Summary

This phase 3 trial tested whether combining two immunotherapy drugs, atezolizumab and tiragolumab, works better than the standard drug durvalumab for people with stage III lung cancer that cannot be surgically removed. The 829 participants had already received chemotherapy and radiation without their cancer growing. The goal was to see if the combo could delay cancer progression or improve survival.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Atezolizumab and tiragolumab (immunotherapy drugs)
What this could lead to
If this combination works better than durvalumab, it could offer a new standard treatment to keep stage III lung cancer from growing after chemoradiation.
What could go wrong
This is a large phase 3 trial, but the combination may not improve outcomes over the current drug durvalumab. Immunotherapy can cause immune-related side effects like inflammation of the lungs or other organs.
