The FDA accepted Replimune’s BLA resubmission for RP1 plus nivolumab in advanced melanoma. The agency set an April 10, 2026 PDUFA date under a Class II resubmission timeline.
The U.S. Food and Drug Administration has accepted the resubmission of the Biologics License Application for RP1 in combination with nivolumab for the treatment of advanced melanoma in patients who progress on an anti-PD-1 containing regimen. The PDUFA date set by the FDA is April 10, 2026 based on a Class II resubmission timeline.
During the past few months, Replimune has been working to address agency feedback. Additional information, data and analyses were included in the resubmission which will be part of the BLA review. The FDA indicated this resubmission is considered to be a complete response to the complete response letter received in July 2025.
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.
The company said existing cash, cash equivalents, and short-term investments of $269.1 million will provide cash runway late into the first quarter of calendar 2027.
