The FDA has granted enfortumab vedotin a breakthrough therapy designation for patients with locally advanced or metastatic urothelial cancer who previously received immune checkpoint therapy, according to Seattle Genetics and Astellas, the manufacturers of the antibody-drug conjugate (ADC).
The ongoing, pivotal phase II EV-201 trial (NCT03219333) is exploring enfortumab vedotin in this setting, and the phase I EV-103 trial (NCT03288545) is exploring the ADC in combination with either pembrolizumab (Keytruda) or atezolizumab (Tecentriq).
