"Enrollment in our pivotal Phase 3 OVATION 3 trial continues ahead of plan, reflecting patient interest and strong conviction among principal investigators and the broader medical community in IMNN-001’s therapeutic potential," said Stacy Lindborg, Ph.D., President and Chief Executive Officer of IMUNON. "Coupled with the unprecedented overall survival benefit observed in our Phase 2 (OVATION 2) study and an aligned path to BLA filing, IMNN-001 is well positioned to potentially transform the standard of care in advanced ovarian cancer."

RECENT DEVELOPMENTS

Final Phase 2 OVATION 2 Study Data Show Continued Overall Survival Improvement with IMNN-001 in Women with Newly Diagnosed Advanced Ovarian Cancer – 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 (N/ACT) in 112 women with newly diagnosed advanced ovarian cancer. IMUNON previously 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 most recent and 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 months delta). In addition, the new 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 new efficacy results, IMNN-001 continues to show a highly favorable safety and tolerability profile across all clinical trials, further reinforcing the potential of this IL-12 immunotherapy to represent a landmark advance in treatment of this disease.

IMUNON Sharpens Focus on its Promising Pivotal Phase 3 Ovarian Cancer Study – On February 5, 2026, the Company announced a strategic reorganization, the goal of which was to reduce operating expenses while supporting the Company’s focused strategy to rapidly advance the pivotal Phase 3 OVATION 3 clinical trial.
