Objective To evaluate the efficacy and safety of vibegron in patients with overactive bladder (OAB) in real-world clinical practice in Japan. Methods This multicenter, prospective, non-controlled study consecutively enrolled patients with OAB determined by an OAB symptom score (OABSS) of three points or more and a question 3 (urgency) score of two points or more. A total of 212 patients from 43 institutions were recruited from January 2019 through March 2020. Vibegron, 50 mg, was administrated daily for 8 weeks as first-line monotherapy (first-line group, FL), monotherapy switching from antimuscarinics (post-antimuscarinic group, PA) or mirabegron (post-mirabegron group, PM) and combination therapy with antimuscarinics (add-on group). The OABSS was collected at baseline and every 2 weeks. Adverse events were recorded at every visit. Results Of the 212 patients registered, 188 (male 76, female 112) were eligible for analysis (124 in the FL group, 27 in PA, 29 in PM, and eight in the add-on group). The add-on group was excluded from further analysis due to its small number. The OABSS (mean ± SD) showed significant improvement in all groups (FL; 8.8 ± 2.5, 3.8 ± 2.8, PM; 9.4 ± 2.2, 4.5 ± 4.0, PM; 8.9 ± 2.5, 4.7 ± 3.3 at 0 and 8 weeks, respectively). The overall incidence of adverse events was 25%. No grade 3 or higher adverse events were observed. Conclusions In the real-world clinical setting, vibegron is effective and well-tolerated by OAB patients, including those switching therapy from antimuscarinics and mirabegron.

We report the case of a patient who achieved complete remission (CR) of cisplatin-refractory metastatic pure seminoma after treatment with high-dose carboplatin and etoposide (CE) with peripheral blood stem cell transplantation as fourth-line chemotherapy. A 38-year-old man was diagnosed with advanced pure seminoma (pT3N3M1aS3). In the international germ cell consensus classification, his prognosis was classified as intermediate. He was treated with high-dose CE as fourth-line chemotherapy after treatment with BEP, VeIP, and TIN. After two cycles of high-dose CE, the concentrations of T-HCG and other tumor markers showed normal levels. A CT scan and PET–CT showed that the lymph node swelling had disappeared and there was no uptake. The CR has continued for 27 months after the treatment. High-dose CE might be less toxic and have a better prognostic outcome than other treatments as salvage chemotherapy for patients with cisplatin-refractory advanced testicular cancer.
