  • Global Stage: IMUNON to present pivotal immune biomarker data for IMNN-001 at ESMO Gynaecological Cancers Congress 2025, spotlighting its innovative ovarian cancer therapy.
  • Unprecedented Survival: Phase 2 OVATION 2 study reveals remarkable extensions in patient survival, with some women gaining approximately 13 months in overall survival and nearly 12 months in progression-free survival6, 7.
  • New Dawn for Patients: IMNN-001 offers a beacon of hope for the estimated 300,000 women diagnosed globally each year with advanced ovarian cancer, a disease with grim survival rates6.

A wave of excitement is building in the oncology community as IMUNON prepares to showcase compelling translational data from its Phase 2 OVATION 2 study of IMNN-001 at the prestigious ESMO Gynaecological Cancers Congress 2025 in Vienna7. This follows an electrifying oral presentation at the 2025 ASCO Annual Meeting and a simultaneous, lauded publication in the leading journal Gynecologic Oncology, all underscoring the truly unprecedented survival benefits observed with this novel immunotherapy5, 6.

For women battling advanced ovarian cancer, where five-year survival rates remain devastatingly low, IMNN-001 is emerging as a potential game-changer. The OVATION 2 study demonstrated that IMNN-001, when combined with standard chemotherapy, led to a median increase of approximately 13 months in overall survival and a significant 3-month (up to nearly 12 months in some analyses) boost in progression-free survival compared to chemotherapy alone6, 7. These are not just statistics; they represent precious extended time for patients and their families.

IMNN-001, leveraging IMUNON’s proprietary TheraPlas® technology, is a DNA-based immunotherapy designed to locally unleash the power of interleukin-12 (IL-12) directly within the tumor microenvironment. This potent cytokine supercharges the body's own immune defenses, promoting T-lymphocyte and natural killer cell proliferation to fight the cancer6, 7. Impressively, it’s the first IL-12 immunotherapy to achieve such a clinically effective response, including an overall survival benefit in frontline treatment for advanced ovarian cancer, all while maintaining an outstanding safety profile8.

With the pivotal Phase 3 OVATION 3 trial now initiated, the global medical community watches with bated breath. "There is a significant opportunity to improve the standard of care for thousands of women," stated Stacy Lindborg, Ph.D., president and CEO of IMUNON, highlighting the strong international interest in this promising therapy7. The fight against ovarian cancer has a powerful new contender.
