Daraxonrasib (RMC-6236) is a next-generation, non-covalent RAS(ON) multi-selective inhibitor that targets active RAS-GTP complexes across multiple RAS mutations (G12D, G12V, G12C, Q61H). It demonstrates potent anti-tumor activity by inhibiting downstream MAPK signaling pathway activation.

EC50 values range from 0.1- 3.1 nM across various mutant RAS cell lines, showing superior selectivity and efficacy compared to covalent inhibitors. Clinical studies have demonstrated significant tumor regression in KRAS-mutant solid tumors with manageable safety profile.

In Vitro Activity

  • Mechanism: Binds to switch-II pocket of active RAS-GTP, preventing effector protein interaction
  • Cell Lines: Potent inhibition in KRAS G12D, G12V, G12C mutant pancreatic, colorectal, and NSCLC cell lines
  • pERK Inhibition: >90% reduction in phosphorylated pERK at 100 nM concentration

In Vivo Activity

  • Animal Models: Significant tumor growth inhibition in KRAS-mutant xenograft models (PDX and CDX)
  • Dosage Response: Dose-dependent efficacy observed at 10-50 mg/kg oral administration
  • Combination Therapy: Enhanced efficacy when combined with MEK inhibitors or immunotherapy agents
