The purpose of this study is to find out whether the study drug, LY3537982, is safe and effective in cancer patients who have a specific genetic mutation (KRAS G12C). Patients must have already received or were not able to tolerate the standard of care. The study will last up to approximately 2 years.


This is an open-label, multicenter Phase 1 study to evaluate safety, tolerability, and preliminary efficacy of oral LY3537982 in patients with KRAS G12C-mutant solid tumors.

This study will be conducted in 2 parts, Part 1a is a dose escalation and Part 1b is a dose expansion. Part 1a will establish a recommended Phase 2 dose. Part 1b will have multiple arms of either monotherapy or in combination with other drugs.

KRAS G12C mutations will be identified through standard of care testing.
