A Study of Atezolizumab and Tiragolumab Compared With Durvalumab in Participants With Locally Advanced, Unresectable Stage III Non-Small Cell Lung Cancer (NSCLC)

Official Title

A Phase III, Open-Label, Randomized Study of Atezolizumab and Tiragolumab Compared With Durvalumab in Patients With Locally Advanced, Unresectable Stage III Non-Small Cell Lung Cancer Who Have Not Progressed After Concurrent Platinum-Based Chemoradiation

Summary:

The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.
