Evaluating FMC-376 for advanced solid tumors with KRAS G12C mutations

An Open-Label, Phase 1/2 Dose Escalation, Dose Expansion and Cohort Expansion Study Evaluating the Safety, PK and Clinical Activity of FMC-376 in Participants With KRAS G12C Mutated Locally Advanced Unresectable or Metastatic Solid Tumors

Phase1; Phase2 Interventional Frontier Medicines Corporation · NCT06244771

This study is testing a new drug called FMC-376 to see if it can help people with advanced solid tumors that have a specific KRAS G12C mutation.

What this trial studies

This clinical trial aims to assess the safety and efficacy of FMC-376 in patients with advanced solid tumors harboring KRAS G12C mutations. The study is structured in three parts: Phase 1A focuses on dose escalation, Phase 1B on dose expansion, and Phase 2 on cohort expansion to further evaluate the drug's effects. Participants will be closely monitored for responses and side effects throughout the trial. The goal is to identify optimal dosing and therapeutic benefits of FMC-376 in this specific patient population.

Who should consider this trial

Good fit: Ideal candidates include adults with advanced solid tumors that have a confirmed KRAS G12C mutation and have either progressed on or are intolerant to prior therapies.

Not a fit: Patients with leptomeningeal disease, significant toxicity from previous treatments, or those with conditions affecting drug absorption may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new targeted therapy option for patients with KRAS G12C mutated solid tumors.

How similar studies have performed: Other studies targeting KRAS mutations have shown promise, indicating potential for success with this novel approach.
