Brief Summary:
This is a study that will test how an experimental drug (enfortumab vedotin) affects patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra that has spread to nearby tissues or to other areas of the body.
This clinical trial will enroll patients who were previously treated with a kind of anticancer drug called an immune checkpoint inhibitor (CPI). Some CPIs have been approved for the treatment of urothelial cancer.
This study will test if the cancer shrinks with treatment. This study will also look at the side effects of the drug. A side effect is a response to a drug that is not part of the treatment effect.
Patients who sign up for this trial must also fall into one of these categories:
- Patients have already received treatment with platinum-containing chemotherapy
- Patients have never received platinum-containing treatment and are not eligible for treatment with cisplatin.

This study will examine the safety and anticancer activity of enfortumab vedotin given intravenously to patients with locally advanced or metastatic urothelial cancer who previously received a CPI and either previously received platinum-containing chemotherapy (Cohort 1) or are platinum-naïve and cisplatin-ineligible (Cohort 2). Patients who received platinum in the adjuvant/neoadjuvant setting and did not progress within 12 months of completion will be considered platinum-naïve. Approximately 100 patients are expected to be enrolled in each cohort. The primary goal of the study is to determine the confirmed ORR of enfortumab vedotin.

Primary Outcome Measures :
- Objective response rate (ORR) by an independent review facility (IRF) [ Time Frame: Up to 3 years ]The proportion of patients with confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1)
Secondary Outcome Measures :
- Duration of response (DOR) by an IRF [ Time Frame: Up to 7.5 years ]The time from first documentation of objective response (CR or PR that is subsequently confirmed) to the first documentation of progressive disease (PD) or to death due to any cause, whichever comes first
- Disease control rate at 16 weeks (DCR16) by an IRF [ Time Frame: 16 weeks ]Proportion of patients with CR, PR, or stable disease (SD) at Week 16 visit
- Progression free survival (PFS) by an IRF [ Time Frame: Up to 7.5 years ]The time from start of study treatment to first documentation of objective tumor progression (PD per RECIST 1.1), or to death due to any cause, whichever comes first
- ORR by investigator assessment [ Time Frame: Up to 7.5 years ]Confirmed CR and PR per RECIST 1.1
- DOR by investigator assessment [ Time Frame: Up to 7.5 years ]The time from first documentation of objective response (CR or PR that is subsequently confirmed) to the first documentation of PD or to death due to any cause, whichever comes first
- DCR16 by investigator assessment [ Time Frame: 16 weeks ]Proportion of patients with CR, PR, or SD at Week 16 visit
- Progression free survival (PFS) by investigator assessment [ Time Frame: Up to 7.5 years ]The time from start of study treatment to first documentation of objective tumor progression (PD per RECIST 1.1), or to death due to any cause, whichever comes first
- Overall survival (OS) [ Time Frame: Up to 7.5 years ]The time from start of study treatment to date of death due to any cause
- Incidence of adverse events (AEs) [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Descriptive statistics will be used to summarize results
- Incidence of laboratory abnormalities [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Descriptive statistics will be used to summarize results
- Pharmacokinetics (PK) parameter for enfortumab vedotin: Maximum concentration (Cmax) [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Cmax will be derived from the PK blood samples collected
- PK parameter for enfortumab vedotin: Trough concentration (Ctrough) [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Ctrough will be derived from the PK blood samples collected
- PK parameter for monomethyl auristatin E (MMAE): Cmax [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Cmax will be derived from the PK blood samples collected
- PK parameter for MMAE: Ctrough [ Time Frame: Through 1 month following last dose, or end-of-treatment visit whichever is later, up to 7.5 years ]Ctrough will be derived from the PK blood samples collected
