- Primary Outcome Measures
Name Time Method Overall Survival (OS) in All Participants Up to approximately 36 months OS was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. OS is reported here for all participants in the experimental arm and placebo comparator arm.
Overall Survival (OS) in Participants With PD-L1 CPS≥1 Up to approximately 36 months OS was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. OS is reported here for all participants in the experimental arm and placebo comparator arm with PD-L1 CPS≥1.
- Secondary Outcome Measures
Name Time Method Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Up to approximately 36 months PFS was defined as the time from randomization to the first documented disease progression per RECIST 1.1 assessed by investigators or death due to any cause, whichever occurs first.
Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Up to approximately 36 months ORR was defined as the percentage of participants who have a complete response (CR) or a partial response (PR), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by investigators.
Disease Control Rate (DCR) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Up to approximately 36 months DCR was defined as the percentage of participants who have a CR or a PR or a stable disease (SD), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by investigators.
Duration of Response (DOR) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Up to approximately 36 months DOR was defined as the time from the first documented evidence of a response of CR or PR, per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by investigators.
