Secondary Outcome Measures

Name	Time	Method
Number of Participants With Clinically Significant TEAEs Related to Laboratory Abnormalities	Cycle 1 Day 1 up to 30 days after last dose of study drug (Arm 1 and 5: Cycle 19 Day 45; Arm 2: Cycle 7 Day 45; Arm 3: Cycle 22 Day 45; Arm 4: Cycle 25 Day 45
Number of Participants With Clinically Significant Vital Sign Abnormalities	Cycle 1 Day 1 up to 30 days after last dose of study drug (Arm 1 and 5: Cycle 19 Day 45; Arm 2: Cycle 7 Day 45; Arm 3: Cycle 22 Day 45; Arm 4: Cycle 25 Day 45
Percentage of Participants With Best Overall Response	Baseline up to end of treatment (approximately 1.9 years)	Best overall response for a participant is best observed post-baseline disease response as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1: Complete response (CR) was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis less than (\<) 10 millimeter \[mm\]). No new lesions. Partial response (PR) was defined as greater than or equal to (\>=) 30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Stable disease (SD) was defined as not qualifying for CR, PR, Progressive Disease (PD). An increase of \>=20% from the nadir (or baseline, if it represents the point at which the sum of target disease was lowest) represents PD.
Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)	Cycle 1 Day 1 up to 30 days after last dose of study drug (Arm 1 and 5: Cycle 19 Day 45; Arm 2: Cycle 7 Day 45; Arm 3: Cycle 22 Day 45; Arm 4: Cycle 25 Day 45)
