PDS BIOTECHNOLOGY CORPORATION AND SUBSIDIARY
Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 Nature of Operations


PDS Biotechnology Corporation, a Delaware corporation including its subsidiary collectively (the “Company” or “PDS Biotech”), is a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on the Company’s proprietaryits Versamune®, Versamune® plus our IL12 fused antibody-drug conjugate (ADC) PDS01ADC (formerly PDS0301/M9241) and Infectimune™Infectimune® T cell activating technology platforms.cell-activating platforms and PDS01ADC tumor targeting immunocytokine. The Company’s Versamune based productsCompany believes its targeted immunotherapies have demonstrated the potential to overcome the limitations of current immunotherapiesimmunotherapy approaches through the activation of the right type, quantity and potency of T cells. Versamune, and Versamune plus PDS01ADC is for treatments in oncology and Infectimune, for treatments in infectious disease. When paired with an antigen, which is a disease-related protein that is recognizable by inducing, the immune system, Versamune and Infectimune have both been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD4+CD4 helper and CD8+CD8 killer T cells, a specific sub-type of T cell that is more effective at killing infected or target cells. Infectimune is also designed to promote the induction of disease-specific neutralizing antibodies. PDS01ADC is an investigational tumor targeting IL-12 that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment. Versamune plus PDS01ADC enhances the proliferation, potency and longevity of antigen specific multifunctional CD8 T cells in the tumor microenvironment and works synergistically to overcome tumor immune suppression.


The Company’s immuno-oncology clinical candidates are of potential interest for use as a component of combination clinical candidates (for example, in combination with other leading technologies such as immune checkpoint inhibitors) to provide more effective treatments across a range of advanced cancers. The Company has developed multiple therapies, based on combinations of Versamune and disease-specific antigens, designed to train the immune system to recognize diseased cells and effectively attack and destroy them. The Company continues to advance its pipeline ofis also evaluating our immunotherapies as monotherapies in early-stage disease.  PDS Biotech is developing targeted clinical candidates to address a wide range oftreat several cancers including HPV-positiveHuman Papillomavirus (HPV)-positive cancers, (anal, cervical, headmelanoma, colorectal, lung, breast and neck, penile, vaginal, vulvar) and breast, colon, lung, prostate and ovarian cancers. The Company’s Infectimune -based vaccines have demonstrated the potential to induce, not only robust and durable neutralizing antibody response, but also powerful T cell responses including long-lasting memory T cell responses. The Company’s infectious disease candidates are of potential interest for use in COVID-19 and universal influenza vaccines.



From the Company’s inception, it has devoted substantially all of its efforts to drug development, business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital.


In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020, the World Health Organization (WHO) declared COVID-19 a public health emergency. The full impact of the COVID-19 pandemic continues to evolve. The COVID-19 pandemic has and could continue to negatively affect the Company’s liquidity and operations.  The FDA issued and since updated guidance to assist sponsors in assuring the safety of trial participants, maintaining compliance with Good Clinical Practice (GCP) and minimizing risks to trial integrity.  Clinical trial sites have implemented institution-specific measures securing the safety of patients and staff to ensure the integrity of the trials in the face of the ongoing pandemic. COVID-19 related travel and other restrictions may also impact the potential for on-site monitoring visiting and audits and inspections of Company personnel, third parties, and regulators. There may be shortages of site personnel and equipment necessary for the timely completion of clinical trials. PDS Biotech is providing support to address these challenges, but these mitigation measures may not overcome the obstacles that the pandemic has wrought which continue to impede progress of clinical trials.



Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on the Company’s future results, management believes the current cash reserves, leave the Company well-positioned to manage the business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain.

Note 2 – Summary of Significant Accounting Policies

(A)Unaudited interim financial statements:



The interim balance sheet at September 30, 2022,2023, the statements of operations and comprehensive loss and changes in stockholders’ equity and cash flows for the three and nine months ended September 30, 20222023 and 20212022 are unaudited. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP, in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair statement of its financial information. The results of operations for the three and nine months ended September 30, 20222023 are not necessarily indicative of the results to be expected for the year ending December 31, 20222023 or for any other future annual or interim period. The balance sheet as of December 31, 20212022 included herein was derived from the audited consolidated financial statements as of that date. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2021,2022, filed by the Company with the SEC in its Annual Report on Form 10-K on March 31, 2022.28, 2023.


(B)Use of estimates:


The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates. The most significant estimate relates to the fair value of securities underlying stock-based compensation.

(C)Significant risks and uncertainties:


The Company’s operations are subject to a number of factors that may affect its operating results and financial condition. Such factors include, but are not limited to: the clinical and regulatory development of its products,clinical candidates, the Company’s ability to preserve its cash resources, the Company’s review of strategic alternatives, the Company’s ability to add productclinical candidates to its pipeline, the Company’s intellectual property, the ability to efficiently and effectively conduct its clinical trials, competition from products manufactured and sold or being developed by other companies, the price of, and demand for, Company products if approved for sale, the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products, the Company’s ability to raise capital, and the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the COVID-19 pandemic and its variants.
diseases.


The Company currently has no commercially approved products. As such, there can be no assurance that the Company’s future research and development programs will be successfully commercialized. Developing and commercializing a product requires significant time and capital and is subject to regulatory review and approval as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting its intellectual property.

(D)Cash equivalents and concentration of cash balance:


The Company considers all highly liquid securities with a maturity weighted average of less than three months to be cash equivalents. The Company’s cash and cash equivalents in bank deposit accounts, at times, may exceed federally insured limits.

(E)Research and development:


Costs incurred in connection with research and development activities are expensed as incurred. These costs include licensing fees to use certain technology in the Company’s research and development projects as well as fees paid to consultants and entities that perform certain research and testing on behalf of the Company.


Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data, such as patient enrollment, clinical trial site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred.

(F)Patent costs:


The Company expenses patent costs as incurred and classifies such costs as general and administrative expenses in the accompanying statements of operations and comprehensive loss.

(G)Stock-based compensation:


The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, directors and non-employees to be recognized as expense in the consolidated statements of operations and comprehensive loss based on their grant date fair values. In order to determine the fair value of stock options on the date of grant, the Company uses the Black-Scholes option-pricing model. Inherent in this model are assumptions related to expected stock-price volatility, option term, risk-free interest rate and dividend yield. While the risk-free interest rate and dividend yield are less subjective assumptions that are based on factual data derived from public sources, the expected stock-price volatility and option term assumptions require a greater level of judgment. The Company expenses the fair value of its stock-based compensation awards to employees and directors on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes forfeitures as they occur.

8

(H)Net loss per common share:


Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted average common shares outstanding during the period. For all periods presented, the common shares underlying the stock options and warrants have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted average shares outstanding used to calculate both basic and diluted loss per common share is the same.


The potentially dilutive securities excluded from the determination of diluted loss per share as their effect is antidilutive, are as follows:

Total  5,890,131   4,877,075 

(I)Income taxes:


The Company provides for deferred income taxes under the asset and liability method, which requires deferred tax assets and liabilities to be recognized for the future tax consequences attributable to net operating loss carryforwards and for differences between the financial statement carrying amounts and the respective tax bases of assets and liabilities. Deferred tax assets are reduced if necessary, by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

(J)Fair value of financial instruments:



ASC 820, Fair Value Measurement, specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect market assumptions. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement).


The three levels of the fair value hierarchy are as follows:


Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 primarily consists of financial instruments whose value is based on quoted market prices such as exchange-traded instruments and listed equities.


Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly (e.g., quoted prices of similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active). Level 2 includes financial instruments that are valued using models or other valuation methodologies.


Level 3 — Unobservable inputs for the asset or liability. Financial instruments are considered Level 3 when their fair values are determined using pricing models, discounted cash flows or similar techniques and at least one significant model assumption or input is unobservable.

(K)Leases:



The Company determines if an arrangement is a lease at inception and recognizes the lease in accordance with ASC 842, Leases (“ASC 842”). Both financing and operating leases are included in right-of-use (“ROU”) assets, lease obligation-short term and lease obligation-long term in the Company’s consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. The Company determines the portion of the lease liability that is current as the difference between the calculated lease liability at the end of the current period and the lease liability that is projected 12 months from the current period.

Loan E and Loan F arewere uncommitted Loans that may becould have been advanced by the lenders upon their discretionthe parties agreement prior to July 31, 2023 upon the satisfaction of certain conditions. At this time the option to advance Loan E and Loan F has expired and Loan E and Loan F are no longer available to the Company under the Loan and Security Agreement. The Company may only use the proceeds of the Loans for working capital or general corporate purposes. Each Loan matures on the 48-month anniversary following the applicable funding date unless accelerated pursuant to certain events of default. Payments on the principal balance begin on October 1, 2024 and are paid monthly in the succeeding 24 months. The principal balance of each Loan bears a floating interest. The interest rate is calculated initially and, thereafter, each calendar month as the sum of (a) the per annum rate of interest from time to time published in The Wall Street Journal as contemplated by the Loan and Security Agreement, or any successor publication thereto, as the “prime rate” then in effect, plus (b) 5.75%; provided that, in the event such rate of interest is less than 4.00%, such rate shall be deemed to be 4.00% for purposes of calculating the interest rate. Interest is payable on a monthly basis based on each Loan principal amount outstanding the preceding month.  The Company, at its option upon at least ten (10) business days’ written notice to the lenders, may prepay all (and not less than all) of the outstanding Loan by simultaneously paying to each lender an amount equal to (i) any accrued and unpaid interest on the outstanding principal balance of the Loans; plus (ii) an amount equal to (A) if such Loan is prepaid on or before the Loan Amortization Date (as defined in the Loan and Security Agreement) applicable to such Loan, 3% of the then outstanding principal balance of such Loan, (B) if such Loan is prepaid after the Loan Amortization Date applicable to such Loan, but on or before the date that is 12 months after such Loan Amortization Date, 2% of the then outstanding principal balance of such Loan, or (C) if such Loan is prepaid more than 12 months after the Loan Amortization Date but prior to the stated maturity date applicable to such Loan, 1% of the then outstanding principal balance of such Loan; plus (iii) the outstanding principal balance of such Loan; plus (iv) all other sums, if any, that shall have become due and payable thereunder.  No prepayment premium will be applied to any outstanding balance of any Loan paid on the stated maturity date.


The Loan and Security Agreement contains customary representations, warranties and covenants, including covenants by the Company limiting additional indebtedness, liens, including on intellectual property, guaranties, mergers and consolidations, substantial asset sales, investments and loans, certain corporate changes, transactions with affiliates, and fundamental changes.

Going Concern


The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the filing of this Quarterly Report on Form 10-Q.  10-Q in accordance with ASC 205-40. Since inception, the Company has experienced net losses and negative cash flows from operations each fiscal year. The Company has no revenues and expects to continue to incur operating losses for the foreseeable future and may never become profitable.


The Company’s budgeted cash requirements in 20222023 and beyond include expenses related to continuing development and clinical studies.  Based on its available cash resources and cash flow projections as of the date the consolidated financial statements were available for issuance, management believes there are sufficient funds to continue operations and research and development programs for at least one year after the date of this Quarterly Report on Form 10-Q.

The Company plans to continue to fundexecute its operationsoperating plan by obtaining additional capital, principally through entering into collaborations, strategic alliances, or license agreements with third parties and/or additional public or private debt and capital funding needs through equity and/or debt financings.financing. However, the Company cannot be certainthere is no assurance that additional capital and/or financing will be available when needed or that,to the Company, and even if available, financingwhether it will be obtained on terms favorableacceptable to the Company or its existing stockholders.shareholders or in the amounts required. The Company may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to the Company’s stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict its operations. If the Company is unable to raise additional capitalunsuccessful in securing sufficient amounts or on acceptable terms, wefinancing, it may be requiredneed to delay, limit, reduce, or terminateeliminate its productresearch and development or future commercialization efforts orprograms, which could adversely affect its business prospects, grant rights to third parties to develop and market immunotherapies that the Company would otherwise prefer to develop and market itself.itself or cease operations. Any of these actions could harm its business, results of operations and prospects. Failure to obtain adequate financing also may adversely affect the Company’s ability to operate as a going concern.


As a result of these uncertainties, and as its plans are outside of management’s control, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for a period of at least 12 months from the date of the issuance of these unaudited condensed consolidated financial statements. The unaudited condensed consolidated financial statements do not include any adjustments to the carrying amounts and classifications of assets and liabilities that would result if the Company was unable to continue as a going concern.

Note 7 – Stock-Based Compensation


The Company has three equity compensation plans: the 2009 Stock Option Plan, 2014 Equity Incentive Plan and the 2018 Stock Incentive Plan (the “Plans”).


In 2014, the Company’s stockholders approved the 2014 Equity Incentive Plan pursuant to which the Company may grant up to 91,367 shares as ISOs, NQs and restricted stock units (“RSUs”), subject to increases as hereafter described (the “Plan Limit”). In addition, on January 1, 2015 and each January 1 thereafter and prior to the termination of the 2014 Equity Incentive Plan, pursuant to the terms of the 2014 Equity Incentive Plan, the Plan Limit was and shall be increased by the lesser of (x) 4% of the number of shares of Common Stock outstanding as of the immediately preceding December 31 and (y) such lesser number as the Board of Directors may determine in its discretion. In March 2019, the Plan was amended and restated which removed the annual increase component and was limited to 826,292 shares.



As previously disclosed, on December 8, 2020, the Board of Directors of the Company adopted, subject to stockholder approval, the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Inventive Plan (the “Restated Plan”), which would amendamended and restaterestated the Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Current Plan”). At the annual meeting of stockholders on June 17, 2021 the stockholders voted to approve the Restated Plan at the Annual Meeting. The Restated Plan is identical to the Current Plan in all material respects, except as follows: (a) the number of shares of Common Stock authorized for issuance under the Restated Plan will increase from 826,292 shares to 3,339,243 shares, plus the total number of shares that remained available for issuance, that are not covered by outstanding awards issued under the Current Plan, immediately prior to December 8, 2020; and (b) the Restated Plan will terminate on December 7, 2030, unless earlier terminated. On July 14, 2023, the Company’s stockholders approved an amendment to the Current Plan increasing the number of shares of common stock for issuance from 4,165,535 to 6,565,535 shares. As of September 30, 2022,2023, there were 1,303,113119,013 shares available for grant under the Restated Plan.


In 2018, the Company’s stockholders approved the 2018 Stock Incentive Plan pursuant to which the Company may grant up to 558,071 shares as (i) Stock Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock, (iv) Preferred Stock, (v) Stock Reload Options and/or (vi) Other Stock-Based Awards. As of September 30, 2023, there were 190,799 shares available for grant under the Restated Plan.


 Pursuant to the terms of the Plans, ISOs have a term of ten years from the date of grant or such shorter term as may be provided in the option agreement. Unless specified otherwise in an individual option agreement, ISOs generally vest over a four-year period. Unless terminated by the Board, the Plans shall continue to remain effective for a term of ten years or until such time as no further awards may be granted and all awards granted under the Plans are no longer outstanding.


 On June 17, 2019, the Board adopted the 2019 Inducement Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of non-qualified stock options. The Inducement Plan was recommended for approval by the Compensation Committee of the Board and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules.

On December 8, 2020, the Company amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 200,000 shares to 500,000 shares. On May 17, 2022, the Company further amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 500,000 shares to 1,100,000 shares. The 2019 Inducement Plan is administered by the Compensation Committee of the Board. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, non-qualified stock options under the 2019 Inducement Plan may only be made to an employee who has not previously been an employee or member of the Board (or any parent or subsidiary of the Company), or following a bona fide period of non-employment by the Company (or a parent or subsidiary of the Company), if he or she is granted such non-qualified stock options in connection with his or her commencement of employment with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary. As of September 30, 2022,2023, there were 285,215185,315 shares available for grant under the 2019 Inducement Plan.

Note 8 – Income Taxes


In assessing the realizability of the net deferred tax assets, the Company considers all relevant positive and negative evidence to determine whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The realization of the gross deferred tax assets is dependent on several factors, including the generation of sufficient taxable income prior to the expiration of the net operating loss carryforwards. The Company expects to have a loss for 20222023 and there will be no current income tax expense.  Additionally, there was a full valuation allowance against the net deferred tax assets as of September 30, 20222023 and December 31, 2021.2022. As such, the Company recorded no income tax benefit due to realization uncertainties.


The Company’s U.S. statutory rate is 21%. The primary factor impacting the effective tax rate for the three and nine months ended September 30, 20222023 is the anticipated full year operating loss which will require full valuation allowances against any associated net deferred tax assets.


Entities are also required to evaluate, measure, recognize and disclose any uncertain income tax provisionspositions taken on their income tax returns. The Company has analyzed its tax positions and has concluded that as of September 30, 2022,2023, there were no uncertain positions. The Company’s U.S. federal and state net operating losses have occurred since its inception and as such, tax years subject to potential tax examination could apply from that date because the utilization of net operating losses from prior years opens the relevant year to audit by the IRS and/or state taxing authorities.  The Company did not have any unrecognized tax benefits and has not accrued any interest or penalties for the three and nine months ended September 30, 20222023 and for the year ended December 31, 2021.2022.


In accordance with the State of New Jersey’s Technology Business Tax Certificate Program, which allows certain high technology and biotechnology companies to sell unused NOL carryforwards to other New Jersey-based corporate taxpayers, the Company sold New Jersey NOL carryforwards, resulting in the recognition of $1.2$1.4 million and $4.5$1.2 million of income tax benefit, net of transaction costs in the nine months ended September 30, 20222023 and 2021,2022, respectively.


Note 9 – Commitments and Contingencies

Employment Matters


The Company has entered into employment agreements with each of its executive officers. The employment agreements generally provide for, among other things, salary, bonus and severance payments. The employment agreements generally provide for between 12 months and 24 months of severance benefits to be paid to an executive (as well as certain potential bonus, COBRA and equity award benefits), subject to the effectiveness of a general release of claims, if the executive terminates his or her employment for good reason or if the Company terminates the executive’s employment without cause.  Such severance payments may be provided 90 days prior to and for as long as 24 months following the effective date of a change in control.  The continued provision of severance benefits is conditioned on each executive’s compliance with the terms of the Company’s confidentiality and invention and assignment agreement as well as his or her release of claims.

Rent


For month-to-month arrangements not impacted by the adoption of ASC 842, rent for the three and nine months ended September 30, 20222023 was $55,500$106,171 and $166,500$359,373 respectively, compared to the three and nine months ended September 202130, 2022 of $52,000$55,500 and $130,493.$165,500.

Exclusive License Agreement

In January 2023, we entered into an exclusive global license agreement with Merck KGaA, Darmstadt, Germany for the tumor targeting IL 12 fused antibody drug conjugate, M9241 (the “Merck KGaA License Agreement”). Pursuant to the Merck KGaA License Agreement, the Company agreed to make (i) development and first commercial sale milestone payments totaling up to $11 million upon the achievement of certain milestones, including the dosing of the fifth patient in a Phase 3 trial of the clinical candidate and first commercial sale of the product for a first and second indication in a major market, and (ii) up to $105 million upon achieving certain aggregate sales levels of the product.


The Company also agreed to pay Merck KGaA, Darmstadt, Germany a royalty of 10% on aggregate net sales of product as specified in the Merck KGaA License Agreement on a product-by-product and country-by-country basis until the later of: (i) ten years after the first commercial sale of a product in a given country; and (ii) the expiration or invalidation of the licensed patents covering the compound or product in such country. The royalty rate is subject to reduction in that event that a product is not covered by a valid patent claim, a biosimilar to the compound or the product comes on the market in a particular country, or if the Company obtains a license to any intellectual property owned or controlled by a third-party, but for which such license would be infringed by making, using or selling the compound.


Legal Proceedings


On or about December 27, 2021, Seth Van Voorhees,The Company is currently not a party to, and the former Chief Financial OfficerCompany’s property is not currently the subject of, the Company, filed a Demand for Arbitration against the Company with the American Arbitration Association, asserting that he was wrongfully terminated. In his demand, Dr. Van Voorhees contends that his alleged damages are expected to be no less than $3,000,000, plus interest, arbitration costs, attorneys’ fees and punitive damages. In July 2022, the Company and Dr. Van Voorhees entered into a confidential settlement agreement which includes the customary dismissal of action, full release of claims with no admission of liability. There were no any material changes to the Company’s accrued liabilities in connection with this matter.


While there can be no assurances as to the ultimate outcome of any pending legal proceeding or other loss contingency involving the Company, management does not believe any pending matter will be resolved in a manner that would have a material adverse effect on its financial position, results of operations or cash flows.proceedings. The Company may be involved, from time to time, in additional legal proceedings and claims arising in the ordinary course of its business. Such matters are subject to many uncertainties and outcomes are not predictable with assurance.

Company Overview

We are a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on our proprietary Versamune®, Versamune® plus IL12 fused anti-body drug conjugate (ADC) PDS01ADC (formerly PDS0301/M9241) and Infectimune™Infectimune® T cell activating technology platforms. Our Versamune based productscell-activating platforms and PDS01ADC tumor targeting immunocytokine. We believe our targeted immunotherapies have demonstrated the potential to overcome the limitations of current immunotherapiesimmunotherapy approaches through the activation of the right type, quantity and potency of T cells.  Versamune, and Versamune plus PDS01ADC are utilized for treatments in oncology and Infectimune, for treatments in infectious disease.  When paired with an antigen, which is a disease-related protein that is recognizable by inducing,the immune system, Versamune and Infectimune have both been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD4+CD4 helper and CD8+CD8 killer T cells, a specific sub-type of T cell that is more effective at killing infected or target cells. WeInfectimune is also designed to promote the induction of disease-specific neutralizing antibodies.  PDS01ADC is an investigational tumor targeting IL-12 that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment. Versamune plus PDS01ADC enhances the proliferation, potency and longevity of antigen specific multifunctional CD8 T cells in the tumor microenvironment and works synergistically to overcome tumor immune suppression.

Recent Developments

In December 2022, we executed an exclusive global license agreement with Merck KGaA, Darmstadt, Germany for the tumor targeting IL12 fused antibody drug conjugate, M9241, which joined our pipeline as PDS01ADC. PDS01ADC is a novel investigational tumor-targeting fusion protein of Interleukin 12 that enhances the proliferation, potency, infiltration and longevity of T cells in the tumor microenvironment and is therefore designed to overcome the limitations of cytokine therapy which today have developed multiple therapies, based on combinationsresulted in high toxicity and limited therapeutic potential.  The proprietary combination of Versamune and disease-specific antigens,plus PDS01ADC is designed to trainovercome tumor immune suppression utilizing a different mechanism from immune checkpoint inhibitors (ICI). The ownership of both assets we believe will streamline the registrational process and its use.  The combination of Versamune® and IL-12 to overcome immune systemsuppression is patented by PDS Biotech.  In a Phase 2 National Cancer Institute (NCI)-led clinical trial in ICI resistant patients, the combination of PDS0101 and PDS01ADC administered with an investigational bi-functional ICI resulted in a median overall survival of approximately 20 months, which compares favorably to recognize diseased cells and effectively attack and destroy them. We continue to advance our pipelinethe historical median survival of candidates to address a wide range of cancers including3-4 months reported in ICI resistant HPV-positive cancers (anal, cervical,when treated with ICIs and best reported median survival to date with systemic therapy of 8.2 months in ICI resistant head and neck penile, vaginal, vulvar) and breast, colon, lung prostate and ovarian cancers. Our Infectimune -based vaccines have demonstrated the potential to induce, not only robust and durable neutralizing antibody response, but also powerful T cell responses including long-lasting memory T cell responses. Our infectious disease candidates are of potential interest for use in universal influenza vaccines.cancer.

In May 2022,February 2023, we announced a successful completion of a Type B meeting with the FDA for the triple combination of PDS0101 and PDS01ADC with an FDA-approved immune checkpoint inhibitor for the treatment of recurrent/metastatic, ICI resistant head and neck cancer that two abstracts had beenis positive for the human papilloma virus (HPV) type 16. In recent interactions with the FDA, we confirmed the required contents of a clinical protocol for the potential registrational trial.

In June 2023, an abstract was presented at the 20222023 American Society of Clinical Oncology Annual Meeting:Oncology: Abstract number 6041,6012, Safety and Efficacy of Immune Checkpoint Inhibitor (ICI) Naïve Cohort from Study of PDS0101 a novel type 1 interferon and CD8+ T cell activating immunotherapyPembrolizumab in HPV16-Positive Head and Neck Squamous Cell Carcinoma (HNSCC). The abstract was also selected as one of the featured posters reviewed by an expert panel in the Head and Neck Cancer discussion session.

In September 2023, data on our investigational universal flu vaccine, PDS0202, were presented at the 9th European Scientific Working Group on Influenza (ESWI) conference. These data demonstrated broad neutralization across multiple influenza strains and provided protection against infection after challenging animals not previously exposed to flu with lethal doses of the pandemic H1N1 flu virus.

In October 2023, data demonstrating PDS0101 in combination with pembrolizumabstandard-of-care (SOC) chemoradiotherapy was associated with a rapid decline in subjects with recurrent/metastatic HPV16-positive squamous cell carcinoma (HNSCC) and Abstract number 2518,human papillomavirus circulating cell-free DNA (ctHPV-DNA), a potential predictive biomarker of treatment response. The data from the IMMUNOCERV Phase II evaluation of2 clinical trial were featured in an oral presentation at the American Society for Radiation Oncology Annual Meeting.

In October 2023, updated interim data based on an August 2nd cut off from our VERSATILE-002 Phase 2 clinical trial evaluating the combination of PDS0101 M9241, and bintrafusp alfa with HPV16+ malignancies. Also in May 2022, we announced expansion of our VERSATILE-002 clinical trial into Europe and in June 2022, we announced the U.S. Food and Drug Administration (the “FDA”) had granted Fast Track designation to our lead candidate PDS010 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab). which is the FDA-approved standard of care for first-line treatment of recurrent/ metastatic head and neck cancer was presented.  The FDA’s Fast Track designation is designeddata was presented at a Company-sponsored key opinion leader roundtable.

In October 2023, interim safety and immune response data was presented for the first-in-human Phase1/2 clinical trial evaluating PDS01ADC in combination with current SOC chemotherapy, docetaxel, to aidtreat metastatic castration sensitive and castration resistant prostate cancer. The data was featured in an oral presentation at the development and to expedite11th Annual Meeting of the review of drug candidate applications that would potentially treat serious or life-threatening conditions. International Cytokine & Interferon Society.

In order to receive Fast Track designation,October 2023, immune response data from a product must also demonstrate the potential to address an unmet medical need. Treatments granted this designation are given the opportunity to have more frequent meetings with the FDA throughout the entire dug development and review process, with the goal of moving promising new drugs more rapidly through the process. It also provides the opportunity to submit sectionspreliminary analysis of a New Drug Application (the “NDA”) on a rolling basis, where the FDA may review portions of the NDA as they are received instead of waiting for the entire NDA submission. In addition, Fast Track designated products are eligible for priority reviewsubset if patients in our VERSATILE-002 Phase 2 clinical trial was presented at the time of NDA or Biologics License Application submission.

In July 2022, we announced the presentation of universal flu vaccine preclinical dataEuropean Society for PDS0202 at the 41st American Society of Virology meeting: Abstract number 3733830, Infectimune™ enhances antibodies elicited by COBRA hemagglutinin influenza vaccine.Medical Oncology Congress 2023.

Clinical Candidate Pipeline

VERSATILE-002: PDS0101 + KEYTRUDA®

In November 2020, our VERSATILE-002 Phase 2 clinical trial evaluating the combination of PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA®KEYTRUDA® (pembrolizumab) which is the FDA-approved standard of care for first-line treatment of recurrent/ metastatic head and neck cancer commencedcommenced.  Enrollment in stage 2 of 2 for the ICI naïve arm and is actively recruiting patients.the ICI resistant arms are complete. The clinical trial will evaluate the efficacy and safety of this therapeutic combination as a first-linefirst and second line treatment in patients with recurrent or metastatic head and neck cancer and high-risk human papillomavirus-16 (HPV16) infection.

In this PDS Biotech-sponsored trial patients whose cancer has returned or spread following initial treatment or spread will be treated with the combination of PDS0101 and KEYTRUDA®KEYTRUDA® to evaluate if the addition of PDS0101 might improve the efficacy reported in published studies of KEYTRUDA®KEYTRUDA® alone. Patients in the trial will receive a total of 5 cycles of combination therapy in the context of standard of care KEYTRUDA® therapy administered every three weeks until disease progression. The primary endpoint of VERSATILE-002 is the objective response rate –rate– or ORR – at six months following initiation of treatment. There are two cohorts in the trial. Cohort 1 is for patients who have yet to be treated with aan immune checkpoint inhibitor (CPI(ICI naïve) and cohort 2 which consists of patients who have failed immune checkpoint inhibitor therapy (CPI refractory)(ICI resistant).

In February 2022, we announced we had achieved the preliminary efficacy milestone of at least four or more objective responses of the first 17 patients in the CPIICI naïve arm which now allowsthat allowed that arm to proceed to full enrollment. We also announced detailed preliminary safety data which showed that the combination is well tolerated without evidence of enhanced or significant toxicity in the first 18 patients in the CPIICI naïve arm. We continue to enroll patientshave completed enrollment in the first stageStage 1 of the CPI refractory arm.ICI resistant arm and we are waiting for sufficient follow up to conduct the futility analysis.

In MayJune 2022, we announcedpresented additional preliminary efficacy and safety data from this trial at the ASCO Annual Meeting.Meeting (Weiss J et al. J Clin Oncol 40, 2022 (suppl 16; abstr 6041)). The abstract provided preliminary data on 19 patients (safety) with available imaging data for 17 of the 19 patients (efficacy). Data on 17 patients was presented. Highlights from the abstract were as follows:


Response
Confirmed and unconfirmed response rates thus far*far (tumor shrinkage greater than 30%) seen in 7/17 (41.2%) patients in comparison to the published results of approximately 19% for approved checkpoint inhibitors,ICIs, used as monotherapy for recurrent or metastatic head and neck cancer, with 2 of the 7 having complete responses (CR)

Stable disease (SD) was reported in 6/17 (35.3%) patients, with 4 of the 6 (67%) experiencing tumor shrinkage of less than 30%

Clinical efficacy (ORR*(ORR + SD) was seen in 13/17 (76.5%) patients

Progressive/ongoing disease was reported in 4/17 (23.5%) patients


Patients had received a median of 4/5 doses of PDS0101 (range 1-5) and 9/35 doses of KEYTRUDA®KEYTRUDA® (range 1-18)

There were no treatment-related adverse events greater than or equal to Grade 3 (N=19)

No patients required dose interruption or reduction on the combination treatment

No patients discontinued the combination treatment

At 9 months of follow up (median not yet achieved):

Progression free survival (PFS) rate was 55.2%

Overall survival (OS) rate was 87.2%

noNo control or comparative studies have been conducted between checkpoint inhibitorsICIs and PDS0101

In May 2022, we announced the expansion ofexpanded this trial into Europe and in June 2022, as described above, we received Fast Track designation from the US FDA for PDS0101 in combination with pembrolizumab.

In August 2022, we announced our independent Data Monitoring Committee (DMC) met and evaluated data from 43 patients and noted there were no Grade 3 or greater treatment-related adverse events attributed to the combination. The DMC recommended continuing the trial with no modifications.

In October 2022, we announced the results of an end-of-phase 2 meeting with the FDA for PDS0101 in combination with KEYTRUDA®. We are currently evaluatinghave completed the guidance onplan for  the key elements of thePhase 3 clinical program that will support the submission of a Biologics License ApplicationBLA for PDS0101.PDS0101 and have submitted to the FDA.

In December 2022, we completed the first stage of enrollment in the ICI resistant arm. Cohort follow-up is in progress that will permit a futility analysis to determine progression to stage 2 enrollment is in progress.

In May 2023, we completed enrollment in the ICI naïve arm. We filed our amended IND with the FDA in the third quarter of 2023. In October 2023, we received feedback from the FDA on the amended IND. Later in October, as part of business development discussions, we received insights from a potential business partners on the Phase 3 clinical protocol. The clinical and medical teams are currently evaluating this feedback and therefore plan to initiate a Phase 3 trial, VERSATILE-003 in the first quarter of 2024.

In June 2023, an abstract was presented at the 2023 American Society of Clinical Oncology: Abstract number 6012, Safety and Efficacy of Immune Checkpoint Inhibitor (ICI) Naïve Cohort from Study of PDS0101 and Pembrolizumab in HPV16-Positive Head and Neck Squamous Cell Carcinoma (HNSCC). The abstract was also selected as one of the featured posters to be reviewed by an expert panel in the Head and Neck Cancer discussion session. Data on 34 patients was presented. The data from the abstract is as follows:


Estimated 12-month overall survival rate was 87.1%. Published results are 36-50% with approved ICIs used alone.

Median progression-free survival was 10.4 months (95% CI 4.2, 15.3). Published results are median PFS of 2-3 months for approved ICIs when used as monotherapy in patients with similar PD-L1 levels.

A disease control rate (disease stabilization or tumor shrinkage) of 70.6% (24/34)

Confirmed and unconfirmed objective response rate is 41.2% (14/34 patients), which is identical to the preliminary response rate data PDS Biotech previously reported at ASCO 2022 (7/17 patients). To date these responses have been confirmed in nine of the 34 patients (26.5%), including one complete response.

15/34 patients (44.1%) had stable disease.

9/34 patients (26.5%) had progressive disease.

4/48 (8.3%) of patients had a Grade 3 treatment-related adverse event (TRAE). No Grade 4 or higher TRAEs were observed.

In October 2023, at a key opinion roundtable updated interim data was presented based on an August 2nd cut off from our VERSATILE-002 Phase 2 clinical trial evaluating the combination of PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) which is the FDA-approved standard of care for first-line treatment of recurrent/ metastatic head and neck cancer. Data on 52 patients was presented. The data from the roundtable based on investigator assessment were as follows:

Highlights from the ICI naïve cohort include:


24-month overall survival (OS) rate is 74%; published 24-month survival rate of less than 30% for approved ICI.

12-month OS rate is 80%; published results of 30-50% with approved ICIs1.

Tumor shrinkage seen in 60% (31/52) of patients.

Confirmed overall response rate (ORR) is 27% (14/52) to date.

Median progression-free survival (PFS) is 8.1 months to date; published results of 2-3 months PFS with approved ICIs.

13% (8/62) of patients experienced Grade 3 treatment-related adverse events (TRAE) and 0% (0/62) experienced Grade 4 or 5 TRAE; published results report 13-17% Grade 3-5 TRAE with approved ICI monotherapy.

60% (33/55) of patients have CPS score of 1-19 (who generally have a weaker response to KEYTRUDA®), and 40% (22/55) have CPS score >20 (who generally have a higher response to KEYTRUDA®).

Highlights form the ICI refractory cohort include:


The 12-month OS rate is 56%. The published median 12-month OS rate is 17% with no salvage chemotherapy following tumor progression on ICI (ICI Resistant).

0% (0/21) confirmed ORR suggests that PDS0101’s impact on survival does not appear to be dependent on tumor shrinkage.

4% (1/25) of patients experienced Grade 3 TRAE and 0% (0/21) patients experienced Grade 4 and 5 TRAE.

National Cancer Institute: PDS0101+ M9241 (now PDS01ADC) +Bintrafusp Alfa

In June 2020, the first patient was dosed under a PDS0101 Cooperative Research and Development Agreement (CRADA), in the NCI led Phase 2 clinicalinvestigator-initiated trial evaluating PDS0101 with NHS-IL12 (M9241),an IL-12 ADC now PDS01ADC, and M7824 (Bintrafusp alfa), both of which areis owned by EMD Serono (Merck KGaA) in patients with advanced/refractoryadvanced  HPV-positive cancers who have failed prior treatment. In February 2021, we announced that the NCI’s Phase 2 clinical trial of PDS0101 for the treatment of advanced/refractoryadvanced HPV-positive cancers had achieved its preliminary objective response target in patients naïve to checkpointcheck point inhibitors which allowed for full enrollment of approximately 20 patients in this group. In addition, based on promising results in the CPIICI naïve arm, the trial was amended to allow enrollment of a separate cohort of checkpoint inhibitor-refractoryIC -resistant patients for assessment of safety and activity of the triple combination. The trial has been closed for enrollment. Preliminary efficacy assessment of the triple combination in this added group of 20 checkpoint inhibitor refractory29 ICI resistant patients ishas been completed and evaluation of long-term patient survival ongoing.

Preclinical study results arising from this CRADA were published in the Journal for ImmunoTherapy of Cancer, Immunomodulation to enhance the efficacy of an HPV therapeutic vaccine (Journal for ImmunoTherapy of Cancer 2020;Cancer2020;8:e000612. doi:Doi:10.1136/ jitc-2020-000612), indicatingand indicate that PDS0101 generated both HPV-specific T cells and anassociatedantitumor response when used as a monotherapy. When PDS0101 was combined with the two other novel clinical-stage anti-canceragents, Bintrafusp Alfa and M9241 (which is now owned by us and referred to as PDS01ADC), the preclinical data suggested that all three therapeutic agents workedsynergistically to provide superior tumor T cell responses and subsequent tumor regression when compared to any of the agents alone or the 2-component combinations. If theThe published preclinical data demonstrating powerful activity of the triplecombination is successfully confirmedappears to be corroborated in the ongoing Phase 2 trial, and this triple combination could form the basis of a unique platform providing improved cancer treatments across multiple cancers.

In June 2021, at the American Society of Clinical Oncology (ASCO) conference the NCI announced interim data in this trial which included, data in both CPI naïve and refractory patients.  In the CPI naïve group 83% (5/6) of patients had an objective response, and 1 subject had achieved a complete response with no evidence of disease.  100% of the CPI naïve patients were alive at a median duration of 8 months.  In the CPI refractory group 42% (5/12) of patients had an objective response, and 1 subject had achieved a complete response with no evidence of disease.  10/12 (83%) of CPI refractory patients were alive at a median duration of 8 months.  An update provided in January 2022 showed as of December 31, 2021, that >40 subjects had been recruited into the trial and 30 HPV16-positive patients had been evaluated.  The median survival of all patients (3:1 CPI refractor to naïve) was 12 months and progressing.  The historical survival of CPI naïve and CPI refractory advanced HPV-positive cancers when treated with CPI are 7-11 months and 3-4 months, respectively.

In June 2022, at the 2022 ASCO Annual Meeting, wethe NCI provided an update to the preliminary data presented at the 2021 meeting.meeting (Strauss J et al. J Clin Oncol 40, 2022 [suppl 16; abstr 2518]). This included data from 30 HPV16-positive patients and highlights were as follows:


Objective response (OR = >30% tumor reduction) was seen in 88% (7/8) of patients with checkpoint-naiveICI naive disease; 4/7 (57%) patients’ responses are ongoing (median 17 months).

With checkpoint refractoryICI resistant patients: M9241PDS0301 dosing appears to affect response rates, with 5/8 (63%) patients receiving M9241PDS0301 at 16.8 mcg/kg achieving an OR compared to 1/14 (7%) patients who received M9241PDS0301 at 8 mcg/kg achieving an OR; 4/6 (67%) patients’ responses are ongoing (median 12 months).

Tumor reduction was seen in 45% (10/22) of patients with checkpoint-refractoryICI resistant disease, including patients receiving high or low dose M9241.PDS0301.

In checkpoint refractoryICI resistant patients treated with high or low dose M9241,PDS0301, survival outcomes were similar (p=0.96 by Kaplan Meier analysis). At a median of 12 months of follow up 17/22 (77%) of patients were alive.

In checkpointICI naïve patients 6/8 (75%) were alive at median 17 months of follow up.

Similar OR and survival were seen across all types of HPV16-positive cancers.

Preliminary safety data: 13/30 (43%) of patients experienced Grade 3 treatment-related adverse events (AEs), and 2/30 patients (7%) experienced Grade 4 AEs. There were no grade 5 treatment-related AEs.

The study results to date strongly suggest, in agreement with the published preclinical studies, that all 3 drugs contribute to the clinical outcomes.

We believe the study results to date strongly suggest, in agreement with the published preclinical studies, that all 3 drugs contribute to the clinical outcomes.

In September 2022, we announced,determined, in agreement with the NCI, thatto select the CPI refractoryICI resistant patients had been selected as the preferred treatment group in the on-going PDS0101-based triple combination therapy in advanced HPV-positive cancers and the trial was closed to further enrollment given the CPI refractoryICI resistant arm hashad been fully recruited. We and the NCI hope to meet with the FDA in the coming months to discuss the registrational path forward for the combination therapy as a potential third-line treatment for CPI refractory HPV-positive cancers.

In October 2022, we announced expandedpresented additional interim data as follows:


Survival data:  66% (19/29) of HPV16-positive CPI refractoryICI resistant patients in the cohort were alive at a median follow up of 16 monthsmonths.

Safety profile: 48% (24/50) patients experienced Grade 3 treatment-related adverse events (AEs), and 4% (2/50) patients experienced Grade 4 AEs. There were no Grade 3 treatment-related AEs.

HPV16-positive CPIICI naïve patients: 75% (6/8) were alive at a median follow up of 25 months and 38% (3/8) of responders had a complete response.

In December 2022, we presented interim data as follows:


Median OS was 21 months in 29 checkpoint inhibitor resistant patients who received the triple combination. The reported historical median OS in patients with ICI resistant disease is 3-4 months seen with checkpoint inhibitors and best reported median survival to date with systemic therapy of 8.2 months in ICI resistant head and neck cancer.

In ICI naïve subjects, 75% remain alive at a median follow-up of 27 months.  As a result, median OS had not yet been reached. Historically median OS for similar patients with platinum experienced ICI naïve disease is 7-11 months.

Objective response rate (ORR) in ICI resistant patients who received the optimal dose of the triple combination is 63% (5/8).  In current approaches ORR is reported to be less than 10%.

ORR in ICI naïve patients with the triple combination is 88%. In current approaches ORR is reported to be less than 25% with FDA-approved ICIs in HPV-positive cancers.

Safety data had not changed since October’s update. 48% (24/50) of patients experienced Grade 3 (moderate) treatment-related adverse events (AEs), and 4% (2/50) patients experienced Grade 4 (severe) AEs, compared with approximately 70% of patients receiving the combination of ICIs and chemotherapy reporting Grade 3 and higher treatment-related AEs.

In February 2023, we announced the successful completion of a Type B meeting with the FDA for the combination therapy of PDS0101, PDS01ADC, and an FDA-approved immune checkpoint inhibitor for the treatment of recurrent/metastatic HPV-positive ICI-resistant head and neck cancer. We confirmed the required contents of the trial design for a potential registrational trial of the combination.

In November 2023, we released updated interim survival data as follows:


75% of immune checkpoint inhibitor (ICI) naïve patients remain alive at 36 months; published median overall survival (OS) in similar patients is 7-11 months

12-month survival rate in (ICI) resistant patients is 72%

Median OS in ICI resistant HPV-positive patients is approximately 20 months; published median OS is 3.4 months

In November 2022, we announced data from this trial was included in a poster presentation being presented at the 2022 SITC Annual Meeting which included the following:


9 of the 17 patients have nowhad completed a Day 170 post-treatment Positron Emission Tomography, Computed Tomography (PET CT) scan to assess the status of the cancer. This includesincluded 78% (7/9) of treated patients with advanced cervical cancer (FIGO stage III or IV).

100% (9/9) of patients treated with the combination of PDS0101 and CRT had an objective response.

89% (8/9) of patients treated with the combination of PDS0101 and CRT demonstrated a complete response (CR) on Day 170 by PET CT. One patient who received 3 of the 5 scheduled doses of PDS0101 showed signs of residual disease. One patient who had a CR died from an event unrelated to either their underlying disease or treatment.

1-year disease-free survival and 1-year overall survival of 89% (8/9) in patients treated with the combination of PDS0101 and CRT
CRT.

As previously reported, data confirm PDS0101 treatment activates HPV16-specific CD8+CD8 T cells. This increase was not seen in patients who did not receive PDS0101. The increase in HPV16-specific T cells generated by the treatment is positively correlated with tumor cell death, suggesting cytotoxic CD8+CD8 T cells are important mediators of antigen-specific immunity.

The data affirm that PDS0101 activates Type 1 interferon pathway in humans, mimicking the mechanism previously demonstrated in preclinical studies in animal modelsmodels.

Toxicity of PDS0101 remains limited to low-grade local injection site reactions.

In October 2023, data demonstrating PDS0101 in combination with standard-of-care (SOC) chemoradiotherapy was associated with a rapid decline in human papillomavirus circulating cell-free DNA (ctHPV-DNA), a potential predictive biomarker of treatment response. The data from the IMMUNOCERV Phase 2 clinical trial were featured in an oral presentation at the American Society for Radiation Oncology Annual Meeting which included the following:


Earlier and greater proportion of ctDNA clearance with PDS0101 plus chemoradiation (CRT) vs. SOC CRT alone (81.3% clearance after 3 weeks vs. 30.3% with SOC (p=0.0018), and 91.7% of clearance at 5 weeks vs. 53.1% with SOC (p=0.0179).

Baseline ctDNA levels correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage and lymph node involvement; 100% of patients treated with PDS0101 had cancer that had spread to the lymph nodes.

Mayo Clinic: PDS0101 Monotherapy and in combination with KEYTRUDA®

In February 2022, we announced the initiation ofinitiated an Investigator-Initiated Trial (ITT), MC200710, for PDS0101 alone or in combination with the immune checkpoint inhibitor, KEYTRUDA®, in patients with HPV-positive oropharyngeal cancer (HPV(+)OPSCC) at high risk of recurrence. The trial is being led by Drs. David Routman, Katharine Price, Kathryn Van Abel, and Ashish Chintakuntlawar ofat Mayo Clinic, a nationally and internationally recognized center of excellence for the treatment of head and neck cancers. We believe that this upcoming trial not only broadens our addressable patient population of those affected by the increasing incidence of HPV(+)OPSCC, but also allows us to better understand the activity of PDS0101 alone or in combination with KEYTRUDA® in earlier stages of disease.  This trial is currently open for enrollment.

23

In this trial, treatment will be administered before patients proceed to transoral robotic surgery (TORS) with curative intent. Treatment in this setting is referred to as neoadjuvant treatment. PDS0101 has been shown to induce CD8+ killer T cells that target and kill HPV-positive cancers, either alone or in combination with checkpoint inhibitorsICIs in preclinical studies, and in combination in clinical studies of patients with advanced recurrent/metastatic HPV-positive cancers.  This trial will explore whether PDS0101 with or without checkpoint inhibition may increase HPV-specific anti-tumor responses, potentially resulting in tumor shrinkage, pathologic regression, and decreases in circulating tumor DNA (ctDNA).

Our clinical development strategy of combining PDS0101 with standard of care treatment is designed to mitigate risk in our proof-of-concept phase 2 trials.  It is also designed to demonstrate the potential for significantly enhanced clinical benefit to patients over the standard of care, without compounding toxicity. If we achieve this goal, we believe that we will have a clear path towards commercialization of PDS0101 in multiple indications.  After initial commercial approval, our strategy of combining PDS0101 with standard of care also positions us for rapid market penetration and expansion.
PDS0102

Other Versamune® -Based Products in Development:

PDS0102

PDS0102 is an investigational immunotherapy utilizing tumor-associated and immunologically active T cell receptor gamma alternate reading framed protein (TARP) from the NCI. PDS0102 is designed to treat TARP-positiveTARP-associated cancers including, acute myeloid leukemia (AML), prostate and breast cancer. In our preclinical work, in the administration of PDS0102, the Versamuine+TARP antigen combination led to the induction of large numbers of polyfunctional tumor targeted killer T cells. In addition, the TARP tumor antigen alone has already been studied at the NCI in men with prostate cancer and been shown to be safe, immunogenic with slowing tumor growth rates (NCT00972309). We are evaluating the next steps in the clinical development of PDS0102 and are seeking nondilutive fundingfinancings to progress to humanmove the program into clinical trials.

PDS0103

PDS0103

In April 2020, the above mentioned PDS Biotech-NCI CRADA was expanded beyond PDS0101 to include clinical and preclinical development of PDS0103. PDS0103 is an investigational immunotherapyimmune therapy owned by usPDS Biotech and designed to treat cancers associated with the mucin-1, or MUC-1,MUC1, oncogenic protein. These include cancers such as ovarian, breast, colorectal and lung cancers. PDS0103 combines Versamune with novel highly immunogenic agonist epitopes of MUC-1MUC1 developed by the NCI and licensed by PDS. PDS0103 is currently in late preclinical development.the tech transfer and clinical scale up and manufacturing stage.

MUC1 is highly expressed in several types of cancer and has been shown to be associated with drug resistance and poor disease prognosis in breast, colorectal, lung and ovarian cancers, for which PDS0103 is being developed. Expression of MUC-1MUC1 is often associated with poor disease prognosis, due in part to drug resistance. In preclinical studies, and similarly to PDS0101, PDS0103 demonstrated the ability to generate powerful MUC1-specific CD8 killer T cells. In the first quarter of 2022, we held a pre-IND meeting with the FDA on PDS0103 and we are prepared to submit our IND package inby the first half of 2023.2024. However, the actual submission date may potentially be impacted by the outcomeallocation of our meetings withresources to initiate the FDA on the timing of a pivotal trial for PDS0101. Our primary goal is commercialization of PDS0101, and allocation of resources to implement an earlier than planned start of a registrational trial may delay PDS0103 initiation.

Our current pipeline of Versamune based therapies is as follows:

IL-12 Oncology Immunocytokine Pipeline

PDS01ADC (formerly known as PDS0301/M9241 and NHS-IL-12 ) is a novel investigational IL12 fused antibody drug conjugate (IgG1), tumor-targeting interleukin 12 (IL-12) immune-cytokine that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment. Together with Versamune based immunotherapies PDS01ADC works synergistically to overcome tumor immune suppression and to promote a targeted T cell attack against cancers. As with Versamune, PDS01ADC is given by a simple subcutaneous injection. Clinical data suggests the addition of PDS01ADC to Versamune based immunotherapies may demonstrate significant disease control in advanced cancer patients by shrinking tumors and/or prolonging life.

With the exclusive global license agreement with Merck KGaA, Darmstadt, Germany for PDS01ADC, we believe we have simplified our registrational pathway for the NCI-led triple combination by owning both PDS0101 and PDS01ADC and combining these agents with an FDA approved ICI.  PDS01ADC has been designed to overcome the limitations of cytokine therapy as explained above, and based on extensive preclinical studies performed at the NCI evaluating PDS01ADC as a monotherapy and also in combinations with established standard of care treatments for cancer, we believe that PDS01ADC has significant potential as a cytokine therapy independent of Versamune.  Based on the informative preclinical studies, a number of ITT Phase 2 trials are currently in progress at the NCI, some of which are outlined below:


Phase II Study Evaluating ICI Naïve and Resistant Patients with HPV-positive malignancies treated with PDS01ADC, PDS0101 and bintrafusp alfa.

A Phase II Study Evaluating T-Cell Clonality After Stereotactic Body Radiation Therapy Alone and in Combination with the Immunocytokine PDS01ADCin Localized High and Intermediate Risk Prostate Cancer Treated with Androgen Deprivation Therapy

A Phase I/II Study of PDS01ADC in Combination with Docetaxel in Adults with Metastatic Castration Sensitive and Castration Resistant Prostate Cancer

Phase I/II of PDS01ADC going forward as a Monotherapy in Advanced Kaposi Sarcoma

Phase I/II of PDS01ADC in Combination of with a Histone Deacetylase (HDAC) Inhibitor in ICI resistant MUC1-positive colon and bladder cancers among others

In October 2023, interim safety and immune response data was presented for the first-in-human Phase1/2 clinical trial evaluating PDS01ADC in combination with current SOC chemotherapy, docetaxel, to treat metastatic castration sensitive and castration resistant prostate cancer. The data was featured in an oral presentation at the 11th Annual Meeting of the International Cytokine & Interferon Society. Data presented as follows:


Decrease in PSA levels was seen in all patients at all three tested doses of PDS0301 and 61% of patients had at least a 60% decrease in PSA levels.

All doses of the combination were well-tolerated with one patient experiencing Grade 4 neutropenia.

Administration of the combination was associated with decreases in T reg cells and increases in activated natural killer (NK) cells, memory CD8 T cells, proliferating CD4 and CD8 T cells and cytokines INF-γ and Interleukin 10 (IL-10).

The changes in immune responses with the combination were independent of the PDS0301 dose.

We are working closely with the NCI to determine the best pathway forward for the prioritized PDS01ADC studies, as well as evaluating the use of PDS01ADC in combination with other Versamune based clinical candidates.

Our current pipeline of IL12  fused antibody conjugated PDS01ADC based therapies is as follows:

Infectimune Development Strategy

We believe that the key differentiating attributes of the Infectimune platform technology are strong induction of CD8+CD8 and CD4+CD4 T cells as well as antibodies which can be leveraged to improve treatment and preventive options in several infectious disease indications. In January 2022, we announcedpresented preclinical data on our universal flu program sponsored by the National Institute of Allergy and Infectious Disease (NIAID) demonstrating the potential of the Infectimune technology with computationally designed influenza proteins developed by the laboratory of Dr. Ted Ross at the University of Georgia to generate broadly protective anti-influenza immune responses across multiple strains of influenza. This data as well as our COVID-19 data has provided a unique opportunity to highlight Infectimune’s potentially transformative utility in the development of more broadly effective and longer lasting protective vaccines. Current preventive and prophylactic vaccine approaches and technologies predominantly focus on creating strong induction of antibody responses. However, the induction of T cell responses, in addition to antibody responses, provides more durable and broad protection against infectious diseases.

Based on the promising data recently announced with the universal seasonal flu vaccine and the current focus of the NIAID in developing more effective flu vaccines, we have decided to opportunistically focus our near-term infectious disease activities to align with the interests of the NIAID Collaborative Influenza Vaccine Innovation Centers (CIVICs) program. This will involve development of a universal seasonal flu vaccine and the potential development of a universal pandemic influenza vaccine based on similar computationally designed antigens as have shown promise with Infectimune.

In July 2022, we announced the presentation of universal flu vaccine preclinical data for PDS0202 at the 41st American Society of Virology meeting: Abstract number 3733830, Infectimune™Infectimune enhances antibodies elicited by COBRA hemagglutinin influenza vaccine. We are evaluating the next steps in the clinical development and funding for PDS0202.

The results for Infectimune based vaccines were published in two separate articles in the peer reviewed journal Viruses in February 2023: 1. preclinical studies demonstrating complete protection against sickness after lethal challenge with live SARS-CoV-2 or influenza viruses (Gandhapudi SK et al. Viruses 2023, 15, 432) and 2. Dramatically enhanced CD4 T cell responses to recombinant influenza proteins compared to leading commercial vaccine adjuvants (Henson TR et al. Viruses 2023, 15, 538).
22
In September 2023, data on our investigational universal flu vaccine, PDS0202, were presented at the 9th European Scientific Working Group on Influenza (ESWI) conference. These data demonstrated active neutralization across multiple influenza viruses and provided protection against infection and weight loss after challenging with high doses of H1N1 viruses not previously exposed to flu.

Our current pipeline of Versamuneand Infectimune based therapies is as follows:

We have never been profitable and have incurred net losses in each year since inception. Our net losses were $21.7$32.0 million, and $10.6$21.7 million for the nine months ended September 30, 20222023 and 2021,2022, respectively. As of September 30, 2022,2023, we had an accumulated deficit of $82.4$133.6 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with these operations.

As of September 30, 2022,2023, we had $71.6$54.3 million in cash and cash equivalents.

Our future funding requirements will depend on many factors, including the following:


the timing and costs of our planned clinical trials;


the timing and costs of our planned preclinical studies of our Versamune® platform;


the outcome, timing and costs of seeking regulatory approvals;


the terms and timing of any future collaborations, licensing, consulting or other arrangements that we may enter into;


the amount and timing of any payments we may be required to make in connection with the licensing, filing, prosecution, maintenance, defense and enforcement of any patents or patent applications or other intellectual property rights; and


the extent to which we license or acquire other products and technologies.

SELECTED FINANCIAL OPERATIONS OVERVIEW

Revenue

We have not generated any revenues from commercial product sales and do not expect to generate any such revenue in the near future. We may generate revenue in the future from a combination of research and development payments, license fees and other upfront payments or milestone payments.

Research and Development Expenses

Research and development expenses include employee-related expenses, licensing fees to use certain technology in our research and development projects, costs of acquiring, developing and manufacturing clinical trial materials, as well as fees paid to consultants and various entities that perform certain research and testing on our behalf. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the consolidated financial statements as prepaid or accrued expenses. Costs incurred in connection with research and development activities are expensed as incurred.

We expect that our research and development expenses will increase significantly over the next several years as we advance our platforms including Versamune based immuno-oncology, orIL12 Fused antibody drug candidates in oncology, and Infectimune based infectious disease candidates into and through clinical trials, pursue regulatory approval of our investigational candidates and prepare for a possible commercial launch, all of which will also require a significant investment in contract and internal manufacturing and inventory related costs.

The process of conducting human clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving marketing approval. The probability of successful commercialization of our drug candidates may be affected by numerous factors, including clinical data obtained in future trials, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

At this time the option has expired and Loan E and Loan F are no longer available to the Company under the Loan and Security Agreement . We may only use the proceeds of the Loans for working capital or general corporate purposes.

Each Loan matures on the 48-month anniversary following the applicable funding date unless accelerated pursuant to agreed upon events of default. Payments on the principal balance begin on October 1, 2024 and are paid monthly in the succeeding 24 months. The principal balance of each Loan bears a floating interest. The interest rate is calculated initially and, thereafter, each calendar month as the sum of (a) the per annum rate of interest from time to time published in The Wall Street Journal as contemplated by the Loan and Security Agreement, or any successor publication thereto, as the “prime rate” then in effect, plus (b) 5.75%; provided that, in the event such rate of interest is less than 4.00%, such rate shall be deemed to be 4.00% for purposes of calculating the interest rate.

Interest is payable on a monthly basis based on each Loan principal amount outstanding the preceding month.  We, at our option upon at least ten (10) business days’ written notice to the lenders, may prepay all (and not less than all) of the outstanding Loan by simultaneously paying to each lender an amount equal to (i) any accrued and unpaid interest on the outstanding principal balance of the Loans; plus (ii) an amount equal to (A) if such Loan is prepaid on or before the Loan Amortization Date (as defined in the Loan and Security Agreement) applicable to such Loan, 3% of the then outstanding principal balance of such Loan, (B) if such Loan is prepaid after the Loan Amortization Date applicable to such Loan, but on or before the date that is 12 months after such Loan Amortization Date, 2% of the then outstanding principal balance of such Loan, or (C) if such Loan is prepaid more than 12 months after the Loan Amortization Date but prior to the stated maturity date applicable to such Loan, 1% of the then outstanding principal balance of such Loan; plus (iii) the outstanding principal balance of such Loan; plus (iv) all other sums, if any, that shall have become due and payable thereunder.  No prepayment premium will be applied to any outstanding balance of any Loan paid on the stated maturity date.

In connection with the Loan and Security Agreement, we issued Horizon Technology Finance Corporation and Powerscourt Investments XXV, LP warrants to purchase an aggregate total of 381,625 shares of our common stock at an initial exercise price of $3.6685 per share. Each warrant is classified as equity and is exercisable at any time for a period beginning on the date of grant and ending on the earlier of (A) 10 years from the date of grant, and (B) the closing of (A) (i) the sale, lease, exchange, conveyance or other disposition of all or substantially all of the our property or business, or (ii) its merger into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company), or any transaction (including a merger or other reorganization) or series of related transactions, in which more than 50% of the voting power of the Company is disposed of, in each case, for cash or for marketable securities meeting certain requirements as described in the applicable warrants.  The key assumptions used in Black-Scholes option pricing model were (i) expected term of 10 years, (ii) a risk-free rate of 3.11%, (iii) expected volatility of 93.8%, and (iv) no estimated dividend yield.

In April 2023, we received approximately $1.4 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant our participation in the New Jersey Technology Business Tax Certificate Transfer NOL program for tax year 2021.

As of September 30, 2022,2023, we had $71.6$54.3 million in cash and cash equivalents. Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the filing of this Quarterly Report on Form 10-Q.  Based on such evaluation and our current plans, which are subject to change, management believes that our existing cash and cash equivalents as of September 30, 2022 will be sufficient to satisfy our operating cash needs for at least one year after the filing of this Quarterly Report on Form 10-Q.

We plan to continue to fund our operations and capital funding needs through equity and/or debt financings. However, we cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or our existing stockholders. We may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our productclinical development or future commercialization efforts or grant rights to develop and market immunotherapies that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the filing of this Quarterly Report on Form 10-Q.  While we intend to finance our cash needs principally through collaborations, strategic alliances, or license agreements with third parties and/or debt or equity financings, there is no assurance that new financing will be available to us on commercially acceptable terms or in the amounts required, if at all. As such, we have concluded that substantial doubt exists about our ability to continue as a going concern for a period of at least 12 months from the date of the issuance of these unaudited condensed consolidated financial statements. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect.

Cash Flows

The following table shows a summary of our cash flows for each of the periods indicated (in thousands):

 Nine Months Ended September 30,  Nine Months Ended September 30, 
 2022  2021  2023  2022 
Net cash used in operating activities

Net cash provided by financing activities  24,581   48,889   5,610   24,581 
Net increase in cash and cash equivalents $6,400  $40,904  $(19,569) $6,400 

Net Cash Used in Operating Activities

Net cash used in operating activities was $18.2$25.2 million and $8.0$18.2 million for the nine months ended September 30, 20222023 and 2021,2022, respectively. The increase in net cash used in operating activities of $10.2$7.0 million was primarily due to an increase in net loss of $11.1$10.3 million, anreduced by the increase in the non-cash stock-based compensation expense of $2.4 million, offset by changes in the timing of working capital requirements, including changes in prepaid expenses of $1.1 million, and an increase in finance right to use asset of $0.3 million, offset by an increase in stock compensation of $1.4 million, an increase in amortization of debt discount of $0.1 million,other assets, accrued expenses and anaccounts payable. The increase in accounts payable, specifically, is primarily the result of $0.7 million.a dispute with a certain vendor and we are working towards resolving this dispute.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2023 was due to the receipt of net proceeds of $5.6 million due to the sale of common stock under the Sales Agreement. Net cash provided by financing activities for the nine months ended September 30, 2022 was primarily due to the receipt of net proceeds of $24.6 million due to a note payable.the Venture Loan.

Operating Capital Requirements

To date, we have not generated any product revenue. We do not know when, or if, we will generate any product revenue and we do not expect to generate significant product revenue unless and until we obtain regulatory approval and commercialize one of our current or future product candidates. We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our tablet vaccine candidates, and begin to commercialize any approved vaccine candidates. We are subject to all of the risks incident to the development of new products, and may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may harm our business. We expect to incur additional costs associated with operating as a public company and anticipate that we will need substantial additional funding in connection with our continuing operations.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the filing of this Quarterly Report. Our budgeted cash requirements in 20222023 and beyond include expenses related to continuing development and clinical studies.  We believe that our existing cash and cash equivalents as of September 30, 2022 are sufficient to continue operations and research and development programs for at least one year after the date of this Quarterly Report. Until we can generate significant cash from our operations, we expect to continue to fund our operations with available financial resources. These financial resources may not be adequate to sustain our operations. While we intend to finance our cash needs principally through collaborations, strategic alliances, or license agreements with third parties and/or debt or equity financings, there is no assurance that new financing will be available to us on commercially acceptable terms or in the amounts required, if at all. As such, we have concluded that substantial doubt exists about our ability to continue as a going concern for a period of at least 12 months from the date of the issuance of these unaudited condensed consolidated financial statements.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:


the initiation, progress, timing, costs and results of our planned clinical trials;


the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the recent COVID-19 pandemic, on our business operations, financial condition, results of operations and cash flows;


the outcome, timing and cost of meeting regulatory requirements established by the U.S. Food and Drug Administration, or FDA, the European Medicines Agency, or EMA, and other comparable foreign regulatory authorities;


the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;


the cost of defending potential intellectual property disputes, including patent infringement actions brought by third parties against us now or in the future;


the effect of competing technological and market developments;


the cost of establishing sales, marketing and distribution capabilities in regions where we choose to commercialize our products on our own; and


the initiation, progress, timing and results of our commercialization of our productclinical candidates, if approved, for commercial sale.

Please see the section titled “Risk Factors” elsewhere in the Quarterly Report and Annual Report for additional risks associated with our operations.

Purchase Commitments

We have no material non-cancelable purchase commitments with service providers as we have generally contracted on a cancelable, purchase order basis.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. GAAP. Our accounting policies are more fully described in Note 2 to the consolidated financial statements included in this Quarterly Report on Form 10-Q.  As described in Note 2, the preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Estimates are assessed each period and updated to reflect current information. Actual results may differ from these estimates under different assumptions or conditions. We believe that the discussion in our management’s discussion and analysis addresses our most critical accounting policies, which are those that are most important to the portrayal of our financial condition and results of operations and require management’s most difficult, subjective and complex judgments.

There have been no material changes to our critical accounting policies and estimates during the nine months ended September 30, 20222023 from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

Operations and Liquidity

While the potential economic impact brought by and over the duration of the COVID-19 pandemic may be difficult to assess or predict, the COVID-19 pandemic has resulted in significant disruption of global financial markets, which could in the future negatively affect our liquidity. In addition, a recession or market volatility resulting from the COVID-19 pandemic could affect our business. We have taken proactive, aggressive action throughout the COVID-19 pandemic to protect the health and safety of our employees and expect to continue to implement these measures until we determine that the COVID-19 pandemic is adequately contained for purposes of our business. We may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees. Given the nature and type of our short-term investments, we do not believe that the COVID-19 pandemic will have a material impact on our current investment liquidity.

Outlook and Impact of COVID-19 on our Business

In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020, the World Health Organization (WHO) declared COVID-19 a public health emergency. The Secretary of Health and Human Services declared a public health emergency on January 31, 2020, under section 319 of the Public Health Service Act (42 U.S.C. 247d), in response to the COVID-19 outbreak. On March 11, 2020, the WHO declared COVID-19 a pandemic and on March 13 the President declared a national emergency in response to the pandemic. The full impact of the COVID-19 pandemic is unknown and rapidly evolving. The COVID-19 pandemic has and could continue to negatively affect our liquidity and operations.  To date, two of the three recently initiated PDS0101 clinical trials were delayed, specifically as a result of the adverse impact the COVID-19 pandemic has had on clinical trial operations for cancer indications in the United States. The FDA issued and since updated guidance to assist sponsors in assuring the safety of trial participants, maintaining compliance with Good Clinical Practice (GCP) and minimizing risks to trial integrity.  Clinical trial sites have implemented institution-specific measures securing the safety of patients and staff to ensure the integrity of the trials in the face of the ongoing pandemic. All three studies have since been initiated despite the pandemic challenges; however, the evolving COVID-19 pandemic has impacted the pace of enrollment in clinical trials in general and we may be negatively affected with our trials. COVID-19 related travel and other restrictions may also impact the potential for on-site monitoring visiting and audits and inspections by us, third parties, and regulators. There may be shortages of site personnel and equipment necessary for the timely completion of our trials. We are providing support to address these challenges, but these mitigation measures may not overcome the obstacles that the pandemic has wrought which continue to impede progress of clinical trials.

Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our current cash reserves, leave us well-positioned to manage our business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain.2022.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Smaller Reporting Company

As of January 1, 2021, we arewere no longer an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. However, we remain a “smaller reporting company,” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended. We will cease to be a smaller reporting company if we have a non-affiliate public float in excess of $250 million and annual revenues in excess of $100 million, or a non-affiliate public float in excess of $700 million, determined on an annual basis. As a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not smaller reporting companies. We will continue to take advantage of some or all of the available exemptions.

ITEM 3:QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The primary objectives
Interest Rate Risk

We are exposed to market risks in the ordinary course of our investment activitiesbusiness and from changes in the interest rate on our debt borrowings. These market risks are principally limited to ensure liquidity and to preserve principal, while at the same time maximizing the income we receive from our cash and marketable securities without significantly increasing risk.interest rate fluctuations. As of September 30, 2022, we had2023, our cash equivalents consisted of $71.6 million that were held in a non-interest-bearing money operating accountbank deposits and an institutional U.S. Treasury money market fund.accounts and our debt is a variable interest rate instrument. Our primary exposure to market risk is interest rateincome sensitivity, which is affected by changes in the general level of U.S. interest rates. The primary objective of our investment activities is to preserve principal and liquidity while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the short-term maturitiesnature of our cash equivalentsinvestment portfolio and the low risk profile of our investments,debt agreement, we do not believe that an immediate 100 basis point changeincrease in interest rates would have a material effect on the fair market value of our portfolio, and, accordingly, we do not expect our operating results or cash equivalents. To minimizeflows to be materially affected by a sudden change in market interest rates.

Inflation Risk

Inflation generally affects us by increasing our cost of labor and pricing of contracts. We do not believe that inflation has had a material effect on our business, financial condition, or results of operations during the risk in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in institutional market funds that are comprised of U.S. Treasury and Treasury backed repurchase agreements.three months ended September 30, 2023.

ITEM 4:4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out, under the supervision of and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15 (e)) under the Securities Exchange Act of 1934, or the Exchange Act, as of the end of the period covered by this report. Based on the evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation identified above that occurred during the quarter ended September 30, 20222023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.OTHER INFORMATION

ITEM 1.LEGAL PROCEEDINGS

The information in Note 9 to the Condensed Consolidated Financial Statements contained in Part I, Item 1 of this Quarterly Report on Form 10-Q is incorporated herein by reference. There are no matters which constitute material pending legal proceedings to which we are a party other than those incorporated into this item by reference from Note 9 to our Condensed Consolidated Financial Statements for the quarter ended September 30, 20222023 contained in this Quarterly Report on Form 10-Q.

ITEM 1A.RISK FACTORS

With the exception of the risk factorsfactor noted below, there have been no material changes from our risk factors as previously reported in our Annual Report on Form 10-K for the year ended December 31, 2021.2022. However, any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our unaudited interim condensed consolidated financial statements and accompanying notes, our Annual Report on Form 10-K for the year ended December 31, 20212022 filed on March 31, 2022,28, 2023, including our financial statements and related notes contained therein, and the additional information in the other reports we file with the Securities and Exchange Commission. These risks may result in material harm to our business and our financial condition and results of operations. In this event, the market price of our common stock may decline and you could lose part or all of your investment. Additional risks that we currently believe are immaterial may also impair our business operations. Our business, financial conditions and future prospects and the trading price of our common stock could be harmed as a result of any of these risks.

We have identified conditions and events that raise substantial doubt regarding our ability to continue as a going concern.

We have incurred net losses and utilized cash in operations since inception. In addition, as of September 30, 2023, we had approximately $54.3 million in cash and cash equivalents, and during the nine months ended September 30, 2023, we used $18.2 million of cash in operations and expect to continue to incur significant cash outflows and incur future additional losses to execute our operating plan. While we intend to finance our cash needs principally through collaborations, strategic alliances, or license agreements with third parties and/or debt or equity financings, there is no assurance that new financing will be available to us on commercially acceptable terms or in the amounts required, if at all. Due to the uncertainty in securing additional funding, and the insufficient amount of cash and cash equivalents as of September 30, 2023, we have concluded that substantial doubt exists about our ability to continue as a going concern within one year after the date of the filing of this Quarterly Report. If we are currently operatingunsuccessful in securing sufficient financing, we may need to delay, reduce, or eliminate our research and development programs, which could adversely affect our business prospects, or cease operations.

Our unaudited condensed consolidated financial statements included in this Quarterly Report have been prepared on a periodgoing concern basis under which an entity is able to realize its assets and satisfy its liabilities in the ordinary course of economic uncertaintybusiness. The unaudited condensed consolidated financial statements do not give effect to any adjustments relating to the carrying values and capital markets disruption, which has been significantly impacted by geopolitical instability, an ongoing military conflict between Russiaclassification of assets and Ukraine, and record inflation. liabilities that would be necessary should we be unable to continue as a going concern within one year after the date that the financial statements are issued.

Our business, financial condition and results offuture operations could be materially adversely affected by any negative impactare dependent upon the successful entry into collaborations, strategic alliances, or license agreements with third parties and/or on the global economyidentification and capital markets resulting fromsuccessful completion of equity or debt financing and the conflictachievement of profitable operations at an indeterminate time in Ukraine, geopolitical tensions,the future. There can be no assurances that we will be successful in completing these collaborations or record inflation.alliances, equity or debt financing or in achieving profitability. As such, there can be no assurance that we will be able to continue as a going concern.

We are exposed to the risk of changes in social, geopolitical, legal, and economic conditions. The global economy has been, and may continue to be, negatively impacted by Russia’s invasion of Ukraine. As a result of Russia’s invasion of Ukraine, the United States, the European Union, the United Kingdom, and other G7 countries, among other countries, have imposed substantial financial and economic sanctions on certain industry sectors and parties in Russia. Broad restrictions on exports to Russia have also been imposed. These measures include: (i) comprehensive financial sanctions against major Russian banks; (ii) additional designations of Russian individuals with significant business interests and government connections; (iii) designations of individuals and entities involved in Russian military activities; and (iv) enhanced export controls and trade sanctions limiting Russia’sSubstantial doubt about our ability to import various goods.

Although the lengthcontinue as a going concern may materially and impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine has led to market disruptions, including significant volatility in commodity prices, credit markets, as well as supply chain interruptions, which has contributed to record inflation globally. In addition, the ongoing Russian military actions and the resulting sanctions could continue to adversely affect the global economyprice per share of our common stock, and financial markets and lead to instability and lack of liquidity in capital markets, potentially making it may be more difficult for us to obtain additional funds. We are continuingfinancing. If potential collaborators decline to monitor inflation, the situationdo business with us or potential investors decline to participate in Ukraine and global capital markets and assessing its potential impact on our business.

Although,any future financings due to date, our business has not been materially impacted by the ongoing military conflict between Russian and Ukraine, geopolitical tensions, or record inflation, it is impossible to predict the extent to which our operations will be impacted in the short and long term, or the ways in which such matters may impact our business. The extent and duration of the conflict in Ukraine, geopolitical tensions, record inflation and resulting market disruptions are impossible to predict but could be substantial. Any such disruptions may also magnify the impact of other risks described in our Annual Report on Form 10-K for the year ended December 31, 2021.

Our results of operations and liquidity needs could be materially affected by market fluctuations and general economic conditions.

Our results of operations could be materially affected by economic conditions generally, both in the United States and elsewhere around the world. Concerns over inflation, energy costs, geopolitical issues, and the availability and cost of credit have in the past and may continue to contribute to increase volatility and diminished expectations of the economy and markets going forward. Market upheavals may have an adverse effect on us. In the event of a market downturn, our results of operations could be adversely affected. Our future cost of equity or debt capital and access to the capital markets could be adversely affected, and our stock price could decline. There may be disruption or delay in the performance of our third-party contractors and suppliers. If our contractors, suppliers and partners are unable to satisfy their contractual obligations, our business could suffer.

Our operating activities may be restricted as a result of covenants related to the outstanding indebtedness under our venture loan and security agreement with Horizon and we may be required to repay the outstanding indebtedness in an event of default, which could have a materially adverse effect on our business.

In August 2022, we entered into a Venture Loan and Security Agreement, or the Loan Agreement, for separate term loans of up to an aggregate amount of $35.0 million, with Horizon Technology Finance Corporation, or Horizon, in its capacity as a lender and collateral agent for itself and the other financial institutions that from time to time become parties to the Loan Agreement, collectively referred to as the Lenders, secured by a by a security interest in all of our respective rights, title, interests, claims and demands in, to and under all of our respective properties and other assets, subject to limited exceptions and excluding our intellectual property. The Loan Agreement contains various covenants that limitconcerns, our ability to engage in specified types of transactions. These covenants limitincrease our ability to, among other things, sell, transfer, lease or dispose of certain assets; incur indebtedness; encumber or permit liens on certain assets; make certain investments; make certain restricted payments, including paying dividends on, or repurchasing or making distributions with respect to, our common stock; and enter into certain transactions with affiliates. Our businesscash position may be adversely affected by these restrictions on our ability to operate our business.  A breach of any of the covenants under the Loan Agreement could result in a default. Upon the occurrence of an event of default, the Lenders could elect to declare all amounts outstanding, if any, to be immediately due and payable. If there are any amounts outstandinglimited. The perception that we are unable to repay, the Lenders could proceed against the collateral granted to them to secure such indebtedness.

We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization ofcontinue as a going concern may cause others to choose not to deal with us due to concerns about our Versamune and Infectimune based products.

We expectability to spend substantial amounts to complete the development of, seek regulatory approvals for and commercialize PDS0101. Even withmeet our current cash reserves, we will require substantial additional capital to complete the development and potential commercialization of PDS0101 and the development of other Versamune and Infectimune based products.contractual obligations. If we are unable to raise capitalcontinue as a going concern, you could lose all or find appropriate partnering or licensing collaborations or other nondilutive financing, when needed or on acceptable terms, if at all, we could be forced to delay, reduce or eliminate one or morepart of your investment in our development programs or any future commercialization efforts. In addition, attempting to secure additional financing may divert the time and attention of our management from day-to-day activities and harm our development efforts.Company.

Based upon our current operating plan, we believe that our cash reserves will be sufficient to fund our operating expenses and capital expenditure requirements for at least the next 12 months from the date of this report. Our estimate as to what we will be able to accomplish is based on assumptions that may prove to be inaccurate, and we could exhaust our available capital resources sooner than is currently expected. Because the length of time and activities associated with successful development of PDS0101 is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:


initiation the, progress, timing, costs and results of our planned clinical trials;


the outcome, timing and cost of meeting regulatory requirements established by the FDA and other comparable foreign   regulatory authorities;


the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;


the cost of defending potential intellectual property disputes, including any patent infringement actions brought by third parties against us now or in the future;


the effect of competing technological and market developments;


the cost of establishing sales, marketing and distribution capabilities in regions where we choose to commercialize PDS0101 on our own; and


the initiation, progress, timing and results of the commercialization of PDS0101, if approved, for commercial sale.

Additional funding may not be available on acceptable terms, or at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of PDS0101 or potentially discontinue operations.

Raising additional funds by issuing securities may cause dilution to existing stockholders and raising funds through lending and licensing arrangements may restrict our operations or require us to relinquish proprietary rights.

We expect that significant additional capital will be needed in the future to continue our planned operations. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic alliances and license and development agreements in connection with any collaborations.

In February 2020, we completed an underwritten public offering, in which we sold 10,000,000 shares of common stock at a public offering price of $1.30 per share. The shares sold included 769,230 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price. We received gross proceeds of approximately $13 million and net proceeds of approximately $11.9 million after deducting underwriting discounts and commissions. In July 2020, we filed a shelf registration statement, or the 2020 Shelf Registration Statement, with the SEC, for the issuance of common stock, preferred stock, warrants, rights, debt securities and units, which we refer to collectively as the Shelf Securities, up to an aggregate amount of $100 million. The 2020 Shelf Registration Statement was declared effective on July 31, 2020. The 2020 Registration Statement was terminated upon effectiveness of the 2022 Registration Statement (as discussed below). On August 13, 2020, we sold 6,900,000 shares of our common stock at a public offering price of $2.75 per share pursuant to the 2020 Shelf Registration Statement, which includes 900,000 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $19.0 million and net proceeds of approximately $17.1 million, after deducting underwriting discounts and offering expenses. In June 2021, we completed an underwritten public offering in which we sold 6,088,235 shares of common stock at a public offering price of $8.50 per share pursuant to the 2020 Shelf Registration Statement, which includes 794,117 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $51.7 million and net proceeds of approximately $48.5 million, after deducting underwriting discounts and offering expenses.

In August 2022, we filed a shelf registration statement, or the 2022 Shelf Registration Statement, with the SEC for the issuance of common stock, preferred stock, warrants, rights, debt securities, and units up to an aggregate amount of $150 million, $50 million of which covers the offer, issuance and sale by the Company of its common stock under the Sales Agreement (as discussed below).  The 2022 Shelf Registration Statement was declared effective on September 2, 2022.  In August 2022, we entered into an At Market Issuance Sales Agreement, or the Sales Agreement, with B. Riley Securities, Inc. and BTIG, LLC, each an Agent and collectively the Agents, with respect to an at-the-market offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $50.0 million, or the Placement Shares, through or to the Agents, as sales agents or principals.  Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, the Agents may sell the Placement Shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act of 1933, as amended, including, without limitation, sales made through The Nasdaq Capital Market or on any other existing trading market for our common stock. The Agents will use commercially reasonable efforts to sell the Placement Shares from time to time, based upon our instructions (including any price, time or size limits or other customary parameters or conditions we may impose). We will pay the Agents a commission equal to three percent (3%) of the gross sales proceeds of any Placement Shares sold through the Agents under the Sales Agreement, and also has provided the Agents with customary indemnification and contribution rights. We are not obligated to make any sales of our common stock under the Sales Agreement.  The offering of Placement Shares pursuant to the Sales Agreement will terminate upon the earlier of (i) the sale of all Placement Shares subject to the Sales Agreement or (ii) termination of the Sales Agreement in accordance with its terms. We have not sold any shares of our common stock pursuant to the Sales Agreement.

To the extent that we raise additional capital by issuing equity securities, our existing stockholders’ ownership may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, declaring dividends, creating liens, redeeming our stock or making investments.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or Versamune Products or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, or through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties on acceptable terms, we may be required to delay, limit, reduce or terminate our PDS0101 development or future commercialization efforts or grant rights to develop and market other Versamune and Infectimune products that we would otherwise develop and market.
