A Phase 1, Open-label, Multicenter Study to Assess Safety, Tolerability, PK, and Efficacy of MK-1084 as Monotherapy and as Part of Various Combination Therapies in Participants With KRAS G12C Mutant Advanced Solid Tumors
This is a study evaluating the safety, pharmacokinetics, and efficacy of calderasib alone, and calderasib plus other combination therapies in participants with advanced solid tumors with identified kirsten rat sarcoma viral oncogene homolog G12C (KRAS G12C) mutation.
