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)
MK-3120: Administered via intravenous (IV) infusion on day 1 and day 8 of each 3-week cycle
EV: Administered via IV infusion on day 1 and day 8 of each 3-week cycle
Pembrolizumab: Administered via IV infusion on day 1 of each 3-week cycle
Rescue Medication: Participants receive rescue medication at the investigator's discretion, per approved product label. Recommended rescue medication is Granulocyte Colony-Stimulating Factor (G-CSF).
Study summary
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.

Primary outcome measure(s)
Number of Participants Who Experience an Adverse Event (AE) — Up to approximately 27 months An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that experience AEs will be reported.
Number of Participants Who Experience a Dose Limiting Toxicity (DLT) — Up to approximately 21 days DLT will be defined as any drug-related AE observed during the DLT evaluation period that results in a change to a given dose or a delay in initiating the next treatment. The number of participants who experience a DLT as Assessed Using Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 will be presented.
Number of Participants Who Discontinue Study Treatment Due to an AE — Up to approximately 24 months An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants that discontinue study intervention due to an AE will be reported.
Objective Response Rate (ORR) as Assessed by Investigator — Up to approximately 58 months ORR is defined as the percentage of participants with 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 Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Investigator will be presented.
