) may apply, unless the non-U.S. holder certifies under penalties of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the holder is a United States person as defined under the Code) or such holder otherwise establishes an exemption. To avoid backup withholding, non-U.S. holders generally must submit a signed IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable IRS Form W-8. Backup withholding is not an additional tax. Generally, any amounts withheld under the backup withholding rules described above can be credited against a non-U.S. holder’s U.S. federal income tax liability, if any, or refunded provided that the required information is furnished to the IRS in a timely manner. Non-U.S. holders should consult with their own tax advisor as to the qualifications for exemption from backup withholding and the procedures for obtaining such exemption.

A taxpayer who participates in a “reportable transaction” is required to attach a disclosure statement to his, her or its U.S. federal income tax return disclosing such taxpayer’s participation in the transaction. Subject to various exceptions, a reportable transaction can include a transaction that results in a loss exceeding certain thresholds. Failure to comply with these and other reporting requirements could result in the imposition of significant penalties. Stockholders are urged to consult their tax advisors regarding the applicability of any disclosure requirements to them.

Legislation known as the Foreign Account Tax Compliance Act and guidance issued thereunder (“FATCA”) imposes withholding taxes on certain types of payments made to “foreign financial institutions” and certain other foreign entities (including financial intermediaries). FATCA generally imposes withholding at a rate of 30% on payments to certain foreign entities of dividends and the gross proceeds of dispositions of stock unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied or the entity otherwise qualifies for an exemption. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. These

withholding rules generally apply to payments of dividends on Ampio or Aytu stock and payments of gross proceeds from a sale or other disposition of Ampio or Aytu stock on or after January 1, 2019. Stockholders should consult with their own tax advisors regarding the application of FATCA.

The foregoing discussion is not intended to be a complete analysis or description of all potential U.S. federal income tax consequences of the distribution or of holding Aytu common stock. In addition, the discussion does not address tax consequences that may vary with, or are contingent on, a stockholder’s individual circumstances. Moreover, the discussion does not address any non-income tax or any foreign, state, or local tax consequences of the distribution or of holding Aytu common stock. EACH STOCKHOLDER IS STRONGLY URGED TO CONSULT WITH SUCH STOCKHOLDER’S OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES OF THE DISTRIBUTION AND OF HOLDING AYTU COMMON STOCK TO SUCH STOCKHOLDER.

Ampio common stock will trade with an entitlement to the Aytu common stock distributed in connection with the spin-off until the distribution date. Therefore, if you owned Ampio common stock at 5:00 p.m., New York City time, on the record date and sell those shares on or before the distribution date, you will be selling the Aytu common stock that you will receive in connection with the spin-off and a due bill evidencing the obligation to deliver those shares when they are received will automatically be attached by the NYSE MKT. You are encouraged to consult with your financial advisor or broker regarding the financial implications of selling your Ampio common stock before or on the distribution date.

We expect that the distribution will occur on or about January 4, 2016, provided that, among other things:

To the extent that the Ampio board of directors determines that any modifications of the terms and conditions of the distribution materially change such terms and conditions, Ampio will notify its stockholders in a manner reasonably calculated to inform them of such modifications with a press release, Current Report on Form 8-K or other similar means.

This prospectus supplement is being made available to Ampio stockholders solely to provide information to Ampio stockholders who will receive Aytu common stock in the distribution. It is not to be construed as an inducement or encouragement to buy or sell any of our securities. We believe that the information contained in this prospectus supplement and the Accompanying Prospectus is accurate as of the respective dates set forth on the covers. Changes may occur after that date and neither we nor Ampio undertake any obligation to update the information, except to the extent so required by applicable securities laws.

We will not receive any proceeds from the distribution of our common stock in the spin-off.

No consideration will be paid for the shares of our common stock distributed in the spin-off.

The shares to which this prospectus supplement relates will be distributed by Ampio to its stockholders without any payment or other consideration required from the Ampio stockholders. Ampio acquired the shares from us relatively recently in the mergers in which we acquired Vyrix and Luoxis and in an essentially simultaneous cash purchase. If it were determined that at the time Ampio acquired the shares, it did so with a view to distributing them in a spin-off or otherwise, the combination of the acquisitions of the shares by Ampio and the distribution of the shares to its stockholders could constitute, for purposes of the Securities Act of 1933, as amended, an offering of the shares to Ampio’s stockholders, with Ampio constituting an underwriter of that offering. If that were the case, Ampio would be subject to underwriter’s liability with regard to the offering. However, it is unlikely that Ampio stockholders could suffer any damages as a result of the offering, because they are not required to pay anything for the shares they will receive.

Whether or not Ampio is deemed to be an underwriter with regard to the shares it is distributing to its stockholders, there will be no restriction on sales by the Ampio stockholders, except Ampio stockholders, if any, who are affiliates of us, and who will be subject to the restrictions on resales by affiliates contained in SEC Rule 144.

The validity of the common stock to be distributed in the spin-off has been passed upon for us by Wyrick Robbins Yates & Ponton, LLP, Raleigh, North Carolina.

We are a specialty healthcare company concentrating on developing and commercializing products with an initial focus on urological conditions. We are focused primarily on the urological disorders market and initially sexual dysfunction, urological cancers and male infertility. We are currently focused on commercializing our ProstaScint^® product, which we plan to launch through a focused commercial infrastructure in the U.S. while developing corporate relationships outside the U.S. to launch ProstaScint in major healthcare markets around the world. We acquired ProstaScint in May 2015 from Jazz Pharmaceuticals. ProstaScint, which is approved by the U.S. Food and Drug Administration, or FDA, is a marketed biologic imaging agent specifically indicated for the diagnostic staging of prostate cancer patients. We plan to launch the RedoxSYS^® oxidation-reduction potential system, or the RedoxSYS System, into the global research market while developing numerous clinical applications for this potential first-in-class diagnostic device, including an application for the detection of infertility in semen. We have developed a RedoxSYS product line extension called MiOXSYS™ intended for use in male infertility assessment, for which this product is undergoing clinical studies. Further, we are entering late-stage development of our lead therapeutic candidate, Zertane, which is being studied in premature ejaculation.

Our product candidate Zertane is in clinical development for the treatment of premature ejaculation. The premature ejaculation market in the U.S. and Europe is expected to reach over $1.3 billion in annual sales by 2017, representing a projected increase of 10.3% from 2010. According to recent published analyses, premature ejaculation, or PE, is a highly prevalent male sexual dysfunction affecting 20-30% of men worldwide. Based on internal market research and published reports, we believe that PE is up to 1.5-times more prevalent than erectile dysfunction, or ED. Currently, there are no FDA-approved prescription products in the United States to treat PE, and to our knowledge, only two other prescription products have been approved elsewhere in the world. Treatment options for PE have traditionally included antidepressant drugs prescribed “off label,” topical numbing medications, and cognitive behavior therapy or counseling, all of which have had limited effectiveness in treating the disorder. PE therefore represents an area of significant unmet medical need.

By virtue of our recent acquisition of ProstaScint, we are now commercial stage and generating sales for this FDA-approved prostate cancer imaging agent. As prostate cancer is a condition commonly diagnosed and treated by urologists, ProstaScint complements our urology-focused product pipeline. Prostate cancer is the most common cancer among men in the United States, with an estimated 218,000 annual cases (as of 2010). Further, more than 2,200,000 men were alive with some history of prostate cancer in 2006, and over 30,000 U.S. men die each year from the disease. The effect of prostate cancer on healthcare economics is substantial, which makes the need for accurate disease staging critical for treatment and management strategies. The U.S. market for the diagnosis and screening of prostate cancer is expected to total $17.4 billion by 2017, compound annual growth rate, or CAGR of 7.5%.

We are actively developing the global market for the RedoxSYS System across a range of applications. Specifically, we have begun commercializing RedoxSYS System for research use through direct selling, distribution partners, and academic collaborators. Over the past 18 months, we have engaged in over 60 trials around the world whereby prominent researchers are implementing oxidation-reduction potential as a marker in both chronic and acute illnesses and disorders in both clinical research as well as basic science research.

Through our extensive network of researchers, the RedoxSYS System has demonstrated the potential to have broad clinical applications. Studies are now underway at a major U.S. university in the area of male infertility. Thus, we have developed the MiOXSYS System to uniquely detect oxidation-reduction potential in semen specimens. Male infertility is prevalent, underserved, and oxidative stress is widely implicated in its pathophysiology. The global male infertility market is expected to grow to over $300 million by 2020 with a CAGR of nearly 5% from 2013 to 2020. Oxidative stress is broadly implicated in the pathophysiology of oxidative stress, yet very few diagnostic tools exist to effectively measure oxidative stress levels in men. However, antioxidants are widely available and recommended to infertile men. With the introduction of the MiOXSYS System, we believe for the first time there will be an easy and effective diagnostic tool to assess degree of oxidative stress, sperm motility and morphology, and potentially enabling the monitor of patients’ responses to antioxidant therapy as a treatment regimen for infertility.

The technology underpinning the RedoxSYS and MiOXSYS systems was developed by Luoxis Diagnostics, Inc. in the two years immediately preceding the merger between Luoxis, Vyrix Pharmaceuticals, Inc., and us (under our former name of Rosewind Corporation) in April 2015. Upon the consummation of the merger, the RedoxSYS System and MiOXSYS System became our assets. Prior to the incorporation of Luoxis, the predecessor technologies that are now incorporated into these products were developed by the research team of Dr. David Bar-Or when he was at DMI BioSciences, Inc. and subsequently at Ampio Pharmaceuticals, Inc.

Our premature ejaculation product candidate, Zertane, is a specifically formulated orally disintegrating tablet, or ODT, of tramadol hydrochloride patented for the on-demand treatment of PE. Zertane is being developed utilizing a regulatory pathway pursuant to Section 505(b)(2) of the Food, Drug and Cosmetic Act, as amended, or the FDCA, as the active ingredient is already well characterized for the treatment of pain, and we are relying on the FDA’s finding of safety of tramadol hydrochloride to support its use in a new indication, PE, at a lower dose. If we receive marketing approval for Zertane, we believe it will be the first commercial product approved by the FDA for PE.

Effective August 18, 2014 the Drug Enforcement Administration, or DEA, began classifying tramadol as a Schedule IV substance, including its salts, isomers, and salts of isomers. Tramadol has a low potential for abuse relative to the drugs or substances in Schedule III and has a currently accepted medical use in treatment in the U.S. for moderate to moderately severe pain. We expect the same classification for Zertane regardless of the indication, including premature ejaculation. As a result of this classification, manufacturers are required to print “C-IV” on the labeling of commercial containers of tramadol. It is unclear as to what extent the FDA and/or the DEA would expect manufacturers of tramadol-containing products to further control its distribution or monitor its use. However, we do not expect this classification to adversely affect the commercial potential for Zertane considering that tramadol has a long history of use and a low potential for abuse.

The method of use patents covering the use of tramadol for premature ejaculation were originally developed and held by Ampio (our parent predecessor company). However, these patents and all related intellectual property were assigned to Vyrix when it was established as an Ampio subsidiary. Following the Merger of Vyrix, Luoxis and us, the patents were transferred and are now solely owned by us.

A key part of our strategy is to identify, acquire, license, or otherwise promote marketed, complementary urology assets in order to establish a commercial footprint and generate revenues for already-approved or near-term medical products. To that end we acquired ProstaScint from Jazz Pharmaceuticals shortly after the Merger. ProstaScint received FDA approval on October 28, 1996 and was initially marketed by Cytogen Corporation.

ProstaScint (capromab pendetide) is a radio-labeled monoclonal antibody, which is a biologic product that targets a specific antigen. ProstaScint targets Prostate Specific Membrane Antigen (PSMA), a protein uniquely expressed by prostate tissue. Indium (In 111) is attached to the proprietary, mouse-derived antibody. The radiolabeled antibody is infused into the patient and is taken up by prostate cancer cells which can be detected and visualized with single-photon emission tomography (SPECT). ProstaScint has been shown to be clinically effective in determining the course of treatment for a patient who has had a prostatectomy and/or has suspected metastasis (spread of the cancer cells beyond the prostate). Further, ProstaScint has demonstrated efficacy in newly diagnosed patients classified as high-risk or with recurrent prostate cancer.

Multiple clinical studies have been conducted in the United States and published in peer-reviewed publications. These studies consistently demonstrate substantial clinical efficacy of ProstaScint in staging prostate cancer patients and specifically identifying whether the cancer is confined to the prostate or has metastasized to other parts of the body. Through more accurate clinical staging and identification of metastatic prostate cancer, clinicians are able to better direct therapeutic interventions and improve outcomes.

We completed the development of the RedoxSYS System during the two years preceding the Merger. In 2014, we received ISO 13485 certification, demonstrating our compliance with global quality standards in medical device manufacturing. This enables the launch of the RedoxSYS System into the research market around the world. We also received a CE marking in Europe and Health Canada clearance to begin the market development of the RedoxSYS System as a clinical diagnostic in Europe, Canada, and elsewhere around the world where CE marking is recognized. We launched sales efforts into the research market in late 2014 and since that time have already placed the RedoxSYS System at a number of prominent research centers in the United States, Europe, Israel, Japan, Taiwan, Singapore and Korea.

As part of our strategy to develop future clinical applications of the RedoxSYS System, we have conducted initial studies in male reproductive health. Male infertility is a significant medical condition in which oxidative stress is well known to play a substantial role. As such, we believe developing a clinical application to assess oxidative stress levels with the uniquely designed and programmed MiOXSYS System for semen analysis represents a significant commercial opportunity. Oxidative stress is well established as a leading contributing factor to male infertility. Further, a significant proportion of male infertility remains unexplained in part because of the lack of standardized tests available to clinicians and researchers to assess oxidative stress in semen and seminal plasma. This lack of standardization has resulted in poor implementation of semen and plasma analysis around the world. Further, currently available tests are cumbersome, time consuming to perform, and costly.

We have conducted initial proof-of-concept clinical studies in male infertility with a leading research center in the United States, which demonstrates that oxidation-reduction potential effectively measures oxidative stress levels in semen and seminal plasma – and that these levels strongly correlate with established markers of infertility. Semen analysis studies are routinely conducted to assess causes of infertility, so we expect clinicians and oxidative stress researchers to readily integrate the MiOXSYS System into routine use upon the completion of more extensive studies and regulatory clearance for this use. Additional studies are now in the late planning stages that will evaluate the MiOXSYS System’s performance in the detection of oxidative stress levels and correlations with key semen parameters in both healthy and infertile males. The MiOXSYS System must receive 510(k) de novo clearance from the FDA before we can market it for clinical use in the United States. Of the $300 million male infertility market projected for 2020, the North American, Middle Eastern, and Asia Pacific markets dominate due to prevalence, awareness of treatment, and availability of treatment resources. Thus, it is important that we have already established distribution relationships and direct access to major oxidative stress researchers in many of these important markets.

An attractive aspect of the reproductive health market relates to reimbursement, as infertility treatments and the associated diagnostic tests are generally paid directly by patients. The current infertility treatments and associated diagnostics typically cost in excess of $10,000 per treatment cycle, so the addition of a moderately priced oxidative stress test would consume nominal relative costs while providing specific, actionable information needed to improve the oxidative status of infertile patients. The current infertility treatments include antioxidant supplements and lifestyle modifications that lower oxidative stress (e.g., smoking cessation, exercise, dietary changes, etc.), so the measurements reported by the MiOXSYS System could effectively guide treatment in the infertile patients.

We have an extensive range of intellectual property across our primary assets, Zertane, MiOXSYS, and RedoxSYS. We have patent protection in the United States and several other large markets worldwide. Specifically, we have numerous patents issued and pending for the RedoxSYS/MiOXSYS systems and their use in the U.S., Europe, Israel, and major markets in Asia inclusive of Japan, Korea, China, and the Middle East. Further, we have patent protection in the United States and several other large markets worldwide for the use of tramadol hydrochloride to treat PE. We also have intellectual property specifically covering Zertane-ED, our product candidate to treat comorbid premature ejaculation and erectile dysfunction, or ED, that has issued patents in several large markets worldwide and is pending in the United States. However, we are not actively developing Zertane-ED at this time.

On October 5, 2015, we purchased from FSC Laboratories, Inc. the assets related to its product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in process and all marketing and sales assets and materials related solely to Primsol. Primsol is the only FDA-approved liquid formulation of trimethoprim, an antibiotic that is well established in current guidelines for treating uncomplicated urinary tract infections (UTIs). This differentiated product is appropriate for UTI patients that have difficulty swallowing tablets, such as the elderly, and particularly for patients that experience adverse reactions to sulfamethoxazole (“sulfa”). This acquisition adds a second established brand to our product portfolio. We expect to benefit from and continue to grow Primsol’s established base of prescribers, which already includes a significant proportion of urologists despite the fact that it has not been previously marketed to these specialists. This allows us to utilize the same sales channel as ProstaScint, leading to potential commercial synergies. For a description of the Primsol acquisition, see “Recent Developments.”

Our lead therapeutic product candidate, Zertane, is a specifically formulated orally disintegrating tablet, or ODT, of tramadol hydrochloride patented for the on-demand treatment of PE. Zertane is being developed utilizing a regulatory pathway pursuant to Section 505(b)(2) of the Food, Drug and Cosmetic Act, as amended, or the FDCA, as the active ingredient is already well characterized for the treatment of pain, and we are relying on the FDA’s finding of safety of tramadol hydrochloride to support its use in a new indication, PE, at a lower dose. If we receive marketing approval for Zertane, we believe it will be the first commercial product approved by the FDA for PE.

There are three main types of NDAs, which are covered by Section 505 of the FDCA: (1) an application that contains full reports of investigations of safety and efficacy (Section 505(b)(1)); (2) an application that contains full reports of investigations of safety and effectiveness but where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the application has not obtained a right of reference (Section 505(b)(2)); and (3) an application that contains information to show that the proposed product is identical in active ingredient, dosage form, strength, route of administration, labeling, quality, performance characteristics, and intended use, among other things, to a previously approved product (Section 505(j)). Section 505(b)(2) expressly permits the FDA to rely, for approval of an NDA, on data not developed by the applicant. In the preIND briefing meeting with Ampio and in June 2012, the FDA agreed that our NDA may be submitted under Section 505(b)(2). As such, we intend to rely on studies published in the scientific literature and reference FDA-approved NDAs for tramadol-containing products (NDAs 21-693, 20-281 and 21-692) to support the safety and efficacy demonstrated in our clinical program. Relying on Section 505(b)(2) is advantageous because we or our collaborators may not be required (i) to perform the full range of safety and efficacy trials that is otherwise required to secure approval of a new drug, and (ii) obtain a “right of reference” from the applicant that obtained approval of the previously approved drug. However, a Section 505(b)(2) application must support the proposed change of the previously approved drug by including necessary and adequate information, as determined by the FDA, and the FDA may still require us to perform a portion or the full range of safety and efficacy trials. There can be no assurance that we would be successful under any Section 505(b)(2) application.

According to recent published analyses, PE is a highly prevalent male sexual dysfunction affecting 20-30% of men worldwide. Based on internal market research and published reports, we believe that PE is up to 1.5-times more prevalent than erectile dysfunction. Currently, there are no FDA-approved prescription products in the United States to treat PE, and to our knowledge, only one oral prescription product has been approved elsewhere in the world. Treatment options for PE have traditionally included antidepressant drugs prescribed “off label,” topical numbing medications, and cognitive behavior therapy or counseling, all of which have had limited effectiveness in treating the disorder. PE therefore represents an area of significant unmet medical need.

By virtue of significant development work performed by a previous corporate partner, Zertane has already been evaluated outside the United States in two Phase 1 clinical trials, two Phase 2 clinical trials and two Phase 3 clinical trials. This development work has demonstrated a favorable safety and efficacy profile of Zertane in men with PE and helped inform the design and endpoints of the Phase 3 clinical trials we will need to obtain FDA approval. Furthermore, the safety and pharmacology of the drug substance in Zertane, tramadol hydrochloride, is well characterized, which we believe will eliminate the need for us to conduct additional pre-clinical studies and safety trials. We believe we are well positioned to initiate Phase 3 clinical trials with Zertane in the United States. Upon completion of the trials, if successful, we plan to submit a New Drug Application, or NDA, and subsequently market Zertane in the United States, if approved.

Our strategy for Zertane is focused on the initiation and completion of the Phase 3 clinical program in the United States and the development of worldwide commercialization and marketing partnerships. We expect to finalize clinical development of Zertane, seek FDA marketing approval and – if approved—commercialize the product candidate in the United States either directly or via partnerships. While we have not yet submitted an IND for Zertane to the FDA that would allow us to initiate the planned Phase 3 trial, we expect to submit the IND in the second half of 2015. We will seek partnerships to commercialize Zertane in rest of world, or ROW, 6 markets. We already have partnerships in place to market Zertane in South Korea (Daewoong Pharmaceutical Co., Ltd.) and Brazil (FBM Farma Industria Farmaceutica), which could provide near-term revenue for us if, working with our partners, we are able to successfully obtain regulatory approval in those countries. In addition, we recently entered into an agreement with Endo Ventures Limited, which recently acquired Paladin Labs Inc., or Paladin, a leading Canadian specialty pharmaceutical company, to provide exclusive rights to market, sell and distribute Zertane in Canada, the Republic of South Africa, certain countries in Sub-Saharan Africa, Colombia and Latin America.

PE is a significant unmet medical need in the United States and worldwide as it causes significant emotional distress for affected men and their partners. According to an article published in European Urology in 2010 and a survey published in the Journal of the American Medical Association (JAMA) in 1999, PE is a highly prevalent male sexual dysfunction affecting 20-30% of men worldwide. However, most prevalence data on PE is based on patient surveys, which are inherently subjective, and therefore some of the men surveyed may not have PE as it is defined by major medical societies. In a 2007 study published in European Urology, the incidence of PE was assessed via a web-based survey of 12,133 men ages 18-70 in the United States, Germany and Italy. In this survey, 2,754 or 22.7% of the men reported that they suffer from PE. The vast majority (87.9%) of men with PE wished that they had more control over time to climax. Additionally, a majority (57.6%) of the men surveyed reported that they would seek medical treatment if they knew that a pill to control ejaculation were available. We believe men would also ask their doctor about treatment options if their partner suggested it. Additional primary company market research indicated that over 66% of patients that see a urologist for PE were self-referred, which we believe further demonstrates that PE is a condition for which patients are actively seeking treatment.

Presently, there are no approved prescription pharmaceuticals in the United States to treat PE and only two pharmaceuticals known to be approved elsewhere in the world. Current “off label” or unapproved therapies used to treat PE carry with them unwanted side effects and inconsistent or limited effectiveness. Topical over-the-counter, or OTC, options are not preferred due to route of administration and may also have an impact on partner satisfaction. Oral therapeutics, specifically selective serotonin reuptake inhibitors, or SSRIs, carry potentially significant side effects; the most notable of which is diminished libido. PDE-5 inhibitors have been prescribed “off label” for PE but have not demonstrated efficacy. Outside of oral or topical therapeutics, non-medical options include behavioral therapy and relationship counseling, both of which can be time consuming and stressful and frequently ineffective for men and their partners.

We believe patients and their partners are generally dissatisfied with existing pharmacologic and non-pharmacologic treatments for PE. Based on primary market research commissioned by us, which included discussions with a cross section of clinicians that treat patients with PE, we believe that there are significant issues with existing PE treatments demonstrating a real need for a safe and effective, FDA-approved product to treat PE that does not have a ramp-up period.

Our lead product candidate, Zertane for premature ejaculation, contains 89 mg tramadol hydrochloride in an orally dissolving tablet, or ODT. Tramadol hydrochloride is a well-established, centrally acting synthetic analgesic and has been used for more than 30 years as a treatment for moderate to severe pain. The drug and its active metabolite (M1, O-desmethyltramadol) act as an opiate agonist, apparently by selective activity at the µ-receptor. Although the mechanism by which tramadol hydrochloride delays ejaculation has not been identified, numerous laboratory studies have shown that tramadol hydrochloride also acts as an N-methyl-D-aspartate receptor antagonist, 5-hydroxytryptamine type 2C receptor antagonist, 5 nicotinic acetylcholine receptor antagonist, M1 and M3 muscarinic acetylcholine receptor antagonist, and a serotonin and norepinephrine modulator. It is possible that one

or a combination of these effects leads to a delay in ejaculation. The relative contribution of tramadol hydrochloride versus its M1 metabolite to delay ejaculation is unknown. However, the metabolite is six times more potent than the parent drug in producing analgesia in animal models and 200 times more potent in µ-receptor binding. As a pain medication, tramadol hydrochloride has been associated with certain adverse effects including dizziness, nausea, constipation, vertigo, headache, vomiting and drowsiness. However, we intend that our labeling for Zertane, if regulatory approval is obtained, will suggest “as required” dosing before sexual intercourse and not to exceed one tablet per day. Based on previous clinical studies, we believe that limiting the dosing to no more than once per day will minimize any side effects.

On May 20, 2015, we acquired ProstaScint from Jazz Pharmaceuticals. ProstaScint is already approved by the FDA and is generating revenues. As such, we expect to launch a commercial infrastructure in order to support increased sales and distribution of ProstaScint in the U.S. ProstaScint, or capromab pendetide, is a radio-labeled monoclonal antibody, which is a biologic product that targets a specific antigen. ProstaScint targets Prostate Specific Membrane Antigen (PSMA), a protein uniquely expressed by prostate tissue. A radioactive substance called Indium In 111 is attached to the proprietary, mouse-derived antibody. The radiolabeled antibody is infused into the patient and is taken up by prostate cancer cells which can be detected and visualized with a special nuclear medicine scan (single-photon emission tomography, or SPECT). ProstaScint has been shown to be clinically effective in determining the course of treatment for a patient who has had a prostatectomy and/or has suspected metastasis (spread of the cancer cells beyond the prostate). Further, ProstaScint has demonstrated efficacy in newly diagnosed patients classified as High Risk or with recurrent prostate cancer. In addition to U.S. approval ProstaScint has also been approved by Health Canada.

ProstaScint fills an important medical need in the detection of a common illness facing a significant number of men in the U.S. and around the world. Prostate cancer is the most common cancer among men in the United States, with an estimated 218,000 annual cases (as of 2010). Further, more than 1,800,000 men are alive with some history of prostate cancer, and over 30,000 U.S. men die each year from the disease. The effect of prostate cancer on healthcare economics is substantial, which makes the need for accurate disease staging critical for treatment and management strategies. The U.S. market for the diagnosis and screening of prostate cancer is expected to total $17.4 billion in 2017, a CAGR of 7.5%.

ProstaScint has several unique selling features that we believe will enable significant sales growth and regular use by healthcare providers diagnosing and treating prostate cancer. ProstaScint is the only imaging agent that specifically targets prostate cancer cells and demonstrates high sensitivity, specificity, and accuracy. In multiple clinical studies researchers have shown that when SPECT/CT scans were used in patients pre-treated with ProstaScint, ProstaScint imaging was highly sensitive in detecting prostate cancer and significantly predictive of 10-year biochemical disease free survival in prostate cancer patients (86.6% vs. 65.5%; p=0.0014). Importantly, ProstaScint is already approved by the FDA with a history of sales in the U.S. Additionally, the American Cancer Society specifically recognizes ProstaScint by name in current prostate cancer diagnosis guidelines.

Radiation oncology experts have published numerous papers expressing the potential for expanded use of ProstaScint in prostate cancer imaging due to advances in imaging technologies since its FDA approval in 1996. Since the early 2000s significantly greater image resolution has been enabled due to the advent of dual head cameras (and improved imaging in general) along with the use of co-registered images where radiologists now combine the images of SPECT and computerized tomography (CT) or magnetic resonance imaging (MRI).

Our leading diagnostic product candidate, the RedoxSYS System, is now fully developed for research use. RedoxSYS is a novel, portable device that measures oxidation-reduction potential, or ORP, a global measure of oxidative stress. This system is the first and only system that measures ORP in biologic specimens to provide a complete measure of redox balance, which is broadly implicated across a wide range of both acute and chronic conditions. To date, Canadian and European regulators have characterized RedoxSYS System as Class II medical device and regulated them accordingly. Classification of a medical device as Class II in Europe and Canada indicates that the device is generally regarded as posing medium risk, and non-invasive medical devices that come into contact with injured skin are generally classified as Class II. As we have conducted initial validation studies with the RedoxSYS System across a range of conditions and obtained a CE marking in Europe and Health Canada clearance to begin the market development of the RedoxSYS System as a clinical diagnostic in Europe, Canada, and elsewhere around the world where CE marking is recognized, we are now initiating commercialization for use of the RedoxSYS System as a research tool. By employing a focused commercial infrastructure and a focused network of distributors around the world, we believe we can efficiently penetrate the academic and industry-based research centers who study oxidative stress. With this growth in the research market, we intend to develop clinical applications for the RedoxSYS System.

Our strategy for the RedoxSYS System is to continue deployment of this system at leading academic centers around the world, develop research collaborations with key opinion leaders in oxidative stress research, identify clinical applications for the platform, and aggressively pursue infertility studies to establish efficacy of the system in this setting of care. In 2013 and 2014, we deployed the RedoxSYS System around the world in the development of numerous future clinical applications. While many areas of study have been undertaken, we have focused research resources on high-value areas where significant medical needs remain unmet. Given our initial orientation around trauma, the studies completed thus far have focused on large conditions related to critical care. These initial studies demonstrated the initial clinical validation for the RedoxSYS System and represent substantial opportunities as growth applications and markets following initial entry into the research and infertility markets. As our direct commercial efforts will focus on male infertility, we expect that other areas of clinical use would be pursued through partnerships with corporate partners established in these non-urological clinical channels. A significant potential opportunity that has presented promise through our research is the application of ORP in the study of male infertility. ORP represents a unique approach to assessing oxidative stress in male infertility as it relates to semen analysis, and early clinical studies have been conducted. We are now beginning larger-scale clinical studies with a globally recognized U.S. university in male infertility. As such we have developed a RedoxSYS System line extension called MiOXSYS specifically designed and programmed to detect oxidative stress in semen specimens. Oxidative stress is widely assessed in semen analysis laboratories as part of male infertility assessment, and we believe the MiOXSYS System, if proven effective, will provide a simple, comprehensive solution to oxidative stress detection and management of antioxidant and lifestyle intervention in this underserved market.

We plan to augment our core development and commercial assets through efficient identification of complementary therapeutics, devices, and diagnostics related to urological disorders. We intend to seek assets that are near commercial stage or already generating revenues. Further, we intend to seek to acquire products through asset purchases, licensing, co-development, or collaborative commercial arrangements (co-promotions, co-marketing, etc.).

Our management team has extensive experience across a wide range of business development activities and have in-licensed or acquired products from large, mid-sized, and small enterprises in the United States and abroad. Through an assertive product and business development approach, we expect that we will rapidly advance our internal products as well as externally sourced assets.

On October 5, 2015, we entered into and closed on an asset purchase agreement with FSC Laboratories, Inc. (the “Seller”). Pursuant to the agreement, we purchased assets related to the Seller’s product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in process and all marketing and sales assets and materials related solely to Primsol (together, the “Primsol Business”), and assumed certain of the Seller’s liabilities, including those related to the sale and marketing of Primsol arising after the closing.

We paid $500,000 at closing for the Primsol Business and we agreed to pay an additional $141,694 payable within five days after transfer of the Primsol-related product inventory. We also agreed to pay an additional (a) $500,000 payable no later than March 31, 2016, (b) $500,000 payable no later than June 30, 2016, and (c) $250,000 payable no later than September 30, 2016 (together, the “Installment Payments”) for a total purchase price of $1,891,694.

The agreement contains customary representations and warranties and covenants by each party. The agreement contains customary indemnification provisions by each party, including, subject to certain limitations, the indemnification by each party for any losses arising out of any breach of the other party’s representations or warranties or any breach or failure to perform any of its covenants under the agreement, as well as any liabilities related to the Primsol Business prior to the closing (as to us) and after the closing (as to the Seller). Our sole right to and source of indemnification under the agreement is an offset against the Installment Payments and payment of such offset amount into an escrow account.

The agreement also provides that for a period of one year after the closing the Seller will not directly or indirectly sell, market, promote, advertise or distribute anywhere in the world any urinary tract anti-infective pharmaceutical or treatment product containing trimethoprim.

On October 8, 2015, we and Biovest International, Inc., or Biovest, entered into a Master Services Agreement, pursuant to which Biovest is to provide manufacturing services to us. The agreement provides that we may engage Biovest from time to time to provide services in accordance with mutually agreed upon project addendums and purchase orders. We expect to use the agreement from time to time for manufacturing services, including without limitation, the manufacturing, processing, quality control testing, release or storage of our products. The agreement provides customary terms and conditions, including those for performance of services by Biovest in compliance with project addendums, industry standards, regulatory standards and all applicable laws. Biovest will be responsible for obtaining and maintaining all governmental approvals, at our expense, during the term of the agreement. The agreement has a term of four years, provided that either party may terminate the agreement or any project addendum under the agreement on 30 days written notice of a material breach under the agreement. In addition, we may terminate the agreement or any project addendum under the agreement upon 180 days written notice for any reason.

In conjunction with entering into the agreement, we submitted a work order to Biovest to provide us with active pharmaceutical ingredient for ProstaScint over a four-year period at a total cost of $5,000,000, of which we paid $1,000,000 upon submission of the work order.

We were incorporated as Rosewind Corporation on August 9, 2002 in the State of Colorado.

Vyrix Pharmaceuticals, Inc., or Vyrix, was incorporated under the laws of the State of Delaware on November 18, 2013 and was wholly owned by Ampio Pharmaceuticals, Inc. (NYSE MKT: AMPE), or Ampio, immediately prior to the completion of the Merger (defined below). Vyrix was previously a carve-out of the sexual dysfunction therapeutics business, including the late-stage men’s health product candidates, Zertane and Zertane-ED, from Ampio, which carve out was announced in December 2013. Luoxis Diagnostics, Inc., or Luoxis, was incorporated under the laws of the State of Delaware on January 24, 2013 and was majority owned by Ampio immediately prior to the completion of the Merger. Luoxis was focused on initially developing and advancing the RedoxSYS System. The MiOXSYS System was developed following the completed development of the RedoxSYS System.

On March 20, 2015, Rosewind formed Rosewind Merger Sub V, Inc. and Rosewind Merger Sub L, Inc., each a wholly-owned subsidiary formed for the purpose of the Merger, and on April 16, 2015, Rosewind Merger Sub V, Inc. merged with and into Vyrix and Rosewind Merger Sub L, Inc. merged with and into Luoxis, and Vyrix and Luoxis became subsidiaries of Rosewind. Immediately thereafter, Vyrix and Luoxis merged with and into Rosewind with Rosewind as the surviving corporation (herein referred to as the Merger).

Concurrent with the closing of the Merger, Rosewind abandoned its pre-merger business plans to develop a sailing school, and we now solely pursue the specialty healthcare market, focusing on urological related conditions, including the business of Vyrix and Luoxis.

On June 8, 2015, we (i) reincorporated as a domestic Delaware corporation under Delaware General Corporate Law and changed our name from Rosewind Corporation to Aytu BioScience, Inc., and (ii) effected a reverse stock split in which each common stock holder received one share of common stock for each every 12.174 shares outstanding (herein referred to as the Reverse Stock Split). All share and per share amounts in this prospectus have been adjusted to reflect the effect of the Reverse Stock Split.

This prospectus relates to the resale by the selling stockholders identified in this prospectus of up to 13,168,390 shares of our common stock, as follows:

We will not receive any of the proceeds from the sale of shares in this offering. The selling stockholders will receive all net proceeds from the sale of shares of our common stock in this offering.

We have never paid dividends on our capital stock and do not anticipate paying any dividends for the foreseeable future. See “Dividend Policy.”

Investing in our common stock includes a high degree of risk. Prior to making a decision about investing in our common stock, you should consider carefully the specific factors discussed below, together with all of the other information contained in this prospectus. If any of the following risks actually occurs, our business, financial condition, results of operations and future prospects would likely be materially and adversely affected. This could cause the market price of our common stock to decline and could cause you to lose all or part of your investment.

We have limited operating history, have incurred losses, and can give no assurance of profitability.

We are a clinical-stage healthcare company with a limited operating history. We have not generated material revenue to date and are not profitable, and have incurred losses in each year since our inception. Our net loss for the years ended June 30, 2015 and 2014 was $7.7 million and $5.6 million, respectively. We have not demonstrated the ability to be a profit-generating enterprise, and without significant financing, there is substantial doubt about our ability to continue as a going concern. We expect to incur substantial losses for the foreseeable future. Our ability to generate revenue is uncertain, and we may never achieve profitability. We have a very limited operating history on which investors can evaluate our potential for future success. Potential investors should evaluate us in light of the expenses, delays, uncertainties, and complications typically encountered by early-stage healthcare businesses, many of which will be beyond our control. These risks include the following:

As a result of our limited operating history, and the increasingly competitive nature of the markets in which we compete, our historical financial data, which, prior to April 16, 2015, consists of allocations of expenses from Ampio, is of limited value in anticipating future operating expenses. Our planned expense levels will be based in part on our expectations concerning future operations, which is difficult to forecast accurately based on our stage of development. We may be unable to adjust spending in a timely manner to compensate for any unexpected budgetary shortfall.

We have not received any material revenues from the commercialization of our products or product candidates and might not receive significant revenues from the commercialization of products and our product candidates in the near term. Even though ProstaScint is an approved drug that we are marketing, we only acquired it in May 2015 and have limited experience on which to base the revenue we could expect to receive. To obtain revenues from our products and product candidates, we must succeed, either alone or with others, in a range of challenging activities, including expanding markets for our existing products and completing clinical trials of our product candidates, obtaining positive results from the clinical trials, achieving marketing approval for these product candidates, manufacturing, marketing and selling our existing products and those products for which we, or our collaborators, may obtain marketing approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from private insurance or government payors. We, and our collaborators, if any, may never succeed in these activities and, even if we do, or one of our collaborators does, we may never generate revenues that are sufficient enough for us to achieve profitability.

We may need to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain necessary capital when needed may force us to delay, limit or terminate our product expansion and development efforts or other operations.

We are currently advancing our product candidates through clinical development. Developing product candidates is expensive, lengthy and risky, and we expect our research and development expenses to increase substantially in connection with our ongoing activities, particularly as we advance Zertane into two planned Phase 3 clinical trials in the United States and develop the RedoxSYS System for additional applications. In addition, we are expending resources to expand the market for ProstaScint, which might not be successful or might take longer and be more expensive than anticipated.

As of June 30, 2015, our cash and cash equivalents were $7.4 million. Our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements or a combination of these approaches. In any event, we will require additional capital to obtain regulatory approval for, and to commercialize, our product candidates. Raising funds in the current economic environment, as well our lack of operating history, may present additional challenges. Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic considerations.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to expand any existing product or develop and commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our shares to decline. The sale of additional equity or convertible securities would dilute all of our stockholders. The incurrence of indebtedness would result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any product candidate or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially affect our business, financial condition and results of operations.

If we do not obtain the capital necessary to fund our operations, we will be unable to successfully expand, develop, obtain regulatory approval of, and commercialize, our products and product candidates.

The development of pharmaceutical products, medical diagnostics and medical devices is capital-intensive. We anticipate we may require additional financing to continue to fund our operations. Our future capital requirements will depend on, and could increase significantly as a result of, many factors including:

Until we can generate significant continuing revenues, we expect to satisfy our future cash needs through collaboration arrangements, sales of our securities, debt financings, or by out-licensing one or more of our product candidates. Dislocations in the financial markets have generally made equity and debt financing more difficult to obtain, and may have a material adverse effect on our ability to meet our fundraising needs. We cannot be certain that additional funding will be available to us on acceptable terms, if at all. If funds are not available, we may be required to delay, reduce the scope of, or eliminate one or more of our technologies, research or development programs or our commercialization efforts. Additional funding, if obtained, may significantly dilute existing shareholders if that financing is obtained through issuing equity or instruments convertible into equity.

We will incur increased costs associated with, and our management will need to devote substantial time and effort to, compliance with public company reporting and other requirements.

As a public company, we will incur significant legal, accounting and other expenses that Vyrix and Luoxis did not incur as private companies. In addition, the rules and regulations of the SEC and any national securities exchange to which we may be subject in the future impose numerous requirements on public companies, including requirements relating to our corporate governance practices, with which we will need to comply. Further, we will be required to, among other things, file annual, quarterly and current reports with respect to our business and operating results. Based on currently available information and assumptions, we estimate that we will incur approximately $500,000 in expenses on an annual basis as a direct result of the requirements of being a publicly traded company. Our management and other personnel will need to devote substantial time to gaining expertise regarding operations as a public company and compliance with applicable laws and regulations, and our efforts and initiatives to comply with those requirements could be expensive.

Risks Related to Product Development, Regulatory Approval and Commercialization

We cannot be certain that we will be able to obtain regulatory approval for, or successfully commercialize, any of our product candidates.

We may not be able to develop our current or any future product candidates. Our product candidates will require substantial additional clinical development, testing, and regulatory approval before we are permitted to commence commercialization. The clinical trials of our product candidates are, and the manufacturing and marketing of our product candidates will be, subject to extensive and rigorous review and regulation by numerous government authorities in the United States and in other countries where we intend to test and, if approved, market any product candidate. Before obtaining regulatory approvals for the commercial sale of any product candidate, we must demonstrate through pre-clinical testing and clinical trials that the product candidate is safe and effective for use in each target indication. This process can take many years and may include post-marketing studies and surveillance, which will require the expenditure of substantial resources. Of the large number of drugs in development in the U.S., only a small percentage successfully completes the FDA regulatory approval process and is commercialized. Accordingly, even if we are able to obtain the requisite financing to continue to fund our development and clinical programs, we cannot assure you that any of our product candidates will be successfully developed or commercialized.

We are not permitted to market a product in the U.S. until we receive approval of a New Drug Application, or an NDA, for that product from the FDA, or in any foreign countries until we receive the requisite approval from such countries. Obtaining approval of an NDA is a complex, lengthy, expensive and uncertain process, and the FDA may delay, limit or deny approval of any product candidate for many reasons, including, among others:

These same risks apply to applicable foreign regulatory agencies from whom we may seek approval for any of our product candidates.

Any of these factors, many of which are beyond our control, could jeopardize our ability to obtain regulatory approval for and successfully market any product candidate. Moreover, because a substantial portion of our business is dependent upon our existing product candidates, any such setback in our pursuit of regulatory approval would have a material adverse effect on our business and prospects.

Favorable results in the prior clinical trials of Zertane outside of the United States may not be predictive of the results in our planned Phase 3 clinical trials of Zertane in the United States or the designs of our Phase 3 clinical trials may be inadequate for FDA approval.

A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after achieving promising results in earlier-stage development. The prior clinical trials of Zertane showed favorable safety and efficacy data; however, we will have different enrollment criteria in our planned Phase 3 clinical trials. In the Phase 2 clinical trials, we were able to enroll patients utilizing a broader definition of PE.

Ejaculation latency, most commonly quantified using intravaginal ejaculation latency time, or IELT, is a dominant component of PE assessment in clinical trials. IELT is defined as the time between vaginal intromission and intravaginal ejaculation. Although a standard cut-off for ejaculatory latency does not exist, it has been suggested that an IELT of two minutes or less may serve as an adequately sensitive criterion for defining PE and some studies have used IELT values from one to two minutes for defining PE. In a pre-IND meeting with FDA, we agreed to use an IELT of less than or equal to 1 minute as one of the enrollment criteria for our planned Phase 3 clinical trials. The previous European Phase 3 trials allowed for an IELT of less than two minutes however a significant proportion of enrollees had an IELT of one minute or less. In our planned Phase 3 clinical trials, we will be utilizing the definition of lifelong PE adopted by the International Society for Sexual Medicine, or the ISSM: “premature ejaculation is a male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within a minute of vaginal penetration; and inability to delay ejaculation on all or nearly all vaginal penetrations; and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy.” As a result, we may encounter difficulty enrolling a sufficient number of patients in a timely fashion and we may not observe a similarly favorable safety and efficacy profile as our prior clinical trials.

In addition, Ampio obtained guidance from the FDA on our planned Phase 3 trials at a pre-IND meeting held in June 2012, including information to help us define the target patient population, select co-primary endpoints and design an acceptable patient-reported outcome measure. As a result of direction provided at the meeting, along with the existing data from six clinical trials of Zertane conducted outside the U.S. to date, we believe we are positioned to advance Zertane into Phase 3 clinical trials in the United States. However, we can provide no assurance that the FDA will not change its guidance about our planned Phase 3 clinical trials and require us to significantly modify the design of, or endpoints for, our planned clinical trials. Any change in the guidance we have received could delay and/or render more expensive our planned Phase 3 trial for Zertane.

We were not involved in any of the prior clinical studies for Zertane and are relying on the data collected from those prior clinical trials by various third parties, including a previous partner of our majority stockholder, Ampio Pharmaceuticals. Dr. David Bar-Or (now the Chief Scientific Officer of Ampio Pharmaceuticals) discovered the utility of tramadol hydrochloride for the treatment of PE in June 1999, and this discovery and accompanying intellectual property were at that time the property of DMI BioSciences, Inc., or DMI BioSciences. DMI BioSciences conducted various clinical trials, prior to licensing the worldwide rights to tramadol hydrochloride for PE to Biovail Laboratories International, or Biovail. Biovail also conducted several clinical trials and began two Phase 3 clinical trials, which trials were completed by Ampio upon its acquisition of DMI Biosciences, to whom the rights had reverted. This lack of prior involvement may have a negative impact on our understanding of these prior clinical trials and the design of our planned Phase 3 trial.

If we fail to successfully acquire new products, we may lose market position.

Acquiring new products will be an important factor in our sales growth, including products that already have been developed and found market acceptance. If we fail to identify existing or emerging consumer markets and trends and to acquire new products, we will not develop a strong revenue source to help pay for our development activities as well as possible acquisitions. This would delay our business plan, which could have a negative adverse effect on our business and prospects.

If we do not secure collaborations with strategic partners to test, commercialize and manufacture product candidates, we may not be able to successfully develop products and generate meaningful revenues.

A key aspect of our current strategy is to selectively enter into collaborations with third parties to conduct clinical testing, as well as to commercialize and manufacture product candidates. If we are able to identify and reach an agreement with one or more collaborators, our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. Collaboration agreements typically call for milestone payments that depend on successful demonstration of efficacy and safety, obtaining regulatory approvals, and clinical trial results. Collaboration revenues are not guaranteed, even when efficacy and safety are demonstrated. The current economic environment may result in potential collaborators electing to reduce their external spending, which may prevent us from developing our product candidates.

Even if we succeed in securing collaborators, the collaborators may fail to develop or effectively commercialize products using our product candidates. Collaborations involving our product candidates pose a number of risks, including the following:

As a result, collaboration agreements may not lead to development or commercialization of our product candidates in the most efficient manner or at all. For example, our former collaborator that licensed Zertane conducted clinical trials which we believe demonstrated efficacy in treating PE, but the collaborator undertook a merger that we believe altered its strategic focus and thereafter terminated the collaboration agreement. The Merger also created a potential conflict with a principal customer of the acquired company, which sells a product to treat premature ejaculation in certain European markets.

Collaboration agreements are generally terminable without cause on short notice. Once a collaboration agreement is signed, it may not lead to commercialization of a product candidate. We also face competition in seeking out collaborators. If we are unable to secure collaborations that achieve the collaborator’s objectives and meet our expectations, we may be unable to advance our product candidates and may not generate meaningful revenues.

We or our strategic partners may choose not to continue an existing product or choose not to develop a product candidate at any time during development, which would reduce or eliminate our potential return on investment for that product.

At any time and for any reason, we or our strategic partners may decide to discontinue the development or commercialization of a product or product candidate. If we terminate a program in which we have invested significant resources, we will reduce the return, or not receive any return, on our investment and we will have missed the opportunity to have allocated those resources to potentially more productive uses. If one of our strategic partners terminates a program, we will not receive any future milestone payments or royalties relating to that program under our agreement with that party.

Our product candidates are expected to undergo clinical trials that are time-consuming and expensive, the outcomes of which are unpredictable, and for which there is a high risk of failure. If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the FDA and other regulators, we or our collaborators may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of these product candidates.

Pre-clinical testing and clinical trials are long, expensive and unpredictable processes that can be subject to extensive delays. We cannot guarantee that any clinical studies will be conducted as planned or completed on schedule, if at all. It may take several years to complete the pre-clinical testing and clinical development necessary to commercialize a drug or biologic, and delays or failure can occur at any stage. Interim results of clinical trials do not necessarily predict final results, and success in pre-clinical testing and early clinical trials does not ensure that later clinical trials will be successful. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials even after promising results in earlier trials and we cannot be certain that we will not face similar setbacks. The design of a clinical trial can determine whether its results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. An unfavorable outcome in one or more trials would be a major set-back for that product candidate and for us. Due to our limited financial resources, an unfavorable outcome in one or more trials may require us to delay, reduce the scope of, or eliminate one or more product development programs, which could have a material adverse effect on our business, prospects and financial condition and on the value of our common stock.

In connection with clinical testing and trials, we face a number of risks, including:

The results of pre-clinical studies do not necessarily predict clinical success, and larger and later-stage clinical trials may not produce the same results as earlier-stage clinical trials. Frequently, product candidates developed by pharmaceutical companies have shown promising results in early pre-clinical studies or clinical trials, but have subsequently suffered significant setbacks or failed in later clinical trials. In addition, clinical trials of potential products often reveal that it is not possible or practical to continue development efforts for these product candidates.

If we do not successfully complete pre-clinical and clinical development, we will be unable to market and sell products derived from our product candidates and generate revenues. Even if we do successfully complete clinical trials, those results are not necessarily predictive of results of additional trials that may be needed before an NDA may be submitted to the FDA. Although there are a large number of drugs and biologics in development in the United States and other countries, only a small percentage result in the submission of an NDA to the FDA, even fewer are approved for commercialization, and only a small number achieve widespread physician and consumer acceptance following regulatory approval. If our clinical trials are substantially delayed or fail to prove the safety and effectiveness of our product candidates in development, we may not receive regulatory approval of any of these product candidates and our business, prospects and financial condition will be materially harmed.

Delays, suspensions and terminations in our clinical trials could result in increased costs to us and delay or prevent our ability to generate revenues.

Human clinical trials are very expensive, time-consuming, and difficult to design, implement and complete. We currently expect clinical trials of our therapeutic product candidates could take up to 24 months to complete, but the completion of trials for these candidates may be delayed for a variety of reasons, including delays in:

The commencement and completion of clinical trials for our product candidates may be delayed, suspended or terminated due to a number of factors, including:

Many of these factors may also ultimately lead to denial of an NDA for a product candidate. If we experience delay, suspensions or terminations in a clinical trial, the commercial prospects for the related product candidate will be harmed, and our ability to generate product revenues will be delayed.

In addition, we may encounter delays or product candidate rejections based on new governmental regulations, future legislative or administrative actions, or changes in FDA policy or interpretation during the period of product development. If we obtain required regulatory approvals, such approvals may later be withdrawn. Delays or failures in obtaining regulatory approvals may result in:

Furthermore, if we fail to comply with applicable FDA and other regulatory requirements at any stage during this regulatory process, we may encounter or be subject to:

We or our collaborators intend to seek FDA approval for some of our product candidates using an expedited process established by the FDA. If we, or our collaborators, are unable to secure clearances to use expedited development pathways from the FDA for certain of our drug product candidates, we, or they, may be required to conduct additional pre-clinical studies or clinical trials beyond those that we, or they, contemplate, which could increase the expense of obtaining, and delay the receipt of, necessary marketing approvals and of any product revenues.

Assuming successful completion of clinical trials, we expect to submit NDAs to the FDA at various times in the future under Section 505(b)(2) of the Food, Drug and Cosmetic Act, as amended, or the FDCA. NDAs submitted under this section are eligible to receive FDA approval by relying in part on the FDA’s findings of safety and efficacy for a previously approved drug. We specifically intend to do this for Zertane. The FDA’s 1999 guidance on Section 505(b)(2) applications states that new indications for a previously approved drug, a new combination product, a modified active ingredient, or changes in dosage form, strength, formulation, and route of administration of a previously approved product are encompassed within the Section 505(b)(2) NDA process. Relying on Section 505(b)(2) is advantageous because we or our collaborators may not be required (i) to perform the full range of safety and efficacy trials that is otherwise required to secure approval of a new drug, and (ii) obtain a “right of

reference” from the applicant that obtained approval of the previously approved drug. However, a Section 505(b)(2) application must support the proposed change of the previously approved drug by including necessary and adequate information, as determined by the FDA, and the FDA may still require us to perform a portion or the full range of safety and efficacy trials. There can be no assurance that we would be successful under any Section 505(b)(2) application.

The approval process outside the United States varies among countries and may limit our ability to develop, manufacture and sell our products internationally. Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.

In order to market and sell our products in the European Union and many other jurisdictions, we, and our collaborators, must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and may involve additional testing. We may conduct clinical trials for, and seek regulatory approval to market, our product candidates in countries other than the United States. Depending on the results of clinical trials and the process for obtaining regulatory approvals in other countries, we may decide to first seek regulatory approvals of a product candidate in countries other than the United States, or we may simultaneously seek regulatory approvals in the United States and other countries. If we or our collaborators seek marketing approval for a product candidate outside the United States, we will be subject to the regulatory requirements of health authorities in each country in which we seek approval. With respect to marketing authorizations in Europe, we will be required to submit a European Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA, which conducts a validation and scientific approval process in evaluating a product for safety and efficacy. The approval procedure varies among regions and countries and may involve additional testing, and the time required to obtain approval may differ from that required to obtain FDA approval.

Obtaining regulatory approvals from health authorities in countries outside the United States is likely to subject us to all of the risks associated with obtaining FDA approval described above. In addition, marketing approval by the FDA does not ensure approval by the health authorities of any other country, and approval by foreign health authorities does not ensure marketing approval by the FDA.

Even if we, or our collaborators, obtain marketing approvals for our product candidates, the terms of approvals and ongoing regulation of our products may limit how we or they market our products, which could materially impair our ability to generate revenue.

Even if we receive regulatory approval for a product candidate, this approval may carry conditions that limit the market for the product or put the product at a competitive disadvantage relative to alternative therapies. For instance, a regulatory approval may limit the indicated uses for which we can market a product or the patient population that may utilize the product, or may be required to carry a warning in its labeling and on its packaging. Products with boxed warnings are subject to more restrictive advertising regulations than products without such warnings. These restrictions could make it more difficult to market any product candidate effectively. Accordingly, assuming we, or our collaborators, receive marketing approval for one or more of our product candidates, we, and our collaborators expect to continue to expend time, money and effort in all areas of regulatory compliance.

Any of our products and product candidates for which we, or our collaborators, obtain marketing approval in the future could be subject to post-marketing restrictions or withdrawal from the market and we, and our collaborators, may be subject to substantial penalties if we, or they, fail to comply with regulatory requirements or if we, or they, experience unanticipated problems with our products following approval.

Any of our approved products and product candidates for which we, or our collaborators, obtain marketing approval, as well as the manufacturing processes, post-approval studies and measures, labeling, advertising and promotional activities for such products, among other things, are or will be subject to continual requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including the FDA requirement to implement a REMS to ensure that the benefits of a drug or biological product outweigh its risks.

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a product. The FDA and other agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed and distributed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we, or our collaborators, do not market any of our product candidates for which we, or they, receive marketing approval for only their approved indications, we, or they, may be subject to warnings or enforcement action for off-label marketing. Violation of the FDCA and other statutes, including the False Claims Act, relating to the promotion and advertising of prescription drugs may lead to investigations or allegations of violations of federal and state health care fraud and abuse laws and state consumer protection laws.

If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the commercialization of our product candidates may be delayed, and our business will be harmed.

We sometimes estimate for planning purposes the timing of the accomplishment of various scientific, clinical, regulatory and other product development objectives. These milestones may include our expectations regarding the commencement or completion of scientific studies and clinical trials, the submission of regulatory filings, or commercialization objectives. From time to time, we may publicly announce the expected timing of some of these milestones, such as the initiation or completion of an ongoing clinical trial, the initiation of other clinical programs, receipt of marketing approval, or a commercial launch of a product. The achievement of many of these milestones may be outside of our control. All of such milestones are based on a variety of assumptions which may cause the timing of achievement of the milestones to vary considerably from our estimates, including:

If we fail to achieve announced milestones in the timeframes we announce and expect, the commercialization of our product candidates may be delayed and our business, prospects and results of operations may be harmed.

We rely on third parties to conduct our clinical trials and perform data collection and analysis, which may result in costs and delays that prevent us from successfully commercializing product candidates.

We rely, and will rely in the future, on medical institutions, clinical investigators, contract research organizations, contract laboratories, and collaborators to perform data collection and analysis and others to carry out our clinical trials. Our development activities or clinical trials conducted in reliance on third parties may be delayed, suspended, or terminated if:

Third party performance failures may increase our development costs, delay our ability to obtain regulatory approval, and delay or prevent the commercialization of our product candidates. While we believe that there are numerous alternative sources to provide these services, in the event that we seek such alternative sources, we may not be able to enter into replacement arrangements without incurring delays or additional costs.

In addition, for Zertane, we are currently using, and relying on, single suppliers and single manufacturers for drug supply for our planned Phase 3 clinical trials and our commercial products. Although there are potential alternative suppliers and manufacturers for Zertane if need be, we have not qualified these vendors to date. If we were required to change vendors, it could result in a failure to meet regulatory requirements or projected timelines and necessary quality standards for successful manufacturing of the various required lots of material for our development and commercialization efforts, any of which could have an adverse effect on our business, prospects and financial condition.

Even if collaborators with which we contract in the future successfully complete clinical trials of our product candidates, those product candidates may not be commercialized successfully for other reasons.

Even if we contract with collaborators that successfully complete clinical trials for one or more of our product candidates, those candidates may not be commercialized for other reasons, including:

Relying on third-party manufacturers may result in delays in our clinical trials, product introductions and product supply.

Developing and commercializing new medicines and devices entails significant risks and expenses. Our clinical trials may be delayed if third-party manufacturers are unable to assure a sufficient quantity of the drug product to meet our study needs. If our clinical trials are delayed, our commercialization efforts may be impeded, or our costs may increase.

Once regulatory approval is obtained, a marketed product and its manufacturer are subject to continual review. The discovery of previously unknown problems with a product or manufacturer may result in restrictions on the product, manufacturer or manufacturing facility, including withdrawal of the product from the market. Any manufacturers with which we contract are required to operate in accordance with FDA-mandated current good manufacturing practices, or cGMPs. A failure of any of our contract manufacturers to establish and follow cGMPs and to document their adherence to such practices could lead to significant delays in the launch of our products candidates into the market or in the continued supply of any product after approval. Failure by third-party manufacturers to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, revocation or suspension of marketing approval for any products granted pre-market approvals, seizures or recalls of products, operating restrictions, and criminal prosecutions.

Further, if any manufacture needs to be replaced or new or increased product supplies obtained, we might not be able to locate and engage a new manufacturer on a timely basis or at all. Any of these events could have a material adverse effect on sales of an approved product, which could negatively impact our financial condition and our business.

We face substantial competition from companies with considerably more resources and experience than we have, which may result in others discovering, developing, receiving approval for, or commercializing products before or more successfully than us.

Many of our potential competitors have substantially greater financial, technical, personnel and marketing resources than we do. In addition, many of these competitors have significantly greater resources devoted to product development and pre-clinical research. Our ability to compete successfully will depend largely on our ability to:

Established pharmaceutical companies devote significant financial resources to discovering, developing or licensing novel compounds that could make our products and product candidates obsolete. Our competitors may obtain patent protection, receive FDA approval, and commercialize medicines before us. Other companies are or may become engaged in the discovery of compounds that may compete with the product candidates we are developing.

While no oral medication has been approved by the FDA for PE, Priligy (dapoxetine) has been approved in some countries. Many commonly prescribed oral medications may delay orgasm and be prescribed alone or in combination with other treatments. These medications include antidepressants, treatments for erectile dysfunction and tramadol for the treatment of pain. We also are aware of topical products which are over-the-counter, or OTC, monograph products for premature ejaculation which include brands such as Promescent (Absorption Pharmaceuticals), a topical spray approved by the FDA in 2013, EjectDelay (Innovus Pharma) and PreBoost (Aspen Park Pharmaceuticals), all of which would compete with Zertane.

For the RedoxSYS System and ProstaScint, we also compete with companies that design, manufacture and market already existing and new in-vitro diagnostics systems and tests.

We anticipate that we will face increased competition in the future as new companies enter the market with new technologies and our competitors improve their current products. One or more of our competitors may offer technology superior to ours and render our technology obsolete or uneconomical. Most of our current competitors, as well as many of our potential competitors, have greater name recognition, more substantial intellectual property portfolios, longer operating histories, significantly greater resources to invest in new technologies, more substantial experience in new product development, greater regulatory expertise, more extensive manufacturing capabilities and the distribution channels to deliver products to customers. If we are not able to compete successfully, we may not generate sufficient revenue to become profitable.

Any new product that competes with a currently-approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and/or safety in order to address price competition and be commercially successful. If we are not able to compete effectively against our current and future competitors, our business will not grow and our financial condition and operations will suffer.

Even if any of our product candidates are commercialized, they may not be accepted by physicians, patients, or the medical community in general.

Even if the medical community accepts a product as safe and efficacious for its indicated use, physicians may choose to restrict the use of the product if we or any collaborator is unable to demonstrate that, based on experience, clinical data, side-effect profiles and other factors, our product is preferable to any existing medicines or treatments. We cannot predict the degree of market acceptance of any product candidate that receives marketing approval, which will depend on a number of factors, including, but not limited to:

In the case of Zertane, tramadol hydrochloride is a well-established centrally acting synthetic analgesic that has been used for more than 30 years as a treatment for moderate to severe pain. As an opioid, tramadol hydrochloride has been associated with certain adverse effects including dizziness, nausea, constipation, vertigo, headache, vomiting and drowsiness. As a result, physicians may be reluctant to prescribe Zertane to treat premature ejaculation.

Zertane will, and our other product candidates may, contain controlled substances, the manufacture, use, sale, importation, exportation, prescribing and distribution of which are subject to regulation by the DEA.

Before we can commercialize Zertane, and potentially our other product candidates, the DEA will need to determine the controlled substance schedule, taking into account the recommendation of the FDA. This may be a lengthy process that could delay our marketing of a product candidate and could potentially diminish any regulatory exclusivity periods for which we may be eligible. Zertane will, and our other product candidates may, if approved, be regulated as “controlled substances” as defined in the Controlled Substances Act of 1970, or CSA, and the implementing regulations of the DEA, which establish registration, security, recordkeeping, reporting, storage, distribution, importation, exportation, inventory, quota and other requirements administered by the DEA. These requirements are applicable to us, to our third-party manufacturers and to distributors, prescribers and dispensers of our product candidates. The DEA regulates the handling of controlled substances through a closed chain of distribution. This control extends to the equipment and raw materials used in their manufacture and packaging, in order to prevent loss and diversion into illicit channels of commerce. A number of states and foreign countries also independently regulate these drugs as controlled substances.

The DEA regulates controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no established medicinal use, and may not be marketed or sold in the United States. A pharmaceutical product may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest relative risk of abuse among such substances.

We expect that Zertane will, and our other product candidates may, be listed by the DEA as Schedule IV controlled substances under the CSA. Consequently, the manufacturing, shipping, storing, selling and using of the products will be subject to a high degree of regulation. Also, distribution, prescribing and dispensing of these drugs are highly regulated.

Because of their restrictive nature, these laws and regulations could limit commercialization of our product candidates containing controlled substances. Failure to comply with these laws and regulations could also result in withdrawal of our DEA registrations, disruption in manufacturing and distribution activities, consent decrees, criminal and civil penalties and state actions, among other consequences.

Generic tramadol hydrochloride is available in the United States and abroad for treatment of pain. Although the generic drug is not available in the same dosage or formulation as Zertane for treatment of PE, it is possible that physicians could prescribe the generic version of the drug “off label” for the treatment of PE instead of Zertane, which would adversely affect our business.

Although Zertane is a specifically formulated, unique dosage of tramadol hydrochloride, generic tramadol hydrochloride is commercially available in the United States and abroad for treatment of pain. Although the generic drug is not available in the same dosage or form as Zertane for treatment of PE, it is possible that physicians could prescribe the generic version of the drug “off label” for the treatment of PE instead of Zertane, which would adversely affect our business. Patients could use generic tramadol hydrochloride dosages that are either higher or lower than what may be approved for Zertane or they could attempt to split dosages to arrive at reasonably similar dosages approved for Zertane. While any such “off label” use of generic tramadol hydrochloride for treatment of PE may constitute infringement of our patent portfolio, liability in that circumstance would be at the level of the physician or the patient making enforcement difficult or impractical.

Government restrictions on pricing and reimbursement, as well as other healthcare payor cost-containment initiatives, may negatively impact our ability to generate revenues if we obtain regulatory approval to market a product.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of health care costs to contain or reduce costs of health care may adversely affect one or more of the following:

The 2010 enactments of the Patient Protection and Affordable Care Act, or PPACA, and the Health Care and Education Reconciliation Act, or the Health Care Reconciliation Act, are expected to significantly impact the provision of, and payment for, health care in the United States. Various provisions of these laws have only recently taken effect or have yet to take effect, and are designed to expand Medicaid eligibility, subsidize insurance premiums, provide incentives for businesses to provide health care benefits, prohibit denials of coverage due to pre-existing conditions, establish health insurance exchanges, and provide additional support for medical research. Amendments to the PPACA and/or the Health Care Reconciliation Act, as well as new legislative proposals to reform healthcare and government insurance programs, along with the trend toward managed healthcare in the United States, could influence the purchase of medicines and medical devices and reduce demand and prices for our products and product candidates, if approved. This could harm our or our collaborators’ ability to market any products and generate revenues. Although we do not expect to receive significant revenues from reimbursement of our products by commercial third-party payors and government payors, cost containment measures that health care payors and providers are instituting and the effect of further health care reform could significantly reduce potential revenues from the sale of any of our products and product candidates approved in the future, and could cause an increase in our compliance, manufacturing, or other operating expenses. In addition, in certain foreign markets, the pricing of prescription drugs and devices is subject to government control and reimbursement may in some cases be unavailable. We believe that pricing pressures at the federal and state level, as well as internationally, will continue and may increase, which may make it difficult for us to sell any approved product at a price acceptable to us or any of our future collaborators.

In addition, in some foreign countries, the proposed pricing for a drug or medical c device must be approved before it may be lawfully marketed. The requirements governing pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. A member state may require that physicians prescribe the generic version of a drug instead of our approved branded product. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products or product candidates. Historically, pharmaceutical products launched in the European Union do not follow price structures of the United States and generally tend to have significantly lower prices.

Our products and product candidates may cause undesirable side effects that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. For example, adverse events associated with tramadol use in general and observed in the PE clinical trials included: gastrointestinal, or GI disorders (nausea) and central nervous system disorders (sleepiness, dizziness, headache) and decreased blood pressure.

Further, if a product candidate receives marketing approval and we or others identify undesirable side effects caused by the product after the approval, or if drug abuse is determined to be a significant problem with an approved product, a number of potentially significant negative consequences could result, including:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing an affected product or product candidates and significantly impact our ability to successfully commercialize or maintain sales of our product or product candidates and generate revenues.

ProstaScint may prove to be difficult to effectively commercialize following our acquisition of the product from Jazz Pharmaceuticals.

Various commercial, regulatory, and manufacturing factors may impact our ability to maintain or grow revenues following our acquisition of ProstaScint in May 2015. Specifically, we may encounter difficulty by virtue of:

We may use hazardous chemicals and biological materials in our business. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.

Our research and development processes may involve the controlled use of hazardous materials, including chemicals and biological materials. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, and our liability may exceed any insurance coverage and our total assets. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these hazardous materials and specified waste products, as well as the discharge of pollutants into the environment and human health and safety matters. Compliance with environmental laws and regulations may be expensive and may impair our research and development efforts. If we fail to comply with these requirements, we could incur substantial costs, including civil or criminal fines and penalties, clean-up costs or capital expenditures for control equipment or operational changes necessary to achieve and maintain compliance. In addition, we cannot predict the impact on our business of new or amended environmental laws or regulations or any changes in the way existing and future laws and regulations are interpreted and enforced.

The regulatory clearance or approval process is expensive, time consuming and uncertain, and the failure to obtain and maintain required clearances or approvals could prevent us from broadly commercializing the MiOXSYS System for clinical use.

The MiOXSYS System is subject to 510(k) clearance by the FDA prior to its marketing for commercial use in the United States, and to regulatory approvals required by foreign governmental entities prior to its marketing outside the United States. In addition, any changes or modifications to a device that has received regulatory clearance or approval that could significantly affect its safety or effectiveness, or would constitute a major change in its intended use, may require the submission of a new application for 510(k) clearance, pre-market approval, or foreign regulatory approvals. The 510(k) clearance and pre-market approval processes, as well as the process of obtaining foreign approvals, can be expensive, time consuming and uncertain. It generally takes from four to twelve months from submission to obtain 510(k) clearance, and from one to three years from submission to obtain pre-market approval; however, it may take longer, and 510(k) clearance or pre-market approval may never be obtained. We have limited experience in filing FDA applications for 510(k) clearance and pre-market approval. In addition, we are required to continue to comply with applicable FDA and other regulatory requirements even after obtaining clearance or approval. There can be no assurance that we will obtain or maintain any required clearance or approval on a timely basis, or at all. Any failure to obtain or any material delay in obtaining FDA clearance or any failure to maintain compliance with FDA regulatory requirements could harm our business, financial condition and results of operations.

Our financial results will depend on the acceptance among hospitals, third-party payors and the medical community of our products and product candidates.

Our future success depends on the acceptance by our target customers, third-party payors and the medical community that our products and product candidates are reliable, safe and cost-effective. Many factors may affect the market acceptance and commercial success of our products and product candidates, including:

If third-party payors do not reimburse our customers for the products we may sell or if reimbursement levels are set too low for us to sell one or more of our products at a profit, our ability to sell those products and our results of operations will be harmed.

While ProstaScint is already FDA-approved and generating revenues in the U.S., the product may not continue to receive physician, hospital, or laboratory acceptance, or it may not maintain adequate reimbursement from third party payors. Additionally, even if one of our product candidates is approved and reaches the market, the product may not achieve physician, hospital, or laboratory acceptance, or it may not obtain adequate reimbursement from third party payors. We expect to sell our products and product candidates to target customers substantially all of whom receive reimbursement for the health care services they provide to their patients from third-party payors, such as Medicare, Medicaid, other domestic and foreign government programs, private insurance plans and managed care programs. Reimbursement decisions by particular third-party payors depend upon a number of factors, including each third-party payor’s determination that use of a product is:

Third-party payors may deny reimbursement for covered products if they determine that a medical product was not used in accordance with cost-effective diagnosis methods, as determined by the third-party payor, or was used for an unapproved indication. Third-party payors also may refuse to reimburse for procedures and devices deemed to be experimental.

Obtaining coverage and reimbursement approval for a product from each government or third- party payor is a time consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of our potential product to each government or third-party payor. We may not be able to provide data sufficient to gain acceptance with respect to coverage and reimbursement. In addition, eligibility for coverage does not imply that any product will be covered and reimbursed in all cases or reimbursed at a rate that allows our potential customers to make a profit or even cover their costs.

Third-party payors are increasingly attempting to contain health care costs by limiting both coverage and the level of reimbursement for medical products and services. Levels of reimbursement may decrease in the future, and future legislation, regulation or reimbursement policies of third-party payors may adversely affect the demand for and reimbursement available for any product or product candidate, which in turn, could negatively impact pricing. If our customers are not adequately reimbursed for our products, they may reduce or discontinue purchases of our products, which would result in a significant shortfall in achieving revenue expectations and negatively impact our business, prospects and financial condition.

Manufacturing risks and inefficiencies may adversely affect our ability to produce our products.

As part of the acquisition of ProstaScint from Jazz Pharmaceuticals, we expect to resume the relationship with the third-party manufacturer of ProstaScint. We expect to transition the site of manufacture within the current manufacturer’s qualified sites. During this transition we may not be able to supply sufficient quantities and on a timely basis, while maintaining product quality, acceptable manufacturing costs and complying with regulatory requirements, such as quality system regulations. In addition, we expect to engage third parties to manufacture components of the RedoxSYS and MiOXSYS systems. For any future product, we expect to use third-party manufacturers because we do not have our own manufacturing capabilities. In determining the required quantities of any product and the manufacturing schedule, we must make significant judgments and estimates based on inventory levels, current market trends and other related factors. Because of the inherent nature of estimates and our limited experience in marketing any products, there could be significant differences between our estimates and the actual amounts of product we require. If we do not effectively transition sites with our manufacturing and development partners to enable to production scale of ProstaScint, or if we do not secure collaborations with manufacturing and development partners to enable production to scale of the RedoxSYS and MiOXSYS systems, we may not be successful in selling ProstaScint or in commercializing the RedoxSYS and MiOXSYS systems in the event we receive regulatory approval of the MiOXSYS System. If we fail in similar endeavors for future products, we may not be successful in establishing or continuing the commercialization of our products and product candidates.

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured these components ourselves, including:

Further, if we are unable to secure the needed financing to fund our internal operations, we may not have adequate resources required to effectively and rapidly transition our site of ProstaScint manufacture. We may not be able to meet the demand for the RedoxSYS System if one or more of any third-party manufacturers is not able to supply us with the necessary components that meet our specifications. It may be difficult to find alternate suppliers for any of our products or product candidates in a timely manner and on terms acceptable to us.

Any third-party manufacturers we engage are subject to various governmental regulations, and we may incur significant expenses to comply with, and experience delays in our product commercialization as a result of these regulations.

The manufacturing processes and facilities of third-party manufacturers we engage are required to comply with the federal Quality System Regulation, or QSR, which covers procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of devices. The FDA enforces the QSR through periodic unannounced inspections of manufacturing facilities. Any inspection by the FDA could lead to additional compliance requests that could cause delays in our product commercialization. Failure to comply with applicable FDA requirements, or later discovery of previously unknown problems with the manufacturing processes and facilities of third-party manufacturers we engage, including the failure to take satisfactory corrective actions in response to an adverse QSR inspection, can result in, among other things:

Any of these actions, in combination or alone, could prevent us from marketing, distributing or selling the RedoxSYS System or ProstaScint or any other approved product, and would likely harm our business.

In addition, a product defect or regulatory violation could lead to a government-mandated or voluntary recall by us. We believe the FDA would request that we initiate a voluntary recall if a product was defective or presented a risk of injury or gross deception. Regulatory agencies in other countries have similar authority to recall drugs or devices because of material deficiencies or defects in design or manufacture that could endanger health. Any recall would divert our management attention and financial resources, expose us to product liability or other claims, and harm our reputation with customers.

We have limited experience in sales and marketing and may be unable to successfully commercialize our products and product candidates.

As a company, we have limited marketing, sales and distribution experience and capabilities. Our ability to achieve profitability depends on attracting and retaining customers for our products and product candidates, and building brand loyalty. To successfully perform sales, marketing, distribution and customer support functions, we will face a number of risks, including:

In addition, we may seek to enlist one or more third parties to assist with sales, distribution and customer support globally or in certain regions of the world. If we do seek to enter into these arrangements, we may not be successful

in attracting desirable sales and distribution partners, or we may not be able to enter into these arrangements on favorable terms, or at all. If our sales and marketing efforts, or those of any third-party sales and distribution partners, are not successful, our currently approved products may not achieve increased market acceptance and our product candidates may not gain market acceptance, which would materially impact our business and operations.

We face intense competition from established and new companies in the in-vitro diagnostics field.

We compete with companies that design, manufacture and market already-existing and new in-vitro diagnostics systems and tests. We anticipate that we will face increased competition in the future as new companies enter the market with new technologies and our competitors improve their current products. One or more of our competitors may offer technology superior to ours and render our technology obsolete or uneconomical. Most of our current competitors, as well as many of our potential competitors, have greater name recognition, more substantial intellectual property portfolios, longer operating histories, significantly greater resources to invest in new technologies, more substantial experience in new product development, greater regulatory expertise, more extensive manufacturing capabilities and the distribution channels to deliver products to customers. If we are not able to compete successfully, we may not generate sufficient revenue to become profitable.

Our future growth depends, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.

Our future profitability will depend, in part, on our ability to commercialize our products and product candidates in foreign markets for which we intend to primarily rely on collaboration with third parties. If we commercialize our products or product candidates in foreign markets, we would be subject to additional risks and uncertainties, including:

Foreign sales of our products or product candidates could also be adversely affected by the imposition of governmental controls, political and economic instability, trade restrictions and changes in tariffs.

We are subject to various regulations pertaining to the marketing of our products.

We are subject to various federal and state laws pertaining to healthcare fraud and abuse, including prohibitions on the offer of payment or acceptance of kickbacks or other remuneration for the purchase of our products, including inducements to potential patients to request our products and services. Additionally, any product promotion educational activities, support of continuing medical education programs, and other interactions with health-care professionals must be conducted in a manner consistent with the FDA regulations and the Anti-Kickback Statute. The Anti-Kickback Statute prohibits persons or entities from knowingly and willfully soliciting, receiving, offering or providing remuneration, directly or indirectly, to induce either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment may be made under a federal healthcare program such as the Medicare and Medicaid programs. Violations of the Anti-Kickback Statute can also carry potential federal False Claims Act liability. Additionally, many states have adopted laws similar to the Anti-

Kickback Statute. Some of these state prohibitions apply to referral of patients for healthcare items or services reimbursed by any third-party payer, not only the Medicare and Medicaid programs, and do not contain identical safe harbors. These and any new regulations or requirements may be difficult and expensive for us to comply with, may adversely impact the marketing of our existing products or delay introduction of our product candidates, which may have a material adverse effect on our business, operating results and financial condition.

Our ability to compete may decline if we do not adequately protect our proprietary rights.

Our commercial success depends on obtaining and maintaining proprietary rights to our products and product candidates as well as successfully defending these rights against third-party challenges. We will only be able to protect our products and product candidates from unauthorized use by third parties to the extent that valid and enforceable patents, or effectively protected trade secrets, cover them. Our ability to obtain patent protection for our products and product candidates is uncertain due to a number of factors, including:

Even if we have or obtain patents covering our products and product candidates, we may still be barred from making, using and selling them because of the patent rights of others. Others may have filed, and in the future may file, patent applications covering products that are similar or identical to ours. There are many issued U.S. and foreign patents relating to chemical compounds, therapeutic products, diagnostic devices, and some of these relate to our products and product candidates. These could materially affect our ability to sell our products and develop our product candidates. Because patent applications can take many years to issue, there may be currently pending applications unknown to us that may later result in issued patents that our products and product candidates may infringe. These patent applications may have priority over patent applications filed by us.

Obtaining and maintaining a patent portfolio entails significant expense and resources. Part of the expense includes periodic maintenance fees, renewal fees, annuity fees, various other governmental fees on patents and/or applications due in several stages over the lifetime of patents and/or applications, as well as the cost associated with complying with numerous procedural provisions during the patent application process. We may or may not choose to pursue or maintain protection for particular inventions. In addition, there are situations in which failure to make certain payments or noncompliance with certain requirements in the patent process can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If we choose to forgo patent protection or allow a patent application or patent to lapse purposefully or inadvertently, our competitive position could suffer.

Legal actions to enforce our patent rights can be expensive and may involve the diversion of significant management time. In addition, these legal actions could be unsuccessful and could also result in the invalidation of our patents or a finding that they are unenforceable. We may or may not choose to pursue litigation or other actions against those that have infringed on our patents, or used them without authorization, due to the associated expense and time commitment of monitoring these activities. If we fail to protect or to enforce our intellectual property rights successfully, our competitive position could suffer, which could harm our business, prospects, financial condition and results of operations.

Pharmaceutical and medical device patents and patent applications involve highly complex legal and factual questions, which, if determined adversely to us, could negatively impact our patent position.

The patent positions of pharmaceutical and medical device companies can be highly uncertain and involve complex legal and factual questions. The interpretation and breadth of claims allowed in some patents covering pharmaceutical compositions may be uncertain and difficult to determine, and are often affected materially by the facts and circumstances that pertain to the patented compositions and the related patent claims. The standards of the United States Patent and Trademark Office, or USPTO, are sometimes uncertain and could change in the future. Consequently, the issuance and scope of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or circumvented. U.S. patents and patent applications may also be subject to interference proceedings, and U.S. patents may be subject to re-examination proceedings, post-grant review and/or inter partes review in the USPTO. Foreign patents may be subject to opposition or comparable proceedings in the corresponding foreign patent office, which could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such interference, re-examination, post-grant review, inter partes review and opposition proceedings may be costly. Accordingly, rights under any issued patents may not provide us with sufficient protection against competitive products or processes.

In addition, changes in or different interpretations of patent laws in the United States and foreign countries may permit others to use our discoveries or to develop and commercialize our technology and products and product candidates without providing any compensation to us, or may limit the number of patents or claims we can obtain. The laws of some countries do not protect intellectual property rights to the same extent as U.S. laws and those countries may lack adequate rules and procedures for defending our intellectual property rights.

If we fail to obtain and maintain patent protection and trade secret protection of our products and product candidates, we could lose our competitive advantage and competition we face would increase, reducing any potential revenues and adversely affecting our ability to attain or maintain profitability.

From time to time, the United States Supreme Court, other federal courts, the United States Congress or the USPTO may change the standards of patentability and any such changes could have a negative impact on our business.

In addition, the Leahy-Smith America Invents Act, or the America Invents Act, which was signed into law in 2011, includes a number of significant changes to U.S. patent law. These changes include a transition from a “first-to-invent” system to a “first-to-file” system, changes the way issued patents are challenged, and changes the way patent applications are disputed during the examination process. These changes may favor larger and more established companies that have greater resources to devote to patent application filing and prosecution. The USPTO has developed regulations and procedures to govern the full implementation of the America Invents Act, and many of the substantive changes to patent law associated with the America Invents Act, and, in particular, the first-to-file provisions, became effective on March 16, 2013. Substantive changes to patent law associated with the America Invents Act may affect our ability to obtain patents, and if obtained, to enforce or defend them. Accordingly, it is not clear what, if any, impact the America Invents Act will ultimately have on the cost of prosecuting our patent applications, our ability to obtain patents based on our discoveries and our ability to enforce or defend any patents that may issue from our patent applications, all of which could have a material adverse effect on our business.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to patent protection, because we operate in the highly technical field of discovery and development of therapies and medical devices, we rely in part on trade secret protection in order to protect our proprietary technology and processes. However, trade secrets are difficult to protect. We expect to enter into confidentiality and intellectual property assignment agreements with our employees, consultants, outside scientific and commercial collaborators, sponsored researchers, and other advisors. These agreements generally require that the other party keep confidential and not disclose to third parties all confidential information developed by the party or made known to the party by us during the course of the party’s relationship with us. These agreements also generally provide that inventions conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be honored and may not effectively assign intellectual property rights to us.

In addition to contractual measures, we try to protect the confidential nature of our proprietary information using physical and technological security measures. Such measures may not, for example, in the case of misappropriation of a trade secret by an employee or third party with authorized access, provide adequate protection for our proprietary information. Our security measures may not prevent an employee or consultant from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to protect our interests fully. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive, and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets. Trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. If any of our confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently developed by a competitor, our competitive position could be harmed.

We may not be able to enforce our intellectual property rights throughout the world.

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to pharmaceuticals and medical devices. This could make it difficult for us to stop the infringement of some of our patents, if obtained, or the misappropriation of our other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we will not have the benefit of patent protection in such countries.

Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our technology and the enforcement of intellectual property.

Third parties may assert ownership or commercial rights to inventions we develop.

Third parties may in the future make claims challenging the inventorship or ownership of our intellectual property. We have or expect to have written agreements with collaborators that provide for the ownership of intellectual property arising from our collaborations. These agreements provide that we must negotiate certain commercial rights with collaborators with respect to joint inventions or inventions made by our collaborators that arise from the results of the collaboration. In some instances, there may not be adequate written provisions to address clearly the resolution of intellectual property rights that may arise from a collaboration. If we cannot successfully negotiate sufficient ownership and commercial rights to the inventions that result from our use of a third-party collaborator’s materials where required, or if disputes otherwise arise with respect to the intellectual property developed with the use of a collaborator’s samples, we may be limited in our ability to capitalize on the market potential of these

inventions. In addition, we may face claims by third parties that our agreements with employees, contractors, or consultants obligating them to assign intellectual property to us are ineffective, or in conflict with prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to capture the commercial value of such inventions. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property, or may lose our exclusive rights in that intellectual property. Either outcome could have an adverse impact on our business.

Third parties may assert that our employees or consultants have wrongfully used or disclosed confidential information or misappropriated trade secrets.

We might employ individuals who were previously employed at universities or other biopharmaceutical or medical device companies, including our competitors or potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of a former employer or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

A dispute concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time consuming and costly, and an unfavorable outcome could harm our business.

There is significant litigation in the pharmaceutical and medical device industries regarding patent and other intellectual property rights. While we are not currently subject to any pending intellectual property litigation, and are not aware of any such threatened litigation, we may be exposed to future litigation by third parties based on claims that our products or product candidates infringe the intellectual property rights of others. If our development and commercialization activities are found to infringe any such patents, we may have to pay significant damages or seek licenses to such patents. A patentee could prevent us from using the patented drugs, compositions or devices. We may need to resort to litigation to enforce a patent issued to us, to protect our trade secrets, or to determine the scope and validity of third-party proprietary rights. From time to time, we may hire scientific personnel or consultants formerly employed by other companies involved in one or more areas similar to the activities conducted by us. Either we or these individuals may be subject to allegations of trade secret misappropriation or other similar claims as a result of prior affiliations. If we become involved in litigation, it could consume a substantial portion of our managerial and financial resources, regardless of whether we win or lose. We may not be able to afford the costs of litigation. Any adverse ruling or perception of an adverse ruling in defending ourselves against these claims could have a material adverse impact on our cash position and stock price. Any legal action against us or our collaborators could lead to:

Ampio controls us, including having the ability to control the election of our directors, and its interests may conflict with or differ from your interests as stockholders.

As of September 30, 2015, Ampio owned 81.5% of our outstanding common stock. If Ampio were to choose so, as a result of its stock ownership, Ampio may be able to influence our management and affairs and control all matters submitted to our stockholders for approval, including the election of directors and approval of any merger, consolidation, or sale of all or substantially all of our assets or other major corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change in control of our company and might affect the

market price of our common stock. This control may delay, deter or prevent acts that would be favored by our other stockholders, as the interests of Ampio may not always coincide with our interests or the interests of our other stockholders. For example, Ampio may seek to cause us to take courses of action that, in its judgment, could enhance its investment in us, but which might involve risks to our other stockholders or adversely affect us or our other stockholders.

We may be unable to achieve some or all of the benefits that we expect to achieve from our separation from Ampio.

As a stand-alone, independent public company, we believe that our business will benefit from, among other things, allowing our management to design and implement corporate policies and strategies that are based primarily on the characteristics of our business, allowing us to focus our financial resources wholly on our own operations and implement and maintain a capital structure designed to meet our own specific needs. However, as a result of our separation from Ampio in April 2015 there is a risk that we may be more susceptible to market fluctuations and other adverse events than we would have been if we were still a part of Ampio. We may not be able to achieve some or all of the benefits that we expect to achieve as a stand-alone healthcare company or such benefits may be delayed or may not occur at all. For example, there can be no assurance that analysts and investors will place a greater value on our company as a stand-alone healthcare company than on our business as a part of Ampio.

Our historical financial information as a business conducted by Ampio may not be representative of our results as an independent public company.

The historical financial information included or incorporated herein does not necessarily reflect what our financial position, operating results or cash flows would have been had we been an independent entity during the historical periods presented. The historical costs and expenses reflected in our financial statements include amounts for certain corporate functions historically provided by Ampio, including costs of finance and other administrative services, and income taxes. These expense allocations were developed on the basis of what we and Ampio considered to be reasonable prices for the utilization of services provided or the benefits received by us. The historical financial information in our audited financial statements may not be indicative of what our results of operations, financial position, changes in equity and cash flows would have been had we been a separate stand-alone entity during the periods presented or will be in the future. We have not made adjustments to reflect many significant changes that will occur in our cost structure, funding and operations as a result of our separation from Ampio, including changes in our employee base, changes in our tax structure, potential increased costs associated with reduced economies of scale and increased costs associated with being a publicly traded, stand-alone company, such as audit fees, directors and officers insurance costs and compliance costs, nor have we made offsetting adjustments to reflect the benefits of this offering, as these factors are presently difficult to quantify. These same risks will apply to the financial information of the ProstaScint business when it is included in our financial statements.

We may have received better terms from unaffiliated third parties than the terms we received in our agreements with Ampio.

The agreements related to our separation from Ampio, including the assignment and assumption agreement, services agreement and the other agreements, were negotiated in the context of our separation from Ampio while we were still part of Ampio and, accordingly, may not reflect terms that would have resulted from arm’s-length negotiations among unaffiliated third parties. The terms of the agreements we negotiated in the context of our separation related to, among other things, allocation of assets, liabilities, rights, indemnifications and other obligations among Ampio and us. We may have received better terms from third parties because third parties may have competed with each other to win our business. Our sole director is also a member of the Ampio board.

Our ability to operate our business effectively may suffer if we or Ampio terminate our services agreement, or if we are unable to establish on a cost-effective basis our own administrative and other support functions in order to operate as a stand-alone company after the expiration or termination of our services agreement with Ampio.

Prior to the Merger, we relied on administrative and other resources of Ampio to operate our business. We have entered into a services agreement to retain the ability for specified periods to use certain Ampio resources. We may elect to continue this agreement for an indefinite period of time. Any decision by us to terminate this agreement would be approved by disinterested members of our management and board of directors under our procedures regarding related party transactions. After the termination of this agreement, we would need to create our own administrative and other support systems or contract with third parties to replace Ampio’s services. These services

may not be provided at the same level, and we may not be able to obtain the same benefits that we received prior to the separation. These services may not be sufficient to meet our needs, and if our agreement with Ampio is terminated, we may not be able to replace these services at all or obtain these services at prices and on terms as favorable as we currently have with Ampio. Any failure or significant downtime in our own administrative systems or in Ampio’s administrative systems during the transitional period could result in unexpected costs, impact our results or prevent us from paying our suppliers or employees and performing other administrative services on a timely basis.

We acquired the businesses of Vyrix (Zertane) and Luoxis (the RedoxSYS and MiOXSYS systems) from Ampio in the Merger. In addition, Joshua Disbrow and Jarrett Disbrow held executive positions at Ampio and/or its subsidiaries prior to the Merger. Further, at September 30, 2015, Ampio owned approximately 81.5% of our outstanding common stock. As a result, negative developments, including negative publicity, at Ampio could be imputed to our company and have an adverse impact on our business and prospects, including our ability to raise capital or enter into collaborations, and on the price of our common stock.

Third parties may seek to hold us responsible for liabilities of Ampio that we did not assume in our agreements.

In connection with our separation from Ampio, Ampio has generally agreed to retain all liabilities that did not historically arise from our business. Third parties may seek to hold us responsible for Ampio’s retained liabilities. Under our agreements with Ampio, Ampio has agreed to indemnify us for claims and losses relating to these retained liabilities. However, if those liabilities are significant and we are ultimately liable for them, we cannot assure you that we will be able to recover the full amount of our losses from Ampio.

Any disputes that arise between us and Ampio with respect to our past and ongoing relationships could harm our business operations.

Disputes may arise between Ampio and us in a number of areas relating to our past and ongoing relationships, including:

We may not be able to resolve any potential conflicts, and even if we do, the resolution may be less favorable than if we were dealing with an unaffiliated party.

The agreements we have entered into with Ampio may be amended upon agreement between the parties. While we are controlled by Ampio, Ampio may be able to require us to agree to amendments to these agreements that may be less favorable to us than the original terms of the agreements.

Some of our management may have conflicts of interest because of their ownership of Ampio common stock, options to acquire Ampio common stock and positions with Ampio.

Our sole director and three of our executive officers own Ampio common stock and options to purchase Ampio common stock. In addition, our sole director is also the Chief Executive Officer and a director of Ampio and our Chief Financial Officer is also the Chief Financial Officer of Ampio. Ownership of Ampio common stock and options to purchase Ampio common stock by our director and officers and the presence of a director of Ampio on

our board of directors could create, or appear to create, conflicts of interest with respect to matters involving both us and Ampio. For example, corporate opportunities may arise that are applicable or complementary to both of our businesses and that each business would be free to pursue, such as the potential acquisition of a particular business or technology. However, we do not believe that Ampio intends to acquire businesses that are focused on urological disorders. We have not established at this time any procedural mechanisms to address actual or perceived conflicts of interest of these individuals and expect that our board of directors, in the exercise of its fiduciary duties, will determine how to address any actual or perceived conflicts of interest on a case-by-case basis. If any corporate opportunity arises and if our sole director or officers do not pursue it on our behalf, we may not become aware of, and may potentially lose, a significant business opportunity.

We will need to develop and expand our company, and we may encounter difficulties in managing this development and expansion, which could disrupt our operations.

As of September 30, 2015, we had 12 full-time employees, and in connection with being a public company, we expect to increase our number of employees and the scope of our operations. To manage our anticipated development and expansion, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Also, our management may need to divert a disproportionate amount of its attention away from its day-to-day activities and devote a substantial amount of time to managing these development activities. Due to our limited resources, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. This may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. The physical expansion of our operations may lead to significant costs and may divert financial resources from other projects, such as the planned expanded commercialization of our approved products and the development of our product candidates. If our management is unable to effectively manage our expected development and expansion, our expenses may increase more than expected, our ability to generate or increase our revenue could be reduced and we may not be able to implement our business strategy. Our future financial performance and our ability to expand the market for our approved products and develop our product candidates, if approved, and compete effectively will depend, in part, on our ability to effectively manage the future development and expansion of our company.

We depend on key personnel and attracting qualified management personnel and our business could be harmed if we lose personnel and cannot attract new personnel.

Our success depends to a significant degree upon the technical and management skills of our officers and key personnel, including in particular those of Joshua Disbrow, our Chief Executive Officer, and Jarrett Disbrow, our Chief Operating Officer. The loss of the services of any of these individuals would likely have a material adverse effect on us. Our success also will depend upon our ability to attract and retain additional qualified management, marketing, technical, and sales executives and personnel. We do not maintain key person life insurance for any of our officers or key personnel. The loss of any of our key executives, or the failure to attract, integrate, motivate, and retain additional key personnel could have a material adverse effect on our business.

We compete for such personnel against numerous companies, including larger, more established companies with significantly greater financial resources than we possess. There can be no assurance that we will be successful in attracting or retaining such personnel, and the failure to do so could have a material adverse effect on our business, prospects, financial condition, and results of operations.

Product liability and other lawsuits could divert our resources, result in substantial liabilities and reduce the commercial potential of our product candidates.

The risk that we may be sued on product liability claims is inherent in the development and commercialization of pharmaceutical and medical device products. Side effects of, or manufacturing defects in, products that we develop and commercialized could result in the deterioration of a patient’s condition, injury or even death. Once a product is approved for sale and commercialized, the likelihood of product liability lawsuits increases. Claims may be brought by individuals seeking relief for themselves or by individuals or groups seeking to represent a class. These lawsuits may divert our management from pursuing our business strategy and may be costly to defend. In addition, if we are held liable in any of these lawsuits, we may incur substantial liabilities and may be forced to limit or forgo further commercialization of the affected products.

We may be subject to legal or administrative proceedings and litigation other than product liability lawsuits which may be costly to defend and could materially harm our business, financial condition and operations.

Although we expect to maintain general liability, clinical trial liability and product liability insurance, this insurance may not fully cover potential liabilities. In addition, inability to obtain or maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product or other legal or administrative liability claims could prevent or inhibit the commercial production and sale of any of our products and product candidates that receive regulatory approval, which could adversely affect our business. Product liability claims could also harm our reputation, which may adversely affect our collaborators’ ability to commercialize our products successfully.

In order to satisfy our obligations as a public company, we may need to hire additional qualified accounting and financial personnel with appropriate public company experience in the event that we no longer utilize the finance and administrative functions of Ampio.

As a public company, we must establish and maintain effective disclosure and financial controls. We may need to hire additional accounting and financial personnel with appropriate public company experience and technical accounting knowledge, and it may be difficult to recruit and maintain such personnel. Even if we are able to hire appropriate personnel, our existing operating expenses and operations will be impacted by the direct costs of their employment and the indirect consequences related to the diversion of management resources from product development efforts.

Our internal computer systems, or those of our third-party contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our product development programs.

Despite the implementation of security measures, our internal computer systems and those of our third-party contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we do not believe that we have experienced any such system failure, accident, or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a loss of clinical trial data for our product candidates which could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in a loss of or damage to our data or applications or other data or applications relating to our technology or product candidates, or inappropriate disclosure of confidential or proprietary information, we could incur liabilities and the further development of our product candidates could be delayed.

We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

We may acquire additional businesses or products, form strategic alliances or create joint ventures with third parties that we believe will complement or augment our existing business. If we acquire businesses with promising markets or technologies, we may not be able to realize the benefit of acquiring such businesses if we are unable to successfully integrate them with our existing operations and company culture. We may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition that delay or prevent us from realizing their expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we will achieve the expected synergies to justify the transaction. These risks apply to our acquisition of ProstaScint in May 2015.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of June 30, 2015, we had federal net operating loss carryforwards of approximately $17.1 million. The available net operating losses, if not utilized to offset taxable income in future periods, will begin to expire in 2031 and will completely expire in 2034. Under the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations promulgated thereunder, including, without limitation, the consolidated income tax return regulations, various corporate changes could limit our ability to use our net operating loss carryforwards and other tax attributes (such as research tax credits) to offset our income. Were Ampio’s equity ownership interest in our Company to fall below 80% and we were to be deconsolidated from Ampio’s consolidated federal income tax group, certain of our net operating loss carryforwards may not be available to us and we would not be able to use them to offset our U.S. federal taxable income. In the event of such a deconsolidation, it is possible that certain other tax attributes and

benefits resulting from U.S. federal income tax consolidation may no longer be available to us. Our Company and Ampio do not have a tax sharing agreement that could mitigate the loss of net operating losses and other tax attributes resulting from a deconsolidation or our incurrence of liability for the taxes of other members of the consolidated group by reason of the joint and several liability of group members. In addition to the deconsolidation risk, an “ownership change” (generally a 50% change (by value) in equity ownership over a three-year period) under Section 382 of the Code could limit our ability to offset, post-change, our U.S. federal taxable income. Section 382 of the Code imposes an annual limitation on the amount of post-ownership change taxable income a corporation may offset with pre-ownership change net operating loss carryforwards and certain recognized built-in losses. Either the deconsolidation or the ownership change scenario could result in increased future tax liability to us.

There is not now, and there may never be, an active, liquid and orderly trading market for our common stock.

There is not now, nor has there been since our inception, any substantial trading activity in our common stock or a market for shares of our common stock, and an active trading market for our shares may never develop or be sustained. As a result, investors in our common stock must bear the economic risk of holding those shares for an indefinite period of time. Although our common stock is quoted on the OTCQB, an over-the-counter quotation system, trading of our common stock is extremely limited and sporadic and at very low volumes. We do not now, and may not in the future, meet the initial listing standards of any national securities exchange, and we presently anticipate that our common stock will continue to be quoted on the OTCQB or another over-the-counter quotation system in the foreseeable future. In those venues, our stockholders may find it difficult to obtain accurate quotations as to the market value of their shares of our common stock, and may find few buyers to purchase their stock and few market makers to support its price. As a result of these and other factors, you may be unable to resell your shares of our common stock at or above the price for which you purchased them, or at all. Further, an inactive market may also impair our ability to raise capital by selling additional equity in the future, and may impair our ability to enter into strategic partnerships or acquire companies or products by using shares of our common stock as consideration.

Our share price is volatile and may be influenced by numerous factors, some of which are beyond our control.

The trading price of our common stock is likely to be highly volatile, and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. In addition to the factors discussed in this “Risk Factors” section and elsewhere in this report, these factors include:

In addition, the stock market in general, and the stocks of small-cap healthcare, biotechnology and pharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. The realization of any of the above risks or any of a broad range of other risks, including those described in these “Risk Factors,” could have a dramatic and material adverse impact on the market price of our common stock.

FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our stock.

The Financial Industry Regulatory Authority, or FINRA, has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are applicable to us or our common stock, they may make it more difficult for broker-dealers to recommend that at least some of their customers buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect on the market for and price of our common stock.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and any trading volume could decline.

Any trading market for our common stock that may develop will depend in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts do not currently, and may never, publish research on us or our business. If no securities or industry analysts commence coverage of our company, the trading price for our stock would be negatively affected. If securities or industry analysts initiate coverage, and one or more of those analysts downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and any trading volume to decline.

We may have material liabilities that have not been discovered as a result of the Merger.

As a result of the Merger, the former business plan and management of Rosewind have been abandoned and replaced with the business and management team of Vyrix and Luoxis. Prior to the Merger, there were no relationships or other connections among the businesses or individuals associated with Rosewind and Vyrix and Luoxis. As a result, we may have material liabilities that have not been discovered as a result of the Merger. We could experience losses as a result of any such undisclosed liabilities that are discovered, which could materially harm our business, prospects and financial condition. Although the Merger Agreement contains customary representations and warranties from Rosewind concerning its assets, liabilities, financial condition and affairs, there may be limited or no recourse against Rosewind’s pre-Merger stockholders or principals in the event those representations prove to be untrue. As a result, our stockholders will bear some, or all, of the risks relating to any such unknown or undisclosed liabilities.

We may be exposed to additional risks as a result of “going public” by means of a merger transaction.

We may be exposed to additional risks because the business of Vyrix and Luoxis has become a public company through a “reverse merger” transaction. There has been increased focus by government agencies on transactions such as the Merger in recent years, and we may be subject to increased scrutiny by the SEC and other government agencies and holders of our securities as a result of the completion of that transaction. Additionally, our “going public” by means of a reverse merger transaction may make it more difficult for us to obtain coverage from securities analysts of major brokerage firms following the Merger because there may be little incentive to those brokerage firms to recommend the purchase of our common stock. The occurrence of any such event could cause our business or stock price to suffer.

Because we became public by means of a “reverse merger,” it may be more difficult to list on a national exchange such as the NASDAQ, NYSE or NYSE MKT.

It may be more difficult to list on a major exchange because we have conducted a reverse merger. In 2011, the SEC approved new rules of the three major U.S. listing markets that toughen the standards that companies going public through a reverse merger must meet to become listed on those exchanges. Under the rules, NASDAQ, NYSE and NYSE MKT impose more stringent listing requirements for companies that become public through a reverse merger. Specifically, the rules prohibit a reverse merger company from applying to list on either the NASDAQ, NYSE or NYSE MKT until:

It is possible for a reverse merger company to be exempt from these special requirements, but only if a listing is in connection with a substantial, firm commitment underwritten public offering.

We have a substantial number of shares of authorized but unissued capital stock, and if we issue additional shares of our capital stock in the future, our existing stockholders will be diluted.

Our Certificate of Incorporation authorize the issuance of up to 300,000,000 shares of our common stock and up to 50,000,000 shares of preferred stock with the rights, preferences and privileges that our Board of Directors may determine from time to time. As of September 30, 2015, we had 14,259,681 shares of our common stock issued and outstanding, which represents 4.75% of our total authorized shares. In addition to capital raising activities, which we expect to continue to pursue in order to raise the funding we will need in order to continue our operations, other possible business and financial uses for our authorized capital stock include, without limitation, future stock splits, acquiring other companies, businesses or products in exchange for shares of our capital stock, issuing shares of our capital stock to partners or other collaborators in connection with strategic alliances, attracting and retaining employees by the issuance of additional securities under our equity compensation plans, or other transactions and corporate purposes that our Board of Directors deems are in the best interest of our company. Additionally, shares of our capital stock could be used for anti-takeover purposes or to delay or prevent changes in control or our

management. Any future issuances of shares of our capital stock may not be made on favorable terms or at all, they may not enhance stockholder value, they may have rights, preferences and privileges that are superior to those of our common stock, and they may have an adverse effect on our business or the trading price of our common stock. The issuance of any additional shares of our common stock will reduce the book value per share and may contribute to a reduction in the market price of the outstanding shares of our common stock. Additionally, any such issuance will reduce the proportionate ownership and voting power of all of our current stockholders.

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales could occur, could cause our stock price to fall.

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market after the legal restrictions on resale discussed in this prospectus lapse or after those shares become registered for resale pursuant to an effective registration statement, the trading price of our common stock could decline. As of September 30, 2015, a total of 14,259,681 shares of our common stock were outstanding. Of those shares, only approximately 3.5% are currently freely tradable, without restriction, in the public market. We have registered for resale under the Securities Act an aggregate of 2,463,080 shares of our common stock held by persons who are not affiliates of Ampio and those shares are freely tradable (except for shares held by our affiliates) provided the holders comply with applicable prospectus delivery requirements, and any sales of those shares or any perception in the market that such sales may occur could cause the trading price of our common stock to decline. Additionally, as of September 30, 2015, an aggregate of 12,629,684 shares subject to lock-up agreements entered into in connection with the Merger became or will become freely tradable upon the phased expiration of the lock-up agreements on April 16, 2017 (3,910,133 shares), October 16, 2017 (2,906,517 shares), April 16, 2018 (2,906,517 shares) and October 16, 2018 (2,906,517 shares).

We also have outstanding convertible notes that we issued in July and August 2015, in the aggregate principal amount of approximately $5.2 million. The notes are convertible at any time in a noteholder’s discretion into that number of shares of our common stock equal in an amount equal to 120% of the number of shares of common stock calculated by dividing the then outstanding principal and accrued interest by $4.63. A holder of notes will be obligated to convert on the terms of our next public offering of our stock resulting in proceeds to us of at least $5,000,000 in gross proceeds (excluding indebtedness converted in such financing) prior to the maturity date of the notes, referred to as a Qualified Financing. The principal and accrued interest under the notes will automatically convert into a number of shares of such equity securities of our company sold in such financing equal to 120% of the principal and accrued interest under such note divided by the lesser of (i) the lowest price paid by an investor in such financing or (ii) $4.63. In the event that we sell equity securities to investors at any time while the notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such financing into a number of shares of our capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (a) the lowest cash price per share paid by purchasers of shares in such financing, or (b) $4.63. If these notes are converted, the shares of common stock issuable upon conversion could be sold. We are registering for resale under the Securities Act an aggregate of 1,484,282 shares of our common stock into which these convertible notes may convert, and upon the effectiveness of that registration those shares will be freely tradable without restriction. The perception of such issuance and sale could negatively impact the price of our common stock.

We also are registering for resale under the Securities Act all of the 11,626,068 shares of our common stock owned by Ampio, and upon the effectiveness of that registration those shares will be freely tradable without restriction. The perception of such sale could negatively impact the price of our common stock.

In addition, shares of common stock that are reserved for future issuance under our future equity incentive plans will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, Rule 144 and Rule 701 under the Securities Act, and any future registration of such shares under the Securities Act. If these additional shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plan or otherwise, could result in dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

We expect that significant additional capital will be needed in the future to continue our planned operations. To raise capital, we may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors in a prior transaction may be materially diluted by subsequent sales. Additionally, any such sales may result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to those of holders of our common stock. Further, any future sales of our common stock by us or resales of our common stock by our existing stockholders could cause the market price of our common stock to decline. Any future grants of options, warrants or other securities exercisable or convertible into our common stock, or the exercise or conversion of such shares, and any sales of such shares in the market, could have an adverse effect on the market price of our common stock.

Some provisions of our charter documents and applicable Delaware law may discourage an acquisition of us by others, even if the acquisition may be beneficial to some of our stockholders.

Provisions in our Certificate of Incorporation and Amended and Restated Bylaws, as well as certain provisions of Delaware law, could make it more difficult for a third-party to acquire us, even if doing so may benefit some of our stockholders. These provisions include:

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by the board of directors. This provision could have the effect of discouraging, delaying or preventing someone from acquiring us or merging with us, whether or not it is desired by or beneficial to our stockholders.

Any provision of our Certificate of Incorporation or Bylaws or of Delaware law that is applicable to us that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock in the event that a potentially beneficial acquisition is discouraged, and could also affect the price that some investors are willing to pay for our common stock.

The elimination of personal liability against our directors and officers under Delaware law and the existence of indemnification rights held by our directors, officers and employees may result in substantial expenses.

Our Certificate of Incorporation and our Bylaws eliminate the personal liability of our directors and officers to us and our stockholders for damages for breach of fiduciary duty as a director or officer to the extent permissible under Delaware law. Further, our Certificate of Incorporation and our Bylaws and individual indemnification agreements we intend to enter with each of our directors and executive officers provide that we are obligated to indemnify each of our directors or officers to the fullest extent authorized by the Delaware law and, subject to certain conditions, advance the expenses incurred by any director or officer in defending any action, suit or proceeding prior to its final disposition. Those indemnification obligations could expose us to substantial expenditures to cover the cost of settlement or damage awards against our directors or officers, which we may be unable to afford. Further, those provisions and resulting costs may discourage us or our stockholders from bringing a lawsuit against any of our current or former directors or officers for breaches of their fiduciary duties, even if such actions might otherwise benefit our stockholders.

We do not intend to pay cash dividends on our capital stock in the foreseeable future.

We have never declared or paid any dividends on our common stock and do not anticipate paying any dividends in the foreseeable future. Any future payment of cash dividends in the future would depend on our financial condition, contractual restrictions, solvency tests imposed by applicable corporate laws, results of operations, anticipated cash requirements and other factors and will be at the discretion of the our Board of Directors. Our stockholders should not expect that we will ever pay cash or other dividends on our outstanding capital stock.

Our common stock is subject to the “penny stock” rules of the SEC and the trading market in the securities is limited, which makes transactions in the stock cumbersome and may reduce the value of an investment in the stock.

The SEC has adopted Rule 15g-9 which establishes the definition of a “penny stock,” for the purposes relevant to us, as any equity security that has a market price of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require:

In order to approve a person’s account for transactions in penny stocks, the broker or dealer must:

The broker or dealer must also deliver, prior to any transaction in a penny stock, a disclosure schedule prescribed by the SEC relating to the penny stock market, which, in highlight form sets forth:

Generally, brokers may be less willing to execute transactions in securities subject to the “penny stock” rules. This may make it more difficult for investors to dispose of common stock and cause a decline in the market value of stock.

Disclosure also has to be made about the risks of investing in penny stocks in both public offerings and in secondary trading and about the commissions payable to both the broker-dealer and the registered representative, current quotations for the securities and the rights and remedies available to an investor in cases of fraud in penny stock transactions. Finally, monthly statements have to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks.

This prospectus, including the sections entitled “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business,” contains forward-looking statements that are based on our management’s belief and assumptions and on information currently available to our management. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. Forward-looking statements in this prospectus include, but are not limited to, statements about:

In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue” or the negative of these terms or other comparable terminology. These statements are only predictions. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, which are, in some cases, beyond our control and which could materially affect results. Factors that may cause actual results to differ materially from current expectations include, among other things, those listed under “Risk Factors” and elsewhere in this prospectus. If one or more of these risks or uncertainties occur, or if our underlying assumptions prove to be incorrect, actual events or results may vary significantly from those implied or projected by the forward-looking statements. No forward-looking statement is a guarantee of future performance. You should read this prospectus and the documents that we reference in this prospectus and have filed with the Securities and Exchange Commission as exhibits to this prospectus completely and with the understanding that our actual future results may be materially different from any future results expressed or implied by these forward-looking statements.

The forward-looking statements in this prospectus represent our views as of the date of this prospectus. We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law. You should therefore not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this prospectus.

The proceeds from the resale of the shares of common stock under this prospectus are solely for the accounts of the selling stockholders identified in this prospectus. We will not receive any proceeds from the sale of shares under this prospectus.

On October 22, 2015, the bid and asked price as reported on the OTCQB of our common stock were each $4.35. As of October 12, 2015, there were 126 holders of record of our common stock.

We have not paid any cash dividends on our common stock and our Board of Directors presently intends to continue a policy of retaining earnings, if any, for use in our operations. The declaration and payment of dividends in the future, of which there can be no assurance, will be determined by the Board of Directors in light of conditions then existing, including earnings, financial condition, capital requirements and other factors. Delaware law prohibits us from declaring dividends where, if after giving effect to the distribution of the dividend:

Except as set forth above, there are no restrictions that currently materially limit our ability to pay dividends or which we reasonably believe are likely to limit materially the future payment of dividends on common stock.

Our Board of Directors has the right to authorize the issuance of preferred stock, without further stockholder approval, the holders of which may have preferences over the holders of our common stock as to payment of dividends.

We are a specialty healthcare company concentrating on developing and commercializing products with an initial focus on urological indications and related conditions. We are focused primarily on the urological disorders market and specifically sexual dysfunction, urological cancers and male infertility.

Through a multi-step reverse triangular merger, on April 16, 2015, Vyrix Pharmaceuticals, Inc. (“Vyrix”) and Luoxis Diagnostics, Inc. (“Luoxis”) merged with and into our Company (herein referred to as the Merger) and we abandoned our pre-merger business plans to solely pursue the specialty healthcare market, including the business of Vyrix and Luoxis. On June 8, 2015, we reincorporated as a domestic Delaware corporation under Delaware General Corporate Law and changed our name from Rosewind Corporation to Aytu BioScience, Inc., and effected a reverse stock split in which each common stock holder received one share of common stock for each every 12.174 shares outstanding (herein referred to as the Reverse Stock Split). All share and per share amounts in this prospectus have been adjusted to reflect the effect of the Reverse Stock Split.

In May 2015, we entered into and closed on an asset purchase agreement with Jazz Pharmaceuticals, Inc., pursuant to which we purchased assets related to Jazz Pharmaceuticals’ product known as ProstaScint^® (capromab pendetide), including certain intellectual property and contracts, and the product approvals, inventory and work in progress (together, the “ProstaScint Business”), and assumed certain of Jazz Pharmaceuticals’ liabilities, including those related to product approvals and the sale and marketing of ProstaScint. The purchase price consists of the upfront payment of $1.0 million. We also agreed to pay an additional $500,000 payable within five days after transfer for the ProstaScint-related product inventory and $227,000 payable on September 30, 2015 (which represents a portion of certain FDA fees). We also will pay 8% on its net sales made after October 31, 2017, payable up to a maximum aggregate payment of an additional $2.5 million.

On October 5, 2015, we entered into and closed on an Asset Purchase Agreement with FSC Laboratories, Inc., or FSC. Pursuant to the agreement, we purchased assets related to FSC’s product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in progress and all marketing and sales assets and materials related solely to Primsol (together, the “Primsol Business”), and assumed certain of FSC’s liabilities, including those related to the sale and marketing of Primsol arising after the closing. We paid $500,000 at closing for the Primsol Business and we agreed to pay an additional $141,694 payable within five days after transfer of the Primsol-related product inventory. We also agreed to pay an additional (a) $500,000 payable no later than March 31, 2016, (b) $500,000 payable no later than June 30, 2016, and (c) $250,000 payable no later than September 30, 2016 (together, the “Installment Payments”), for a total purchase price of $1,891,694.

To date, we have financed operations through a combination of private and public debt and equity financings including the net proceeds from the private placement of stocks as well as a convertible note. Although it is difficult to predict our liquidity requirements, based upon our current operating plan, we believe we will have sufficient cash to meet our projected operating requirements for at least the next 12 months. See “Liquidity and Capital Resources.”

We have not received any significant revenues from the commercialization of our product candidates and do not expect to receive significant revenues from the commercialization of our product candidates in the near term. However, we have recognized limited revenue from ProstaScint sales. We have incurred accumulated net losses since our inception, and as of June 30, 2015, we had a deficit accumulated of $18.4 million. Our net loss $7.7 million for the year ended June 30, 2015 and $5.6 million for the year ended June 30, 2014.

These historical financial statements prior to April 16, 2015 include the financial statements of Vyrix from its inception in November 2013, combined with the carve-out financial statements related to the Vyrix Acquired Assets from March 23, 2011, the date Ampio originally acquired the Vyrix assets (the “Vyrix Acquired Assets”) through its merger with DMI BioSciences, Inc. (“BioSciences”) and the financial statements of Luoxis from its inception in January 2013, combined with the carve-out financial statements related to Luoxis.

The carve-out financial statements present the statements of financial position of Vyrix and Luoxis and the Vyrix Acquired Assets and the statement of operations and cash flows for purposes of presenting complete comparative stand-alone financial statements in accordance with Regulation S-X, Article 3, General Instructions to Financial Statements, and Staff Accounting Bulletin Topic 1-B1, Costs Reflected in Historical Financial Statements. Historically, financial statements have not been prepared for Vyrix and Luoxis, as they were not held in a separate legal entity. Although Vyrix and Luoxis have not been segregated as a separate legal entity, related revenues, direct costs and expenses, assets and liabilities have historically been segregated on Ampio’s books. In addition, we allocated corporate overhead costs based on a review of specific labor and other overhead expenses and a reasonable estimate of activities related to Vyrix and Luoxis. Allocated labor and other overhead totaled $264,000 in 2015 and

$253,000 in 2014. We also prepared a calculation of income tax expense and deferred income tax assets and liabilities on a “separate return” basis (see Note 4 – Income Taxes). These financial statements do not include a carve-out for cash as the operations have historically been funded by Ampio. The historical carve-out financial statements may not be indicative of the future results of Vyrix and Luoxis as a stand-alone entities.

“We”, “us” and “our” as referred to herein include Vyrix and Luoxis, collectively.

Our activities, being primarily research and development, have not generated significant revenue to date.

We consider all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of money market fund investments. Our investment policy is to preserve principal and maintain liquidity. We periodically monitor our positions with, and the credit quality of the financial institutions with which we invest. Periodically, throughout the year, we have maintained balances in excess of federally insured limits.

Payments received upon signing of license agreements are for the right to use the license and are deferred and amortized over the lesser of the license term or patent life of the licensed drug. Milestone payments relate to obtaining regulatory approval, cumulative sales targets, and other projected milestones recognized at the time the milestones are achieved. Royalties will be recognized as revenue when earned.

We recognize revenue from product and service sales when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured.

Fixed assets are recorded at cost and after being placed in service, are depreciated using the straight-line method over estimated useful lives.

In-process research and development (“IPRD”) relates to the Zertane product and clinical trial data acquired in connection with the 2011 acquisition of BioSciences. The $7,500,000 recorded was based on an independent, third party appraisal of the fair value of the assets acquired. IPRD is considered an indefinite-lived intangible asset and its fair value will be assessed annually and written down if impaired. Once the Zertane product obtains regulatory approval and commercial production begins, IPRD will be reclassified to an intangible that will be amortized over its estimated useful life. If we decided to abandon the Zertane product, the IPRD would be expensed.

Costs of establishing patents, consisting of legal and filing fees paid to third parties, are expensed as incurred. The fair value of the Zertane patents, determined by an independent third party appraisal, is $500,000. The Zertane patents were acquired in connection with the 2011 acquisition of BioSciences and the cost is being amortized over the remaining U.S. patent lives of approximately 11 years. The cost of the RedoxSYS/MiOXSYS patents was $380,000 and is being amortized over the remaining U.S. patent lives of approximately 15 years.

The preparation of financial statements in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include valuation allowances, stock-based compensation, warrant valuation, purchase price allocation, valuation of contingent consideration, sales returns and allowances, useful lives of fixed assets and assumptions in evaluating impairment of definite and indefinite lived assets. Actual results could differ from these estimates.

We are included in the consolidated tax returns of Ampio. Our taxes are computed and reported on a “separate return” basis for these financial statements. Deferred taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carry forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The amount of income taxes and related income tax positions taken would be subject to audits by federal and state tax authorities if we filed these taxes on a separate basis. We have adopted accounting guidance for uncertain tax positions which provides that in order to recognize an uncertain tax benefit, the taxpayer must be more likely than not of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more than 50% likely to be realized upon settlement with the taxing authority. We believe that we have no material uncertain tax positions. Our policy is to record a liability for the difference between the benefits that are both recognized and measured pursuant to the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification(“ASC”) 740-10, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 (“ASC 740-10”) and tax position taken or expected to be taken on the tax return. Then, to the extent that the assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. We report tax-related interest and penalties as a component of income tax expense. During the periods reported, our management has concluded that no significant tax position requires recognition under ASC 740-10.

We account for share based payments by recognizing compensation expense based upon the estimated fair value of the awards on the date of grant. We determine the estimated grant fair value using the Black-Scholes option pricing model and recognizes compensation costs ratably over the period of service using the graded method.

Research and development costs are expensed as incurred with expenses recorded in the respective periods.

The carrying amounts of financial instruments, including cash and cash equivalents, accounts payable and other current assets and other liabilities are carried at cost which approximates fair value due to the short maturity of these instruments.

Aytu routinely performs an annual evaluation of the recoverability of the carrying value of its long-lived assets to determine if facts and circumstances indicate that the carrying value of assets or intangible assets may be impaired and if any adjustment is warranted. Based on its evaluation as of June 30, 2015 and 2014, respectively, no impairment existed for long-lived assets.

In June 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-10, “Technical Corrections and Improvements”. The amendments represent changes to clarify the codification, correct unintended application of guidance, or make minor improvements to the codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost. In addition, some of the amendments will make the codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the codification. The amendments that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon issuance. We are evaluating the impact of ASU 2015-10 on its financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. We are evaluating the impact of ASU 2015-03 on its financial statements.

In January 2015, the FASB issued ASU 2015-01, “Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The purpose of this amendment is to eliminate the concept of extraordinary items. As a result, an entity will no longer be required to separately classify, present and disclose extraordinary events and transactions. The amendment is effective for annual reporting periods beginning after December 15, 2015 and subsequent interim periods with early application permitted. We are evaluating the impact the adoption of ASU 2015-01 will have on its financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact the adoption of ASU 2014-15 will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, “Revenue from Contracts with Customers”. The standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance will be effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted but not prior to the original public organization effective date of December 15, 2016. We are evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

Results of operations for the year ended June 30, 2015 (“2015”) and the year ended June 30, 2014 (“2014”) reflected losses of approximately $7,723,000 and $5,579,000, respectively.

We have not generated significant revenue in our operating history. The total revenue recognized during 2015 and 2014 was $262,000 and $59,000, respectively. Revenue is earned from the amortization of advanced payments received on our license agreements. In 2012, we received a payment of $500,000 for our license agreement of Zertane with a Korean pharmaceutical company. This payment was deferred and is being recognized over 10 years. In 2014, we received a payment of $250,000 for our license agreement of Zertane with a Canadian-based supplier. This payment was deferred and is being recognized over seven years.

The $176,000 product and service revenue recognized in 2015 represents sales of our ProstaScint product and the RedoxSYS System.

Research and development costs consist of clinical trials and sponsored research, labor, stock-based compensation, sponsored research – related party and consultants and other. These costs relate solely to research and development without an allocation of general and administrative expenses and are summarized as follows:

Research and development expenses decreased $636,000, or 15.7%, in 2015 over 2014. This was due primarily to decreased costs in clinical trial and sponsored research related to the Zertane trials. We expect research and development expenses to increase in 2016 as compared to the 2015 level due to ramping up the Zertane trials.

General and administrative expenses consist of personnel costs for employees in executive, business development and operational functions and director fees; stock-based compensation; patents and intellectual property; professional fees including legal, auditing and accounting; occupancy, travel and other including rent, governmental and regulatory compliance, insurance, investor/public relations and professional subscriptions. These costs are summarized as follows:

General and administrative costs increased $2,036,000, or 86.7%, in 2015 over 2014. The increase in professional fees, labor costs and stock-based compensation primarily relates to increased costs related to the Merger and associated SEC filings and legal expenses, professional staffing, bonuses earned and stock options granted as well as the continuing vesting of stock option awards granted in previous years. Occupancy, travel and other increased due to the additional travel to commercialize the RedoxSYS System. We expect general and administrative expenses to increase in 2016 due to the expected overall growth of our company.

During 2015, our operating activities used $6.6 million in cash. The use of cash was approximately $1,089,000 lower than the net loss due primarily to non-cash charges for stock-based compensation, depreciation and amortization, amortization of prepaid research and development related party, an increase in accounts payable and an increase in contingent consideration related to the ProstaScint asset purchase. Cash used in operating activities also included a $24,000 deferred tax benefit and $561,000 decrease in payable to Ampio.

During 2014, our operating activities used $5.5 million in cash. The use of cash was approximately $77,000 lower than the net loss due primarily to non-cash charges for stock-based compensation, depreciation and amortization and an increase in related party payable. Cash used in operating activities also included a $814,000 deferred tax benefit, a $497,000 increase in prepaid expenses and a $465,000 increase in research and development - related party.

During 2015, cash was used to acquire ProstaScint as well as deposits for office space.

Net cash provided by financing activities in 2015 was $12.4 million which reflects a $7.4 million loan from Ampio which was later converted to stock, $5 million stock subscription payment from Ampio, $27,000 paid out to Luoxis option holders pursuant to the Merger and $20,000 paid out for liabilities pursuant to the Merger.

Net cash provided by financing activities in 2014 was $5.2 million which reflects a $4.6 million loan from Ampio and $637,000 in contributions from Ampio.

Commitments and contingencies are described below and summarized by the following table as of June 30, 2015:

In June 2015, we entered into a 37 month operating lease. This lease has initial base rent is $2,900 a month, with total base rent over the term of the lease of approximately $112,000. We recognize rental expense of the facility on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent.

We entered into agreements with manufacturing companies to build its RedoxSYS and MiOXSYS systems. The current remaining commitment is $133,000.

In connection with the Zertane clinical trials and RedoxSYS/MiOXSYS research studies, the remaining commitment is $329,000.

We entered into a Sponsored Research Agreement with Trauma Research LLC (“TRLLC”), a related party, in June 2013. Under the terms of the Sponsored Research Agreement, TRLLC agreed to work collaboratively in advancing the RedoxSYS System diagnostic platform through research and development efforts. The Sponsored Research Agreement may be terminated without cause by either party on 30 days’ notice.

We are obligated to pay $500,000 for the ProstaScint-related product inventory upon the inventory transfer in July 2015.

In July 2015, we entered into agreements with Ampio whereby we agreed to pay Ampio $30,000 per month for shared overhead which includes costs related to the shared facility, corporate staff, and other miscellaneous overhead expenses. These agreements will be in effect until they are terminated in writing by both parties.

We have not generated significant revenue as our primary activities are focused on research and development, advancing our primary product candidates, and raising capital. As of June 30, 2015, we had cash and cash equivalents totaling $7.4 million available to fund our operations and $1.2 million in accounts payable. Based upon the Ampio commitment to fund our operations with another $5.0 million and the sale of convertible notes in July and August 2015, we believe we have adequate capital to continue operations through calendar year 2016 and into calendar year 2017. This projection is based on a number of assumptions that may prove to be wrong, and we could exhaust our available cash and cash equivalents earlier than presently anticipated. We intend to seek additional capital within the next 12 months to expand our clinical development activities for Zertane and RedoxSYS/MiOXSYS as well as building out a sales force for our ProstaScint product. In addition, we intend to evaluate the capital markets from time to time to determine when to raise additional capital in the form of equity, convertible debt or otherwise, depending on market conditions relative to our need for funds at such time, and we will seek to raise additional capital during the next 12 months at such time as we conclude that such capital is available on terms that we consider to be in the best interests of our company and our stockholders.

We have prepared a budget for 2015 which reflects cash requirements for fixed, on-going expenses such as payroll, legal and accounting, patents and overhead at an average cash burn rate of approximately $400,000 to $500,000 per month. Additional funds are planned for regulatory approvals, clinical trials, outsourced research and development and commercialization consulting. Accordingly, it will be necessary to raise additional capital and/or enter into licensing or collaboration agreements. At this time, we expect to satisfy our future cash needs through Ampio’s contributions to us and private or public sales of our securities or debt financings. We cannot be certain that financing will be available to us on acceptable terms, or at all. Over the last three years, volatility in the financial markets has adversely affected the market capitalizations of many bioscience companies and generally made equity and debt financing more difficult to obtain. This volatility, coupled with other factors, may limit our access to additional financing.

In October of 2015 we acquired the Primsol business for $1.9 million which will be paid out over a one year period and entered into a manufacturing agreement with Biovest to provide the active pharmaceutical ingredient for ProstaScint over a four year period at a total cost of $5.0 million of which $2.5 million is expected to be paid in fiscal 2016. We have updated our forecast for fiscal 2016 and 2017 as of October 12, 2015 and we still believe that we have adequate capital as of this date along with the $5.0 million that will be contributed by Ampio to continue our operations through calendar 2016 and into 2017.

As part of our plan to raise capital, during July and August 2015, we sold in a private placement convertible promissory notes with an aggregate principal amount of $5.2 million. The notes are our unsecured obligation. Unless earlier converted, the notes will mature 18 months from their respective dates of issuance which will be on January 22, February 11 and February 28, 2017, with an option to extend up to six months at our discretion (provided that in the event we exercise such extension option, the then applicable interest rate shall increase by 2% for such extension period). We do not have the right to prepay the notes prior to the maturity date. Interest will accrue on the notes in the following amounts: (i) 8% simple interest per annum for the first six months and (ii) 12% simple interest per annum thereafter if not converted during the first six months. If there has not been a registration statement on Form S-1 filed with the SEC for the registration of the shares of common stock underlying the notes by the expiration of the first six-month period then (a) the interest rate will increase to 14% for the remainder of the period in which the notes remain outstanding and (b) any notes held by officers and directors of our Company will be subordinated to the remaining notes. Interest will accrue, is payable with the principal upon maturity, conversion or acceleration of the notes and may be paid in kind or in cash, in our sole discretion. The notes are convertible at any time in a noteholder’s discretion into that number of shares of our common stock equal in an amount equal to 120% of the number of shares of common stock calculated by dividing the then outstanding principal and accrued interest by $4.63. A holder of notes will be obligated to convert on the terms of our next public offering of our stock resulting in proceeds to us of at least $5,000,000 in gross proceeds (excluding indebtedness converted in such financing) prior to the maturity date of the notes (a “Qualified Financing”). The principal and accrued interest under the notes will automatically convert into a number of shares of such equity securities of our Company sold in such financing equal to 120% of the principal and accrued interest under such note divided by the lesser of (i) the lowest price paid by an investor in such financing or (ii) $4.63. In the event that we sell equity securities to investors at any time while the notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such financing into a number of shares of our capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (i) the lowest cash price per share paid by purchasers of shares in such financing, or (ii) $4.63.

If we cannot raise adequate additional capital in the future when we require it, we will be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. We also may be required to relinquish greater or all rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. This may lead to impairment or other charges, which could materially affect our balance sheet and operating results.

We do not have off-balance sheet arrangements, financings, or other relationships with unconsolidated entities or other persons, also known as “variable interest entities.”

In general, we believe that our operating expenses can be negatively impacted by increases in the cost of clinical trials due to inflation and rising health care costs.

Effective on April 16, 2015 and with the approval of our Board of Directors, we dismissed HJ & Associates, LLC, or HJ, as our independent registered public accounting firm engaged to audit our financial statements.

The report issued by HJ dated November 26, 2014 relating to its audits of our balance sheets as of August 31, 2014 and 2013, and the related statements of operations, changes in stockholders’ equity (deficit) and cash flows for each of the fiscal years then ended, contained an explanatory paragraph stating that there was substantial doubt about our ability to continue as a going concern. Other than as disclosed above, such reports did not contain an adverse opinion or disclaimer of opinion and were not qualified as to uncertainty, audit scope or accounting principles.

Our decision to dismiss HJ is not the result of any disagreement between us and HJ on matters of accounting principles or practices, financial statement disclosure or auditing scope or procedures. During our two most recent fiscal years, there were no disagreements with HJ on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of HJ, would have caused HJ to make a reference to the subject matter of the disagreement in connection with its reports. Pursuant to the rules of the SEC applicable to smaller reporting companies, HJ was not required to provide an attestation as to the effectiveness of our internal control over financial reporting for any period since our inception.

Other than as disclosed above, there were no reportable events (as that term is defined in Item 304(a)(1)(v) of Regulation S-K) during our two most recent fiscal years. Our Board of Directors discussed the subject matter referred to above with HJ. We authorized HJ to respond fully and without limitation to all requests of our successor accountant concerning all matters related to the annual and interim periods audited and reviewed by HJ, including with respect to the subject matter of any reportable event.

We provided HJ with a copy of the above disclosures and requested that HJ furnish a letter addressed to the SEC stating whether or not it agrees with the above statements, and, if not, stating the respects in which it does not agree. A copy of the letter dated April 22, 2015, is filed as Exhibit 16.1 to our Current Report on Form 8-K filed on April 22, 2015.

Effective on April 16, 2015 and with the approval of our Board of Directors, we have engaged EKS&H LLLP, or EKS&H, as our new independent registered public accounting firm. EKS&H was engaged by Vyrix and Luoxis prior to the Merger to audit their financial statements for the years ended June 30, 2014 and 2013 and the related statements of operations, changes in stockholders’ equity and cash flows for each of the years then ended June 30, 2014 and 2013 which are included in this prospectus.

During our two most recent fiscal years and through the date of our engagement of EKS&H, neither we nor anyone on our behalf consulted with EKS&H regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to our financial statements, and no written report or oral advice was provided to us by EKS&H that was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K promulgated under the Securities Act and the related instructions) or a reportable event (as that term is defined in Item 304(a)(1)(v) of Regulation S-K) relating to our company.

We are a specialty healthcare company concentrating on developing and commercializing products with an initial focus on urological related conditions. We are focused primarily on the urological disorders market and specifically sexual dysfunction, urological cancers and male infertility. We are currently focused on commercializing our ProstaScint^® product, which we plan to launch through a focused commercial infrastructure in the U.S. while developing corporate relationships outside the U.S. to launch ProstaScint in major healthcare markets around the world. We acquired ProstaScint in May 2015 from Jazz Pharmaceuticals. ProstaScint, which is approved by the U.S. Food and Drug Administration, or FDA, is a marketed biologic imaging agent specifically indicated for the diagnostic staging of prostate cancer patients. We have launched the RedoxSYS^® oxidation-reduction potential system, or the RedoxSYS System, into the global research market and are developing numerous clinical applications for this potential first-in-class diagnostic device. Additionally, we have developed the MiOXSYS System as a diagnostic device for the detection of infertility in semen analysis. Further, we plan to enter Phase 3 clinical development for our lead therapeutic candidate, Zertane, which is being studied in premature ejaculation.

The premature ejaculation market in the U.S. and Europe is expected to reach over $1.3 billion in annual sales in 2015, representing an increase of 10.3% since 2010. According to recent published analyses, premature ejaculation, or PE, is a highly prevalent male sexual dysfunction affecting 20-30% of men worldwide. Based on internal market research and published reports, we believe that PE is up to 1.5-times more prevalent than erectile dysfunction, or ED. Currently, there are no FDA-approved prescription products in the United States to treat PE, and to our knowledge, only two other prescription products have been approved elsewhere in the world. Treatment options for PE have traditionally included antidepressant drugs prescribed “off label,” topical numbing medications, and cognitive behavior therapy or counseling, all of which have had limited effectiveness in treating the disorder. PE therefore represents an area of significant unmet medical need. In addition, approximately 32% of the more than 12,000 men with PE surveyed in a 2007 study published in European Urology also suffered from ED. Accordingly, we believe that a combination product candidate to treat both PE and ED represents another significant worldwide market opportunity for us.

By virtue of our recent acquisition of ProstaScint, we are now commercial stage and generating sales for this FDA-approved prostate cancer imaging agent. As prostate cancer is a condition commonly diagnosed and treated by urologists, ProstaScint complements our urology-focused product pipeline. Prostate cancer is the most common cancer among men in the United States, with an estimated 218,000 annual cases (as of 2010). Further, more than 1,800,000 men are alive with some history of prostate cancer, and over 30,000 U.S. men die each year from the disease. The effect of prostate cancer on healthcare economics is substantial, which makes the need for accurate disease staging critical for treatment and management strategies. The U.S. market for the diagnosis and screening of prostate cancer is expected to total $17.4 billion in 2017, a CAGR of 7.5%.

We are actively developing the global market for the RedoxSYS System across a range of applications. Specifically, we have begun commercializing the RedoxSYS System for research use through direct selling, distribution partners, and academic collaborators. Over the past 18 months, we have engaged in over 60 trials around the world whereby prominent researchers are implementing oxidation-reduction potential, or ORP, as a marker in both chronic and acute illnesses and disorders in both clinical research as well as basic science research.

Through our extensive network of researchers, the RedoxSYS System has demonstrated the potential to have broad clinical applications. Studies are now underway at a major U.S. university in the area of male infertility. As such, we developed the MiOXSYS System as a line extension to RedoxSYS to specifically assess oxidative stress in semen as a tool to assess male infertility. Male infertility is prevalent, underserved, and oxidative stress is widely implicated in its pathophysiology. As such, we expect to bolster our research focus in this area with the MiOXSYS System to complement our focus on urologic conditions. The global male infertility market is expected to grow to over $300 million by 2020 with a CAGR of nearly 5% from 2013 to 2020. Oxidative stress is broadly implicated in the pathophysiology of male infertility, yet very few diagnostic tools exist to effectively measure oxidative stress levels in men. However, antioxidants are widely available and recommended to infertile men. With the introduction of the MiOXSYS System, we believe for the first time there will be an easy and effective diagnostic tool to assess degree of oxidative stress and monitor patients’ responses to antioxidant therapy.

Our premature ejaculation product candidate, Zertane, is a specifically formulated orally disintegrating tablet, or ODT, of tramadol hydrochloride patented for the on-demand treatment of PE. Zertane is being developed utilizing a regulatory pathway pursuant to Section 505(b)(2) of the FDCA, as the active ingredient is already well characterized for the treatment of pain, and we are relying on the FDA’s finding of safety of tramadol hydrochloride to support its use in a new indication, PE, at a lower dose. If we receive marketing approval for Zertane, we believe it will be the first commercial product approved by the FDA for PE.

By virtue of significant development work performed by a previous partner of Ampio, Zertane has already been evaluated outside the United States in two Phase 1 clinical trials, two Phase 2 clinical trials and two Phase 3 clinical trials. The two Phase 1 safety trials were conducted to characterize the concentration of tramadol hydrochloride in plasma after oral administration of a single Zertane ODT (89 mg) in healthy volunteers. Two randomized, placebo-controlled, blinded Phase 2 clinical trials were conducted in a total of 102 patients. These trials evaluated doses of tramadol hydrochloride between 25 and 120 mg in male subjects with PE. Two placebo-controlled, randomized and double-blind Phase 3 clinical trials were conducted in Europe to investigate tramadol hydrochloride 62 mg and 89 mg ODT for the treatment of PE when taken as needed between two and eight hours before a sexual event. This development work has demonstrated a favorable safety and efficacy profile of Zertane in men with PE. Furthermore, the safety and pharmacology of the drug substance in Zertane, tramadol hydrochloride, is well characterized, which should eliminate the need for us to conduct additional pre-clinical studies and safety trials. Based on guidance received at a recent consultation meeting with the FDA, we believe we are well positioned to initiate a Phase 3 clinical program with Zertane in the United States. Specifically, we believe the meeting clarified specific aspects of the trial, including the primary efficacy endpoints and patient inclusion and exclusion criteria. The FDA agreed to review a draft study protocol in advance of us submitting our Investigational New Drug application, or IND. Upon completion of the program, if successful, we plan to submit a New Drug Application, or NDA, and subsequently market Zertane in the United States, if approved.

On May 20, 2015, we acquired ProstaScint^® from Jazz Pharmaceuticals. ProstaScint Kit, or capromab pendetide (ProstaScint), is a radio-labeled monoclonal antibody, which is a biologic product that targets a specific antigen. ProstaScint targets Prostate Specific Membrane Antigen (PSMA), a protein uniquely expressed by prostate tissue. A radioactive substance called Indium In 111 is attached to the proprietary, mouse-derived antibody. The radiolabeled antibody infused into the patient and is taken up by prostate cancer cells which can be detected and visualized with a special nuclear medicine scan (single-photon emission tomography, or SPECT). ProstaScint has been shown to be clinically effective in determining the course of treatment for a patient who has had a prostatectomy and/or has suspected metastasis (spread of the cancer cells beyond the prostate). Further, ProstaScint has demonstrated efficacy in patients classified as High Risk or with recurrent prostate cancer. ProstaScint has been approved by the FDA and Health Canada, and significant clinical data exist demonstrating the significant predictive value in prostate cancer staging.

According to the American Cancer Society prostate cancer is the most common cancer among men in the United States, with an estimated 218,000 annual cases (as of 2010). Further, more than 1,800,000 men are alive with some history of prostate cancer, and over 30,000 U.S. men die each year from the disease. The effect of prostate cancer on healthcare economics is substantial, which makes the need for accurate disease staging critical for treatment and management strategies. The U.S. market for the diagnosis and screening of prostate cancer is expected to total $17.4 billion in 2017, a CAGR of 7.5%. Importantly, ProstaScint is the only FDA-approved radiopharmaceutical (for use in radioimmunoscintigraphy) specifically indicated for prostate cancer screening and is specifically highlighted in the American Cancer Society practice guidelines for prostate cancer screening and staging. A radiopharmaceutical is a radioactive chemical or pharmaceutic preparation, labeled with a radionuclide in varying concentrations, which is used as a diagnostic or therapeutic agent. ProstaScint is labeled with the radionuclide indium in 111 and is used as an imaging agent utilizing SPECT (single-photon emission computed tomography) imaging. Radioimmunoscintography is an imaging procedure involving the administration of radioactively-labeled monoclonal antibodies to detect specific affected cells in a diagnostic procedure. Monoclonal antibodies are proteins specifically genetically engineered from a clone of a particular type of cell (a B cell) and programmed to enable a specific effect on a cellular target.

We completed the development of the RedoxSYS System during the two years preceding the Merger. In 2014, we received ISO 13485 certification, demonstrating our compliance with global quality standards in medical device manufacturing. This enabled the launch of the RedoxSYS System into the research market around the world. We also received a CE marking in Europe and Health Canada clearance to begin the market development of the RedoxSYS System as a clinical diagnostic in Europe, Canada, and elsewhere around the world where CE marking is recognized. We launched sales efforts into the research market in late 2014 and since that time have already placed the RedoxSYS System at a number of prominent research centers in the United States, Europe, and Israel. These research placements are depicted below.

We expect to leverage these research relationships and build numerous applications in areas where researchers are studying oxidative stress. Currently, there are no available research platforms that measure oxidation-reduction potential in biologic fluids (i.e., blood, plasma, serum, semen, seminal fluid, cerebrospinal fluid, tissue, and cells). While oxidative stress is commonly studied in research settings around the world (both academia and industry), the current assessment methods are incomplete, time consuming, and often impractical for assessing oxidative stress completely. To position the RedoxSYS System effectively in the research market, we have placed key personnel in the United States, Europe, and Asia to develop direct research business relationships as well as distribution networks. From these networks, we expect to realize initial product revenues for the RedoxSYS System for research applications in 2015.

As part of our strategy to develop future clinical applications of the RedoxSYS System, we have conducted initial studies in reproductive health. Male infertility is a significant medical condition in which oxidative stress is well known to play a substantial role. As such, we believe developing a specific instrument platform (called the MiOXSYS System) to assess oxidative stress levels in semen and seminal fluid represents a significant commercial opportunity. Oxidative stress is well established as a leading contributing factor to male infertility. Further, a significant proportion of male infertility remains unexplained in part because of the lack of standardized tests available to clinicians and researchers to assess oxidative stress in semen and plasma. This lack of standardization has resulted in poor implementation of semen and plasma analysis around the world.

We have conducted proof-of-concept studies in male infertility with the MiOXSYS System with a leading research center in the United States, which demonstrate that oxidation-reduction potential effectively measures oxidative stress levels in semen and seminal plasma. Semen analysis studies are routinely conducted to assess causes of infertility, so we expect clinicians and oxidative stress researchers to readily integrate the MiOXSYS System into routine clinical use. Additional studies are now underway to evaluate the MiOXSYS System’s performance in the detection of oxidative stress levels in semen in healthy and infertile males. Of the approximately $300 million male infertility market, the North American market and Asia Pacific market dominate due to prevalence, awareness of treatment, and availability of treatment resources. Thus, it is important that we have already begun to establish distribution relationships and direct access to major oxidative stress researchers and clinicians.

An attractive aspect of the reproductive health market relates to reimbursement as infertility treatments and the associated diagnostic tests are generally paid directly by patients. The current infertility treatments could cost in excess of $10,000 per treatment cycle, so the addition of a moderately priced oxidative stress test would consume nominal relative costs while providing specific, actionable information needed to improve the oxidative status of infertile patients. The current infertility treatments include antioxidant supplements and lifestyle modifications that lower oxidative stress (e.g., smoking cessation, exercise, dietary changes, etc.), so the measurements reported by the MiOXSYS System could effectively guide treatment in the infertile patients.

We have an extensive range of intellectual property across our two primary, near-term assets. We have patent protection in the United States and several other large markets worldwide for the oxidation-reduction potential products and product candidates. Further, we have patent protection in the United States and several other large markets worldwide for the use of tramadol hydrochloride to treat PE. We also have intellectual property specifically covering Zertane-ED, and methods of using Zertane-ED to treat comorbid PE and ED that has issued patents in several large markets worldwide and is pending in the United States.

Our lead therapeutic product candidate is Zertane, a Phase 3-ready oral product for the treatment of PE. Zertane is in advanced clinical studies, and we have already completed pivotal study-enabling studies in Europe that demonstrate favorable efficacy and safety in more than 600 patients with PE. We intend to initiate and complete Phase 3 clinical trials in order to submit an NDA to obtain FDA approval for Zertane.

We intend to maximize the value of Zertane in the United States via either securing a licensing arrangement or commercializing it ourselves. We also expect to seek collaboration agreements to commercialize Zertane in the rest of world, or ROW, markets. We already have such agreements in place to commercialize Zertane in South Korea and Brazil, Canada, the Republic of South Africa, certain countries in Sub-Saharan Africa, Colombia and Latin America which will – if approved – provide royalty and milestone-based revenue for us.

Because ProstaScint is already approved by the FDA, we expect to launch a commercial infrastructure in order to support increased sales and distribution of ProstaScint in the U.S. In addition to U.S. approval, ProstaScint has also been approved by Health Canada. ProstaScint fills an important medical need in the detection of a common illness facing a significant number of men in the U.S. and around the world. Prostate cancer is the most common cancer among men in the United States, with an estimated 218,000 annual cases (as of 2010). Further, more than 1,800,000 men are alive with some history of prostate cancer, and over 30,000 U.S. men die each year from the disease.

ProstaScint has several unique selling features that we believe will enable significant sales growth and regular use by healthcare providers diagnosing and treating prostate cancer. ProstaScint is the only imaging agent that specifically targets prostate cancer cells and demonstrates high sensitivity, specificity, and accuracy. In multiple clinical studies researchers have shown that when SPECT/CT scans were used in patients pre-treated with ProstaScint, ProstaScint imaging was highly sensitive in detecting prostate cancer and significantly predictive of 10-year biochemical disease free survival in prostate cancer patients (86.6% vs. 65.5%; p=0.0014). Additionally, the American Cancer Society specifically recognizes ProstaScint by name in current prostate cancer diagnosis guidelines.

Our lead diagnostic product candidate is the MiOXSYS System, which is currently being studied in clinical trials at a major U.S. academic center to evaluate its utility in measuring oxidative stress in infertile males. If successful, these clinical trials are expected to pave the way for our MiOXSYS System to enter the male infertility market around the world.

The RedoxSYS System is expected to be commercialized initially as a research tool, and pending the outcome of our clinical studies – oxidative stress as a key indicator of male infertility – be commercialized for additional indications, if approved. Internationally, we intend to commercialize the RedoxSYS System for multiple potential indications where oxidative stress is implicated, if approved. The United States will be our primary focus in terms of commercialization opportunities. However, we intend to leverage ROW opportunities to drive incremental revenue and adoption of our RedoxSYS System as well as to facilitate research to develop further redox-modulated application for our RedoxSYS System. We intend to utilize distribution partners in Europe, Asia, and elsewhere to launch and grow sales in both research and diagnostic applications. We have established research collaborations with over 20 leading academic centers around the world. Further, the RedoxSYS System has been used in numerous clinical studies supported by pharmaceutical companies. As oxidative stress is widely studied in both academic and industry settings, the research application of the RedoxSYS System spans a wide range of applications in clinical research, basic science research, and health and wellness research. We seek, either directly or through distributors, to commercialize the RedoxSYS System across a broad range of potential customers. To date, we have signed distribution agreements for the research market with four companies, including EuroBio in France, Una Health in the United Kingdom, THP Medical in Austria, and KYS Technologies in Taiwan. We expect to significantly expand our distribution network throughout 2015 to enable entry into major markets in Europe and Asia. We plan to commercialize directly in the United States. We expect these research collaborations will generate new findings and potential clinical applications for the RedoxSYS System. In turn, we believe this development of new data and publications will enable us to pursue adjunct conditions where oxidative stress is implicated.

In order to diversify our product portfolio and create more value, we intend to seek to acquire complementary products or product candidates to develop and/or commercialize including marketed assets. Initially, the focus will be on acquiring products or product candidates for urological conditions but we will opportunistically consider other products or product candidates based on their ability to create value and complement our focus. We plan to pursue product acquisitions, inclusive of therapeutics, diagnostics, and devices, which will be evaluated for their strategic fit and potential for near-term and/or accretive value to us. In May 2015, we acquired ProstaScint as part of this strategy.

Our lead therapeutic product candidate, Zertane, is a specifically formulated orally disintegrating tablet, or ODT, of tramadol hydrochloride patented for the on-demand treatment of PE. Zertane is being developed utilizing a regulatory pathway pursuant to Section 505(b)(2) of the FDCA, as the active ingredient is already well characterized for the treatment of pain, and we are relying on the FDA’s finding of safety of tramadol hydrochloride to support its use in a new indication, PE, at a lower dose. If we receive marketing approval for Zertane, we believe it will be the first commercial prescription product approved by the FDA for PE.

By virtue of significant development work performed by a previous partner of Ampio, Zertane has already been evaluated outside the United States in two Phase 1 clinical trials, two Phase 2 clinical trials and two Phase 3 clinical trials. This development work has demonstrated a favorable safety and efficacy profile of Zertane in men with PE and helped inform the design and endpoints of the Phase 3 clinical trials we will need to obtain FDA approval. Furthermore, the safety and pharmacology of the drug substance in Zertane, tramadol hydrochloride, is well characterized, which we believe will eliminate the need for us to conduct additional pre-clinical studies and safety trials. We believe we are well positioned to initiate Phase 3 clinical trials with Zertane in the United States. Upon completion of the trials, if successful, we plan to submit an NDA to the FDA and subsequently market Zertane in the United States, if approved.

Our strategy for Zertane is focused on the initiation and completion of the Phase 3 clinical program in the United States and the development of worldwide commercialization and marketing partnerships. We expect to finalize clinical development of Zertane, seek FDA marketing approval and – if approved—commercialize the product candidate in the United States either directly or via partnerships. We will seek partnerships to commercialize Zertane in rest of world, or ROW, markets. We already have partnerships in place to market Zertane in South Korea and Brazil, which could provide near-term revenue for us if, working with our partners, we are able to successfully obtain regulatory approval in those countries. In addition, we recently entered into an agreement with Endo Ventures Limited, which recently acquired Paladin Labs Inc., or Paladin, a leading Canadian specialty pharmaceutical company, to provide exclusive rights to market, sell and distribute Zertane in Canada, the Republic of South Africa, certain countries in Sub-Saharan Africa, Colombia and Latin America. We also intend to build awareness of PE in the United States with the intention of paving the way for successful product introduction and initiate pre-clinical work on Zertane-ED as a potential combination treatment for PE and ED. We expect to use a similar clinical and commercial approach for Zertane-ED and we have a clinical development collaboration in place with our South Korean partner for the combination product candidate when we elect to actively pursue its development.

Medical literature contains several one-dimensional and multi-dimensional operational definitions of PE. The Diagnostic and Statistical Manual of Mental Disorders defines PE as persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the person wishes it, with the disturbance causing marked distress or interpersonal difficulty. Alternately, the International Society for Sexual Medicine, or the ISSM, has adopted a new and evidence-based definition for lifelong PE: “premature ejaculation is a male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within a minute of vaginal penetration; and inability to delay ejaculation on all or nearly all vaginal penetrations; and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy.”

PE may be classified as lifelong (primary) or acquired (secondary). Lifelong PE is characterized by onset from the first sexual experience and remains a problem throughout life. Acquired PE is characterized by either a gradual or subtle onset, with ejaculation being considered normal before onset of PE. Time to ejaculation is short but not usually as fast as in lifelong (less than 1 minute in almost all encounters). We believe acquired PE and/or situational PE suggests a psychological cause and behavioral therapy and/or relationship counseling may be the most appropriate initial therapy. In contrast, we believe lifelong PE suggests a biogenic cause and pharmacologic treatment is the most appropriate initial therapy.

However, IELT is not the sole criteria used to diagnose PE. We believe diagnosis of PE should also include a subject’s perceived control over ejaculation, as well as distress and interpersonal difficulty due to the condition. The need to objectively assess and diagnose PE beyond IELT has led to the development of several questionnaires within the male sexual dysfunction medical community including the Premature Ejaculation Diagnostic Tool (PEDT), Premature Ejaculation Profile, or PEP, the Index of Premature Ejaculation (IPE), and the Male Sexual Health Questionnaire Ejaculatory Dysfunction (MSHQ-EjD). In collaboration with the FDA, Ampio has also developed a modified version of PEP known as the Patient Outcome for Premature Ejaculation, referred to as the POPE.

PE is a significant medical need in the United States and worldwide as it causes significant emotional distress for affected men and their partners. According to an article published in European Urology in 2010 and a survey published in the Journal of the American Medical Association (JAMA) in 1999, PE is a highly prevalent male sexual dysfunction affecting 20-30% of men worldwide. However, most prevalence data on PE is based on patient surveys,

which are inherently subjective, and therefore some of the men surveyed may not have PE as it is defined by the medical societies noted above. In a 2007 study published in European Urology, the incidence of PE was assessed via a web-based survey of 12,133 men ages 18-70 in the United States, Germany and Italy. In this survey, 2,754 or 22.7%, of the men reported that they suffer from PE. The vast majority (87.9%) of men with PE wished that they had more control over time to climax. Additionally, a majority (57.6%) of the men surveyed reported that they would seek medical treatment if they knew that a pill to control ejaculation were available. We believe men would also ask their doctor about treatment options if their partner suggested it. Additional primary company market research by a prominent pharmaceutical market research consulting firm commissioned by Ampio indicated that over 66% of patients that see a urologist for PE were self-referred, which we believe further demonstrates that PE is a condition for which patients are actively seeking treatment.

Presently, there are no approved prescription pharmaceuticals in the United States to treat PE and only two pharmaceuticals known to be approved elsewhere in the world. Current “off label” or unapproved therapies used to treat PE carry with them unwanted side effects and inconsistent or limited effectiveness. Topical over-the-counter, or OTC, options are not preferred due to route of administration and may also have an impact on partner satisfaction. Oral therapeutics, specifically selective serotonin reuptake inhibitors, or SSRIs, carry potentially significant side effects most notably of which is diminished libido. PDE-5 inhibitors have been prescribed “off label” for PE but have not demonstrated efficacy. Outside of oral or topical therapeutics, non-medical options include behavioral therapy and relationship counseling, both of which can be time consuming and stressful and frequently ineffective for men and their partners.

The following table illustrates the current methods used to treat patients with PE and the associated issues based upon our sponsored market research:

We believe patients and their partners are generally dissatisfied with existing pharmacologic and non-pharmacologic treatments for PE. Based on primary market research by a prominent pharmaceutical market research consulting firm commissioned by Ampio, which previously owned the rights to Zertane and is our largest stockholder, which included discussions with a cross section of clinicians that treat patients with PE, we believe that there are significant issues with existing PE treatments demonstrating a real need for a safe and effective, FDA-approved product to treat PE that does not have a ramp-up period. This primary market research supports that ideal product characteristics include:

Our lead therapeutic product candidate, Zertane for premature ejaculation, contains 89 mg tramadol hydrochloride in an orally dissolving tablet, or ODT. Tramadol hydrochloride is a well-established, centrally acting synthetic analgesic and has been used for more than 30 years as a treatment for moderate to severe pain. The drug and its active metabolite (M1, O-desmethyltramadol) act as an opiate agonist, apparently by selective activity at the µ-receptor. Although the mechanism by which tramadol hydrochloride delays ejaculation has not been identified, numerous laboratory studies have shown that tramadol hydrochloride also acts as an N-methyl-D-aspartate receptor antagonist, 5-hydroxytryptamine type 2C receptor antagonist, 5 nicotinic acetylcholine receptor antagonist, M1 and M3 muscarinic acetylcholine receptor antagonist, and a serotonin and norepinephrine modulator. It is possible that one or a combination of these effects leads to a delay in ejaculation. The relative contribution of tramadol hydrochloride versus its M1 metabolite to delay ejaculation is unknown. However, the metabolite is six times more potent than the parent drug in producing analgesia in animal models and 200 times more potent in µ-receptor binding. As a pain medication, tramadol hydrochloride has been associated with certain adverse effects including dizziness, nausea, constipation, vertigo, headache, vomiting and drowsiness. However, we intend that our labeling for Zertane, if regulatory approval is obtained, will suggest “as required” dosing before sexual intercourse and not to exceed one tablet per day. Based on previous clinical studies, we believe that limiting the dosing to no more than once per day will minimize any side effects.

As an alternative to antidepressant and anxiolytic medication, tramadol hydrochloride has been recognized as a potential therapy for treatment of PE, after an association was observed between its use and improvements in ejaculation latency time. The combination of completed clinical trials, primarily performed in Europe, planned clinical trials in the United States, and literature are intended to establish the safety and efficacy of Zertane in the treatment of the condition and standardize the dose and dosing regimen.

Dr. David Bar-Or discovered the utility of tramadol hydrochloride for the treatment of PE in June 1999, and this discovery and accompanying intellectual property were the property of DMI BioSciences, Inc., or DMI BioSciences. DMI BioSciences conducted two Phase 2 clinical studies in male subjects with PE using a pharmacy-compounded gelatin capsule preparation. A proof-of-concept Phase 2 study was initiated in March 2003, and final patient assessments were on July 7, 2003. A dose-ranging study Phase 2 study was initiated in September 2004 and final patient assessments were in October 2005. In 2007, DMI BioSciences licensed the worldwide rights to tramadol hydrochloride for PE to Biovail Laboratories International, or Biovail.

Biovail had previously entered into a product development and licensing agreement with Ethypharm S.A., or Ethypharm, in 2002, which had developed an ODT formulation of tramadol hydrochloride using its proprietary FLASHTAB technology. In this agreement, Biovail acquired the rights to develop and market Ethypharm’s tramadol hydrochloride ODT product for use in the management of pain. In March of 2004, Biovail submitted a Section 505(b)(2) NDA (US NDA 21,639) to FDA for market registration of tramadol hydrochloride ODT 50 mg (RYBIX) for the management of moderate to moderately severe pain, and this NDA was granted approval in May 2005.

Biovail decided not to launch the RYBIX 50 mg ODT product in the United States, and in 2009, signed an NDA agreement with Ethypharm pursuant to which Ethypharm acquired all the rights to RYBIX 50 mg ODT and Biovail acquired the rights to develop, manufacture and market a FLASHTAB ODT product containing tramadol hydrochloride for the symptomatic treatment of PE. In this agreement, Biovail assigned to Ethypharm all of Biovail’s rights, title and interest in and to the approved NDA for RYBIX, the regulatory documentation and product rights to enable Ethypharm to develop and market RYBIX in the United States for the management of pain. In addition, the agreement granted Biovail the right to reference and use all data, regulatory filings and regulatory communication, including the approved NDA for RYBIX, the product rights (including any information, data, know-how, formulas, assays, or intellectual property contained in the approved NDA) and any and all related regulatory documentation that would be relevant for the purposes of developing, manufacturing or marketing the tramadol hydrochloride ODT product for PE.

Using the newly acquired FLASHTAB technology and manufacturing processes obtained in the NDA agreement with Ethypharm, Biovail developed two strengths of tramadol hydrochloride ODT (62 and 89 mg) for use in four NDA-enabling clinical trials: two Phase 1 pharmacokinetic/bioavailability and two Phase 3 placebo-controlled pivotal trials. These trials were initiated in the latter half of 2009. In July 2010, Biovail terminated the clinical trials

in Europe as a direct result of a merger with Valeant Pharmaceuticals International, or Valeant, which was announced in June 2010 but was finalized in September 2010. Following the merger, Valeant adopted a new research and development model and began identifying product development programs that did not align with this new R&D model. In connection with this new R&D model, Valeant decided to terminate Biovail’s licensing agreement for tramadol hydrochloride for PE and also to terminate the ongoing Phase 3 studies. The Valeant model did not include compounds that had any regulatory or clinical risk (i.e., were still in development) and instead was focused solely on “commercially ready” products.

Biovail withdrew from its licensing agreement with DMI BioSciences and the worldwide rights to tramadol hydrochloride for PE reverted back to DMI BioSciences, which was acquired in March 2011 by Ampio. In December of 2011, the Ethypharm-Biovail NDA Agreement was transferred to Ampio in an asset purchase from Valeant, providing Ampio access to all data, regulatory filings and rights to develop, manufacture and market tramadol hydrochloride ODT for PE. Ampio completed clinical study reports for the European Phase 3 studies and submitted tramadol hydrochloride 89 mg ODT for marketing authorization in Australia.

In December 2013, Ampio spun out the assets and agreements associated with its sexual dysfunction treatment portfolio, including Zertane, to its then wholly-owned subsidiary Vyrix. We acquired Vyrix in April 2015.

Six European clinical trials have been completed with Zertane: two Phase 1 trials in healthy volunteers and two Phase 2 and two Phase 3 trials in men with lifelong PE. The two Phase 1 safety trials were conducted to characterize the concentration of tramadol hydrochloride in plasma after oral administration of a single Zertane ODT (89 mg) in healthy volunteers.

Two randomized, placebo-controlled, blinded Phase 2 clinical trials were conducted in a total of 102 patients. The first of these showed that a single 25-mg dose of conventionally formulated immediate release tramadol hydrochloride (i.e., immediate-release gelatin capsules) was safe, well-tolerated and prolonged time to ejaculation in some, but not all, patients. The second trial evaluated three higher doses of tramadol hydrochloride: 65 mg, 85 mg and 120 mg. In this trial, a clear dose response was seen for both efficacy and safety, leading DMI Biosciences to conclude that the optimal tramadol hydrochloride dose to treat PE was likely to be in the range 60-90 mg.

Two placebo-controlled, randomized and double-blind Phase 3 clinical trials were conducted in Europe to investigate tramadol hydrochloride 62 mg and 89 mg ODT for the treatment of PE when taken as needed between two and eight hours before a sexual event. A total of 677 patients were randomized in the trials and received either the 62 or 89 mg ODT or a matching placebo ODT. Our claim that Zertane was efficacious in the Phase 3 trials is based on at least one of the two doses resulting in statistically significant improvements in both IELT and PEP measures (i.e., co-primary endpoints) from baseline to the end of the trial. Using IELT in combination with a self-report questionnaire (e.g., PEP or POPE) has gained acceptance as meaningful measures of pharmacoactivity and efficacy in the scientific and regulatory communities. The results of the Phase 3 trials suggest that tramadol hydrochloride 89 mg ODT is consistently more effective as a treatment for PE than tramadol hydrochloride 62 mg ODT. In accordance with the definitions from the clinical trial protocols, only the tramadol hydrochloride 89 mg ODT dose satisfied the claim for effective treatment of PE in both Phase 3 trials.

In light of the estimated size of the U.S. market opportunity for Zertane, FDA approval is a critical value driver for us in the near term. We believe we are well positioned to quickly move into NDA-enabling Phase 3 clinical development in order to complete and submit our Section 505(b)(2) NDA for Zertane. Ampio met with the FDA in a pre-IND meeting on June 20, 2012 and we subsequently met with the FDA on October 23, 2014. As a result of these meetings, we have been able to define the number and key aspects of necessary trials to progress Zertane to an NDA that may be accepted for filing by the FDA; furthermore, the results from the European trials will inform the design, endpoints and inclusion criteria for the U.S. Phase 3 program as well as recommendations by FDA:

As in the Phase 3 trials conducted in Europe, co-primary endpoints will be used for determination of efficacy. Both improvement in IELT, which will be captured by the partner in a blinded diary, and PE-related frustration or bother, which will be assessed after each sexual intercourse attempt as well as at the final study visit by a single question in the POPE, will be evaluated as co-primary endpoints to determine efficacy.

We currently expect to file the IND for Zertane in the second half of 2015. We are prepared to commence our Phase 3 clinical program soon after the IND becomes effective because our supplies are already manufactured and packaged and only require appropriate clinical labeling of the product candidate. Importantly, our manufacturing process has already been validated at the site of commercial manufacture.

Beyond seeking U.S. NDA approval, we plan to leverage partnerships to gain approval and eventual marketing authorization for Zertane in several key markets around the world. We already have partnerships in place with Daewoong Pharmaceuticals Co., Ltd. in South Korea and FBM Industria Farmaceutica Ltda. in Brazil, thereby providing potential royalty and milestone-based revenue if, working with our partners, we are successfully able to obtain regulatory approval in those countries. In addition, our recent agreement with Paladin provides Paladin with exclusive rights to market, sell and distribute Zertane in Canada, the Republic of South Africa, certain countries in Sub-Saharan Africa, Colombia and Latin America. Before marketing any products in Brazil and South Korea, approval must be received from the Brazilian Health Surveillance Agency (Anvisa) and the Ministry of Food and Drug Safety (MFDS, previously the Korean Food and Drug Administration), respectively. We intend to leverage the expertise of our local collaborators in these jurisdictions to navigate the regulatory requirements and help determine an efficient and effective pathway to bringing Zertane to market. If required regulatory approvals are obtained, partnerships in ROW markets will potentially provide additional revenue to us and help to establish the Zertane brand and the role of tramadol hydrochloride in PE around the world. Such clinical experience will be useful as we seek to impact treatment guidelines for PE and gather post-marketing data to better inform our U.S. NDA submission.

Given the population and the anticipated pricing, the United States represents the largest PE opportunity and we will seek to maximize the market potential for Zertane in one or more of the following ways:

As stated previously, we intend to leverage partnerships to market Zertane around the world. We will seek to collaborate in the largest viable markets with companies that are well positioned to maximize sales of Zertane. Considerations for collaborations will include the prospective collaborator’s presence in the therapeutic category of men’s health, its ability to invest in the regulatory and commercialization activities necessary, and its commitment to Zertane, our management team and economic terms. Countries will be prioritized for partnering based on viability of Zertane in the market, including but not limited to regulatory pathway (i.e., the amount of regulatory work required for the partner to submit for approval); market conditions (markets that accept sexual health products); economic factors (pricing); and market size, as well as deal teams, including but not limited to royalty and/or milestone based economic terms; upfront payments based on market; and commitment to marketing and/or regulatory investments.

We already have entered into collaboration agreements in South Korea and Brazil, which represent two of the larger ROW market opportunities. In addition, our recent agreement with Paladin provides Paladin with exclusive rights to market, sell and distribute Zertane in Canada, the Republic of South Africa, certain countries in Sub-Saharan Africa, Colombia and Latin America. We will seek to enter into similar arrangements in additional countries with additional companies in order to capitalize on the sizable opportunity for Zertane, and later, Zertane-ED.

On May 20, 2015, we acquired ProstaScint^® from Jazz Pharmaceuticals. ProstaScint Kit, or capromab pendetide, is a radio-labeled monoclonal antibody, which is a biologic product that targets a specific antigen. ProstaScint targets Prostate Specific Membrane Antigen, or PSMA, a protein uniquely expressed by prostate tissue. A radioactive substance called Indium In 111 is attached to the proprietary, mouse-derived antibody. The radiolabeled antibody infused into the patient and is taken up by prostate cancer cells which can be detected and visualized with a special nuclear medicine scan (single-photon emission tomography, or SPECT). ProstaScint has been shown to be clinically effective in determining the course of treatment for a patient who has had a prostatectomy and/or has suspected metastasis (spread of the cancer cells beyond the prostate). Further, ProstaScint has demonstrated efficacy in patients classified as High Risk or with recurrent prostate cancer. ProstaScint has been approved by the FDA and Health Canada, and significant clinical data exist demonstrating the significant predictive value in prostate cancer staging.

Prostate cancer is classified into four stages based on severity: Stage 1 – 4. Stage 3 is considered “High Risk” and Stage 4 is when cancer has become metastatic. Radioimmunoscintigraphy has been established as diagnostic to stage cancer malignancy and one of the most widespread clinical uses has been for the detection of prostate cancer.

Multiple clinical studies have been conducted in the United States and published in peer-reviewed publications that consistently demonstrate substantial clinical efficacy of ProstaScint in staging prostate cancer patients and specifically identify whether the cancer is confined to the prostate or has metastasized to other parts of the body. Through more accurate clinical staging and identification of metastatic prostate cancer, clinicians are able to better direct therapeutic interventions and improve outcomes. A brief summary of key clinical findings for ProstaScint from select studies are summarized below.

Radiation oncology experts have published numerous papers expressing the potential for expanded use of ProstaScint in prostate cancer imaging due to advances in imaging technologies since the product’s initial approval. Since the early 2000s significantly greater image resolution has been enabled due to the advent of dual head cameras (and improved imaging in general) along with the use of co-registered images where radiologists now combine the images of SPECT and computerized tomography, or CT, or magnetic resonance imaging, or MRI. Because of these factors we believe there is significant commercial opportunity for ProstaScint.

ProstaScint is provided as a two-vial kit which contains all of the non-radioactive ingredients necessary to produce a single unit dose for administration by intravenous injection. The ProstaScint vial contains 0.5 mg of capromab pendetide in 1 mL of sodium phosphate buffered saline solution adjusted to pH 6; a sterile, pyrogen-free, clear, colorless solution that may contain some translucent particles. The vial of sodium acetate buffer contains 82 mg of sodium acetate in 2 mL of Water for Injection adjusted to pH 5-7 with glacial acetic acid; it is a sterile, pyrogen-free, clear, and colorless solution. Neither solution contains a preservative. Each kit also includes one sterile 0.22 ìm Millex^® GV filter, prescribing information, and two identification labels. It may also be helpful in conjunction with other scans (CT or MRI) for higher risk patients, by detecting lymph nodes in the abdomen that are involved with prostate cancer cells, but may still appear falsely normal on CT or MRI scans.

The procedure to administer ProstaScint is as follows: the patient is given an intravenous, or IV, infusion of the monoclonal antibody, and 30 minutes later, a scan is performed. A second scan is done between 96 and 120 hours (4-5 days) after the infusion. The first scan (on the day of the infusion) takes approximately 1 hour, while the second scan takes approximately 2.5 hours.

ProstaScint is indicated as a diagnostic imaging agent in newly-diagnosed patients with biopsy-proven prostate cancer, thought to be clinically-localized after standard diagnostic evaluation (e.g. chest x-ray, bone scan, CT scan, or MRI), who are at high-risk for pelvic lymph node metastases. It is not indicated in patients who are not at high risk.

ProstaScint is also indicated as a diagnostic imaging agent in post-prostatectomy patients with a rising PSA and a negative or equivocal standard metastatic evaluation in whom there is a high clinical suspicion of occult metastatic disease. The imaging performance of Indium In 111 ProstaScint following radiation therapy has not been studied.

The information provided by Indium In 111 ProstaScint imaging should be considered in conjunction with other diagnostic information. Scans that are positive for metastatic disease should be confirmed histologically in patients who are otherwise candidates for surgery or radiation therapy unless medically contraindicated. Scans that are negative for metastatic disease should not be used in lieu of histological confirmation. ProstaScint is not indicated as a screening tool for carcinoma of the prostate nor for re-administration for the purpose of assessment of response to treatment.

Our leading diagnostic product candidate, the RedoxSYS System, is now fully developed for research use. The RedoxSYS System was developed by Luoxis Diagnostics in the two years immediately preceding the Merger between Luoxis, Vyrix, and us in April 2015. Upon the consummation of the Merger, the RedoxSYS System became our asset. Prior to the incorporation of Luoxis, the predecessor technologies that are now incorporated into the RedoxSYS System were developed by the research team of Dr. David Bar-Or through a predecessor company, DMI BioSciences, Inc. that was acquired by Ampio.

The RedoxSYS System is a novel, portable device that measures oxidation-reduction potential, or ORP, a global measure of oxidative stress. The RedoxSYS System is the first and only system that measures ORP in biologic specimens to provide a complete measure of redox balance, which is broadly implicated across a wide range of both acute and chronic conditions. To date, Canadian and European regulators have characterized the RedoxSYS System as Class II medical device and regulated them accordingly. Classification of a medical device as Class II in Europe and Canada indicates that the device is generally regarded as posing medium risk, and non-invasive medical devices that come into contact with injured skin are generally classified as Class II. As we have conducted initial validation studies with the RedoxSYS System across a range of conditions and obtained a CE marking in Europe and Health Canada clearance to begin the market development of the RedoxSYS System as a clinical diagnostic in Europe, Canada, and elsewhere around the world where CE marking is recognized, we are now initiating commercialization for use of the RedoxSYS System as a research tool. By employing a focused commercial infrastructure and a growing network of distributors around the world, we believe we can efficiently penetrate the academic and industry-based research centers who study oxidative stress. With this growth in the research market, we intend to develop clinical applications for the RedoxSYS System.

An early potential opportunity that has presented promise through our research is the application of ORP in the study of male infertility. ORP represents a unique approach to assessing oxidative stress in male infertility, and early proof-of-concept studies have been conducted. We are now beginning clinical studies with a globally recognized U.S.-based university in male infertility. Oxidative stress is widely assessed in male infertility laboratories, and we believe the RedoxSYS System, if proven effective, will provide a simple, comprehensive solution to oxidative stress detection and management of antioxidant and lifestyle intervention in this underserved market. Given the preliminary results obtained from clinical trials conducted in semen analysis, we believe significant opportunity exists to launch a derivative product of RedoxSYS to specifically assess oxidative stress in the context of male infertility. Accordingly, we developed the MiOXSYS System as a uniquely designed and programmed device specific to the detection of oxidation-reduction potential in semen and seminal fluid.

Oxidative stress plays a pivotal role in the pathogenesis of male infertility. The presence of excess levels of reactive oxygen species, or ROS, is associated with both the structural and functional integrity of sperm. Moreover, these increased levels of ROS – the increase of oxidative stress – directly interfere with capacitation and fertilization. It is widely estimated that total infertility is driven by male infertility in half of the cases, and the major factors influencing the rise in infertility among men are the change in lifestyle, increasing age, and environmental effects.

Of all sexually active adults, 12-15% are infertile and male infertility is the sole cause or contributing factor 50% of the time. The global male infertility market is large and growing. The market is expected to grow to more than $300 million globally by 2020, with a CAGR of nearly 5% from 2013 to 2020. Despite the prevalence of male infertility, difficulties remain in effectively diagnosis root causes. Oxidative stress assessment is considered a standard practice but due to various factors is not effectively used routinely.

Oxidation-reduction potential is defined in the published literature as follows:

“ORP in a biological system is an integrated measure of the balance between total oxidants and reductants. In plasma, many constituents contribute to the ORP. Reactive oxygen species (ROS), such as the superoxide ion, hydroxyl radical, hydrogen peroxide, nitric oxide, peroxynitrite, transition metal ions, and hypochlorous acid, contribute to the oxidative potential. Plasma reductants include thiols, vitamin C, tocopherol, ß-carotene, lycopene, uric acid, bilirubin, and flavinoids. Enzymes such as superoxide dismutase, or SOD, catalase, and glutathione peroxidase, are involved in the conversion of ROS into less reactive species. ORP monitoring of plasma represents a single measurement that integrates the overall quantitative balance among the oxidants and reductants of the system.”

Given that ORP represents a single, global measure of oxidative stress in a biological system, we believe the potential for ORP to serve as a standardized marker in semen analysis and other aspects of infertility assessment is significant. A major limitation of oxidative stress assays relates to the fact that there is poor standardization in testing. As many factors contribute to oxidative stress (e.g., free radical proliferation, antioxidant depletion, DNA damage, etc.), it is important to have an integrated measure that combines all known and unknown oxidants and reductants in the respective system into one measurement. We believe ORP is an integrated measure of oxidative stress that can be easily and quickly measured with the RedoxSYS System.

In the context of infertility, having an integrated value representing all relevant biologic constituents contributing to oxidative stress will enable simple, robust analysis in a four-minute test.

There are various techniques in use to assess semen in cases of male infertility. The most commonly implemented techniques involve DNA fragmentation, oxidative stress analysis, microscopic examination, sperm penetration assays, sperm agglutination, computer assisted semen analysis, and others. The currently available oxidative stress analysis tools are widely considered expensive and cumbersome to use in routine clinical practice. In both developed countries as well as in the developing world, expensive analysis tools and recurring reagent expenses make routine testing nearly impossible to implement with regularity.

We believe the market opportunity for the RedoxSYS System is significant as scientists implicate oxidative stress in numerous diseases and acute conditions. Our initial focus of commercializing the RedoxSYS System for use in research enables us to rapidly build a base of clinical validation and utility data across a range of illnesses. As such, we expect to generate early revenues from oxidative stress researchers implementing the RedoxSYS System into their routine oxidative stress research programs while generating published clinical data demonstrating ORP’s usefulness in disease monitoring and prognostic assessment. From a clinical perspective, we plan to continue our research efforts in male infertility while expanding future applications in acute and chronic illnesses.

The global male infertility market is in excess of $300 million, while the broader in vitro diagnostics, or IVD, market is expected to grow to more than $80 billion by 2017. With a substantial base of conditions for which the MiOXSYS System may present utility, we expect to realize significant revenue potential from this first-in-class system.

Through our collaborative research efforts our scientific team has identified several diagnoses in which we believe the ORP technology derives distinct values that may be useful in better identifying a patient’s risk for the development of more severe illness – beyond reproductive health and infertility. Further, we believe the ORP technology has the potential to better stratify patients according to clinical characteristics detected uniquely by ORP measurements. Specific diseases where the RedoxSYS System has been initially studied include trauma, critical illness, stroke, heart failure, diabetes, and pregnancy. Multiple other clinical areas exist where the system could be studied and potentially applied.

Diagnostics serve a key role in the health value chain by influencing the quality of patient care, health outcomes and downstream resource requirements across a wide range of clinical conditions. From consumer-friendly at-home pregnancy and glucose monitoring tests to more complex automated laboratory-based systems, these tests are often first-line health decision tools. While diagnostics comprise less than 5% of hospital costs and about 1.6% of all Medicare costs, their findings are commonly believed to influence as much as 60-70% of health care decision-making. The value of diagnostics accrues not only to clinicians and patients, but to health care managers, third-party payors and quality assurance organizations that use diagnostic performance to measure and improve health care quality.

ORP is a tightly controlled measurement, much like the vital signs routinely measured in medical practice—temperature, heart rate, respiratory rate, blood pressure and oxygen saturation of blood. Abnormal changes in oxidation-reduction potential are closely associated with poor outcomes in critically ill patients, including traumatic brain injury, multi-trauma injury, stroke, sepsis, and pneumonia. Rapid results are essential for optimal treatment adjustments in critical care areas such as emergency and intensive care departments.

ORP results may also help determine which patients are at high risk of early readmission at hospital discharge, especially patients with heart attack, heart failure, stroke, and pneumonia, and this represents an incremental assessment not afforded by currently available diagnostic tests.

Numerous scientific studies confirm the clinical value of measuring oxidative stress. Recently, a large assortment of blood and cell tests have been used in research studies to measure separate biomarkers of oxidative stress, such as lipid peroxidation, protein oxidation and total antioxidants, but currently many of these separate biomarker test results are needed to start to assess total oxidative stress. Despite the importance of assessing oxidative stress, we are not aware of any practical or efficient method for measuring these oxidative stress biomarkers in a point-of-care setting. Oxidative stress is often a marker for inflammation, which in turn indicates the presence of disease-related processes or developing conditions across a wide array of diseases.

The worldwide IVD market was $44 billion in 2010 and is projected to grow to $82 billion by 2017. The IVD market includes all laboratory and hospital-based sales and home-use, or over-the counter, product sales covering immunoassays, clinical chemistry, microbiology, hematology, histology/cytology, point-of-care testing, and over-the-counter diagnostics. The professional point-of-care testing worldwide market is a significant opportunity and was in excess of $5 billion in 2009 and is expected to grow to almost $7 billion by 2014.

Importantly, critical care (an application for which the RedoxSYS System is targeted) constituted 14% ($700 million) of sales in 2009 with expected CAGR of 5%, and cardiac markers constituted 9% ($435 million) of sales in 2009 with expected CAGR of 8%.

We believe the RedoxSYS System is the first and only research and clinical diagnostic platform that provides an accurate, easy, and complete real-time assessment of redox status. Through the development and commercialization of the RedoxSYS System, we are pioneering the true measurement of redox potential, also called oxidation-reduction potential, a novel measure of oxidative stress, which has been implicated in numerous critical injuries, illnesses, and chronic conditions with significant appreciation of the role of oxidative stress in infertility. We believe the RedoxSYS platform has a broad range of potential in both research and clinical settings where no other methods exist to measure oxidation-reduction potential in biologic specimens.

Through research directed by Dr. David Bar-Or and Raphael Bar-Or at Ampio, we believe we have developed the first and only clinical diagnostic device that measures ORP in biologic specimens (i.e., plasma, serum, semen, seminal plasma, cells, tissues, cell cultures, and others). This device, called the RedoxSYS System, rapidly measures ORP and antioxidant capacity, a global marker of antioxidant reserve and concentration to provide a global picture of oxidative status. The system uses a small, bench top analyzer in conjunction with small, disposable sensors that work electrochemically without any liquid reagents or difficult sample preparation. The RedoxSYS System has been CE marked and approved for use in Europe and Canada, and we are now collaborating with major medical centers around the world for its use in research. The RedoxSYS System is an easy-to-use diagnostic device that can be used

in various research settings. Further, this portable device can be decentralized to multiple research sites and enable real-time reporting of oxidative stress values at the patient’s point of care or in a clinical laboratory setting. We received ISO 13485:2003 medical device certification in 2014.

The RedoxSYS System has been developed over an 18-year period by Dr. David Bar-Or, Raphael Bar-Or, and their colleagues, and the research and development work has focused on both the technical and clinical development of various applications.

The RedoxSYS System is comprised of two distinct, patented components that enable a system capable of measuring the ORP and antioxidant capacity of a biological fluid: an analyzer and sensor strips. In mechanical terms, ORP is defined as the potential between a working electrode and a reference electrode at equilibrium. The RedoxSYS System has been specifically studied in human whole blood, serum, plasma, semen, and other biological fluids. The RedoxSYS System measures two distinct elements to determine a patient’s oxidation reduction potential:

The RedoxSYS analyzer is a portable, lightweight desktop platform that may be used in a clinical or research laboratory or near a patient care area. The analyzer is a small device that accepts an inserted sensor that has collected a small specimen as obtained by traditional specimen collection procedures. The analyzer is battery powered and equipped with a custom 5 lead strip connector. The reader consists of a Galvanostat analog circuit with greater than 1012 MHz input impedance.

The analyzer contains a 10 MHz external crystal (internal 4X PLL for 40 MHz operation), and a programming/serial header is externally accessible. The device has internal power/heart-beat indicator LED, primary storage of 128Mbit (16Mbyte) SPI Flash (3.3V) (Bulk data storage), and secondary storage of 2Mbit (256Kbyte) SPI FRAM (3.3V) (Hi-Speed Storage).

The RedoxSYS analyzer contains a user-friendly interface that is flexibly designed to accommodate multiple endpoints depending upon the specific clinical condition being considered. The interface is LCD, 16x2, with a white backlight, variable delay auto-off time-out. Two status LED indicators are visible through front panel mounted lenses. Further, the reader contains three DPDT push-button switches (Left, Center, Right), power on button(s) for battery mode operation, switch usage switch, audible alerts, strip detection, and test completion signals.

Further, the RedoxSYS analyzer enables data transfer, has USB serial communication, and is configured for data download to a connected PC.

The RedoxSYS analyzer’s power management consists of an external 5VDC power jack with input capacitance and filtering, a boost converter supplied by external 5VDC power or internal Li-Ion battery, and provides main 5VDC digital board supply. The reader functions with or without the battery connected. The battery lasts in excess of 24 hours with continuous operation to enable prolonged use outside of a laboratory setting.

The ORP sensor strips, via standard biological specimen collection techniques, receive 20-40 microliters of a specimen from which the ORP clinical analysis is performed. The ORP sensor strips are small, disposable, and biocompatible and consist of a ceramic substrate and a five-lead configuration. Significant intellectual property surrounds the design, construct, and electrochemical algorithms associated with the sensors.

We have begun clinical studies in male infertility with a prominent, U.S.-based university medical center utilizing the newly developed MiOXSYS System. If successful, we anticipate we will demonstrate the MiOXSYS System’s ability to measure oxidative stress in semen samples as an adjunctive measure of infertility. These studies are summarized below:

Results from these clinical studies could validate that the MiOXSYS System can be used for detection of ORP in human ejaculates and seminal plasma without requiring large sample volumes. Furthermore, it can show that the results obtained are comparable to the current parameters measured. This could validate the use of the MiOXSYS System in the clinical andrology setting as a tool to provide real time information on oxidative status. If successful, these studies will provide substantial clinical validation for use of the MiOXSYS System in male infertility and enable a specific clinical application in the field of andrology and male infertility.

Beyond male infertility, we have generated robust clinical data with ORP. As much of our initial research efforts focused on trauma, research beginning in 2014 has expanded into research and clinical applications in the areas of:

Additionally, we have conducted numerous pre-clinical studies looking at various neurodegenerative conditions including Parkinson’s disease and multiple sclerosis. We have active research in place with over 20 key opinion leaders around the world with over 80 studies in various stages or planning or execution.

In 2013 and 2014, we deployed the RedoxSYS System around the world in the development of numerous future clinical applications. While many areas of study have been undertaken, we have focused research resources on high-value areas where significant medical needs remain unmet. Given our initial orientation around trauma, the studies completed thus far have focused on large conditions related to critical care. These initial studies demonstrated the initial clinical validation for the RedoxSYS and MiOXSYS systems and represent substantial opportunities as growth applications and markets following initial entry into the research and infertility markets.

We have initiated over 80 studies across a range of study types, ranging from studies in trauma, liver disease, diabetes, cardiac conditions, wellness/exercise, and fertility. From this research has presented unique opportunities to deploy the RedoxSYS System to users in multiple markets around the world in various conditions. With a CE marking now in place and research instruments now manufactured and ready for use, we are positioned to begin commercializing the RedoxSYS System.

Significant research has been performed on the ORP diagnostic platform, and numerous peer-reviewed publications demonstrate the various considerations made in the development of this application in a clinical setting. Further, the research conducted to date demonstrates the clinical relevance of ORP as a diagnostic marker in trauma, the development of transfusion-related acute lung injury, or TRALI, via blood transfusions, and other conditions. Over the past 20 years, Ampio/DMI Bioscience employees, Dr. Bar-Or, Raphael Bar-Or, Leonard Rael, and their colleagues, have employed the resources of two Level 1 trauma centers in the state of Colorado. Specific, select studies reporting on the clinical role of ORP as it relates to trauma, acute lung injury related to blood transfusions, and traumatic brain injury include:

We achieved ISO 13485: 2003 in early 2014 following the successful development of a compliant medical device quality system. Following the issuance of our ISO certification, we were awarded a CE marking for the RedoxSYS System, which has enabled initial market development in Europe and markets that accept a CE marking. We also received Health Canada clearance, and we are now working with multiple centers in Canada in research projects. In the United States, we intend to pursue 510k de novo clearance with the FDA for the MiOXSYS System.

If the clinical studies to measure oxidative stress in male infertility are successful, we expect to pursue that intended use for the MiOXSYS System via the FDA 510k de novo pathway. If cleared for the intended use, we intend to seek to commercialize MiOXSYS System as a new tool for the assessment of oxidative stress in infertility in men. We envision pursuing a direct sales effort to high priority urology/andrology laboratories, infertility clinics and reference centers across the United States. We have identified the primary, influential centers in the United States and believe our commercial deployment will be efficient through a focused sales and marketing effort. We intend to seek to sell

the MiOXSYS System into individual centers and laboratories but will focus our revenue model on the repeat ordering of the disposable, single use MiOXSYS sensor strips. We expect to realize a substantial gross margin and profit margin on the basis of low cost of goods sold on both components of the system. We envision an average selling price for the disposable sensors of approximately $25-$40. We envision selling the MiOXSYS analyzers for $5,500 but will also pursue an instrument rental agreement model with minimum disposable sensor purchase requirements.

We also intend to leverage our urology commercialization efforts with other products with a focus on urology centers, infertility clinics, and reproductive health laboratories around the United States.

We believe a focused sales force at the onset of commercialization will enable effective representation of our products and penetration of the reproductive health market. Our sales efforts into the research markets will be enabled initially through a full-time business development professional who will focus on collaborative research and research sales to major oxidative stress centers in the United States. We expect identical pricing in the research market as we intend to pursue in the clinical diagnostics markets.

We intend to undertake a similar strategy outside the United States for the RedoxSYS and MiOXSYS systems while complementing our efforts in infertility and research with adjunct applications in critical care conditions. To efficiently execute across our strategy, we intend to utilize a network of established distributors in the target markets in Europe and Asia. We have already engaged with distributors in three European countries and one Asian country, while many other potential distributors are in advanced stages of discussions with us. We anticipate slightly reduced pricing outside the United States for the disposable sensors given the anticipated lower pricing observed ex-U.S. for diagnostic and research products.

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act, or the FDC Act, and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, and criminal prosecution.

Pharmaceutical product development in the United States typically involves the performance of satisfactory nonclinical, also referred to as pre-clinical, laboratory and animal studies under the FDA’s Good Laboratory Practice, or GLP, regulation, the development and demonstration of manufacturing processes, which conform to FDA mandated current good manufacturing requirements, or cGMP, including a quality system regulating manufacturing, the submission and acceptance of an IND application, which must become effective before human clinical trials may begin in the United States, obtaining the approval of Institutional Review Boards, or IRBs, at each site where we plan to conduct a clinical trial to protect the welfare and rights of human subjects in clinical trials, adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought, and the submission to the FDA for review and approval of an NDA. Satisfaction of FDA requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity, and novelty of the product or disease.

Pre-clinical tests generally include laboratory evaluation of a product candidate, its chemistry, formulation, stability and toxicity, as well as certain animal studies to assess its potential safety and efficacy. Results of these pre-clinical tests, together with chemistry, manufacturing controls and analytical data and the clinical trial protocol, which details the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated, along with other requirements must be submitted to the FDA as part of an IND, which must become effective before human clinical trials can begin. The entire clinical trial and its protocol must be in compliance with what are referred to as good clinical practice, or GCP, requirements. The term, GCP, is used to refer to various FDA laws and regulations, as well as international scientific standards intended to protect the rights, health and safety of patients, define the roles of clinical trial sponsors and assure the integrity of clinical trial data.

An IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the intended conduct of the trials and imposes what is referred to as a clinical hold. Pre-clinical studies generally take several years to complete, and there is no guarantee that an IND based on those studies will become effective, allowing clinical testing to begin. In addition to FDA review of an IND, each medical site that desires to participate in a proposed clinical trial must have the protocol reviewed and approved by an independent IRB or Ethics Committee, or EC. The IRB considers, among other things, ethical factors, and the selection and safety of human subjects. Clinical trials must be conducted in accordance with the FDA’s GCP requirements. The FDA and/or IRB may order the temporary, or permanent, discontinuation of a clinical trial or that a specific clinical trial site be halted at any time, or impose other sanctions for failure to comply with requirements under the appropriate entity jurisdiction.

Clinical trials to support NDAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1 clinical trials, a product candidate is typically introduced either into healthy human subjects or patients with the medical condition for which the new drug is intended to be used. The main purpose of the trial is to assess a product candidate’s safety and the ability of the human body to tolerate the product candidate. Phase 1 clinical trials generally include less than 50 subjects or patients. During Phase 2 trials, a product candidate is studied in an exploratory trial or trials in a limited number of patients with the disease or medical condition for which it is intended to be used in order to: (i) further identify any possible adverse side effects and safety risks, (ii) assess the preliminary or potential efficacy of the product candidate for specific target diseases or medical conditions, and (iii) assess dosage tolerance and determine the optimal dose for Phase 3 trials. Phase 3 trials are generally undertaken to demonstrate clinical efficacy and to further test for safety in an expanded patient population with the goal of evaluating the overall risk-benefit relationship of the product candidate. Phase 3 trials are generally designed to reach a specific goal or endpoint, the achievement of which is intended to demonstrate the candidate product’s clinical efficacy and adequate information for labeling of the approved drug.

There are three main types of NDAs, which are covered by Section 505 of the FDC Act: (1) an application that contains full reports of investigations of safety and efficacy (Section 505(b)(1)); (2) an application that contains full reports of investigations of safety and effectiveness but where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the application has not obtained a right of reference (Section 505(b)(2)); and (3) an application that contains information to show that the proposed product is identical in active ingredient, dosage form, strength, route of administration, labeling, quality, performance characteristics, and intended use, among other things, to a previously approved product (Section 505(j)). Section 505(b)(2) expressly permits the FDA to rely, for approval of an NDA, on data not developed by the applicant. In the pre-IND briefing meeting with Ampio and in June 2012, the FDA agreed that our NDA may be submitted under Section 505(b)(2). As such, we intend to rely on studies published in the scientific literature and reference FDA-approved NDAs for tramadol-containing products (NDAs 21-693, 20-281 and 21-692) to support the safety and efficacy demonstrated in our clinical program.

After completion of the required clinical testing, an NDA is prepared and submitted to the FDA. FDA approval of the NDA is required before marketing of the product may begin in the U.S. The NDA must include the results of all pre-clinical, clinical, and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture, and controls. The cost of preparing and submitting an NDA is substantial. Under federal law, the submission of most NDAs is additionally subject to a substantial application user fee, currently exceeding $2.3 million and the manufacturer and/or sponsor under an approved NDA are also subject to annual product and establishment user fees, currently approximately $0.1 million per product and $0.6 million per establishment. These fees are typically increased annually.

The FDA has 60 days from its receipt of an NDA to determine whether the application will be accepted for filing based on the FDA’s threshold determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of NDAs. Most such applications for standard review drug products are reviewed within ten months; most applications for priority review drugs are reviewed in six months. Priority review can be applied to drugs that the FDA determines offer major advances in treatment, or provide a treatment where no adequate therapy exists. The review process for both standard and priority review may be extended by the FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already

provided in the submission. The FDA may also refer applications for novel drug products, or drug products which present difficult questions of safety or efficacy, to an advisory committee—typically a panel that includes clinicians and other experts—for review, evaluation, and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. The FDA will not approve the product unless compliance with cGMP is satisfactory and the NDA contains data that provide substantial evidence that the drug is safe and effective in the indication studied.

After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications. As a condition of NDA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug outweigh the potential risks.

REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability of the drug. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the drug’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing.

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent whose claims cover the applicant’s product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential competitors in support of approval of an abbreviated new drug application, or ANDA. An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been shown through bioequivalence testing to be therapeutically equivalent to the listed drug. Other than the requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, pre-clinical or clinical tests to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the listed drug, and can often be substituted by pharmacists under prescriptions written for the original listed drug.

The ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book that: 1) the required patent information has not been filed; 2) the listed patent has expired; 3) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or 4) the listed patent is invalid or will not be infringed by the new product. A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are invalid, is called a Paragraph IV certification. If the applicant does not challenge the listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.

If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA applicant.

The ANDA application also will not be approved until any non-patent exclusivity listed in the Orange Book for the referenced product has expired. Federal law provides a period of five years following approval of a drug containing no previously approved active ingredients during which ANDAs for generic versions of those drugs cannot be submitted, unless the submission contains a Paragraph IV challenge to a listed patent—in which case the submission may be made four years following the original product approval. Federal law provides for a period of three years of exclusivity during which FDA cannot grant effective approval of an ANDA based on the approval of a listed drug that contains previously approved active ingredients but is approved in a new dosage form, route of administration or combination, or for a new use; the approval of which was required to be supported by new clinical trials conducted by, or for, the applicant.

Even if a product candidate receives regulatory approval, the approval is typically limited to specific clinical indications. Further, even after regulatory approval is obtained, subsequent discovery of previously unknown problems with a product may result in restrictions on its use or even complete withdrawal of the product from the market. Any FDA-approved products manufactured or distributed by us are subject to continuing regulation by the FDA, including record-keeping requirements and reporting of adverse events or experiences. Further, drug manufacturers and their subcontractors are required to register their establishments with the FDA and state agencies, and are subject to periodic inspections by the FDA and state agencies for compliance with cGMP, which impose rigorous procedural and documentation requirements upon us and our contract manufacturers. We cannot be certain that we or our present or future contract manufacturers or suppliers will be able to comply with cGMP regulations and other FDA regulatory requirements. Failure to comply with these requirements may result in, among other things, total or partial suspension of production activities, failure of the FDA to grant approval for marketing, and withdrawal, suspension, or revocation of marketing approvals.

If the FDA approves one or more of our product candidates, we and the contract manufacturers we use for manufacture of clinical supplies and commercial supplies must provide certain updated safety and efficacy information. Product changes, as well as certain changes in the manufacturing process or facilities where the manufacturing occurs or other post-approval changes may necessitate additional FDA review and approval. The labeling, advertising, promotion, marketing and distribution of a drug or biologic product or medical devices, also must be in compliance with FDA and Federal Trade Commission, or FTC, requirements which include, among others, standards and regulations for direct-to-consumer advertising, off-label promotion, industry sponsored scientific and educational activities, and promotional activities involving the Internet. The FDA and FTC have very broad enforcement authority, and failure to abide by these regulations can result in penalties, including the issuance of a warning letter directing us to correct deviations from regulatory standards and enforcement actions that can include seizures, fines, injunctions and criminal prosecution.

In the United States, the FDCA, FDA regulations and other federal and state statutes and regulations govern, among other things, medical device design and development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, sales and distribution, export and import, and post-market surveillance. The FDA regulates the design, manufacturing, servicing, sale and distribution of medical devices, including molecular diagnostic test kits and instrumentation systems. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending applications, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties and criminal prosecution.

Unless an exemption applies, each medical device we wish to distribute commercially in the United States will require marketing authorization from the FDA prior to distribution. The two primary types of FDA marketing authorization applicable to a device are premarket notification, also called 510(k) clearance, and premarket approval, also called PMA approval. The type of marketing authorization is generally linked to the classification of the device. The FDA classifies medical devices into one of three classes (Class I, II or III) based on the degree of risk the FDA determines to be associated with a device and the level of regulatory control deemed necessary to ensure the device’s safety and effectiveness. Devices requiring fewer controls because they are deemed to pose lower risk are placed in Class I or II. Class I devices are deemed to pose the least risk and are subject only to general controls applicable to all devices, such as requirements for device labeling, premarket notification and adherence to the FDA’s current Good Manufacturing Practices, or cGMP, known as the Quality System Regulations, or QSR. Class II devices are intermediate risk devices that are subject to general controls and may also be subject to special

controls such as performance standards, product-specific guidance documents, special labeling requirements, patient registries or post-market surveillance. Class III devices are those for which insufficient information exists to assure safety and effectiveness solely through general or special controls and include life sustaining, life-supporting or implantable devices, devices of substantial importance in preventing impairment of human health, or which present a potential, unreasonable risk of illness or injury.

Most Class I devices and some Class II devices are exempted by regulation from the 510(k) clearance requirement and can be marketed without prior authorization from the FDA. Some Class I devices that have not been so exempted and Class II devices are eligible for marketing through the 510(k) clearance pathway. By contrast, devices placed in Class III generally require PMA approval or 510(k) de novo clearance prior to commercial marketing. The PMA approval process is more stringent, time-consuming and expensive than the 510(k) clearance process, however, the 510(k) clearance process has also become increasingly stringent and expensive. The FDA has provided initial guidance to us that the RedoxSYS System is appropriate for the 510(k) clearance process, likely through the de novo pathway.

510(k) Clearance. To obtain 510(k) clearance for a medical device, an applicant must submit a premarket notification to the FDA demonstrating that the device is “substantially equivalent” to a device legally marketed in the United States that is not subject to PMA approval, commonly known as the “predicate device.” A device is substantially equivalent if, with respect to the predicate device, it has the same intended use and has either (i) the same technological characteristics or (ii) different technological characteristics and the information submitted demonstrates that the device is as safe and effective as a legally marketed device and does not raise different questions of safety or effectiveness. A showing of substantial equivalence sometimes, but not always, requires clinical data. Generally, the 510(k) clearance process can exceed 90 days and may extend to a year or more.

Application fees must accompany medical device submissions. Such fees under the Medical Device User Fees Act, or MDUFA, for 2015 are approximately $258,000 for a full fee application and approximately $5,000 for a 510(k). Fees are adjusted annually.

There are also establishment registration and reporting fees of approximately $4,000 and $9,000, respectively.

After a device has received 510(k) clearance for a specific intended use, any change or modification that significantly affects its safety or effectiveness, such as a significant change in the design, materials, method of manufacture or intended use, may require a new 510(k) clearance or PMA approval and payment of an FDA user fee. The determination as to whether or not a modification could significantly affect the device’s safety or effectiveness is initially left to the manufacturer using available FDA guidance; however, the FDA may review this determination to evaluate the regulatory status of the modified product at any time and may require the manufacturer to cease marketing and recall the modified device until 510(k) clearance or PMA approval is obtained. The manufacturer may also be subject to significant regulatory fines or penalties.

Before we can submit a medical device for 510(k) clearance, we may have to perform a series of generally short studies over a period of months, including method comparison, reproducibility, interference and stability studies to ensure that users can perform the test successfully. Some of these studies may take place in clinical environments, but are not usually considered clinical trials. For PMA submissions, we would generally be required to conduct a longer clinical trial over a period of years that supports the clinical utility of the device and how the device will be used.

Although clinical investigations of most devices are subject to the investigational device exemption, or IDE, requirements, clinical investigations of diagnostic tests, including our products and products under development, are generally exempt from the IDE requirements. Thus, clinical investigations by intended users for intended uses of our products generally do not require the FDA’s prior approval but may require approval of an Institutional Review Board, or IRB, and written informed consent by the patient, provided the clinical evaluation testing is non-invasive, does not require an invasive sampling procedure that presents a significant risk, does not intentionally introduce energy into the subject and is not used as a diagnostic procedure without confirmation by another medically established test or procedure. In addition, our products must be labeled per FDA regulations “for research use only-RUO” or “for investigational use only-IUO,” and distribution controls must be established to assure that our products distributed for research, method comparisons or clinical evaluation studies are used only for those purposes.

Any devices we manufacture or distribute pursuant to clearance or approval by the FDA are subject to pervasive and continuing regulation by the FDA and certain state agencies. We are required to adhere to applicable regulations setting forth detailed cGMP requirements, as set forth in the QSR, which include, among other things, testing, control and documentation requirements. Noncompliance with these standards can result in, among other things, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension of production, refusal of the government to grant 510(k) clearance or PMA approval of devices, withdrawal of marketing approvals and criminal prosecutions, fines and imprisonment. Our contract manufacturers’ facilities operate under the FDA’s cGMP requirements.

Outside of the United States, our ability to market our product candidates will be contingent also upon our receiving marketing authorizations from the appropriate foreign regulatory authorities, whether or not FDA approval has been obtained. The foreign regulatory approval process in most industrialized countries generally encompasses risks similar to those we will encounter in the FDA approval process. The requirements governing conduct of clinical trials and marketing authorizations, and the time required to obtain requisite approvals, may vary widely from country to country and differ from those required for FDA approval.

In the European Union, we are required under the European Medical Device Directive (Council Directive 93/42/EEC) to affix the CE mark to certain of our products in order to sell the products in member countries of the European Union. The CE mark is an international symbol that represents adherence to certain essential principles of safety and effectiveness mandated in the European Medical Device Directive, which are referred to as the “essential requirements”. Once affixed, the CE mark enables a product to be sold within the European Economic Area, or EEA, which is composed of the 28 member states of the EU plus Norway, Iceland and Liechtenstein as well as other countries that accept the CE mark.

To demonstrate compliance with the essential requirements, we must undergo a conformity assessment procedure which varies according to the type of medical device and its classification. Except for low risk medical devices (Class I with no measuring function and which are not sterile) where the manufacturer can issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the Medical Devices Directive, a conformity assessment procedure requires the intervention of an organization accredited by a member state of the EEA to conduct conformity assessments, or a notified body. Depending on the relevant conformity assessment procedure, the notified body would typically audit and examine the technical file and the quality system for the manufacture, design and final inspection of our devices. The notified body issues a CE certificate of Conformity following successful completion of a conformity assessment procedure conducted in relation to the medical device and its manufacturer and their conformity with the essential requirements. This certificate entitles the manufacturer to affix the CE mark to its medical devices after having prepared and signed a related EC Declaration of Conformity.

If we modify our devices we may need to apply for permission to affix the CE mark to the modified product. Additionally, we may need to apply for a CE mark for any new products that we may develop in the future. Certain products regulated as medical devices according to EC-Directives are subject to vigilance requirements for reporting of adverse events.

We will be subject to additional regulations in other countries in which we market, sell and import our products, including Canada. We or our distributors must receive all necessary approvals or clearance prior to marketing and/or importing our products in those markets.

The International Standards Organization, or ISO, promulgates internationally recognized standards, including those for the requirements of quality systems. To support ISO certifications, surveillance audits are conducted by a notified body yearly and recertification audits every three years that assess continued compliance with the relevant ISO standards.

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the United States, the Centers for Medicare & Medicaid Services, other divisions of the Department of Health and Human Services, the Drug Enforcement

Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency and state and local governments. In the United States, sales, marketing and scientific/educational programs must also comply with state and federal fraud and abuse laws. Pricing and rebate programs must comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Health Care Reform Law, as amended by the Health Care and Education Affordability Reconciliation Act, or ACA. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion and other activities are also potentially subject to federal and state consumer protection and unfair competition laws.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive recordkeeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines, imprisonment or other penalties, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, including government contracts. In addition, even if a firm complies with FDA and other requirements, new information regarding the safety or effectiveness of a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of future products marketed by us could materially affect our business in an adverse way.

Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

Depending upon the timing, duration and other specific aspects of the FDA approval of our drug candidates, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, if any of our NDA’s are approved, we intend to apply for restoration of patent term for one of our currently owned or licensed patents to add patent life beyond the current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant NDA.

Market exclusivity provisions under the FDCA can also delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity, or NCE. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. Recently, the FDA stated that it may change its interpretation of 5-year NCE exclusivity determinations to apply to each drug substance in a fixed-combination drug product, not for the drug product as a whole. If this change is implemented, for example, a fixed-combination drug product that contains a drug substance with a single, new active moiety would be eligible for 5 year NCE exclusivity, even if the fixed-combination also contains a drug substance with a previously approved active moiety. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application, or ANDA, or a Section 505(b)(2) NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the same indication as the original innovator drug or for another

indication, where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. The FDCA also provides three years of marketing exclusivity for an NDA, or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the pre-clinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. Orphan drug exclusivity, as described above, may offer a seven-year period of marketing exclusivity, except in certain circumstances. Pediatric exclusivity is another type of regulatory market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric trial in accordance with an FDA-issued “Written Request” for such a trial.

We do not anticipate that the sales of two of our product candidates (Zertane and the RedoxSYS System), once approved for sale, will be heavily dependent upon reimbursement by third-party payors. Traditionally, sales of pharmaceutical products that are not “life style” indications depend, in part, on the extent to which products will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. These third-party payors are increasingly reducing reimbursements for medical products and services. ProstaScint is dependent upon reimbursement for continued use in the U.S. market, and ProstaScint does have a reimbursement code as assigned by the American Medical Association. ProstaScint is currently reimbursed by Medicare, Medicaid, and various private health plans. However, reimbursement is not universally available throughout the United States for ProstaScint.

Lack of third-party reimbursement for our product candidate or a decision by a third-party payor to not cover our product candidates could reduce physician usage of the product candidate and have a material adverse effect on our sales, results of operations and financial condition.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products. Historically, products launched in the European Union do not follow price structures of the United States and generally tend to be significantly lower.

Zertane, because it contains tramadol, will be regulated as a “controlled substance” as defined in the Controlled Substances Act of 1970, or CSA, and the U.S. Drug Enforcement Agency’s, or DEA, implementing regulations, which establish registration, security, recordkeeping, reporting, storage, distribution, importation, exportation, inventory, quota and other requirements administered by the DEA. These requirements are directly applicable to us and also applicable to our manufacturers and to distributors, prescribers and dispensers of Zertane. The DEA regulates the handling of controlled substances through a closed chain of distribution. This control extends to the equipment and raw materials used in their manufacture and packaging in order to prevent loss and diversion into illicit channels of commerce.

We expect that Zertane will be listed by the DEA as Schedule IV controlled substances under the CSA. Consequently, any importation of API for Zertane, as well as the manufacture, shipping, storage, sales and use of Zertane, will be subject to a high degree of regulation. Also, distribution and dispensing of these drugs are highly regulated.

Annual registration is required for any facility that manufactures, distributes, dispenses, imports or exports any controlled substance. The registration is specific to the particular location, activity and controlled substance schedule. For example, separate registrations are needed for import and manufacturing, and each registration will specify which schedules of controlled substances are authorized. Similarly, separate registrations are also required for separate facilities.

The DEA typically inspects a facility to review its security measures prior to issuing a registration and on a periodic basis. Reports must also be made for thefts or losses of any controlled substance, and to obtain authorization to destroy any controlled substance. In addition, special permits and notification requirements apply to imports and exports of narcotic drugs.

The DEA establishes annually an aggregate quota for how much of a controlled substance may be produced in total in the United States based on the DEA’s estimate of the quantity needed to meet legitimate scientific and medicinal needs. The DEA may adjust aggregate production quotas and individual production and procurement quotas from time to time during the year, although the DEA has substantial discretion in whether or not to make such adjustments. Our or our manufacturers’ quotas of an active ingredient may not be sufficient to meet commercial demand or complete clinical trials. Any delay, limitation or refusal by the DEA in establishing our or our manufacturers’ quota for controlled substances could delay or stop our clinical trials or product launches, which could have a material adverse effect on our business, financial position and results of operations.

To enforce these requirements, the DEA conducts periodic inspections of registered establishments that handle controlled substances. Failure to maintain compliance with applicable requirements, particularly as manifested in loss or diversion, can result in administrative, civil or criminal enforcement action that could have a material adverse effect on our business, results of operations and financial condition. The DEA may seek civil penalties, refuse to renew necessary registrations, or initiate administrative proceedings to revoke those registrations. In some circumstances, violations could result in criminal proceedings.

Individual states also independently regulate controlled substances. We and our manufacturers will be subject to state regulation on distribution of these products, including, for example, state requirements for licensures or registration.

The current Vyrix patent portfolio consists of 79 issued patents and nine pending applications worldwide. The portfolio primarily consists of three families filed in the United States and throughout the world. The first family includes 30 issued patents for the use of tramadol to treat premature ejaculation. The standard 20-year expiration for patents in this family is in 2022. The other two families are for the use of a combination of tramadol and a phosphodiesterase inhibitor to treat comorbid premature ejaculation and erectile dysfunction and to treat sexual dysfunction side effects associated with administration of tramadol. These two families include issued patents in Europe, Australia, Canada, China, Mexico, New Zealand, Japan, the Philippines and South Africa and pending applications in the United States, Brazil, China, India, Japan, Korea, and the Philippines. The standard 20-year expiration for patents in these families is in 2028.

The current RedoxSYS/MiOXSYS patent portfolio consists of 14 issued patents and 56 pending applications worldwide. The portfolio primarily consists of four families filed in the United States and throughout the world. The first family includes four issued patents and five pending applications with claims directed to the measurement of the ORP of a patient sample to evaluate various conditions. The standard 20-year expiration for patents in this family is in 2028. The second family includes two pending United States applications, and nine pending applications worldwide with claims directed to the measurement of the ORP capacity of a patient sample to evaluate various conditions. The standard 20-year expiration for patents in this family is in 2033. The third family includes eight issued patents and 18 pending applications with claims directed to devices and methods for the measurement of ORP and ORP capacity. The standard 20-year expiration for patents in this family is in 2032. The fourth family includes one pending United States application and 16 pending applications worldwide with claims directed to multiple layer gel test strip measurement devices and methods of making for use in measuring ORP and ORP capacity. The standard 20-year expiration for patents in this family is in 2033.

ProstaScint is protected by significant trade secrets, manufacturing know how related to the production of the product’s base monoclonal antibody, and a highly protected proprietary cell line.

We also maintain trade secrets and proprietary know-how that we seek to protect through confidentiality and nondisclosure agreements. These agreements may not provide meaningful protection or adequate remedies in the event of unauthorized use or disclosure of confidential and proprietary information. If we do not adequately protect our trade secrets and proprietary know-how, our competitive position and business prospects could be materially harmed.

We expect to seek United States and foreign patent protection for drug and diagnostic products we discover, as well as therapeutic and diagnostic products and processes. We expect also to seek patent protection or rely upon trade secret rights to protect certain other technologies which may be used to discover and characterize drugs and diagnostic products and processes, and which may be used to develop novel therapeutic and diagnostic products and processes.

The patent positions of companies such as ours involve complex legal and factual questions and, therefore, their enforceability cannot be predicted with any certainty. Our issued and licensed patents, and those that may be issued to us in the future, may be challenged, invalidated or circumvented, and the rights granted under the patents or licenses may not provide us with meaningful protection or competitive advantages. Our competitors may independently develop similar technologies or duplicate any technology developed by us, which could offset any advantages we might otherwise realize from our intellectual property. Furthermore, even if our product candidates receive regulatory approval, the time required for development, testing, and regulatory review could mean that protection afforded us by our patents may only remain in effect for a short period after commercialization. The expiration of patents or license rights we hold could adversely affect our ability to successfully commercialize our pharmaceutical drugs or diagnostics, thus harming our operating results and financial position.

We will be able to protect our proprietary intellectual property rights from unauthorized use by third parties primarily to the extent that such rights are covered by valid and enforceable patents or are effectively maintained as trade secrets. If we must litigate to protect our intellectual property from infringement, we may incur substantial costs and our officers may be forced to devote significant time to litigation-related matters. The laws of certain foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States.

Our pending patent applications, or those we may file or license from third parties in the future, may not result in patents being issued. Until a patent is issued, the claims covered by an application for patent may be narrowed or removed entirely, thus depriving us of adequate protection. As a result, we may face unanticipated competition, or conclude that without patent rights the risk of bringing product candidates to market exceeds the returns we are likely to obtain. We are generally aware of the scientific research being conducted in the areas in which we focus our research and development efforts, but patent applications filed by others are maintained in secrecy for at least 18 months and, in some cases in the United States, until the patent is issued. The publication of discoveries in scientific literature often occurs substantially later than the date on which the underlying discoveries were made. As a result, it is possible that patent applications for products similar to our drug or diagnostic products and product candidates may have already been filed by others without our knowledge.

The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights, and it is possible that our development of products and product candidates could be challenged by other pharmaceutical or biotechnology companies. If we become involved in litigation concerning the enforceability, scope and validity of the proprietary rights of others, we may incur significant litigation or licensing expenses, be prevented from further developing or commercializing a product or product candidate, be required to seek licenses that may not be available from third parties on commercially acceptable terms, if at all, or subject us to compensatory or punitive damage awards. Any of these consequences could materially harm our business.

The healthcare industry is highly competitive and subject to significant and rapid technological change as researchers learn more about diseases and develop new technologies and treatments. Significant competitive factors in our industry include product efficacy and safety; quality and breadth of an organization’s technology; skill of an

organization’s employees and its ability to recruit and retain key employees; timing and scope of regulatory approvals; government reimbursement rates for, and the average selling price of, products; the availability of raw materials and qualified manufacturing capacity; manufacturing costs; intellectual property and patent rights and their protection; and sales and marketing capabilities.

We cannot assure you that any of our products that we successfully develop will be clinically superior or scientifically preferable to products developed or introduced by our competitors.

PE has traditionally been treated by behavioral or psychosexual therapy, antidepressant drugs, such as SSRIs, or topical desensitizing agents, all of which have significant drawbacks. Behavioral and psychosexual therapy as a treatment for PE requires an understanding partner and can be frustrating, embarrassing, time consuming and expensive, among other things. Antidepressant drugs are sometimes prescribed “off-label” and have numerous shortcomings, including side effects such as nausea, headaches, drop of libido, and ED, need for chronic dosing, ramp up periods, variable responses and unwanted drug-drug interactions. Topical agents, including lidocaine-based products affect spontaneity, can numb a partner and be messy.

Dapoxetine (brand name Priligy, owned by Furiex Pharmaceuticals, Inc, which is owned by Actavis plc, is currently the only approved oral prescription drug to treat PE, with approval in several European countries. Priligy is not approved in the United States. In addition, we are aware of a topical product in late-stage development for PE by Plethora Solutions referred to as PSD502 and studies of Botox for the treatment of PE are being conducted in the United States. These products – if approved in the United States – would represent competition and alternative choices for physicians and potential patients.

In addition, generic tramadol hydrochloride is available in the United States and abroad for treatment of pain. Although the generic drug is not available in the same dosage as Zertane for treatment of PE, it is possible that physicians could prescribe the generic version of the drug “off label” for the treatment of PE instead of Zertane, if Zertane is approved for commercialization. Patients could use generic tramadol hydrochloride dosages that are either higher or lower than what will be approved for Zertane or they could attempt to split dosages to arrive at the dosages approved for Zertane. While any such “off label” use of generic tramadol hydrochloride for treatment of PE may constitute infringement of the Vyrix patent portfolio, liability in that circumstance would be at the level of the physician or the patient making enforcement difficult or impractical.

Currently, there are several FDA approved imaging techniques for cancer in general, however there is only one specifically targeting prostate cancer - ProstaScint. The other imaging methods are F18-fluorodeoxyglucose (F18-FDG), C11-Acetate, and C11-Choline. The primary advantage of these methods is that they all use PET imaging, a technique with better resolution than SPECT. The use of PET is also a disadvantage, however, since it uses radiolabels with short half-lives necessitating the need for a local or on-site cyclotron to generate the labels. The half-life of fluorine-18 (F18) and of carbon-11 (C11) are approximately 110 and 20 minutes, respectively. The radiolabel used by ProstaScint is Indium-11, with a half-life of about 2-3 days. This longer time period allows the radiolabel to be made remotely and shipped to the imaging facility; however it does use SPECT as the imaging modality.

As indicated, ProstaScint is the only radio-imaging marker that is specific for prostate cancer. ProstaScint is based on radiolabeling the antibody against prostate specific membrane antigen, or PSMA, a protein express by prostate cells. This specificity for prostate cells is what allows ProstaScint to detect the metastases of prostate cancer regardless of location. The mechanism of labeling for F18-FDG, C11-Acetate, and C11-Choline is the intracellular accumulation of these markers in cancer cells, due to the fact that cancer cells typically have a higher cellular metabolism than non-cancerous cells. Thus, these markers can accumulate in any type of cancer cell with a high metabolism, unfortunately prostate cancer cells tend to have a lower cellular metabolism resulting in higher false positives attributed to hyperplasia and prostatitis.

In a meta-analysis of 21 studies evaluating accuracy, sensitivity, specificity, positive/negative predictive values, ProstaScint using combined SPECT/CT imaging was comparable to PET/CT imaging based on F18-FDG and C11-Choline.

There are other oxidative stress diagnostic tests available throughout the world, although none are approved in the United States for clinical use. Diagnostic systems that are marketed for clinical use outside the United States include the FRAS 4 system (H&D srl), FREE Carpe Diem (Diacron International), and the FORM and FORMPlus systems

(Callegari srl). These systems are used in both research and clinical settings but do not generate significant sales in the clinical setting. If approved in the United States for clinical use, these systems could present competition to the RedoxSYS System.

Our competitors may also succeed in obtaining FDA or other regulatory approvals for their product candidates more rapidly than we are able to do, which could place us at a significant competitive disadvantage or deny us marketing exclusivity rights. Market acceptance of our product candidates will depend on a number of factors, including: (i) potential advantages over existing or alternative therapies or tests, (ii) the actual or perceived safety of similar classes of products, (iii) the effectiveness of sales, marketing, and distribution capabilities, and (iv) the scope of any approval provided by the FDA or foreign regulatory authorities.

Although we believe our product candidates possess attractive attributes, we cannot assure you that our product candidates will achieve regulatory or market acceptance, or that we will be able to compete effectively in the pharmaceutical drug markets. If our product candidates fail to gain regulatory approvals and acceptance in their intended markets, we may not generate meaningful revenues or achieve profitability.

Our strategy is to minimize fixed overhead by outsourcing much of our research and development activities. We believe we will benefit from Ampio’s research and development experience as well as regulatory expertise. Additionally, we intend to utilize consultants with domain experience for research, development and regulatory guidance.

We have consulting agreements in place with two such companies who are actively participating with us on the impending clinical trials for Zertane. When we focus on Zertane-ED in the future, as planned, we intend to collaborate on pre-clinical studies and clinical trials with our partner in Korea, Daewoong Pharmaceuticals Co.

Our RedoxSYS System has been developed in conjunction with numerous medical device and diagnostic development consultants. Further, we have relationships with regulatory consultants who are actively assisting in the development of our regulatory strategy with the FDA. To complement our internal clinical research efforts with the RedoxSYS System, we have engaged with numerous universities around the world to identify and develop research and clinical applications for the RedoxSYS System. Through these engagements we have access to data and analyses that enable us to develop new uses for the RedoxSYS and MiOXSYS systems. Additionally, we have formal research agreements in place with two prominent U.S.-based universities and one prominent European university for which we are paying a research fee.

Our business strategy is to use cGMP compliant contract manufacturers for the manufacture of clinical supplies as well as for commercial supplies if required by our commercialization plans, and to transfer manufacturing responsibility to our collaboration partners when possible.

We are party to a 10-year supply agreement with an established manufacturer of tramadol hydrochloride for Zertane. Importantly, product supply has been produced for our planned clinical trials for Zertane.

We have acquired a two-year supply of ProstaScint through our asset purchase agreement with Jazz Pharmaceuticals. Further, we intend to intend to transfer the manufacturing of ProstaScint to a new contract manufacturer, and have initiated discussions with the contract manufacturer and expect to sign an agreement whereby we will transfer the production to a similar facility operated by the new contract manufacturer. Accordingly, we also expect to put a supply agreement in place for an extended duration.

We have completed the technical development of the RedoxSYS System by engaging contract development and manufacturing companies in the United States. We secured supply and quality agreements with manufacturers for both the RedoxSYS and MiOXSYS instruments as well as the RedoxSYS and MiOXSYS sensor strips. Both manufacturers hold long-standing ISO 13485:2003 certifications and are established medical device manufacturers. Both manufacturers have high volume manufacturing capacity such that production volumes can be easily scaled. Both manufacturers have been audited by our quality engineers and are fully compliant.

As of September 30, 2015, we had 12 full-time employees and utilized the services of a number of consultants on a temporary basis. Overall, we have not experienced any work stoppage and do not anticipate any work stoppage in the foreseeable future. None of our employees is subject to a collective bargaining agreement. Management believes that relations with our employees are good.

Pursuant to our services agreements with Ampio, we use a portion of Ampio’s office space as our office space, which is located in Englewood, Colorado. We have also opened a 1,333 square foot office in Raleigh, North Carolina for which the lease runs until July 31, 2018. Ampio’s lease expires in 2024, and our cost for the office space is included in our quarterly payment under the services agreements. We expect to establish a new office in the Englewood, Colorado area in the near future. We believe our current office space is sufficient to meet our current needs.

On August 19, 2015, Aytu entered into a 37 month non-cancellable operating lease for new office space effective September 1, 2015. The new lease has initial base rent of $8,500 per month beginning in October 2015, with the total base rent over the term of the lease of approximately $318,000 which includes rent abatements. We recognize rental expense of the facility on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent.

We are currently not party to any material legal or administrative proceedings and are not aware of any material pending or threatened legal or administrative proceedings in which we will become involved.

The following table sets forth the names and ages of all of our directors and executive officers as of June 30, 2015.

Jarrett T. Disbrow, our Chief Operating Officer, is the brother of Joshua R. Disbrow, our Chief Executive Officer. There are no other family relationships among or between any of our current or former executive officers and directors.

In accordance with Item 402 of Regulation S-K promulgated by the SEC, we are required to disclose certain information regarding the makeup of and compensation for our company’s directors, former directors and named executive officers, in certain cases for each of the last three completed fiscal years. On April 16, 2015, we acquired Luoxis and Vyrix in the Merger. Because our sole director was a director on the boards of directors of Luoxis and Vyrix, and our named executive officers were, prior to the April 16, 2015, employed by Luoxis and Vyrix, we are providing past compensation information concerning such director and executive officers with respect to Luoxis and Vyrix.

In establishing director compensation, our Board is guided by the following goals:

Jarrett T. Disbrow, who served as a member of Vyrix’s board of directors during 2014, did not receive any compensation, equity awards or non-equity awards for his service as a director, although Mr. Disbrow did receive

compensation in 2014 from and with respect to his employment with Vyrix. James B. Wiegand, who served as the sole director of Rosewind in 2014, did not receive any compensation, equity awards or non-equity awards for his service as a director. Mr. Wiegand was appointed President, Chief Executive Officer and Secretary and a director of Rosewind on August 9, 2002. He resigned from all of his positions with us on April 16, 2015.

We have not yet established a compensation package for our director, Michael Macaluso, our non-employee and sole director, and future non-employee directors other than reimbursement of expenses incurred in connection with their service as director.

The following table provides information regarding all compensation paid to non-employee directors of Vyrix and Luoxis during the fiscal year ended June 30, 2015.

From fiscal year 2012 to the completion of the Merger on April 16, 2015, no compensation was earned by or paid to James B. Wiegand, the former President, Chief Financial Officer and Secretary of Rosewind.

The following table sets forth all cash compensation earned, as well as certain other compensation paid or accrued for the years ended June 30, 2015 and 2014 to each of the following named executive officers.

Our executive officers are reimbursed by us for any out-of-pocket expenses incurred in connection with activities conducted on our behalf.

The following table sets forth certain information regarding grants of plan-based awards to the Named Executive Officers as of June 30, 2015:

We entered into an employment agreement with Joshua Disbrow in connection with his employment as our Chief Executive Officer. The agreement is for a term of 24 months beginning on April 16, 2015, subject to termination by us with or without Cause or as a result of officer’s disability, or by the officer with or without Good Reason (as discussed below). Mr. Disbrow is entitled to receive $250,000 in annual salary, plus a discretionary performance bonus with a target of 125% of his base salary and 600,000 stock options with 50% vesting upon grant and the remainder vesting on the following two anniversaries of the grant date. Mr. Disbrow is also eligible to participate in the benefit plans maintained by us from time to time, subject to the terms and conditions of such plans.

We entered into an employment agreement with Jarrett Disbrow, our Chief Operating Officer, in connection with his employment with us. The agreement is for a term of 24 months beginning on April 16, 2015, subject to termination by us with or without Cause or as a result of the officer’s disability, or by the officer with or without Good Reason (as discussed below). Mr. Disbrow is entitled to receive $250,000 in annual salary, plus a discretionary performance bonus with a target of 125% of his base salary and 600,000 stock options with 50% vesting upon grant and the remainder vesting on the following two anniversaries of the grant date. Mr. Disbrow is also eligible to participate in the benefit plans maintained by us from time to time, subject to the terms and conditions of such plans.

Pursuant to the employment agreements, in the event Mr. Joshua Disbrow’s or Mr. Jarrett Disbrow’s employment is terminated without Cause by us or either officer terminates his employment with Good Reason, we will be obligated to pay him any accrued compensation and a lump sum payment equal to two times his base salary in effect at the date of termination, as well as continued participation in the health and welfare plans for up to two years. All vested stock options shall remain exercisable from the date of termination until the expiration date of the applicable award. So long as a Change in Control is not in effect, then all options which are unvested at the date of termination Without Cause or for Good Reason shall be accelerated as of the date of termination such that the number of option shares equal to 1/24th the number of option shares multiplied by the number of full months of such officer’s employment shall be deemed vested and immediately exercisable by the officer. Any unvested options over and above the foregoing shall be cancelled and of no further force or effect, and shall not be exercisable by such officer.

The severance benefits described above are contingent on each officer executing a general release of claims.

Pursuant to the employment agreements, in the event of a Change in Control of us, all stock options, restricted stock and other stock-based grants granted or may be granted in the future by us to the officers will immediately vest and become exercisable.

Payments Provided Upon Termination for Cause or Without Good Reason, Death or Disability

Pursuant to the employment agreements, in the event we end the officer’s employment for Cause, if such officer resigns as an employee for reasons other than an event of Good Reason, such officer dies or disability occurs, then we shall pay to the officer the accrued compensation but shall have no obligation to pay the officer any amount, whether for salary, benefits, bonuses, or other compensation or expense reimbursements of any kind, accruing after the end of the employment, and such rights shall, except as otherwise required by law or pursuant to the applicable award agreement or plan, be forfeited immediately upon the end of the employment. For the sake of clarity, any stock options, restricted stock or other equity compensation shall, to the extent vested on the date of resignation without Good Reason, the date we end the employment for Cause, or the date of the officer’s death or disability, remain outstanding and exercisable to the extent provided in the applicable award agreement or plan, by the officer or his personal representative or executor.

We describe below all transactions and series of similar transactions, other than compensation arrangements, during the last three fiscal years, to which we were a party or will be a party, in which:

On April 16, 2015, pursuant to the Merger Agreement entered into among Rosewind, Luoxis, Vyrix and two subsidiaries of Rosewind created solely for the purposes of the Merger, and which did not survive the Merger, the Merger occurred in two stages.

In the first stage, each of Vyrix and Luoxis merged with one of Rosewind’s merger subsidiaries. Vyrix and Luoxis survived these mergers. The outstanding shares of stock of Vyrix and the outstanding shares of stock of Luoxis were converted into the right to receive shares of our common stock. The Vyrix stock and the Luoxis stock were each converted at an exchange factor. The exchange factor for each of them was determined upon the basis of a relative value opinion obtained by Ampio, the parent company of Vyrix and Luoxis. The outstanding shares of Rosewind’s merger subsidiary that merged with Vyrix were converted into shares of Vyrix as the surviving corporation. The outstanding shares of Rosewind’s merger subsidiary that merged with Luoxis were converted into shares of Luoxis as the surviving corporation. After completion of the first stage, Vyrix and Luoxis became subsidiaries of Rosewind.

In the second stage, which occurred on the same day as the first stage, each of Vyrix and Luoxis merged with Rosewind with Rosewind surviving. The first and second stage mergers are referred to collectively as the “Merger.”

As of August 31, 2014, Rosewind has a secured promissory note to the sole officer and director for $30,985 for working capital. The loan carries a 6% interest rate, matures on demand and is secured by the sailing vessel. Accrued interest payable on the loan totaled $17,607 as of August 31, 2014.

For the year ended August 31, 2014, the sole officer of Rosewind contributed services valued at $3,690. This amount has been booked to additional paid in capital.

On March 3, 2015, Rosewind accepted a cash investment from two irrevocable trusts for estate planning of which Joshua Disbrow and Jarrett Disbrow are beneficiaries. None of such persons have or share investment control over our shares held by such trusts. None of such persons, nor members of their respective immediate families, are trustees of such trusts. None of such persons have or share power to revoke such trusts. Accordingly, under Rule 16a-8(b) and related rules, none of such persons has beneficial ownership over our shares purchased and held by such trusts.

In November 2013, Vyrix entered into a loan agreement with Ampio. Pursuant to the loan agreement, Ampio agreed to lend Vyrix up to an aggregate amount of $3,000,000 through cash advances of up to $500,000 each. Unpaid principal amounts under the loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Vyrix may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Vyrix common stock at the fair market value per share of Vyrix common stock, as determined by the Ampio board of directors, as of such conversion date. On April 16, 2015, in connection with the closing of the Merger, Ampio released Vyrix from its then outstanding obligation of $4,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

In March 2014, Luoxis entered into a loan agreement with Ampio. Pursuant to the loan agreement, Ampio agreed to lend Luoxis $3,000,000. Unpaid principal amounts under the loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Luoxis may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Luoxis common stock at the fair market value per share of Luoxis common stock, as determined by the Ampio board of directors, as of such conversion date. On April 16, 2015, in connection with the closing of the Merger, Ampio released Luoxis from its then outstanding obligation of $8,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

On April 16, 2015, Ampio received 4,761,787 shares of common stock of Aytu for (i) issuance to Aytu of a promissory note from Ampio in the principal amount of $10,000,000, maturing on the first anniversary of the Merger, (ii) cancellation of indebtedness of Luoxis to Ampio in the amount of $8,000,000; and (iii) cancellation of indebtedness of Vyrix to Ampio in the amount of $4,000,000.

In January 2013, Luoxis entered into a services agreement with Ampio whereby Ampio provides corporate overhead services and a shared facility with Luoxis in exchange for $15,000 per month. The amount can be modified in writing upon the consent of both parties. The agreement may be terminated at any time by either party. In January 2014, Vyrix entered into a services agreement with Ampio whereby Ampio provides corporate overhead services to Vyrix in exchange for $7,000 per month. The amount can be modified in writing upon the consent of both parties. The agreement may be terminated at any time by either party. Both agreements were assigned to us upon the closing of the Merger.

In July 2015, Aytu entered into agreements with Ampio whereby Aytu agreed to pay Ampio $30,000 per month for shared overhead which includes costs related to the shared facility, corporate staff, and other miscellaneous overhead expenses. These agreements will be in effect until they are terminated in writing by both parties.

In June 2013, Luoxis entered into a sponsored research agreement with TRLLC, an entity controlled by Ampio’s director and Chief Scientific Officer, Dr. Bar-Or. The agreement, which was amended in September 2013 and provides for Luoxis to pay $6,000 per month to TRLLC in consideration for services related to research and development of Luoxis’ RedoxSYS System. In March 2014, Luoxis also agreed to pay a sum of $615,000 which is being amortized over the contractual term of 60.5 months and is divided between current and long-term on the balance sheet; this amount has been paid in full. This agreement is set to expire March 2019 and cannot be terminated prior to March 2017.

Due to the small size of our company, we do not at this time have a formal written policy regarding the review of related party transactions, and rely on our Board of Directors to review, approve or ratify such transactions and identify and prevent conflicts of interest. Our Board of Directors reviews any such transaction in light of the particular affiliation and interest of any involved director, officer or other employee or stockholder and, if applicable, any such person’s affiliates or immediate family members. Management aims to present transactions to our Board of Directors for approval before they are entered into or, if that is not possible, for ratification after the transaction has occurred. If our Board of Directors finds that a conflict of interest exists, then it will determine the appropriate action or remedial action, if any. Our Board of Directors approves or ratifies a transaction if it determines that the transaction is consistent with our best interests and the best interest of our stockholders.

Our common stock is not listed on any exchange. Consequently no exchange rules regarding director independence are applicable to us. Audit Committee members must satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, for listed companies. In order to be considered to be independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries.

Our sole director, Michael Macaluso, is not independent under the definition of either the NYSE or Nasdaq due to the payments we make to Ampio under the services agreements with Luoxis and Vyrix. However, even if our common stock was listed on either NYSE or Nasdaq, we would be exempt from the director independence rules (other than those applicable to audit committees) due to exemptions for listed companies that are “controlled companies,” which are companies of which more than 50% of the voting securities are held by one individual or entity. Because of Ampio beneficially owns 81.5% of our common stock, we would be a “controlled company.”

The following table set forth certain information regarding the selling stockholders and the shares of common stock beneficially owned by them, which information is available to us as of September 30, 2015. The selling stockholders may offer the shares under this prospectus from time to time and may elect to sell some, all or none of the shares set forth under this prospectus. However, for the purposes of the table below, we have assumed that, after completion of the offering, none of the shares covered by this prospectus will be held by the selling stockholders. In addition, a selling stockholder may have sold, transferred or otherwise disposed of all or a portion of that holder’s shares of common stock since the date on which the selling stockholder provided information for this table. We have not made independent inquiries about such transfers or dispositions. See the section entitled “Plan of Distribution” beginning on page 106.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Securities Exchange Act of 1934, or the Exchange Act. The percentage of shares beneficially owned prior to the offering is based on 14,259,681 shares of our common stock outstanding as of September 30, 2015. The shares in the table below, other than those owned by Ampio Pharmaceuticals, Inc., which are issued and outstanding, and Life Tech Capital/Newbridge Securities Corporation and Neidiger, Tucker, Bruner, Inc., which are shares issuable upon the exercise of warrants held by those two entities, are shares issuable upon the conversion of convertible notes.

Information about any other selling stockholders will be included in prospectus supplements or post-effective amendments, if required. Information about the selling stockholders may change from time to time. Any changed information with respect to which we are given notice will be included in prospectus supplements.

We are registering the shares of common stock offered in this prospectus on behalf of the selling stockholders. The term selling stockholders, which as used herein includes pledgees, donees, transferees or other successors-in-interest selling shares received from the selling stockholders as a gift, pledge, partnership distribution or other transfer after the date of this prospectus, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. The selling stockholders will pay any brokerage commissions and similar selling expenses attributable to the sale of the shares. We will not receive any of the proceeds from the sale of the shares by the selling stockholders.

These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. To the extent a selling stockholder gifts, pledges or otherwise transfers the shares offered hereby, such transferees may offer and sell the shares from time to time under this prospectus, provided that this prospectus has been amended under Rule 424(b)(3) or other applicable provision of the Securities Act to include the name of such transferee in the list of selling stockholders under this prospectus.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of common stock short and deliver these securities to close out its short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to a selling stockholder from the sale of the shares of common stock offered by it will be the purchase price of the common stock less discounts or commissions, if any. Each selling stockholder reserves the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents.

To the extent required, the shares of common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and its affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

The selling stockholders and any broker dealers that act in connection with the sale of the shares might be deemed to be “underwriters” as the term is defined in Section 2(11) of the Securities Act. Consequently, any commissions received by these broker dealers and any profit on the resale of the shares sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act. Because a selling stockholder may be deemed to be an “underwriter” as defined in Section 2(11) of the Securities Act, the selling stockholders may be subject to the prospectus delivery requirements of the Securities Act.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that such sale meets the criteria and conform to the requirements of that Rule.

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. No such broker-dealer will receive compensation in excess of that permitted by NASD Rule 2440 and IM-2440. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by the selling stockholders. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that agent, dealer or broker-dealer under the Securities Act.

The following table sets forth information with respect to the beneficial ownership of our common stock as of September 30, 2015 for:

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities and include common stock that can be acquired within 60 days of September 30, 2015. The percentage ownership information shown in the table is based upon 14,259,681 shares of common stock outstanding as of September 30, 2015.

Except as otherwise indicated, all of the shares reflected in the table are shares of common stock and all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information is not necessarily indicative of beneficial ownership for any other purpose.

In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of common stock subject to options and warrants held by that person that are immediately exercisable or exercisable within 60 days of September 30, 2015. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. Beneficial ownership representing less than 1% is denoted with an asterisk (*). The information in the table below is based on information known to us or ascertained by us from public filings made by the stockholders. Except as otherwise indicated in the table below, addresses of the director, executive officers and named beneficial owners are in care of Aytu BioScience, Inc., 373 Inverness Parkway, Suite 206, Englewood, Colorado 80112.

We are authorized to issue up to 300,000,000 shares of common stock, $0.0001 par value per share, and 50,000,000 shares of preferred stock, $0.0001 par value per share.

As of September 30, 2015, a total of 14,259,681 shares of our common stock were issued and outstanding and no shares of our preferred stock were issued and outstanding.

The holders of common stock are entitled to one vote per share. Our Certificate of Incorporation does not expressly prohibit cumulative voting. The holders of our common stock are entitled to receive ratably such dividends, if any, as may be declared by the Board of Directors out of legally available funds. Upon liquidation, dissolution or winding-up, the holders of our common stock are entitled to share ratably in all assets that are legally available for distribution. The holders of our common stock have no preemptive, subscription, redemption or conversion rights.

The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock, which may be designated solely by action of the Board of Directors and issued in the future.

Our Certificate of Incorporation provides our Board of Directors with the authority to divide the preferred stock into series and to fix and determine the rights and preferences of the shares of any series of preferred stock established to the full extent permitted by the laws of the State of Delaware and the Certificate of Incorporation.

As of September 30, 2015, we had outstanding warrants to purchase an aggregate of 160,653 shares of our common stock. Of these warrants, 102,613 were originally issued by Luoxis in 2013 and, in connection with the Merger, were converted into warrants to purchase shares of our common stock at a purchase price of $4.53 per share. These warrants expire on May 30, 2018.

The remaining 58,040 warrants to purchase shares of our common stock were issued to the placement agent in our private placement of convertible notes that we conducted in July and August 2015. These placement agent warrants have a term of five years, will have an exercise price equal to 100% of the price per share at which equity securities are sold in our next equity financing, and provide for cashless exercise.

Prior to the closing of the Merger, each of Vyrix and Luoxis had an option plan and had made equity grants thereunder. On April 16, 2015, upon the closing of the Merger, an aggregate of $27,476 was paid to holders of in-the-money options and all equity compensation plans of Vyrix and Luoxis were terminated and all the awards granted thereunder were cancelled.

On June 1, 2015, our stockholders approved the 2015 Stock Option and Incentive Plan, which provides for the award of stock options, stock appreciation rights, restricted stock and other equity awards for up to an aggregate of 10,000,000 shares of common stock. The shares of common stock underlying any awards that are forfeited, canceled, reacquired by us prior to vesting, satisfied without any issuance of stock, expire or are otherwise terminated (other than by exercise) under the 2015 Plan will be added back to the shares of common stock available for issuance under the 2015 Plan.

The 2015 Plan is administered by our Board or a committee designated by the Board (as applicable, the Administrator). The Administrator has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the 2015 Plan. The Administrator may

delegate to our Chief Executive Officer the authority to grant stock options and other awards to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act and not subject to Section 162(m) of the Code, subject to certain limitations and guidelines.

Persons eligible to participate in the 2015 Plan are full or part-time officers, employees, non-employee directors, directors and other key persons (including consultants and prospective officers) of our company and its subsidiaries as selected from time to time by the Administrator in its discretion. Approximately 25 individuals are currently eligible to participate in the 2015 Plan, which includes three officers, seven employees who are not officers, one non-employee director, and 12 other individuals who are primarily consultants.

The 2015 Plan provides that upon the effectiveness of a “sale event” as defined in the 2015 Plan, except as otherwise provided by the Administrator in the award agreement, all stock options, stock appreciation rights and other awards will be assumed or continued by the successor entity and adjusted accordingly to take into account the impact of the transaction. To the extent, however, that the parties to such sale event do not agree that all stock options, stock appreciation rights or any other awards shall be assumed or continued, then such stock options and stock appreciation rights shall become fully exercisable and the restrictions and conditions on all such other awards with time-based conditions will automatically be deemed waived. Awards with conditions and restrictions relating to the attainment of performance goals may become vested and non-forfeitable in connection with a sale event in the Administrator’s discretion. In addition, in the case of a sale event in which our stockholders will receive cash consideration, we may make or provide for a cash payment to participants holding options and stock appreciation rights equal to the difference between the per share cash consideration and the exercise price of the options or stock appreciation rights in exchange for the cancellation thereto.

The transfer agent of our common stock is Corporate Stock Transfer, Inc. Their address is 3200 Cherry Creek Drive South, Suite 430, Denver, CO 80209.

Delaware Anti-Takeover Law and Provisions of Our Certificate of Incorporation and Bylaws

Delaware Anti-Takeover Law. We are subject to Section 203 of the Delaware General Corporation Law. Section 203 generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

In general, Section 203 defines an “interested stockholder” as any person that is:

Under specific circumstances, Section 203 makes it more difficult for an “interested stockholder” to effect various business combinations with a corporation for a three-year period, although the stockholders may, by adopting an amendment to the corporation’s certificate of incorporation or bylaws, elect not to be governed by this section, effective 12 months after adoption.

Our certificate of incorporation and bylaws do not exclude us from the restrictions of Section 203. We anticipate that the provisions of Section 203 might encourage companies interested in acquiring us to negotiate in advance with our board of directors since the stockholder approval requirement would be avoided if a majority of the directors then in office approve either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder.

Certificate of Incorporation and Bylaw. Provisions of our certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change of control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, these provisions include:

The validity of the shares of common stock being offered by this prospectus will be passed upon for us by Wyrick Robbins Yates & Ponton, LLP, Raleigh, North Carolina.

The financial statements of Aytu BioScience, Inc. at June 30, 2015 and 2014, and for each of the two years in the period ended June 30, 2015, included in this prospectus and Registration Statement have been audited by EKS&H LLLP, independent registered public accounting firm, as set forth in their report thereon appearing elsewhere herein, and are included in reliance upon such report given on the authority of such firm as experts in accounting and auditing.

We have audited the accompanying balance sheets of Aytu Bioscience, Inc. (the “Company”) as of June 30, 2015 and 2014, and the related statements of operations, stockholders’ equity, and cash flows for each of the periods then ended. The Company’s management is responsible for these financial statements. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Aytu Bioscience, Inc. as of June 30, 2015 and 2014, and the results of its operations and its cash flows for each of the periods then ended, in conformity with accounting principles generally accepted in the United States of America.

Aytu BioScience, Inc. (“Aytu” or the “Company”) was incorporated as Rosewind Corporation on August 9, 2002 in the State of Colorado. Aytu was re-incorporated in the state of Delaware on June 8, 2015. Aytu is a specialty healthcare company concentrating on developing and commercializing products focused primarily on the urological disorders market, specifically sexual dysfunction, urological cancer and male infertility.

Aytu’s current business was formed through a reverse triangular merger (the “Merger”) in which Luoxis Diagnostics, Inc. (“Luoxis”) and Vyrix Pharmaceuticals, Inc. (“Vyrix”) merged into Rosewind Corporation in a multi-step merger on April 16, 2015. These historical financial statements prior to April 16, 2015 include the combined financial statements of Vyrix from its inception in November 2013, combined with the carve-out financial statements related to Vyrix assets acquired in the Merger (the “Vyrix Acquired Assets”) from March 23, 2011, the date, its parent company Ampio Pharmaceuticals, Inc. (“Ampio”) originally acquired the Vyrix Acquired Assets through its merger with DMI BioSciences, Inc. (“BioSciences”) and the financial statements of Luoxis from its inception in January 2013, combined with the carve-out financial statements related to Luoxis.

The carve-out financial statements present the statements of financial position of Vyrix and Luoxis and the Vyrix Acquired Assets and the statements of operations and cash flows for purposes of presenting complete comparative stand-alone financial statements in accordance with Regulation S-X, Article 3, General Instructions to Financial Statements, and Staff Accounting Bulletin Topic 1-B1, Costs Reflected in Historical Financial Statements. Historically, financial statements have not been prepared for Vyrix and Luoxis, as they were not held in a separate legal entities. Although Vyrix and Luoxis have not been segregated as a separate legal entity, related revenues, direct costs and expenses, assets and liabilities have historically been segregated on Ampio’s books. In addition, the Company allocated corporate overhead costs based on a review of specific labor and other overhead expenses and a reasonable estimate of activities related to Vyrix and Luoxis. Allocated labor and other overhead totaled $264,000 in 2015 and $253,000 in 2014. The Company also prepared a calculation of income tax expense and deferred income tax assets and liabilities on a “separate return” basis (see Note 4 – Income Taxes). These financial statements do not include a carve-out for cash as the operations have historically been funded by Ampio. The historical carve-out financial statements may not be indicative of the future results of Vyrix and Luoxis as a stand-alone entities.

The “Company” as referred to in the notes to these financial statements includes Vyrix and Luoxis, collectively.

The Company’s activities, being primarily research and development, have not generated significant revenue to date.

As of June 30, 2015, Ampio is the majority shareholder of 81.5% of Aytu’s outstanding common stock.

On June 8, 2015, in connection with the reincorporation as a Delaware corporation, we effected a reverse stock split in which each common stock holder received one share of common stock for each every 12.174 shares then outstanding (the “Reverse Stock Split”). All share and per share amounts in this Annual Report have been adjusted to reflect the effect of the Reverse Stock Split.

In May 2015, Aytu entered into and closed on an asset purchase agreement with Jazz Pharmaceuticals, Inc. (the “Seller”). Pursuant to the agreement, Aytu purchased assets related to the Seller’s product known as ProstaScint^® (capromab pendetide), including certain intellectual property and contracts, and the product approvals, inventory and work in progress (together, the “ProstaScint Business”), and assumed certain of the Seller’s liabilities, including those related to product approvals and the sale and marketing of ProstaScint.

The purchase price consists of the upfront payment of $1.0 million. Aytu also agreed to pay an additional $500,000 payable within five days after transfer for the ProstaScint-related product inventory and $227,000 payable on September 30, 2015 (which represents a portion of certain FDA fees). Aytu also will pay 8% as contingent consideration on its net sales made after October 31, 2017, payable up to a maximum aggregate payment of an additional $2.5 million. The contingent consideration was valued at $664,000 using a discounted cash flow. The total fair value consideration for the purchase was $2.4 million.

The Company’s allocation on consideration transferred for ProstaScint as of the purchase date May 20, 2015 is as follows:

The unaudited pro-forma results presented below include the effects of the ProstaScint acquisition as if it has been consummated as of July 1, 2013, with adjustments to give effect to pro forma events that are directly attributable to the acquisition which includes adjustments related to the amortization of acquired intangible assets. The unaudited pro forma results do not reflect any operating efficiency or potential cost savings which may result from the consolidation of ProstaScint. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operation of the combined company would have been if the acquisition had occurred at the beginning of the period presented nor are they indicative of future results of operations and are not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been consummated as of July 1, 2013.

Aytu considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of money market fund investments. Aytu’s investment policy is to preserve principal and maintain liquidity. The Company periodically monitors its positions with, and the credit quality of the financial institutions with which it invests. Periodically, throughout the year, Aytu has maintained balances in excess of federally insured limits.

Payments received upon signing of license agreements are for the right to use the license and are deferred and amortized over the lesser of the license term or patent life of the licensed drug. Milestone payments relate to obtaining regulatory approval, cumulative sales targets, and other projected milestones and are recognized at the time the milestones are achieved. Royalties will be recognized as revenue when earned.

Aytu recognizes revenue from product and service sales when there is persuasive evidence that an arrangement exists, delivery has occurred or service has been rendered, the price is fixed or determinable and collectability is reasonably assured.

Aytu records estimated reductions in revenue for potential returns of products by customers. As a result, management must make estimates of potential future product returns and other allowances related to current period product revenue. In making such estimates, management analyzes historical returns, current economic trends and changes in customer demand and acceptance of our products. If management were to make different judgments or utilize different estimates, material differences in the amount of the Company’s reported revenue could result.

Accounts receivable are recorded at their net realized value. Aytu evaluates collectability of accounts receivable on a quarterly basis and records a valuation allowance accordingly. As of June 30, 2015 and 2014, no allowance for doubtful accounts has been recorded.

Inventories are recorded at the lower of cost or market, with cost determined on a first-in, first-out basis. Aytu periodically reviews the composition of its inventories in order to identify obsolete, slow-moving or otherwise unsaleable items. If unsaleable items are observed and there are no alternate uses for the inventory, Aytu will record a write-down to net realizable value in the period that the impairment is first recognized.

When future commercialization is considered probable and the future economic benefit is expected to be realized, based on management’s judgment, Aytu capitalizes pre-launch inventory costs prior to regulatory approval. A number of factors are taken into consideration, including the current status in the regulatory approval process, potential impediments to the approval process, such as safety or efficacy, anticipated research and development initiatives that could impact the indication in which the compound will be used, viability of commercialization and marketplace trends. For product candidates that have not been approved by the FDA, inventory used in clinical trials is expensed at the time of production and recorded as research and development expense. For products that have been approved by the FDA, inventory used in clinical trials is expensed at the time the inventory is packaged for the clinical trial. Prior to receiving FDA approval, costs related to purchases of the active pharmaceutical ingredient and the manufacturing of the product candidate are recorded as research and development expense.

Fixed assets are recorded at cost. After being placed in service, the fixed assets are depreciated using the straight-line method over estimated useful lives. Fixed assets consist of the following:

In-process research and development (“IPRD”) relates to the Company’s Zertane product and clinical trial data acquired in connection with the 2011 acquisition of BioSciences. The $7,500,000 recorded was based on an independent, third party appraisal of the fair value of the assets acquired. IPRD is considered an indefinite-lived intangible asset and its fair value will be assessed annually and written down if impaired. Once the Zertane product obtains regulatory approval and commercial production begins, IPRD will be reclassified to an intangible that will be amortized over its estimated useful life. If the Company decided to abandon the Zertane product, the IPRD would be expensed.

Costs of establishing patents, consisting of legal and filing fees paid to third parties, are expensed as incurred. The fair value of the Zertane patents, determined by an independent third party appraisal, is $500,000. The Zertane patents were acquired in connection with the 2011 acquisition of BioSciences and are being amortized over the remaining U.S. patent lives of approximately 11 years which expires in March 2022. The cost of the Luoxis patents was $380,000 when they were acquired in connection with the 2013 formation of Luoxis and is being amortized over the remaining U.S. patent lives of approximately 15 years which expires in March 2028. Patents consist of the following:

The Company accounts for its business acquisitions under the acquisition method of accounting as indicated in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 805, “Business Combinations”, which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquire; and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities and non-controlling interest in the acquiree, based on the fair value estimates as of the date of acquisition. In accordance with ASC 805, the Company recognizes and measures goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired.

The ProstaScint purchase price allocation was based upon an analysis of the fair value of the assets and liabilities acquired from Jazz Pharmaceuticals. The final purchase price may be adjusted up to one year from the date of the acquisition. Identifying the fair value of the tangible and intangible assets and liabilities acquired required the use of estimates by management, and were based upon currently available data, as noted below.

The Company allocated the excess of purchase price over the identifiable intangible and net tangible assets to goodwill. Such goodwill is not deductible for tax purposes and represents the value placed on entering new markets and expanding market share.

The Company tests its goodwill for impairment annually, or whenever events or changes in circumstances indicate an impairment may have occurred, by comparing the carrying value to its implied fair value. Impairment may result from, among other things, deterioration in the performance of the acquired business, adverse market conditions, adverse changes in applicable laws or regulations and a variety of other circumstances. If the Company determines that an impairment has occurred, it is required to record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. In evaluating the recoverability of the carrying value of goodwill, the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the acquired assets. Changes in strategy or market conditions could significantly impact those judgments in the future and require an adjustment to the recorded balances. The goodwill was recorded as part of the acquisition of ProstaScint that occurred on May 20, 2015. There was no impairment of goodwill for the year ended June 30, 2015.

Aytu is included in the consolidated tax returns of Ampio. Aytu’s taxes are computed and reported on a “separate return” basis for these financial statements. Deferred taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carry forwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The amount of income taxes and related income tax positions taken would be subject to audits by federal and state tax authorities if Aytu filed these taxes on a separate basis. The Company has adopted accounting guidance for uncertain tax positions which provides that in order to recognize an uncertain tax benefit, the taxpayer must be more likely than not of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more than 50% likely to be realized upon settlement with the taxing authority. The Company believes that it has no material uncertain tax positions. The Company’s policy is to record a liability for the difference between the benefits that are both recognized and measured pursuant to FASB ASC 740-10, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109” (“ASC 740-10”) and tax position taken or expected to be taken on the tax return. Then, to the extent that the assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. The Company reports tax-related interest and penalties as a component of income tax expense. During the periods reported, management of the Company has concluded that no significant tax position requires recognition under ASC 740-10.

Aytu accounts for share based payments by recognizing compensation expense based upon the estimated fair value of the awards on the date of grant. The Company determines the estimated grant fair value using the Black-Scholes option pricing model and recognizes compensation costs ratably over the period of service using the graded method.

Research and development costs are expensed as incurred with expenses recorded in the respective period.

In June 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-10, “Technical Corrections and Improvements”. The amendments represent changes to clarify the codification, correct unintended application of guidance, or make minor improvements to the codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost. In addition, some of the amendments will make the codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the codification. The amendments that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon issuance. The Company is evaluating the impact of ASU 2015-10 on its financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued. The Company is evaluating the impact of ASU 2015-03 on its financial statements.

In January 2015, the FASB issued ASU 2015-01, “Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The purpose of this amendment is to eliminate the concept of extraordinary items. As a result, an entity will no longer be required to separately classify, present and disclose extraordinary events and transactions. The amendment is effective for annual reporting periods beginning after December 15, 2015 and subsequent interim periods with early application permitted. The Company is evaluating the impact the adoption of ASU 2015-01 will have on its financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the impact the adoption of ASU 2014-15 will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, “Revenue from Contracts with Customers”. The standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance will be effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted but not prior to the original public organization effective date of December 15, 2016. The Company is evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

During 2011, Ampio entered into a license, development and commercialization agreement with a major Korean pharmaceutical company which was assigned to Vyrix when it was formed in 2013. The agreement grants the pharmaceutical company exclusive rights to market Zertane in South Korea for the treatment of premature ejaculation (“PE”) and for a combination drug to be developed, utilizing Zertane and an erectile dysfunction drug. Upon signing of the agreement, Ampio received a $500,000 upfront payment, the net proceeds of which were $418,000 after withholding of Korean tax. The upfront payment has been deferred and is being recognized as license revenue over a ten year period. Milestone payments of $3,200,000 may be earned and recognized contingent upon achievement of regulatory approvals and cumulative net sales targets, which may take several years. In addition, Aytu may earn a royalty based on 25% of net sales, as defined, if the royalty exceeds the transfer price of the Zertane product. No royalties have been earned to date.

In April 2014, Vyrix entered into a Distribution and License Agreement (the “Paladin Agreement”) with Endo Ventures Limited, which recently acquired Paladin Labs Inc. (“Paladin”), whereby Paladin has exclusive rights to market, sell and distribute Zertane in Canada, the Republic of South Africa, certain countries in Sub Saharan Africa, Colombia and Latin America. The Paladin Agreement expires on a country by country basis upon the later of fifteen years after the first commercial sale of the product in that country or expiration of market exclusivity for Zertane in that country. Paladin paid $250,000 to Vyrix upon signing the Paladin Agreement and is obligated to make milestone payments aggregating up to $3,025,000 based upon achieving Canadian and South African product regulatory approval and achieving specific sales goals. The upfront payment has been deferred and is being recognized as license revenue over a seven year period. In addition, the Paladin Agreement provides that Paladin pay royalties based on sales volume.

As previously discussed in Note 2 – Summary of Significant Accounting Policies, the Company is included in Ampio’s consolidated tax returns. For purposes of these financial statements, the Company’s taxes are computed and reported on a “separate return” basis. Ampio and Aytu do not have a tax sharing agreement. Accordingly, certain tax attributes, e.g., net operating loss carryforwards, reflected in these financial statements, may or may not be available to Aytu. In the event that Ampio’s ownership interest in Aytu falls below 80% and Aytu is deconsolidated from Ampio’s consolidated income tax return, the net operating loss carryforwards originated prior to the incorporation of Vyrix and Luoxis would no longer be available to Aytu and the related deferred income tax asset would be removed and recorded as a deemed dividend to the parent, Ampio.

Income tax benefit resulting from applying statutory rates in jurisdictions in which Aytu is taxed (Federal and State of Colorado) differs from the income tax provision (benefit) in the Aytu’s financial statements. The following table reflects the reconciliation for the respective periods:

Deferred income taxes arise from temporary differences in the recognition of certain items for income tax and financial reporting purposes. The approximate tax effects of significant temporary differences which comprise the deferred tax assets and liabilities are as follows for the respective periods:

Aytu has recorded income tax benefits in its statements of operations since inception, stemming from its operating losses, and is expected to incur operating losses for the foreseeable future. During the year ended June 30, 2015, the net deferred tax liability was reduced to zero based upon the operating losses, thus Aytu established a valuation allowance offsetting any future net deferred tax asset. As such, Aytu would no longer record income tax benefits in its results of operations after the year ended June 30, 2015 because management is currently unable to conclude that it is more likely than not that a benefit will be realized.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, carry back opportunities and tax planning strategies in making the assessment. The Company believes it is more likely than not it will realize the benefits of these deductible differences, net of the valuation allowance provided.

The Company has federal net operating loss carryforwards of approximately $17.1 million and $10.4 million as of June 30, 2015 and June 30, 2014, respectively that, subject to limitation, may be available in future tax years to offset taxable income. The available net operating losses, if not utilized to offset taxable income in future periods, will begin to expire in 2031 through 2034. Net operating loss carryforwards are subject to examination in the year they are utilized regardless of whether the tax year in which they are generated has been closed by statute. The amount subject to disallowance is limited to the NOL utilized. Accordingly, the Company may be subject to examination for prior NOLs generated as such NOLs are utilized.

As of June 30, 2015 and 2014, the Company has no liability for gross unrecognized tax benefits or related interest and penalties.

Aytu has made its best estimates of certain income tax amounts included in the financial statements. Application of the Company’s accounting policies and estimates, however, involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, could differ from these estimates. In arriving at its estimates, factors the Company considers include how accurate the estimates or assumptions have been in the past, how much the estimates or assumptions have changed and how reasonably likely such changes may have a material impact. Aytu has been historically included in the Ampio consolidated tax return. Under the general statute of limitations, the Company would not be subject to federal or Colorado income tax examinations for years prior to 2011 and 2010, respectively. However, given the net operating losses generated since inception, all tax years since inception are subject to examination.

Commitments and contingencies are described below and summarized by the following table as of June 30, 2014:

Aytu is obligated to pay $500,000 for the ProstaScint-related product inventory upon the inventory transfer in July 2015.

Aytu entered into a Sponsored Research Agreement with Trauma Research LLC (“TRLLC”), a related party, in June 2013. Under the terms of the Sponsored Research Agreement, TRLLC agreed to work collaboratively in advancing the RedoxSYS System diagnostic platform through research and development efforts. The Sponsored Research Agreement may be terminated without cause by either party on 30 days’ notice.

In connection with the Zertane clinical trials and RedoxSYS research studies, the remaining commitment is $329,000.

Aytu entered into agreements with manufacturing companies to build its RedoxSYS system. The current remaining commitment is $133,000.

In June 2015, Aytu entered into a 37 month operating lease. This lease has initial base rent of $2,900 a month, with total base rent over the term of the lease of approximately $112,000. The Company recognizes rental expense of the facility on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent. Rent expense for the respective periods is as follows:

At June 30, 2015 and 2014, Aytu had 300 million shares of common stock authorized with a par value of $0.0001 per share and 50 million shares of preferred stock authorized with a par value of $0.0001 per share.

Prior to the Merger, Aytu had two approved stock option plans (Luoxis 2013 Stock Option Plan and Vyrix 2013 Stock Option Plan), pursuant to which Aytu had reserved a total of 1,718,828 million shares of common stock, both of which were terminated on April 16, 2015 upon the closing of the Merger.

The Luoxis options that were in the money and all outstanding Vyrix options issued under the 2013 Option Plans were accelerated and cancelled in connection with the Merger. Option holders received a cash payment per option share equal to the difference between the consideration payable per share of common stock pursuant to the Merger and the exercise price of the option, if the consideration paid to holders of common stock was less than the exercise price of such options, no amount was paid to the option holder in connection with the cancellation. The cash payment during the period ended June 30, 2015 was $27,000. The company recognized compensation of $422,000 and $189,000 related to the Luoxis and Vyrix options that had accelerated vesting as of the Merger date.

The Luoxis options that were not paid out were terminated pursuant to the terms of the 2013 Luoxis Option Plan. The Company treated these options as pre-vesting forfeitures and $433,000 of previously recognized compensation was reversed.

Pursuant to the Luoxis 2013 Stock Option Plan, 1,102,761 shares of its common stock were reserved for issuance. The fair value of the options was calculated using the Black-Scholes option pricing model. In order to calculate the fair value of the options, certain assumptions are made regarding components of the model, including the estimated fair value of the underlying common stock, risk-free interest rate, volatility, expected dividend yield and expected option life. Changes to the assumptions could cause significant adjustments to valuation. Aytu estimates the expected term based on the average of the vesting term and the contractual term of the options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity. The assumptions are as follows:

Pursuant to the Vyrix 2013 Stock Option Plan, 616,067 shares of its common stock were reserved for issuance. The fair value of the options was calculated using the Black-Scholes option pricing model. In order to calculate the fair value of the options, certain assumptions are made regarding components of the model, including the estimated fair value of the underlying common stock, risk-free interest rate, volatility, expected dividend yield and expected option life. Changes to the assumptions could cause significant adjustments to valuation. Aytu estimates the expected term based on the average of the vesting term and the contractual term of the options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity. In accordance with the Vyrix 2013 Stock Option Plan, no additional options were granted during the year-ended June 30, 2015. The assumptions are as follows:

Stock-based compensation expense related to the fair value of stock options was included in the statements of operations as research and development expenses and general and administrative expenses as set forth in the table below. Aytu determined the fair value as of the date of grant using the Black-Scholes option pricing model and expenses the fair value ratably over the vesting period. The following table summarizes stock-based compensation expense for the years ended June 30 2015 and 2014:

On June 1, 2015, Aytu’s stockholders approved the 2015 Stock Option and Incentive Plan (the “2015 Plan”), which provides for the award of stock options, stock appreciation rights, restricted stock and other equity awards for up to an aggregate of 10,000,000 shares of common stock. The shares of common stock underlying any awards that are forfeited, canceled, reacquired by Aytu prior to vesting, satisfied without any issuance of stock, expire or are otherwise terminated (other than by exercise) under the 2015 Plan will be added back to the shares of common stock available for issuance under the 2015 Plan. As of September 28, 2015, no grants have been made under the 2015 Plan.

Aytu issued warrants in conjunction with its 2013 private placement. A summary of all warrants is as follows:

These warrants were valued using the Black-Scholes option pricing model. In order to calculate the fair value of the warrants, certain assumptions were made regarding components of the model, including the closing price of the underlying common stock, risk-free interest rate, volatility, expected dividend yield, and expected life. Changes to the assumptions could cause significant adjustments to valuation. The Company estimated a volatility factor utilizing a weighted average of comparable published volatilities of peer companies. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity. The offering costs and the additional paid-in capital for the warrants associated with the common stock offering were valued at $313,000 using the Black-Scholes valuation methodology.

In November 2013, Vyrix entered into a loan agreement with Ampio. Pursuant to the loan agreement, Ampio agreed to lend Vyrix up to an aggregate amount of $3,000,000 through cash advances of up to $500,000 each. Unpaid principal amounts under the loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Vyrix may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Vyrix common stock at the fair market value per share of Vyrix common stock, as determined by the Ampio board of directors, as of such conversion date. As of June 30, 2014, the amount advanced was $1,600,000 with interest rates from 3.11%-3.32%. On April 16, 2015, in connection with the closing of the Merger, Ampio released Vyrix from its then outstanding obligation of $4,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

In March 2014, Luoxis entered into a loan agreement with Ampio. Pursuant to the loan agreement, Ampio agreed to lend Luoxis $3,000,000. Unpaid principal amounts under the loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Luoxis may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Luoxis common stock at the fair market value per share of Luoxis common stock, as determined by the Ampio board of directors, as of such conversion date. As of June 30, 2014, the amount advanced was $3,000,000 with interest rates from 3.11% - 3.32%. On April 16, 2015, in connection with the closing of the Merger, Ampio released Luoxis from its then outstanding obligation of $8,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

In June 2013, Luoxis entered into a sponsored research agreement with TRLLC, an entity controlled by Ampio’s director and Chief Scientific Officer, Dr. Bar-Or. The agreement, which was amended in January 2015 and provides for Luoxis (now Aytu) to pay $6,000 per month to TRLLC in consideration for services related to research and development of the Oxidation Reduction Potential platform. In March 2014, Luoxis also agreed to pay a sum of $615,000 which is being amortized over the contractual term of 60.5 months and is divided between current and long-term on the balance sheet; this amount has been paid in full. This agreement is set to expire March 2019 and cannot be terminated prior to March 2017.

As of June 30, 2015, Aytu was not party to any legal matters or claims, and none of its property is subject to any legal proceedings. In the future Aytu may become party to legal matters and claims arising in the ordinary course of business, the resolution of which it does not anticipate would have a material adverse impact on its financial position, results of operations or cash flows.

Aytu allows its employees to participate in Ampio’s 401(k) plan. The plan allows participants to contribute a portion of their salary, subject to eligibility requirements and annual IRS limits. Aytu does not match employee contributions.

During July and August 2015, Aytu closed on note purchase agreements with institutional and high net worth individual investors for the purchase and sale of convertible promissory notes with an aggregate principal amount of $5.2 million. The sale of the notes was pursuant to a private placement.

Aytu intends to use the net proceeds of the offering to conduct clinical studies for both Zertane® and RedoxSYS™ and for working capital to begin commercializing FDA-approved ProstaScint®, as well as general corporate purposes.

The notes are an unsecured obligation. Unless earlier converted, the notes will mature 18 months from their respective dates of issuance which will be on January 22, February 11 and February 28, 2017, with an option to extend up to six months at our discretion (provided that in the event Aytu exercises such extension option, the then applicable interest rate shall increase by 2% for such extension period). Aytu does not have the right to prepay the notes prior to the maturity date. Interest will accrue on the notes in the following amounts: (i) 8% simple interest per annum for the first six months and (ii) 12% simple interest per annum thereafter if not converted during the first six months. If there has not been a registration statement on Form S-1 filed with the SEC for the registration of the shares of common stock underlying the notes by the expiration of the first six-month period then (a) the interest rate will increase to 14% for the remainder of the period in which the notes remain outstanding and (b) any notes held by officers and directors of the Company will be subordinated to the remaining notes. Interest will accrue, is payable with the principal upon maturity, conversion or acceleration of the notes and may be paid in kind or in cash, in Aytu’s sole discretion.

The notes are convertible at any time in a noteholder’s discretion into that number of shares of Aytu common stock equal in an amount equal to 120% of the number of shares of common stock calculated by dividing the then outstanding principal and accrued interest by $4.63. A holder of notes will be obligated to convert on the terms of Aytu’s next public offering of its stock resulting in proceeds to it of at least $5,000,000 in gross proceeds (excluding indebtedness converted in such financing) prior to the maturity date of the notes (a “Qualified Financing”). The principal and accrued interest under the notes will automatically convert into a number of shares of such equity securities of the Company sold in such financing equal to 120% of the principal and accrued interest under such note divided by the lesser of (i) the lowest price paid by an investor in such financing or (ii) $4.63. In the event that Aytu

sells equity securities to investors at any time while the notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such financing into a number of shares of Aytu capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (i) the lowest cash price per share paid by purchasers of shares in such financing, or (ii) $4.63.

NewBridge Securities Corporation, Member FINRA/SIPC, through LifeTech Capital, acted as sole placement agent for the institutional portion of the offering. Aytu sold the balance of the notes to individuals and entities with whom Aytu has an established relationship. For notes sold by the placement agent, Aytu paid the placement agent 8% of the gross proceeds of notes sold by the placement agent and a warrant to purchase shares of Aytu’s common stock equal to 8% of the gross proceeds of the notes sold by the placement agent divided by the price per share at which equity securities are sold in Aytu’s next equity financing, in addition to a previously paid non-refundable retainer fee of $20,000. The placement agent warrant has a term of five years, will have an exercise price equal to 100% of the price per share at which equity securities are sold in Aytu’s next equity financing, and provides for cashless exercise.

On August 19, 2015, Aytu entered into a 37 month non-cancellable operating lease for new office space effective September 1, 2015. The new lease has initial base rent of $8,500 per month beginning in October 2015, with the total base rent over the term of the lease of approximately $318,000 which includes rent abatements. The Company recognizes rental expense of the facility on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent.

On October 5, 2015, the Company entered into and closed on an Asset Purchase Agreement with FSC Laboratories, Inc. (the “Seller”). Pursuant to the agreement, the Company purchased assets related to the Seller’s product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in progress and all marketing and sales assets and materials related solely to Primsol (together, the “Primsol Business”), and assumed certain of the Seller’s liabilities, including those related to the sale and marketing of Primsol arising after the closing. The agreement provides that for a period of one year after the closing the Seller will not directly or indirectly sell, market, promote, advertise or distribute anywhere in the world any urinary tract anti-infective pharmaceutical or treatment product containing trimethoprim.

The Company paid $500,000 at closing for the Primsol Business and agreed to pay an additional $141,694 payable within five days after transfer of the Primsol-related product inventory. The Company also agreed to pay an additional (a) $500,000 payable no later than March 31, 2016, (b) $500,000 payable no later than June 30, 2016, and (c) $250,000 payable no later than September 30, 2016, for a total purchase price of $1,891,694.

On October 8, 2015, the Company and Biovest International, Inc. (“Biovest”) entered into a Master Services Agreement, pursuant to which Biovest is to provide manufacturing services to the Company. The agreement provides that the Company may engage Biovest from time to time to provide services in accordance with mutually agreed upon project addendums and purchase orders. The Company expects to use the agreement from time to time for manufacturing services, including without limitation, the manufacturing, processing, quality control testing, release or storage of its products. The agreement has a term of four years, provided that either party may terminate the agreement or any project addendum under the agreement on 30 days written notice of a material breach under the agreement. In addition, the Company may terminate the agreement or any project addendum under the agreement upon 180 days written notice for any reason. In conjunction with entering into the agreement, the Company submitted a work order to Biovest to provide the Company with active pharmaceutical ingredient for ProstaScint over a four-year period at a total cost of $5,000,000, of which the Company paid $1,000,000 upon submission of the work order.

Historically, financial statements have not been prepared for Vyrix and Luoxis, as they were not held in a separate legal entity. Although Vyrix and Luoxis have not been segregated as a separate legal entity, related revenues, direct costs and expenses, assets and liabilities have historically been segregated on Ampio’s books. In addition, the Company allocated corporate overhead costs based on a review of specific labor and other overhead expenses and a reasonable estimate of activities related to Vyrix and Luoxis. Allocated labor and other overhead totaled $264,000 in 2015 and $253,000 in 2014. The Company also prepared a calculation of income tax expense and deferred income tax assets and liabilities on a “separate return” basis. These financial statements do not include a carve-out for cash as the operations have historically been funded by Ampio. The historical carve-out financial statements may not be indicative of the future results of Vyrix and Luoxis as a stand-alone entity.

The “Company” as referred to in the notes to these financial statements includes Vyrix and Luoxis, collectively.

As of September 30, 2015, Ampio is the majority shareholder of 81.5% of Aytu’s outstanding common stock.

On June 8, 2015, in connection with the reincorporation as a Delaware corporation, the Company effected a reverse stock split in which each common stock holder received one share of common stock for each every 12.174 shares then outstanding (the “Reverse Stock Split”). All share and per share amounts in this Report have been adjusted to reflect the effect of the Reverse Stock Split.

including certain intellectual property and contracts, and the product approvals, inventory and work in progress (together, the “ProstaScint Business”), and assumed certain of the Seller’s liabilities, including those related to product approvals and the sale and marketing of ProstaScint.

The purchase price consisted of the upfront payment of $1.0 million. Aytu also agreed to pay an additional $500,000 payable within five days after transfer for the ProstaScint-related product inventory and $227,000 that was paid subsequent to September 30, 2015 (which represents a portion of certain FDA fees). Aytu also will pay 8% as contingent consideration on its net sales made after October 31, 2017, payable up to a maximum aggregate payment of an additional $2.5 million. The contingent consideration was valued at $664,000 using a discounted cash flow estimate as of the acquisition date. The total fair value consideration for the purchase was $2.4 million.

The Company’s allocation on consideration transferred for ProstaScint as of the purchase date of May 20, 2015 is as follows:

Included in the intangible assets is Developed technology of $790,000, Customer contracts of $720,000 and Trade names of $80,000, each of which will be amortized over a ten-year period.

As of September 30, 2015 the contingent consideration had increased to $677,000 due to accretion.

In September 2015, the Financial Accounting Standards Board, (“FASB”) issued Accounting Standards Update (“ASU”) 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments,” which requires that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendment is effective for financial statements issued for fiscal years beginning after December 15, 2015 and early adoption is permitted. As of September 30, 2015, the Company early adopted this standard.

In July 2015, the FASB issued ASU 2015-12, “Plan Accounting: Defined Benefits Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962) and Health and Welfare Benefit Plans (Topic 965): I. Fully Benefit-Responsive Investment Contracts; II. Plan Investment Disclosures; and III. Measurement Date Practical Expedient.” This three-part ASU simplifies current benefit plan accounting and requires (i) fully benefit-responsive investment contracts to be measured, presented, and disclosed only at contract value and accordingly removes the requirement to reconcile their contract value to fair value; (ii) benefit plans to disaggregate their investments measured using fair value by general type, either on the face of the financial statements or in the notes to the financial statements; (iii) the net appreciation or depreciation in investments for the period to be presented in the aggregate rather than by general type, and removes certain disclosure requirements relevant to individual investments that represent five percent or more of net assets available for benefits. Further, the amendments in this ASU eliminate the requirement to disclose the investment strategy for certain investments that are measured using Net Asset Value (“NAV”) per share using the practical expedient in the FASB ASC Topic 820. Part III of the ASU provides a practical expedient to permit employee benefit plans to measure investments and investment-related accounts as of the month-end that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with a month-end, while requiring certain additional disclosures. The amendments in Parts I and II of this standard are effective retrospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. The amendments in Part III of this standard are effective prospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. The Company is currently evaluating the impact of this standard on its financial statements.

In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” ASU 2015-11 clarifies that inventory should be held at the lower of cost or net realizable value. Net realizable value is defined as the estimated selling price, less the estimated costs to complete, dispose and transport such inventory. ASU 2015-11 will be effective for fiscal years and interim periods beginning after December 15, 2016. ASU 2015-11 is required to be applied prospectively and early adoption is permitted. The adoption of ASU 2015-11 is not expected to have a material impact on the Company’s financial position or results of operations.

In June 2015, the FASB issued ASU 2015-10, “Technical Corrections and Improvements”. The amendments represent changes to clarify the codification, correct unintended application of guidance, or make minor improvements to the codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost. In addition, some of the amendments will make the codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the codification. The amendments that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon issuance. The Company is evaluating the impact of ASU 2015-10 on its financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” to simplify the presentation of debt issuance costs. The amendments in the update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction of the carrying amount of the debt. Recognition and measurement of debt issuance costs were not affected by this amendment. In August 2015, FASB issued ASU 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated With Line-of-Credit Arrangements – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting” which clarified that the SEC would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2015. As of September 30, 2015, the Company early adopted this standard and recorded debt issuance costs as a debt discount. There was no impact related to this adoption as the Company did not have any debt issuance costs previously.

In January 2015, the FASB issued ASU 2015-01, “Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The purpose of this amendment is to eliminate the concept of extraordinary items. As a result, an entity will no longer be required to separately classify, present and disclose extraordinary events and transactions. The amendment is effective for annual reporting periods beginning after December 15, 2015 and subsequent interim periods with early application permitted. The Company is evaluating the impact the adoption of ASU 2015-01 will have on its financial statements.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the impact the adoption of ASU 2014-15 will have on its financial statements.

In May 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, “Revenue from Contracts with Customers”. The standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. The Company is currently evaluating the effect that the updated standard will have on its financial statements.

Fixed assets are recorded at cost and, once placed in service, are depreciated on the straight-line method over the estimated useful lives. Fixed assets consist of the following:

In-process research and development (“IPRD”) relates to the Zertane product candidate. The $7,500,000 recorded was based on an independent, third party appraisal of the fair value of the assets acquired. IPRD is considered an indefinite-lived intangible asset and its fair value will be assessed annually and written down if impaired. If the Zertane product candidate obtains regulatory approval and commercial production begins, IPRD will be reclassified to an intangible that will be amortized over its estimated useful life. If the Company decides to abandon the Zertane product, the IPRD would be expensed.

Costs of establishing patents, consisting of legal and filing fees paid to third parties, are expensed as incurred. The fair value of the Zertane patents, determined by an independent, third party appraisal to be $500,000 is being amortized over the remaining U.S. patent lives of approximately 11 years. The cost of the ORP related patents was $380,000 when they were acquired and is being amortized over the remaining U.S. patent lives of approximately 15 years. Patents consist of the following:

The $466,000 and $6,000 product and service revenue recognized during the three months ended September 30, 2015 and 2014, respectively, represents sales of our ProstaScint product and the RedoxSYS System.

The license revenue recognized in the three months ended 2015 and 2014, respectively, represents the amortization of the upfront payments received from our license agreements. The initial payment of $500,000 from the license agreement of Zertane with a Korean pharmaceutical company was deferred and is being recognized over ten years. The initial payment of $250,000 from the license agreement of Zertane with a Canadian-based supplier was deferred and is being recognized over seven years.

Aytu’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, convertible promissory notes and warrant derivative liability. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short maturities. The fair value of the convertible notes is approximately the face value of the notes, $5,175,000 based upon the valuation that the Company had completed of all components of the convertible notes at inception and as of September 30, 2015. The valuation policies are determined by the Chief Financial Officer and approved by the Company’s Board of Directors as deemed appropriate.

Authoritative guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of Aytu. Unobservable inputs are inputs that reflect Aytu’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on reliability of the inputs as follows:

Aytu’s assets and liabilities which are measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Aytu’s policy is to recognize transfers in and/or out of fair value hierarchy as of the date in which the event or change in circumstances caused the transfer. Aytu has consistently applied the valuation techniques discussed below in all periods presented.

The following table presents Aytu’s financial liabilities that were accounted for at fair value on a recurring basis as of September 30, 2015, by level within the fair value hierarchy:

The warrant derivative liability for the warrants was valued using the Monte Carlo valuation methodology because that model embodies all of the relevant assumptions that address the features underlying these instruments. Significant assumptions in valuing the warrant derivative liability, based on estimates of the value of our common stock and various factors regarding the warrants, were as follows as of September 30, 2015 and at issuance:

The following table sets forth a reconciliation of changes in the fair value of financial liabilities classified as Level 3 in the fair valued hierarchy:

Commitments and contingencies are described below and summarized by the following table for the designated fiscal years ending June 30, as of September 30:

In June 2015, Aytu entered into a 37 month operating lease for a space in Raleigh, North Carolina. This lease has initial base rent of $2,900 a month, with total base rent over the term of the lease of approximately $112,000. In September 2015, the Company entered into a 37 month operating lease in Englewood, Colorado. This lease has an initial base rent of $8,500 a month with a total base rent over the term of the lease of approximately $318,000. The Company recognizes rental expense of the facilities on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent. Rent expense for the respective periods is as follows:

In connection with the Zertane clinical trials and RedoxSYS research studies, the remaining commitment is $266,000.

During July and August 2015, Aytu closed on note purchase agreements with institutional and high net worth individual investors for the purchase and sale of convertible promissory notes (“Notes”) with an aggregate principal amount of $5.2 million. The sale of the Notes was pursuant to a private placement. Debt issuance costs totaled $401,000 which includes $103,000 fair value of the warrants.

The Notes are an unsecured obligation. Unless earlier converted, the Notes will mature 18 months from their respective dates of issuance which will be on January 22, February 11 and February 28, 2017, with an option to extend the maturity date up to six months at Aytu’s discretion (provided that in the event Aytu exercises such extension option, the then applicable interest rate shall increase by 2% for such extension period). Aytu does not have the right to prepay the Notes prior to the maturity date. Interest will accrue on the Notes in the following amounts: (i) 8% simple interest per annum for the first six months and (ii) 12% simple interest per annum thereafter if not converted during the first six months. If there has not been a registration statement on Form S-1 filed with the SEC for the registration of the shares of common stock underlying the Notes by the expiration of the first six-month period then (a) the interest rate will increase to 14% for the remainder of the period in which the Notes remain outstanding and (b) any Notes held by officers and directors of the Company will be subordinated to the remaining Notes. Interest will accrue, is payable with the principal upon maturity, conversion or acceleration of the Notes and may be paid in kind or in cash, in Aytu’s sole discretion.

The 4% increase in the interest rate is triggered automatically with the passage of time and is not a contingent feature, thus, there is no initial accounting for this feature. However, the periodic interest cost will be calculated using a constant effective interest over the life of the Notes. As management does not intend to utilize the extension option, the expected life of the Notes is 18 months.

The Company did not give recognition to the registration rights arrangement as management did not believe at issuance that probable payment under the contingent escalation clause would be required, thus there was no impact on the initial measurement of the Notes. The Company satisfied the registration rights arrangement in October 2015 upon the effectiveness of a registration statement on Form S-1.

The Notes are convertible at any time at the noteholder’s discretion into that number of shares of Aytu common stock equal in an amount equal to 120% of the number of shares of common stock calculated by dividing the then outstanding principal and accrued interest by $4.63. A holder of Notes will be obligated to convert on the terms of Aytu’s next public offering of its stock resulting in gross proceeds of at least $5,000,000 (excluding indebtedness converted in such financing) prior to the maturity date of the Notes (a “Qualified Financing”). The principal and accrued interest under the Notes will automatically convert into a number of shares of such equity securities of the Company sold in the Qualified Financing equal to 120% of the principal and accrued interest under such Note divided by the lesser of (i) the lowest price paid by an investor in the Qualified Financing or (ii) $4.63. In the event that Aytu sells equity securities to investors at any time while the Notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such

financing into a number of shares of Aytu capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (i) the lowest cash price per share paid by purchasers of shares in such financing, or (ii) $4.63.

The Company determined that the conversion option is not required to be bifurcated and accounted for as an embedded derivative liability. There was no intrinsic value to the beneficial conversion feature as it was determined that the effective conversion price exceeded the commitment date valuation price.

The Notes contained a purchase premium option in the event of a sale transaction as defined in the Notes. A holder of the Notes will be entitled to receive, at the holder’s option, (i) repayment of the Note balance plus the amount equal to 25% of the original purchase amount or (ii) the consideration the holder would have received on an as-converted basis. Given that the payment under the purchase premium is contingent upon a sale transaction and involves a substantial premium of 25%, the purchase premium is an embedded derivative that must be bifurcated and accounted for as an embedded derivative. No value was recorded related to this derivative at issuance and September 30, 2015.

Newbridge Securities Corporation, a FINRA/SIPC member, through LifeTech Capital, acted as sole placement agent for the institutional portion of the offering of the Notes. Aytu sold the balance of the Notes to individuals and entities with whom Aytu has an established relationship. For Notes sold by the placement agent, Aytu paid the placement agent 8% of the gross proceeds of Notes sold by the placement agent and is obligated to issue warrants for an amount of shares to be equal to 8% of the gross number of shares of the Company stock issuable upon conversion of the Notes issued to investors introduced to the Company by the private placement agents in the private placement, in addition to a previously paid non-refundable retainer fee of $20,000. The placement agent warrant has a term of five years, will have an exercise price equal to the lowest conversion price per share at which the Notes are converted into common stock. Change in fair value is recorded in earnings. Fair value at the grant date was recorded as a debt discount and amortized over the term of the debt.

The warrants were recorded at fair value as long-term liabilities on the Balance Sheet. See Note 4.

Per our adoption of ASU 2015-3, the costs associated with the Notes were recorded as a long–term liability and are presented in the Balance Sheet as a direct reduction of the carrying amount of the Notes on their inception date.

As of September 30, 2015, the carrying value of the Notes was $4.8 million inclusive of an unamortized debt discount of $350,000.

At September 30, 2015 and June 30, 2015, Aytu had 300 million shares of common stock authorized with a par value of $0.0001 per share and 50 million shares of preferred stock authorized with a par value of $0.0001 per share.

The Luoxis options that were in the money and all outstanding Vyrix options issued under the respective 2013 Option Plans were accelerated and cancelled in connection with the Merger. Option holders received a cash payment per option share equal to the difference between the consideration payable per share of common stock pursuant to the Merger and the exercise price of the option; if the consideration paid to holders of common stock was less than the exercise price of such options, no amount was paid to the option holder in connection with the cancellation. The cash payment during the period ended June 30, 2015 was $27,000. The Company recognized compensation of $422,000 and $189,000 related to the Luoxis and Vyrix options that had accelerated vesting as of the Merger date during the period ended June 30, 2015.

be added back to the shares of common stock available for issuance under the 2015 Plan. The fair value of the options are calculated using the Black-Scholes option pricing model. In order to calculate the fair value of the options, certain assumptions are made regarding components of the model, including the estimated fair value of the underlying common stock, risk-free interest rate, volatility, expected dividend yield and expected option life. Changes to the assumptions could cause significant adjustments to valuation. Aytu estimates the expected term based on the average of the vesting term and the contractual term of the options. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of the grant for treasury securities of similar maturity. Aytu has computed the fair value of all options granted during the three months ended September 30, 2015 using the following assumptions:

Stock-based compensation expense related to the fair value of stock options was included in the statements of operations as research and development expenses and selling, general and administrative expenses as set forth in the table below. Aytu determined the fair value as of the date of grant using the Black-Scholes option pricing model and expenses the fair value ratably over the vesting period. The following table summarizes stock-based compensation expense for the three months ended September 30, 2015 and for the stock-based compensation expense related to the Luoxis and Vyrix options for the three months ended September 30, 2014:

Aytu issued warrants in conjunction with its 2013 private placement. A summary of these warrants is as follows:

Aytu has the obligation to issue warrants to the private placement agents as part of their fees for the convertible note financing. These warrants are classified as a derivative warrant liability due to the fact that the number of shares and exercise price have not been set as of September 30, 2015. The number of shares of Company stock that these warrants will convert into is equal to 8% of the gross number of shares of the Company stock issuable upon conversion of the Notes issued to investors introduced to the Company by the private placement agents pursuant to the private placement memorandum. The exercise price will be the lowest conversion price per share at which the Notes are converted into Company common stock. The warrants have a term of five years from August 31, 2015.

loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Vyrix may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Vyrix common stock at the fair market value per share of Vyrix common stock, as determined by the Ampio board of directors, as of such conversion date. As of June 30, 2014, the amount advanced was $1,600,000 with interest rates from 3.11%-3.32%. On April 16, 2015, in connection with the closing of the Merger, Ampio released Vyrix from its then outstanding obligation of $4,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

In March 2014, Luoxis entered into a loan agreement with Ampio. Pursuant to the loan agreement, Ampio agreed to lend Luoxis $3,000,000. Unpaid principal amounts under the loan agreement bear simple interest at the “Applicable Federal Rate” for long-term obligations prescribed under Section 1274(d) of the Internal Revenue Code of 1986, as amended (or any successor provision with similar applicability). The initial term of this loan agreement is for one year, subject to automatic extension of successive one-year terms. Luoxis may repay any outstanding balance at any time without penalty. Ampio has an option of converting any balance outstanding under the loan agreement into shares of Luoxis common stock at the fair market value per share of Luoxis common stock, as determined by the Ampio board of directors, as of such conversion date. As of June 30, 2014, the amount advanced was $3,000,000 with interest rates from 3.11% – 3.32%. On April 16, 2015, in connection with the closing of the Merger, Ampio released Luoxis from its then outstanding obligation of $8,000,000 under the loan agreement as consideration of its share purchase, and the loan agreement was terminated.

The Company has entered into a service agreement with Ampio which is described in Note 7.

In June 2013, Luoxis entered into a sponsored research agreement with TRLLC, an entity controlled by Ampio’s director and Chief Scientific Officer, Dr. Bar-Or. The agreement, which was amended in January 2015 and provides for Luoxis (now Aytu) to pay $6,000 per month to TRLLC in consideration for services related to research and development of the RedoxSYS platform. In March 2014, Luoxis also agreed to pay $615,000 which is being amortized over the contractual term of 60.5 months and is divided between current and long-term on the balance sheet; this amount has been paid in full. This agreement is set to expire March 2019 and cannot be terminated prior to March 2017.

The convertible promissory notes (see Note 8) include $275,000 invested by relatives of senior management of the Company.

On October 5, 2015, Aytu entered into and closed on an Asset Purchase Agreement with FSC Laboratories, Inc. (the “Seller”). Pursuant to the agreement, Aytu purchased assets related to the Seller’s product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in progress and all marketing and sales assets and materials related solely to Primsol (together, the “Primsol Business”), and assumed certain of the Seller’s liabilities, including those related to the sale and marketing of Primsol arising after the closing.

Aytu paid $500,000 at closing for the Primsol Business and also agreed to pay an additional $142,000 payable within five days after transfer of the Primsol-related product inventory. Aytu also agreed to pay an additional (a) $500,000 payable no later than March 31, 2016, (b) $500,000 payable no later than June 30, 2016, and (c) $250,000 payable no later than September 30, 2016 (together, the “Installment Payments”).

On October 8, 2015, Aytu entered into a Master Services Agreement with Biovest International, Inc. (“Biovest”). The agreement provides that Aytu may engage Biovest from time to time to provide services in accordance with mutually agreed upon project addendums and purchase orders. Aytu expects to use the agreement from time to time for manufacturing services, including without limitation, the manufacturing, processing, quality control testing, release or storage of its products.

The agreement provides customary terms and conditions, including those for performance of services by Biovest in compliance with project addendums, industry standards, regulatory standards and all applicable laws. Biovest will be responsible for obtaining and maintaining all governmental approvals, at our expense, during the term of the agreement.

The agreement has a term of four years, provided that either party may terminate the agreement or any project addendum under the agreement on 30 days written notice of a material breach under the agreement. In addition, Aytu may terminate the agreement or any project addendum under the agreement upon 180 days written notice for any reason.

In conjunction with entering into the agreement, Aytu submitted a work order to Biovest to provide Aytu with active pharmaceutical ingredient for ProstaScint over a four-year period at a total cost of $5,000,000, of which we paid $1,000,000 upon submission of the work order and anticipate paying the remaining balance as follows in fiscal:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion should be read in conjunction with Aytu BioScience, Inc.’s Form 10-K filed on September 28, 2015. The following discussion and analysis contains forward-looking statements that involve risks and uncertainties. Actual results could differ materially from those projected in the forward-looking statements. For additional information regarding these risks and uncertainties, please see Part II, Item 1A of this Form 10-Q, “Risk Factors” and the risk factors included in Aytu’s Form 10-K filed with the Securities and Exchange Commission on September 28, 2015.

On April 16, 2015, we completed the multi-step reverse triangular merger of Vyrix Pharmaceuticals, Inc. (“Vyrix”) and Luoxis Diagnostics, Inc. (“Luoxis”) into our Company (the “Merger”) and we abandoned our pre-merger business plans to solely pursue the specialty healthcare market, including the business of Vyrix and Luoxis. In May 2015, we closed on an asset purchase agreement with Jazz Pharmaceuticals, Inc., pursuant to which we purchased assets related to Jazz Pharmaceuticals’ product known as ProstaScint^® (capromab pendetide) (the “ProstaScint Business”), and assumed certain of Jazz Pharmaceuticals’ liabilities related to the ProstaScint Business.

During July and August 2015, Aytu issued in a private placement unsecured convertible promissory notes (“Notes”) with an aggregate principal amount of $5.2 million. We are also obligated to issue to the placement agents in the private placement, warrants for an amount of shares to be equal to 8% of the gross number of shares of our stock issuable upon conversion of the Notes issued to investors introduced to us by the private placement agents in the private placement. The placement agent warrants have a term of five years and will have an exercise price equal to the lowest conversion price per share at which the Notes are converted into our common stock.

In October 2015, we entered into and closed on an Asset Purchase Agreement with FSC Laboratories, Inc. (the “Seller”). Pursuant to the agreement, we purchased assets related to the Seller’s product known as Primsol^® (trimethoprim solution), including certain intellectual property and contracts, inventory, work in progress and all marketing and sales assets and materials related solely to Primsol (together, the “Primsol Business”), and assumed certain of the Seller’s liabilities, including those related to the sale and marketing of Primsol arising after the closing. We paid $500,000 at closing for the Primsol Business and we agreed to pay an additional $142,000 payable within five days after transfer of the Primsol-related product inventory. We also agreed to pay an additional (a) $500,000 payable no later than March 31, 2016, (b) $500,000 payable no later than June 30, 2016, and (c) $250,000 payable no later than September 30, 2016 (together, the “Installment Payments”). The accounting for this business combination is not yet complete and the amount assigned to the assets acquired is provisional because the final appraisal report has not been received at the time of this filing.

To date, we have financed operations through a combination of private and public debt and equity financings including the net proceeds from the private placement of stock as well as convertible notes. Although it is difficult to predict our liquidity requirements, based upon our current operating plan, we believe we will have sufficient cash to meet our projected operating requirements for at least the next 12 months. See “Liquidity and Capital Resources.”

We have only begun to generate revenues from the commercialization of our product candidates in the last few quarters. However, we have recognized limited revenue from ProstaScint sales. We have incurred accumulated net losses since our inception, and as of September 30, 2015, we had a deficit accumulated of $20.7 million. Our net loss was $2.3 million for the three months ended September 30, 2015 and $2.1 million for the three months ended September 30, 2014.

We continue to execute our business plan and continue to progress forward on the development of our novel diagnostic device, acquire marketed pharmaceutical products and assess options for advancing our drug development candidate.

In May 2015, we acquired ProstaScint from Jazz Pharmaceuticals. ProstaScint is the only commercially available diagnostic imaging agent approved by the U.S. Food and Drug Administration (“FDA”) that specifically targets prostate cancer cells that have spread to tissue outside of the prostate gland. ProstaScint was approved by the FDA in October 1996 and was initially commercialized by Cytogen which was acquired by EUSA Pharma and Jazz Pharmaceuticals acquired EUSA Pharma and its product portfolio including ProstaScint in 2012.

In October 2015 we acquired Primsol (trimethoprim hydrochloride) from FSC Laboratories, Inc. Primsol is the only FDA-approved trimethoprim-only oral solution and is standard therapy for urinary tract infections. Primsol is a sulfa-free, pleasant tasting liquid that is appropriate for patients that are sulfa allergic and individuals that have difficulty swallowing pills. Primsol was approved by the FDA in 2000 and was originally marketed by Ascent Pediatrics. FSC Laboratories acquired Primsol from Taro Pharmaceutical.

RedoxSYS is a novel, diagnostic platform comprised of a first-in-class, point-of-care device and disposable testing strips that together measure the presence of oxidative stress and antioxidant reserves. We believe this device could also be used as a key indicator in male reproductive health as a stand-alone application. Currently, the device is being studied in over 60 research collaborations that will continue through 2015. To date, the revenue related to the device and the test strips is not material.

We intend to leverage our RedoxSYS research tool to develop a clinical application – known as MiOXSYS – to assess oxidative stress levels in infertile males. Proof of concept studies in male infertility have been conducted with a leading center in the United States and determined that oxidation-reduction potential effectively measures oxidative stress levels in semen and seminal fluid. Semen analysis studies are routinely conducted to assess causes of infertility, so we expect clinicians and oxidative stress researchers to readily integrate MiOXSYS into routine use. Additional studies are now underway that will determine the MiOXSYS system’s performance in semen analysis as it relates to infertility.

Zertane is an oral drug subject to an open Investigational New Drug Application for a Phase 3 clinical trial for the treatment of premature ejaculation (“PE”). The FDA has accepted our Investigational New Drug application and a Phase 3 clinical study may now begin in the United States although we not have yet determined when this study will start.

Our financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of the financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments, including those related to recoverability of long-lived assets, stock compensation, valuation of derivative instruments, allowances and contingencies. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The methods, estimates, and judgments used by us in applying these most critical accounting policies have a significant impact on the results we report in our financial statements. Our significant accounting policies and estimates are included in our Form 10-K, filed with the SEC on September 28, 2015.

We account for financial instruments (convertible debt with embedded derivative features – conversion options and conversion provisions) and related warrants by recording the fair value of each instrument in its entirety and recording the fair value of the warrant derivative liability. The fair value of the financial instruments and related warrants was calculated using a Monte Carlo based valuation model. We recorded a derivative expense at the inception of the instrument reflecting the difference between the fair value and cash received. Changes in the fair value in subsequent periods will be recorded as unrealized gain or loss on fair value of debt instruments for the financial instruments and to derivative income or expense for the warrants.

In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments,” which require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendment is effective for financial statements issued for fiscal years beginning after December 15, 2015 and early adoption is permitted. As of September 30, 2015, we have early adopted this standard.

Contracts; II. Plan Investment Disclosures; and III. Measurement Date Practical Expedient.” This three-part ASU simplifies current benefit plan accounting and requires (i) fully benefit-responsive investment contracts to be measured, presented, and disclosed only at contract value and accordingly removes the requirement to reconcile their contract value to fair value; (ii) benefit plans to disaggregate their investments measured using fair value by general type, either on the face of the financial statements or in the notes to the financial statements; (iii) the net appreciation or depreciation in investments for the period to be presented in the aggregate rather than by general type, and removes certain disclosure requirements relevant to individual investments that represent five percent or more of net assets available for benefits. Further, the amendments in this ASU eliminate the requirement to disclose the investment strategy for certain investments that are measured using Net Asset Value (“NAV”) per share using the practical expedient in the FASB ASC Topic 820. Part III of the ASU provides a practical expedient to permit employee benefit plans to measure investments and investment-related accounts as of the month-end that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with a month-end, while requiring certain additional disclosures. The amendments in Parts I and II of this standard are effective retrospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. The amendments in Part III of this standard are effective prospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. We are currently evaluating the impact of this standard on our financial statements.

In June 2015, the FASB issued ASU 2015-10, “Technical Corrections and Improvements”. The amendments represent changes to clarify the codification, correct unintended application of guidance, or make minor improvements to the codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost. In addition, some of the amendments will make the codification easier to understand and easier to apply by eliminating inconsistencies, providing needed clarifications, and improving the presentation of guidance in the codification. The amendments that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon issuance. We are evaluating the impact of ASU 2015-10 on our financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” to simplify the presentation of debt issuance costs. The amendments in the update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction of the carrying amount of the debt. Recognition and measurement of debt issuance costs were not affected by this amendment. In August 2015, FASB issued ASU 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated With Line-of-Credit Arrangements – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting” which clarified that the SEC would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2015. This standard does not have an impact on our financial statements. As of September 30, 2015, we early adopted this standard and recorded debt issuance costs as a debt discount. There was no impact related to this adoption as we did not have any debt issuance costs previously.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact the adoption of ASU 2014-15 will have on our financial statements.

In May 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, “Revenue from Contracts with Customers”. The standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. We are currently evaluating the effect that the updated standard will have on our financial statements.

Results of operations for the three months ended September 30, 2015 and the three months ended September 30, 2014 reflected losses of approximately $2.3 million and $2.1 million for each period, respectively. These losses include in part non-cash charges related to stock-based compensation, depreciation and amortization, amortization of prepaid research and development – related party and deferred taxes, collectively in the amount of $228,000 for the three months ended September 30, 2015 and $233,000 for the three months ended September 30, 2014. The non-cash charges decreased in the three months ended 2015 primarily due to the decrease in stock-based compensation.

We recognized $466,000 and $6,000 for the three months ended 2015 and 2014 respectively, related to the sale of RedoxSYS and ProstaScint products.

The $21,000 license revenue we recognized for each of the three months ended 2015 and 2014, respectively, represent the amortization of the upfront payments received on our license agreements. The initial payment of $500,000 from the license agreement of Zertane with a Korean pharmaceutical company was deferred and is being recognized over ten years. The initial payment of $250,000 from the license agreement of Zertane with a Canadian-based supplier was deferred and is being recognized over seven years.

The cost of sales of $37,000 and $200 recognized for the three months ended September 30, 2015 and 2014, respectively, is related to the ProstaScint product and the RedoxSYS System.

Research and development costs consist of drug development and clinical trials, labor, as well as stock-based compensation. Costs of research and development decreased $84,000, or 8.5%, for the three months ended 2015 compared to the three months ended 2014. The decrease is primarily due to a decrease in stock-based compensation as a result of the cancellation of the Luoxis and Vyrix options.

Selling, general and administrative costs increased $578,000, or 51.1% for the three months ended 2015 compared to the three months ended 2014. The increase is primarily due to labor as a result of increased staffing due to our development and commercialization efforts for our products and product candidates offset by a decrease in professional fees and stock-based compensation.

During the three month period ended September 30, 2015, our operating activities used $2.2 million in cash which was slightly less than the net loss of $2.3 million primarily as a result of the non-cash depreciation, amortization and accretion and the increase in accrued compensation offset by inventory and accounts payable.

During the three month period ended September 30, 2014, our operating activities used $2.2 million in cash which was slightly more than the net loss of $2.1 million primarily as a result of a decrease in the payable to Ampio, accounts payable and increase in prepaid research and development offset by the decrease in prepaid expenses and the non-cash depreciation, amortization and accretion.

During the three month period ended September 30, 2015, cash of $4,000 was used to purchase fixed assets. There were no cash flows from investing activities in the three months ended September 30, 2014.

Net cash provided by financing activities in the three month period ended September 30, 2015 of $4.9 million was primarily related to the convertible promissory notes which reflects gross proceeds of $5.2 million offset by the cash portion of the debt issuance costs related to the Notes of $298,000.

During the three months ended September 30, 2015, the only proceeds in financing activities was a $600,000 contribution from Ampio.

As we are a fairly young company, so we have not yet generated significant revenue as our primary activities are focused on commercializing our primary product candidates, and raising capital. As of September 30, 2015, we had cash and cash equivalents totaling $10.1 million available to fund our operations and $1.1 million in accounts payable. Based upon these figures plus the Ampio commitment to fund our Company with another $5.0 million, we believe we have adequate capital to continue operations into the first half of 2017. We intend to seek additional capital within the next 12 months help acquire new products as well as general corporate purposes. In addition, we intend to evaluate the capital markets from time to time to determine when to raise additional capital in the form of equity, convertible debt or otherwise, depending on market conditions relative to our need for funds at such time, and we will seek to raise additional capital during the next 12 months, if at all, at such time as we conclude that such capital is available on terms that we consider to be in the best interests of us and our stockholders.

We have prepared a budget for calendar year 2015 which reflects cash requirements for fixed, on-going expenses such as payroll, legal and accounting, patents and overhead at an average cash burn rate of approximately $500,000 per month. We plan to

expend additional funds for regulatory approvals, clinical trials, outsourced research and development and commercialization consulting. Accordingly, it will be necessary to raise additional capital and/or enter into licensing or collaboration agreements. At this time, we expect to satisfy our future cash needs through Ampio’s contributions to us and private or public sales of our securities or debt financings. We cannot be certain that financing will be available to us on acceptable terms, or at all. Over the last three years, volatility in the financial markets has adversely affected the market capitalizations of many bioscience companies and generally made equity and debt financing more difficult to obtain. This volatility, coupled with other factors, may limit our access to additional financing.

If we cannot raise adequate additional capital in the future when we require it, we will be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. We also may be required to relinquish greater or all rights to product candidates at less favorable terms than we would otherwise choose. This may lead to impairment or other charges, which could materially affect our balance sheet and operating results.

We do not have off-balance sheet arrangements, financings, or other relationships with unconsolidated entities or other persons, also known as “variable interest entities”.

We are not currently exposed to material market risk arising from financial instruments, changes in interest rates or commodity prices, or fluctuations in foreign currencies. We have not identified a need to hedge against any of the foregoing risks and therefore currently engages in no hedging activities.

As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out by the our management, with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based on such evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the our disclosure controls and procedures are effective to ensure that information required to be disclosed in the reports we file or furnish under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and regulations, and are operating in an effective manner.

There were no changes in our internal controls over financial reporting that occurred during the first quarter of our fiscal year 2016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

We are currently not party to any material pending legal proceedings, whether routine or non-routine.

We operate in a rapidly changing environment that involves a number of risks that could materially affect our business, financial condition or future results, some of which are beyond our control. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in “Risk Factors” in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on September 28, 2015, which could materially affect our business, financial condition or future results. During the quarterly period covered by this Quarterly Report on Form 10-Q, there were no material changes to the risk factors described in our Form 10-K filed on September 28, 2015, except as set forth below.

We expect that significant additional capital will be needed in the future to continue our planned operations. To raise capital, we may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors in a prior transaction may be materially diluted by subsequent sales. Additionally, any such sales may result in material dilution to our existing stockholders, and new investors could gain rights, preferences and privileges senior to those of holders of our common stock. Further, any future sales of our common stock by us or resales of our common stock by our existing stockholders could cause the market price of our common stock to decline. Any future grants of options, warrants or other securities exercisable or convertible into our common stock (and the amount and pricing of such securities), or the exercise or conversion of such shares, and any sales of such shares in the market, could have an adverse effect on the market price of our common stock.

In addition, there is not now, nor has there been since our inception, any substantial trading activity in our common stock or a market for shares of our common stock, and an active trading market for our shares may never develop or be sustained. Given the illiquid nature of our common stock, the value of our common stock cannot necessarily be based on the price of our common stock as quoted on the OTCQB. Investors in future financings may be able to negotiate a price for our common stock or derivatives that is significantly less than the price quoted on the OTCQB. Such an event could have an adverse effect on the market price of our common stock

Further, the stock market in general, and the stocks of small-cap healthcare, biotechnology and pharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of, or other events reported by, these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance or public announcements, and could have a dramatic and material adverse impact on the market price of our common stock.

Pursuant to the requirements of the Securities and Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.

This Employment Agreement (the “Agreement”), is effective as of Sept 16, 2015 (the “Effective Date”), between Aytu Bioscience, Inc., a Delaware corporation headquartered at 373 Inverness Parkway, Suite 200, Englewood, CO 80112 USA, hereinafter referred to as the “Company”, and Jonathan McGrael (“Employee”).

WHEREAS, the Company desires to hire the Employee in order to retain the Employee’s experience, skills, abilities, background and knowledge, and is willing to employ the Employee’s services on the terms and conditions set forth in this Agreement; and

WHEREAS, Employee desires to be employed by the Company, and is willing to accept such employment on the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the foregoing, the mutual agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows

1. Employment. The Company hereby agrees to employ Employee and Employee hereby accepts such employment, beginning on the Effective Date and continuing until terminated by either party. Employee’s employment with the Company is at-will, and either party can terminate the employment relationship and/or this Agreement at any time, for any or no cause or reason, and with or without prior notice.

2. Position and Duties. Employee will serve as the Company’s Vice President of Sales, and will perform such services for the Company as are customarily associated with such position and as may otherwise be assigned to the Employee from time to time by the Company’s Chief Executive Officer. Employee will report to the Company’s Chief Executive Officer. Employee will devote his full business time to the affairs of the Company and to his duties hereunder, and will perform his duties diligently and to the best of his ability, in compliance with the Company’s policies and procedures and the laws and regulations that apply to the Company’s business. Employee may engage in any civic and not-for-profit activities so long as such activities do not materially interfere with the performance of his duties hereunder or present a conflict of interest with the Company. In addition, during his employment, Employee agrees not to acquire, assume or participate in, directly or indirectly, any position, investment or interest known by the Employee to be adverse or antagonistic to the Company, its business or prospects, its financial position, or otherwise or in any company, person or entity that is, directly or indirectly, in competition with the business of the Company or any of its affiliates.

3. Compensation. As compensation for the services to be rendered by Employee under this Agreement, the Company will provide the following compensation and benefits during Employee’s employment hereunder.

(a) Base Salary. The Company will pay Employee a base salary of $175,000 per annum, payable at least monthly on the Company’s regular pay cycle for professional employees (the “Base Salary”). The Base Salary may be reviewed from time to time by the Company, and may be increased in the sole discretion of the Company’s Board of Directors (the “Board”) or its designee. The Base Salary may also be decreased by the Board in connection with any Company-wide decrease in executive compensation.

(b) Annual Incentive Bonus. Employee will be eligible for an annual discretionary bonus (the “Bonus”) with a target amount of seventy-five thousand dollars ($75,000), based on the determination of the Board or its designee, in good faith, of the Employee’s and the Company’s achievement of certain individual and company performance objectives established by the Board or its designee (the “Performance Milestones”). The Performance Milestones will be based on certain factors including, but not limited to, the Employee’s performance and the Company’s financial performance. The Employee must be employed on the date the Bonus is paid to be eligible for the Bonus. The Bonus for any given year will be payable between two and one-half months following immediately following the conclusion of the year to which the Bonus relates.

(c) Equity Compensation. In connection with the execution of this Agreement, and subject to Board approval, the Company will grant to Employee an option to purchase 200,000 shares of the Company’s common stock (the “Option”). The Option will vest as to one third (1/3) of the total number of shares subject to the Option on the first, second, and third anniversary of Employee’s first date of employment with the Company, so long as Employee remains employed by the Company through each such vesting date. The Option exercise price will equal the fair market value on the date of grant as determined by the Board. The Option will be subject to the terms of the Company’s 2015 Stock Option and Incentive Plan (the “Plan”) and a related option grant agreement between Employee and the Company. The vesting of the Option will be accelerated upon the occurrence of a “Sale Event” as such term is defined in the Plan.

(d) Relocation Expenses. The Company will reimburse Employee for reasonable expenses incurred in moving himself and his family from his existing residence to his new residence in the Denver, Colorado or Raleigh, North Carolina area, up to a maximum of $20,000. Covered expenses will include carrier transportation by an approved carrier for normal household goods and personal effects, exclusive of automobiles, boats, recreational vehicles, explosives, firearms, outdoor structures, items of exceptional value, or any item in which the moving costs exceed its value, and customary packing and unpacking charges. Employee will have eighteen (18) months from the date his employment begins in which to use this benefit. Within thirty (30) days after incurring any covered expense, Employee will provide such documentation as may be reasonably requested by the Company to substantiate expenses to be reimbursed pursuant to this section. Any relocation expenses paid to Employee pursuant to this Section 3(d) will be subject to repayment by Employee if Employee resigns his employment without Good Reason (as defined below) or if the Company terminates Employee’s employment with Cause (as defined below) within twelve (12) months following the payment by the Company.

4. Employee Benefits. Employee will be entitled to participate in any group insurance, hospitalization, medical, health and accident, disability, fringe benefit and tax-qualified retirement plans or programs of the Company available to similarly-situated employees now existing or hereafter established to the extent that he is eligible under the general provisions thereof. Nothing in this Agreement will be deemed to alter the Company’s rights to modify or terminate any such plans or programs in its sole discretion. Employee will be entitled to earn paid vacation in accordance with Company policy.

5. Expenses. The Company will reimburse Employee for actual, reasonable out-of-pocket expenses incurred by him in the performance of his services for the Company upon the receipt of appropriate documentation of such expenses which will be submitted in such form, and with such supporting documentation, as called for or required by Company policy. Such reimbursements will be made in a timely manner and in accordance with the policies of the Company, but in no event later than December 31 of the year following the year in which Employee incurs such expense. The amount of expenses eligible for reimbursement during one year will not affect the expenses eligible for reimbursement in any other year, and the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

(a) In General. Employee’s employment hereunder will end automatically upon his death. Employee’s employment may also be by either party upon written notice to the other at any time, for any reason or for no reason.

(b) Effect on Other Positions. On termination of Employee’s employment, regardless of the reason for such termination, Employee will immediately, automatically, and with contemporaneous effect, resign any directorships, offices, or other positions that Employee may hold in the Company or any affiliate, unless otherwise agreed in writing by the parties.

(c) Notification of New Employer. In the event that Employee leaves the employ of the Company for any reason, Employee consents and agrees that the Company may notify Employee’s new employer regarding Employee’s obligations under this Agreement and the PIA (hereinafter defined).

(a) In General. When Employee’s employment with the Company is terminated for any reason, Employee, or his estate, as the case may be, will be entitled to receive the compensation and benefits earned through the effective date of termination (including accrued but unused vacation pay to the extent required by pursuant to Company policy or by law). Such amounts will be paid on the first regular pay date after the date of termination (or earlier, if required by applicable law). In addition, Employee (or his estate) will be entitled to receive reimbursement for any outstanding business expenses that Employee has timely submitted for reimbursement in accordance with the Company’s expense reimbursement policy or practice.

(b) Termination without Cause or for Good Reason. In the event that the Company terminates Employee’s employment hereunder without Cause, or the Employee terminates his employment with Good Reason, then conditioned upon Employee executing a Release (as defined below) following such termination, the Company will provide to Employee the following separation benefits (collectively, the “Separation Benefits”): (i) continued payment of Employee’s then-current Base Salary for a period of six (6) months; and (ii) accelerated vesting of the then-unvested portion of the Option in its entirety. The Separation Benefits are conditioned upon Employee executing a general release of claims in a form acceptable to the Company (the “Release”) within the time specified therein, which Release is not revoked within any time period allowed for revocation under applicable law. The salary continuation described in clause (i) above will be payable to Employee over time in accordance with the Company’s payroll practices and procedures beginning on the sixtieth (60th) day following the termination of Employee’s employment with the Company, and the accelerated vesting described in clause (ii) above will occur on the sixtieth (60th) day following the termination of Employee’s employment with the Company. Notwithstanding the foregoing, if Employee is entitled to receive the salary continuation described in clause (i) above but violates any provisions of the PIA after termination of employment, the Company will be entitled to immediately stop paying any further installments of such salary continuation, in addition to any other remedies that may be available to the Company in law or at equity. For avoidance of doubt, the termination of Employee’s employment as a result of his death or disability (meaning the inability of Employee, due to the condition of his physical, mental or emotional health, effectively to perform the essential functions of his job with or without reasonable accommodation for a continuous period of more than 90 days or for 90 days in any period of 180 consecutive days, as determined by the Company in its sole discretion) will not constitute a termination without Cause triggering the rights described in this Section 7(b).

(c) Cause Defined. “Cause” means (i) willful malfeasance or willful misconduct by Employee in connection with his employment; (ii) Employee’s gross negligence in performing any of his duties under this Agreement; (iii) Employee’s conviction of, or entry of a plea of guilty to, or entry of a plea of nolo contendere with respect to, a felony or misdemeanor involving moral turpitude; (iv) Employee’s material failure to comply with the Company’s workplace rules, policies, or procedures; (v) the Employee’s unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party as to which the Employee owes an obligation of nondisclosure as a result of the Employee’s relationship with the Company; (vi) Employee’s material breach of the PIA; (vii) Employee’s material breach of this Agreement; or (viii) Employee’s willful failure or refusal to perform his material duties under this Agreement or failure to follow any specific lawful instructions of the Chief Executive Officer or his designee. In the event that the Company concludes that Employee has engaged in acts constituting in Cause as defined in clause (iv), (vii), or (viii) above, prior to terminating his employment for Cause the Company will provide Employee with at least fifteen (15) days’ advance written notice of the specific circumstances constituting such Cause, and an opportunity to correct such circumstances, to the extent such circumstances are susceptible of being cured.

(d) Good Reason Defined. For purposes of this Agreement, “Good Reason” means the occurrence of any of the following events without Employee’s written consent: (i) a material reduction of Employee’s Base Salary (except where there is a general reduction applicable to the management team generally, provided, however, that in no case may the Base Salary be reduced below the amount stated in Section 3(a)); (ii) a material reduction in Employee’s overall responsibilities or authority, or scope of duties; or (iii) the Company’s material breach of this Agreement. In order for Employee to resign for Good Reason, Employee must provide written notice to the Company of the existence of the Good Reason condition within thirty (30) days of the initial existence of such Good Reason condition. Upon receipt of such notice, the Company will have fifteen (15) days during which it may attempt to remedy the Good Reason condition and not be required to provide for the benefits described in Section 7(b) above as a result of such proposed resignation if successfully remedied. If the Good Reason condition is not remedied within such fifteen (15) day period, Employee may resign based on the Good Reason condition specified in the notice effective no later than thirty (30) days following the expiration of the fifteen (15) day cure period.

8. Proprietary Information and Inventions Agreement. As a condition of Employee’s employment with the Company, Employee agrees to sign the Company’s standard form of Proprietary Information and Inventions Agreement (“PIA”).

9. Successors and Assigns. This Agreement will be binding upon and inure to the benefit of the parties and their respective successors, permitted assigns and, in the case of Employee, heirs, executors, and/or personal representatives. The Company may freely assign or transfer this Agreement to an affiliated company or to a successor following a merger, consolidation, sale of assets, or other business transaction. This Agreement is a personal contract, and as such Employee may not assign, delegate or otherwise transfer any of Employee’s rights, interests or obligations in this Agreement without the prior written approval of the Company.

10. Entire Agreement. This Agreement (together with the equity award agreements referred to herein and the PIA) represents the entire agreement between the parties concerning Employee’s employment with the Company and supersedes all prior negotiations, discussions, understanding and agreements, whether written or oral, between Employee and the Company relating to the subject matter of this Agreement.

11. Amendment or Modification, Waiver. No provision of this Agreement may be amended or waived unless such amendment or waiver is agreed to in writing signed by Employee and by a duly authorized officer of the Company. No waiver by any party to this Agreement or any breach by another party of any condition or provision of this Agreement to be performed by such other party will be deemed a waiver of a similar or dissimilar condition or provision at the same time, any prior time or any subsequent time.

12. Notices. Any notice to be given under this Agreement will be in writing and delivered personally or sent by overnight courier or registered or certified mail, postage prepaid, return receipt requested, addressed to the party concerned at the address indicated below, or to such other address of which such party subsequently may give notice in writing:

Any notice delivered personally or by overnight courier will be deemed given on the date delivered and any notice sent by registered or certified mail, postage prepaid, return receipt requested, will be deemed given on the date two (2) days after it is deposited in the custody of the U.S. Postal Service.

13. Severability. If any provision of this Agreement or the application of any such provision to any party or circumstances will be determined by any court of competent jurisdiction or arbitrator acting pursuant to Section 19 below to be invalid and unenforceable to any extent, the remainder of this Agreement or the application of such provision to such person or circumstances other than those to which it is so determined to be invalid and unenforceable will not be affected, and each provision of this Agreement will be validated and will be enforced to the fullest extent permitted by law. If for any reason any provision of this Agreement containing restrictions is held to cover an area or to be for a length of time that is unreasonable or in any other way is construed to be too broad or to any extent invalid, such provision will not be determined to be entirely null, void and of no effect; instead, it is the intention and desire of both the Company and Employee that, to the extent that the provision is or would be valid or enforceable under applicable law, any court of competent jurisdiction or arbitrator acting pursuant to Section 19 below will construe and interpret or reform this Agreement to provide for a restriction having the maximum enforceable area, time period and such other constraints or conditions (although not greater than those contained currently contained in this Agreement) as will be valid and enforceable under the applicable law.

14. Survivorship. The respective rights and obligations of the parties hereunder will survive any termination of this Agreement to the extent necessary to the intended preservation of such rights and obligations.

15. Headings. All descriptive headings of sections and paragraphs in this Agreement are intended solely for convenience of reference, and no provision of this Agreement is to be construed by reference to the heading of any section or paragraph.

16. Withholding Taxes. All salary, benefits, reimbursements and any other payments to Employee under this Agreement will be subject to all applicable payroll and withholding taxes and deductions required by any law, rule or regulation of and federal, state or local authority.

17. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together constitute one and same instrument. The parties agree that facsimile signatures will have the same force and effect as original signatures.

18. Applicable Law. The validity, interpretation and enforcement of this Agreement and any amendments or modifications hereto will be governed by the laws of the State of Colorado, as applied to a contract executed within and to be performed in such State.

19. Arbitration. To facilitate the rapid and economical resolution of any disputes that may arise during Employee’s employment hereunder, Employee and the Company agree that any controversy or claim arising out of or relating to this Agreement, or any amendment or renewal hereof, or its negotiation, execution, construction, enforceability or performance, or any alleged breach hereof, or any claim between the parties which relates to the employment of Employee by the Company (including but not limited to claims based in tort or those which are statutory in nature and claims relating to discrimination of any kind) will be finally determined by binding arbitration conducted in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association (or its successor entity) then in effect (the “Rules”), and subject to the provisions set forth below.

(a) Any such arbitration will be conducted before a single arbitrator chosen in accordance with the Rules. Each party hereto will bear the costs of the arbitrator equally, unless otherwise ordered by the arbitrator. The arbitrator will have the authority to order discovery as permitted by the Rules. The arbitrator, and not a court, will be authorized to determine whether the provisions of this Section apply to a dispute, controversy, or claim sought to be resolved in accordance with these arbitration procedures.

(b) The arbitration proceedings will be held in the Denver, Colorado metropolitan area, unless otherwise mutually agreed by the parties. Any such arbitration will be treated as confidential by all parties thereto, except as otherwise provided by law or as otherwise necessary to enforce any judgment or order issued by the arbitrator.

(c) Judgment on the award rendered by the arbitrator may be entered and enforced by any court having jurisdiction thereof. Notwithstanding anything herein to the contrary, if either party seeks preliminary injunctive relief to protect its rights, then such party will have the power, without waiving this arbitration agreement, to invoke the jurisdiction of any court having jurisdiction for the exclusive purpose of obtaining such preliminary injunctive relief, and for such purposes each party hereby consents to the jurisdiction of, and laying of venue in, the state and federal courts sitting in Denver, Colorado. Each party hereby waives and agrees not to assert, to the fullest extent permitted by applicable law, any claim that (i) such party is not subject to the jurisdiction or venue of such courts, (ii) such party is immune from any legal process issued by such courts, (iii) any litigation or other proceeding commenced in such courts is brought in an inconvenient forum, and (iv) that any action by a party to seek preliminary injunctive relief in such court is a waiver of such party’s right to enforce this arbitration agreement.

(a) The parties intend that this Agreement will be administered in accordance with Section 409A of the of the Internal Revenue Code of 1986, as amended (the “Code”). To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision will be read in such a manner so that all payments hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

(b) To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon Employee’s termination of employment, then such payments or benefits will be payable only upon Employee’s “separation from service.” The determination of whether and when a separation from service has occurred will be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

(c) Anything in this Agreement to the contrary notwithstanding, if at the time of Employee’s separation from service within the meaning of Section 409A of the Code, the Company determines that Employee is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that Employee becomes entitled to under this Agreement on account of Employee’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment will not be payable and such benefit will not be provided until the date that is the earlier of (A) six months and one day after Employee’s separation from service, or (B) Employee’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment will include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments will be payable in accordance with their original schedule.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first written above.

In connection with the filing of the quarterly report on Form 10-Q for the quarter ended September 30, 2015 (the “Report”) by Aytu BioScience, Inc. (the “Company”), each of the undersigned hereby certifies that:

Aim	Hypothesis	Methods and Procedures	Expected Outcome
2	ORP values can be detected in fresh and frozen semen samples	1. Compare the effect of rapid freezing on the ORP of the seminal ejaculate and seminal plasma 2. The effect of exogenous ROS addition to the ORP and capacitance of both ejaculate and seminal plasma after rapid freezing 3. Establish the effect of different subzero storage temperatures and storage time on ORP measurement in frozen seminal ejaculate and seminal plasma samples 4. Comparing the effect of storage time after rapid freezing on the ORP of both the seminal ejaculate and seminal plasma	It shall be confirmed that ORP can be measured in both fresh and frozen semen samples and that n differences will exist

3	Establish ORP values in ejaculates of healthy men.	1. Establish ORP values in seminal ejaculates of healthy men with normal semen parameters i.e. normal concentration, motility and morphology according to WHO, 2010 2. Establish the effect of varying sperm concentration 0, 10, 20, 40 and 100 X 10⁶/ mL on ORP levels (concentration response).	ORP values in ejaculates of healthy men will be established

4	Establish ORP values in ejaculates of with different clinical characteristics.	1. Establish the ORP values in seminal ejaculates in infertile men in the absence or presence of leukocytes (Endtz negative and Endtz positive) samples. 2. Establishing ORP in healthy normozoospermic donors and infertile men with an abnormal spermiogram 3. Examine effect of abstinence on ORP in semen samples from normozoospermic donors 4. ORP levels in infertile men with varicocele	Specific and different ORP values will be established in the ejaculates from men with different pathologies

5	The ORP values correlate with ROS-TAC scores in ejaculates of healthy men.	1. Comparative study between ORP and. ROS–TAC scores as measured by chemiluminescence and total antioxidant capacity	A positive correlation will be found between ORP values and ROS-TAC scores


Study Summary	Phase	N	Demographic	Outcome/Findings
Effect of Storage on Oxidative Biomarkers on Packed Red Blood Cells	Clinical Proof of Concept	10 patient specimens	Critically ill patients with a risk of developing transfusion-related acute lung injury	Oxidation-reduction potential significantly increased (p < 0.05) in the day 42 sample versus the day 1 sample. The oxidation of human serum albumin increased by 63.6% during the storage time.

Plasma Oxidation-Reduction Potential and Protein Oxidation in Traumatic Brain Injury	Clinical Proof of Concept	Non-head injury trauma patients = 26 Moderate ITBI patients = 18 Healthy patients = 22	Isolated traumatic brain injury	Admission plasma ORP was significantly elevated in all traumatized patients compared to controls. Maximum ORP was detected on day 6 for severe ITBI and non-head injury traumatized patients. Maximum ORP values were significantly higher p<0.05) in the severe ITBI group compared to the non-head injury group

Oxidation-reduction potential in trauma patients	Clinical Proof of Concept	Trauma patients = 39 Healthy patients = 10	Critically injured patients	The presence of an oxidative environment in the plasma of the critically injured as measured by ORP. ORP can differentiate the degree of oxidative stress based on the severity of the trauma and degree of inflammation
