A Study Evaluating FMC-376 in Participants With KRAS G12C Mutated Solid Tumors

The goal of this clinical trial is to evaluate FMC-376 in participants with advanced solid tumors with KRAS G12C mutations. This clinical trial will be conducted in 3 parts: Phase 1A (Dose Escalation), Phase 1B (Dose Expansion), and Phase 2 (Cohort Expansion). Multiple dose levels in participants with advanced solid tumors will be evaluated.

Inclusion Criteria: * Histologically or cytologically confirmed locally advanced unresectable or metastatic solid tumors with KRAS G12C mutation * Received and progressed or been intolerant to prior standard therapy OR standard therapy is considered inappropriate OR an investigational agent is considered standard of care * Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 * Adequate hematological, renal, and hepatic function * Agrees not to participate in another interventional study while receiving study drug Exclusion Criteria: * Leptomeningeal disease or carcinomatous meningitis * Clinically significant toxicity resulting from prior cancer therapies * Known or suspected hypersensitivity to FMC-376 or any components of the study drug * Condition that would interfere with study drug absorption * Any illness or medical history that would impact safety or compliance with study requirements or impact ability to interpret study data
