Enfortumab vedotin showed strong clinical activity in patients with locally advanced or metastatic urothelial carcinoma who previously received both platinum-containing chemotherapy and immune checkpoint therapy, according to topline results from the pivotal phase II EV-201 trial announced by Seattle Genetics and Astellas, the manufacturers of the antibody-drug conjugate (ADC).

Grade ≥3 AEs in the RP2D cohort included urinary tract infection (8%), hypophosphatemia (3%), hyponatremia (5%), anemia (8%), and hyperuricemia (5%). Across all treatment doses, there were 3 patient deaths (cardiac arrest, small intestinal perforation and sepsis, and acute renal failure), none of which was considered to be related to enfortumab vedotin.
