Merck & Company IncCHMP positive opinion recommends approval of Keytruda plus Padcev for expanded muscle-invasive bladder cancer indication, advancing EU regulatory path.
Merck announced that the European Medicines Agency's Committee for Medicinal Products for Human Use has issued a positive opinion recommending approval of Keytruda in combination with Pfizer's Padcev for an expanded bladder cancer indication. The CHMP recommended Keytruda and its subcutaneous formulation, Keytruda Qlex, each in combination with Padcev as neoadjuvant treatment and then continued after radical cystectomy as adjuvant treatment in adult patients with resectable muscle-invasive bladder cancer. The opinion was based on data from the phase III KEYNOTE-B15 study, conducted in collaboration with Pfizer and Astellas, and will now be reviewed by the European Commission, with a final decision expected in the fourth quarter of 2026. If approved, the regimen would become the first and only PD-1 inhibitor plus antibody-drug conjugate combination approved for patients with muscle-invasive bladder cancer regardless of cisplatin eligibility in Europe. The same regimen was approved by the FDA for the same indication in July 2026, while a separate cisplatin-ineligible MIBC approval was granted by the European Commission in June 2026 based on the phase III KEYNOTE-905 study. Keytruda generated $16.40 billion in sales in the first half of 2026, up 4.2% year over year, while Padcev, added from the December 2023 Seagen acquisition, generated $1.26 billion in the first half of 2026, up 30% year over year.
