CheckMate 73L: A Phase 3 Study Comparing Nivolumab Plus Concurrent Chemoradiotherapy Followed by Nivolumab With or Without Ipilimumab Versus Concurrent Chemoradiotherapy Followed by Durvalumab for Previously Untreated, Locally Advanced Stage III Non-Small-Cell Lung Cancer.
Summary
The primary purpose of the study is to compare the effectiveness of nivolumab plus concurrent chemoradiotherapy (CCRT) followed by nivolumab plus ipilimumab vs CCRT followed by durvalumab in participants with untreated Locally Advanced Non-small Cell Lung Cancer (LA NSCLC).

Exclusion Criteria
- Any condition including medical, emotional, psychiatric, or logistical that, in the opinion of the Investigator would preclude the participant from adhering to the protocol or would increase the risk associated with study participation

- History of organ or tissue transplant that requires systemic use of immune suppressive agents
- Prior thoracic radiotherapy
Other protocol-defined inclusion/exclusion criteria apply
