What was measured

Minimal Residual Disease (MRD) was assessed for all participants as soon as they achieved CR/sCR, regardless of what phase they were on. MRD negativity is defined as the complete absence of plasma cells on bone marrow biopsy. MRD positivity is defined as the presence of residual plasma cells (\<5%) on bone marrow biopsy. The IMWG criteria were used to determine CR and sCR.

Analysis population: 28 participants achieved CR or sCR.

Groups in this outcome

Car-BiRD Therapy

Carfilzomib, Clarithromycin (Biaxin®), Lenalidomide (Revlimid®), and Dexamethasone (Decadron®) \[Car-BiRD\] Car Phase: carfilzomib: 45 mg/m2 IV on days 1, 2, 8, 9, 15 and 16 of each 28 day cycles. Dexamethasone: 20 mg orally on days 1, 2, 8, 9, 15 and 16 of a 28 day cycle, while receiving carfilzomib. BiRD Phase: Clarithromycin: 500 mg twice a day for each 28 day cycle of BiRD treatment. BiRD begins after carfilzomib treatment has been completed. Lenalidomide: 25 mg orally days 1-21 for each 28 day cycle of BiRD treatment. BiRD begins after carfilzomib treatment has been completed. Dexamethasone: 40 mg orally on days 1, 8, 15 and 22 of each 28 day cycle of BiRD treatment. BiRD begins after carfilzomib treatment has been completed. Maintenance Phase: Lenalidomide: 10 mg orally on days 1-21 or each 28 day cycle of maintenance. Maintenance begins after BiRD treatment has been completed.
