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%).

| Primary | Pembro Combo vs Chemo: Progression-free Survival (PFS) Using Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR) | 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. |

| Secondary | Number of Participants Who Experience an Adverse Event (AE) | An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants that experienced at least one AE was reported for each treatment arm. | Up to approximately 55 months | |

Using linear transformation, raw scores were standardized so that scores ranged from 0 to 100, with a higher score indicating a better overall outcome. Per protocol, change from baseline to Week 18 in the GHS/QoL combined score was compared between all participants of the pembro combo arm and the chemo arm as a pre-specified secondary analysis.
