Open-label Study of BBO-8520 in Adult Subjects With KRASG12C Non-small Cell Lung Cancer

Sponsored by TheRas, Inc., d/b/a BBOT (BridgeBio Oncology Therapeutics)

About this study

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 and BBO-10203 in subjects with locally advanced and unresectable or metastatic non-small cell lung cancer with a KRAS (Kirsten rat sarcoma) G12C mutation.

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 and BBO-10203 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
