Primary Outcome Measures
NameTimeMethod
Overall Survival (OS) in All ParticipantsUp 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≥1Up 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
NameTimeMethod
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.
