The main objective of the study is to measure the clinical activity and safety of zelenectide pevedotin formally BT8009, in combination with pembrolizumab versus chemotherapy, and as monotherapy in participants with locally advanced or metastatic urothelial cancer (UC). The study includes a dose selection for zelenectide pevedotin and is comprised of 2 cohorts. Cohort 1 will include participants who have not received any prior systemic therapy for locally advanced or metastatic UC and are eligible to receive platinum-based chemotherapy, whereas Cohort 2 will include participants who have received ≥ 1 prior systemic therapy for locally advanced or metastatic UC.
