Merck says EU CHMP backs Keytruda — Padcev perioperative use in resectable muscle — invasive bladder cancer

Merck reported Phase 3 KEYNOTE-B15 results supporting perioperative Keytruda with Padcev in resectable muscle-invasive bladder cancer. Results were already reported in the CHMP briefing; no future scientific meeting presentation was specified. Trial showed fewer disease events and longer survival versus standard neoadjuvant chemotherapy followed by surgery. EU regulators issued a positive CHMP opinion; European Commission decision expected in Q4 2026. U.S. regulators cleared the regimen in July 2026, positioning it as a key growth driver across earlier-stage bladder cancer.
