Current Primary Outcome Measures (submitted: October 6, 2023)

• Progression-free Survival (PFS) [ Time Frame: Up to ~25 months ]
  PFS was defined as the time from randomization to the first documented progressive disease (PD) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR), or death due to any cause, whichever occurs 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 must also have demonstrated an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD. PFS as assessed by BICR per RECIST 1.1 is presented. Protocol-specified final analysis for this primary outcome measure was performed with an analysis data cut-off date of July-26-2021.
• Overall Survival (OS) [ Time Frame: Up to ~25 months ]
  OS was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were to be censored at the date of the last follow-up. Protocol-specified final analysis for this primary outcome measure was performed with an analysis data cut-off date of July-26-2021.

Original Primary Outcome Measures (submitted: March 29, 2019)

• Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR) [ Time Frame: Up to approximately 40 months ]
  PFS is defined as the time from randomization to the first documented progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥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 ≥5 mm. Note: The appearance of ≥1 new lesions is also considered PD.
• Overall Survival (OS) [ Time Frame: Up to approximately 40 months ]
  OS is defined as the time from randomization to the date of death from any cause.

Current Secondary Outcome Measures (submitted: October 6, 2023)

• Objective Response Rate (ORR) [ Time Frame: Up to ~25 months ]
  ORR was defined as the percentage of participants who had a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by BICR. The percentage of participants who experienced a CR or PR is presented. Protocol-specified final analysis for this secondary outcome measure was performed with an analysis data cut-off date of July-26-2021.
• Duration of Response (DOR) [ Time Frame: Up to ~25 months ]
  For participants who demonstrated a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by BICR, DOR was defined as the time from first documented evidence of a CR or PR until progressive disease (PD) or death. DOR for participants who had not progressed or died at the time of analysis was to be censored at the date of their last tumor assessment. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions as well as an absolute increase of ≥5 mm in the sum of diameters. The appearance of one or more new lesions was also considered PD. The DOR as assessed by BICR per RECIST 1.1 for participants who experienced a confirmed CR or PR is presented. Protocol-specified final analysis for this secondary outcome measure was performed with an analysis data cut-off date of July-26-2021.
• Disease Control Rate (DCR) [ Time Frame: Up to ~25 months ]
  DCR was defined at the percentage of participants who have a complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions) or stable disease (SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease [PD: ≥20% increase in the sum of diameters of target lesions and an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD]. DCR for participants who had not progressed or died at the time of analysis was to be censored at the date of their last tumor assessment. The DCR as assessed by BICR per RECIST 1.1 is presented. Protocol-specified final analysis for this secondary outcome measure was performed with an analysis data cut-off date of July-26-2021.

  The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions regarding Global Health Status (GHS; "How would you rate your overall health during the past week?") and Quality of Life (QoL; "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in GHS (EORTC QLQ-C30 Item 29) and QoL (EORTC QLQ-C30 Item 30) combined score will be presented. A higher score indicates a better outcome.

Descriptive Information

• Brief Title: Study of First-line Pembrolizumab (MK-3475) With Lenvatinib (MK-7902/E7080) in Urothelial Carcinoma Cisplatin-ineligible Participants Whose Tumors Express Programmed Cell Death-Ligand 1 and in Participants Ineligible for Platinum-containing Chemotherapy (MK-7902-011/E7080-G000-317/ LEAP-011)
• Official Title: 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)

Brief Summary

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).

With Amendment 3 (effective: September [Sep]-24-2021) participants discontinued lenvatinib and placebo; participants who remained on treatment in the study arms received open-label pembrolizumab.

With Amendment 3 the external Data Monitoring Committee was discontinued.

With Amendment 4 (effective: December-5-2022) Second Course will no longer be offered. Any participant receiving Second Course treatment prior to initiation of Amendment 4 will be able to complete treatment as planned.

With Amendment 4 study participation will end after the final administration of pembrolizumab. Participants who either complete 35 administrations of pembrolizumab or discontinue pembrolizumab will discontinue from the study following the safety follow-up visit. AEs and spontaneously reported pregnancies will be reported and followed per protocol. All participants in efficacy follow-up prior to initiation of Amendment 4 will stop efficacy assessments and be discontinued from the study. All participants in survival follow-up prior to initiation of Amendment 4 are considered to have completed the study and should have a final survival contact. The overall study ends when the last participant completes the last study-related contact or visit, withdraws from the study, or is lost to follow-up.
