WOBURN, Mass., Sept. 18, 2025 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (NASDAQ: REPL), a clinical stage biotechnology company pioneering the development of novel oncolytic immunotherapies, today announced that the company completed a Type A meeting with the U.S. Food and Drug Administration (FDA) on September 16^thto discuss the complete response letter (CRL) for the Company’s Biologics License Application (BLA) for RP1 in combination with nivolumab for the treatment of advanced melanoma.

The company is evaluating the feedback from the FDA provided during the meeting to determine next steps. At this time, a path forward under the accelerated approval pathway has not been determined.

“The feedback from the melanoma community, including patients and physicians, clearly highlights the unmet need in advanced melanoma and the compelling risk-benefit profile of RP1 observed in the IGNYTE trial,” said Sushil Patel, Ph.D., CEO of Replimune. “We remain committed to working with the FDA to determine an expeditious path forward for RP1.”

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.
