BACKGROUND: Enfortumab vedotin (EV) was approved for patients with metastatic urothelial carcinoma (mUC) who progressed after anticancer therapy on September 2021 in Japan. The association between the occurrence of EV-related side effects and clinical outcome remains to be elucidated.
METHODS: We identified 97 mUC patients treated with EV therapy at our five institutions from the date of approval to March 2023. The median follow-up period was 7.0 months. We retrospectively analyzed the efficacy and safety of EV.
RESULTS: The median age of the patients was 71 years old, 39% had PS of 1 or more, and 56.7% had primary tumor in upper urinary tract. Overall response rate (ORR) to EV therapy, median progression-free survival (PFS), and overall survival (OS) were 43.3%, 7.52 months, and 12.78 months, respectively. Any grade of treatment-related skin disorder, dysgeusia, peripheral neuropathy, gastrointestinal disorder, and hyperglycemia occurred in 61 (62.9%), 36 (37.1%), 34 (35.1%), 29 (29.9%), and 18 (18.6%) patients, respectively. The patients with EV-associated peripheral neuropathy had significantly higher ORR (58.8% vs. 34.9%, P = .032) and longer median PFS (8.05 vs. 6.31 months, P = .017) and OS (not reached vs. 11.57 months, P = .008, respectively) than those without. The occurrence of peripheral neuropathy after EV treatment and the presence of peritoneal dissemination were factors independently associated with PFS (hazard ratio = 0.46, P = .008 and hazard raito = 3.83, P = .004, respectively) and OS (hazard ratio = 0.30, P = .005 and hazard raito = 4.53, P = .002, respectively).
CONCLUSIONS: The occurrence of EV-related peripheral neuropathy might be associated with the efficacy of EV therapy in mUC patients.
