About Us

We are a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. Our oncology platform utilizes our non-viral ONCOPREX® Nanoparticle Delivery System. Using this system, plasmids containing tumor suppressor genes, which are deleted early in the development of cancer, are encapsulated within lipid nanoparticles and administered intravenously to the patient to re-express the deleted tumor suppressor genes. Our diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, our technology is believed to work by replenishing and rejuvenating the beta cells that make insulin.

Oncology Platform

Our lead oncology drug candidate, REQORSA® Immunogene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, uses the ONCOPREX Nanoparticle Delivery System to deliver DNA plasmids that express the TUSC2 tumor suppressor gene and is initially being developed in combination with prominent approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis (programmed cell death) in cancer cells, and modulates the immune response against cancer cells. In early studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Our strategy is to develop REQORSA in combination with current approved therapies and we believe REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers. 

Acclaim-1: The Acclaim-1 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2 expansion portion, and a Phase 2 randomized portion. Acclaim-1 uses a combination of REQORSA and AstraZeneca's Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression after treatment with Tagrisso. In October 2023, one of our clinical collaborators presented in a poster presentation at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics the Phase 1 results of the Acclaim-1 study.  The reported results showed no dose limiting toxicities (“DLTs”), established a Phase 2 recommended dose of 0.12 mg/kg (the highest dose level administered in the trial) and provided data showing early efficacy of REQORSA in combination with Tagrisso.  Specifically, it showed of the 12 patients treated with escalating doses of REQORSA and standard doses of Tagrisso, all of whom had progressed on Tagrisso containing regimens, two patients experienced prolonged time to progression, including one with continuing partial response. Additionally, a third patient, at the highest dose, has stable disease, is continuing to receive treatment and thus is a candidate for prolonged time to progression. REQORSA administration was generally well tolerated, which we believe is why there were no DLTs. The administration was associated with a delayed infusion-related reaction of muscle aches, fever and chills in some patients, which we believe is similar to reactions seen with the administration of antibodies routinely used in oncology treatment. This was managed with prophylactic steroids, acetaminophen and diphenhydramine, and symptoms decreased with repeat cycles.  We believe this new mechanism and novel approach targeting lung cancer, which comes with a strong safety profile and early signs of efficacy, is paving new ground in the fight against lung cancer. In May 2023, after completion of the Phase 1 portion of the Acclaim-1 trial, the Safety Review Committee (“SRC”) approved advancement from the Phase 1 dose escalation portion of the trial to the Phase 2 expansion portion of the trial. 

The Phase 2 expansion portion of the trial is expected to enroll approximately 66 patients; half will be patients who received only prior Tagrisso treatment and the other half will be patients who received prior Tagrisso treatment and chemotherapy, in order to determine toxicity profiles of patients with different eligibility criteria, as well as efficacy and other endpoints. There will be an interim analysis following the treatment of 19 patients in each cohort. In preparation for the Phase 2 expansion portion of the trial, we are in the process of adding additional clinical sites. The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment.  We are working towards opening the Phase 2 expansion portion of the trial for enrollment as soon as reasonably practicable and expect this will occur between December 2023 and the end of the first quarter of 2024, subject to the availability of a new batch of REQORSA.

Acclaim-2: The Acclaim-2 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2 expansion portion, and a Phase 2 randomized portion. The Phase 1 dose escalation portion of Acclaim-2 is open for enrollment but currently not treating patients. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.’s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to the Acclaim-2 Safety Review Committee approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. The FDA has granted Fast Track Designation for the Acclaim-2 treatment combination of REQORSA and Keytruda in NSCLC patients who have progressed after Keytruda treatment. We expect enrollment in the dose escalation portion of the study to be completed in the second half of 2024, depending on the timing of the availability of a new batch of REQORSA. The Acclaim-2 study has experienced slower than expected patient enrollment, which we primarily attribute to the large number of clinical trials being conducted that seek to combine an investigational drug with Keytruda in the relapsed setting. 

Acclaim-3: The Acclaim-3 study has two portions - a Phase 1 dose escalation portion and a Phase 2 expansion portion. In November 2022, we filed with the FDA our protocol for our Phase 1/2 Acclaim-3 clinical trial using a combination of REQORSA and Genentech, Inc.’s Tecentriq® as maintenance therapy in patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. We are working towards opening the Phase 1 dose escalation portion of the trial for enrollment as soon as reasonably practicable and expect this will occur between December 2023 and the end of the first quarter of 2024, subject to the availability of a new batch of REQORSA. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In June 2023, the FDA granted Fast Track Designation for the Acclaim-3 treatment combination of REQORSA and Tecentriq as maintenance therapy in patients with ES-SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC.  

We have experienced a delay in the successful production of a new batch of REQORSA in connection with our transition to a lipid nanoparticle (“LNP”) third party contract development and manufacturing organization (“LNP CDMO”) with advanced and automated processes that we believe ultimately will allow us to more efficiently scale our product as we increase production for our trials. We currently estimate that we have enough REQORSA to treat patients receiving REQORSA in our ongoing clinical trials through December 2023. In the event we have not produced another batch of REQORSA by the time we have used our inventory of REQORSA, treatment of patients in our ongoing Acclaim-1 and Acclaim-2 clinical trials and pending enrollment of patients in our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials would be delayed until a new batch of REQORSA is successfully produced.  We expect to produce a new batch of REQORSA between December 2023 and the end of the first quarter of 2024. 

In April 2023, at the 2023 Annual Meeting of the American Association of Cancer Researchers (AACR 2023), we presented data that we believe further validates our ONCOPREX Nanoparticle Delivery System platform. These positive pre-clinical data were reported from our University of Texas MD Anderson Cancer Center ("MD Anderson") collaborators and documented the successful delivery of a second tumor suppressor gene, the NPRL2 tumor suppressor gene. The studies used the ONCOPREX Nanoparticle Delivery System to express the NPRL2 gene in anti-PD1 resistant, metastatic human NSCLCs in humanized mouse models. We believe these studies of NPRL2 provide solid data that the ONCOPREX Nanoparticle Delivery System is a platform that can be used with multiple tumor suppressor genes.

The TUSC2 gene is one of a series of tumor suppressor genes on the short arm of Chromosome 3. The therapeutic use of TUSC2 is covered by our exclusive worldwide licenses from MD Anderson. NPRL2 is another tumor suppressor gene also located on the short arm of Chromosome 3 and we have filed for patent protection for its therapeutic use. We believe that our ONCOPREX Nanoparticle Delivery System may allow for delivery of a number of other cancer-fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer. In August 2022, we entered into a three-year sponsored research agreement with MD Anderson to support further pre-clinical studies of TUSC2 and NPRL2. 

Diabetes Gene Therapy

In diabetes, we have exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, we believe this can be done with a routine endoscopy procedure. Our diabetes product candidates are currently being evaluated and optimized in preclinical animal studies at the University of Pittsburgh. GPX-002 is being developed for the treatment of Type 1 diabetes and GPX-003 is being developed for the treatment of Type 2 diabetes. GPX-002 is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. GPX-003 is believed to work by replenishing and rejuvenating the beta cells that make insulin. We expect to finalize our constructs and request to meet with the FDA before the end of 2023 to obtain their guidance on the toxicology studies that we plan to conduct. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-003 in a non-human primate (“NHP”) model of Type 2 diabetes. The extension includes a revised research plan to encompass our most recent technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023.  In February 2023, our research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The study results showed the treated animals had statistically significant decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline.  In July 2023, we entered into an exclusive license agreement with the University of Pittsburgh related to a gene therapy for both Type 1 and Type 2 diabetes using a MafB promoter to drive expression of the Pdx1 and MafA transcription factors.

Implications of Being an Emerging Growth Company

On April 5, 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Although we are currently an emerging growth company, we have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. We have implemented all new accounting pronouncements that are in effect and may affect our financial statements, and we do not believe that there are any other new accounting pronouncements that have been issued that would have a material impact on our financial position or results of operations.

Notwithstanding the foregoing, subject to certain conditions set forth in the JOBS Act, as an “emerging growth company,” we intend to rely on certain exemptions, including, without limitation, the exemption from the requirements (i) to provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act, and (ii) to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. Our eligibility to qualify as an “emerging growth company” will end on December 31, 2023, the last day of our fiscal year following the fifth anniversary of the date of our initial public offering.

RISK FACTORS

Investing in our securities involves a high degree of risk. Prior to making a decision about investing in our securities offered by this prospectus supplement, you should carefully consider the specific risks described below and contained in our annual report on Form 10-K for the fiscal year ended December 31, 2022 under the heading “Item 1A. Risk Factors,” and our Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2023, and as described or may be described in any subsequent quarterly report on Form 10-Q under the heading “Item 1A. Risk Factors,” as well as other information contained in this prospectus supplement and contained or to be contained in our filings with the SEC and incorporated by reference in this prospectus supplement. For a description of these reports and documents, and information about where you can find them, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” If any of the risks or uncertainties described in our SEC filings or any prospectus supplement or any additional risks and uncertainties actually occur, our business, financial condition and results of operations could be materially and adversely affected. 

Risks Related to this Offering

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We currently intend to use the net proceeds of this offering for working capital and general corporate purposes, which may include capital expenditures, research and development expenditures, manufacturing expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock, as further described in the section of this prospectus supplement entitled “Use of Proceeds”. We will have broad discretion in the application of the net proceeds in the category of other working capital and general corporate purposes and investors will be relying on the judgment of our management regarding the application of the proceeds of this offering.

The precise amount and timing of the application of these proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts, our funding requirements and the availability and costs of other funds. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate.

The failure by our management to apply these funds effectively could harm our business, financial condition and results of operations. Pending their use, we may invest the net proceeds from this offering in short-term, interest-bearing instruments. These investments may not yield a favorable return to our stockholders.

If you purchase our common stock in this offering, you will incur immediate and substantial dilution in the book value of your shares.

The offering price per share in this offering may exceed the net tangible book value per share of our common stock outstanding prior to this offering. Assuming that an aggregate of 129,332,644 shares of our common stock are sold during the term of the sales agreement with Wainwright at a price of $0.1933 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on December 12, 2023, for aggregate gross proceeds of $25.0 million, and after deducting commissions and estimated aggregate offering expenses payable by us, you will experience immediate dilution of approximately $0.02 per share, representing the difference between our as adjusted net tangible book value per share as of September 30, 2023 after giving effect to this offering and the assumed offering price. The exercise of outstanding stock options and warrants may result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.

Resales of our common stock in the public market during this offering by our stockholders may cause the market price of our common stock to fall.

We may issue shares of common stock from time to time in connection with this offering. The issuance from time to time of these new shares of common stock, or our ability to issue new shares of common stock in this offering, could result in resales of shares of our common stock by our current stockholders concerned about the potential dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our common stock.

Sales of a substantial number of shares of our common stock, or the perception that such sales may occur, may adversely impact the price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets, or the perception that such sales may occur, could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock would have on the market price of our common stock.

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

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

We do not intend to pay dividends in the foreseeable future.

We have never paid cash dividends on our common stock. We currently intend to retain our future earnings, if any, to finance the operation and growth of our business and currently do not plan to pay any cash dividends in the foreseeable future.

The actual number of shares we will issue under the sales agreement with Wainwright, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement with Wainwright and compliance with applicable law, we have the discretion to deliver placement notices to Wainwright at any time throughout the term of the sales agreement. The number of shares that are sold by Wainwright after delivering a placement notice will fluctuate based on the market price of the common stock during the sales period and limits we set with Wainwright.

The common stock offered hereby will be sold in “at the market offerings,” and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and quantity of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents that we incorporate by reference, contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Such forward-looking statements include those that express plans, anticipation, intent, contingency, goals, targets or future development and/or otherwise are not statements of historical fact. These statements include, but are not limited to, statements regarding:

These forward-looking statements are based on our current expectations and projections about future events and they are subject to risks and uncertainties known and unknown to us that could cause actual results and developments to differ materially from those expressed or implied in such statements, including the risks described under “Risk Factors” in this prospectus supplement and our Annual Report on Form 10-K for the year ended December 31, 2022 as updated by our subsequent filings under the Exchange Act, each of which is incorporated by reference in this prospectus supplement in their entirety.

In some cases, you can identify forward-looking statements by terminology, such as “expects,” “anticipates,” “intends,” “estimates,” “plans,” “believes,” “seeks,” “may,” “should”, “could” or the negative of such terms or other similar expressions. Accordingly, these statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed in them. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this prospectus supplement.

We may not update these forward-looking statements, even though our situation may change in the future, unless required by law to update and disclose material developments related to previously disclosed information. We qualify all of the information presented in this prospectus supplement, and particularly our forward-looking statements, by these cautionary statements.

USE OF PROCEEDS

We may issue and sell shares of common stock having aggregate sales proceeds of up to $25,000,000 from time to time, before deducting sales agent commissions and expenses. The amount of proceeds from this offering will depend upon the number of shares of our common stock sold and the market price at which they are sold. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement with Wainwright.

We currently intend to use the net proceeds from this offering, if any, for working capital and general corporate purposes, which may include capital expenditures, research and development expenditures, manufacturing expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock.

The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. As a result, our management will have broad discretion regarding the timing and application of the net proceeds from this offering. Pending their ultimate use, we intend to invest the net proceeds in short-term, investment-grade, interest-bearing instruments.

DILUTION

If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the price per share you pay in this offering and the as adjusted net tangible book value per share of common stock immediately after this offering. We calculate net tangible book value per share by dividing our net tangible assets (tangible assets less total liabilities) by the number of shares of our common stock issued and outstanding as of September 30, 2023.

Our net tangible book value at September 30, 2023 was approximately $8.5 million, or $0.14 per share. 

After giving effect to the assumed sale of our common stock during the term of the sales agreement with Wainwright in the aggregate amount of $25,000,000 in this offering at an assumed offering price of $0.1933 per share, the last reported sale price of our common stock on the Nasdaq Capital Market on December 12, 2023 and after deducting the commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2023, would have been approximately $32.6 million, or approximately $0.17 per share of our common stock. This represents an immediate increase in net tangible book value of $0.03 per share to our existing stockholders and an immediate dilution of approximately $0.02 per share to new investors participating in this offering, as illustrated by the following table:

The as adjusted information is illustrative only and will adjust based on the actual price to the public, the actual number of shares sold and other terms of the offering determined at the time common stock is sold pursuant to this prospectus supplement. The as adjusted information assumes that all of our common stock in the aggregate amount of $25,000,000 is sold at the assumed offering price of $0.1933 per share, the last reported sale price of our Common Stock on the Nasdaq Capital Market on December 12, 2023. The shares sold in this offering, if any, will be sold from time to time at various prices.

The number of shares of common stock to be outstanding after the offering is based on 59,429,822 shares outstanding as of September 30, 2023 and excludes, as of that date, the following: 

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Wainwright, pursuant to which we may issue and sell from time to time shares of our common stock having an aggregate offering price of not more than $25,000,000 through Wainwright as our sales agent. Sales of the common stock, if any, will be made by any method permitted that is deemed an “at the market” offering as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or the Securities Act, including sales made directly on or through the Nasdaq Capital Market or any other existing trading market in the United States for our common stock, sales made to or through a market maker other than on an exchange or otherwise, directly to Wainwright as principal, in negotiated transactions at market prices prevailing at the time of sale or at prices related to such prevailing market prices and/or in any other method permitted by law.

We will designate the number of shares which we desire to sell, the time period during which sales are requested to be made, any limitation on the number of shares that may be sold in one day and any minimum price below which sales may not be made. Subject to the terms and conditions of the sales agreement, Wainwright will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell on our behalf all of the shares of common stock requested to be sold by us. We or Wainwright may suspend the offering of the common stock being made through Wainwright under the sales agreement upon proper notice to the other party.

Settlement for sales of common stock will occur on the second business day or such shorter settlement cycle as may be in effect under Exchange Act Rule 15c6-1 from time to time, following the date on which any sales are made, or on some other date that is agreed upon by us and Wainwright in connection with a particular transaction, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus supplement and the accompanying prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and Wainwright may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Wainwright in cash, upon each sale of our shares of common stock pursuant to the sales agreement, a commission of 3.0% of the gross proceeds from each sale of shares of our common stock. Because there is no minimum offering amount required as a condition to this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. Pursuant to the terms of the sales agreement, we agreed to reimburse Wainwright for the reasonable fees and expenses of its legal counsel incurred in connection with entering into the transactions contemplated by the sales agreement in an amount not to exceed $50,000 in the aggregate, in addition to up to $2,500 per due diligence update session for Wainwright’s counsel’s fees. We will report at least quarterly the number of shares of common stock sold through Wainwright under the sales agreement, the net proceeds to us and the compensation paid by us to Wainwright in connection with the sales of common stock.

In connection with the sales of common stock on our behalf, Wainwright will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Wainwright will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Wainwright against certain liabilities, including liabilities under the Securities Act.

The offering of our shares of common stock pursuant to the sales agreement will terminate upon the earlier of the sale of all of our shares of common stock provided for in this prospectus supplement or termination of the sales agreement as permitted therein.

To the extent required by Regulation M, Wainwright will not engage in any market making activities involving our shares of common stock while the offering is ongoing under this prospectus supplement.

Wainwright and its affiliates may in the future provide various investment banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees.

This prospectus supplement and the accompanying prospectus may be made available in electronic format on a website maintained by Wainwright, and Wainwright may distribute this prospectus and the accompanying prospectus electronically. A copy of the sales agreement is filed with the SEC as an exhibit to our Current Report on Form 8-K filed with the SEC on December 13, 2023.

PROSPECTUS SUMMARY

The following summary highlights some information from this prospectus. It is not complete and does not contain all of the information that you should consider before making an investment decision. You should read this entire prospectus, including the “Risk Factors” section on page 5 and the disclosures to which that section refers you, the financial statements and related notes and the other more detailed information appearing elsewhere or incorporated by reference into this prospectus before investing in any of the securities described in this prospectus.

About Us

We are a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. Our oncology platform utilizes our non-viral ONCOPREX® Nanoparticle Delivery System. Using this system, plasmids containing tumor suppressor genes, which are deleted early in the development of cancer, are encapsulated within lipid nanoparticles and administered intravenously to the patient to re-express the deleted tumor suppressor genes. Our diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but are distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, our technology is believed to work by replenishing and rejuvenating the beta cells that make insulin.

Oncology Platform

Our lead oncology drug candidate, REQORSA® Immunogene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with top selling cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). The active agent in REQORSA is a plasmid that expresses a tumor suppressor gene named TUSC2. REQORSA has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and modulates the immune response against cancer cells. REQORSA has been shown to be complementary with targeted drugs and immunotherapies. We believe REQORSA’s unique attributes position REQORSA to provide treatment for patients with NSCLC, SCLC, and possibly other cancers, and that it can improve on current therapies.

Acclaim – 1: We currently are enrolling and treating patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca PLC’s Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression after treatment with Tagrisso. In August 2022, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved escalating the dose from 0.06 mg/kg in the first cohort of patients to 0.09 mg/kg in the second cohort of patients and in December 2022, the SRC approved escalating the dose from 0.09 mg/kg in the second cohort to 0.12 mg/kg in the third and final cohort. We are thus enrolling and treating patients at the 0.12 mg/kg dose level. We expect enrollment in the dose escalation portion of the study to be completed within the several days following the March 31, 2023 filing of the Company's Annual Report. Once the dose escalation portion of the study is complete and the maximum tolerated dose ("MTD") or recommended Phase 2 dose ("RP2D") is established, we will proceed into the dose expansion portion of the study. The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment.

Acclaim – 2: We currently are enrolling and treating patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-2 clinical trial. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.’s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are currently being treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to the Acclaim-2 Safety Review Committee ("Acclaim-2 SRC") approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. We expect enrollment in the dose escalation portion of the study to be completed by the end of 2023. We will then evaluate patients in the dose expansion portion of the study at the MTD or RP2D. The FDA has granted Fast Track Designation for the Acclaim-2 treatment combination of REQORSA and Keytruda in NSCLC patients who have progressed after Keytruda treatment.

The dose expansion portion of Acclaim-2 is a Phase 2 study and the dose expansion portion of Acclaim-1 will be considered a Phase 2 study upon the filing with the FDA of an upcoming protocol amendment. The dose expansion provides us the advantage of early insight into drug effectiveness in defined and distinct patient populations at the MTD or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the dose expansion portion of each study.

Acclaim – 3: In November 2022, we filed with the FDA our protocol for our Phase 1/2 Acclaim-3 clinical trial using a combination of REQORSA and Genentech, Inc.’s Tecentriq® as maintenance therapy in patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. We expect to dose the first patient in Acclaim-3 by the end of the third quarter of 2023. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced.

The TUSC2 gene is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by our exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center ("MD Anderson"). We believe that our ONCOPREX Nanoparticle Delivery System allows for delivery of a number of cancer-fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and are in early stages of discovery programs to identify early-stage candidates. In August 2022, we entered into a sponsored research agreement with MD Anderson to support further pre-clinical studies of TUSC2 and other tumor suppressor genes.

Diabetes Gene Therapy

In diabetes, we have exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. Our diabetes product candidates are currently being evaluated in preclinical studies at the University of Pittsburgh. GPX-002 is being developed for the treatment of Type 1 diabetes and GPX-003 is being developed for the treatment of Type 2 diabetes. GPX-002 is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but are distinct enough from beta cells to evade the body’s immune system. GPX-003 is believed to work by replenishing and rejuvenating the beta cells that make insulin. In August 2022, we entered into a one-year sponsored research agreement with the University of Pittsburgh for the use of GPX-003 in a non-human primate (“NHP”) model in Type 2 diabetes and we expect data from this study to be reported by the end of 2023. In February 2023, the Company’s research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company” as the term is used in The Jumpstart Our Business Startups Act of 2012 ("JOBS Act"), and therefore, we may take advantage of certain exemptions from various public company reporting requirements, including:

●         a requirement to only have two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis;

●         exemption from the auditor attestation requirement on the effectiveness of our internal controls over financial reporting;

●         reduced disclosure obligations regarding executive compensation; and

●         exemptions from the requirements of holding a nonbinding advisory stockholder vote on executive compensation and any golden parachute payments.

We expect that our eligibility to qualify as an “emerging growth company” will end on December 31, 2023, the last day of our fiscal year following the fifth anniversary of the date of our initial public offering. For so long as we remain an emerging growth company, we may choose to take advantage of some, but not all, of the available benefits of the JOBS Act. We have taken advantage of some of the reduced reporting requirements in our filings with the SEC, including our most recent Annual Report on Form 10-K and the other documents incorporated by reference into this prospectus. Accordingly, the information contained or incorporated by reference herein may be different than the information you receive from other public companies in which you hold stock. In addition, the JOBS Act provides that an emerging growth company can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

USE OF PROCEEDS

Unless we inform you otherwise in the prospectus supplement relating to a particular offering of securities, we will use the net proceeds from the sale of the securities offered by this prospectus and the exercise price from the exercise of any convertible securities, if any, for working capital and general corporate purposes, which could include, without limitation, application towards purposes and uses such as capital expenditures, research and development expenditures, regulatory affairs expenditures, clinical trial expenditures, acquisitions of new technologies and investments, business combinations and the repayment, refinancing, redemption or repurchase of indebtedness or capital stock.

When particular securities are offered, the prospectus supplement relating to that offering will set forth our intended use of the net proceeds received from the sale of those securities we sell.

THE SECURITIES WE MAY OFFER

General

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all of the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. If we indicate in the applicable prospectus supplement, the terms of the securities may differ from the terms we have summarized below. We may also include in the prospectus supplement information about material United States federal income tax considerations relating to the securities, and the securities exchange, if any, on which the securities will be listed.

We may sell from time to time, in one or more offerings:

In this prospectus, we refer to the common stock, preferred stock, debt securities, subscription rights, warrants and units collectively as “securities.” The total dollar amount of all securities that we may sell will not exceed $200,000,000.

If we issue debt securities at a discount from their original stated principal amount, then, for purposes of calculating the total dollar amount of all securities issued under this prospectus, we will treat the initial offering price of the debt securities as the total original principal amount of the debt securities.

This prospectus may not be used to consummate a sale of securities unless it is accompanied by a prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of:

As of close of business on March 15, 2023, 51,974,078 shares of our common stock were issued and outstanding and no shares of our preferred stock were issued and outstanding.

The additional shares of our authorized capital stock available for issuance may be issued at times and under circumstances so as to have a dilutive effect on earnings per share and on the equity ownership of the holders of our common stock. The ability of our board of directors to issue additional shares of stock could enhance the board’s ability to negotiate on behalf of the stockholders in a takeover situation but could also be used by the board to make a change-in-control more difficult, thereby denying stockholders the potential to sell their shares at a premium and entrenching current management. The following description is a summary of the material provisions of our capital stock. You should refer to our amended and restated certificate of incorporation and bylaws, both of which are on file with the SEC as exhibits to previous SEC filings, for additional information. The summary below is qualified by provisions of applicable law.

Holders of the Company’s Common Stock are entitled, subject to the rights, privileges, restrictions and conditions attaching to any other class of shares ranking in priority to the Common Stock, to receive any dividend declared by the Company’s board of directors out of the Company’s assets which are legally available. Such dividends may be paid in cash, in property, or in shares of the Company’s capital stock, subject to the provisions of the Certificate of Incorporation and applicable law.

The Company has never declared or paid cash dividends on its capital stock.  The Company currently intends to retain all available funds and any future earnings for use in the operation of its business and does not anticipate paying any dividends on the Company's Common Stock in the foreseeable future.  Any future determination to declare dividends will be made at the discretion of the Company's board of directors and will depend on, among other factors, the Company's financial condition, operating results, capital requirements, contractual restrictions, general business conditions and other factors that the Company's board of directors may deem relevant.

The Company’s Charter Documents provide that, except as otherwise required by law, and subject to the rights of the holders of any series of Preferred Stock, all vacancies, and any newly created directorships, unless the Board of Directors determines that any such vacancies or newly created directorships shall be filled by the stockholders, shall,  be filled only by the affirmative vote of a majority of directors then in office, even if less than a quorum. Further, the Company’s directors may only be removed with cause and by the affirmative vote of the holders of at least 66-2/3% of the voting power of all of the Company’s then outstanding capital stock. In addition, pursuant to the Company’s Certificate of Incorporation, the number of directors constituting the Company’s board of directors may be changed only by resolution of the Company’s board of directors.

Limits on Ability of Stockholders to Act by Written Consent or Call a Special Meeting 

The Company’s Charter Documents require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent. In addition, pursuant to the Company’s Bylaws, special meetings of the Company’s stockholders may be called only by the chairman of the board, the Company’s Chief Executive Officer or by the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors.

Stockholder Proposals

The Company’s Bylaws provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and also specify requirements as to the form and content of a stockholder’s notice.  These advance notice procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of our company.

Staggered Board

The Company’s Charter Documents provide that the Company’s board of directors shall be divided into three classes and that directors shall be elected for a term of three years.  Our classified board of directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us because it generally makes it more difficult for stockholders to replace a majority of the directors.

Issuance of Undesignated Preferred Stock

As discussed above, our board of directors has the ability to designate and issue preferred stock with voting or other rights or preferences that could deter hostile takeovers or delay changes in our control or management.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our Charter Documents do not expressly provide for cumulative voting. Without cumulative voting, a minority stockholder may not be able to gain as many seats on our board of directors as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our board of directors to influence our board of directors’ decision regarding a takeover.

Exclusive Forum

The Company’s Charter Documents provide that unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Company, (ii)  any action asserting a claim for breach of any fiduciary duty owed by any director, officer, or other employee of the Company to the Company or the Company’s stockholders, (iii) any action  asserting a claim against the Company or any director or officer or other employee of the Company arising pursuant to any provision of the DGCL or the Company’s Certificate of Incorporation or Bylaws or (iv) any action asserting a claim against the Company or any of the Company’s directors, officers or other employees governed by the internal affairs doctrine. This exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

Transfer Agent and Registrar

The Company’s transfer agent and registrar is VStock Transfer, LLC whose address is 18 Lafayette Place, Woodmere, New York 11598.

Listing

The Company’s Common Stock is listed on The Nasdaq Capital Market under the symbol “GNPX.”

Description of Preferred Stock

We are authorized to issue up to 10,000,000 shares of preferred stock, all of which are undesignated. Our board of directors has the authority, within the limitations and restrictions prescribed by law and without stockholder approval, to provide by resolution for the issuance of shares of preferred stock, and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference and the number of shares constituting any series of the designation of such series, by delivering an appropriate certificate of amendment to our amended and restated certificate of incorporation to the Delaware Secretary of State pursuant to the Delaware General Corporation Law, or the DGCL. The issuance of preferred stock could have the effect of decreasing the market price of the common stock, impeding or delaying a possible takeover and adversely affecting the voting and other rights of the holders of our common stock.

Transfer Agent and Registrar for Preferred Stock

The transfer agent and registrar for any series or class of preferred stock will be set forth in each applicable prospectus supplement.

DESCRIPTION OF STOCK WARRANTS

We summarize below some of the provisions that will apply to the warrants unless the applicable prospectus supplement provides otherwise. This summary may not contain all information that is important to you. The complete terms of the warrants will be contained in the applicable warrant certificate and warrant agreement. These documents have been or will be included or incorporated by reference as exhibits to the registration statement of which this prospectus is a part. You should read the warrant certificate and the warrant agreement. You should also read the prospectus supplement, which will contain additional information and which may update or change some of the information below.

General

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank, trust company or other financial institution, as warrant agent, or we may issue warrants directly to investors. A description of the terms and material provisions of any warrants we may issue will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will describe the following terms of any warrants in respect of which this prospectus is being delivered:

Transfer Agent and Registrar

The transfer agent and registrar, if any, for any warrants will be set forth in the applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

This prospectus describes certain general terms and provisions of debt securities that we may offer. The debt securities may be issued pursuant to, in the case of senior debt securities, a senior indenture, and in the case of subordinated debt securities, a subordinated indenture, in each case in the forms filed as exhibits to this registration statement, which we refer to as the “indentures.” The indentures will be entered into between us and a trustee to be named prior to the issuance of any debt securities, which we refer to as the “trustee.” The indentures will not limit the amount of debt securities that can be issued thereunder and will provide that the debt securities may be issued from time to time in one or more series pursuant to the terms of one or more securities resolutions or supplemental indentures creating such series.

We have summarized below the material provisions of the indentures and the debt securities or indicated which material provisions will be described in the related prospectus supplement for any offering of debt securities. These descriptions are only summaries, and you should refer to the relevant indenture for the particular offering of debt securities itself which will describe completely the terms and definitions of the offered debt securities and contain additional information about the debt securities.

Terms

When we offer to sell a particular series of debt securities, we will describe the specific terms of the securities in a prospectus supplement. The prospectus supplement will set forth the following terms, as applicable, of the debt securities offered thereby:

Debt securities of any series may be issued as registered debt securities or uncertificated debt securities, in such denominations as specified in the terms of the series.

Securities may be issued under the indentures as Discounted Debt Securities to be offered and sold at a substantial discount from the principal amount thereof. Special United States federal income tax and other considerations applicable thereto will be described in the prospectus supplement relating to such Discounted Debt Securities. “Discounted Debt Security” means a security where the amount of principal due upon acceleration is less than the stated principal amount.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance and the offering price, and will be consolidated with, and form a single series with, such outstanding debt securities.

Ranking

The senior debt securities will rank equally with all of our other senior and unsubordinated debt. Our secured debt, if any, will be effectively senior to the senior debt securities to the extent of the value of the assets securing such debt. The subordinated debt securities will be subordinate and junior in right of payment to all of our present and future senior indebtedness to the extent and in the manner described in the prospectus supplement and as set forth in the board resolution, officer’s certificate or supplemental indenture relating to such offering.

We have only a stockholder’s claim on the assets of our subsidiaries. This stockholder’s claim is junior to the claims that creditors of our subsidiaries have against our subsidiaries. Holders of our debt securities will be our creditors and not creditors of any of our subsidiaries. As a result, all the existing and future liabilities of our subsidiaries, including any claims of their creditors, will effectively be senior to the debt securities with respect to the assets of our subsidiaries. In addition, to the extent that we issue any secured debt, the debt securities will be effectively subordinated to such secured debt to the extent of the value of the assets securing such secured debt.

The debt securities will be obligations exclusively of Genprex, Inc. To the extent that our ability to service our debt, including the debt securities, may be dependent upon the earnings of our subsidiaries, our ability to do so will be dependent on the ability of our subsidiaries to distribute those earnings to us as dividends, loans or other payments.

Certain Covenants

Any covenants that may apply to a particular series of debt securities will be described in the prospectus supplement relating thereto.

Successor Obligor

The indentures provide that, unless otherwise specified in the securities resolution or supplemental indenture establishing a series of debt securities, we shall not consolidate with or merge into, or transfer all or substantially all of our assets to, any person in any transaction in which we are not the survivor, unless:

In such event, the successor will be substituted for us, and thereafter all of our obligations under the relevant indenture, the debt securities and any coupons will terminate.

The indentures provide that these limitations shall not apply if our board of directors makes a good faith determination that the principal purpose of the transaction is to change our state of incorporation.

Exchange of Debt Securities

Registered debt securities may be exchanged for an equal aggregate principal amount of registered debt securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the registered debt securities at an agency of the Company maintained for such purpose and upon fulfillment of all other requirements of such agent.

Default and Remedies

Unless the securities resolution or supplemental indenture establishing the series otherwise provides (in which event the prospectus supplement will so state), an “Event of Default” with respect to a series of debt securities will occur if:

The term “Bankruptcy Law” means Title 11 of the United States Code or any similar Federal or State law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or a similar official under any Bankruptcy Law.

“Default” means any event which is, or after notice or passage of time would be, an Event of Default. A Default under subparagraph (3) above is not an Event of Default until the trustee or the holders of at least 25% in principal amount of the series notify us of the Default and we do not cure the Default within the time specified after receipt of the notice.

The trustee may require indemnity satisfactory to it before it enforces the indentures or the debt securities of the series. Subject to certain limitations, holders of a majority in principal amount of the debt securities of the series may direct the trustee in its exercise of any trust or power with respect to such series. Except in the case of Default in payment on a series, the trustee may withhold from securityholders of such series notice of any continuing Default if the trustee determines that withholding notice is in the interest of such securityholders. We are required to furnish the trustee annually a brief certificate as to our compliance with all conditions and covenants under the indentures.

The indentures do not have cross-default provisions. Thus, a default by us on any other debt, including any other series of debt securities, would not constitute an Event of Default.

Amendments and Waivers

The indentures and the debt securities or any coupons of the series may be amended, and any Default may be waived as follows:

Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), the debt securities and the indentures may be amended with the consent of the holders of a majority in principal amount of the debt securities of all series affected voting as one class. Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), a Default other than a Default in payment on a particular series may be waived with the consent of the holders of a majority in principal amount of the debt securities of the series. However, without the consent of each securityholder affected, no amendment or waiver may:

Without the consent of any securityholder, the indentures or the debt securities may be amended to:

Conversion Rights

Any securities resolution or supplemental indenture establishing a series of debt securities may provide that the debt securities of such series will be convertible at the option of the holders thereof into or for our common stock or other equity or debt instruments. The securities resolution or supplemental indenture may establish, among other things, (1) the number or amount of shares of common stock or other equity or debt instruments for which $1,000 aggregate principal amount of the debt securities of the series is convertible, as may be adjusted pursuant to the terms of the relevant indenture and the securities resolution; and (2) provisions for adjustments to the conversion rate and limitations upon exercise of the conversion right. The indentures provide that we will not be required to make an adjustment in the conversion rate unless the adjustment would require a cumulative change of at least 1% in the conversion rate. However, we will carry forward any adjustments that are less than 1% of the conversion rate and take them into account in any subsequent adjustment of the conversion rate.

Legal Defeasance and Covenant Defeasance

Debt securities of a series may be defeased in accordance with their terms and, unless the securities resolution or supplemental indenture establishing the terms of the series otherwise provides, as set forth below. We at any time may terminate as to a series all of our obligations (except for certain obligations, including obligations with respect to the defeasance trust and obligations to register the transfer or exchange of a debt security, to replace destroyed, lost or stolen debt securities and coupons and to maintain paying agencies in respect of the debt securities) with respect to the debt securities of the series and any related coupons and the relevant indenture, which we refer to as legal defeasance. We at any time may terminate as to a series our obligations with respect to any restrictive covenants which may be applicable to a particular series, which we refer to as covenant defeasance.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, a series may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option, a series may not be accelerated by reference to any covenant which may be applicable to a series.

To exercise either defeasance option as to a series, we must (1) irrevocably deposit in trust with the trustee (or another trustee) money or U.S. Government Obligations (as defined below), deliver a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due on the deposited U.S. Government Obligations, without reinvestment, plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal and interest when due on all debt securities of such series to maturity or redemption, as the case may be; and (2) comply with certain other conditions. In particular, we must obtain an opinion of tax counsel that the defeasance will not result in recognition of any gain or loss to holders for federal income tax purposes.

“U.S. Government Obligations” means direct obligations of the United States or any agency or instrumentality of the United States, the payment of which is unconditionally guaranteed by the United States, which, in either case, have the full faith and credit of the United States pledged for payment and which are not callable at the issuer’s option, or certificates representing an ownership interest in such obligations.

Regarding the Trustee

Unless otherwise indicated in a prospectus supplement, the trustee will also act as depository of funds, transfer agent, paying agent and conversion agent, as applicable, with respect to the debt securities. In certain circumstances, we or the securityholders may remove the trustee as the trustee under a given indenture. The indenture trustee may also provide additional unrelated services to us as a depository of funds, registrar, trustee and similar services.

Governing Law

The indentures and the debt securities will be governed by New York law, except to the extent that the Trust Indenture Act of 1939 is applicable.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our equity or debt securities. These subscription rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security (but, to the extent convertible securities are included in the units, the holder of the units will be deemed the holder of the convertible securities and not the holder of the underlying securities). The unit agreement under which a unit is issued, if any, may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. The applicable prospectus supplement may describe:

This summary of certain general terms of units and any summary description of units in the applicable prospectus supplement do not purport to be complete and are qualified in their entirety by reference to all provisions of the applicable unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. The forms of the unit agreements and other documents relating to a particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you.

FORMS OF SECURITIES

Each debt security and, to the extent applicable, warrant, subscription right and unit, will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities. We may issue the registered debt securities and, to the extent applicable, warrants, subscription rights and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities and any payments to holders with respect to warrants represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of the Company, the trustees, the warrant agents or any other agent of the Company, agent of the trustees or agent of the warrant will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or warrant agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

Initial Offering and Sale of Securities

Unless otherwise set forth in a prospectus supplement accompanying this prospectus, we may sell the securities being offered hereby, from time to time, by one or more of the following methods:

Offerings of securities covered by this prospectus also may be made into an existing trading market for those securities in transactions at other than a fixed price, either:

Those at-the-market offerings, if any, will be conducted by underwriters acting as principal or agent of the Company, who may also be third-party sellers of securities as described above. The prospectus supplement with respect to the offered securities will set forth the terms of the offering of the offered securities, including:

The distribution of the securities may be effected from time to time in one or more transactions:

Each prospectus supplement will set forth the manner and terms of an offering of securities including:

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The applicable prospectus supplement may indicate, in connection with such a transaction, that the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities pledged by us or borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

Sales Through Underwriters

If underwriters are used in the sale of some or all of the securities covered by this prospectus, the underwriters will acquire the securities for their own account. The underwriters may resell the securities, either directly to the public or to securities dealers, at various times in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to certain conditions. Unless indicated otherwise in a prospectus supplement, the underwriters will be obligated to purchase all the securities of the series offered if any of the securities are purchased.

Any public offering price and any concessions allowed or reallowed to dealers may be changed intermittently.

Sales Through Agents

Unless otherwise indicated in the applicable prospectus supplement, when securities are sold through an agent, the designated agent will agree, for the period of its appointment as agent, to use specified efforts to sell the securities for our account and will receive commissions from us as will be set forth in the applicable prospectus supplement.

Securities bought in accordance with a redemption or repayment under their terms also may be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing by one or more firms acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the prospectus supplement. Remarketing firms may be deemed to be underwriters in connection with the securities remarketed by them.

If so indicated in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers by certain specified institutions to purchase securities at a price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a future date specified in the prospectus supplement. These contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of these contracts.

Direct Sales

We may also sell offered securities directly to institutional investors or others. In this case, no underwriters or agents would be involved. The terms of such sales will be described in the applicable prospectus supplement.

General Information

Broker-dealers, agents or underwriters may receive compensation in the form of discounts, concessions or commissions from us and/or the purchasers of securities for whom such broker-dealers, agents or underwriters may act as agents or to whom they sell as principal, or both. This compensation to a particular broker-dealer might be in excess of customary commissions.

Underwriters, dealers and agents that participate in any distribution of the offered securities may be deemed “underwriters” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), so any discounts or commissions they receive in connection with the distribution may be deemed to be underwriting compensation. Those underwriters and agents may be entitled, under their agreements with us, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution by us to payments that they may be required to make in respect of those civil liabilities. Certain of those underwriters or agents may be customers of, engage in transactions with, or perform services for, us or our affiliates in the ordinary course of business. We will identify any underwriters or agents, and describe their compensation, in a prospectus supplement. Any institutional investors or others that purchase offered securities directly, and then resell the securities, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act.

We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, if we enter into any material arrangement with a broker, dealer, agent or underwriter for the sale of securities through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. Such prospectus supplement will disclose:

In order to facilitate the offering of certain securities under this prospectus or an applicable prospectus supplement, certain persons participating in the offering of those securities may engage in transactions that stabilize, maintain or otherwise affect the price of those securities during and after the offering of those securities. Specifically, if the applicable prospectus supplement permits, the underwriters of those securities may over-allot or otherwise create a short position in those securities for their own account by selling more of those securities than have been sold to them by us and may elect to cover any such short position by purchasing those securities in the open market.

In addition, the underwriters may stabilize or maintain the price of those securities by bidding for or purchasing those securities in the open market and may impose penalty bids, under which selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of securities to the extent that it discourages resales of the securities. No representation is made as to the magnitude or effect of any such stabilization or other transactions. Such transactions, if commenced, may be discontinued at any time.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under Rule 15c6-1 of the Exchange Act, unless the parties to any such trade expressly agree otherwise. trades in the secondary market generally are required to settle (a) in two business days, prior to May 28, 2024 and (b) in one business day starting on May 28, 2024. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day (prior to May 28, 2024) or second business day (on or after May 28, 2024) before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

This prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format may be made available on the Internet sites of, or through other online services maintained by, us and/or one or more of the agents and/or dealers participating in an offering of securities, or by their affiliates. In those cases, prospective investors may be able to view offering terms online and, depending upon the particular agent or dealer, prospective investors may be allowed to place orders online.

Other than this prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format, the information on our website or the website of any agent or dealer, and any information contained in any other website maintained by any agent or dealer:

There can be no assurance that we will sell all or any of the securities offered by this prospectus.

This prospectus may also be used in connection with any issuance of common stock or preferred stock upon exercise of a warrant if such issuance is not exempt from the registration requirements of the Securities Act.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above.

ADDITIONAL INFORMATION

We have filed with the SEC a registration statement on Form S-3 under the Securities Act with respect to the securities offered by this prospectus. This prospectus, which is part of the registration statement, omits certain information, exhibits, schedules and undertakings set forth in the registration statement. For further information pertaining to us and our securities, reference is made to our SEC filings and the registration statement and the exhibits and schedules to the registration statement. Statements contained in this prospectus as to the contents or provisions of any documents referred to in this prospectus are not necessarily complete, and in each instance where a copy of the document has been filed as an exhibit to the registration statement, reference is made to the exhibit for a more complete description of the matters involved.

In addition, registration statements and certain other filings made with the SEC electronically are publicly available through the SEC’s web site at http://www.sec.gov. The registration statement, including all exhibits and amendments to the registration statement, has been filed electronically with the SEC.

We are subject to the information and periodic reporting requirements of the Securities Exchange Act of 1934, as amended, and, in accordance with such requirements, will file periodic reports, proxy statements, and other information with the SEC. These periodic reports, proxy statements, and other information will be available for inspection and copying at the web site of the SEC referred to above. We also maintain a website at www.genprex.com, at which you may access these materials free of charge as soon as reasonably practicable after they are electronically filed with, or furnished to, the SEC. The information contained in, or that can be accessed through, our website is not part of, and is not incorporated into, this prospectus. We have included our website address in this prospectus solely as an inactive textual reference.

You should rely only on the information in this prospectus and the additional information described above and under the heading “Incorporation of Certain Information by Reference” below. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely upon it. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information in this prospectus was accurate on the date of the front cover of this prospectus only. Our business, financial condition, results of operations and prospects may have changed since that date.

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

The SEC allows us to “incorporate by reference” information that we file with it into this prospectus, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is an important part of this prospectus. The information incorporated by reference is considered to be a part of this prospectus, and information that we file later with the SEC will automatically update and supersede information contained in this prospectus and any accompanying prospectus supplement.

We incorporate by reference the documents listed below that we have previously filed with the SEC:

All reports and other documents that we file with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this prospectus but prior to the termination of the offering of the securities hereunder will also be considered to be incorporated by reference into this prospectus from the date of the filing of these reports and documents, and will supersede the information herein; provided, however, that all reports, exhibits and other information that we “furnish” to the SEC will not be considered incorporated by reference into this prospectus. Any statement contained in a document incorporated by reference in this prospectus or any prospectus supplement shall be deemed to be modified or superseded to the extent that a statement contained herein, therein or in any other subsequently filed document that also is incorporated by reference herein or therein modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this prospectus or any prospectus supplement.

We will provide you without charge, upon your oral or written request, with a copy of any or all reports, proxy statements and other documents we file with the SEC, as well as any or all of the documents incorporated by reference in this prospectus or the registration statement (other than exhibits to such documents unless such exhibits are specifically incorporated by reference into such documents).
