Complete Response to Enfortumab Vedotin in a Hemodialysis Patient with Metastatic Urothelial Carcinoma: A Case Report.

Enfortumab vedotin (EV) is an antibody-drug conjugate and a promising agent for metastatic urothelial carcinoma (mUC). However, evaluations in end-stage renal disease patients undergoing hemodialysis are unreported. Here, we report such a case. A 74-year-old woman with mUC, on hemodialysis for complete urinary tract extirpation, was diagnosed with multiple pulmonary metastases after treatment with gemcitabine-carboplatin followed by pembrolizumab. As third-line therapy, she received a standard dose of EV. She achieved complete response after 2 cycles without grade 3 or higher adverse events, demonstrating the utility of EV in this setting.
