CheckMate 025 Randomized Phase 3 Study: Outcomes by Key Baseline Factors and Prior Therapy for Nivolumab Versus Everolimus in Advanced Renal Cell Carcinoma?

摘要

Abstract Background The randomized, phase 3 CheckMate 025 study of nivolumab ( n =410) versus everolimus ( n =411) in previously treated adults (75 male; 88 white) with advanced renal cell carcinoma (aRCC) demonstrated significantly improved overall survival (OS) and objective response rate (ORR). Objective To investigate which baseline factors were associated with OS and ORR benefit with nivolumab versus everolimus. Design, setting, and participants Subgroup OS analyses were performed using Kaplan-Meier methodology. Hazard ratios were estimated using the Cox proportional hazards model. Intervention Nivolumab 3mg/kg every 2 wk or everolimus 10mg once daily. Results and limitations The minimum follow-up was 14 mo. Baseline subgroup distributions were balanced between nivolumab and everolimus arms. Nivolumab demonstrated an OS improvement versus everolimus across subgroups, including Memorial Sloan Kettering Cancer Center (MSKCC) and International Metastatic Renal Cell Carcinoma Database Consortium risk groups; age Conclusion The trend for OS and ORR benefit with nivolumab for multiple subgroups, without notable safety concerns, may help to guide treatment decisions, and further supports nivolumab as the standard of care in previously treated patients with aRCC. Patient summary We investigated the impact of demographic and pretreatment features on survival benefit and tumor response with nivolumab versus everolimus in advanced renal cell carcinoma (aRCC). Survival benefit and response were observed for multiple subgroups, supporting the use of nivolumab as a new standard of care across a broad range of patients with previously treated aRCC. The trial is registered on ClinicalTrials.gov as NCT01668784. Take Home Message Consistent with the benefit demonstrated in previously treated patients with advanced renal cell carcinoma from CheckMate 025, an overall survival and objective response rate benefit with nivolumab versus everolimus was observed for multiple subgroups, including prognostic risk categories, age, number and sites of metastases, and prior therapies.
