A Study of Calderasib (MK-1084) in KRAS Mutant Advanced Solid Tumors (MK-1084-001)

Summary

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.
