IMUNON, Inc. Reports 2025 Financial Results and Major Clinical Progress in Ovarian Cancer Immunotherapy

Key Highlights for Investors

• IMNN-001 Shows Unprecedented Survival Benefit: Final Phase 2 OVATION 2 data reveals IMNN-001 delivers a median overall survival increase of 14.7 months (45.1 vs. 30.4 months) compared to standard-of-care (SoC) chemotherapy alone. When combined with PARP inhibitors, the overall survival benefit rises to 24.2 months (65.6 vs. 41.4 months).
• Phase 3 Enrollment Ahead of Plan: OVATION 3, the pivotal Phase 3 trial, is progressing faster than expected, driven by strong investigator and community interest.
• Favorable Safety and Tolerability Profile: IMNN-001 continues to demonstrate a highly favorable safety profile in both the Phase 2 and ongoing studies, reinforcing its potential as a landmark treatment for advanced ovarian cancer.
• Strategic Focus and Cost Reduction: IMUNON has executed a corporate reorganization to reduce operating expenses, focusing resources on rapid advancement of the OVATION 3 trial.
• Successful Financing: The company completed a \$7.0 million registered direct offering at-the-market under NASDAQ rules in December 2025 to bolster its cash position.
• Financial Performance: Net loss narrowed to \$14.5 million (\$6.83 per share) from \$18.6 million (\$16.94 per share) in 2024, with a 23% reduction in operating expenses and improved cash management.
• Innovative Vaccine Technology: PlaCCine® DNA vaccine platform demonstrates promising clinical results in SARS-CoV-2 (COVID-19) booster trials and shows potential for durable responses and broad applications.

Detailed Business Update

IMNN-001 Immunotherapy for Ovarian Cancer

IMUNON’s lead candidate, IMNN-001, is positioned as the first frontline immunotherapy with potential for a clinically meaningful overall survival benefit in women newly diagnosed with advanced ovarian cancer. The final Phase 2 OVATION 2 data, released in March 2026, shows continued improvement in median overall survival:

• IMNN-001 + SoC chemotherapy: Median OS of 45.1 months vs. 30.4 months for SoC alone—a 14.7 month increase.
• IMNN-001 + SoC chemotherapy + PARP inhibitors: Median OS of 65.6 months vs. 41.4 months for SoC alone—a 24.2 month increase.

These results mark a significant advance, especially given that frontline treatment options for ovarian cancer have seen little progress in the past 35 years. Additionally, IMNN-001 maintains a highly favorable safety and tolerability profile, critical for regulatory approval and patient adoption.

Phase 3 OVATION 3 Study Advancing Rapidly

OVATION 3, the pivotal Phase 3 trial, is enrolling ahead of plan. The trial design leverages an adaptive, event-driven approach similar to previous successful oncology trials, increasing the probability of regulatory success. Data from Phase 2 and ongoing MRD studies reinforce the benefit-risk profile and provide translational insights into IMNN-001’s mechanism—turning the tumor microenvironment from “cold” to “hot” and activating both innate and adaptive immunity.

Translational and Clinical Data Presented at Major Conferences

• SITC 40th Annual Meeting: New data confirmed IMNN-001 induces a “hot” anti-tumor microenvironment, increasing recruitment of anti-tumor CD8+, dendritic cells, and M1 macrophages, while decreasing immunosuppressive markers. Improved CD8+/Treg and CD8+/CD4+ ratios are linked to better patient outcomes.
• ESMO Congress and IGCS Global Meeting: Trials-in-progress abstracts on OVATION 3 trial presented, highlighting ongoing clinical momentum.

PlaCCine® DNA Vaccine Platform

IMUNON’s PlaCCine® platform is a proprietary DNA technology with proof-of-concept oral presentations at leading vaccine conferences. PlaCCine vaccines offer:

• Longer antigen expression durations
• Storage stability at workable temperatures (up to one year at 4°C, one month at 37°C)
• Safety and immunogenicity demonstrated in both animal models and human participants

IMNN-101, a SARS-CoV-2 variant-targeting vaccine, showed durable neutralizing antibody responses at six months post single dose in previously vaccinated or infected individuals. No serious adverse effects reported. Commercialization will require strategic partnership(s).

Financial Results and Corporate Actions

• Net Loss: \$14.5 million (\$6.83 per share) for 2025, improved from \$18.6 million (\$16.94 per share) in 2024.
• Operating Expenses: \$14.7 million, down 23% year-over-year, reflecting corporate reorganization and focus on OVATION 3.
• R&D Expenses: \$7.8 million, a 33% decrease mainly due to lower costs for OVATION 2 and PlaCCine trials.
• G&A Expenses: \$6.9 million, down 8%, due to headcount reductions.
• Cash Position: \$8.8 million as of December 31, 2025, up from \$5.9 million in 2024. Financing activities raised \$17.1 million during the year.
• Shares Outstanding: Weighted average shares increased to 2,123 thousand from 1,099 thousand in 2024, reflecting new offerings.

Strategic Outlook

IMUNON is sharply focused on advancing its pivotal Phase 3 OVATION 3 trial for IMNN-001. The company’s strategic reorganization and cost management aim to maximize resources for this potentially transformative therapy. The strength of the clinical and translational data, coupled with a clear regulatory path and favorable safety profile, position IMNN-001 as a breakthrough in ovarian cancer treatment. Investors should note that continued enrollment progress and positive interim Phase 3 data could be highly price-sensitive and move the share price, especially if regulatory milestones are achieved.

Upcoming Catalysts

• Interim and final data from OVATION 3 Phase 3 trial
• Potential regulatory submissions if Phase 3 results are positive
• Strategic partnerships for PlaCCine vaccine platform
• Further conference presentations and investor updates

Conclusion

IMUNON’s 2025 financial results and business update highlight significant progress in both clinical and corporate fronts. The company’s lead candidate, IMNN-001, is demonstrating clinically meaningful and unprecedented survival benefits in advanced ovarian cancer, with a strong safety profile and robust translational data. The pivotal Phase 3 trial is advancing rapidly, supported by a focused strategy and improved financial management. These developments represent multiple potential catalysts for share price movement, especially as Phase 3 data matures and regulatory milestones approach.
