Pembrolizumab Plus Enfortumab Vedotin Earns EC Approval in Resectable MIBC

The European Commission approved pembrolizumab (Keytruda) plus enfortumab vedotin (Padcev) for resectable muscle-invasive bladder cancer (MIBC). The approval, based on KEYNOTE-B15 trial data, shows improved 2-year event-free survival (79.4% vs 66.2%) and overall survival (86.9% vs 81.3%) compared to chemotherapy. The combination is approved for use regardless of cisplatin eligibility. According to Merck, this offers a chemotherapy-free treatment option for MIBC patients in the EU.
