Enfortumab vedotin and pembrolizumab: redefining the standard of care for previously untreated advanced urothelial cancer

Abstract
Combination treatment with Enfortumab vedotin (EV), an antibody drug conjugate targeting Nectin-4 with a monomethyl auristatin E (MMAE) payload, and pembrolizumab, a programmed death 1 (PD-1) inhibitor, has become the new standard of care for previously untreated locally advanced or metastatic urothelial carcinoma. In the recently published phase III study, EV-302, EV and pembrolizumab demonstrated improved outcomes compared to platinum-based chemotherapy, including objective response rate, progression free survival, and an unprecedented median overall survival of 33.8 months (versus 15.9 months; hazard ratio for death 0.51; 95% confidence interval 0.43–0.61; p < 0.00001). We reviewed the mechanism of action, clinical efficacy, exploratory biomarkers, and safety profile of EV and pembrolizumab as monotherapies and combination in urothelial cancer.
