On July 28, 2026, the U.S. Food and Drug Administration published briefing documents stating concerns about the data package that Replimune has offered to support accelerated approval for its drug RP1 (vusolimogene oderparepvec) in combination with Bristol Myers Squibb's PD-1 inhibitor Opdivo for adults with unresectable advanced cutaneous melanoma who experience disease progression after a PD-1-blocking antibody-based therapy. Specifically, the FDA's briefing documents said that the response assessment used in the Phase 1/2 IGNYTE study "confounds interpretation of the reported efficacy results and limits FDA's ability to verify the reported results". 

On this news, Replimmune's stock price fell $3.28 per share, or 38.01%, to close at $5.35 per share on July 28, 2026.
