Brief Summary

This study will assess the safety and efficacy of avutometinib (VS-6766) in combination with sotorasib with or without defactinib in patients with KRAS G12C Non-Small Cell Lung Cancer (NSCLC) in patients who have been exposed to prior G12C inhibitor and those who have not been exposed to prior G12C inhibitor.

Detailed Description

This is a multicenter, non-randomized, open-label Phase 1/2 study designed to evaluate safety and tolerability and efficacy of avutometinib (VS-6766) in combination with sotorasib with or without defactinib in patients with KRAS G12C mutant NSCLC.
