RASONQUE

Daraxonrasib is an inhibitor of the RAS GTPase family. Daraxonrasib binds to cyclophilin A, resulting in a binary complex that binds to the active, GTP-bound state of RAS. The tri-complex inhibits RAS signaling by blocking interactions with downstream effectors and promoting GTP hydrolysis to the inactive GDP-bound state of RAS. Daraxonrasib inhibition of wild-type and mutant variants of KRAS, NRAS, and HRAS induces tumor growth suppression and apoptosis. In RAS-dependent models of pancreatic adenocarcinoma, daraxonrasib treatment led to tumor growth inhibition and regression and is associated with antitumor immunity.
