Enfortumab vedotin is a Nectin-4 directed antibody-drug conjugate approved in metastatic urothelial carcinoma following progression on a platinum-containing chemotherapy and immune checkpoint blockade. On-target dermatologic toxicity may occur from Nectin-4 expression in the skin. We highlight a case of Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis following enfortumab infusions that was ultimately fatal. The second case describes an erythema multiforme-like rash with interface dermatitis related to enfortumab. Dermatologic findings, immunohistochemistry studies, and immune profiling are detailed. These cases demonstrate the potentially catastrophic outcomes in some patients treated with enfortumab. Patients must be monitored for cutaneous toxicities with early involvement of dermatology and dermatopathology.
恩杂鲁胺是一种靶向Nectin-4的抗体药物偶联物,已被批准用于治疗在含铂化疗和免疫检查点阻断治疗后病情进展的转移性尿路上皮癌。皮肤中Nectin-4的表达可能会导致靶向性皮肤毒性。我们重点介绍了一例恩杂鲁胺输注后发生的史蒂文斯-约翰逊综合征/中毒性表皮坏死松解症,最终导致死亡。第二例描述了与恩杂鲁胺相关的多形红斑样皮疹伴界面性皮炎。详细介绍了皮肤表现、免疫组织化学研究和免疫分析。这些病例表明,一些接受恩杂鲁胺治疗的患者可能会出现灾难性后果。必须对患者进行皮肤毒性监测,皮肤科和皮肤病理学应尽早介入。
