- Metastatic disease or locally advanced disease that is not resectable.
- Must have received prior treatment with a CPI in the locally advanced or metastatic urothelial cancer setting. A CPI is defined as a programmed cell death protein 1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor. Patients who received CPI therapy in the neoadjuvant/adjuvant setting and had recurrent or progressive disease either during therapy or within 3 months of therapy completion are eligible.
- Must either have prior treatment with platinum-containing chemotherapy (Cohort 1) or be platinum-naïve and ineligible for treatment with cisplatin at time of enrollment (Cohort 2).
- Must have had progression or recurrence of urothelial cancer during or following receipt of most recent therapy.
- Tumor tissue samples must be available for submission to the sponsor prior to study treatment.
- Must have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1).
- An Eastern Cooperative Oncology Group (ECOG) Performance Status score of ≤1 for Cohort 1 or ≤2 for Cohort 2.
- Anticipated life expectancy of ≥3 months as assessed by the investigator.
- Ongoing sensory or motor neuropathy Grade ≥2.
- Active central nervous system (CNS) metastases.
- Immunotherapy related myocarditis, colitis, uveitis, or pneumonitis.
- Prior enrollment in an enfortumab vedotin study or prior treatment with other monomethyl auristatin E (MMAE)-based antibody-drug conjugates (ADCs).
