Abstract Disclosures


Background: Phase I/II studies showed the safety and efficacy of KRd and KCd in NDMM pts (Jakubowiak Blood 2012, Bringhen Blood 2014). Methods: NDMM pts ≤65 yrs were randomized (1:1:1; stratification ISS and age) to: 4 28-day KCd cycles (carfilzomib:20/36 mg/m2 IV d 1,2,8,9,15,16; cyclophosphamide 300 mg/m2 d 1,8,15; dexamethasone:20 mg d 1,2,8,9,15,16) followed by MEL200-ASCT and consolidation with 4 KCd cycles; or 4 28-day KRd cycles (carfilzomib and dexamethasone as above; lenalidomide:25 mg d 1-21) followed by MEL200-ASCT and 4 KRd cycles; or 12 KRd cycles. After the 4th induction cycle, all pts received Cyclophosphamide 2 g/m2, followed by PBSC collection. We report results of the first planned safety interim analysis on induction and mobilization and preliminary efficacy data. We pooled the 2 KRd groups since treatment was the same until mobilization. Data cut-off was October 30, 2016. Results: 281 pts were evaluated (KCd, n=94; KRd, n=187). The most frequent grade 3-4 AEs plus SAEs in both arms were hematological (mainly neutropenia) and infections (mainly pneumonia/fever); increased AST/ALT/GGT (mainly reversible) and dermatological (rash) AEs were higher in KRd; cardiac AEs were 2% (atrial fibrillation[1%]/ischemic heart disease[1%]) in KRd vs 1% (atrial fibrillation) in KCd. In KCd, 1 pt died of infection (not treatment-related) vs 3 in the KRd (2 cardiac arrest [1 not treatment-related],1 infection not treatment-related). In the KCd vs KRd arms, 99% vs 95% (P=0.44) of pts mobilized stem cells (median number of PBSC collected:9 vs 6x10^6CD34/Kg with KCd vs KRd); 10% vs 24% (P=0.01) required Plerixafor. Rate of ≥VGPR was 61% with KCd vs 74% with KRd (P=0.05). Conclusions: Safety profile was acceptable; more pts required plerixafor in KRd. Rate of VGPR was higher with KRd. Updated data on more patients will be presented at the meeting. NCT02203643.
