Latest developments on daraxonrasib (RMC-6236)—an investigational pan-RAS inhibitor targeting RAS/RAF and related downstream signaling—include continued clinical reporting in RAS-mutant pancreatic cancer and additional preclinical work expanding where the mechanism may matter.
What’s new (recent)
- Pancreatic cancer clinical updates / 2026 coverage: Recent reporting highlights daraxonrasib’s activity and rationale in RAS-mutated pancreatic ductal adenocarcinoma (PDAC), including discussion of why newer “pan-RAS(ON)” strategies may overcome limitations seen with earlier KRAS-only drugs.[2]
- Phase 1/2 trial early activity mention (May 2026): An announcement describes daraxonrasib showing initial anti-tumor activity in RAS-mutant pancreatic cancer, based on results led by researchers at MD Anderson (phase 1/2).[10]
- Ongoing clinical significance of KRAS(variants) targeting: Daraxonrasib has been characterized as designed to inhibit “major forms” of oncogenic RAS(ON), with clinical readouts discussed in the context of ctDNA (RAS variant allele frequency reductions) and response/safety.[3]
Protein target / mechanism focus
- Daraxonrasib is positioned as a KRAS/pan-RAS pathway inhibitor that works by disrupting oncogenic RAS signaling and downstream pathways (e.g., RAF/MEK/ERK and PI3K/AKT), with downstream pathway suppression reported in KRAS-mutant settings.[1]
Where to look next (practical)
If you want, tell me whether you care more about (a) KRAS G12X pancreatic cancer trials, (b) broader “pan-RAS(ON)” preclinical findings, or (c) any specific sponsor/indication, and I’ll narrow to the most relevant recent headlines and primary sources.

The recently developed pan-KRAS inhibitor daraxonrasib, also known as RMC-6236, is capable of targeting a wide array of KRAS mutations and shows promise against pancreatic and lung cancers. However, the efficacy and mechanisms of action of daraxonrasib in osteosarcoma (OS) remain unclear. We evaluated the effects of daraxonrasib on the viability,...
