Advisory Committee voted 10 to 3 that the efficacy results from the IGNYTE study are evaluable and clinically meaningfulWOBURN, Mass., July 30, 2026 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (Nasdaq: REPL), a clinical-stage biotechnology company pioneering the development of novel oncolytic immunotherapies, today announced the outcome of today's meeting of the U.S. Food and Drug Administration's (FDA) Cellular, Tissue, and Gene Therapies Advisory Committee (CTGTAC), which discussed the Biologics License Application (BLA) resubmission for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of advanced melanoma in patients who have progressed on prior anti-PD-1 therapy. The committee discussed two topics: (1) whether the single-arm IGNYTE study, as designed and conducted, allows for a reliable determination of the expected response rate and durability of response in the proposed population; and (2) the clinical meaningfulness of the response rate and duration of response reported in IGNYTE, and whether the observed responses are indicative of systemic antitumor activity attributable to RP1. The committee then voted 10 to 3, on the question: “Are the efficacy results from IGNYTE evaluable and clinically meaningful?” “We are encouraged by today's outcome and would like to thank the committee for its thoughtful discussion of the IGNYTE data,” said Sushil Patel, Ph.D., CEO of Replimune. “We are grateful to the patients and physicians who took the time to speak today and so clearly articulate the high unmet need in advanced melanoma and importance of new treatment options such as RP1 for the community. This is an important step forward for patients with advanced melanoma who have progressed on anti-PD-1 therapy. We look forward to continuing to work with the FDA as it completes its review of the BLA ahead of the action date.” The FDA's target action date under the Class 1 resubmission is August 2, 2026. About RP1 RP1 (vusolimogene oderparepvec) is Replimune’s lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response. About Replimune Replimune Group, Inc., headquartered in Woburn, MA, was founded in 2015 with the mission to transform cancer treatment by pioneering the development of novel oncolytic immunotherapies. Replimune’s proprietary RPx platform is based on a potent HSV-1 backbone intended to maximize immunogenic cell death and the induction of a systemic anti-tumor immune response. The RPx platform is intended to ignite local activity consisting of direct selective virus-mediated killing of the tumor resulting in the release of tumor derived antigens and altering of the tumor microenvironment to then activate a strong and durable systemic response. The RPx product candidates are expected to be synergistic with most established and experimental cancer treatment modalities, leading to the versatility to be developed alone or combined with a variety of other treatment options.
