Padcev-Keytruda Combination Shows Strong Positive Data in Cisplatin-Eligible Muscle-Invasive Bladder Cancer
The Phase 3 KEYNOTE-B15/EV-304 trial demonstrated that KEYTRUDA (pembrolizumab) plus Padcev (enfortumab vedotin) reduced the risk of event-free survival (EFS) events by 47% and the risk of death by 35% compared to neoadjuvant chemotherapy in cisplatin-eligible patients with muscle-invasive bladder cancer (MIBC) when given before and after surgery. 1 2 Statistically significant improvements in overall survival and pathological complete response were observed, with over half of patients showing no detectable disease at surgery. 2 This builds on prior Phase 3 trials like KEYNOTE-905 and KEYNOTE-A39, showing OS benefits across bladder cancer stages, potentially establishing a new standard of care. 1 2 Announced by Merck, Pfizer, and Astellas; results to be discussed with health authorities for regulatory filings. 1 2 3 Sources: 1. https://www.merck.com/news/keytruda-pembrolizumab-plus-padcev-enfortumab-vedotin-ejfv-reduced-risk-of-event-free-survival-events-by-47-and-risk-of-deat...
