Daraxonrasib Phase 1/2 data in 2L PDAC showed encouraging mOS (~14mo) vs historical 5-7mo SOC, supporting biological rationale. However, OS in pancreatic cancer Phase 3 is notoriously hard to hit; cross-over, subsequent therapies, and SOC chemo heterogeneity dilute effects. Dual primary (PFS/OS) helps, but market endpoint is OS specifically. Co-primary alpha-split and broad RAS G12 population add risk. Slight lean negative on OS readout at this completion date given typical maturity timelines.

Daraxonrasib (RMC-6236) showed compelling Phase 1/2 data in 2L PDAC with ~8mo PFS and ~14mo OS in RAS G12-mutant patients, far exceeding historical SOC (~3mo PFS, ~6mo OS). RAS G12 mutations cover ~90% of PDAC. Pan-RAS(ON) inhibition has strong mechanistic rationale. Risks: crossover, single-arm benchmark inflation, and OS being harder than PFS. Phase 3 RASolute 302 powered for OS; readout imminent.aud prior data supports positive OS signal.[truncated]
