Pfizer Inc. (NYSE: PFE) and Astellas Pharma Inc. (TYO: 4503) announced that the U.S. Food and Drug Administration (FDA) approved PADCEV (enfortumab vedotin) in combination with Keytruda (pembrolizumab) for perioperative treatment of adult patients with muscle‑invasive bladder cancer (MIBC) who are ineligible for cisplatin‑containing chemotherapy, based on the EV‑303/KEYNOTE‑905 Phase 3 trial showing a 60% reduction in recurrence, progression, or death risk.
Global Approvals: Already approved for locally advanced/metastatic urothelial cancer (la/mUC) in the U.S., Japan, and other markets; EU approved for la/mUC in platinum‑eligible patients; PADCEV monotherapy approved for la/mUC post‑PD‑1/platinum
Innovation: First perioperative ADC‑IO regimen in bladder cancer, addressing pre‑ and post‑surgical treatment
