Overview

We are a biopharmaceutical company with product candidates in pre-clinical and clinical development. Neurotrope BioScience began operations in October 2012. We are principally focused on developing a product platform based upon a drug candidate called bryostatin for the treatment of Alzheimer’s disease (“AD”), which is in the clinical testing stage. We are also developing bryostatin for other neurodegenerative or cognitive diseases and dysfunctions, such as Fragile X and Niemann-Pick Type C, which are in pre-clinical testing. Neurotrope has been a party to a technology license and services agreement with the original Blanchette Rockefeller Neurosciences Institute (“BRNI”) (which has been known as Cognitive Research Enterprises, Inc. (“CRE”) since October 2016), and its affiliate NRV II, LLC, which we collectively refer to herein as “CRE,” pursuant to which we now have an exclusive non-transferable license to certain patents and technologies required to develop our proposed products. Neurotrope BioScience was formed for the primary purpose of commercializing the technologies initially developed by BRNI for therapeutic applications for AD or other cognitive dysfunctions. These technologies have been under development by BRNI since 1999 and, until March 2013, had been financed through funding from a variety of non-investor sources (which include not-for-profit foundations, the National Institutes of Health, which is part of the U.S. Department of Health and Human Services, and individual philanthropists). From March 2013 forward, development of the licensed technology has been funded principally through Neurotrope BioScience in collaboration with CRE.

Results of Phase 2 Clinical Trial

 On May 1, 2017, we reported certain relevant top-line results from our Phase 2 exploratory clinical trial based on a preliminary analysis of a limited portion of the complete data set generated. Data from the Phase 2 exploratory trial evaluating Bryostatin-1 as a treatment of cognitive deficits in moderate to severe Alzheimer’s disease were recently published online in the Journal of Alzheimer's Disease.  A total of 147 patients were enrolled into the study; 135 patients in the mITT population and 113 in the Completer population. This study was the first repeat dose study of bryostatin-1 in patients with late stage AD (defined as a Mini Mental State Exam 2 (“MMSE-2”) of 4-15), in which two dose levels of bryostatin-1 were compared with placebo to assess safety and preliminary efficacy (p < 0.1, one-tailed) after 12 weeks of treatment. The pre-specified primary endpoint, the Severe Impairment Battery (the “SIB”) (used to evaluate cognition in severe dementia), compared each dose of bryostatin-1 with placebo at Week 13 in two sets of patients: (1) the modified intent-to-treat (the “mITT”) population, consisting of all patients who received study drug and had at least one efficacy/safety evaluation, and (2) the Completer population, consisting of those patients within the mITT population who completed the 13-week dosing protocol and cognitive assessments.

These announced top-line results indicated that the 20 µg dose, administered after two weekly 20 µg doses during the first two weeks and every other week thereafter, met the pre-specified primary endpoint in the Completer population, but not in the mITT population. Among the patients who completed the protocol (n = 113), the patients on the 20 µg dose at 13 weeks showed a mean increase on the SIB of 1.5 vs. a decrease in the placebo group of -1.1 (net improvement of 2.6, p < 0.07), whereas, in the mITT population, the 20 µg group had a mean increase on the SIB of 1.2 vs. a decrease in the placebo group of -0.8 (net improvement of 2.0, p < 0.134). At the pre-specified 5 week secondary endpoint, the Completer patients in the 20 µg group showed a net improvement of 4.0 SIB (p < 016), and the mITT population showed a net improvement of 3.0 (p< ,056).Unlike the 20 µg dose, there was no therapeutic signal observed with the 40 µg dose.

The Alzheimer Disease Cooperative Study Activities of Daily Living Inventory Severe Impairment version (ADCS-ADL-SIV) was another pre-specified secondary endpoint. The p values for the comparisons between 20 µg and placebo for the ADCS-ADL endpoint at 13 weeks were 0.082 for the Completers and 0.104, for the mITT population.

S-3

Together, these initial results after preliminary analysis of this exploratory trial, indicated that bryostatin-1, at the 20 µg dose, caused sustained improvement in important functions that are impaired in patients with moderate to severe Alzheimer’s disease i.e., cognition and the ability to care for oneself. Since most of the patients in this study were already taking donepezil and/or memantine, the efficacy of bryostatin-1 was evaluated in the Top Line results over and above the standard of care therapeutics.

 The safety profile of bryostatin-1 20 µg was minimally different from the placebo group except for a higher incidence of diarrhea and infusion reactions (11% versus 2% for diarrhea and 17% versus 6% for infusion reactions). Fewer adverse events were reported in patients in the 20 µg group, compared to the 40 µg group. Patients dosed with 20 µg had a dropout rate less than or identical to placebo, while patients dosed at 40 µg experienced poorer safety and tolerability, and had a higher dropout rate. Treatment emergent adverse events (“TEAEs”) were mostly mild or moderate in severity. TEAEs, including serious adverse events, were more common in the 40 µg group, as compared to the 20 µg and placebo groups. The mean age of patients in the study was 72 years and similar across all three treatment groups.

 Following presentation of the top line results in July 2017 at the Alzheimer’s Association International Conference in London, a much more extensive analysis of a more complete set of the Phase 2 trial data was conducted.

 On January 5, 2018, we announced that a post-hoc analysis of a comprehensive data set from our recent Phase 2 trial in patients with advanced Alzheimer’s disease (“AD”) found evidence of sustained improvement in cognition in patients receiving the 20 μg bryostatin regimen. In addition, patients who did not receive memantine, an approved AD treatment, as background therapy showed greater SIB improvement. These findings suggested that this investigational drug could potentially treat Alzheimer’s disease itself and help reduce and/or reverse the progression of AD, rather than only alleviate its symptoms.

 The comprehensive follow-on analysis found that patients in the 20 μg treatment arm showed a sustained improvement in cognition over baseline compared to the placebo group at week 15 (30 days after last dose at week 11). These data were observed in the study population as a whole.

 The follow-on analysis of the data evaluated SIB scores of patients at 15 weeks, 30 days after all dosing had been completed – a pre-specified exploratory endpoint. For the 20 μg group, patients in the mITT population (n=34) showed an overall improvement compared to controls (n=33) of 3.59 (p=0.0503) and in the Completers population (n=34) showed an overall improvement compared to controls (n=33) of 4.09 (p=0.0293). In summary, patients on the 20 μg dose showed a persistent SIB improvement 30 days after all dosing had been completed. These p-values and those below are one-tailed.

Additional analyses compared 20 µg dose patients who were on baseline therapy of Aricept vs. patients off Aricept. No significant differences were observed. Another analysis compared the 20 µg dose patients who were on or off baseline therapy of memantine. Post-hoc analysis comparing SIB scores in non-memantine versus memantine patients found the following:

· At week 15, non-memantine patients in the mITT Group treated with 20 μg (n=14) showed an SIB improvement of 5.88, while the placebo patients (n=11) showed a decline in their SIB scores of -0.05 for an overall treatment Δ of 5.93 from baseline (p=0.0576).

· At week 15, non-memantine patients in the Completers Group treated with 20 μg (n=14) showed an SIB improvement of 6.24, while the placebo patients (n=11) showed a decline in their SIB scores of -0.12 for an overall treatment Δ of 6.36 from baseline (p=0.0488).

· Patients taking memantine as background therapy in the 20 μg (n=20) and control (n=22) groups showed no improvement in SIB scores.

Memantine, an NMDA receptor antagonist, is marketed under the brand names Namenda®, Namenda® XR, and Namzaric® (a combination of memantine and donepezil) for the treatment of dementia in patients with moderate-to-severe AD. It has been shown to delay cognitive decline and help reduce disease symptoms. 

S-4

 Ongoing Confirmatory Phase 2 Clinical Trial

 On May 4, 2018, we announced a confirmatory, 100 patient, double-blinded clinical trial for the safe, effective 20 μg dose protocol for advanced AD patients not taking memantine as background therapy to evaluate improvements in SIB scores with an increased number of patients. As such, we have again engaged WCT, in conjunction with consultants and investigators at leading academic institutions to collaborate on the design and conduct of the next trial, which began in April, 2018. During July 2018, the first patient was enrolled in this study.

 As of October 16, 2018, the Company has signed up 28 clinical sites and has screened 82 patients. Of the total screened patients, 31 have been randomized and continue to be dosed.

 To the extent resources permit, we intend to pursue development of selected technology platforms with indications related to the treatment of AD and other neurodegenerative disorders based on our current licensed technology and / or technologies available from third party licensors or collaborators.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks described below and discussed under the section captioned “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2017, which is incorporated by reference in this prospectus supplement, and all other information contained in this prospectus supplement and the accompanying prospectus and incorporated by reference in this prospectus supplement and the accompanying prospectus, and in any free writing prospectus that we have authorized for use in connection with this offering, before purchasing shares of our common stock. These risks and uncertainties are not the only ones facing us. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of such risks or the risks described below or in our SEC filings occur, our business, financial condition or results of operations could be materially and adversely affected. In that case, the trading price of our common stock could decline, and you may lose some or all of your investment.

Risks Related to This Offering

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

Because we have not designated the amount of net proceeds from this offering to be used for any particular purpose, our management will have broad discretion as to the application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of the offering. Our management may use the net proceeds for corporate purposes that may not improve our financial condition or market value.

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.

Since the price per share of our common stock being offered is substantially higher than the net tangible book deficit per share of our common stock, you will suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering. As of September 30, 2018, our net tangible book value was approximately $9.3 million, or $1.174 per share. Based on the combined offering price of $4.495 per share of common stock and accompanying warrant offered hereby, and our net tangible book value as of September 30, 2018, if you purchase securities in this offering, you will suffer immediate and substantial dilution of $2.193 per share with respect to the net tangible book value of the common stock.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices, including offers with respect to our outstanding warrants, that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

In addition, the sale of shares in this offering and any future sales of a substantial number of shares of our common stock in the public market, or the perception that such sales may occur, could adversely affect the price of our common stock. We cannot predict the effect, if any, that market sales of those shares of common stock, or the perception that those shares may be sold, will have on the market price of our common stock.

S-7

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the securities offered under this prospectus supplement, after deducting placement agent fees and commissions, advisory financial consulting fees and other estimated offering expenses payable by us, will be approximately $20,455,988 million if we sell the maximum amount of common stock and warrants offered hereby. However, this is a best efforts offering with no minimum, and we may not sell all or any of the securities; as a result, we may receive significantly less in net proceeds, and the net proceeds received may not be sufficient to continue to operate our business. If a warrant holder elects to exercise the warrants issued in this offering, we may also receive proceeds from the exercise of the warrants. We cannot predict when or if the warrants will be exercised. It is possible that the warrants may expire and may never be exercised.

We intend to use the net proceeds from this offering for general corporate purposes. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses of the proceeds, if any, from this offering. Accordingly, we will retain broad discretion over the use of any such proceeds. Pending the use of the net proceeds, from this offering as described above, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

Investors are cautioned that the proceeds from this offering are expected to be sufficient to enable us to continue operations for only a short period of time. We expect that we will have to raise additional capital through the sale of additional equity or debt securities, including debt securities that may be convertible into equity securities. It may be difficult for us to raise additional funds when needed and on favorable terms, or at all.

S-8

DILUTION

If you invest in the securities offered by this prospectus supplement and the accompanying prospectus, you will experience immediate dilution to the extent of the difference between the price per share and warrant you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of September 30, 2018 was approximately $9.3 million, or approximately $1.174 per share of common stock. Net tangible book value per share as of September 30, 2018 equals the sum of our total tangible assets minus total liabilities, divided by the number of shares of our common stock outstanding as of September 30, 2018.

Dilution in net tangible book value per share represents the difference between the amount per share paid by the investor in this offering and the net tangible book value per share of our common stock immediately after this offering. After giving effect to the sale of 5,012,677 shares of our common stock in this offering at the offering price of $4.495 per share, and after deducting the placement agent fees, advisory financial consulting fees and the estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2018 would have been approximately $30.0 million, or approximately $2.302 per share of common stock. This represents an immediate increase in the net tangible book value of approximately $1.128 per share to our existing stockholders and an immediate dilution in the net tangible book value of approximately $2.193 per share to the investor participating in this offering. The following table illustrates this calculation on a per share basis.

Public offering price per share			$	4.495
Net tangible book value per share as of September 30, 2018	$	1.174
Increase in net tangible book value per share attributable to this offering	$	1.128
As adjusted net tangible book value per share as of September 30, 2018, after giving effect to this offering			$	2.302
Dilution per share to the investor purchasing shares in this offering			$	2.193

The number of shares of our common stock shown above to be outstanding immediately after this offering is based on 7,909,693 shares outstanding as of December 17, 2018, and excludes, as of such date:

· 1,520,246 shares of common stock issuable upon the exercise of outstanding stock options with a weighted average exercise price of $18.07 per share as of December 17, 2018;

· 565,077 shares of common stock reserved for issuance under the Neurotrope, Inc. 2017 Equity Incentive Plan, as amended, as of December 17, 2018; and

· 5,101,440 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $15.04 per share as of December 17, 2018.

To the extent that any of our outstanding options or warrants are exercised, new options are issued under our equity incentive plan or we otherwise issue additional shares of common stock in the future, there may be further dilution to the investor participating in this offering.

The warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise. If a registration statement registering the issuance of the shares of common stock underlying the warrants under the Securities Act is not then effective or available, and if a resale registration statement registering the resale of the shares of common stock underlying the warrants under the Securities Act is also not then effective or available, the holder may exercise the warrant through a cashless exercise, in whole or in part, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the warrant. No fractional shares of common stock will be issued in connection with the exercise of a warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.

Exercise Limitation. A holder will not have the right to exercise any portion of a warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or on election of the holder, 9.99%) of the number of shares of our stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99%, provided that any increase in such percentage shall not be effective until 61 days after such notice to us. 

Exercise Price. The initial exercise price per share of common stock purchasable upon exercise of the warrants is $4.37. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock.

Transferability. Subject to applicable laws, the warrants may be offered for sale, sold, transferred or assigned without our consent. There is currently no trading market for the warrants and a trading market is not expected to develop. 

Exchange Listing. We do not intend to list the warrants on any securities exchange or nationally recognized trading system.

Fundamental Transactions. In the event of a fundamental transaction, as described in the warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the holders of the warrants will be entitled to receive upon exercise of the warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the warrants immediately prior to such fundamental transaction.

Rights as a Stockholder. Except as otherwise provided in the warrants or by virtue of such holder’s ownership of shares of our common stock, the holder of a warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the warrant.

PLAN OF DISTRIBUTION

Pursuant to a placement agent agreement, we have engaged GP Nurmenkari Inc. (the “Placement Agent”) as placement agent, to solicit offers to purchase the common stock and warrants offered by this prospectus supplement. The placement agent is not purchasing any common stock or warrants for its own account in this offering, and is not required to arrange the purchase or sale of any additional specific number or dollar amount of the securities. We have additionally engaged Maxim Group LLC (“Maxim”) and Katalyst Securities LLC (“Katalyst”) as financing advisory consultants in connection with the registered direct offering.

The placement agent has agreed to use its reasonable best efforts to arrange for the sale of all of the securities in this offering. There is no requirement that any minimum number of shares of common stock or warrants or dollar amount of common stock or warrants be sold in this offering and there can be no assurance that we will sell all or any of the common stock and warrants being offered. We will enter into securities purchase agreements directly with accredited investors who purchase securities in this offering.

We currently anticipate that the closing of this offering will occur on or about December 19, 2018, subject to customary closing conditions. On the closing date, the following will occur:

· we will receive funds in the amount of the aggregate purchase price;

· the placement agent will receive the placement agent fees in accordance with the terms of the placement agent agreement; and

· we will deliver the shares of common stock and warrants to the investors.

We have agreed to pay the placement agent (i) a cash fee equal to 8% of the aggregate gross proceeds from investors first contacted by the placement agent in connection with the registered direct offering and (ii) warrants to purchase the number of shares of common stock equal to 8% of the aggregate number of shares sold to investors first contacted by the placement agent in connection with the registered direct offering. We have also agreed to reimburse the placement agent an additional $25,000 for its legal expenses.

The placement agent warrants will have substantially the same terms as the warrants issued to the investors in this offering, except that the placement agent warrants will have an exercise price equal to $4.495, or 100% of the offering price per share and warrant in this offering and such placement agent warrants will have a term of five years from the effective date of this offering. Pursuant to FINRA Rule 5110(g), the placement agent warrants and any shares issued upon exercise of the placement agent warrants shall not be sold, transferred, assigned, pledged, or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following the date of effectiveness or commencement of sales of this offering, except the transfer of any security: (i) by operation of law or by reason of our reorganization; (ii) to any FINRA member firm participating in this offering and the officers or partners thereof, if all securities so transferred remain subject to the lock-up restriction set forth above for the remainder of the time period; (iii) if the aggregate amount of our securities held by the placement agent or related persons do not exceed 1% of the securities being offered; (iv) that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided that no participating member manages or otherwise directs investments by the fund and the participating members in the aggregate do not own more than 10% of the equity in the fund; or (v) the exercise or conversion of any security, if all securities remain subject to the lock-up restriction set forth above for the remainder of the time period.

In addition, we engaged each of Maxim Group LLC (“Maxim”) and Katalyst Securities LLC (“Katalyst”) as advisory financial consultants in connection with the registered direct offering. We agreed to pay to Maxim and Katalyst an advisory consulting fee of $225,000 and $1.15 million, respectively, plus reimbursement of up to $25,000 of each of their legal expenses. In addition, each of Maxim and Katalyst shall receive warrants to purchase 50,000 shares of common stock and 256,000 shares of common stock, respectively. Such warrants issued to the advisory financial consultants shall have the same terms and be in the same form as the placement agent warrants described above.

S-11

The following table shows the placement agent fees and advisory consulting fees per share and accompanying warrants and total fees we will pay in connection with the sale of the common stock and warrants, assuming the purchase of all of the common stock and warrants we are offering.

Placement agent and advisory consulting fees
Per share and accompanying warrants	$	0.359
Total	$	1,800,995

We estimate the total expenses of this offering which will be payable by us, excluding the placement agent fees and advisory consulting fees and expense reimbursements to the placement agent and consultants, will be approximately $200,000. After deducting the fees due to the placement agent, the advisory consultants and our estimated offering expenses, we expect the net proceeds from this offering to be approximately $20,455,988 million.

We have agreed to indemnify the placement agent, the consultants and certain other persons against certain liabilities relating to or arising out of the placement agent’s or either consultant’s activities under their respective agreements. We have also agreed to contribute to payments that the placement agent may be required to make in respect of such liabilities.

Overview

We are a biopharmaceutical company with product candidates in pre-clinical and clinical development. Neurotrope BioScience began operations in October 2012. We are principally focused on developing a product platform based upon a drug candidate called bryostatin for the treatment of Alzheimer’s disease (“AD”), which is in the clinical testing stage. We are also developing bryostatin for other neurodegenerative or cognitive diseases and dysfunctions, such as Fragile X and Niemann-Pick Type C, which are in pre-clinical testing.  Neurotrope has been a party to a technology license and services agreement with the original Blanchette Rockefeller Neurosciences Institute (“BRNI”) (which has been known as Cognitive Research Enterprises, Inc. (“CRE”) since October 2016), and its affiliate NRV II, LLC, which we collectively refer to herein as “CRE,” pursuant to which we now have an exclusive non-transferable license to certain patents and technologies required to develop our proposed products.  Neurotrope BioScience was formed for the primary purpose of commercializing the technologies initially developed originally by BRNI for therapeutic applications for AD or other cognitive dysfunctions. These technologies have been under development by BRNI since 1999 and, until March 2013, had been financed through funding from a variety of non-investor sources (which include not-for-profit foundations, the National Institutes of Health, which is part of the U.S. Department of Health and Human Services, and individual philanthropists). From March 2013 forward, development of the licensed technology has been funded principally through Neurotrope BioScience in collaboration with CRE.

According to the Alzheimer’s Association, an estimated 36 million people worldwide had AD in 2015. The prevalence of AD is independent of race, ethnicity, geography, life style and, to a large extent, genetics. The most common cause of developing AD is old age. In developing countries, where the median age of death is less than 65 years old, AD is rarely recognized or diagnosed. In the U.S., 5.3 million people were estimated to have AD in 2015, and 96% of these people were older than 65 years of age.

Researchers have explored and continue to explore a wide range of drug mechanisms in hopes of developing drugs to combat AD. We believe that our approach, which involves the activation of an enzyme called protein kinase C epsilon (“PKCε”), represents a novel mechanism in potential AD drug therapies. Bryostatin-1, our lead PKC epsilon activator, has in animal studies demonstrated potential for multi-modal efficacies: prevention of neuronal death, generation of new synaptic networks, anti-amyloid oligomers and plaques, anti-tau and neurofibrillary tangles, and cognitive enhancement.

CRE conducted an expanded access program, formerly known as compassionate use, of bryostatin-1 in patients with advanced AD. Five patients were treated, four of which were treated under an Investigational New Drug Application (“IND”), cleared by the U.S. Food and Drug Administration (the “FDA”). The IND was initially held by CRE and was transferred to Neurotrope on February 4, 2015. One of these patients, who had familial AD, has died, but the death was not drug-related. Treatment of another one of these patients concluded after almost one year on the protocol. We have provided limited funding, study drug, and personnel support under the terms of our agreement with CRE for this modest expansion of our clinical effort in AD during the 2016 timeframe. 

1

In October 2015, we announced the initiation of a Phase 2 clinical trial to evaluate bryostatin for the treatment of patients with moderately severe to severe AD. We have completed enrollment, randomization and dosing of 148 patients in this double-blind, placebo-controlled study at 29 sites in the United States. The primary objective of the clinical trial is to assess the safety along with preliminary evaluation of efficacy of two doses of bryostatin in the patient population. We believe bryostatin may restore synaptic structures and functions damaged by AD, leading to improvements in cognition and memory. Beyond AD, we believe that several other neurologic diseases, such as Fragile X Syndrome and Niemann Pick Type C Disease (both of which we are pursuing), ischemic stroke, traumatic brain injury, depression and aging in the brain, may be amenable to treatment with bryostatin. In August 2016, we announced that we submitted to the FDA an amended protocol for our Phase 2 clinical trial of lead candidate bryostatin-1 for the treatment of advanced AD. As planned in the original protocol, the primary efficacy outcome will occur at Week 13, and does not change with the amendment. The primary efficacy endpoint is based on the Severe Impairment Battery scale, a well-validated assessment used extensively in severe AD drug trials. Secondary efficacy endpoints include Activities of Daily Living, Neuropsychiatric Inventory and Mini-Mental State Exam. As a result of the amendment, we expect to report top line data in the second quarter of 2017.

To the extent resources permit, we intend to pursue development of selected technology platforms with applications related to the treatment of AD and other neurodegenerative disorders based on our current licensed technology or technology available from third party licensors or collaborators.

Organizational History

We were incorporated as BlueFlash Communications, Inc. in Florida on January 11, 2011. Prior to the Reverse Merger (as defined below) and Split-Off (as defined below), our business was to provide software solutions to deliver geo-location targeted coupon advertising to mobile internet devices.

On August 9, 2013, we reincorporated in the State of Nevada by merging into a newly-formed special-purpose subsidiary, Neurotrope, Inc., which was incorporated on June 13, 2013, and was the surviving corporation in such reincorporation merger, or the Reincorporation Merger. As a result of the Reincorporation Merger, (i) we changed our name to Neurotrope, Inc. and (ii) we changed our jurisdiction of incorporation from Florida to Nevada.

On August 23, 2013, our wholly-owned subsidiary, Neurotrope Acquisition, Inc., or Acquisition Sub, a corporation formed in the State of Nevada on August 15, 2013 merged with and into Neurotrope BioScience, a corporation incorporated in the State of Delaware on October 31, 2012. Neurotrope BioScience was the surviving corporation in the merger, or the Reverse Merger, and became our wholly-owned subsidiary. All of the outstanding shares of Neurotrope BioScience common stock, (“Neurotrope BioScience Common Stock”), were converted into shares of our common stock, par value $0.0001 per share, and all of the outstanding shares of Neurotrope BioScience Series A Stock were converted into shares of our Series A Stock, in each case on a one-for-one basis.

In connection with the Reverse Merger and pursuant to a split-off agreement (the “Split-Off”), we transferred our pre-Reverse Merger business to Marissa Watson, our pre-Reverse Merger majority stockholder, in exchange for the surrender and cancellation of certain shares of our common stock owned by her.

As a result of the Reverse Merger and Split-Off, we discontinued our pre-Reverse Merger business and acquired the business of Neurotrope BioScience. Following the Reverse Merger and Split-Off, we have undertaken the business operations of Neurotrope BioScience as a publicly-traded company under the name Neurotrope, Inc., through Neurotrope BioScience, which is now our wholly-owned subsidiary.

In accordance with “reverse merger” accounting treatment, our historical financial statements as of period ends, and for periods ended, prior to the Reverse Merger were replaced with the historical financial statements of Neurotrope BioScience prior to the Reverse Merger in all applicable filings with the Securities and Exchange Commission (the “SEC”).

On January 11, 2017, we effected a 1-for-32 reverse stock split of our shares of common stock. As a result of the reverse stock split, every thirty-two (32) shares of our pre-reverse split common stock was combined and reclassified into one share of common stock. All references to common shares have been retroactively adjusted to reflect the reverse stock split. In addition, our pre-reverse split 400,000,000 authorized shares of common stock was proportionately reduced to 12,500,000 authorized shares of common stock as a result of the reverse stock split.

On February 24, 2017, we increased our authorized common stock to 150,000,000 shares.

USE OF PROCEEDS

We cannot assure you that we will receive any proceeds in connection with securities which may be offered pursuant to this prospectus. Unless otherwise indicated in the applicable prospectus supplement, we intend to use any net proceeds from the sale of securities under this prospectus for our operations and for other general corporate purposes, including, but not limited to, our research and development programs and the development of new programs, general working capital and possible future acquisitions. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures. As a result, our management will have broad discretion to allocate the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus for any purpose. Pending application of the net proceeds as described above, we may initially invest the net proceeds in short-term, investment-grade, interest-bearing securities or apply them to the reduction of short-term indebtedness.

PLAN OF DISTRIBUTION

General Plan of Distribution

We may offer securities under this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities (1) through underwriters or dealers, (2) through agents or (3) directly to one or more purchasers, or through a combination of such methods. We may distribute the securities from time to time in one or more transactions at:

· a fixed price or prices, which may be changed from time to time;

· market prices prevailing at the time of sale;

· prices related to the prevailing market prices; or

· negotiated prices.

We may directly solicit offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in a prospectus supplement any underwriter or agent involved in the offer or sale of the securities.

If we utilize a dealer in the sale of the securities being offered by this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale, and we will provide the name of any underwriter in the prospectus supplement which the underwriter will use to make re-sales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of the securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

With respect to underwritten public offerings, negotiated transactions and block trades, we will provide in the applicable prospectus supplement information regarding any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, or the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof.

5

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

· the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and

· if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

Shares of our common stock sold pursuant to the registration statement of which this prospectus is a part will be authorized for quotation and trading on The NASDAQ Capital Market. The applicable prospectus supplement will contain information, where applicable, as to any other listing, if any, on The NASDAQ Capital Market or any securities market or other securities exchange of the securities covered by the prospectus supplement. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

In order to facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing the applicable security in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.

The underwriters, dealers and agents may engage in other transactions with us, or perform other services for us, in the ordinary course of their business.

DESCRIPTION OF CAPITAL STOCK

General

The following description of our capital stock and provisions of our articles of incorporation, as amended (the “Articles of Incorporation”) and amended and restated bylaws (the “Bylaws”) are summaries and are qualified by reference to the Articles of Incorporation and the Bylaws that are on file with the SEC.

6

We have authorized capital stock consisting of 150,000,000 shares of common stock, $0.0001 par value, and 50,000,000 shares of preferred stock, $0.0001 par value, 24,325,000 of which shares have been designated as Series A Stock and 333,333 of which shares have been designated as Series B Stock.

As of March 27, 2017, we had issued and outstanding:

· 7,837,882 shares of our common stock held by 370 stockholders of record;

· 0 shares of Series A Stock;

· 0 shares of Series B Stock;

· Series A, Series C, Series E and Series F warrants to purchase 4,755,749 shares of our common stock;

· Placement agent warrants to purchase 409,376 shares of our common stock; and

· Options to purchase 753,235 shares of our common stock, at a weighted average exercise price of $22.99 per share.

Common Stock

The holders of our common stock are entitled to receive dividends out of assets or funds legally available for the payment of dividends at such times and in such amounts as the Board from time to time may determine. Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. There is no cumulative voting of the election of directors then standing for election. Our common stock is not entitled to pre-emptive rights and is not subject to conversion or redemption. Upon liquidation, dissolution or winding up of the Company, the assets legally available for distribution to stockholders are distributable ratably among the holders of our common stock after payment of liabilities, accrued dividends and liquidation preferences, if any. Each outstanding share of our common stock is duly and validly issued, fully paid and non-assessable.

Preferred Stock

Shares of preferred stock may be issued from time to time in one or more series, each of which will have such distinctive designation or title as shall be determined by our Board prior to the issuance of any shares thereof. Preferred stock will have such voting powers, full or limited, or no voting powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution or resolutions providing for the issue of such class or series of preferred stock as may be adopted from time to time by the Board prior to the issuance of any shares thereof. The number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all the then outstanding shares of our capital stock entitled to vote generally in the election of the directors, voting together as a single class, without a separate vote of the holders of the preferred stock, or any series thereof, unless a vote of any such holders is required pursuant to any preferred stock designation.

While we do not currently have any plans for the issuance of additional preferred stock, the issuance of such preferred stock could adversely affect the rights of the holders of common stock and, therefore, reduce the value of the common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders of the common stock until the Board determines the specific rights of the holders of the preferred stock; however, these effects may include:

· Restricting dividends on the common stock;

· Diluting the voting power of the common stock;

· Impairing the liquidation rights of the common stock; or

· Delaying or preventing a change in control of the Company without further action by the stockholders.

7

Other than in connection with shares of preferred stock (as explained above), which preferred stock is not currently designated nor contemplated by us, we do not believe that any provision of our charter or By-Laws would delay, defer or prevent a change in control.

We currently do not have any shares of preferred stock outstanding.

Options

Options to purchase an aggregate of 683,235 shares of our common stock have been issued under the Neurotrope, Inc. 2013 Plan as of March 27, 2017. Also as of March 27, 2017, options to purchase an aggregate of 70,000 shares of our common stock have been issued under the Neurotrope, Inc. 2017 Equity Incentive Plan, which was approved by the Board on March 9, 2017.

Warrants

As of March 27, 2017, we have outstanding placement agent warrants that entitle their holders to purchase: 15,953 shares of our common stock, with a term of ten years (from either August 23, 2013 or October 4, 2013) at an exercise price of $0.32 per share; 1,577 shares of common stock, with a term of five years (from either August 23, 2013 or October 4, 2013, as applicable) and an exercise price of $0.32 per share, 8,959 shares of common stock, with a term of five years (from either November 13^th or 30^th, 2015, as applicable) at an exercise price of $0.32 per share, and 382,887 shares of common stock, with a term of five years (from either November 17 or 22, 2016) at an exercise price of $6.40 per share. The placement agent warrants contain customary provisions for adjustment in the event of stock splits, subdivision or combination, mergers, etc. The holders of the placement agent warrants have the right to exercise the warrant by means of a cashless basis.

On November 13, 2015, we entered into a Securities Purchase Agreement to sell up to 819,914 units in a private placement at a per unit purchase price equal to $19.20 (the “November 2015 Private Placement”). Each unit consisted of (i) one one-hundredth share of Series B Stock convertible into one share of our common stock (which conversion occurred on November 17, 2016, for all shares of Series B Stock then issued and outstanding), (ii) one warrant to acquire, at an exercise price of $25.60 per share with an expiration date five years from the date of issuance, one share of our common stock (the “Series A Warrant”), (iii) one warrant to acquire, at an exercise price of $25.60 per share with an expiration date of one year from the date of issuance, one share of our common stock (the “Series B Warrant”), (iv) one warrant to acquire, at an exercise price of $40.00 per share with an expiration date of five years from the issuance date, one share of our common stock (the “Series C Warrant”), (v) one warrant, which is contingent upon the exercise of the Series B Warrant, to acquire, at an exercise price of $32.00 per share with an expiration date that is five years from the date of the initial exercise of the Series B Warrant, one share of our common stock (the “Series D Warrant”), and (vi) one warrant, which is contingent upon the exercise of the Series C Warrant, to acquire, at an initial exercise price of $48.00 per share with an expiration date that is five years from the date of the initial exercise of the Series C Warrant, one share of our common stock (the “Series E Warrant”, and together with the Series A Warrant, the Series B Warrant, the Series C Warrant and the Series D Warrant, the “Investor Warrants”). The exercise prices of the Investor Warrants were initially subject to full protection for dilutive issuances. The Series A Warrant and Series B Warrant each contain a mandatory exercise right of ours to force exercise of the warrant if our common stock trades at or above $48.00 for 20 consecutive trading days (subject to certain conditions, including a $150,000 minimum daily volume requirement). The Series C Warrant contains a mandatory exercise right of the Company to force exercise of the warrant if our common stock trades at or above $64.00 for 20 consecutive trading days (subject to certain conditions, including a $150,000 minimum daily volume requirement). The Series B and Series D Warrants have expired unexercised.

In connection with the November 2015 Private Placement, the Company has agreed to deliver to Katalyst Securities LLC, the placement agent for the November 2015 Private Placement (“Katalyst”), warrants exercisable for a period of 5 years from the date of the initial closing to purchase a number of shares of the Company’s common stock equal to 10% of the number of units purchased by any entity specifically formed by a person directly introduced to the Company by Katalyst for the purpose of making an investment in the Company (collectively referred to as “Placement Agent Investors”), who are institutional investors (the “Institutional Placement Agent Investors”) with an exercise price of $48.00, which shall be lowered to $25.60 on the date of the exercise (if any) of all of the Series A Warrants or all of the Series B Warrants (the “Institutional Broker Warrant”). In addition, at each closing, the Company will deliver to Katalyst warrants exercisable for a period of five (5) years from the date of the initial closing to purchase a number of shares of the Company’s common stock equal to 10% of the number of units purchased by any Placement Agent Investors who are not Institutional Placement Agent Investors with exercise prices as apportioned as follows: (x) 25% of such number of warrants shall be exercisable for common stock at an exercise price of $0.32 per share (“Penny Broker Warrant”) and (y) 75% of such number of warrants shall be exercisable for common stock at an exercise price of $19.20 per share (the “IV Broker Warrant” and collectively with the Institutional Broker Warrant and the Penny Broker Warrant, the “ 2015 Broker Warrants”). The 2015 Broker Warrants contain customary provisions, regarding lock-up periods, transferability, registration rights and adjustment in the event of stock splits, subdivision or combination, mergers, etc. The 2015 Broker Warrants may be exercised on a cash or cashless basis.

As of March 27, 2017, the placement agent warrants issued and outstanding in connection with the November 2015 Private Placement entitle their holders to purchase: (a) 8,959 shares of our common stock, with a term of five years (from November 13 or 30, 2015, as applicable) at an exercise price of $0.32 per share. The placement agent warrants contain customary provisions for adjustment in the event of stock splits, subdivision or combination, mergers, etc. Pursuant to the purchase agreement entered into in connection with November 2016 Private Placement (as defined below), we agreed to reduce the exercise prices of certain of our outstanding warrants to purchase shares of common stock that were issued in connection with the November 2015 Private Placement. Effective as of November 18, 2016, the exercise price of each of the Series A Warrants and the Series C Warrants was reduced to $0.32 per share and the exercise price of the Series E Warrants was reduced to $32.00 per share, in each case subject to adjustment as provided in such Warrants. In connection with the November 2016 Private Placement, the Company agreed to reduce the exercise prices of certain of the Company’s outstanding warrants to purchase Common Stock that were issued in connection with the Company’s November 2015 Private Placement of Series B Preferred Stock and warrants. Effective as of November 18, 2016, the exercise price of each of the Series A Warrants and the Series C Warrants was reduced to $0.32 per share and the exercise price of the Series E Warrants was reduced to $32.00 per share, in each case subject to adjustment as provided in such Warrants, pursuant to the Series A Warrant Amendments (the “Series A Warrant Amendments”), the Series C Warrant Amendments (the “Series C Warrant Amendments”) and the Series E Warrant Amendments (the “Series E Warrant Amendments”), respectively.

In a November 2016 private placement, we sold 3,828,754 shares of common stock and warrants to purchase an equivalent number of shares of our common stock, with an exercise price of $12.80 per share (subject to adjustment), for a period of five years from the date of issuance (the “Series F Warrants”), at a purchase price of $6.40 per share of Common Stock and Series F Warrant, resulting in gross proceeds of approximately $24.5 million (the “November 2016 Private Placement”). In connection with the November 2016 Private Placement, we also issued to the placement agents warrants to purchase up to an aggregate of 382,887 shares of our common stock at an exercise price of $6.40 per share. The November 2016 Private Placement was completed in two closings, which took place on November 17, 2016 and November 22, 2016.

In connection with the November 2016 Private Placement, on November 17, 2016, we filed with the Secretary of State of the State of Nevada an Amendment to our Certificate of Designations, Preferences and Rights of Series B Preferred Stock (the “Series B COD Amendment”), originally filed November 13, 2015 with the Secretary of State of the State of Nevada, as corrected by the Certificate of Correction filed November 19, 2015 with the Secretary of State of the State of Nevada (as so corrected, the “Certificate of Designation”). The Series B COD Amendment (i) provided that the Company’s entry into a binding securities purchase agreement, by and among the Company and the investors signatory thereto, in connection with a private placement of the Company’s common stock and warrants, that results in at least $8,000,000 of aggregate gross proceeds to the Company (a “Private Placement”), shall result in the automatic conversion of the Company’s Series B Stock into shares of the Company’s common stock at a conversion price of $18.56 immediately prior to the initial closing of the Private Placement with aggregate gross proceeds to the Company of at least $8 million and (ii) amended the definition of “Excluded Securities” to include the issuance of the Company’s common stock and warrants issued in any Private Placement. As a result of the November 2016 Private Placement, all of the issued and outstanding shares of Series B Stock were converted into an aggregate of 825,962 shares of our common stock on November 17, 2016. The Series B COD Amendment was approved by the “Required Holders” as defined in the Certificate of Designation. As a result of the mandatory conversion of the Series B Stock, the anti-dilution protection for dilutive issuances in the Series A Warrants, the Series C Warrants and the Series E Warrants ceased to be effective pursuant to the terms of such warrants.

Pursuant to the purchase agreement entered into in connection with November 2016 Private Placement, we agreed to reduce the exercise prices of certain of our outstanding warrants to purchase shares of common stock that were issued in connection with the November 2015 Private Placement. Effective as of November 18, 2016, the exercise price of each of the Series A Warrants and the Series C Warrants was reduced to $0.32 per share and the exercise price of the Series E Warrants was reduced to $32.00 per share, in each case subject to adjustment as provided in such Warrants.

In connection with the November 2016 Private Placement, pursuant to a Placement Agency Agreement, dated October 13, 2016 (the “Placement Agency Agreement”), among the Company, Katalyst Securities LLC and GP Nurmenkari Inc. (the “Placement Agents”), the Company has agreed to pay the Placement Agents (i) a cash fee at each closing under the Purchase Agreement equal to ten percent (10%) of each closing’s gross proceeds and (ii) warrants to purchase shares of Common Stock at each closing under the Purchase Agreement equal to ten percent (10%) of the number of shares of Common Stock sold in each closing, with an exercise price of $6.40 per share and a five-year term (the “2016 Broker Warrants” and, together with the 2015 Broker Warrants, the “Broker Warrants”). Such Warrants shall not become exercisable until the Company’s stockholders have approved an amendment to its Articles of Incorporation to increase the number of authorized shares and such amendment is filed in Nevada, which filing occurred on February 24, 2017.

Nevada Anti-Takeover Law and Certain Charter and Bylaw Provisions

Nevada Law

We may in the future become subject to Nevada’s control share laws. A corporation is subject to Nevada’s control share law if it has more than 200 stockholders of record, at least 100 of whom are residents of Nevada, and if the corporation does business in Nevada, including through an affiliated corporation. This control share law may have the effect of discouraging corporate takeovers. The Company currently has fewer than 100 stockholders of record who are residents of Nevada and does not do business in Nevada.

The control share law focuses on the acquisition of a “controlling interest,” which means the ownership of outstanding voting shares that would be sufficient, but for the operation of the control share law, to enable the acquiring person to exercise the following proportions of the voting power of the corporation in the election of directors: (1) one-fifth or more but less than one-third; (2) one-third or more but less than a majority; or (3) a majority or more. The ability to exercise this voting power may be direct or indirect, as well as individual or in association with others.

The effect of the control share law is that an acquiring person, and those acting in association with that person, will obtain only such voting rights in the control shares as are conferred by a resolution of the stockholders of the corporation, approved at a special or annual meeting of stockholders. The control share law contemplates that voting rights will be considered only once by the other stockholders. Thus, there is no authority to take away voting rights from the control shares of an acquiring person once those rights have been approved. If the stockholders do not grant voting rights to the control shares acquired by an acquiring person, those shares do not become permanent non-voting shares. The acquiring person is free to sell the shares to others. If the buyer or buyers of those shares themselves do not acquire a controlling interest, the shares are not governed by the control share law any longer.

If control shares are accorded full voting rights and the acquiring person has acquired control shares with a majority or more of the voting power, a stockholder of record, other than the acquiring person, who did not vote in favor of approval of voting rights for the control shares, is entitled to demand fair value for such stockholder’s shares.

10

Removal of Directors

Our Bylaws provide that a director may be removed only by the affirmative vote of the holders of at least two-thirds of the outstanding shares of our capital stock entitled to vote. In addition, the authorized number of our directors may be changed only by resolution of our directors, and any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. 

The limitations on the ability of our stockholders to change the authorized number of directors, remove directors and fill vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of our company.

Stockholder Action; Special Meeting of Stockholders; Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our Articles of Incorporation and our Bylaws provide that any action required or permitted to be taken by our stockholders at an annual meeting or special meeting of stockholders may only be taken if it is properly brought before such meeting. Our Articles of Incorporation and our Bylaws also provide that, except as otherwise required by law, special meetings of the stockholders can only be called by the chairman of our board of directors, our chief executive officer, our president or our secretary. In addition, our Bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of candidates for election to our board of directors. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors, or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the stockholder's intention to bring such business before the meeting. These provisions could have the effect of delaying until the next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Exclusive Forum

Our Bylaws provide that the appropriate state and federal courts sitting in the State of Nevada shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of our company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to the company or our stockholders, (iii) any action asserting a claim against our company arising pursuant to any provision of the Nevada Revised Statutes or (iv) any action asserting a claim against our company or any of our directors or officers governed by the internal affairs doctrine. Although our Bylaws contain the provision described above, it is possible that a court could rule that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

Registration Rights

We have entered into registration rights agreements with certain holders of our common stock, including our 5% stockholders and their affiliates and entities affiliated with our directors. The registration rights agreement provides these holders the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing.

Registration Rights Agreements

In connection with the November 2015 Private Placement, the Company and certain buyers entered into a registration rights agreement on November 13, 2015. Under the terms of the registration rights agreement, the Company agreed to prepare and file with the SEC a registration statement covering the resale of 150% of the number of shares underlying the Series B Stock, the Investor Warrants and the Broker Warrants) within 30 days following the date of the initial closing. In connection with the Company’s obligations under the registration rights agreement, on December 11, 2015, the Company filed a registration statement on Form S-1, as amended on January 14, 2016 (File No. 333-208502), and subsequently declared effective on January 19, 2016, with the SEC relating to the registrable securities which names each of the holders of the registrable securities as a selling stockholder thereunder.

In connection with the November 2016 Private Placement, the Company and certain buyers entered into a registration rights agreement on November 17, 2016. Under the terms of the registration rights agreement, the Company agreed to register the shares of common stock and the shares of common stock issuable upon exercise of the Series F warrants sold to the buyers pursuant to a securities purchase agreement. The Company was required to file a registration statement for the resale of such securities within 30 days following the closing date. In connection with the Company’s obligations under the registration rights agreement, on December 19, 2016, the Company filed a registration statement on Form S-1, as amended on January 30, 2017 (File No. 333-215159), and subsequently declared effective on February 14, 2017, with the SEC relating to the registrable securities which names each of the holders of the registrable securities as a selling stockholder thereunder.

Form S-3 Registration Rights

In addition, pursuant to each of the registration rights agreements described above, we undertook to register the resale of all the registrable securities on Form S-3 as soon as such form is available, provided that we shall maintain the effectiveness of all registration statements then in effect until such time as a registration statement on Form S-3 covering the resale of all the registrable securities has been declared effective by the SEC and the prospectus contained therein is available for use.

Expenses and Indemnification

Pursuant to the registration rights agreement, we are required to pay all registration expenses, including registration and filing fees, exchange listing fees, and printing expenses and accounting fees, other than any underwriting discounts and commissions, that are related to registration described above. The registration rights agreement contains customary cross-indemnification provisions, pursuant to which we are obligated to indemnify the selling stockholders in the event of material misstatements or omissions in the registration statement attributable to us, and the selling stockholders are obligated to provide an undertaking pursuant to which they will indemnify us for material misstatements or omissions in the registration statement attributable to them.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Philadelphia Stock Transfer, Inc.

NASDAQ Capital Market Listing

If we so indicate in a prospectus supplement, the terms of any debt securities offered under such prospectus supplement may differ from the terms we describe below, and to the extent the terms set forth in a prospectus supplement differ from the terms described below, the terms set forth in the prospectus supplement shall control.

We may sell from time to time, in one or more offerings under this prospectus, debt securities, which may be senior or subordinated. We will issue any such senior debt securities under a senior indenture that we will enter into with a trustee to be named in the senior indenture. We will issue any such subordinated debt securities under a subordinated indenture, which we will enter into with a trustee to be named in the subordinated indenture. We use the term “indentures” to refer to either the senior indenture or the subordinated indenture, as applicable. The indentures will be qualified under the Trust Indenture Act of 1939, as in effect on the date of the indenture. We use the term “debenture trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

12

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all the provisions of the indenture applicable to a particular series of debt securities.

General

Each indenture will provide that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies or units based on or relating to foreign currencies. Neither indenture will limit the amount of debt securities that may be issued thereunder, and each indenture will provide that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution and/or a supplemental indenture, if any, relating to such series.

We will describe in each prospectus supplement the following terms relating to a series of debt securities:

· the title or designation;

· the aggregate principal amount and any limit on the amount that may be issued;

· the currency or units based on or relating to currencies in which debt securities of such series are denominated and the currency or units in which principal or interest or both will or may be payable;

· whether we will issue the series of debt securities in global form, the terms of any global securities and who the depositary will be;

· the maturity date and the date or dates on which principal will be payable;

· the interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the date or dates interest will be payable and the record dates for interest payment dates or the method for determining such dates;

· whether or not the debt securities will be secured or unsecured, and the terms of any secured debt;

· the terms of the subordination of any series of subordinated debt;

· the place or places where payments will be payable;

· our right, if any, to defer payment of interest and the maximum length of any such deferral period;

· the date, if any, after which, and the price at which, we may, at our option, redeem the series of debt securities pursuant to any optional redemption provisions;

· the date, if any, on which, and the price at which we are obligated, pursuant to any mandatory sinking fund provisions or otherwise, to redeem, or at the holder’s option to purchase, the series of debt securities;

· whether the indenture will restrict our ability to pay dividends, or will require us to maintain any asset ratios or reserves;

· whether we will be restricted from incurring any additional indebtedness;

· a discussion on any material or special U.S. federal income tax considerations applicable to a series of debt securities;

· the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof; and

· any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities.

13

We may issue debt securities that provide for an amount less than their stated principal amount to be due and payable upon declaration of acceleration of their maturity pursuant to the terms of the indenture. We will provide you with information on the federal income tax considerations and other special considerations applicable to any of these debt securities in the applicable prospectus supplement.

Conversion or Exchange Rights

We will set forth in the prospectus supplement the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our common stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Information Concerning the Debenture Trustee

The debenture trustee, other than during the occurrence and continuance of an event of default under the applicable indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the debenture trustee under such indenture must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check which we will mail to the holder. Unless we otherwise indicate in a prospectus supplement, we will designate the corporate trust office of the debenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the debenture trustee for the payment of the principal of or any premium or interest on any debt securities which remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of Nevada, except to the extent that the Trust Indenture Act is applicable.

14

Subordination of Subordinated Debt Securities

Our obligations pursuant to any subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of senior indebtedness we may incur. It also does not limit us from issuing any other secured or unsecured debt.

DESCRIPTION OF WARRANTS

General

We may issue warrants to our stockholders to purchase shares of our common stock. We may offer warrants separately or together with one or more debt securities, common stock, rights or purchase contracts, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the certificates relating to the rights of the series of certificates and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights. The following description sets forth certain general terms and provisions of the rights to which any prospectus supplement may relate. The particular terms of the warrant to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the rights so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the warrant, warrant agreement or warrant certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable warrant agreement and warrant certificate for additional information before you decide whether to purchase any of our rights.

We will provide in a prospectus supplement the following terms of the warrants being issued:

· the specific designation and aggregate number of, and the price at which we will issue, the warrants;

· the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;

· whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;

· any applicable material U.S. federal income tax consequences;

· the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;

· the proposed listing, if any, of the warrants or any securities purchasable upon exercise of the warrants on any securities exchange;

15

· if applicable, the date from and after which the warrants and the common stock, preferred stock and/or debt securities will be separately transferable;

· if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;

· information with respect to book-entry procedures, if any;

· the anti-dilution provisions of the warrants, if any;

· any redemption or call provisions;

· whether the warrants may be sold separately or with other securities as parts of units; and

· any additional terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

Each warrant will entitle the holder of rights to purchase for cash the principal amount of shares of common stock or other securities at the exercise price provided in the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement.

Holders may exercise warrants as described in the applicable prospectus supplement. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the shares of common stock or other securities, as applicable, purchasable upon exercise of the rights. If less than all of the warrants issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

Warrant Agent

The warrant agent for any warrants we offer will be set forth in the applicable prospectus supplement.

DESCRIPTION OF RIGHTS

General

We may offer rights separately or together with one or more additional rights, debt securities, common stock, warrants or purchase contracts, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. Each series of rights will be issued under a separate rights agreement to be entered into between us and a bank or trust company, as rights agent.

To the extent that any particular terms of the rights, rights agreement or rights certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable rights agreement and rights certificate for additional information before you decide whether to purchase any of our rights.

Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement.

Holders may exercise rights as described in the applicable prospectus supplement.

17

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and for us to sell to holders, a specific or variable number of our debt securities, shares of common stock, warrants or rights, or securities of an entity unaffiliated with us, or any combination of the above, at a future date or dates. Alternatively, the purchase contracts may obligate us to purchase from holders, and obligate holders to sell to us, a specific or variable number of our debt securities, shares of common stock, warrants, rights or other property, or any combination of the above. The price of the securities or other property subject to the purchase contracts may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula described in the purchase contracts. We may issue purchase contracts separately or as a part of units each consisting of a purchase contract and one or more of our other securities described in this prospectus or securities of third parties, including U.S. Treasury securities, securing the holder’s obligations under the purchase contract. The purchase contracts may require us to make periodic payments to holders or vice versa and the payments may be unsecured or pre-funded on some basis. The purchase contracts may require holders to secure the holder’s obligations in a manner specified in the applicable prospectus supplement.

The applicable prospectus supplement will describe the terms of any purchase contracts in respect of which this prospectus is being delivered, including, to the extent applicable, the following:

· whether the purchase contracts obligate the holder or us to purchase or sell, or both purchase and sell, the securities subject to purchase under the purchase contract, and the nature and amount of each of those securities, or the method of determining those amounts;

· whether the purchase contracts are to be prepaid;

· whether the purchase contracts are to be settled by delivery, or by reference or linkage to the value, performance or level of the securities subject to purchase under the purchase contract;

· any acceleration, cancellation, termination or other provisions relating to the settlement of the purchase contracts;

· any applicable U.S. federal income tax considerations; and

· whether the purchase contracts will be issued in fully registered or global form.

The preceding description sets forth certain general terms and provisions of the purchase contracts to which any prospectus supplement may relate. The particular terms of the purchase contracts to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the purchase contracts so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the purchase contracts described in a prospectus supplement differ from any of the terms described above, then the terms described above will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable purchase contract for additional information before you decide whether to purchase any of our purchase contracts.

DESCRIPTION OF UNITS

The following description, together with the additional information that we include in any applicable prospectus supplements summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

We will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

18

General

We may issue units consisting of common stock, one or more debt securities, warrants, rights or purchase contacts for the purchase of common stock and/or debt securities in one or more series, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each security included in the unit. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

· the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

· any provisions of the governing unit agreement that differ from those described below; and

· any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those set forth in any prospectus supplement or as described under “Description of Capital Stock,” “Description of Debt Securities,” “Description of Warrants,” “Description of Rights” and “Description of Purchase Contracts” will apply to each unit, as applicable, and to any common stock, debt security, warrant, right or purchase contract included in each unit, as applicable.

Unit Agent

The name and address of the unit agent for any units we offer will be set forth in the applicable prospectus supplement.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

Provisions of Nevada Law Governing Business Combinations

Nevada has a business combination law, which prohibits certain business combinations between Nevada corporations and “interested stockholders” for two years after the interested stockholder first becomes an interested stockholder, unless the corporation’s board of directors approves the combination in advance. For purposes of Nevada law, an interested stockholder is any person who is: (a) the beneficial owner, directly or indirectly, of 10% or more of the voting power of the outstanding voting shares of the corporation, or (b) an affiliate or associate of the corporation and at any time within the previous two years was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then-outstanding shares of the corporation. The definition of “business combination” contained in the statute is sufficiently broad to cover virtually any kind of transaction that would allow a potential acquirer to use the corporation’s assets to finance the acquisition or otherwise to benefit its own interests rather than the interests of the corporation and its other stockholders.

19

The effect of Nevada’s business combination law is to potentially discourage a party interested in taking control of the Company from doing so if it cannot obtain the approval of our Board.

Limitations on Liability and Indemnification of Officers and Directors

Under the Nevada Revised Statutes, our directors and officers are not individually liable to us or our stockholders for any damages as a result of any act or failure to act in their capacity as an officer or director unless it is proven that:

· His act or failure to act constituted a breach of his fiduciary duty as a director or officer; and

· His breach of these duties involved intentional misconduct, fraud or a knowing violation of law.

Nevada law allows corporations to provide broad indemnification to its officers and directors. At the present time, our Articles of Incorporation and our amended and restated by-laws also provide for broad indemnification of our current and former directors, trustees, officers, employees and other agents. We have also entered into indemnification agreements with each of our directors and officers, pursuant to which we have agreed to indemnify such individuals against certain liabilities that arise by reason of their status as directors and officers to the fullest extent permitted by applicable law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons, we have been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

LEGAL MATTERS

Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., New York, New York, will pass upon the validity of the issuance of the securities to be offered by this prospectus.
