I've been collecting the best articles, interviews, and papers on the success of daraxonrasib, and figured they might be useful to others too. So here they are, in one place.

On August 26, 2026, the FDA approved Revolution Medicines' Rasonque (daraxonrasib) for adults with metastatic pancreatic adenocarcinoma who have received at least one prior systemic therapy or are not candidates for multiagent systemic therapy.

The approval followed the RASolute 302 trial, in which median overall survival was 13.2 months with daraxonrasib and 6.7 months with chemotherapy. The hazard ratio for death was 0.40. For a disease that had resisted targeted therapy for decades, the result is a major clinical and scientific milestone.

RASolute 302: daraxonrasib vs chemotherapy

Median months in previously treated metastatic pancreatic cancer. Hazard ratio for death 0.40.

Overall survival

Daraxonrasib
13.2 mo
Chemotherapy
6.7 mo

Progression-free survival

Daraxonrasib
7.2 mo
Chemotherapy
3.6 mo

The story is also unusually rich. It encompasses the long effort to drug RAS, the development of a molecular glue that recruits cyclophilin A, the transformation of Revolution Medicines into a commercial company, and the emerging question of how cancers will escape RAS(ON) inhibition.

This page follows that story through the most useful reporting, interviews, commentaries, and scientific papers, grouped from discovery to what comes next. Each link is tagged by whether it's free to read or needs a subscription: Free, Open access, Subscription, or Research paper.
