What was measured
DC is defined as overall CR, PR, or stable disease (SD) \>=24 weeks according to RECIST version 1.1. Disease Control Rate (DCR) is defined as participants with CR, PR, or SD \>=24 weeks relative to all randomized participants. Participants who do not have on-study radiographic tumor reevaluation, who received anti-tumor treatment, a best response of SD\>=24 weeks, or who died, progressed, or dropped out for any reason prior to achieving reaching a CR or PR and a best response of SD\>=24 weeks was counted as non-responders in DCR. Per RECIST v1.1, CR: Complete disappearance of target lesions with exception of nodal disease. All target nodes must decrease to normal size (short axis \<10mm). PR: \>=30% decrease under baseline of the sum of diameters of all target measurable lesions. The short diameter is used in the sum for target nodes, while the longest diameter is used in the sum for all other target lesions. SD: neither sufficient shrinkage nor increase to qualify for disease progression.
Analysis population: ITT population or full analysis set included all participants who were randomized, with study medication, regardless of whether participants received study medication or received a different drug from that to which they were randomized.
