- Overall Survival (OS) in Participants With Programmed Death-Ligand 1 (PD-L1) With a Combined Positive Score (CPS) ≥20 [ Time Frame: From randomization to date of death or date the participant was last known to be alive (Up to approximately 55 months) ]Overall survival (OS) is defined as the time between randomization and death. For participants without documentation of death, OS will be censored on the last date the participant was known to be alive. Overall survival will be censored at the date of randomization for participants who were randomized but had no follow-up. Survival follow-up will be conducted every 3 months after participants off-treatment date. (Based on Kaplan-Meier estimates)
- Overall Survival (OS) in All Randomized Participants [ Time Frame: From randomization to date of death or date the participant was last known to be alive (Up to approximately 55 months) ]Overall survival (OS) is defined as the time between randomization and death. For participants without documentation of death, OS will be censored on the last date the participant was known to be alive. Overall survival will be censored at the date of randomization for participants who were randomized but had no follow-up. Survival follow-up will be conducted every 3 months after participants off-treatment date. (Based on Kaplan-Meier estimates)
- Overall Survival (OS) in Randomized Participants With Programmed Death-Ligand 1 (PD-L1) With a Combined Positive Score (CPS) ≥ 1 [ Time Frame: From randomization to date of death or date the participant was last known to be alive (Up to approximately 55 months) ]Overall survival (OS) is defined as the time between randomization and death. For participants without documentation of death, OS will be censored on the last date the participant was known to be alive. Overall survival will be censored at the date of randomization for participants who were randomized but had no follow-up. Survival follow-up will be conducted every 3 months after participants off-treatment date. (Based on Kaplan-Meier estimates)
- Progression Free Survival (PFS) [ Time Frame: From randomization to disease progression or death (Up to approximately 55 months) ]
The time from randomization to disease progression, using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, or, if there is no documented progression, death based on the Blinded Independent Central Review (BICR) assessment. Participants who neither progress nor die will be censored on the date of their last tumor assessment. Participants who receive subsequent anti-cancer therapy prior to documented progression, will be censored on the date of their last tumor assessment prior to subsequent therapy. (Based on Kaplan-Meier Estimates)
Progression is defined as at least a 20% increase in the sum of diameters of target lesions, in addition the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).
- Objective Response Rate (ORR) [ Time Frame: From randomization up to approximately 55 months ]
Objective Response Rate (ORR) is defined as the number of participants with a best overall response (BOR) of complete response (CR) or partial response (PR), divided by the number randomized in the population. Based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria by blinded independent central review (BICR) assessment.
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
- Duration of Objective Response (DOR) [ Time Frame: From randomization up to approximately 55 months ]
The time between the first documented response (Complete response (CR) or partial response (PR)) and progression or death, per RECIST 1.1 by blinded independent central review (BICR) assessment. (Based on Kaplan-Meier Estimates)
Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.
Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
