    BackgroundCarfilzomib, lenalidomide, and dexamethasone (KRd) have been approved for the treatment of relapsed and refractory multiple myeloma (RRMM) based on ASPIRE clinical trial.AimAnalysis of efficacy and safety of KRd in routine clinical practice.Materials And MethodsThe prospective analysis included patients with MM who received at least one line of previous therapy. The inclusion criteria were relapse/progression; refractoriness; lack of very good partial response (VGPR) and more after the first line of therapy. Since February 2016, we used KRd like in ASPIRE trial, since October 2019, carfilzomib has been used at a dose of 56 mg/m2 on days 1, 8 and 15. Autologous hematopoietic stem cell transplantation (autoHSCT), consolidation (KRd) and maintenance therapy (Rd) were regarded as one line of therapy.Results And DiscussionWe evaluated 77 patients with median age at the time of diagnosis is 55 (3072) years. For 56% (n=43) of patients KRd was applied as the second line (group 1), for 44% (n=34) as the third and more (group 2). In 23/43 patients from group 1, an early change in therapy was made due to insufficient effectiveness (after 24 courses of VCD or PAD). KRd served as a "bridge" to autoHSCT in 25 (32%) patients (21 of 25 in group 1). Another 7 patients underwent collection of autoHSC (all from group 1). The overall response rate (ORR) was 80.5%, with 33.8% complete response (CR) and 26% VGPR. ORR in group 1 was 98% versus 65.6% in group 2; 24-month overall survival (OS) was 70%, progression free survival (PFS) 49.8%. In group 1, 24-month OS was 85.6% versus 50.0% in group 2, 24-month PFS was 67.8% versus 25.5% (p=0.01).ConclusionOur analysis confirmed the high efficiency of KRd in the treatment of RRMM in real-life practice. Early correction of therapy with insufficient effectiveness of the first line made it possible to implement the strategy of high-dose consolidation and autoHSCT in a larger percentage of patients with MM.
