New targeted pill aims to keep KRAS lung cancer from returning after surgery
NCT ID NCT07541170
First seen Jun 27, 2026 · Last updated Sep 10, 2026 · Updated 5 times
Summary
This study tests whether the drug divarasib can prevent lung cancer from coming back in people with a specific gene mutation (KRAS G12C) who have already had surgery and chemotherapy. About 400 adults with stage II-III non-small cell lung cancer will be randomly assigned to receive divarasib, standard immunotherapy, or just observation. The goal is to see which approach works best for keeping the cancer away.
