-
Replimune Group (REPL) faced a Complete Response Letter from the FDA in April 2026 regarding RP1 plus nivolumab for advanced melanoma, prompting the company to reassess its path forward and consider alternatives such as accelerated approval pathways or strategy adjustments. This development significantly influenced near-term prospects and manufacturing plans. [source: Stocktitan summary of 2026-04-26 reporting on the CRL and related context][1]
-
In 2025 and early 2026, Replimune presented updated IGNYTE trial data and biomarker analyses at SITC 2025, highlighting that RP1 may help overcome resistance mechanisms to PD-1 blockade and modulate gene signatures associated with PD-1 responsiveness. This suggests potential activity in PD-1–refractory settings, though regulatory approval remained unresolved.[1]
-
The company has continued communications with the FDA, including a Type A meeting in September 2025 to discuss the CRL and determine a path forward, with emphasis on extraordinary unmet need in advanced melanoma and consideration of accelerated approval pathways, though a definitive regulatory path had not been confirmed.[1]
-
FDA-related disclosures from 2024 note topline results from the IGNYTE trial showing a subset of patients responding to RP1 plus nivolumab, with durability of responses lasting beyond six months in the central review, informing ongoing discussions about efficacy evidence.[2]
-
Other coverage summarized various market and media reactions to the FDA feedback, including stock movement alongside the regulatory uncertainty, and notes about RP2 and RP3 development as potential follow-ons to broaden application beyond melanoma.[3]
