Impact of Cumulative Dose of Carfilzomib in Combination with Lenalidomide and Dexamethasone in Relapsed Refractory Myeloma Patients: A Retrospective Real Life Survey of the Sicilian Myeloma Network

Abstract Background: Triplet-based lenalidomide plus dexamethasone (Rd) combinations have become the new standard of care for early relapse and refractory multiple myeloma (RRMM). Carfilzomib is a novel selective proteasome inhibitor (PI) with high efficacy in RRMM. The ASPIRE phase 3 trial showed the superiority of carfilzomib-based triplet (KRd compared to Rd), leading to approval of K for RRMM. However, little is known about safety and efficacy of KRd outside a clinical trial context. Experimental design and aims: In 11 Sicilian Centers belonging to the Sicilian Myeloma Network, from November 2016, when KRd regimen was approved in Italy, to June 2018, 103 consecutive RRMM patients (previ…
