Daraxonrasib (also called RMC-6236) is a direct “RAS(ON)” multi-selective inhibitor designed to target active, GTP-bound RAS, including a broad set of KRAS variants (not just KRAS G12C). The most recent public updates I can see focus on its clinical development in RAS-mutant pancreatic ductal adenocarcinoma (PDAC).[6][7][8][9]
Latest news highlights (DARAXONRASIB / RMC-6236)
- May 2026 (Phase 1/2 results in PDAC): Reporting indicates daraxonrasib showed initial anti-tumor activity in RAS-mutant pancreatic cancer, with the work attributed to teams including MD Anderson Cancer Center.[8][9][6]
- April 2026 (broader framing of pancreatic-cancer impact): Coverage describes daraxonrasib as potentially meaningful beyond earlier KRAS-targeted approaches that were limited to smaller KRAS subsets, attributing the rationale to its ability to address a broader range of RAS/KRAS variants.[2]
- June 2025 (regulatory milestone): The FDA granted Breakthrough Therapy Designation for daraxonrasib in previously treated metastatic PDAC with KRAS G12X mutations (as described in reporting).[7]
What protein target it’s hitting (the “KRAS protein target” part)
- Target state: It’s characterized as inhibiting RAS in its “on” state (active, GTP-bound RAS).[6]
- Target breadth: It’s described as aiming to inhibit multiple RAS variants (including KRAS G12X, G13X, and Q61X in at least some regulatory/clinical context).[7]
If you tell me whether you mean (a) KRAS mutations specifically in pancreatic cancer or (b) another indication (e.g., lung/colorectal/endometrial or something else), I can tailor the “latest news” roundup to that exact context.
