Daraxonrasib (also known as RMC-6236), a targeted RAS(ON) pathway inhibitor, has continued to generate the most recent “KRAS target” headlines based on new clinical activity updates—especially in RAS-mutant pancreatic ductal adenocarcinoma (PDAC).[6][8]
Latest reported updates (KRAS/RAS target context)
- May 2026 — Phase 1/2 activity update in RAS-mutant pancreatic cancer: Coverage reports that daraxonrasib showed promise in early trial data led by MD Anderson Cancer Center, with commentary focused on potential outcome improvements versus standard approaches in RAS-mutant disease.[8][6]
- 2025 — FDA Breakthrough Therapy Designation (regulatory milestone): Daraxonrasib received Breakthrough Therapy Designation for previously treated metastatic PDAC with KRAS G12 mutations (KRAS G12X), a milestone that typically signals substantial promise on clinically meaningful endpoints.[2][7]
Why these are being framed as “KRAS target” news
Daraxonrasib is discussed as targeting KRAS by inhibiting RAS signaling in its “on” state, and recent reporting emphasizes its broader coverage across RAS/variant forms relevant to pancreatic cancer biology—not just a single KRAS mutation.[6]
If you tell me whether you mean (1) pancreatic cancer only or (2) all cancers with KRAS, I can narrow the “latest news” to the most relevant sub-trials and mutation classes.
