The purpose of this study is to determine the efficacy and safety of pembrolizumab (pembro, MK-3475) with or without chemotherapy versus chemotherapy alone in participants with advanced or metastatic urothelial carcinoma (bladder cancer). The primary hypotheses are that pembrolizumab plus chemotherapy is superior to chemotherapy alone with respect to Progression-free Survival (PFS) and Overall Survival (OS) in all participants, and that pembrolizumab alone is superior to chemotherapy alone with respect to OS in all participants and in participants with programmed cell death ligand 1 (PD-L1) positive tumors (Combined Positive Score \[CPS\] ≥10%).

    PFS was defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on BICR, or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum had to demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD. The sponsor allowed a maximum of 10 target lesions in total and 5 per organ on this study. Per protocol, PFS in the pembro combo arm was compared to the chemo arm as a pre-specified primary analysis of the Intent-To-Treat (ITT) population (all randomized participants). PFS is reported here for all participants in the pembro combo arm and chemo arm. Per protocol, PFS was compared separately between all participants of the pembro arm and chemo arm and is presented later in the record.

Full study description
brief Summary
The purpose of this study is to determine the efficacy and safety of pembrolizumab (pembro, MK-3475) with or without chemotherapy versus chemotherapy alone in participants with advanced or metastatic urothelial carcinoma (bladder cancer). The primary hypotheses are that pembrolizumab plus chemotherapy is superior to chemotherapy alone with respect to Progression-free Survival (PFS) and Overall Survival (OS) in all participants, and that pembrolizumab alone is superior to chemotherapy alone with respect to OS in all participants and in participants with programmed cell death ligand 1 (PD-L1) positive tumors (Combined Positive Score \[CPS\] ≥10%).
detailed Description
As specified by the protocol, the study hypotheses will be evaluated by comparing the pembro combo arm or pembro arm separately to the chemo arm.
