Lung cancer combo trial halted early: what happened?
NCT ID NCT06267001
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding tiragolumab to atezolizumab could help prevent lung cancer from returning after surgery and chemotherapy. It included 56 adults with a specific type of lung cancer (PD-L1 positive, stages IIB to IIIB). The trial was terminated early, so results are limited. The main goal was to check safety and side effects.
