Primary Outcome Measures
NameTimeMethod
Disease-free Survival (DFS) in the PD-L1 ≥1% Population, Assessed by Investigator.Up to approximately 84 months

DFS was defined as the time from randomization to first recurrence of NSCLC, appearance of new primary NSCLC, or death from any cause, whichever occurred first. Tumor recurrence includes local recurrence and distant metastasis.

Disease-free Survival (DFS) in the ITT Population, Assessed by Investigator.Up to approximately 84 months
Secondary Outcome Measures
NameTimeMethod
DFS Within Selected PopulationsUp to approximately 108 months

Assessed by Investigator

Overall Survival (OS)Up to approximately 108 months

OS is defined as the time from random to death from any cause. OS will be measured in the PD-L1 subpopulation and in the ITT population.
