New drug combo shows promise in advanced lung cancer trial
NCT ID NCT04294810
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a new drug called tiragolumab to the standard immunotherapy atezolizumab works better than atezolizumab alone for people with advanced non-small cell lung cancer that has not been treated before. About 620 participants with high levels of a protein called PD-L1 on their tumors were randomly assigned to receive either the combination or a placebo plus atezolizumab. The goal was to see if the combination could delay cancer growth and improve survival.
