KEYMAKER-U04 Substudy 04D: A Clinical Study of New Treatments Given With Enfortumab Vedotin and Pembrolizumab in People With Urothelial Cancer (MK-3475-04D/KEYMAKER-U04)
Sponsor: Merck Sharp & Dohme LLC
ClinicalTrials ID:NCT07232602
This substudy evaluates the safety and efficacy of MK-3120 with enfortumab vedotin and pembrolizumab in treating locally advanced or metastatic urothelial carcinoma. Eligible participants must have documented UC, provide a tumor sample, and meet specific health criteria. Interventions include IV infusions of MK-3120, EV, and pembrolizumab, with optional rescue medication.

Program Overview
Researchers are looking for new ways to treat people with urothelial cancer (UC) that is locally advanced or metastatic. The standard treatment for locally advanced or metastatic UC is enfortumab vedotin (EV) given with pembrolizumab.
The goals of this study are to learn about:
- The safety of the study treatment when given with standard treatment and if people tolerate it
- The number of people who have the cancer respond (cancer gets smaller or goes away) with the new study treatment when given with standard treatment.
Description
This is a substudy of the master protocol MK-3475-U04 (KEYMAKER-U04)
