- Progression-free survival (PFS) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR) [ Time Frame: Up to approximately 31 months ]Progression-free survival based on RECIST 1.1 as assessed by BICR. Progression-free survival is measured from the time of randomization to the first documented disease progression or death due to any cause, whichever occurs first.
- Overall Survival (OS) [ Time Frame: Up to approximately 45 months ]Overall survival is measured from the time of randomization up to death due to any cause.
- Objective response rate (ORR ) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by blinded independent review (BICR) [ Time Frame: Up to approximately 31 months ]The ORR (either confirmed complete response [CR] or partial response [PR]) based on RECIST 1.1 and assessed by BICR will be determined in mismatch repair proficient (pMMR) participants and in all-comer participants who have measurable disease at study entry.
- Change from baseline in the global score of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30) in pMMR and in all-comer participants [ Time Frame: Baseline and designated time points up to 27 months ]The EORTC QLQ-C30 was developed to assess the quality of life of patients with cancer. It contains 30 questions (items), 24 of which aggregate into nine multi-item scales representing various aspects, or dimensions, of quality of life (QoL): one global scale, five functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, nausea, pain), and six additional single-symptom items assessing additional symptoms commonly reported by cancer patients (dyspnoea, loss of appetite, insomnia, constipation and diarrhoea) and perceived financial impact of the disease. Individual items are scored on a 4-point scale (1=not at all, 2=a little, 3=quite a bit, 4=very much). Raw scores for each scale are standardized into a range of 0 to 100 by linear transformation; a higher score on the global and functional scales represents a higher ("better") level of functioning, and a higher score on the symptom scale represents a higher ("worse") level of symptoms.
- Percentage of participants experiencing an adverse event (AE) [ Time Frame: Up to approximately 27 months (through 90 days after the last dose of study treatment) ]An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
- Percentage of participants experiencing a serious adverse event (SAE) [ Time Frame: Up to approximately 28 months (through 120 days after the last dose of study treatment) ]An SAE is an AE that results in death, is life-threatening, requires or prolongs hospitalization, results in persistent or significant disability, is a congenital birth defect, or is another important medical event.
- Percentage of participants experiencing an immune-related AE (irAE) [ Time Frame: Up to approximately 27 months (through 90 days after the last dose of study treatment) ]Immune-related AEs will be monitored in both arms.
- Percentage of participants discontinuing from study treatment due to an AE(s) [ Time Frame: Up to approximately 24 months (through the last dose of study treatment) ]Discontinuations related to AEs will be monitored in both arms.
