OVATION 3 Study
OVATION 3 Study.***On September 11, 2024, a scientific advisory board was held with DSMB members, principal investigators, and scientific experts to discuss and seek input on the protocol synopsis for the Phase III trial. A protocol synopsis was submitted along with a briefing document for review and input at the End-of-Phase II (“EOP2”) meeting with the U.S. Food and Drug Administration focused on the Phase III study. The EOP2 meeting was conducted in the fourth quarter of 2024.
| ● | The positive outcome of the EOP2 in-person meeting with the U.S. Food and Drug Administration (FDA), supported the advancement of IMNN-001 for the treatment of advanced ovarian cancer into a Phase 3 pivotal study. The interaction with the FDA included an extensive review of data generated to date, including positive results from the recently completed Phase 2 OVATION 2 Study, which assessed IMNN-001 (100 mg/m2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin compared to standard-of-care NACT alone in 112 patients with newly diagnosed advanced ovarian cancer. Treatment was also generally well tolerated, with no reports of cytokine release syndrome or any other serious immune-related adverse events. |
| ● | The Company also held a Type C Chemistry, Manufacturing, and Controls (CMC) meeting with the FDA regarding production of IMNN-001 for the treatment of women with newly diagnosed advanced ovarian cancer. The goal of the meeting was to seek alignment and agreement with the FDA on key CMC topics to support IMNN-001 production for the planned Phase 3 pivotal trial and a potential future new biologic license application (BLA) submission. The meeting with the FDA included a review of the Company’s current good manufacturing practice (cGMP) clinical-scale and commercial manufacturing process for IMNN-001, conducted at the company’s manufacturing facility based in Huntsville, Alabama. The Agency agreed that the Company’s potency assay which measures interferon-gamma (IFN-γ) is acceptable for the Phase 3 clinical study and for use in a commercial setting for release of drug product. The FDA also agreed with the Company’s strategy to establish comparability of the core components of IMNN-001 produced by the Company with product previously produced through an external contract development and manufacturing organization. |
The Phase 3 OVATION 3 trial will assess the safety and efficacy of IMNN-001 (100 mg/m 2 administered intraperitoneally weekly) plus neoadjuvant and adjuvant chemotherapy (NACT) of paclitaxel and carboplatin compared to standard of care (SoC) NACT alone. Study participants are being randomized 1:1 and include women with newly diagnosed advanced ovarian cancer (stage 3 or 4) who are eligible for neoadjuvant therapy, the intent-to-treat (ITT) population, with a sub-group of women positive for homologous recombination deficiency (HRD) including BRCA1 or BRCA2 mutations. Participants who are HRD positive will receive poly (ADP-ribose) polymerase (PARP) inhibitors as part of standard maintenance therapy. The primary endpoint of the study is overall survival (OS), and secondary endpoints are surgical response score, chemotherapy response score, clinical response and time to second-line treatment. The study will also assess several exploratory endpoints.
In March 2025, the Company announced that the FDA is aligned with the protocol for the Phase 3 OVATION 3 pivotal trial of its lead candidate IMNN-001 in development for the treatment of women with newly diagnosed advanced ovarian cancer. The Company is currently enrolling patients at four trial sites with additional sites being considered for activation.
As of December 31, 2025, four sites are open to recruitment, Providence Sacred Heart Medical Center & Children’s Hospital, Washington University School of Medicine in St. Louis, Providence Cancer Institute in Portland, and Erlanger Health in Chattanooga with up to 46 additional sites being considered for activation. As of December 31, 2025, enrollment in the ITT population remains ahead of forecast.
