CheckMate 025 phase III trial: Outcomes by key baseline factors and prior therapy for nivolumab (NIVO) versus everolimus (EVE) in advanced renal cell carcinoma (RCC).
2016
498 Background: Based on assessment by an independent Data Monitoring Committee, a phase III trial of NIVO (n=410) vs EVE (n=411) in previously treated patients with advanced or metastatic RCC (NCT01668784) was halted early as it met its endpoint; superior overall survival (OS) was seen with NIVO vs EVE. We present outcomes by key baseline factors, prior therapy, and subsequent anticancer therapy. Methods: Patients with 1 or 2 prior anti-angiogenic therapies and measurable disease (RECIST v1.1) were randomized 1:1 to NIVO 3 mg/kg IV every 2 weeks or EVE 10 mg orally once daily. Primary endpoint was OS. A key secondary endpoint was objective response rate (ORR). Results: The Table shows OS and ORR by key baseline factors. Median follow-up was 17-18 mo. 77% and 23% of patients received 1 or 2 prior anti-angiogenic therapies, respectively, for advanced RCC, mainly sunitinib (63%) or pazopanib (32%). In patients who had prior sunitinib, median OS was 23.6 mo for NIVO vs 19.8 mo for EVE; in those who had prior...
