RESUMO
OBJECTIVES: This study aimed to evaluate the efficacy and safety of Vibegron for the treatment of residual overactive bladder (OAB) symptoms after laser vaporization of the prostate (photo-selective vaporization of the prostate, contact laser vaporization of the prostate, and thulium laser vaporization). METHODS: This randomized, open-label, parallel-group, single-center superiority trial with a 12-week observation (jRCTs071190040) enrolled male patients with OAB aged 40 years or older who had undergone laser vaporization of the prostate for not less than 12 weeks and not more than 1 year earlier. Patients were allocated to receive Vibegron 50 mg once daily or follow-up without treatment for 12 weeks. RESULTS: Forty-seven patients were enrolled between January 2020 and March 2023. The median age (interquartile range) was 75.5 (72.5-78.5) years for the Vibegron group and 76.5 (71.0-81.0) years for the control group. The intergroup difference in the mean change (95% confidence interval) in the 24-hour urinary frequency at 12 weeks after randomization was -3.66 (-4.99, -2.33), with a significant decrease for the Vibegron group. The Overactive Bladder Symptom Score, International Prostate Symptom Score, IPSS storage score, and Overactive Bladder Questionnaire score significantly improved for the Vibegron group. Voided volume per micturition also increased for the Vibegron group. CONCLUSIONS: The administration of 50 mg of Vibegron once daily for 12 weeks showed significant improvement compared with follow-up without treatment in bladder storage (OAB) symptoms after laser vaporization of the prostate for symptomatic benign prostatic hyperplasia.

Subtype of urothelial carcinoma (SUC), defined here as urothelial carcinoma with any histologic subtype or divergent differentiation, is a clinically aggressive disease. However, the efficacy of enfortumab vedotin (EV) against SUC remains unclear. Hence, this study aimed to assess the oncological outcomes of patients with SUC treated with EV for metastatic disease. We retrospectively evaluated consecutive patients with advanced lower and upper urinary tract cancer who received EV after platinum-based chemotherapy and immune checkpoint blockade therapy at six institutions. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared between patients with pure urothelial carcinoma (PUC) and those with SUC. We identified 44 and 18 patients with PUC and SUC, respectively. Squamous differentiation was the most common subtype element, followed by glandular differentiation and sarcomatoid subtype. Although patients with SUC had a comparable ORR to those with PUC, the duration of response for SUC was short. Patients with SUC had poorer PFS than those with PUC; however, no significant difference was observed in OS. Multivariate analysis revealed that SUC was significantly associated with shorter PFS. Although the response of metastatic SUC to EV was similar to that of PUC, SUC showed faster progression than PUC.

BACKGROUND/AIM: The clinical outcomes associated with cutaneous toxicity and changes in the renal function of patients receiving enfortumab vedotin (EV) for advanced urothelial carcinoma (UC) is unclear. PATIENTS AND METHODS: We retrospectively analyzed the relationship between clinical outcomes and EV-related cutaneous toxicity, and the influence on the renal function in 58 patients with advanced UC who received EV after the failure of platinum-based chemotherapy and immune checkpoint inhibitors from December 2021 to July 2023. RESULTS: There were no differences in the overall response and disease control rates between patients with any grade of EV-related cutaneous toxicity and without (p=0.605 and p>0.99, respectively) nor of grade ≥3 (p>0.99 and p=0.173, respectively). Progression-free survival was not significantly associated with EV-related cutaneous toxicity of any grade (5.4 vs. 5.6 months, p=0.557) nor of grade ≥3 (2.7 vs. 5.6 months, p=0.053). Overall survival was not significantly associated with EV-related cutaneous toxicity of any grade (11.8 vs. 8.9 months, p=0.389), nor of grade ≥3 (4.6 vs. 11.4 months, p=0.168). The incidence of EV-related cutaneous toxicity of any grade was significantly higher in patients with any grade of ICI-related cutaneous toxicity (88.9% vs. 36.7%, p=0.008). There was no significant difference in the serum creatinine levels after EV treatment (p=0.211). Divided into two groups according to their renal function, using a serum creatinine cut-off of 2 mg/dl, there were no significant changes after EV treatment in either group (p=0.187 and p=0.938). CONCLUSION: EV-related cutaneous toxicity did not affect clinical outcomes, although it occurred in patients who experienced immune checkpoint inhibitor-related cutaneous toxicity. EV did not affect renal function.

BACKGROUND/AIM: The efficacy, safety, and liver toxicity of enfortumab vedotin (EV) for elderly advanced urothelial carcinoma (UC) patients and patients with a poor performance status (PS) are unclear. PATIENTS AND METHODS: We retrospectively analyzed the efficacy, safety, and liver toxicity of EV in elderly patients and patients with a poor PS between December 2021 and August 2023. RESULTS: Sixty-two patients (≥75 years old, n=22; PS≥2, n=10) were enrolled. Patients with PS≥2 had significantly lower albumin levels than those with PS<2 (p=0.023). The objective response and disease control rates did not differ significantly between patients <75 and ≥75 years old (p=0.598 and p=0.769, respectively) or between those with PS<2 and PS≥2 (p>0.99 and p=0.178, respectively). Progression-free survival (PFS) and overall survival (OS) were not significantly different in patients <75 years and ≥75 years (p=0984, 0.368). A significant difference in PFS (p=0.047) but not OS (p=0.086) was observed between the PS<2 and PS≥2 groups. The rates of any-grade and severe (grade ≥3) adverse events did not differ significantly between patients <75 and ≥75 years (p=0.471, p=0.136) or between PS<2 and PS≥2 groups (p>0.99, 0.99). Aspartate aminotransferase (AST) levels significantly increased, but alanine aminotransferase levels did not, following EV treatment (p<0.001). Multivariate analyses revealed that the albumin level was an independent prognostic factor (hazard ratio=0.159; p<0.001). CONCLUSION: EV demonstrated similar efficacy and safety in elderly and younger patients with advanced UC. In patients with a poor PS, although the safety was similar, survival was significantly worse in terms of PFS, while the AST levels were significantly elevated.

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

INTRODUCTION: To evaluate the organ-specific therapeutic effect of enfortumab vedotin (EV) after chemotherapy and immunotherapy failed for advanced urothelial carcinoma. MATERIALS METHODS: At 6 institutions between December 2021 and July 2023, we retrospectively analyzed patients with metastatic upper and lower urinary tract cancer who received EV monotherapy after platinum-based chemotherapy and immune checkpoint blockade therapy. Objective response rate (ORR) and organ-specific response rate (OSRR) were evaluated according to the Response Evaluation Criteria in Solid Tumors, version 1.1. RESULTS: This study analyzed 58 patients with 210 tumor lesions, of which 24% were females and 48% had upper urinary tract cancer. The ORR and disease control rate were 53.5% and 74.1%. Moreover, we found 15 target lesions in the primary site, 7 in local recurrence, 93 in the lymph nodes, 46 in the lung, 29 in the liver, and 20 in the bone, with OSRRs of 40%, 71.4%, 61.1%, 70.6%, 90.9%, and 18.2%, respectively. Over time from baseline, the reduction rate (median) in tumor burden was 50% or more in the lymph node, lung, and liver metastases. CONCLUSION: The organ-specific tumor response to EV in patients with metastatic urothelial carcinoma was almost favorable. The antitumor activity of EV monotherapy may be less in bone metastasis than in other organ sites. Conversely, EV showed remarkably high efficacy against liver metastasis.
