Allele-Specific Mechanisms Guide Salvage Therapy to Overcome Daraxonrasib Resistance in Pancreatic Cancer.
Clinical-grade RAS inhibitors raise an unresolved question as to whether KRAS alleles impose constraints on adaptive resistance that can be exploited therapeutically. Using daraxonrasib (RMC-6236), a multi-selective RAS(ON) inhibitor, we compared resistance mechanisms between KRASG12D and KRASG12R, mutants with fundame...
