Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1
ORR was defined as the percentage of participants with observed tumor response of complete response (CR), or partial response (PR) determined according to RECIST version 1.1. CR was defined as the disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to \<10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The percentages of participants are rounded off to the nearest single decimal point.
Baseline up to disease progression or study treatment discontinuation (up to 38 months)
Secondary Outcomes (9)
Percentage of Participants With Disease Control Rate (DCR) Determined According to RECIST Version 1.1
Baseline up to disease progression or study treatment discontinuation (up to 38 months)
Duration of Response (DoR) According to RECIST Version 1.1
From first occurrence of documented CR or PR up to disease progression or study treatment discontinuation (assessed every 8 weeks after study treatment start for the first year, and every 12 weeks thereafter, up to 38 months)
Progression-Free Survival (PFS) According to RECIST Version 1.1
Study treatment initiation up to disease progression or study treatment discontinuation (up to 38 months)
Overall Survival (OS)
From first dose of study treatment up to death due to any cause (up to approximately 47 months)
Percentage of Participants With Adverse Events (AEs)
Baseline up to end of the study (up to approximately 47 months)
