Replimune receives complete response letter from the FDA for RP1 biologics license application for the treatment of advanced melanoma
10 April 2026 - Replimune Group today announced that the company received a complete response letter from the US FDA for the Company’s biologics license application for RP1 in combination with nivolumab for the treatment of advanced melanoma.
Replimune disagrees with the FDA about whether the data set, upon which breakthrough therapy designation was awarded, is sufficient to allow this promising medicine to be made available to advanced cancer patients. In the IGNYTE trial, patients with confirmed progression on an anti-PD-1 based regimen who received RP1 plus nivolumab had a 34% response rate with a median duration of 24.8 months with a favourable safety profile.
