BACKGROUND/AIM: This study retrospectively investigated the impact of enfortumab vedotin (EV) monotherapy on the oncological outcome, safety profile, and health-related quality of life (HRQoL) in patients with metastatic urothelial carcinoma.
PATIENTS AND METHODS: We assessed 26 consecutive patients who had received EV monotherapy after failure of platinum-based chemotherapy and immune checkpoint blockade therapy at our single institution from December 2021 to January 2023. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), incidence of adverse events (AEs), and EORTC QLQ-C30 as an HRQoL instrument were evaluated.
RESULTS: The ORR and DCR were 57.7% and 80.8%, respectively. EV was effective regardless of the patient and tumor characteristics, including the efficacy of previous systemic therapy, performance status, number of Bellmunt risk factors, and presence of variant histology. With a median follow-up time of 7.5 months, the median durations of PFS and OS were 5.4 months and 10.3 months, respectively. Grade ≥3 AEs included neutropenia (15.4%), fatigue (7.7%), appetite loss (7.7%), rash (3.8%), febrile neutropenia (3.8%), hyperglycemia (3.8%), and interstitial pneumonia (3.8%). AEs resulting in withdrawal of EV, interruption of EV, and dose reduction occurred in two (7.7%), nine (34.6%), and 13 patients (50.0%), respectively. The EORTC QLQ-C30 scores from baseline to post-EV introduction remained stable.
CONCLUSION: EV monotherapy demonstrated promising anti-tumor activity and tolerability in patients with metastatic urothelial carcinoma.
