Participants with metastatic or locally advanced/unresectable urothelial cancer that has recurred or progressed following platinum-based chemotherapy will be randomly assigned to receive Investigator's choice of paclitaxel, docetaxel, or vinflunine (Control), or pembrolizumab. The primary study hypotheses are that pembrolizumab will prolong Overall Survival (OS) and Progression-free Survival (PFS) compared to paclitaxel, docetaxel, or vinflunine.

    PFS was defined as the time from randomization to the first documented disease progression, or death due to any cause, whichever occurred first. Per RECIST 1.1, progressive disease (PD) was defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Note: The appearance of one or more new lesions was also considered PD.

brief Summary
Participants with metastatic or locally advanced/unresectable urothelial cancer that has recurred or progressed following platinum-based chemotherapy will be randomly assigned to receive Investigator's choice of paclitaxel, docetaxel, or vinflunine (Control), or pembrolizumab. The primary study hypotheses are that pembrolizumab will prolong Overall Survival (OS) and Progression-free Survival (PFS) compared to paclitaxel, docetaxel, or vinflunine.
detailed Description
For the purposes of this study, participants with a programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥10% were considered to have a strongly PD-L1 positive tumor status and participants with PD-L1 CPS ≥1% were considered to have a PD-L1 positive tumor status. Effective with Amendment 15, eligible participants who are allocated to the Control arm (Investigator's Choice) and experience disease progression will be provided with the opportunity to switch over to receive pembrolizumab 200 mg one time every three weeks (Q3W) for up to two years of treatment.
