Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with KRAS G12C-mutated advanced or metastatic solid tumors that are not amenable to curative therapy.

Probably not a fit

Patients with primary central nervous system tumors or active brain metastases may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label, multicenter Phase 1b study aims to assess the safety, tolerability, and pharmacokinetics of RMC-6291 in combination with RMC-6236 in adults with advanced KRAS G12C-mutated solid tumors. The study is divided into two parts: a dose-escalation phase to determine the maximum tolerated dose and a dose-expansion phase to evaluate preliminary antitumor activity. Participants will include those with non-small cell lung cancer, colorectal cancer, and pancreatic ductal adenocarcinoma who have previously undergone treatment. The study seeks to provide insights into effective treatment options for this specific mutation.

Why it matters

Potential benefit: If successful, this study could offer a new therapeutic option for patients with advanced KRAS G12C-mutant solid tumors.

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