Clinical Trial Summary

A first in human study to evaluate the safety, tolerability, and pharmacokinetics (PK) of BBO-8520, a KRAS G12C (ON) inhibitor, single agent and in combination with pembrolizumab in patients with advanced non-small cell lung cancer

Description:

This is an open-label, multi-center Phase 1a/1b study designed to evaluate the safety, tolerability, preliminary antitumor activity, and PK of BBO-8520 as a single agent and in combination with pembrolizumab in patients with KRAS (Kirsten rat sarcoma) G12C mutant non-small cell lung cancer. The study includes dose escalation phase, and expansion phase
