A Phase 3, Randomized, Double-blind Study to Compare the Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Lenvatinib (E7080/MK-7902) Versus Pembrolizumab and Placebo as First Line Treatment for Locally Advanced or Metastatic Urothelial Carcinoma in Cisplatin-ineligible Participants Whose Tumors Express PD-L1, and in Participants Ineligible for Any Platinum-containing Chemotherapy Regardless of PD-L1 Expression (LEAP-011)

The purpose of this study is to evaluate the efficacy and safety of lenvatinib (MK-7902/E7080) in combination with pembrolizumab (MK-3475) in the treatment of cisplatin-ineligible participants with a Programmed Cell Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10, or in participants ineligible for any platinum-containing chemotherapy regardless of CPS, with advanced/unresectable or metastatic urothelial carcinoma (UC). The primary hypotheses for this study are that: 1. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR), and 2. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Overall Survival (OS).

         - Other reason for the participant's being unable to receive carboplatin safely. Additional criteria for platinum ineligibility will be considered and allowed on a case-by-case basis, following consultation with the Sponsor.

         - Agrees to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a woman of childbearing potential (WOCBP) who is not currently pregnant. Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration.

         - A female participant is eligible to participate if she is not pregnant or breastfeeding and if she is not a WOCBP OR is a WOCBP and is using a contraceptive method that is highly effective (with a failure rate of <1% per year) with low user dependency, or is abstinent from heterosexual intercourse as her preferred and usual lifestyle during the intervention period and for ≥120 days after the last dose of pembrolizumab or lenvatinib/placebo.
