  Purpose

The purpose of this study is to determine the efficacy and safety of pembrolizumab (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 participants with programmed cell death ligand 1 (PD-L1) positive tumors (Combined Positive Score [CPS] ≥10%) and in all participants (includes those participants with PD-L1 positive tumors and those with PD-L1 negative tumors [CPS <10%]).

Criteria

Inclusion Criteria:

  • Has a histologically or cytologically confirmed diagnosis of advanced/unresectable (inoperable) or metastatic urothelial carcinoma of the renal pelvis, ureter [upper urinary tract], bladder, or urethra. Both transitional cell and mixed transitional/non- transitional cell histologies are allowed, but transitional cell carcinoma must be the predominant histology.
  • Has measurable disease based on RECIST 1.1 as determined by the local site investigator/radiology assessment.
  • Has received no prior systemic chemotherapy for advanced or metastatic urothelial carcinoma, with the following exceptions:

    • Neoadjuvant platinum-based chemotherapy with recurrence >12 months from completion of therapy is permitted.
    • Adjuvant platinum-based chemotherapy following radical cystectomy with recurrence >12 months from completion of therapy is permitted.
  • Has provided tissue for biomarker analysis from an archival tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated from a muscle invasive urothelial carcinoma or a metastatic biopsy, originally from the original tumor.
  • Has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2.
