“The results of this pivotal Phase 3 study are highly encouraging and showed a statistically significant survival benefit for the combination of KEYTRUDA with the antibody-drug conjugate enfortumab vedotin in cisplatin-eligible or cisplatin-ineligible patients with previously untreated locally advanced or metastatic urothelial carcinoma,” said Dr. Eliav Barr, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. “This is an important milestone, as many patients with advanced urothelial carcinoma still experience disease progression following chemotherapy. We look forward to sharing these data with the medical community and regulatory authorities.”
