Approval is based on results from the Phase 3 KEYNOTE-A39 trial, which demonstrated a superior overall survival benefit with KEYTRUDA plus Padcev versus platinum-based chemotherapy (gemcitabine plus cisplatin or carboplatin) in these patients
Approval expands the use of KEYTRUDA plus Padcev for locally advanced or metastatic urothelial cancer regardless of cisplatin eligibility
RAHWAY, N.J.--(BUSINESS WIRE)-- Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced the U.S. Food and Drug Administration (FDA) has approved KEYTRUDA, Merck’s anti-PD-1 therapy, in combination with Padcev (enfortumab vedotin-ejfv), an antibody-drug conjugate, for the treatment of adult patients with locally advanced or metastatic urothelial cancer.

The approval is based on data from the Phase 3 KEYNOTE-A39 trial (also known as EV-302) in 886 patients with locally advanced or metastatic urothelial cancer, which was conducted in a research collaboration with Pfizer (previously Seagen) and Astellas.
