Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with histologically confirmed locally advanced or metastatic non-small cell lung cancer with a KRAS G12C mutation and an ECOG performance status of 0-1.

Probably not a fit

Patients with untreated brain metastases or those with a history of autoimmune diseases 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, multi-center Phase 1 study aims to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of BBO-8520, a direct inhibitor of KRAS G12C, both as a standalone treatment and in combination with pembrolizumab. The trial focuses on adult patients with locally advanced and unresectable or metastatic non-small cell lung cancer harboring the KRAS G12C mutation. It includes a dose escalation phase followed by a dose expansion phase to gather comprehensive data on the drug's performance.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with KRAS G12C mutated non-small cell lung cancer.

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