AI Summary
Replimune disclosed 3-year overall survival data from the IGNYTE trial of RP1 plus nivolumab in anti-PD-1–failed melanoma, showing a median OS of 32.9 months and 47.8% alive at 3 years, with 83.5% of responders still living. ORR was 33.6% with 24.8 months median duration of response, and 44.8% of responders maintained response at 3 years, all with a favorable safety profile. These results could support upcoming regulatory timing for RP1 and bolster investor confidence in the RPx platform.
Sentiment Rationale
Durable survival signals and strong safety reduce downside risk and may boost valuation expectations if paired with FDA timing catalysts.
