Management of Dermatologic Events Associated With the Nectin-4-directed Antibody-Drug Conjugate Enfortumab Vedotin. (26th February 2022) - Lacouture, Mario E
Abstract: Enfortumab vedotin is a first-in-class Nectin-4-directed antibody-drug conjugate approved by the US Food and Drug Administration for the treatment of patients with locally advanced or metastatic urothelial cancer (la/mUC) previously treated with a platinum-based chemotherapy and a programmed death receptor-1/programmed death-ligand 1 (PD-1/L1) inhibitor, or patients with la/mUC who are ineligible for cisplatin-based chemotherapy and have previously received one or more prior lines of therapy. Enfortumab vedotin is the only drug to have demonstrated survival benefit versus chemotherapy in a randomized controlled trial in patients with la/mUC previously treated with platinum-based chemotherapy and a PD-1/L1 inhibitor. The development of dermatologic events following the administration of enfortumab vedotin is anticipated given the expression of Nectin-4 in epidermal keratinocytes and skin appendages (eg, sweat glands and hair follicles). There is the potential for rare but severe and possibly fatal cutaneous adverse reactions, including Stevens-Johnson syndrome and toxic epidermal necrosis, as described in the boxed warning of the US prescribing information for enfortumab vedotin. This manuscript describes the presumed pathophysiology and manifestations of dermatologic reactions related to enfortumab vedotin, and presents recommendations for prevention and treatment, to provide oncologists and other healthcare providers with an awareness of these potential adverse events to best anticipate and manage them. Abstract : Enfortumab vedotin is a Nectin-4-directed antibody-drug conjugate approved by the US FDA for the treatment of patients with locally advanced or metastatic urothelial cancer. This article describes dermatologic reactions related to enfortumab vedotin and presents prevention and treatment recommendations.
