Notes to the Unaudited Condensed Consolidated Financial Statements

Unless the context requires otherwise, references in these Notes to the Condensed 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 unaudited condensed interim financial statements have been prepared in conformity with the authoritative U.S. generally accepted accounting principles (GAAP) for interim financial information and 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 required by GAAP for complete consolidated financial statements. 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, 2021. The results of operations for the period ended September 30, 2022, 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. The Company’s 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 lipid bilayer having neutral charge. The Company believes 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 125 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, the Company currently has four antisense drug candidates in development to treat at least five different cancer disease indications.

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. Effective December 31, 2014, the Company changed its 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.

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. 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.            Significant Accounting Policies

Net Loss Per Share – Basic net loss per common share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding during the period. Although there were warrants and stock options outstanding as of September 30, 2022 and 2021, no potential common shares are included in the computation of any diluted per share amount, as they would be antidilutive. Consequently, diluted net loss per share as presented in the condensed consolidated financial statements is equal to basic net loss per share for the three and nine months ended September 30, 2022 and 2021. The calculation of diluted earnings per share for 2022 did not include 657,408 shares and 400,531 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2022 as the effect would be antidilutive. The calculation of diluted earnings

9

per share for 2021 did not include 485,908 shares and 429,791 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2021 as the effect would be antidilutive.

Fair Value - The fair values of cash and cash equivalents, accounts payable and accrued liabilities approximate their carrying values because of the short-term maturities of these instruments.

3.            Prepaid Drug Product

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 recognized certain expenses and incurred installment costs for its contract drug manufacturing and raw material suppliers with prepayments totaling $0.5 million as of December 31, 2021 pursuant to drug supply contracts for the manufacture and delivery of prexigebersen for testing in a Phase 2 clinical trial and BP1002 for testing in a Phase 1 clinical trial. The Company recognized certain expenses and incurred additional installment costs during the first nine months of 2022, with advanced payments remaining to be expensed totaling $2.3 million as of September 30, 2022.

4.            Other Current Assets

The 2021 Public Offering closed on February 18, 2021. The net proceeds from the offerings, after deducting the placement agent’s fees and expenses and the Company’s offering expenses, were approximately $12.2 million.

At-The-Market Offering Agreement - On July 13, 2020, the Company entered into an At-The-Market Offering Agreement (the “Offering Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), as sales agent and/or principal, pursuant to which the

From July 14, 2020 to August 18, 2021, offers and any applicable sales of shares of common stock under the Offering Agreement were made pursuant to the base prospectus contained in the 2019 Shelf Registration Statement and a related prospectus supplement filed with the SEC on July 14, 2020, for an aggregate offering price of up to $7.0 million. From August 19, 2021 to June 14, 2022, offers and any applicable sales of shares of common stock under the Offering Agreement were made pursuant to the base prospectus contained in the 2019 Shelf Registration Statement and a related prospectus supplement filed with the SEC on August 19, 2021, as amended pursuant to an amendment to prospectus supplement filed with the SEC on March 15, 2022, for an aggregate offering price of up to $10.0 million. From and after June 15, 2022, offers and sales of shares of common stock under the Offering Agreement may be made pursuant to the Company’s shelf registration statement on Form S-3, which was declared effective by the SEC on June 14, 2022 (File No. 333-265282) (the “2022 Shelf Registration Statement”), and a related prospectus supplement filed with the SEC on June 14, 2022, as supplemented and amended pursuant to a prospectus supplement filed with the SEC on July 29, 2022, for an aggregate offering price of up to $3.0 million, provided that the Company may be limited in the amount of securities that it can currently sell under the Offering Agreement pursuant to Instruction I.B.6 to Form S-3 for so long as its public float remains less than $75.0 million. Under the Offering Agreement, Wainwright may sell shares by any method deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act of 1933, as amended. The Company will pay Wainwright a commission on the aggregate gross proceeds from each sale of shares under the Offering Agreement and has agreed to provide Wainwright with customary indemnification and contribution rights.

During the nine months ended September 30, 2022, the Company did not offer or sell any shares of its common stock under the Offering Agreement.

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 (as amended, 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. On December 19, 2019, the Company’s stockholders approved an amendment to the 2017 Plan to increase the number of shares reserved for grant and issuance pursuant to the 2017 Plan by 600,000 shares to 660,000 shares. 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 September 30, 2022 and 2021 was $0.2 million and $0.3 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for each of the three months ended September 30, 2022 and 2021 was $0.2 million. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended September 30, 2022 and 2021 was $49,000 and $46,000, respectively.

Stock-based compensation expense for each of the nine months ended September 30, 2022 and 2021 was $0.6 million. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for each of the nine months ended September 30, 2022 and 2021 was $0.5 million.

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 nine months ended September 30, 2022 and 2021, respectively:

	2022		2021
Risk-free interest rate	2.43	%	1.15	%
Expected volatility	127	%	128	%
Expected term in years	6.0		6.0
Dividend yield	—	%	—	%

The following summary represents option activity under the Company’s stock-based compensation plans for the nine months ended September 30, 2022:

		Weighted-
		Average
		Exercise
	Options	Price
	(in thousands)
Outstanding at December 31, 2021	486	$	14.58
Granted	192		3.71
Forfeited	(2)		7.02
Expired	(18)		5.96
Outstanding at September 30, 2022	658	$	11.67
Vested and expected to vest September 30, 2022	629	$	11.96
Exercisable at September 30, 2022	289	$	19.99

As of September 30, 2022, outstanding stock options did not have any aggregate intrinsic value. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on September 30, 2022 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 September 30, 2022. This amount changes based on the fair value of the Company’s stock.

As of September 30, 2022, unamortized stock-based compensation expense for all outstanding options was $1.5 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 – Total commitments for the Company’s drug supplier project plan were $5.0 million as of September 30, 2022, comprised of $2.4 million for manufacture of the Company’s Grb2 drug substance, $1.8 million for the manufacture of prexigebersen drug product, $0.6 million for manufacturing supply chain expansion and $0.2 million for testing services. The Company expects to incur $5.0 million of these commitments over the next 12 months.

10.         Subsequent Event 

2022 Registered Direct Offering and 2022 Private Placement – On November 6, 2022, the Company entered into a placement agency agreement with Roth Capital Partners, LLC relating to the 2022 Registered Direct Offering and the 2022 Private Placement (each as defined below). In addition, on November 6, 2022, the Company entered into securities purchase agreements with several institutional and accredited investors pursuant to which the Company agreed to sell, in a registered direct offering, an aggregate of 800,000 shares of its common stock for gross proceeds of approximately $2.0 million under the base prospectus contained in the 2022 Shelf Registration Statement and a related prospectus supplement filed with the SEC on November 9, 2022 (the “2022 Registered Direct Offering”). In a concurrent private placement, the Company also agreed pursuant to the securities purchase agreements to issue to such investors warrants to purchase up to 800,000 shares of its common stock (the “2022 Private Placement”). The 2022 Registered Direct Offering and the 2022 Private Placement closed on November 9, 2022. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses and the Company’s offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.7 million.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

When you read this Item of this Quarterly Report on Form 10-Q, it is important that you also read the unaudited financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and our audited financial statements and notes thereto included in our Annual Report on Form 10-K as of the fiscal year ended December 31, 2021. This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. We use words such as “anticipate,” “estimate,” “plan,” “project,” “continuing,” “ongoing,” “expect,” “believe,” “intend,” “may,” “will,” “should,” “could,” and similar expressions to identify forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements due to the impact, risks and uncertainties related to COVID-19 and actions taken by governmental authorities or others in connection therewith. To date, COVID-19’s impact on our operations has been limited to the inability to travel to clinical trial sites, clinical trial sites not allowing nonessential personnel on site for the purpose of monitoring activity and delays in the manufacture of our drug requirements by contracted third-party manufacturers. We anticipate COVID-19 may have an effect on patient recruiting in the near term as social distancing mandates are in effect. We believe these operational issues can be managed through remote monitoring capabilities currently being developed and deployed. Our actual results could also differ materially from those anticipated in these forward-looking statements for many other reasons, including the matters discussed in “Item 1A. Risk Factors” to Part I of our Annual Report on Form 10-K as of the fiscal year ended December 31, 2021, the matters discussed in “Item 1A. Risk Factors” to Part II of this Quarterly Report on Form 10-Q and other risks and uncertainties discussed in filings made with the SEC. See “Cautionary Note Regarding Forward-Looking Statements” in this Quarterly Report on Form 10-Q for additional discussion regarding risks associated with forward-looking statements.

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 lipid bilayer having neutral charge. 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 125 patients, our 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 four drug candidates in development to treat at least five different cancer disease indications. Our lead drug candidate, prexigebersen (pronounced prex” i je ber’ sen), which targets growth factor receptor-bound protein 2 (Grb2), initially started the efficacy portion of a Phase 2 clinical trial for untreated acute myeloid leukemia (“AML”) patients in combination with low-dose cytarabine (“LDAC”). The interim data released on March 6, 2019 showed that 11 (65%) of the 17 evaluable patients had a response, including five (29%) who achieved complete remission (“CR”), inclusive of one CR with incomplete hematologic recovery (“CRi”) and one morphologic leukemia-free state, and six (35%) stable disease responses, including two patients who had greater than a 50% reduction in bone marrow blasts. However, DNA hypomethylating agents are now the most frequently used agents in the treatment of elderly AML patients in the U.S. and Europe. As a result, Stage 2 of the Phase 2 trial in AML was amended to remove the combination treatment of prexigebersen and LDAC and replace it with the combination treatment of prexigebersen and decitabine, a DNA hypomethylating agent, for treatment of a second cohort of untreated AML patients. Since decitabine is also used as a treatment for relapsed/refractory AML patients, a cohort of relapsed/refractory AML patients was also added to the study.

The U.S. Food and Drug Administration (“FDA”) granted approval of venetoclax in combination with LDAC, decitabine or azacytidine (the latter two drugs are DNA hypomethylating agents) as frontline therapy for newly diagnosed AML in adults who are 75 years or older, or who have comorbidities precluding intensive induction chemotherapy. We believe this approval of the frontline venetoclax and decitabine combination therapy provides an opportunity for combining prexigebersen with the combination therapy for the treatment of de novo AML patients. Preclinical efficacy studies for the triple combination treatment of prexigebersen, decitabine and venetoclax in AML have been successfully completed. In the preclinical efficacy studies, four AML cancer cell lines were treated with three different combinations of decitabine, venetoclax and prexigebersen. Decrease in AML cell viability was the primary

13

measure of efficacy. The triple combination of decitabine, venetoclax and prexigebersen showed significant improvement in efficacy in three of the four AML cell lines. Based on these results, we believe that adding prexigebersen to the treatment combination of decitabine and venetoclax could lead to improved efficacy in AML patients. Accordingly, we further amended Stage 2 of this Phase 2 clinical trial to add the triple combination treatment comprised of prexigebersen, decitabine and venetoclax.

Our approved amended Stage 2 for this Phase 2 clinical trial currently has three cohorts of patients. The first two cohorts will treat patients with the triple combination of prexigebersen, decitabine and venetoclax. The first cohort will include untreated AML patients, and the second cohort will include relapsed/refractory AML patients. Finally, the third cohort will treat relapsed/refractory AML patients, who are venetoclax-resistant or -intolerant, with the two-drug combination of prexigebersen and decitabine. The full trial design plans have approximately 98 evaluable patients for the first cohort having untreated AML patients with a preliminary review performed after 19 evaluable patients and a formal interim analysis after 38 evaluable patients. The full trial design plans have approximately 54 evaluable patients for each of the second cohort, having relapsed/refractory AML patients, and the third cohort, having AML patients who are venetoclax-resistant or -intolerant, in each case with a review performed after 19 evaluable patients. The study is anticipated to be conducted at up to ten clinical sites in the U.S., and Gail J. Roboz, MD is the national coordinating Principal Investigator for the Phase 2 trial. Dr. Roboz is a professor of medicine and director of the Clinical and Translational Leukemia Program at the Weill Medical College of Cornell University (the “Weill Medical College”) and the New York-Presbyterian Hospital in New York City. On August 13, 2020, we announced the enrollment and dosing of the first patient in this approved amended Stage 2 of the Phase 2 clinical trial.

On April 5, 2021, we announced the successful completion of the safety run-in of Stage 2 of the Phase 2 clinical study. In the safety run-in of the triple combination, six evaluable patients were treated with the combination of prexigebersen, decitabine and venetoclax. These patients included four relapsed/refractory AML patients, and two newly diagnosed AML patients. In the preliminary safety data review, five of the patients (83%) responded to treatment, including four (67%) achieving CR and one (17%) achieving CRi. Recent publications provide that CR rates to combination treatment with decitabine and venetoclax (but without prexigebersen) are 42 to 52% for relapsed/refractory AML patients and 0 to 39% for relapsed/refractory secondary AML patients. Response rates to frontline treatment with decitabine and venetoclax (but without prexigebersen) are 62 to 71% for newly diagnosed AML patients. These preliminary data, presented at the 2021 American Society of Hematology Annual Meeting, showed the treatment was well-tolerated and there were no dose limiting toxicities attributed to prexigebersen. Three patients remained on treatment for more than one cycle.

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. On November 21, 2019, we announced that the FDA cleared an Investigational New Drug (“IND”) application for BP1002 for an initial Phase 1 clinical trial that will evaluate the ability of BP1002 to treat refractory/relapsed lymphoma and chronic lymphocytic leukemia patients. The Phase 1 clinical trial is being conducted at several leading cancer centers, including The University of Texas MD Anderson Cancer Center (“MD Anderson Cancer Center”) and the Georgia Cancer Center. On November 19, 2020, we announced the enrollment and dosing of the first patient in the Phase 1 clinical trial.

Additionally, preclinical studies suggest that the combination of BP1002 with decitabine is efficacious in venetoclax-resistant leukemia and lymphoma cells. An abstract of the preclinical study was presented at the 2021 American Association for Cancer Research (“AACR”) Annual Meeting. On August 24, 2021, we announced that the FDA cleared an IND application for BP1002 for an initial Phase 1/1b clinical trial that will evaluate the ability of BP1002 to treat refractory/relapsed AML patients. The Phase 1/1b clinical trial is anticipated to be conducted at several leading cancer centers in the United States, including the Weill Medical College, MD Anderson Cancer Center, Scripps Health and The University of California at Los Angeles Cancer Center. Gail J. Roboz, M.D., will serve as the national coordinating Principal Investigator for the Phase 1/1b trial. On October 24, 2022, we announced the enrollment and dosing of the first patient in the Phase 1/1b clinical trial.

Our third drug candidate, Liposomal STAT3 (“BP1003”), targets the STAT3 protein and is currently in IND enabling studies 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 cancer patient derived tumor model. An abstract of the preclinical study was presented at the 2019 AACR Annual Meeting. Our lead indication for BP1003 is pancreatic cancer due to the severity of this disease and the lack of effective, life-extending treatments. For example, pancreatic adenocarcinoma is projected to be the second most lethal cancer behind lung cancer by 2030. Typical survival for a metastatic pancreatic cancer patient is about three to six months from diagnosis. Additionally, an abstract

14

of the preclinical study demonstrating that BP1003 enhanced the sensitivity of breast and ovarian cancer cells to chemotherapy was presented at the 2022 AACR Annual Meeting. We successfully completed several IND enabling studies of BP1003 in 2021 and have one additional IND enabling study to complete. Once the additional study is successfully completed, our goal is to file an IND as soon as the first half of 2023. Based on the filing of the IND, we expect to initiate the first-in-humans Phase 1 study of BP1003 in patients with refractory, metastatic solid tumors, including pancreatic cancer and NSCLC.

In addition, a modified product named BP1001-A, our fourth drug candidate, has shown to enhance chemotherapy efficacy in preclinical solid tumor models. Results of the preclinical study were published in the scientific journal Oncotarget in July 2020. BP1001-A incorporates the same drug substance as prexigebersen but has a slightly modified formulation designed to enhance nanoparticle properties. In late 2019, we filed an IND application to initiate a Phase 1/1b clinical trial of BP1001-A in patients with solid tumors, including ovarian, endometrial, pancreatic and breast cancer. Ovarian cancer is one of the most common types of gynecologic malignancies, with approximately 50% of all cases occurring in women older than 63 years. On October 27, 2021, we announced that the FDA cleared the IND application for BP1001-A for the initial Phase 1/1b clinical trial, which allows us to proceed with next steps to open the clinical trial.

Our DNAbilize® technology-based products are available for out-licensing or partnering. We intend to apply our drug technology template to new disease-causing protein targets 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 our drug development programs, 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.

We have certain intellectual property as the basis for our current drug products in clinical development, prexigebersen, BP1002, BP1003 and BP1001-A. 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.

As of September 30, 2022, we had an accumulated deficit of $87.6 million. Our net loss was $3.5 million and $2.1 million for the three months ended September 30, 2022 and 2021, respectively. Our net loss was $9.9 million and $6.3 million for the nine months ended September 30, 2022 and 2021, 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.

Recent Accounting Pronouncements

There are no recent accounting pronouncements that have a material impact on our 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. 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.

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 tests of our drug candidates that we may initiate;

● competing technological and market developments;

● the performance of third-party manufacturers and suppliers;

16

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

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

● the impact, risks and uncertainties related to COVID-19 and actions taken by governmental authorities or others in connection therewith.

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.

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

18

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 $13.7 million as of September 30, 2022, a decrease of $10.1 million compared to December 31, 2021. We believe that our available cash at September 30, 2022, together with the net proceeds received from the 2022 Registered Direct Offering and the 2022 Private Placement, as described below, 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 nine months ended September 30, 2022 was $10.1 million. Excluding non-cash stock-based compensation expense of $0.6 and depreciation and amortization expenses of $0.1 million included in net loss, net cash used in operating activities for the nine months ended September 30, 2022 consisted primarily of the net loss for the period of $9.9 million and an increase in operating assets of $2.1 million which was partially offset by an increase in accounts payable and accrued expenses of $1.2 million. Net cash used in operating activities for the nine months ended September 30, 2021 was $7.1 million. Excluding non-cash stock-based compensation expense of $0.6 million and depreciation and amortization expenses of $0.1 million included in net loss, net cash used in operating activities for the nine months ended September 30, 2021 consisted primarily of the net loss for the period of $6.3 million, an increase in current assets of $1.4 million and a decrease in operating liabilities of $0.1 million.

Investing Activities. Net cash used in investing activities for the nine months ended September 30, 2022 consisted of a capital expenditure totaling $21,000 which was related to a research and development equipment purchase. Net cash used in investing activities for the nine months ended September 30, 2021 consisted of capital expenditures totaling $47,000 which were related to research and development equipment purchases.

Financing Activities. There were no financing activities for the nine months ended September 30, 2022. Net cash provided by financing activities for the nine months ended September 30, 2021 was $20.0 million. Net cash provided by financing activities for the nine months ended September 30, 2021 consisted primarily of net proceeds of $12.2 million from the 2021 Public Offering (as defined below) and net proceeds of $3.7 million from sales of our common stock under the Offering Agreement (as defined below), each as described below, as well as net proceeds of $4.2 million from the exercise of warrants to purchase shares of our common stock.

2021 Public Offering

On February 16, 2021, we entered into a placement agency agreement with Roth Capital Partners, LLC relating to a public offering of 1,710,600 shares of our common stock for gross proceeds of approximately $13.0 million under the 2019 Shelf Registration Statement (as defined below) (the “2021 Public Offering”). In addition, on February 16, 2021, we entered into a securities purchase agreement with certain institutional investors pursuant to which we agreed to sell an aggregate of 1,650,000 shares of our common stock in the 2021 Public Offering to such investors. The 2021 Public Offering closed on February 18, 2021. The net proceeds from the 2021 Public Offering, after deducting the placement agent’s fees and expenses and our offering expenses, were approximately $12.2 million.

2022 Shelf Registration Statement

On May 27, 2022, we filed a shelf registration statement on Form S-3 with the SEC, which was declared effective by the SEC on June 14, 2022 (File No. 333-265282) (the “2022 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 June 5, 2019 (File No. 333-231537) (the “2019 Shelf Registration Statement”), was deemed terminated pursuant to Rule 415(a)(6) under the Securities Act. The 2022 Shelf Registration Statement was filed to register the offering, issuance and sale of (i) up to $110.0 million of our common stock, preferred stock, warrants to purchase common stock or preferred stock or any combination thereof, either individually or in units, (ii) up to $9.0 million of our common stock under the Offering Agreement (as defined below), which $9.0 million was subsequently reduced to $3.0 million pursuant to a prospectus supplement filed with the SEC on July 29, 2022, and (iii) up to 237,890 shares of our common stock pursuant to the exercise of warrants outstanding on May 27,

19

2022. The $3.0 million of our common stock that may be offered, issued and sold under the Offering Agreement is included in the $110.0 million of our securities that may be offered, issued and sold. Upon termination of the Offering Agreement, any portion of the $3.0 million of our common stock that is not sold pursuant to the Offering Agreement will be available for sale in other offerings pursuant to the 2022 Shelf Registration Statement. Because our public float is less than $75.0 million, our ability to offer and sell any securities under the 2022 Shelf Registration Statement is currently limited pursuant to Instruction I.B.6 to Form S-3. For so long as our public float is less than $75.0 million, the aggregate market value of securities we sell pursuant to Instruction I.B.6 to Form S-3 during any 12 consecutive months may not exceed one-third of our public float. 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.

At-The-Market Offering Agreement

On July 13, 2020, we entered into an At-The-Market Offering Agreement (the “Offering Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), as sales agent and/or principal, pursuant to which we may offer and sell, from time to time, through or to Wainwright, shares of our common stock. From July 14, 2020 to August 18, 2021, offers and any applicable sales of shares of common stock under the Offering Agreement were made pursuant to the base prospectus contained in the 2019 Shelf Registration Statement and a related prospectus supplement filed with the SEC on July 14, 2020, for an aggregate offering price of up to $7.0 million. From August 19, 2021 to June 14, 2022, offers and any applicable sales of shares of common stock under the Offering Agreement were made pursuant to the base prospectus contained in the 2019 Shelf Registration Statement and a related prospectus supplement filed with the SEC on August 19, 2021, as amended pursuant to an amendment to prospectus supplement filed with the SEC on March 15, 2022, for an aggregate offering price of up to $10.0 million. From and after June 15, 2022, offers and sales of shares of common stock under the Offering Agreement may be made pursuant to the 2022 Shelf Registration Statement and a related prospectus filed with the SEC on June 14, 2022, as supplemented and amended pursuant to a prospectus supplement filed with the SEC on July 29, 2022 (as supplemented and amended, the “ATM Prospectus”), for an aggregate offering price of up to $3.0 million, provided that we may be limited in the amount of securities that we can currently sell under the Offering Agreement pursuant to Instruction I.B.6 to Form S-3 for so long as our public float remains less than $75.0 million. Under the Offering Agreement, Wainwright 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 Wainwright a commission on the aggregate gross proceeds from each sale of shares under the Offering Agreement and have agreed to provide Wainwright with customary indemnification and contribution rights. We have also agreed to reimburse Wainwright for certain specified expenses. During the three months ended September 30, 2022, we did not offer or sell any shares of our common stock under the Offering Agreement. As of September 30, 2022, we had sold 1,328,800 shares of our common stock under the Offering Agreement for gross proceeds of approximately $8.4 million; all of such sales were made pursuant to the 2019 Shelf Registration Statement and related prospectuses and prospectus supplements, and up to $3.0 million of shares of our common stock remains available for offer and sale under the Offering Agreement pursuant to the 2022 Shelf Registration Statement and the ATM Prospectus. The net proceeds from the offering, after deducting commissions and our offering expenses, were approximately $8.0 million.

2022 Registered Direct Offering and 2022 Private Placement

On November 6, 2022, we entered into a placement agency agreement with Roth Capital Partners, LLC relating to the 2022 Registered Direct Offering and the 2022 Private Placement. In addition, on November 6, 2022, we entered into securities purchase agreements with several institutional and accredited investors pursuant to which we agreed to sell, in a registered direct offering, an aggregate of 800,000 shares of our common stock for gross proceeds of approximately $2.0 million under the base prospectus contained in the 2022 Shelf Registration Statement and a related prospectus supplement filed with the SEC on November 9, 2022 (the “2022 Registered Direct Offering”). In a concurrent private placement, we also agreed pursuant to the securities purchase agreements to issue to such investors warrants to purchase up to 800,000 shares of our common stock (the “2022 Private Placement”). The 2022 Registered Direct Offering and the 2022 Private Placement closed on November 9, 2022. The net proceeds to the Company from the offerings, after deducting the placement agent’s fees and expenses and our offering expenses, and excluding the proceeds, if any, from the exercise of the warrants issued in the offerings, were approximately $1.7 million.

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, BP1003 and BP1001-A.

20

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, 2021. For more information, see Note 1 to the Unaudited Condensed Consolidated Financial Statements included herein.

Off-Balance Sheet Arrangements

As of September 30, 2022, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles in the United States has required our management 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. 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, 2021.

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, 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 effective 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.

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. The Company’s 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 lipid bilayer having neutral charge. The Company believes 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 125 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, the Company currently has four antisense drug candidates in development to treat at least five different cancer disease indications.

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. Effective December 31, 2014, the Company changed its 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.

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. 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.

Net Loss Per Share – Basic net loss per common share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding during the period. Although there were warrants and stock options outstanding as of September 30, 2022 and 2021, no potential common shares are included in the computation of any diluted per share amount, as they would be antidilutive. Consequently, diluted net loss per share as presented in the condensed consolidated financial statements is equal to basic net loss per share for the three and nine months ended September 30, 2022 and 2021. The calculation of diluted earnings per share for 2022 did not include 657,408 shares and 400,531 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2022 as the effect would be antidilutive. The calculation of diluted earnings

per share for 2021 did not include 485,908 shares and 429,791 shares issuable pursuant to the exercise of outstanding common stock options and warrants, respectively, as of September 30, 2021 as the effect would be antidilutive.

The 2017 Plan – On December 21, 2017, the Company’s stockholders approved the Bio-Path Holdings, Inc. 2017 Stock Incentive Plan (as amended, 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. On December 19, 2019, the Company’s stockholders approved an amendment to the 2017 Plan to increase the number of shares reserved for grant and issuance pursuant to the 2017 Plan by 600,000 shares to 660,000 shares. 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 September 30, 2022 and 2021 was $0.2 million and $0.3 million, respectively. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for each of the three months ended September 30, 2022 and 2021 was $0.2 million. Stock-based compensation expense for personnel involved in the Company’s research and development activities for the three months ended September 30, 2022 and 2021 was $49,000 and $46,000, respectively.

Stock-based compensation expense for each of the nine months ended September 30, 2022 and 2021 was $0.6 million. Of these amounts, stock-based compensation expense for personnel involved in the Company’s general and administrative activities for each of the nine months ended September 30, 2022 and 2021 was $0.5 million. Stock-based compensation expense for personnel involved in the Company’s research and development activities for each of the nine months ended September 30, 2022 and 2021 was $0.1 million.

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 nine months ended September 30, 2022 and 2021, respectively:

	2022		2021
Risk-free interest rate	2.43	%	1.15	%
Expected volatility	127	%	128	%
Expected term in years	6.0		6.0
Dividend yield	—	%	—	%

The following summary represents option activity under the Company’s stock-based compensation plans for the nine months ended September 30, 2022:

		Weighted-
		Average
		Exercise
	Options	Price
	(in thousands)
Outstanding at December 31, 2021	486	$	14.58

Vested and expected to vest September 30, 2022	629	$	11.96
Exercisable at September 30, 2022	289	$	19.99

As of September 30, 2022, outstanding stock options did not have any aggregate intrinsic value. The aggregate intrinsic value represents the total pretax intrinsic value (the difference between the Company’s closing stock price on September 30, 2022 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 September 30, 2022. This amount changes based on the fair value of the Company’s stock.

As of September 30, 2022, unamortized stock-based compensation expense for all outstanding options was $1.5 million, which is expected to be recognized over a weighted average vesting period of 2.4 years.
