Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A first in human study to evaluate the safety and preliminary antitumor activity of BBO-8520, a KRAS G12C (ON and OFF) inhibitor, as a single agent and in combination with pembrolizumab in subjects with locally advanced and unresectable or metastatic non-small cell lung cancer with a KRAS (Kirsten rat sarcoma) G12C mutation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an open-label, multi-center, Phase 1 study designed to evaluate the safety, tolerability, pharmacokinetics, and efficacy of BBO-8520, a direct inhibitor of KRASG12C (ON and OFF), alone and in combination with the ICI pembrolizumab in subjects with locally advanced and unresectable or metastatic non-small cell lung cancer with a KRAS (Kirsten rat sarcoma) G12C mutation. The study includes dose escalation phase and dose expansion phase
