Insights

Phase 3 progress and supportive translational data contrast with a tight cash runway into Q1 2026.

IMUNON advances its Phase 3 OVATION 3 program with strong translational signals and reported survival benefit signals from OVATION 2, which the company highlights as a mechanistic shift of the tumor microenvironment from “cold” to “hot.” The company presented consistent biomarker and tolerability data across multiple scientific meetings, described enrollment exceeding expectations, and noted a well‑precented, adaptive Phase 3 design aligned with the FDA.

Financially, operating discipline reduced operating expenses by 30% year‑over‑year and net loss narrowed to $3.4 million in Q3 2025, improving nine‑month results vs prior year. However, cash and cash equivalents of $5.3 million, and a stated funding horizon into Q1 2026, create a near‑term financing dependency. The company received $4.5 million of proceeds in Q3 from warrants and ATM activity and is pursuing selective financing to support the pivotal trial.

Key dependencies and risks are explicit: continued OVATION 3 enrollment and maintenance of the regulatory alignment described, availability of capital before Q1 2026, and confirmation that Phase 2 signals translate at the pivotal scale. Watch for enrollment pace updates, any announced interim analysis timing, and near‑term financing outcomes within the next 3–6 months.

R&D Day showcased remarkable Investigator optimism, continued strengthening supportive data, and significant progress with Phase 3 OVATION 3 Study in pursuit of first frontline immunotherapy for advanced ovarian cancer

Company to hold conference call today at 11:00 a.m. ET

LAWRENCEVILLE, N.J., Nov. 13, 2025 (GLOBE NEWSWIRE) -- IMUNON, Inc. (Nasdaq: IMNN), a clinical-stage company in Phase 3 development with its DNA-mediated immunotherapy, today reported financial results for the three-month and nine-month periods ended September 30, 2025, and highlighted recent business updates, including progress in advancing Phase 3 clinical development of its lead candidate IMNN-001 in newly diagnosed advanced ovarian cancer.

IMUNON is rapidly advancing a potential breakthrough for women with newly diagnosed advanced ovarian cancer—a disease with no meaningful frontline treatment progress in decades,” said Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON. “Strong Phase 2 OVATION 2 survival data, reinforced by compelling interim results from our MRD study and a clear regulatory path in Phase 3, position IMNN-001 to deliver transformative impact.”

We have taken steps to conserve cash and align our critical needs with available capital on hand, while securing the resources needed to advance this potentially transformative therapy with select financing opportunities,” Dr. Lindborg continued.

RECENT DEVELOPMENTS

IMNN-001 Immunotherapy

R&D Day Highlighting Progress on OVATION 3 Study in Pursuit of First Frontline Immunotherapy for Advanced Ovarian Cancer – On November 10, 2025, the Company hosted an R&D Day, providing updates on new IMNN-001 data and discussing progress with the OVATION 3 Study and IMNN-001’s potential role in transforming the treatment landscape for women with advanced ovarian cancer. The event featured ovarian cancer thought leaders, principal investigators from the Company’s Phase 3 OVATION 3 Study and Phase 2 minimal residual disease (MRD) clinical trial (conducted in partnership with Break Through Cancer Foundation), and statistical experts.

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 also 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 remarkable 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.
  • 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 shows 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 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 an interim analysis of overall survival. This foundation, supported by conservative power assumptions drawn from Phase 2 data, strong simulation modeling and robust statistical properties, underpins the Phase 3 trial's high probability for success.

  • Douglas V. Faller, M.D., Ph.D., IMUNON, shared new data further demonstrating 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.

The presentations from the R&D Day are available on the “Scientific Presentations” page of the IMUNON’s website at https://investors.imunon.com/scientific-presentations

IMUNON Presents Translational Data from Phase 2 OVATION 2 Study of IMNN-001 at SITC 40th Annual Meeting – On November 7, 2025, the Company presented translational data from the Phase 2 OVATION 2 clinical trial of IMNN-001 at the Society for Immunotherapy of Cancer (SITC) 40th Annual Meeting, held on November 5-9, 2025 in National Harbor, Maryland.

The new data from recently analyzed OVATION 2 samples demonstrated that IMNN-001 creates a “hot” anti-tumor microenvironment in epithelial ovarian cancer by (i) increasing the recruitment of anti-tumor CD8+, myeloid dendritic cells and M1 macrophages in patient tumors; and (ii) decreasing immunosuppressive markers (IDO, Treg, exhausted CD8, M2 macrophages). These results, including induction of favorable ratios of CD8+/Tregs and CD8+/CD4+ cells, which are both associated with improved patient outcomes, are consistent with the results of the previous OVATION 1 study and with the efficacy seen in the clinic in the OVATION 2 study. This biomarker research confirms local immune activation at the tumor site by IMNN-001.

IMUNON Presents Phase 3 OVATION 3 Study of IMNN-001 in Advanced Ovarian Cancer at the ESMO Congress and the IGCS 2025 Annual Global Meeting – On October 14, 2025, the Company announced that a trials-in-progress abstract on the ongoing Phase 3 OVATION 3 clinical trial of IMNN-001 was presented at the European Society for Medical Oncology (ESMO) Congress 2025, held on October 17-21, 2025 in Berlin, Germany with an encore presentation following the 2025 Annual Global Meeting of the International Gynecologic Cancer Society (IGCS), held on November 5-7, 2025, in Cape Town, South Africa. The poster presentations are available on the “Scientific Presentations” page of the IMUNON’s website at https://investors.imunon.com/scientific-presentations

Positive Translational Data of IMNN-001 Presented at AACR Special Conference in Cancer Research Demonstrating 13 Month OS Extension via Tumor Micro-Environment Shift – On September 22, 2025, the Company presented positive translational data from the Phase 2 OVATION 2 Study of IMNN-001 at the American Association for Cancer Research (AACR) Special Conference in Cancer Research: Advances in Ovarian Cancer Research, held on September 19-21, 2025, in Denver, Colorado 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.

IMUNON reviewed translational data on the changes induced by the local administration of IL-12 and its downstream effectors in the tumor micro-environment (TME) from paired samples (pre- and post-treatment) from study participants. 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.

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. IMNN-001 has shown significant therapeutic potential in clinical trials thus far, and the robust survival benefits and favorable safety profile observed align with these translational findings, supporting the ongoing Phase 3 OVATION 3 trial.

PlaCCine® DNA Vaccine Technology

PlaCCine® DNA Technology Proof-of-Concept Data Presented in Platform Presentations at Leading Vaccine Conferences – On October 17, 2025, the Company announced that members of its leadership team will deliver oral presentations highlighting IMNN-101, its investigational DNA plasmid vaccine based on the Company’s proprietary PlaCCine® technology platform, including proof-of-concept clinical trial results at the following vaccine conferences:

  • 5th Edition of International Vaccines Congress (IVC) Keynote Oral Presentation Title: A promising novel approach to DNA vaccines, on October 23 2025 and
  • 10th International Conference on Vaccine Research and Development Oral Presentation Title: Development of a PlaCCine DNA Technology for Safe, Effective and Durable Vaccines, on November 6, 2025

These presentations described the unique design and composition of the PlaCCine technology and its differentiating features including a longer duration of antigen expression, safety, user compliance and storage stability at workable temperatures (up to one year at 4°C and one month at 37°C) in comparison to mRNA vaccines and other DNA vaccines requiring viruses or devices for delivery. The immunogenicity of the PlaCCine technology was demonstrated against various pathogens in multiple species and animal models. These presentations also demonstrated safety and immunogenicity of a PlaCCine vaccine targeting a SARS-CoV-2 spike variant in healthy human participants following intramuscular administration. Durable NAb responses to 6 months demonstrating vaccine immunogenicity following a single dose in previously vaccinated or infected individuals with the SARS-CoV-2 underscore the significance of the PlaCCine approach and support continued development in both naive populations using a prime and boost vaccination to determine optimal benefits and in other infectious diseases.

IMNN-101 has been shown to be safe and well tolerated, with no serious adverse effects reported. To accelerate the development and commercialization of the PlaCCine platform, IMUNON is actively seeking strategic partnerships with leading pharmaceutical and biotechnology companies. These collaborations aim to leverage PlaCCine’s unique advantages—enhanced durability, temperature stability, and scalable manufacturing—to address unmet needs in vaccines for infectious diseases and cancer, while securing non-dilutive funding to advance IMUNON’s broader oncology focused pipeline
