Independent Data Monitoring Committee recommends the ongoing Phase 2 MRD study continue without modification following its review of all safety data to date

No cytokine release syndrome, systemic toxicities or serious immune-related adverse events observed to date, reinforcing IMNN-001's differentiated safety profile as an IL-12-based immunotherapy

MRD study has now demonstrated the safety and tolerability of IMNN-001 both in combination with bevacizumab and in the maintenance setting

Recommendation follows encouraging preliminary Phase 2 MRD data reported in July demonstrating evidence of deeper anti-tumor activity and immune activation

LAWRENCEVILLE, N.J., Sept. 22, 2026 (GLOBE NEWSWIRE) -- IMUNON, Inc. (NASDAQ:IMNN), a clinical-stage biotechnology company developing DNA-mediated immunotherapies, today announced that the Independent Data Monitoring Committee (IDMC) overseeing its ongoing Phase 2 minimal residual disease (MRD) translational study of IMNN-001 has reviewed all safety data to date and recommended that the study continue without modification after identifying no new safety signals and confirming comparable safety across both treatment arms.

The IDMC is comprised of independent medical experts in gynecologic cancers. The Phase 2 MRD study is a randomized, controlled translational study assessing minimal residual disease following treatment with standard-of-care chemotherapy and bevacizumab, with or without IMNN-001, in women with newly diagnosed advanced ovarian cancer. The multi-site study is being conducted in collaboration with Break Through Cancer and is led by investigators at The University of Texas MD Anderson Cancer Center.
