- Brief Summary
This is a randomized, open-label, multi-center, global, Phase III study to determine the efficacy and safety of durvalumab + tremelimumab combination therapy versus platinum-based SoC chemotherapy in the first-line treatment of patients with epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) wild-type advanced or metastatic NSCLC.

- Primary Outcome Measures
Name Time Method Overall Survival (OS); Global Cohort: Blood Tumor Mutational Burden (bTMB) ≥20 Mutations Per Megabase (Mut/Mb) Analysis Set From baseline (Day 1, Week 0) until death due to any cause, assessed up to the Global cohort DCO date (a maximum of approximately 44 months). The OS was defined as the time from the date of randomization until death due to any cause (ie, date of death or censoring - date of randomization + 1). Any participant not known to have died at the time of analysis was censored based on the last recorded date on which the participant was known to be alive. Median OS was calculated using the Kaplan-Meier technique.
OS; China Cohort: China Programmed Cell Death Ligand 1 (PD-L1) Negative NSCLC Analysis Set From baseline (Day 1, Week 0) until death due to any cause, assessed up to the China cohort DCO date (a maximum of approximately 44 months). The OS was defined as the time from the date of randomization until death due to any cause (ie, date of death or censoring - date of randomization + 1). Any participant not known to have died at the time of analysis was censored based on the last recorded date on which the participant was known to be alive.
