BIO-PATH HOLDINGS, INC.

Notes to the Unaudited Condensed Consolidated Financial Statements
for the Period Ended March 31, 2019

Unless the context requires otherwise, references in these Notes to the Consolidated Financial Statements to “we,” “our,” “us,” “the Company” and “Bio-Path” refer to Bio-Path Holdings, Inc. and its subsidiary. Bio-Path Holdings, Inc.’s wholly-owned subsidiary, Bio-Path, Inc., is sometimes referred to herein as “Bio-Path Subsidiary.”

The accompanying interim financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, do not include all information and footnotes necessary for a complete presentation of the Company’s financial position, results of operations, cash flows, and stockholders’ equity in conformity with generally accepted accounting principles. In the opinion of management, all adjustments considered necessary for a fair presentation of the results of operations and financial position have been included and all such adjustments are of a normal recurring nature. The unaudited quarterly financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K of the Company as of and for the fiscal year ended December 31, 2018. The results of operations for the period ended March 31, 2019, are not necessarily indicative of the results for a full-year period.

1. Organization and Business

The Company is a clinical and preclinical stage oncology focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a neutral charged lipid bilayer. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. DNAbilize® is a registered trademark of the Company. Using DNAbilize® as a platform for drug development and manufacturing, we currently have three antisense drug candidates in development to treat at least five different cancer disease indications.

Bio-Path Subsidiary was founded in May 2007 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter and had no current operations. The prior name of Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. The Company’s operations to date have been limited to organizing and staffing the Company, acquiring, developing and securing its technology and undertaking product development for a limited number of product candidates.

In June 2015, the Company established an “at the market” (“ATM”) program through which it may offer and sell up to $25.0 million of its common stock from time to time, at Bio-Path’s discretion, through an investment banking firm, acting as sales agent. Sales of Bio-Path common stock under the ATM program will be made directly on or through The Nasdaq Capital Market, among other methods. The ATM program may be terminated by either the investment banking firm or the Company upon ten days’ notice. We are subject to certain restrictions on our ability to offer and sell shares of our common stock under the ATM program. To date, the Company has not offered or sold any shares of its common stock under the ATM program.

On September 20, 2018, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell an aggregate of 98,454 shares of our common stock and pre-funded warrants to purchase up to 14,624 shares of our common stock for gross proceeds of approximately $1.5 million under our effective shelf registration statement on Form S-3 (File No. 333-2152051) (the “2017 Shelf Registration Statement”), which became effective on January 9, 2017 (the “2018 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 113,077 shares of our common stock (the “2018 Private Placement”). Additionally, we issued warrants to purchase up to 6,785 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the 2018 Registered Direct Offering and the 2018 Private Placement. The 2018 Registered Direct Offering and the 2018 Private Placement closed on September 25, 2018. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.2 million.

7

On January 14, 2019, we entered into an underwriting agreement with H.C. Wainwright & Co., LLC relating to an underwritten public offering of 429,616 shares of our common stock for gross proceeds of approximately $1.1 million under the 2017 Shelf Registration Statement (the “2019 Underwritten Offering”). The offering price to the public in the 2019 Underwritten Offering was $2.60 per share, and H.C. Wainwright & Co., LLC agreed to purchase the shares in the 2019 Underwritten Offering from the Company pursuant to the underwriting agreement at a price of $2.418 per share. Additionally, we issued warrants to purchase up to 25,777 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as underwriter in connection with the 2019 Underwritten Offering. The 2019 Underwritten Offering closed on January 17, 2019. The net proceeds to the Company from the 2019 Underwritten Offering, after deducting the underwriting discounts and commissions and expenses and the Company’s estimated offering expenses, and excluding the proceeds, if any, from the exercise of the underwriter warrants, were approximately $0.9 million.

On January 17, 2019, we effected a reverse stock split of our outstanding shares of common stock at a ratio of 1-for-20, and our common stock began trading on the split-adjusted basis on the Nasdaq Capital Market at the commencement of trading on January 18, 2019. All common stock share and per share amounts in our consolidated financial statements have been adjusted to give effect to the 1-for-20 reverse stock split.

On January 18, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 648,233 shares of our common stock for gross proceeds of approximately $1.7 million under the 2017 Shelf Registration Statement (the “January 2019 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 324,117 shares of our common stock (the “January 2019 Private Placement”). Additionally, we issued warrants to purchase up to 38,894 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the 2019 Registered Direct Offering and the 2019 Private Placement. The 2019 Registered Direct Offering and the 2019 Private Placement closed on January 23, 2019. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.5 million.

On March 12, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 712,910 shares of our common stock for gross proceeds of approximately $18.5 million under the 2017 Shelf Registration Statement (the “March 2019 Registered Direct Offering”). Additionally, we issued warrants to purchase up to 42,775 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the March 2019 Registered Direct Offering. The March 2019 Registered Direct Offering closed on March 14, 2019. The net proceeds to us from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $17.0 million.

As the Company has not begun its planned principal operations of commercializing a product candidate, the Company’s activities are subject to significant risks and uncertainties, including the potential requirement to secure additional funding, the outcome of the Company’s clinical trials, and failing to operationalize the Company’s current drug candidates before another company develops similar products.

2. Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability initially measured at the present value of the lease payments on the balance sheet for all leases with terms longer than 12 months. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In 2018, the FASB issued ASU 2018-01 and ASU 2018-11, which collectively adds two practical expedients and provides a second modified retrospective transition method in the year of adoption. Management adopted the new standard on January 1, 2019 using the modified retrospective transition approach with no restatement of prior periods or cumulative adjustment to accumulated deficit. We elected the “package of practiced expedients”, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and indirect costs. We also elected the short-term lease exemption and therefore do not recognize a ROU assets or corresponding liability for lease agreements with an original term of 12 months or less. Consequently, prior year financials statements have not been updated and the disclosures required under the new standard have not been provided for periods prior to the adoption date. Upon adoption of the new standards, the Company recognized $0.1 million for ROU assets and corresponding lease liabilities on the consolidated balance sheet related to leases for office and lab space. The adoption of these ASU’s on January 1, 2019 did not have a significant impact on our consolidated financial statements.

8

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The new standard eliminates certain disclosure requirements for fair value measurements for all entities, requires public entities to disclose certain new information and modifies some disclosure requirements. This standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Management is currently evaluating the impact of future adoption of the new standard on the Company’s consolidated financial statements.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606. The new standard provides guidance on how to assess whether certain transactions between collaborative arrangement participants should be accounted for within the revenue recognition standard. The update also provides more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. The new standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted. The Company early adopted this standard effective December 31, 2018 and notes that it did not a significant impact on our consolidated financial statements as the Company currently does not have significant collaborative agreements in place.

Management has reviewed all other recently issued pronouncements and has determined they will have no material impact on the Company’s consolidated financial statements.

3. Prepaid Drug Product for Testing

Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future clinical development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. The Company made payments to its contract drug manufacturing and raw material suppliers totaling $0.3 million through 2018 pursuant to drug supply contracts for the manufacture and delivery of prexigebersen for testing in two Phase 2 clinical trials and Bcl-2 for testing in a Phase 1 clinical trial. This amount was carried on the Balance Sheet as of December 31, 2018 at cost as Prepaid Drug Product for Testing. The Company incurred additional installment costs during 2019, with advanced payments totaling $0.4 million, which are carried on the Balance Sheet as of March 31, 2019 as Prepaid Drug Product for Testing (See Note 9).

The 2007 Plan expired by its terms in January 2018, and no awards were made under the 2007 Plan from the approval of the 2017 Plan on December 21, 2017 until the expiration of the 2007 Plan. The 2017 Plan provides for the grant of Incentive Stock Options, Non-Qualified Stock Options, Restricted Shares, Restricted Share Units, Stock Appreciation Rights, Performance-Based Awards and other stock-based awards, or any combination of the foregoing to the Company’s employees, non-employee directors and consultants. As of December 31, 2018, the total number of shares reserved and available for grant and issuance pursuant to the 2017 Plan was 60,000 shares, subject to the terms of the 2017 Plan. Under the 2017 Plan, the exercise price of awards is determined by the Board of Directors or the compensation committee of the Board of Directors, and for options intended to qualify as qualified Incentive Stock Options, may not be less than the fair market value as determined by the closing stock price at the date of the grant. Each option and award under the 2017 Plan shall vest and expire as determined by the Board of Directors or the compensation committee. Options expire no later than ten years from the date of grant. All grants provide for accelerated vesting if there is a change of control, as defined in the 2017 Plan.

Stock-based compensation expense for the three months ended March 31, 2019 and March 31, 2018 was $0.2 million and $0.1 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for both the three months ended March 31, 2019 and March 31, 2018 was $0.1 million. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended March 31, 2019 and March 31, 2018 was $25,000 and $20,000, respectively.

The Company utilized the Black-Scholes valuation model for estimating the fair value of the stock options granted, with the following weighted-average assumptions for options granted in the three months ended March 31, 2019 and 2018, respectively:

	2019			2018
Risk-free interest rate		2.23	%		2.59	%
Expected volatility		126	%		95	%
Expected term in years		6.0			6.1
Dividend yield		-%			-%

The following summary represents option activity under the Company’s stock-based compensation plans for the three months ended March 31, 2019:

				Weighted-
				Average
				Exercise
	Options			Price
	(in thousands)
Outstanding at December 31, 2018		37		$	112.60

Outstanding at March 31, 2019		71			67.26
Exercisable at March 31, 2019		16			186.16

As of March 31, 2019, the aggregate intrinsic value of outstanding stock options was $0.1 million. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on March 31, 2019 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2019. This amount changes based on the fair market value of the Company’s stock.

As of March 31, 2019, unamortized stock-based compensation expense for all outstanding options was $1.0 million, which is expected to be recognized over a weighted average vesting period of 2.4 years.

9. Commitments and Contingencies

Drug Supplier Project Plan – The amounts paid for manufacture of the Company’s Grb2 drug substance, prexigebersen, Bcl-2 drug substance and BP1002 drug product that have not been expensed total $0.4 million and are carried on the balance sheet as of March 31, 2019 as Prepaid Drug Product for Testing (See Note 3). Total commitments for the Company’s drug supplier project plan are $1.5 million as of March 31, 2019, comprised of $1.0 million to the manufacturer of prexigebersen and BP1002, $0.4 million for manufacture of our Grb2 and Bcl-2 drug substance and $0.1 million for manufacturing development. We expect to incur $0.9 million of these commitments over the next 12 months.

10. Leases

In April 2014, the Company entered into a five-year lease agreement for administrative office space located in Bellaire, Texas. The term of the lease began on August 1, 2014 and terminates on July 31, 2019.

In April 2016, the Company entered into a three-year lease agreement for lab space located in Bellaire, Texas. The term of lease began on May 1, 2016 and terminates on April 30, 2019 and requires Bio-Path to pay $2,500 per month over the term of the lease. In December 2018, we entered into an amendment to the agreement with the term of the extension beginning on May 1, 2019 and terminating on April 30, 2022 and will require Bio-Path to pay $2,575 per month over the term.

At the inception of an agreement, the Company determines if the agreement is a lease based on the unique facts and circumstances in each agreement. Lease classification, recognition, and measurement are then determined at the lease commencement date. For agreements that contain a lease, we identify lease and non-lease components, determine the consideration in the contract, determine whether the lease is an operating or financing lease and recognize ROU assets and lease liabilities. Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable so we use an incremental borrowing rate based on the information available at the lease commencement date, which represents an estimated rate that would be incurred to borrow over a similar term in a similar economic environment. The incremental borrowing rate utilized on our lease liabilities as of March 31, 2019 was 8.0%.

Our current leases include options to renew which can impact the lease term. The exercise of these options is at the Company’s discretion and we do not include any of these options within the expected lease term as we are not reasonably certain we will exercise these options. Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis within our consolidated financial statements. Our leases are included in ROU assets, current portion of lease liabilities and noncurrent lease liabilities in our consolidated balance sheet as of March 31, 2019.

 The following table summarizes our operating lease assets and liabilities as of March 31, 2019:

Overview

We are a clinical and preclinical stage oncology focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a neutral charged lipid bilayer. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. Through testing in numerous animal studies and treatment in over 70 patients, the Company’s DNAbilize® drug candidates have demonstrated an excellent safety profile. DNAbilize® is a registered trademark of the Company.

Using DNAbilize® as a platform for drug development and manufacturing, we currently have three antisense drug candidates in development to treat at least five different cancer disease indications. Our lead drug candidate, prexigebersen (pronounced prex” i je ber’ sen), is in the efficacy portion of a Phase 2 clinical trial for acute myeloid leukemia (AML) in combination with low-dose cytarabine (LDAC) and in combination with decitabine. On March 6, 2019, we announced intended amendments to this Phase 2 clinical trial to, among other things, add prexigebersen in combination with decitabine for myelodysplastic syndrome and close prexigebersen in combination with LDAC. In addition, preclinical efficacy studies are underway for triple combination prexigebersen, decitabine and venetoclax in AML. Prexigebersen is also being studied in the safety portion of a Phase 2a clinical trial for chronic myeloid leukemia in combination with dasatinib. Prexigebersen was shown to enhance chemotherapy efficacy in preclinical solid tumor models, such as ovarian cancer, and we intend to file an Investigational New Drug (IND) application for prexigebersen in solid tumors in 2019.

Our second drug candidate, Liposomal Bcl-2 (“BP1002”), targets the protein Bcl-2, which is responsible for driving cell survival in up to 60% of all cancers. We are currently preparing an IND application for BP1002 after completing additional IND enabling studies. We intend to initiate a Phase 1 clinical trial of BP1002 in refractory/relapsed lymphoma and chronic lymphocytic leukemia patients once we receive approval from the U.S. Food and Drug Administration (FDA).

Our third drug candidate, Liposomal Stat3 (“BP1003”), targets the Stat3 protein and is currently in preclinical development as a potential treatment of pancreatic cancer, non-small cell lung cancer (NSCLC) and AML. Preclinical models have shown BP1003 to inhibit cell viability and STAT3 protein expression in NSCLC and AML cell lines. Further, BP1003 successfully penetrated pancreatic tumors and significantly enhanced the efficacy of gemcitabine, a treatment for patients with advanced pancreatic cancer, in a pancreatic patient derived tumor model. Our lead indication for BP1003 is pancreatic cancer due to the severity of this disease and the lack of effective, life-extending treatments. We intend to complete IND enabling studies of BP1003 in 2019 and to file an IND application for a Phase 1 clinical trial of BP1003 for the treatment of solid tumors, including pancreatic cancer in 2020.

Our DNAbilize® technology-based products are available for out-licensing or partnering. We intend to apply our drug delivery technology template to new disease-causing protein targets as a means to develop new nanoparticle antisense RNAi drug candidates. We have a new product identification template in place to define a process of scientific, preclinical, commercial and intellectual property evaluation of potential new drug candidates for inclusion into our drug product development pipeline. As we expand, we will look at indications where a systemic delivery is needed and antisense RNAi nanoparticles can be used to slow, reverse or cure a disease, either alone or in combination with another drug. On July 19, 2017, we announced that the United States Patent and Trademark Office issued a notice of allowance for claims related to DNAbilize®, including its use in the treatment of cancers, autoimmune diseases and infectious diseases.

13

We have certain intellectual property as the basis for our current drug products in clinical development, prexigebersen, BP1002 and BP1003. We are developing RNAi antisense nanoparticle drug candidates based on our own patented technology to treat cancer and autoimmune disorders where targeting a single protein may be advantageous and result in reduced patient adverse effects as compared to small molecule inhibitors with off-target and non-specific effects. We have composition of matter and method of use intellectual property for the design and manufacture of antisense RNAi nanoparticle drug products.

On January 14, 2019, we entered into an underwriting agreement with H.C. Wainwright & Co., LLC relating to an underwritten public offering of 429,616 shares of our common stock for gross proceeds of approximately $1.1 million under our shelf registration statement on Form S-3 (File No. 333-215205), which became effective on January 9, 2017 (the “2019 Underwritten Offering”). The offering price to the public in the 2019 Underwritten Offering was $2.60 per share, and H.C. Wainwright & Co., LLC agreed to purchase the shares in the 2019 Underwritten Offering from the Company pursuant to the underwriting agreement at a price of $2.418 per share. Additionally, we issued warrants to purchase up to 25,777 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as underwriter in connection with the 2019 Underwritten Offering. The 2019 Underwritten Offering closed on January 17, 2019. The net proceeds to the Company from the 2019 Underwritten Offering, after deducting the underwriting discounts and commissions and expenses and the Company’s estimated offering expenses, and excluding the proceeds, if any, from the exercise of the underwriter warrants, were approximately $0.9 million.

On January 18, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 648,233 shares of our common stock for gross proceeds of approximately $1.7 million under our effective shelf registration statement on Form S-3 (File No. 333-215205), which became effective on January 9, 2017 (the “January 2019 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 324,117 shares of our common stock (the “January 2019 Private Placement”). Additionally, we issued warrants to purchase up to 38,894 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the January 2019 Registered Direct Offering and the January 2019 Private Placement. The January 2019 Registered Direct Offering and the January 2019 Private Placement closed on January 23, 2019. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.5 million.

On March 12, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 712,910 shares of our common stock for gross proceeds of approximately $18.5 million under our effective shelf registration statement on Form S-3 (File No. 333-215205), which became effective on January 9, 2017 (the “March 2019 Registered Direct Offering”). Additionally, we issued warrants to purchase up to 42,775 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the March 2019 Registered Direct Offering. The March 2019 Registered Direct Offering closed on March 14, 2019. The net proceeds to us from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $17.0 million.

As of March 31, 2019, we had an accumulated deficit of $49.3 million. Our net loss was $1.5 million and $1.9 million for the three months ended March 31, 2019 and 2018, respectively. We expect to continue to incur significant operating losses, and we anticipate that our losses may increase substantially as we expand our drug development programs and commercialization efforts. To achieve profitability, we must enter into license or development agreements with third parties, or successfully develop and obtain regulatory approval for one or more of our drug candidates and effectively commercialize any drug candidates we develop. In addition, if we obtain regulatory approval of one or more of our drug candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Even if we succeed in developing and commercializing one or more of our drug candidates, we may not be able to generate sufficient revenue and we may never be able to achieve or sustain profitability. We expect to finance our foreseeable cash requirements through cash on hand, cash from operations, debt financings and public or private equity offerings. We may seek to access the public or private equity markets whenever conditions are favorable; however, there can be no assurance that we will be able to raise additional capital when needed or on terms that are favorable to us, if at all. Additionally, we may seek collaborations and license arrangements for our drug candidates. We currently have no lines of credit or other arranged access to debt financing.

Company History and Available Information

The Company was incorporated in May 2000 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter and had no current operations. The prior name of the Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. On March 10, 2014, our common stock ceased trading on the OTCQX and commenced trading on the Nasdaq Capital Market under the ticker symbol “BPTH.” Effective December 31, 2014, we changed our state of incorporation from Utah to Delaware through a statutory conversion pursuant to the Utah Revised Business Corporation Act and the Delaware General Corporation Law. Our principal executive offices are located at 4710 Bellaire Boulevard, Suite 210, Bellaire, Texas 77401, and our telephone number is (832) 742-1357.

On February 8, 2018, we effected a reverse stock split of our outstanding shares of common stock at a ratio of 1-for-10, and our common stock began trading on the split-adjusted basis on the Nasdaq Capital Market at the commencement of trading on February 9, 2018. In addition, on January 17, 2019, we effected a reverse stock split of our outstanding shares of common stock at a ratio of 1-for-20, and our common stock began trading on the split-adjusted basis on the Nasdaq Capital Market at the commencement of trading on January 18, 2019. All common stock share and per share amounts in this Quarterly Report on Form 10-Q have been adjusted to give effect to both the 1-for-10 reverse stock split and the 1-for-20 reverse stock split, retrospectively.

Recent Accounting Pronouncements

See Note 2 to the Unaudited Condensed Consolidated Financial Statements for a discussion of the impact of a new accounting standards update on the Company’s condensed consolidated financial statements.

Financial Operations Overview

Revenue

We have not generated significant revenues to date. Our ability to generate revenues from our drug candidates, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our drug candidates.

In the future, we may generate revenue from a combination of product sales, third-party grants, service agreements, strategic alliances and licensing arrangements. We expect that any revenue we generate will fluctuate due to the timing and amount of services performed, milestones achieved, license fees earned and payments received upon the eventual sales of our drug candidates, in the event any are successfully commercialized. If we fail to complete the development of any of our drug candidates or obtain regulatory approval for them, our ability to generate future revenue will be adversely affected.

Research and development expenses

Research and development expenses consist of costs associated with our research activities, including the development of our drug candidates. Our research and development expenses consist of:

· expenses related to research and development personnel, including salaries and benefits, travel and stock-based compensation;

· external research and development expenses incurred under arrangements with third parties, such as contract research organizations, clinical investigative sites, laboratories, manufacturing organizations and consultants; and

· costs of materials used during research and development activities.

Costs and expenses that can be clearly identified as research and development are charged to expense as incurred in accordance with generally accepted accounting policies (“GAAP”). Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed. If the goods will not be delivered, or services will not be rendered, then the capitalized advance payment is charged to expense.

15

We expect research and development expenses associated with the completion of the associated clinical trials to be substantial and to increase over time. The successful development of our drug candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete development of our drug candidates or the period, if any, in which material net cash inflows from our drug candidates may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

· the rate of progress, results and costs of completion of ongoing clinical trials of our drug candidates;

· the size, scope, rate of progress, results and costs of completion of any potential future clinical trials and preclinical trials of our drug candidates that we may initiate;

· competing technological and market developments;

· the performance of third-party manufacturers and suppliers;

· the ability of our drug candidates, if they receive regulatory approval, to achieve market success; and

· disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our drug candidates.

A change in the outcome of any of these variables with respect to the development of a drug candidate could mean a significant change in the costs and timing associated with the development of that drug candidate. For example, if the FDA or other regulatory authority were to require us to conduct clinical trials beyond those which we currently anticipate will be required for the completion of clinical development of a drug candidate or if we experience significant delays in enrollment in any clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

General and administrative expenses

Our general and administrative expenses consist primarily of salaries and benefits for management and administrative personnel, professional fees for legal, accounting and other services, travel costs and facility-related costs such as rent, utilities and other general office expenses.

Results of Operations

Comparisons of the Three Months Ended March 31, 2019 to the Three Months Ended March 31, 2018

Research and Development Expense. Our research and development expense for the three months ended March 31, 2019 was $0.4 million, a decrease of $0.5 million compared to the three months ended March 31, 2018. The decrease in research and development expense was primarily due to decreased clinical trial expenses as we modified operations between Stage 1 and Stage 2 of our Phase 2 clinical trial in AML to include venetoclax combination treatment with prexigebersen. The following table sets forth our research and development expenses (in thousands):

	Three Months Ended
	March 31,
	2019		2018
Research and development expense	$	373	$	912
Non-cash stock-based compensation expense		25		20
Total research and development expense	$	398	$	932

General and Administrative Expense. Our general and administrative expense for the three months ended March 31, 2019 was $1.1 million, an increase of $0.1 million compared to the three months ended March 31, 2018. The increase in general and administrative expense was primarily due to increased legal and insurance expenses. The following table sets forth our general and administrative expenses (in thousands):

	Three Months Ended
	March 31,
	2019		2018
General and administrative expense	$	990	$	883
Non-cash stock-based compensation expense		132		104
Total general and administrative expense	$	1,122	$	987

16

Net Operating Loss. Our net loss from operations for the three months ended March 31, 2019 was $1.5 million, a decrease of $0.4 million compared to the three months ended March 31, 2018.

Net Loss. Our net loss for the three months ended March 31, 2019 was $1.5 million, a decrease of $0.4 million compared to the three months ended March 31, 2018.

Net Loss per Share. Net loss per share, both basic and diluted, was $0.89 per share for the three months ended March 31, 2019, compared to $3.38 per share for the three months ended March 31, 2018. Net loss per share is calculated using the weighted average number of shares of common stock outstanding during the applicable periods and excludes stock options and warrants because they are antidilutive.

Liquidity and Capital Resources

Overview

We have not generated significant revenues to date. Since our inception, we have funded our operations primarily through public and private offerings of our capital stock and other securities. We expect to finance our foreseeable cash requirements through cash on hand, cash from operations, debt financings and public or private equity offerings. We may seek to access the public or private equity markets whenever conditions are favorable; however, there can be no assurance that we will be able to raise additional capital when needed or on terms that are favorable to us, if at all. Additionally, we may seek collaborations and license arrangements for our drug candidates. We currently have no lines of credit or other arranged access to debt financing.

We had a cash balance of $19.3 million at March 31, 2019, an increase of $18.3 million compared to December 31, 2018. We believe that our available cash at March 31, 2019 will be sufficient to meet obligations and fund our liquidity and capital expenditure requirements for at least the next 12 months.

Cash Flows

Operating Activities. Net cash used in operating activities for the three months ended March 31, 2019 was $2.0 million. Net cash used in operating activities consisted primarily of the net loss for the period of $1.5 million, an increase in prepaid expenses and other current assets of $0.7 million and a decrease in current liabilities of $0.1 million. Our net cash used in operating activities is partially offset by stock-based compensation expense of $0.2 million and depreciation expense of $0.1 million.

Financing Activities. Net cash provided by financing activities for the three months ended March 31, 2019 was $20.3 million. Net cash provided by financing activities consisted primarily of net proceeds of $19.4 million from the 2019 Underwritten Offering, the January 2019 Registered Direct Offering and January 2019 Private Placement and the March 2019 Registered Direct Offering, each as described below, as well as net proceeds of $0.9 million from the exercise of warrants to purchase shares of our common stock.

2017 Shelf Registration Statement

On December 20, 2016, we filed a shelf registration on Form S-3 with the SEC, which was declared effective by the SEC on January 9, 2017 (File No. 333-215205) (the “2017 Shelf Registration Statement”), at which time the offering of unsold securities under a previous shelf registration statement on Form S-3 filed with the SEC, which was declared effective by the SEC on January 13, 2014 (File No. 333-192102) (the “2014 Shelf Registration Statement”), was deemed terminated pursuant to Rule 415(a)(6) under the Securities Act. The 2017 Shelf Registration Statement was filed to register the offering, issuance and sale of (i) up to $125.0 million of our common stock, preferred stock, warrants to purchase common stock or preferred stock or any combination thereof, either individually or in units, including offers and sales of our common stock under the Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor Fitzgerald”) described below and (ii) up to 27,209 shares of our common stock pursuant to the exercise of warrants that were issued in a registered direct offering in 2014 and a registered direct offering in 2016. The foregoing does not constitute an offer to sell or the solicitation of an offer to buy securities, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of that jurisdiction.

17

“At the Market” Offering

On June 24, 2015, we entered into the Sales Agreement with Cantor Fitzgerald, as sales agent, pursuant to which we may offer and sell, from time to time, through Cantor Fitzgerald, shares of our common stock. Sales of shares of common stock under the Sales Agreement will be made pursuant to the 2017 Shelf Registration Statement and a related prospectus filed with the SEC on January 10, 2017, for an aggregate offering price of up to $25.0 million. Under the Sales Agreement, Cantor Fitzgerald may sell shares by any method deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act. We will pay Cantor Fitzgerald a commission of 3.4% of the aggregate gross proceeds from each sale of shares under the Sales Agreement and have agreed to provide Cantor Fitzgerald with customary indemnification and contribution rights. We have also agreed to reimburse Cantor Fitzgerald for certain specified expenses. The Sales Agreement may be terminated by either Cantor Fitzgerald or the Company upon ten days’ notice. We are subject to certain restrictions on our ability to offer and sell shares of our common stock under the Sales Agreement. To date, we have not offered or sold any shares of common stock under the Sales Agreement.

2018 Registered Direct Offering and 2018 Private Placement

On September 20, 2018, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 98,454 shares of our common stock and pre-funded warrants to purchase up to 14,624 shares of our common stock for gross proceeds of approximately $1.5 million under the 2017 Shelf Registration Statement (the “2018 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 113,077 shares of our common stock (the “2018 Private Placement”). Additionally, we issued warrants to purchase up to 6,785 shares of our common stock in a private placement to H.C.

Future Capital Requirements

We expect to continue to incur significant operating expenses in connection with our ongoing activities, including conducting clinical trials, manufacturing and seeking regulatory approval of our drug candidates prexigebersen, BP1002 and BP1003. Accordingly, we will continue to require substantial additional capital to fund our projected operating requirements. Such additional capital may not be available when needed or on terms favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current and future operating plan. There can be no assurance that we will be able to continue to raise additional capital through the sale of our securities in the future. Our future capital requirements may change and will depend on numerous factors, which are discussed in detail in “Item 1A. Risk Factors” to Part I of our Annual Report on Form 10-K as of the fiscal year ended December 31, 2018. For more information, see Note 1 to the Unaudited Condensed Consolidated Financial Statements included herein.

Off-Balance Sheet Arrangements

As of March 31, 2019, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP in the United States has required the management of the Company to make assumptions, estimates and judgments that affect the amounts reported in the financial statements, including the notes thereto, and related disclosures of commitments and contingencies, if any. We consider our critical accounting policies to be those that require the more significant judgments and estimates in the preparation of financial statements. Except as disclosed below, there have been no significant changes to our critical accounting policies from those disclosed in Note 2 to our Consolidated Financial Statements included in our Annual Report on Form 10-K as of the year ended December 31, 2018.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Effective January 1, 2019 we adopted ASU No. 2016-02, Leases. Management has determined that the Company’s ROU asset and lease liability did not have a significant impact on the Company’s consolidated financial statements. See Note 2, Recent Accounting Pronouncements, and Note 10, Leases, of the Notes to Consolidated Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q for additional details regarding the impact of the adoption of this standard.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not applicable.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

It is management’s responsibility to establish and maintain adequate disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Disclosure controls and procedures are controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including the company’s principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Our management, including our Chief Executive Officer (who is also our Chief Financial Officer), has reviewed and evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Following this review and evaluation, due to the material weakness in our internal control over financial reporting discussed below, our management determined that as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were not effective as it relates to an input in our clinical trial expense accrual to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

19

As previously disclosed under “Item 9A. Controls and Procedures” to Part II of our Annual Report on Form 10-K as of the fiscal year ended December 31, 2018, our management identified a material weakness in our internal control over financial reporting relating to the design of our controls to prevent a misstatement resulting from the information and communication between our clinical and finance personnel as it relates to an input for our clinical trial expense accrual. Our management is committed to the planning and implementation of remediation efforts to address the material weakness in our internal control over financial reporting. During the three months ended March 31, 2019, we designed processes and internal controls to improve communication between our clinical and finance personnel in addition to using a report to substantiate the input used in our clinical trial expense accrual. These remediation efforts are intended both to address the identified material weakness and to enhance our overall financial control environment. When fully implemented and operational, our management believes that these measures will appropriately remediate the material weakness and strengthen our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

Other than the change to address the material weakness discussed above under “Evaluation of Disclosure Controls and Procedures,” there were no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Business

1. Organization and Business

The Company is a clinical and preclinical stage oncology focused RNAi nanoparticle drug development company utilizing a novel technology that achieves systemic delivery for target specific protein inhibition for any gene product that is over-expressed in disease. Our drug delivery and antisense technology, called DNAbilize®, is a platform that uses P-ethoxy, which is a deoxyribonucleic acid (DNA) backbone modification that is intended to protect the DNA from destruction by the body’s enzymes when circulating in vivo, incorporated inside of a neutral charged lipid bilayer. We believe this combination allows for high efficiency loading of antisense DNA into non-toxic, cell-membrane-like structures for delivery of the antisense drug substance into cells. In vivo, the DNAbilize® delivered antisense drug substances are systemically distributed throughout the body to allow for reduction or elimination of target proteins in blood diseases and solid tumors. DNAbilize® is a registered trademark of the Company. Using DNAbilize® as a platform for drug development and manufacturing, we currently have three antisense drug candidates in development to treat at least five different cancer disease indications.

Bio-Path Subsidiary was founded in May 2007 as a Utah corporation. In February 2008, Bio-Path Subsidiary completed a reverse merger with the Company, which at the time was traded over the counter and had no current operations. The prior name of Company was changed to Bio-Path Holdings, Inc. and the directors and officers of Bio-Path Subsidiary became the directors and officers of Bio-Path Holdings, Inc. The Company’s operations to date have been limited to organizing and staffing the Company, acquiring, developing and securing its technology and undertaking product development for a limited number of product candidates.

In June 2015, the Company established an “at the market” (“ATM”) program through which it may offer and sell up to $25.0 million of its common stock from time to time, at Bio-Path’s discretion, through an investment banking firm, acting as sales agent. Sales of Bio-Path common stock under the ATM program will be made directly on or through The Nasdaq Capital Market, among other methods. The ATM program may be terminated by either the investment banking firm or the Company upon ten days’ notice. We are subject to certain restrictions on our ability to offer and sell shares of our common stock under the ATM program. To date, the Company has not offered or sold any shares of its common stock under the ATM program.

On September 20, 2018, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell an aggregate of 98,454 shares of our common stock and pre-funded warrants to purchase up to 14,624 shares of our common stock for gross proceeds of approximately $1.5 million under our effective shelf registration statement on Form S-3 (File No. 333-2152051) (the “2017 Shelf Registration Statement”), which became effective on January 9, 2017 (the “2018 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 113,077 shares of our common stock (the “2018 Private Placement”). Additionally, we issued warrants to purchase up to 6,785 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the 2018 Registered Direct Offering and the 2018 Private Placement. The 2018 Registered Direct Offering and the 2018 Private Placement closed on September 25, 2018. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.2 million.

On January 14, 2019, we entered into an underwriting agreement with H.C. Wainwright & Co., LLC relating to an underwritten public offering of 429,616 shares of our common stock for gross proceeds of approximately $1.1 million under the 2017 Shelf Registration Statement (the “2019 Underwritten Offering”). The offering price to the public in the 2019 Underwritten Offering was $2.60 per share, and H.C. Wainwright & Co., LLC agreed to purchase the shares in the 2019 Underwritten Offering from the Company pursuant to the underwriting agreement at a price of $2.418 per share. Additionally, we issued warrants to purchase up to 25,777 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as underwriter in connection with the 2019 Underwritten Offering. The 2019 Underwritten Offering closed on January 17, 2019. The net proceeds to the Company from the 2019 Underwritten Offering, after deducting the underwriting discounts and commissions and expenses and the Company’s estimated offering expenses, and excluding the proceeds, if any, from the exercise of the underwriter warrants, were approximately $0.9 million.

On January 17, 2019, we effected a reverse stock split of our outstanding shares of common stock at a ratio of 1-for-20, and our common stock began trading on the split-adjusted basis on the Nasdaq Capital Market at the commencement of trading on January 18, 2019. All common stock share and per share amounts in our consolidated financial statements have been adjusted to give effect to the 1-for-20 reverse stock split.

On January 18, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 648,233 shares of our common stock for gross proceeds of approximately $1.7 million under the 2017 Shelf Registration Statement (the “January 2019 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreement to issue to such investors Series A warrants to purchase up to 324,117 shares of our common stock (the “January 2019 Private Placement”). Additionally, we issued warrants to purchase up to 38,894 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the 2019 Registered Direct Offering and the 2019 Private Placement. The 2019 Registered Direct Offering and the 2019 Private Placement closed on January 23, 2019. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.5 million.

On March 12, 2019, we entered into a securities purchase agreement with certain investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 712,910 shares of our common stock for gross proceeds of approximately $18.5 million under the 2017 Shelf Registration Statement (the “March 2019 Registered Direct Offering”). Additionally, we issued warrants to purchase up to 42,775 shares of our common stock in a private placement to H.C. Wainwright & Co., LLC as compensation for its services as a placement agent in connection with the March 2019 Registered Direct Offering. The March 2019 Registered Direct Offering closed on March 14, 2019. The net proceeds to us from the offerings, after deducting the placement agent’s fees and expenses, our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $17.0 million.

As the Company has not begun its planned principal operations of commercializing a product candidate, the Company’s activities are subject to significant risks and uncertainties, including the potential requirement to secure additional funding, the outcome of the Company’s clinical trials, and failing to operationalize the Company’s current drug candidates before another company develops similar products.

Recent Accounting Pronouncements

2. Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability initially measured at the present value of the lease payments on the balance sheet for all leases with terms longer than 12 months. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In 2018, the FASB issued ASU 2018-01 and ASU 2018-11, which collectively adds two practical expedients and provides a second modified retrospective transition method in the year of adoption. Management adopted the new standard on January 1, 2019 using the modified retrospective transition approach with no restatement of prior periods or cumulative adjustment to accumulated deficit. We elected the “package of practiced expedients”, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and indirect costs. We also elected the short-term lease exemption and therefore do not recognize a ROU assets or corresponding liability for lease agreements with an original term of 12 months or less. Consequently, prior year financials statements have not been updated and the disclosures required under the new standard have not been provided for periods prior to the adoption date. Upon adoption of the new standards, the Company recognized $0.1 million for ROU assets and corresponding lease liabilities on the consolidated balance sheet related to leases for office and lab space. The adoption of these ASU’s on January 1, 2019 did not have a significant impact on our consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The new standard eliminates certain disclosure requirements for fair value measurements for all entities, requires public entities to disclose certain new information and modifies some disclosure requirements. This standard is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. Management is currently evaluating the impact of future adoption of the new standard on the Company’s consolidated financial statements.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606. The new standard provides guidance on how to assess whether certain transactions between collaborative arrangement participants should be accounted for within the revenue recognition standard. The update also provides more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. The new standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years with early adoption permitted. The Company early adopted this standard effective December 31, 2018 and notes that it did not a significant impact on our consolidated financial statements as the Company currently does not have significant collaborative agreements in place.

Management has reviewed all other recently issued pronouncements and has determined they will have no material impact on the Company’s consolidated financial statements.

8. Stock-Based Compensation Plan

The 2017 Plan – On December 21, 2017, the Company’s stockholders approved the Bio-Path Holdings, Inc. 2017 Stock Incentive Plan (the “2017 Plan”), which replaced the First Amended 2007 Stock Incentive Plan, as amended (the “2007 Plan”). The 2007 Plan expired by its terms in January 2018, and no awards were made under the 2007 Plan from the approval of the 2017 Plan on December 21, 2017 until the expiration of the 2007 Plan. The 2017 Plan provides for the grant of Incentive Stock Options, Non-Qualified Stock Options, Restricted Shares, Restricted Share Units, Stock Appreciation Rights, Performance-Based Awards and other stock-based awards, or any combination of the foregoing to the Company’s employees, non-employee directors and consultants. As of December 31, 2018, the total number of shares reserved and available for grant and issuance pursuant to the 2017 Plan was 60,000 shares, subject to the terms of the 2017 Plan. Under the 2017 Plan, the exercise price of awards is determined by the Board of Directors or the compensation committee of the Board of Directors, and for options intended to qualify as qualified Incentive Stock Options, may not be less than the fair market value as determined by the closing stock price at the date of the grant. Each option and award under the 2017 Plan shall vest and expire as determined by the Board of Directors or the compensation committee. Options expire no later than ten years from the date of grant. All grants provide for accelerated vesting if there is a change of control, as defined in the 2017 Plan.

Stock-based compensation expense for the three months ended March 31, 2019 and March 31, 2018 was $0.2 million and $0.1 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for both the three months ended March 31, 2019 and March 31, 2018 was $0.1 million. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended March 31, 2019 and March 31, 2018 was $25,000 and $20,000, respectively.

The Company utilized the Black-Scholes valuation model for estimating the fair value of the stock options granted, with the following weighted-average assumptions for options granted in the three months ended March 31, 2019 and 2018, respectively:

	2019			2018
Risk-free interest rate		2.23	%		2.59	%
Expected volatility		126	%		95	%
Expected term in years		6.0			6.1
Dividend yield		-%			-%

The following summary represents option activity under the Company’s stock-based compensation plans for the three months ended March 31, 2019:

				Weighted-
				Average
				Exercise
	Options			Price
	(in thousands)
Outstanding at December 31, 2018		37		$	112.60

Outstanding at March 31, 2019		71			67.26
Exercisable at March 31, 2019		16			186.16

As of March 31, 2019, the aggregate intrinsic value of outstanding stock options was $0.1 million. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on March 31, 2019 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2019. This amount changes based on the fair market value of the Company’s stock.

As of March 31, 2019, unamortized stock-based compensation expense for all outstanding options was $1.0 million, which is expected to be recognized over a weighted average vesting period of 2.4 years.

Leases [Abstract]

Leases

10. Leases

In April 2014, the Company entered into a five-year lease agreement for administrative office space located in Bellaire, Texas. The term of the lease began on August 1, 2014 and terminates on July 31, 2019.

In April 2016, the Company entered into a three-year lease agreement for lab space located in Bellaire, Texas. The term of lease began on May 1, 2016 and terminates on April 30, 2019 and requires Bio-Path to pay $2,500 per month over the term of the lease. In December 2018, we entered into an amendment to the agreement with the term of the extension beginning on May 1, 2019 and terminating on April 30, 2022 and will require Bio-Path to pay $2,575 per month over the term.

At the inception of an agreement, the Company determines if the agreement is a lease based on the unique facts and circumstances in each agreement. Lease classification, recognition, and measurement are then determined at the lease commencement date. For agreements that contain a lease, we identify lease and non-lease components, determine the consideration in the contract, determine whether the lease is an operating or financing lease and recognize ROU assets and lease liabilities. Lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable so we use an incremental borrowing rate based on the information available at the lease commencement date, which represents an estimated rate that would be incurred to borrow over a similar term in a similar economic environment. The incremental borrowing rate utilized on our lease liabilities as of March 31, 2019 was 8.0%.

Our current leases include options to renew which can impact the lease term. The exercise of these options is at the Company’s discretion and we do not include any of these options within the expected lease term as we are not reasonably certain we will exercise these options. Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis within our consolidated financial statements. Our leases are included in ROU assets, current portion of lease liabilities and noncurrent lease liabilities in our consolidated balance sheet as of March 31, 2019.

 The following table summarizes our operating lease assets and liabilities as of March 31, 2019:
