IMUNON's IMNN-001: A Breakthrough in Ovarian Cancer Treatment

IMUNON, Inc. (NASDAQ: IMNN) has announced continued strong improvement in overall survival data from the randomized Phase 2 OVATION 2 Study of IMNN-001, its investigational interleukin-12 (IL-12) immunotherapy for the treatment of advanced ovarian cancer. The company's proprietary TheraPlas® technology enables the localized production and secretion of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. This innovative approach has shown promising results in enhancing the body's immune response to ovarian cancer when combined with standard-of-care chemotherapy.

The OVATION 2 Study, which enrolled 112 patients with newly diagnosed advanced ovarian cancer, demonstrated a significant improvement in overall survival (OS) and progression-free survival (PFS) for patients treated with IMNN-001 plus standard-of-care neoadjuvant and adjuvant chemotherapy (NACT) compared to standard-of-care NACT alone. The median OS increased from 11 to 13 months in the IMNN-001 treatment group, with a hazard ratio (HR) decreasing from 0.74 to 0.69. More than one-third of patients in the trial survived more than 36 months from the point of study enrollment, with 62% of those surviving patients from the IMNN-001 treatment arm and 38% from the standard-of-care arm. Over 10% of trial participants have reached 48 months or beyond.

Maintenance therapies, such as PARP inhibitors, play a crucial role in sustaining the improvement of overall survival in patients treated with IMNN-001. In the OVATION 2 study, patients who received a PARP inhibitor as maintenance therapy in the IMNN-001 treatment arm had a median PFS of 33.8 months versus 22.1 months in the control arm, and median OS was not reached for the treatment arm versus 37.1 months for the control arm.

IMNN-001 demonstrated a favorable safety profile in the Phase 2 OVATION 2 Study, with no reports of serious immune-related adverse events. The most common adverse events were primarily gastrointestinal events, which were effectively managed with pain management protocols. This compares favorably to other treatments in its class, such as checkpoint inhibitors, which can cause more severe immune-related side effects.

The long-term benefits and risks associated with IMNN-001 therapy are promising. With a median overall survival increase from 11 to 13 months in the treatment group and no serious immune-related adverse events reported, IMNN-001 could significantly improve outcomes for advanced ovarian cancer patients. However, risks include potential long-term side effects and the need for further clinical validation.

IMUNON remains on track to initiate a Phase 3 pivotal trial of IMNN-001 in Q1 2025, following an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) in person to discuss the design for the Phase 3 study. The company's lead clinical program, IMNN-001, has shown great promise in the treatment of advanced ovarian cancer, and investors should closely monitor its progress as it moves towards commercialization.
