Comparative efficacy of carfilzomib, lenalidomide, and dexamethasone (KRd) versus bortezomib, lenalidomide, and dexamethasone (VRd) in newly-diagnosed multiple myeloma: A systematic review and meta-analysis
AMERICAN JOURNAL OF HEMATOLOGY(2024)
Abstract
In view of the increasing data evaluating carfilzomib-based induction for newly-diagnosed multiple myeloma (NDMM), we conducted a systematic review and meta-analysis comparing the efficacy of carfilzomib/lenalidomide/dexamethasone (KRd) versus bortezomib/lenalidomide/dexamethasone (VRd). Three studies totaling 1597 patients (50% KRd-treated, 50% VRd-treated) were included. Despite similar survival outcomes and overall response rate compared with the VRd arm, KRd-treated subjects showed higher odds of achieving complete responses and measurable residual disease negativity. Among patients with high-risk cytogenetics (n = 348), KRd was associated with significant improvement in progression-free survival (HR = 0.70; 95% CI = 0.50-0.97; p = .03; I2 = 0%), suggesting carfilzomib-based induction may be preferable in this NDMM subpopulation.
