A Study of GFH925 in Combination With Cetuximab in Previously Untreated Advanced NSCLC Harboring KRAS G12C Mutation

This is a Phase Ib/II study. The objectives are to evaluate the safety/tolerability and efficacy of GFH925 in combination with Cetuximab in advanced KRAS G12C mutant NSCLC, to characterize pharmacokinetics (PK) of GFH925 in combination with Cetuximab in advanced KRAS G12C mutant NSCLC
