ABSTRACT
OBJECTIVES:
The JAVELIN Bladder 100 phase 3 trial showed that avelumab first-line maintenance + best supportive care significantly prolonged overall survival and progression-free survival versus best supportive care alone in patients with advanced urothelial carcinoma who were progression-free following first-line platinum-based chemotherapy. We report findings from J-AVENUE (NCT05431777), a real-world study of avelumab first-line maintenance therapy in Japan.METHODS:
Medical charts of patients with advanced urothelial carcinoma without disease progression following first-line platinum-based chemotherapy, who received avelumab maintenance between February and November 2021, were reviewed. Patients were followed until June 2022. The primary endpoint was patient characteristics; secondary endpoints included time to treatment failure and progression-free survival.RESULTS:
In 79 patients analyzed, median age was 72 years (range, 44-86). Primary tumor site was upper tract in 45.6% and bladder in 54.4%. The most common first-line chemotherapy regimen was cisplatin + gemcitabine (63.3%). Median number of chemotherapy cycles received was four. Best response to chemotherapy was complete response in 10.1%, partial response in 58.2%, and stable disease in 31.6%. Median treatment-free interval before avelumab was 4.9 weeks. With avelumab first-line maintenance therapy, the disease control rate was 58.2%, median time to treatment failure was 4.6 months (95% CI, 3.3-6.4), and median progression-free survival was 6.1 months (95% CI, 3.6-9.7).CONCLUSIONS:
Findings from J-AVENUE show the effectiveness of avelumab first-line maintenance in patients with advanced urothelial carcinoma in Japan in clinical practice, with similar progression-free survival to JAVELIN Bladder 100 and previous real-world studies, supporting its use as a standard of care.Palabras clave
