[10-Q] Imunon, Inc. Quarterly Earnings Report
Imunon, Inc. reported a Q1 2026 net loss of $4.25M, slightly wider than the prior-year loss of $4.10M, as operating expenses rose to $4.31M driven mainly by higher research and development spending.
Cash and cash equivalents declined to $4.79M at March 31, 2026 from $8.78M at year-end, with $3.99M used in operating activities in the quarter. Management concludes there is substantial doubt about Imunon’s ability to continue as a going concern without new capital.
The company remains a clinical-stage biotech focused on its DNA-based immunotherapy IMNN-001 for advanced ovarian cancer. Final Phase 2 OVATION 2 data showed a 14.7‑month improvement in median overall survival versus standard chemotherapy alone, and a 24.2‑month gain in patients also receiving PARP inhibitors, supporting advancement into a Phase 3 pivotal trial.
Positive
- None.
Negative
- None.
Insights
Strong ovarian cancer data contrast with acute funding and going concern risk.
Imunon delivered impressive final Phase 2 OVATION 2 results: median overall survival improved by 14.7 months (45.1 vs. 30.4) versus standard chemotherapy, and by 24.2 months (65.6 vs. 41.4) in patients also on PARP inhibitors. These outcomes underpin the ongoing Phase 3 OVATION 3 trial and support the scientific rationale for IMNN-001.
Financially, the picture is strained. Q1 2026 net loss was $4.25M, with $3.99M of operating cash burn and only $4.79M of cash on hand at March 31, 2026. Cumulative losses are about $426M. Management explicitly states there is substantial doubt about the company’s ability to continue as a going concern without new financing.
The company has an effective shelf registration and expanded at-the-market capacity, and previously raised $7.0M in a December 2025 offering. However, future access to capital will depend on market conditions and investor appetite. Until additional funding is secured, the going concern uncertainty and low cash relative to burn are central risks, even as clinical data strengthen the therapeutic case for IMNN-001.

Cautionary Note Regarding Forward-Looking Statements
This report includes “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”). All statements other than statements of historical fact are “forward-looking statements” for purposes of this Quarterly Report on Form 10-Q, including, without limitation, any projections of earnings, revenue or other financial items, any statements of the plans and objectives of management for future operations (including, but not limited to, pre-clinical development, clinical trials, manufacturing and commercialization), uncertainties and assumptions regarding any continuing impact of the COVID-19 pandemic on our business, operations, clinical trials, supply chain, strategy, goals and anticipated timelines, any statements concerning proposed drug candidates, potential therapeutic benefits, or other new products or services, any statements regarding future economic conditions or performance, any changes in the course of research and development activities and in clinical trials, any possible changes in cost and timing of development and testing, capital structure, financial condition, working capital needs and other financial items, and any statements of assumptions underlying any of the foregoing. In some cases, forward-looking statements can be identified using terminology such as “may,” “will,” “expects,” “plans,” “anticipates,” “estimates,” “potential” or “continue,” or the negative thereof or other comparable terminology. Although we believe that our expectations are based on reasonable assumptions within the bounds of our knowledge of our industry, business, and operations, we cannot guarantee that actual results will not differ materially from our expectations.
Our future financial condition and results of operations, as well as any forward-looking statements, are subject to inherent risks and uncertainties, including, but not limited to, the inherent uncertainty in the drug development process, our ability to raise additional capital to fund our planned future operations, our ability to obtain or maintain U.S. Food and Drug Administration (“FDA”) and foreign regulatory approvals for our drug candidates, our ability to enroll patients in our clinical trials, risks relating to third parties’ conduct of our clinical trials, risks relating to government, private health insurers and other third-party payers coverage or reimbursement, risks relating to commercial potential of a drug candidate in development, changes in technologies for the treatment of cancer, impact of development of competitive drug candidates by others, risks relating to intellectual property, volatility in the market price of our common stock, potential inability to maintain compliance with The Nasdaq Marketplace Rules and the impact of adverse capital and credit market conditions. These and other risks and assumptions are described in Item 1A. Risk Factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and in other documents that we file or furnish with the Securities and Exchange Commission. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements. All forward-looking statements speak only as of the date they are made, and we do not intend to update or revise any forward-looking statements even if new information becomes available in the future, except as required by law or applicable regulations. We operate in a highly competitive, highly regulated, and rapidly changing environment and our business is in a state of evolution. Therefore, it is likely that new risks will emerge, and that the nature and elements of existing risks will change, over time. It is not possible for management to predict all such risk factors or changes therein, or to assess either the impact of all such risk factors on our business or the extent to which any individual risk factor, combination of factors, or new or altered factors, may cause results to differ materially from those contained in any forward-looking statement.
Except where the context otherwise requires, in this Quarterly Report on Form 10-Q, the “Company,” “Imunon,” “we,” “us,” and “our” refer to Imunon, Inc., a Delaware corporation and its wholly owned subsidiary.

NOTES TO THE CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS
(UNAUDITED)
MARCH 31, 2026
Note 1. Business Description
Imunon, Inc. (“Imunon” , the “Company”, “we”, “our”, or “us”) is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms with the aim to generate safe, effective, and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. Imunon is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the coding of proteins and cytokines in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the coding of viral antigens that can elicit a strong immunological response. This technology may represent a promising platform for the development of vaccines in infectious diseases.
The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase II clinical trial (OVATION 2) and is currently conducting a Phase 3 clinical trial (OVATION 3). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.
Note 2. Basis of Presentation
The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. All significant intercompany balances and transactions have been eliminated in consolidation. During the quarter ended March 31, 2026, there were no changes to the Company’s accounting policies. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.
In the opinion of management, all adjustments, consisting only of normal recurring accruals considered necessary for a fair presentation, have been included in the accompanying unaudited condensed consolidated financial statements. Operating results for the three months ended March 31, 2026, and 2025 are not necessarily indicative of the results that may be expected for any other interim period(s) or for any full year. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the Securities and Exchange Commission on March 31, 2026.
The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the amounts reported in the Company’s financial statements and accompanying notes. Actual results could differ materially from those estimates. Events and conditions arising subsequent to the most recent balance sheet date have been evaluated for their possible impact on the financial statements and accompanying notes.
Significant Accounting Policies
Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements included in our 2025 Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 31, 2026. See Note 3 to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.
Going Concern Uncertainty
Since
inception, the Company has incurred substantial operating losses, principally from expenses associated with the Company’s research
and development programs, clinical trials conducted in connection with the Company’s drug candidates, and applications and submissions
to the FDA. The Company has not generated significant revenue and has incurred significant net losses in each year since inception. For
the quarter ended March 31, 2026, the Company had a net loss of $
| 6 |
The Company’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in the U.S. and worldwide resulting from the recent tariff announcement by the U.S. federal government, the Russian invasion of Ukraine and the unrest in the Middle East. The Company continues to monitor its operating activities in light of these events, and it is possible that these events could result in a variety of risks to the business. The specific impact, if any, is not readily determinable as of the date of these unaudited condensed consolidated financial statements.
The Company has based its estimates on assumptions that may prove to be wrong. The Company may need to obtain additional funds sooner or in greater amounts than it currently anticipates. Potential sources of financing include strategic relationships, public or private sales of the Company’s shares or debt and other sources. If the Company raises funds by selling additional shares of common stock or other securities convertible into common stock, the ownership interest of existing stockholders may be diluted.
The actual amount of funds the Company will need to operate is subject to many factors, some of which are beyond the Company’s control. These factors include the progress of research activities; the number and scope of research programs; the progress of preclinical and clinical development activities; the progress of the development efforts of parties with whom the Company has entered into research and development agreements; the costs associated with additional clinical trials of drug candidates; the ability to maintain current research and development licensing arrangements and to establish new research and development and licensing arrangements; the ability to achieve milestones under licensing arrangements; the costs involved in prosecuting and enforcing patent claims and other intellectual property rights; and the costs and timing of regulatory approvals.
A fundamental component of the ability to continue as a going concern is the Company’s ability to raise capital as required, as to which no assurances can be provided. To address the additional funding requirements of the Company, management has undertaken the following initiatives:
| ● | it has assessed its current expenditures and will reduce spending where necessary; | |
| ● | it will pursue additional capital funding in the public and private markets through equity sales and/or debt facilities; | |
| ● | it will pursue possible partnerships and collaborations; and | |
| ● | it will pursue potential out licensing for its drug candidates. |
The Company’s ability to continue as a going concern will depend on its ability to raise additional capital, attain further operating efficiencies, reduce expenditures, and, ultimately, to generate revenue. There are no assurances that these future funding and operating efforts will be successful. If management is unsuccessful in these efforts, the Company’s current capital is not expected to be sufficient to fund operations for the next twelve months.
Such conditions raise substantial doubts about the Company’s ability to continue as a going concern. Based on the above, management has determined there is substantial doubt regarding our ability to continue as a going concern. The report of our independent registered public accounting firm for the year ended December 31, 2025, includes an explanatory paragraph which expresses substantial doubt about our ability to continue as a going concern.
Management’s plan includes private or public equity financings, collaborations, or other strategic transactions such as raising funds from outside investors via its ATM program and other potential funding sources. The Company may not be able to obtain funding on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. The Company’s ability to raise additional funds will depend, among other factors, on financial, economic and market conditions, many of which are outside of its control, and it may be unable to raise financing when needed, or on terms favorable to the Company. If the Company is unable to obtain sufficient capital to fund its operations it may be required to evaluate alternatives. The Company’s condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets, carrying amounts or the amount and classification of liabilities that may be required should the Company be unable to continue as a going concern.
Note 3. New Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the FASB and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued accounting pronouncements will not have a material impact on the Company’s consolidated financial position, results of operations, and cash flows, or do not apply to its operations.
| 7 |
In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses” (“ASU 2024-03”). ASU 2024-03 will require more detailed information about the types of expenses in commonly presented income statement captions such as “Cost of sales” and “Selling, general and administrative expenses”. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact, if any, this change will have on the Company’s disclosures.
In December 2025, the FASB issued ASU 2025-11, “Narrow Scope Improvements” (“ASU 2025-11”) which is intended to improve the navigability of the guidance in Interim Reporting (Topic 270) and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides “interim financial statements and notes in accordance with GAAP.” ASU 2025-11 also addresses the form and content of such financial statements, adds lists to ASC 270 of the interim disclosures required by all other codification topics, and establishes a principle under which an entity must “disclose events since the end of the last annual reporting period that have a material impact on the entity.” As the FASB stated in the proposed guidance and reiterates in 2025-11, the amendments are not intended to “change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements”. ASU 2025-11 is effective for interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company does not believe ASU 2025-11 will have a material effect on its consolidated financial statements.
Other than the items noted above, there have been no new accounting pronouncements not yet effective or adopted in the current year that the Company believes have a material impact, or potential material impact, to its consolidated financial statements.
Note 4. Net Loss per Common Share
Basic and diluted net loss per common share was computed by dividing net loss for the year by the weighted average number of shares of common stock outstanding, both basic and diluted, during each period. The impact of common stock equivalents has been excluded from the computation of diluted weighted average common shares outstanding in periods where there is a net loss, as their effect is anti-dilutive.

The reverse stock split was previously approved by the Company’s stockholders at the 2025 Annual Meeting held on July 11, 2025, and the Company subsequently filed a Certificate of Amendment to its Certificate of Incorporation to affect the stock consolidation. The primary reasons for the reverse stock split and the amendment are:
| ● | To provide the Company with the ability to support its anticipated future growth and would provide greater flexibility to consider and respond to future business opportunities and needs as they arise, including equity financings and stock-based acquisitions of new technology and product development candidates. The availability of additional shares of Common Stock would permit the Company to undertake certain of the foregoing actions without delay and expense associated with holding a Special Meeting of Stockholders to obtain stockholder approval each time such an opportunity arises that would require the issuance of shares of Common Stock; and | |
| ● | To
continue listing on The NASDAQ Capital Market, which requires that the Company comply with the applicable listing requirements under
NASDAQ Marketplace Rules, which requirements include, among others, a minimum bid price of at least $ |

Overview
Imunon is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms with the aim to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. Imunon is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the coding of proteins and cytokines in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the coding of viral antigens that can elicit a strong immunological response. This technology may represent a promising platform for the development of vaccines in infectious diseases.
The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase II clinical trial (OVATION 2) and is currently conducting a Phase 3 clinical trial (OVATION 3). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.
Technology Platform
Imunon’s technology platform is optimized for the delivery of DNA and mRNA therapeutics via synthetic non-viral carriers and is capable of providing cell transfection for double-stranded DNA plasmids and large therapeutic RNA segments such as mRNA. There are two components to the system, a backbone with plasmid DNA or mRNA payload encoding therapeutic proteins, or pathogen antigens or tumor associated antigens or cancer neoantigens and a delivery system. The delivery system is designed to protect the DNA or mRNA from degradation and promote trafficking into cells and through intracellular compartments. We designed the delivery system by chemically modifying the low molecular weight polymer to improve its gene transfer activity without increasing toxicity. We believe that our non-viral DNA technology may be a viable alternative to current approaches to gene delivery due to several distinguishing characteristics, including enhanced molecular versatility that allows for complex modifications to potentially improve activity and safety.
The biocompatibility of these polymers reduces the risk of adverse immune response, thus allowing for repeated administration. Compared to naked DNA or cationic lipids, we believe that our delivery systems are generally more efficient, cost effective and have a more favorable safety profile. We believe that these advantages place Imunon in a position to capitalize on this technology platform.
THERAPLAS MODALITY:
IMNN-001 DEVELOPMENT PROGRAM
Ovarian Cancer Overview
Ovarian cancer is the most lethal of gynecological malignancies among women with more than 60% of women dying within five years of diagnosis. This poor outcome is due in part to the lack of effective prevention and early detection strategies. There were approximately 20,000 new cases of ovarian cancer in the U.S. in 2021 with an estimated 13,000 deaths. Mortality rates for ovarian cancer declined very little in the last 40 years due to the unavailability of detection tests and improved treatments. Most women with ovarian cancer are not diagnosed until Stages III or IV, when the disease has spread outside the pelvis to the abdomen and areas beyond, causing swelling and pain. With the five-year survival rates for Stages III and IV at 41% and 20%, respectively, there remains a need for a therapy that not only reduces the recurrence rate but also meaningfully improves overall survival. Patients whose cancer recurs or progresses after initially responding to surgery and first-line chemotherapy have been divided into one of the two groups based on the time from completion of platinum therapy to disease recurrence or progression. This time period is referred to as platinum-free interval. The platinum-sensitive group has a platinum-free interval of longer than six months. This group generally responds to additional treatment with platinum-based therapies. The platinum resistant group has a platinum-free interval of shorter than six months and is resistant to additional platinum-based treatments. Pegylated liposomal doxorubicin, topotecan, and bevacizumab are the only approved second-line therapies for platinum-resistant ovarian cancer. The overall response rate for these therapies is 10% to 20% with median overall survival (“OS”) of 11 to 12 months. Additionally, 10% to 15% of ovarian cancer cases nationwide are a result of germline or somatic BRCA mutations. With cognizance of tumor genetics, practice has shifted to include targeted agents in ovarian cancer treatment.
| 15 |
Poly (ADP-ribose) polymerase (“PARP”) enzymes are responsible for detecting and repairing single-stranded and double-stranded DNA breaks during cell replication. BRCA1/2 mutations hinder the homologous recombination repair pathway, and tumor cells utilize PARP enzymes to repair DNA. For this reason, these tumors are particularly sensitive to the mechanism of PARP inhibitors. PARP inhibitors have expanded treatment options in ovarian cancer, but few treatment options are left for women who are not eligible to receive PARP inhibitors.
Immunotherapy is an attractive, novel approach for the treatment of ovarian cancer particularly since ovarian cancers are considered immunogenic tumors. Interleukin-12 (“IL-12”) is one of the most active cytokines for the induction of potent anti-cancer immunity acting through the induction of T-lymphocyte and natural killer cell proliferation. The precedence for a therapeutic role of IL-12 in ovarian cancer is based on epidemiologic and clinical and preclinical data.
IMNN-001 Immunotherapy
IMNN-001 is a DNA-based immunotherapeutic drug candidate for the localized treatment of ovarian cancer by intraperitoneally administering an IL-12 plasmid formulated with our proprietary TheraPlas delivery system. In this DNA-based approach, the immunotherapy is combined with a standard chemotherapy drug, which can potentially achieve better clinical outcomes than with chemotherapy alone. We believe that increases in IL-12 concentrations at tumor sites for several days after a single administration could create a potent immune environment against tumor activity and that a direct killing of the tumor with concomitant use of cytotoxic chemotherapy could result in a more robust and durable antitumor response than chemotherapy alone. We believe the rationale for local therapy with IMNN-001 is based on the following:
| ● | Loco-regional production of the potent cytokine IL-12 avoids toxicities and poor pharmacokinetics associated with systemic delivery of recombinant IL-12; | |
| ● | Persistent local delivery of IL-12 lasts up to one week and dosing can be repeated; and | |
| ● | Local therapy is ideal for long-term maintenance therapy. |
OVATION 1 Study. In February 2015, we announced that the FDA accepted the Phase I dose-escalation clinical trial of IMNN-001 in combination with the standard of care in neoadjuvant ovarian cancer (the “OVATION 1 Study”). The OVATION 1 Study was designed to:
| ● | identify a tolerable and therapeutically active dose of IMNN-001 within certain safety parameters by recruiting and maximizing an immune response; | |
| ● | enroll three to six patients per dose level and evaluate safety and efficacy; and | |
| ● | attempt to define an optimal dose for a follow-on Phase I/II study. |
In addition, the OVATION 1 Study established a unique opportunity to assess how cytokine-based compounds such as IMNN-001 directly affect ovarian cancer cells and the tumor microenvironment in newly diagnosed ovarian cancer patients. The study was designed to characterize the nature of the immune response triggered by IMNN-001 at various levels of the patients’ immune system, including:
| ● | Infiltration of cancer fighting T-cell lymphocytes into primary tumor and tumor microenvironment including peritoneal cavity, which is the primary site of metastasis of ovarian cancer; | |
| ● | Changes in local and systemic levels of immuno-stimulatory and immune-suppressive cytokines associated with tumor suppression and growth, respectively; and | |
| ● | Expression profile of a comprehensive panel of immune related genes in pre-treatment and IMNN-001-treated tumor tissue. |
| 16 |
During 2016 and 2017, we announced data from the first 14 patients in the OVATION 1 Study. On October 3, 2017, we announced final translational research and clinical data from the OVATION 1 Study.
Key translational research findings from all evaluable patients are summarized below:
| ● | The intraperitoneal treatment of IMNN-001 in conjunction with standard-of-care neoadjuvant chemotherapy (“NACT”) resulted in dose-dependent increases in IL-12 and Interferon-gamma (IFNγ) levels that were predominantly in the peritoneal fluid compartment with little to no changes observed in the patients’ systemic circulation. These and other post-treatment changes including decreases in VEGF levels in peritoneal fluid were consistent with an IL-12 based immune mechanism; | |
| ● | Consistent with the previous partial reports, the effects observed in the Immunohistochemistry analysis were pronounced decreases in the density of immunosuppressive T-cell signals (Foxp3, PD-1, PDL-1, IDO-1) and increases in CD8+ cells in the tumor microenvironment; | |
| ● | The ratio of CD8+ cells to immunosuppressive cells was increased in approximately 75% of patients, suggesting an overall shift in the tumor microenvironment from immunosuppressive to pro-immune stimulatory following treatment with IMNN-001. An increase in CD8+ to immunosuppressive T-cell populations was a leading indicator and believed to be a good predictor of improved OS; and | |
| ● | Analysis of peritoneal fluid by cell sorting, not reported before, showed a treatment-related decrease in the percentage of immunosuppressive T-cell (Foxp3+), which was consistent with the reduction of Foxp3+ T-cells in the primary tumor tissue, and a shift in tumor naïve CD8+ cell population to more efficient tumor killing memory effector CD8+ cells. |
The Company reported encouraging clinical data from the first 14 patients who completed treatment in the OVATION 1 Study. IMNN-001 plus standard chemotherapy produced no dose-limiting toxicities and positive dose dependent efficacy signals which correlate well with positive surgical outcomes as summarized below:
| ● | Of the 14 patients treated in the entire study, two patients demonstrated a complete response, 10 patients demonstrated a partial response, and two patients demonstrated stable disease, as measured by Response Evaluation Criteria in Solid Tumors (“RECIST”) criteria. This translated to a 100% disease control rate and an 86% objective response rate (“ORR”). Of the five patients treated in the highest dose cohort, there was a 100% ORR with one complete response and four partial responses; | |
| ● | 14 patients had successful resections of their tumors, with nine patients (64%) having a complete tumor resection (“R0”), which indicates a microscopically margin-negative resection in which no gross or microscopic tumor remains in the tumor bed. Seven out of eight (88%) patients in the highest two dose cohorts experienced a R0 surgical resection. All five patients treated at the highest dose cohort experienced a R0 surgical resection; and | |
| ● | All patients experienced a clinically significant decrease in their CA-125 protein levels. CA-125 was used to monitor certain cancers during and after treatment. CA-125 was present in greater concentrations in ovarian cancer cells than in other cells. |
On March 26, 2020, the Company announced with Medidata Solutions, a subsidiary of Dassault Systèmes, that examining matched patient data provided by Medidata in a synthetic control arm (“SCA”) with results from the Company’s Phase I dose-escalating OVATION 1 Study showed positive results in progression-free survival (“PFS”). The hazard ratio (“HR”) was 0.53 in the intent-to-treat (“ITT”) group, showing strong signals of efficacy. In its March 2019 discussion with the Company, the FDA noted that preliminary findings from the Phase I OVATION 1 Study were exciting but lacked a control group to evaluate IMNN-001’s independent impact on impressive tumor response, surgical results and PFS. The FDA encouraged the Company to continue its IMNN-001 development program and consult with FDA with new findings that may have a bearing on designations such as Fast Track and Breakthrough Therapy.
On July 29, 2021, the Company announced final PFS results from the OVATION 1 Study published in the Journal of Clinical Cancer Research. Median PFS in patients treated per protocol (n=14) was 21 months and was 18.4 months for the ITT population (n=18) for all dose cohorts, including three patients who dropped out of the study after 13 days or less, and two patients who did not receive full NACT and IMNN-001 cycles. Under the current standard of care, in women with Stage III/IV ovarian cancer undergoing NACT, their disease progresses within about 12 months on average. The results from the OVATION 1 Study supported continued evaluation of IMNN-001 based on promising tumor response, as reported in the PFS data, and the ability for surgeons to completely remove visible tumors at the time of interval debulking surgery. IMNN-001 was well tolerated, and no dose-limiting toxicities were detected in the OVATION 1 Study. Intraperitoneal administration of IMNN-001 was feasible with broad patient acceptance.
| 17 |
OVATION 2 Study. The Company held an Advisory Board Meeting on September 27, 2017 with clinical investigators and scientific experts including those from Roswell Park Cancer Institute, Vanderbilt University Medical School, and M.D. Anderson Cancer Center to review and finalize clinical, translational research and safety data from the OVATION 1 Study to determine the next steps forward for our IMNN-001 immunotherapy program. On November 13, 2017, the Company filed its Phase I/II clinical trial protocol with the FDA for IMNN-001 for the localized treatment of ovarian cancer. The protocol was designed with a single dose escalation phase to 100 mg/m² to identify a tolerable dose of IMNN-001 within certain safety parameters while maximizing an immune response. The Phase I portion of the study would be followed by a continuation at the selected dose in approximately 110 patients randomized Phase II study.
In the OVATION 2 Study, patients in the IMNN-001 treatment arm would receive IMNN-001 plus chemotherapy pre- and post-interval debulking surgery (“IDS”). The OVATION 2 Study was designed to include up to 110 patients with Stage III/IV ovarian cancer, with 15 patients in the Phase I portion and up to 95 patients in Phase II. The sample size is consistent with a Phase II trial designed to inform the design of a Phase III trial comparing IMNN-001 with neoadjuvant + adjuvant chemotherapy versus neoadjuvant + adjuvant chemotherapy alone. As a Phase II study, the OVATION 2 Study was not powered for statistical significance. The primary endpoint is PFS and the primary analysis would be conducted after at least 80 events had been observed or after all patients had been followed for at least 16 months, whichever was later. Additional endpoints included objective response rate, overall survival, chemotherapy response score, and surgical response.
In March 2020, the Company announced encouraging initial clinical data from the first 15 patients enrolled in the Phase I portion of the OVATION 2 Study for patients newly diagnosed with Stage III and IV ovarian cancer. The OVATION 2 Study was designed to combine IMNN-001, the Company’s IL-12 gene-mediated immunotherapy, with standard-of-care NACT. Following NACT, patients undergo IDS, followed by three additional cycles of chemotherapy.
IMNN-001 plus standard-of-care NACT produced positive dose-dependent efficacy results, with no dose-limiting toxicities, which correlate well with successful surgical outcomes as summarized below:
| ● | Of the 15 patients treated in the Phase I portion of the OVATION 2 Study, nine patients were treated with IMNN-001 at a dose of 100 mg/m² plus NACT and six patients were treated with NACT only. All 15 patients had successful resections of their tumors, with eight out of nine patients (88%) in the IMNN-001 treatment arm having an R0 resection. Only three out of six patients (50%) in the NACT only treatment arm had a R0 resection. | |
| ● | When combining these results with the surgical resection rates observed in the Company’s OVATION 1 Study, a population of patients with inclusion criteria identical to the OVATION 2 Study, the data reflected the strong dose-dependent efficacy of adding IMNN-001 to the current standard of care NACT: |

| ● | The ORR as measured by RECIST criteria for the 0, 36, 47 mg/m² dose IMNN-001 patients were comparable, as expected, to the higher (61, 79, 100 mg/m²) dose IMNN-001 patients, with both groups demonstrating an approximate 80% ORR. |
On March 23, 2020, the Company announced that the European Medicines Agency (the “EMA”) Committee for Orphan Medicinal Products (“COMP”) had recommended that IMNN-001 be designated as an orphan medicinal product for the treatment of ovarian cancer. IMNN-001 previously received orphan designation from the FDA.
In February 2021, the Company announced that it had received Fast Track designation from the FDA for IMNN-001 and also provided an update on the OVATION 2 Study. The Company reported that approximately one-third, or 34 patients, of the anticipated 110 patients had been enrolled into the OVATION 2 Study, of which 20 were in the treatment arm and 14 were in the control. Of the 34 patients enrolled in the trial, 27 patients have had their IDS with the following results:
| ● | 80% of patients treated with IMNN-001 had a R0 resection. | |
| ● | 58% of patients in the control arm had an R0 resection. | |
| ● | These interim data represented a 38% improvement in R0 resection rates for IMNN-001 patients compared with control arm patients and was consistent with the reported improvement in resection scores noted in our Phase I OVATION 1 Study, the manuscript of which was submitted for peer review publication. |
| 18 |
In June 2022, the Company announced that following a pre-planned interim safety review of 87 as treated patients (46 patients in the experimental arm and 41 patients in the control arm) randomized in the OVATION 2 Study, the Data Safety Monitoring Board (“DSMB”) unanimously recommended that the OVATION 2 Study continue treating patients with the dose of 100 mg/m2. The DSMB also determined that safety was satisfactory, with an acceptable risk/benefit, and that patients tolerated IMNN-001 during a course of treatment that would last up to six months. No dose-limiting toxicities were reported at this point in the OVATION 2 Study. Interim clinical data from patients who had undergone IDS showed that the IMNN-001 treatment arm was continuing to show improvement in R0 surgical resection rates and CRS 3 chemotherapy response scores over the control arm. The chemotherapy response score is a three-tier standardized scoring system for histological tumor regression into complete/near complete (CRS 3), partial (CRS 2) and no/minimal (CRS 1) response based on omental examination.
In September 2022, the Company announced that its Phase I/II OVATION 2 Study with IMNN-001 in advanced ovarian cancer had completed enrollment with 113 patients. In September 2023, the Company announced interim PFS and OS data with IMNN-001 in its Phase I/II OVATION 2 Study. Interim clinical data from the ITT population showed efficacy trends in PFS, demonstrating a delay in disease progression in the treatment arm of approximately 33% compared with the control arm, with the hazard ratio nearing the required value. Preliminary OS data followed a similar trend, showing an approximate 9-month improvement in the treatment arm over the control arm.
Subgroup analyses showed patients treated with a PARP inhibitor (“PARPi”) as maintenance therapy had longer PFS and OS if they were also treated with IMNN-001 compared with patients treated with NACT only. This was not a pre-specified subgroup as PARP inhibitors were approved after the OVATION 2 Study was initiated.
| ● | The median PFS in the PARPi + NACT group and the PARPi + NACT + IMNN-001 group was 15.7 months and 23.7 months, respectively. | |
| ● | The median OS in the PARPi + NACT group was 45.6 months and has not yet been reached in the PARPi + NACT + IMNN-001 group. |
Imunon also continues to see benefits in other secondary endpoints including an approximately 20% higher R0 tumor resection score and a doubling of the CRS 3 chemotherapy response score to approximately 30% in the treatment arm versus 14% in the control arm. Chemotherapy response score is considered a good prognostic indicator in ovarian cancer. The DSMB determined that safety analyses continue to show good tolerability of IMNN-001 in this setting.
In June 2024, the Company announced database lock for the OVATION 2 Study. At that time, median OS and PFS had been reached, and all patients in the open-label study had achieved treatment observation duration of 16 months, as required by protocol to evaluate efficacy. On July 11, 2024, a scientific advisory board with DSMB members, principal investigators, and scientific experts was held to review efficacy and safety data from the OVATION 2 study.
On July 30, 2024, the Company announced positive topline results from the Phase I/II OVATION 2 Study. Highlights from patients treated with IMNN-001 plus standard-of-care in a first-line treatment setting include:
| ● | An 11.1 month increase in median OS compared with standard-of-care alone in the ITT population. | |
| ● | A hazard ratio in the ITT population of 0.74, which indicates a 35% improvement in survival. | |
| ● | Among the approximately 90% of trial participants who received at least 20% of specified treatments per-protocol in both study arms, patients in the IMNN-001 arm had a 15.7 month increase in median OS, representing a further extension of life with a hazard ratio of 0.64, a 56% improvement in survival. | |
| ● | For nearly 40% of trial participants treated with a PARP inhibitor, the hazard ratio decreased further to 0.41, with median OS in the IMNN-001 treatment arm not yet reached at the time of database lock, compared with median OS of 37.1 months in the standard-of-care treatment arm. |
The PFS results, the trial’s primary endpoint, support the OS results with:
| ● | A three-month improvement in PFS compared with standard-of-care alone. | |
| ● | A hazard ratio in the intent-to-treat population of 0.79, indicating a 27% improvement in delaying progression for the IMNN-001 treatment arm. |
These initial results from the OVATION 2 Study were presented in a late-breaking session at the Society for Immunotherapy of Cancer (SITC) 39th Annual Meeting in November 2024.

On September 11, 2024, a scientific advisory board was held with DSMB members, principal investigators, and scientific experts to discuss and seek input on the protocol synopsis for the Phase III trial. A protocol synopsis was submitted along with a briefing document for review and input at the End-of-Phase II (“EOP2”) meeting with the U.S. Food and Drug Administration focused on the Phase III study. The EOP2 meeting was conducted in the fourth quarter of 2024.
| ● | The positive outcome of the EOP2 in-person meeting with the U.S. Food and Drug Administration (FDA), supported the advancement of IMNN-001 for the treatment of advanced ovarian cancer into a Phase 3 pivotal study. The interaction with the FDA included an extensive review of data generated to date, including positive results from the recently completed Phase 2 OVATION 2 Study, which assessed IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin compared to standard-of-care NACT alone in 112 patients with newly diagnosed advanced ovarian cancer. Treatment was also generally well tolerated, with no reports of cytokine release syndrome or any other serious immune-related adverse events. | |
| ● | The Company also held a Type C Chemistry, Manufacturing, and Controls (CMC) meeting with the FDA regarding production of IMNN-001 for the treatment of women with newly diagnosed advanced ovarian cancer. The goal of the meeting was to seek alignment and agreement with the FDA on key CMC topics to support IMNN-001 production for the planned Phase 3 pivotal trial and a potential future new biologic license application (BLA) submission. The meeting with the FDA included a review of the Company’s current good manufacturing practice (cGMP) clinical-scale and commercial manufacturing process for IMNN-001, conducted at the Company’s manufacturing facility based in Huntsville, Alabama. The Agency agreed that the Company’s potency assay which measures interferon-gamma (IFN-γ) is acceptable for the Phase 3 clinical study and for use in a commercial setting for release of drug product. The FDA also agreed with the Company’s strategy to establish comparability of the core components of IMNN-001 produced by the Company with product previously produced through an external contract development and manufacturing organization. |
In December 2024, the Company announced additional clinical data from ongoing analyses of results from the Phase 2 OVATION 2 Study. The updated results (including a post announcement, immaterial statistical correction), based on an additional seven months of patient monitoring, showed the following:
| ● | The hazard ratio (HR) decreased from 0.74 to 0.70 in the ITT population, with an increase in median overall survival (OS) from 11.1 to 13 months following treatment with IMNN-001 plus standard-of-care (SoC) neoadjuvant and adjuvant chemotherapy (NACT) versus SoC alone. | |
| ● | More than one-third of patients in the trial survived more than 36 months from the point of study enrollment, with 62% of those surviving patients from the IMNN-001 treatment arm and 38% from the SoC arm. Over 10% of trial participants have reached 48 months or beyond. |
In June 2025, the Company announced positive data from the Company’s Phase 2 OVATION 2 Study showing that treatment with IMNN-001 in women with newly diagnosed advanced ovarian cancer resulted in consistent, clinically meaningful improvements in several key endpoints across treatment groups, including overall survival (OS), progression-free survival (PFS), chemotherapy response score and surgical response. Treatment with IMNN-001 also showed a favorable safety profile, with no reports of serious immune-related adverse events. The full results were presented in an oral presentation at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois, and simultaneously published in the peer-reviewed journal Gynecologic Oncology. The data presented highlighted the following results achieved across all treatment groups:
| ● | Median 13-month increase in OS and median 3-month increase in PFS in IMNN-001 treatment arm compared to standard of care alone. | |
| ● | Better therapeutic effect observed with IMNN-001 treatment compared to the control arm (p=0.0375), as shown by mean 6.5-month extension of time free of progression or death (PFS + OS) captured in totality of treatment effect. | |
| ● | Use of poly ADP-ribose polymerase (PARP) inhibitors as part of maintenance therapy further enhanced outcomes, with median OS not yet reached in IMNN-001 treatment arm after >5 years compared to 37 months on standard of care. | |
| ● | Chemotherapy response score highlights double the response rate of a complete or near complete histopathological response following treatment with 26.1% in the IMNN-001 treatment arm compared to 13.0% in the control arm. |
| 20 |
| ● | Surgical response rate of no macroscopic residual tumor left after surgery 64.6% in the IMNN-001 treatment arm compared to 52.1% in the control arm. | |
| ● | Hazard ratio of 0.78 in study participants who are homologous recombination proficient (HRP) and hazard ratio of 0.42 in women positive for homologous recombination deficiency (HRD+), including BRCA1 or BRCA2 mutations, suggesting increased therapeutic activity. | |
| ● | IMNN-001 was generally safe and well tolerated, with no reports of cytokine release syndrome, systemic toxicity or serious immune-related adverse events. |
On June 18, 2025, the Company presented positive translational data from the OVATION 2 Study of IMNN-001 at the ESMO Gynecological Cancers Congress 2025, that took place on June 19-21, 2025, in Vienna, Austria. Results presented at the ESMO Congress showed that treatment with IMNN-001 induced substantial increases in IL-12 and interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α), key downstream anti-cancer immune cytokines. Increases in IL-12, IFN-γ and TNF-α levels in the peritoneal cavity were approximately 27-, 62- and 36-fold following treatment, respectively, demonstrating the tumor-localized effect of IMNN-001 in women with advanced ovarian cancer. IMNN-001 continues to show a favorable safety profile.
In September 2025, the Company presented additional positive translational data from the OVATION 2 Study at the American Association for Cancer Research (AACR) Special Conference in Cancer Research: Advances in Ovarian Cancer Research reinforcing the favorable safety profile and efficacy benefits of IMNN-001 observed in the clinic, including increases in key anti-cancer immune cytokines and modulation of relevant anti-tumor immune cell populations, such as CD8+ T cells and myeloid dendritic cells, in the tumor and tumor microenvironment in study participants post-treatment. Results presented at the AACR Special Conference demonstrated:
| ● | Positive shift in the local TME to favorable immune stimulatory T cell ratios in the majority of participants treated with IMNN-001, including favorable ratios of CD8+/T regulatory (Treg) cells, CD8+/IDO+ cells, and CD8+/CD4+ cells. | |
| ● | TME shift in favor of decreased immunosuppression cells (IDO+, PDL1+, Treg, CD4+) and increased immunostimulatory cells (CD8+, CD8+ effector, myeloid dendritic cells) in the majority of participants post-treatment. | |
| ● | IMNN-001 treatment creates a “hot” anti-TME by increasing the recruitment of anti-tumor CD8+ and myeloid dendritic cells in 50-80% of the paired samples and decreasing immunosuppressive markers (IDO, PDL1, Treg cells) in 65-80% of the samples. | |
| ● | IMNN-001 continues to show a favorable safety profile. |
Results from the study continue to validate our TheraPlas® technology and the broad impact of IMNN-001 on important cancer-fighting cytokines, effectively turning the tumor microenvironment from “cold” to ‘hot’ by activating both innate and adaptive immune systems, with limited to no systemic toxicities.
On November 10, 2025, the Company held a R&D Day which showcased recent progress with its IMNN-001 development program for the treatment of newly diagnosed advanced ovarian cancer, including a review of positive data from the Company’s Phase 2 OVATION 2 Study and the minimal residual disease (MRD) study conducted in partnership with Break Through Cancer.
R&D Day Featured Speakers and Program Highlights:
| ● | Premal H. Thaker, M.D., Washington University School of Medicine, discussed the significant continuing unmet needs in ovarian cancer, a devastating disease where patient outcomes and frontline standard of care treatment have not changed for about 30 years, and the promise IMNN-001 brings to these patients and clinicians. She highlighted the data from the Phase 2 OVATION 2 clinical trial, with results including: |
| ○ | Broad impact observed with IMNN-001 treatment on important cancer-fighting cytokines, effectively turning the tumor microenvironment from “cold” to “hot” by activating both innate and adaptive immune systems, renewing the elusive promise of an immunotherapy for ovarian cancer. | |
| ○ | Data reinforcing the highly favorable benefit-risk and safety profile of IMMN 001. | |
| ○ | The median 13-month overall survival (OS) benefit observed with IMNN-001 plus standard of care (SoC) chemotherapy, an increase that is considered clinically meaningful compared to SoC alone. |
| 21 |
| ● | Amir Jazaeri, M.D., University of Texas MD Anderson Cancer Center, discussed safety, tolerability and translational insights from the Phase 2 MRD study of IMNN-001, including: |
| ○ | Rationale for the trial and the importance of frontline therapy as the best opportunity to achieve a cure for ovarian cancer. | |
| ○ | New translational data that clearly showed IMNN-001 preferentially being taken up by macrophages within the peritoneal fluid and tumor tissue, which then induces a robust response and tumor microenvironment remodeling. | |
| ○ | New data further supporting the highly favorable benefit-risk and tolerability profile of IMNN-001. | |
| ○ | The positive tolerability profile of IMNN-001, including in combination with SoC chemotherapy plus bevacizumab and in the maintenance setting. |
| ● | Giorgio Paulon, Ph.D., Berry Consultants, LLC, reviewed the Phase 2 and ongoing Phase 3 trial designs and the strength of evidence for IMNN-001 from a statistical perspective. He highlighted the well-precedented nature of the Phase 3 design with the FDA, which leverages an innovative, adaptive, event-driven approach aligned with prior successful oncology trials that resulted in full approval by FDA based on interim analyses of overall survival. |
| ● | Douglas V. Faller, M.D., Ph.D., Imunon’s Chief Medical Officer, presented new data further demonstrating that IMNN-001 shifted the balance in favor of immune stimulation, remodeling the tumor microenvironment in favor of anti-tumor responses, which is established to be associated with better prognosis. He shared the rapid progress to-date on the Phase 3 trial of IMNN-001, including expansion to additional sites and enrollment exceeding the Company’s expectations, strong levels of support and interest from investigators and the scientific community, and key clinical and other milestones for the company moving forward. |
On March 25, 2026, the Company announced final data from the completed Phase 2 OVATION 2 clinical trial evaluating IMNN-001 in combination with standard of care (SoC) neoadjuvant and adjuvant chemotherapy. Imunon initially reported a median 11.1 month increase in overall survival (40.5 vs. 29.4 months) in the IMNN-001 treatment arm compared to SoC chemotherapy alone. Following the final data assessment, the Company reported a median 14.7 month increase in overall survival (45.1 vs. 30.4 months) in women in the IMNN-001 treatment arm compared to SoC alone, demonstrating continuous improvement in overall survival (3.6 delta). In addition, the final IMNN-001 data showed that women treated with IMNN-001 and SoC chemotherapy plus poly ADP-ribose polymerase (PARP) inhibitors as part of maintenance therapy achieved a median increase in overall survival of 24.2 months (65.6 vs. 41.4 months) compared to SoC chemotherapy alone.
Importantly, with these final efficacy results, IMNN-001 continued to show a highly favorable safety and tolerability profile across all clinical trials, further reinforcing the potential of this IL-12 immunotherapy to represent an important advance in the treatment of ovarian cancer.
OVATION 3 Study. On September 11, 2024, a scientific advisory board was held with DSMB members, principal investigators, and scientific experts to discuss and seek input on the protocol synopsis for the Phase III trial. A protocol synopsis was submitted along with a briefing document for review and input at the End-of-Phase II (“EOP2”) meeting with the U.S. Food and Drug Administration focused on the Phase III study. The EOP2 meeting was conducted in the fourth quarter of 2024.

The Phase 3 OVATION 3 trial will assess the safety and efficacy of IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin compared to standard of care (SoC) NACT alone. Study participants are being randomized 1:1 and include women with newly diagnosed advanced ovarian cancer (stage 3 or 4) who are eligible for neoadjuvant therapy, the intent-to-treat (ITT) population, with a sub-group of women positive for homologous recombination deficiency (HRD) including BRCA1 or BRCA2 mutations. Participants who are HRD positive will receive poly (ADP-ribose) polymerase (PARP) inhibitors as part of standard maintenance therapy. The primary endpoint of the study is overall survival (OS), and secondary endpoints are surgical response score, chemotherapy response score, clinical response and time to second-line treatment. The study will also assess several exploratory endpoints.
In March 2025, the Company announced that the FDA is aligned with the protocol for the Phase 3 OVATION 3 pivotal trial of its lead candidate IMNN-001 in development for the treatment of women with newly diagnosed advanced ovarian cancer. The Company is currently enrolling patients at four trial sites with additional sites being considered for activation.
As of March 31, 2026, seven sites are open to recruitment, Providence Sacred Heart Medical Center & Children’s Hospital, Washington University School of Medicine in St. Louis, Providence Cancer Institute in Portland, Erlanger Health in Chattanooga, Advent Health, Sanford Health, and the Medical College of Wisconsin with up to 43 additional sites being considered for activation. As of March 31, 2026, enrollment in the ITT population remains on track to complete enrolment by the first half of 2029.
IMNN-001 in Combination with Bevacizumab. In February 2023, the Company and Break Through Cancer, a public foundation dedicated to supporting translational research in the most difficult-to-treat cancers that partners with top cancer research centers, announced the commencement of patient enrollment in a collaboration to evaluate IMNN-001 in combination with bevacizumab in patients with advanced ovarian cancer in the frontline, neoadjuvant clinical setting.
This Phase I/II study, titled “Targeting Ovarian Cancer Minimal Residual Disease (MRD) Using Immune and DNA Repair Directed Therapies,” is expected to enroll 50 patients with Stage III/IV advanced ovarian cancer and is being led by principal investigator Amir Jazaeri, M.D., Vice Chair for Clinical Research and Director of the Gynecologic Cancer Immunotherapy Program in the Department of Gynecologic Oncology and Reproductive Medicine at MD Anderson. Dana-Farber Cancer Institute, The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins and Memorial Sloan Kettering Cancer Center will also be participating in the trial. In addition, The Koch Institute for Integrative Cancer Research at the Massachusetts Institute of Technology (MIT) will provide artificial intelligence services including biomarker and genomic analysis.
Patients are randomized 1:1 in a two-arm trial. In October 2023, the first patient began treatment at University of Texas MD Anderson Cancer Center in the Phase I/II Clinical Trial Evaluating IMNN-001 in Combination with Bevacizumab in Advanced Ovarian Cancer. The trial’s primary endpoint is detection of minimal residual disease (MRD) by second look laparoscopy (SLL), and the secondary endpoint is PFS. SLL data are expected within one year following the completion of enrollment and final PFS data are expected approximately three years following the completion of enrollment. This trial will also include a wealth of translational endpoints aimed at understanding the clonal evolution and immunogenomic features of the MRD phase of ovarian cancer that is currently undetectable by imaging or tumor markers.
A review of the MRD study accomplishments as of September 19, 2025, was conducted and it was determined that study goals contributing to the IMNN-001 development plan and Break Through Cancer study objectives can be accomplished in a trial of 30 patients. A decision was made to complete enrollment of the trial once the ITT population has reached 30 patients.
As of March 31, 2026, the ITT population was at twenty-two (22) patients randomized and treated in the study at the University of Texas MD Anderson Cancer Center and Memorial Sloan Kettering Cancer Center. and Stephenson Cancer Center at University of Oklahoma have been added as clinical sites for this study and are open to recruitment.

PLACCINE DNA VACCINE MODALITY: IMNN-101
Imunon’s PLACCINE DNA vaccine modality (“PLACCINE”) is a novel DNA-based, investigational vaccine for preventing or treating infections from a broad range of infectious agents and is We believe it is adaptable to creating vaccines for a multitude of pathogens, including emerging pathogens leading to pandemics as well as infectious diseases that have yet to be effectively addressed with current vaccine technologies. This flexible vaccine platform is well supported by an established supply chain to produce any plasmid vector and its assembly into a respective vaccine formulation.
The need for new vaccine technologies is urgent. Since 1980, more than 80 pathogenic viruses have been discovered, yet fewer than 4% have a commercially available prophylactic vaccine. We have engaged with the Biomedical Advanced Research and Development Authority (“BARDA”), a division of the U.S. Department of Health and Human Services, to consider certain pathogens BARDA has identified as the most urgent and the most important.
PLACCINE is an extension of the Company’s synthetic, non-viral TheraPlas delivery technology currently in development for the treatment of late-stage ovarian cancer with IMNN-001. Imunon’s proprietary multifunctional DNA vaccine technology concept is built on the flexible PLACCINE technology platform that is amenable to rapidly responding to the SARS-CoV-2 virus, as well as possible future mutations of SARS-CoV-2, other future pandemics, emerging bioterrorism threats, and novel infectious diseases. Imunon’s extensive experience with TheraPlas suggests that the PLACCINE-based nanoparticles are stable at storage temperatures of 4°C to 25°C, making vaccines developed on this platform easily suitable for broad world-wide distribution.
Imunon’s vaccine approach is designed to optimize the quality of the immune response dictating the efficiency of pathogen clearance and patient recovery. Imunon has taken a multivalent approach in an effort to generate an even more robust immune response that not only results in a strong neutralizing antibody response, but also a more robust and durable T-cell response. Delivered with Imunon’s synthetic polymeric system, the proprietary DNA plasmid is protected from degradation and its cellular uptake is facilitated.
Our Next Generation Vaccine Initiative
Imunon’s vaccine candidate comprises a single plasmid vector containing the DNA sequence encoding multiple SARS-CoV-2 antigens. Delivery will be evaluated intramuscularly, intradermally, or subcutaneously with a non-viral synthetic DNA delivery carrier that facilitates vector delivery into the cells of the injected tissue and has potential immune adjuvant properties. Unique designs and formulations of Imunon vaccine candidates may offer several potential key advantages. The synthetic polymeric DNA carrier is an important component of the vaccine composition as it has the potential to facilitate the vaccine immunogenicity by improving vector delivery and, due to potential adjuvant properties, attract professional immune cells to the site of vaccine delivery.
Future vaccine technology will need to address viral mutations and the challenges of efficient manufacturing, distribution, and storage. We believe the adaptation of our TheraPlas technology, PLACCINE, has the potential to meet these challenges. Our approach is summarized as a DNA vaccine technology platform characterized by a single plasmid DNA with multiple coding regions. The plasmid vector is designed to express multiple pathogen antigens. It is delivered via a synthetic delivery system and has the potential to be easily modified to create vaccines against a multitude of infectious diseases, addressing:
| ● | Viral Mutations: PLACCINE may offer broad-spectrum and mutational resistance (variants) by targeting multiple antigens on a single plasmid vector. | |
| ● | Durable Efficacy: PLACCINE delivers a DNA plasmid-based antigen that could result in durable antigen exposure and a robust vaccine response to viral antigens. | |
| ● | Storage & Distribution: PLACCINE allows for stability that is compatible with manageable vaccine storage and distribution. | |
| ● | Simple Dosing & Administration: PLACCINE is a synthetic delivery system that should require a simple injection that does not require viruses or special equipment to deliver its payload. |
On September 2, 2021, the Company announced results from preclinical in vivo studies showing production of antibodies and cytotoxic T-cell response specific to the spike antigen of SARS-CoV-2 when immunizing BALB/c mice with the Company’s next-generation PLACCINE DNA vaccine platform. Moreover, the antibodies to SARS-CoV-2 spike antigen prevented the infection of cultured cells in a viral neutralization assay. The production of antibodies predicts the ability of PLACCINE to protect against SARS-CoV-2 exposure, and the elicitation of cytotoxic T-cell response shows the vaccine’s potential to eradicate cells infected with SARS-CoV-2. These findings demonstrated the potential immunogenicity of Imunon’s PLACCINE DNA vaccine, which is intended to provide broad-spectrum protection and resistance against variants by incorporating multiple viral antigens, to improve vaccine stability at storage temperatures of 4°C and above, and to facilitate cheaper and easier manufacturing.

On January 31, 2022, the Company announced the initiation of a nonhuman primate (“NHP”) challenge study with Imunon’s DNA-based approach for a SARS-CoV-2 vaccine. The NHP pilot study followed the generation of encouraging mouse data and will evaluate the Company’s lead vaccine formulations for safety, immunogenicity and protection against SARS-CoV-2. In completed preclinical studies, Imunon demonstrated a favorable safety profile and efficient immune responses including IgG response, neutralizing antibodies and T-cell responses that parallel the activity of commercial vaccines following intramuscular (IM) administration of novel vaccine compositions expressing a single viral antigen. In addition, vector development has shown promise of neutralizing activity against a range of SARS-CoV-2 variants. Imunon’s DNA-based vaccines have been based on a simple intramuscular injection that does not require viral encapsulation or special equipment for administration.
In April 2022, the Company presented its PLACCINE platform technology at the 2022 World Vaccine Congress in an oral presentation during a Session on Cancer and Immunotherapy. The presentation entitled: “Novel DNA Approaches for Cancer Immunotherapies and Multivalent Infectious Disease Vaccines” highlighted the Company’s technology platform.
PLACCINE has demonstrated the potential to be a powerful platform that provides for rapid design capability for targeting two or more different variants of a single virus in one vaccine. There is a clear public health need for vaccines today that address more than one strain of viruses, like COVID-19, which have fast evolving variant capability to offer the widest possible protection. Murine model data has thus far been encouraging and suggests that the Company’s approach provides not only flexibility, but also the potential for efficacy comparable to benchmark COVID-19 commercial vaccines with durability to protect for more than six months.
In September 2022, the Company provided an update on the progress made in the development of a DNA-based vaccine using its PLACCINE platform technology. The Company reported evidence of IgG, neutralizing antibody, and T-cell responses to its SARS-CoV-2 PLACCINE vaccines in normal mice. In this murine model, the Company’s multivalent PLACCINE vaccine targeted against two different variants showed to be immunogenic as determined by the levels of IgG, neutralizing antibodies, and T-cell responses. Additionally, our multivalent vaccine was equally effective against two different variants of the COVID-19 virus while the commercial mRNA vaccine appeared to have lost some activity against the newer variant.
Final data from its now completed proof-of-concept (“PoC”) mouse challenge study confirmed that a PLACCINE DNA-based vaccine can produce robust levels of IgG, neutralizing antibodies, and T-cell responses. The data demonstrated the ability of the Company’s PLACCINE vaccine to protect a SARS-CoV-2 mouse model in a live viral challenge. In the study, mice were vaccinated with a PLACCINE vaccine expressing the SARS-CoV-2 spike antigen from the D614G variant or the Delta variant, or a combination vaccine expressing both the D614G and Delta spike variants. The vaccination was administered by intramuscular injection on Day 0 and Day 14, followed by challenge with live SARS-CoV-2 virus on Day 42. All three vaccines, including the single and dual antigen vaccines, were found to have a favorable safety profile and elicited IgG responses and inhibited the viral load by 90-95%. The dual antigen vaccine was equally effective against both variants of the SARS CoV-2 virus.
In October 2022, the Company reported partial results from an ongoing non-human primate study designed to examine the immunogenicity of its proprietary PLACCINE vaccine which supported PLACCINE as a viable alternative to mRNA vaccines. The study examined a single plasmid DNA vector containing the SARS-CoV-2 Alpha variant spike antigen formulated with a synthetic DNA delivery system and administered by intramuscular injection. In the study, Cynomolgus monkeys were vaccinated with the PLACCINE vaccine or a commercial mRNA vaccine on Day 1, 28 and 84. Analysis of blood samples for IgG and neutralizing antibodies showed evidence of immunogenicity both in PLACCINE and mRNA vaccinated subjects. Analysis of bronchoalveolar lavage for viral load by quantitative PCR showed viral clearance by >90% of the non-vaccinated controls. Viral clearance from nasal swab followed a similar pattern in a majority of vaccinated animals and a similar clearance profile was observed when viral load was analyzed by the tissue culture infectious dose method.
In March 2023, the Company announced final results from the NHP study involving three vaccine-treated non-human primates. The final data were consistent with the earlier data and showed excellent immunological response and viral clearance. More specifically, in this NHP study, we examined PLACCINE activity against a more advanced SARS-CoV-2 variants and at a DNA dose that was not previously tested in NHP and demonstrated robust IgG responses, neutralizing antibody responses and complete clearance of virus following the challenge as seen in the previous study.
In March 2023, the Company filed with the FDA a pre-IND package in advance of beginning human testing of a SARS-CoV-2 seasonal booster vaccine. In July 2023, the FDA confirmed in a written response our plug and play strategy agreeing that a platform approach to pre-clinical toxicology testing with reference to updated SARS-CoV-2 genes that align with current variant of concern may be used without additional need for toxicology studies. This demonstrated the flexibility and versatility of our platform, which allows for the rapid production and development of any vaccine by simply changing the antigen coding cassette.

On April 18, 2024, the Company announced that it received clearance from the FDA to begin a Phase I clinical trial with a seasonal COVID-19 booster vaccine. The Company filed an Investigational New Drug (IND) application for IMNN-101 in late February. The primary objectives of the Phase I study were to evaluate safety, tolerability, neutralizing antibody response, and the vaccine’s durability (duration of immunogenicity) in healthy adults. Secondary objectives of the study included evaluating the ability of the IMNN-101 vaccine to elicit binding antibodies and cellular responses and their associated durability. The Phase I study enrolled 24 subjects to evaluate three escalating doses of IMNN-101. For this study, IMMN-101 has been designed to protect against the SARS-CoV-2 Omicron XBB1.5 variant, in accordance with the FDA’s Vaccines and Related Biological Products Advisory Committee’s June 2023 announcement of the framework for updated COVID-19 doses.
In February 2025, the Company announced topline safety and immunogenicity data from ongoing analyses of results from the Company’s Phase 1 proof-of-concept clinical trial of IMNN-101. The Phase 1 study was conducted in 24 healthy volunteers as a seasonal COVID-19 vaccine, targeting the SARS-CoV-2 Omicron XBB1.5 spike antigen. IMNN-101 was administered as a single dose vaccine without a booster dose in study participants who were previously vaccinated against the Omicron XBB1.5 variant. Results demonstrated that IMNN-101 is safe and well-tolerated with no serious adverse effects. IMNN-101 induced a persistent 2- to 4-fold increase in serum neutralizing antibody (NAb) titers from baseline through Week 4, further increasing NAb titers between Week 2 and Week 4. The immune response was observed against the XBB1.5 variant and many newer variants following treatment, demonstrating the IMNN-101 vaccine’s cross-reactivity.
On May 15, 2025, the Company announced new data from its first Phase 1 proof-of-concept clinical trial of IMNN-101. Results in 24 healthy volunteers demonstrated IMNN-101’s durability of protection at six months after a single dose targeting the SARS-CoV-2 Omicron XBB1.5 spike antigen variant. IMNN-101 induced up to a 3-fold median increase in the serum neutralizing antibody (NAb) titers from baseline at six months, with initial evidence of a stronger immune response in two higher dose cohorts (2.0 mg and 1.0 mg) compared to a lower dose cohort (0.5 mg). The highest observed increase among the participating volunteers was 8-fold from baseline. IMNN-101 continues to be safe and well tolerated, with no serious adverse effects reported.
In the Phase 1 trial, designed to demonstrate the advantages of Imunon’s technology compared to approved messenger RNA (mRNA) vaccines, IMNN-101 was administered as a single dose vaccine without a booster dose in study participants who were previously vaccinated against the Omicron XBB1.5 variant. Study participants had high baseline immune characteristics, presumably from prior infection and multiple previous vaccinations against COVID-19, and ongoing infection. Modest increases in T-cell responses were observed in trial participants who received multiple immunizations prior to the study. Results from the Phase 1 trial build on data previously announced in February 2025, which showed IMNN-101 induced a persistent 2- to 4-fold increase in serum NAb titers from baseline through Week 4, further increasing NAb titers between Week 2 and Week 4. The immune response was also observed against the XBB1.5 variant and many newer variants following treatment, demonstrating the IMNN-101 vaccine’s cross-reactivity. The Phase 1 clinical data of IMNN-101 is consistent with strong evidence of immunogenicity and protection for the PlaCCine platform in rodents and non-human primates, with prior preclinical results showing comparable protection efficiency (>95%) to a commercial mRNA vaccine in non-human primates.
The Phase I trial was designed to establish proof of concept (PoC) for IMNN-101 as an advancement in vaccine technology. Imunon intends to seek partnership and/or business development opportunities to develop the scientific and business case for IMNN-101 as a future vaccine to address viral mutations. The Company has paused further development of this study at the current time.
Business Plan and Going Concern Risk
We have not generated and do not expect to generate any revenue from product sales in the next several years, if at all. An element of our business strategy has been to pursue, as resources permit, the research and development of a range of drug candidates for a variety of indications. We may also evaluate licensing products from third parties to expand our current product pipeline. This is intended to allow us to diversify the risks associated with our research and development expenditures. To the extent we are unable to maintain a broad range of drug candidates, our dependence on the success of one or a few drug candidates would increase and would have a more significant impact on our financial prospects, financial condition, and market value. We may also consider and evaluate strategic alternatives, including investment in, or acquisition of, complementary businesses, technologies, or products. Drug research and development is an inherently uncertain process and there is a high risk of failure at every stage prior to approval. The timing and the outcome of clinical results are extremely difficult to predict. The success or failure of any preclinical development and clinical trial can have a disproportionately positive or negative impact on our results of operations, financial condition, prospects, and market value.

Our current business strategy includes the possibility of entering into collaborative arrangements with third parties to complete the development and commercialization of our drug candidates. In the event that third parties are contracted to manage the clinical trial process for one or more of our drug candidates, the estimated completion date would largely be under the control of that third party rather than us. We cannot forecast with any degree of certainty which proprietary products or indications, if any, will be subject to future collaborative arrangements, in whole or in part, and how such arrangements would affect our development plan or capital requirements. We may also apply for subsidies, grants or government or agency-sponsored studies that could reduce our development costs. However, we cannot forecast with any degree of certainty whether we will be selected to receive any subsidy, grant or governmental funding.
As of March 31, 2026, the Company had $4.8 million in cash and cash equivalents to fund its operations. The Company’s primary sources of cash have been proceeds from the issuance and sale of its common stock, including via its at-the-market (“ATM”) program and other potential funding transactions. There can be no assurance that the Company will be able to do so in the future on a timely basis on terms acceptable to the Company, or at all. The Company has not yet commercialized any of its product candidates. Even if the Company commercializes one or more of its product candidates, it may not become profitable in the near term. The Company’s ability to achieve profitability depends on several factors, including its ability to obtain regulatory approval for its product candidates, successfully complete any post-approval regulatory obligations and successfully commercialize its product candidates alone or in partnership.
Such conditions raise substantial doubts about the Company’s ability to continue as a going concern. Based on the above, management has determined there is substantial doubt regarding our ability to continue as a going concern. The report of our independent registered public accounting firm for the year ended December 31, 2025, includes an explanatory paragraph which expresses substantial doubt about our ability to continue as a going concern. See also Note 2 to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.
Management’s plan includes raising funds from outside investors through the issuance and sale of its common stock, including the use of its at-the-market (“ATM”) program and other potential funding transactions. However, as mentioned above, there is no assurance such funding will be available to the Company or that it will be obtained on terms favorable to the Company or will provide the Company with sufficient funds to meet its objectives. The Company’s financial statements do not include any adjustments relating to the recoverability and classification of assets, carrying amounts or the amount and classification of liabilities that may be required should the Company be unable to continue as a going concern.
As a result of the risks and uncertainties discussed in the 2025 Annual Report filed on March 31, 2026 with the SEC, among others, we are unable to estimate the duration and completion costs of our research and development projects or when, if ever, and to what extent we will receive cash inflows from the commercialization and sale of a product if one of our drug candidates receives regulatory approval for marketing, if at all. Our inability to complete any of our research and development activities, preclinical studies or clinical trials in a timely manner or our failure to enter into collaborative agreements when appropriate could significantly increase our capital requirements and could adversely impact our liquidity. While our estimated future capital requirements are uncertain and could increase or decrease as a result of many factors, including the extent to which we choose to advance our research and development activities, preclinical studies and clinical trials, or whether we are in a position to pursue manufacturing or commercialization activities, we will need significant additional capital to progress our drug candidates through development and clinical trials, obtain regulatory approvals and manufacture and commercialize approved products, if any. We do not know whether we will be able to access additional capital when needed or on terms favorable to us or our stockholders. Our inability to raise additional capital, or to do so on terms reasonably acceptable to us, would jeopardize the future success of our business.
Financing Overview
Equity, Debt and Other Forms of Financing
During 2025 and for the three months ending March 31, 2026, we issued a total of 3.2 million shares of common stock as discussed below for approximately $14.9 million in net proceeds. Subsequent to March 31, 2026 and through the date of this Quarterly Report on Form 10-Q, we issued another 146,354 shares of common stock under the at-the-market (“ATM”) program for net proceeds of $417,447.
On May 15, 2024, the Company filed with the SEC a shelf registration statement on Form S-3 (the “2024 Registration Statement”) for the offer and sale of up to $75 million of its securities. The 2024 Registration Statement was declared effective on May 22, 2024. The 2024 Registration Statement is intended to provide the Company with flexibility to raise capital in the future for general corporate purposes. As noted in the prospectus supplement that the Company filed on July 22, 2025, the aggregate market value of our outstanding Common Stock held by non-affiliates was approximately $79,075,969, based on 2,121,895 shares of Common Stock outstanding as of July 22, 2025, of which 2,100,291 shares were held by non-affiliates, and a price of $37.65 per share, which was the last reported sale price of our Common Stock on The Nasdaq Stock Market LLC (“Nasdaq”) on June 2, 2025. As a result, our public float increased above $75.0 million, and we were no longer subject to the limitations contained in General Instruction I.B.6 of Form S-3. Upon the filing of the Form 10-K on March 31, 2026, the Company’s public float was less than $75.0 million, and as a result, the Company is currently subject to the limitations contained in General Instruction I.B.6 of Form S-3.

Significant Accounting Policies
Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements included in our 2025 Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 31, 2026. See Note 3 to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.
As a clinical-stage biopharmaceutical company, our business, and our ability to execute our strategy to achieve our corporate goals are subject to numerous risks and uncertainties. Material risks and uncertainties relating to our business and our industry are described in “Item 1A. Risk Factors” under “Part II: Other Information” included herein.
FINANCIAL REVIEW FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025
Results of Operations
For the three months ended March 31, 2026, our net loss was $4.3 million compared to a net loss of $4.1 million for the same three-month period of 2025.
With $4.8 million in cash and cash equivalents at March 31, 2026, such conditions raise substantial doubts about the Company’s ability to continue as a going concern. Based on the above, management has determined there is substantial doubt regarding our ability to continue a going concern.
Management’s plan includes raising funds from the issuance and sale of its common stock via its ATM program and other funding transactions. However, as mentioned above, there is no assurance such funding will be available to the Company or that it will be obtained on terms favorable to the Company or will provide the Company with sufficient funds to meet its objectives. The Company’s financial statements do not include any adjustments relating to the recoverability and classification of assets, carrying amounts or the amount and classification of liabilities that may be required should the Company be unable to continue as a going concern.
The Company operates in one segment for the research and development of our product candidates. The Company’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer and President, who reviews operating results to make decisions about allocating resources and assessing performance for the entire Company based on consolidated financial information. Consequently, we view the entire organization as one reportable segment and the strategic purpose of all operating activities (including general & administrative expenses) is to support that one segment. As a pre-revenue research and development company, the CODM evaluates company-wide performance and allocates resources based on non-financial research and development milestones achieved, and to a lesser extent, financial measures of performance such as clinical development (research and development expenses) and general and administrative expenses incurred. Our CODM does not generally evaluate our performance using asset or historical cash flow information.

Research and Development Expenses
Research and development (“R&D”) expenses increased to $2.3 million in the first quarter of 2026 from $2.2 million in the same period of 2025. Clinical costs associated with the OVATION 3 study was $0.1 million each of the first quarters of 2026 and 2025. Clinical costs associated with the OVATION 2 study was $0.1 million each of the first quarters of 2026 and 2025. During 2025, the Company initiated enrollment in the OVATION 3 Study and closed out the OVATION 2 study. Other clinical and regulatory costs remained relatively unchanged at $0.6 million in each of the first quarters of 2026 and 2025. R&D costs associated with the development of IMNN-001 to support the OVATION program were $1.3 million in the first quarter of 2026 compared to $0.9 million in same period of 2025. CMC costs were $0.2 million in the first quarter of 2026 compared to $0.4 million in the same period of 2025.
General and Administrative Expenses
General and administrative expenses remained relatively unchanged at $2.0 million in each of the first quarters of 2026 and 2025.
Investment income from the Company’s short-term investments was $58,000 for the first quarter of 2026 compared to $43,000 for the same period in 2025.
FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
Since inception, we have incurred significant losses and negative cash flows from operations. We have financed our operations primarily through the net proceeds from the sales of equity, credit facilities and amounts received under product licensing agreements. The process of developing IMNN-001 and other drug candidates and technologies requires significant research and development work and clinical trial studies, as well as significant manufacturing and process development efforts. We expect these activities, together with our general and administrative expenses, to result in significant operating losses for the foreseeable future. Our expenses have significantly and regularly exceeded our income, and we had an accumulated deficit of $426 million at March 31, 2026.
At March 31, 2026, we had total current assets of $6.2 million and current liabilities of $4.2 million, resulting in net working capital of $2.0 million. At March 31, 2026, we had cash and cash equivalents of $4.8 million. At December 31, 2025, we had total current assets of $10.7 million and current liabilities of $4.6 million, resulting in net working capital of $6.1 million. We have substantial future capital requirements to continue our research and development activities and advance our drug candidates through various development stages. The Company believes these expenditures are essential for the commercialization of its technologies.
Net cash used in operating activities for the first three months of 2026 was $4.0 million. Net cash associated with investing activities was insignificant during the first three months of 2026.
The Company will continue to seek additional capital through further public or private equity offerings, debt financing, additional strategic alliance and licensing arrangements, collaborative arrangements, or some combination of these financing alternatives. If we raise additional funds through the issuance of equity securities, the percentage ownership of our stockholders could be significantly diluted, and the newly issued equity securities may have rights, preferences, or privileges senior to those of the holders of our common stock. If we raise funds through the issuance of debt securities, those securities may have rights, preferences, and privileges senior to those of our common stock. If we seek strategic alliances, licenses, or other alternative arrangements, such as arrangements with collaborative partners or others, we may need to relinquish rights to certain of our existing or future technologies, drug candidates, or products we would otherwise seek to develop or commercialize on our own, or to license the rights to our technologies, drug candidates, or products on terms that are not favorable to us. The overall status of the economic climate could also result in the terms of any equity offering, debt financing, or alliance, license, or other arrangement being even less favorable to us and our stockholders than if the overall economic climate were stronger. We also will continue to look for government sponsored research collaborations and grants to help offset future anticipated losses from operations and, to a lesser extent, interest income.
If adequate funds are not available through either the capital markets, strategic alliances, or collaborators, we may be required to delay or, reduce the scope of, or terminate our research, development, clinical programs, manufacturing, or commercialization efforts, or effect additional changes to our facilities or personnel, or obtain funds through other arrangements that may require us to relinquish some of our assets or rights to certain of our existing or future technologies, drug candidates, or products on terms not favorable to us.
Such conditions raise substantial doubts about the Company’s ability to continue as a going concern. Management’s plan includes raising funds from the issuance and sale of its common stock via its ATM program and other funding transactions. However, as mentioned above, there is no assurance such funding will be available to the Company or that it will be obtained on terms favorable to the Company or will provide the Company with sufficient funds to meet its objectives. The Company’s financial statements do not include any adjustments relating to the recoverability and classification of assets, carrying amounts or the amount and classification of liabilities that may be required should the Company be unable to continue as a going concern.

None.
Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item.
Item 4. CONTROLS AND PROCEDURES
We have carried out an evaluation, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as that term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended. Based on that evaluation, our principal executive officer and principal financial officer have concluded that, as of March 31, 2026, which is the end of the period covered by this report, our disclosure controls and procedures are effective at the reasonable assurance level in alerting them in a timely manner to material information required to be included in our periodic reports with the SEC.
There were no changes in our internal control over financial reporting identified in connection with the evaluation that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
