ABSTRACT Background Recently, a plethora of novel systemic agents have been incorporated into the therapeutic armamentarium advanced urothelial carcinoma (aUC). The antibody–drug conjugate (ADC), enfortumab vedotin (EV), has demonstrated relevant clinical benefit in patients with aUC refractory to platinum and immune‐checkpoint inhibitor (ICI) therapy. Our study provides retrospective, international, real‐world analysis comparing effectiveness EV chemotherapy this setting. Methods data were extracted from medical records treated or following pembrolizumab for recurrent progressive after platinum‐based chemotherapy. Patients assessed overall survival (OS), progression‐free (PFS), response rate (ORR) duration (DoR). Results included 247 (88, 36%) (159, 64%). Median OS was 9.1 months (95%CI 7.2–10.7) population, 13.6 10.0–31.0) receiving 6.8 6.0–8.9) ( p < 0.001). not affected by primary tumour site histology, metastatic sites, type first pembrolizumab. In cohort, median PFS significantly longer (8.8 [95%CI 6.5–17.0] vs. 3.0 2.6–3.7]) ORR higher (56% 23%) than cohort. Conclusions results our international confirm sequential strategy who received prior anti‐PD‐1 pembrolizumab, regardless commonly considered prognostic factors.

Background/Aim: This study retrospectively evaluated whether enfortumab vedotin (EV) monotherapy is effective as a late-line treatment according to prior type in patients with advanced urothelial carcinoma (UC). Patients and Methods: We assessed consecutive from the Uro-Oncology Group Kyushu population lower upper urinary tract cancer treated EV after platinum-based chemotherapy immune checkpoint inhibitor therapy failure between December 2021 March 2024. In particular, receiving avelumab maintenance or pembrolizumab before for UC were analyzed compared response rate, progression-free survival (PFS), overall (OS). Results: Of 80 enrolled patients, 31 49 received therapy, respectively. The groups had comparable objective rates (48.4% vs. 44.9%, p=0.820) disease control (77.4% 67.3%, p=0.448). These two showed no significant difference PFS initiation of (median: 6.4 months 4.2 months, p=0.184); meanwhile, group better OS than 16.0 10.2 p=0.019). Moreover, median first-line was longer (40.3 24.7 p=0.054). On multivariate analysis, reduced mortality risk by 47% (95% confidence interval=0.27-1.03; p=0.059). Conclusion: provides favorable outcomes UC.
