PADCEV + KEYTRUDA improve Survival in Bladder Cancer

Pfizer Inc. and Astellas Pharma Inc. announced positive topline results from the Phase 3 EV-303 clinical trial (also known as KEYNOTE-905). The EV-303 study is evaluating PADCEV™ (enfortumab vedotin), a Nectin-4 directed antibody-drug conjugate, in combination with KEYTRUDA™ (pembrolizumab), a PD-1 inhibitor, as neoadjuvant and adjuvant treatment (before and after surgery) versus surgery alone, the current standard of care, in patients with muscle-invasive bladder cancer (MIBC) who are not eligible for or declined cisplatin-based chemotherapy. At the first interim efficacy analysis, the trial demonstrated a clinically meaningful and statistically significant improvement in event-free survival (EFS), the study’s primary endpoint, and overall survival (OS), a key secondary endpoint, with neoadjuvant and adjuvant PADCEV plus KEYTRUDA versus surgery alone. An additional secondary endpoint of pathologic complete response (pCR) rate was also met.…
