Time frame
Cycle 1 Day 1 up to approximately 12 months (cycle = 28 days); median treatment duration for the twice-weekly arm was 47.00 weeks and for the once-weekly arm was 47.14 weeks.

What was measured

MRD\[-\]CR was defined as achievement of CR or better by IRC per IMWG-URC and achievement of MRD negativity as assessed by next generation sequencing method at a 10\^-5 threshold over the duration of the study. The 95% CIs for percentages were estimated using the Clopper-Pearson method.

Analysis population: The ITT population included all randomized participants.

Groups in this outcome

Twice-weekly KRd 20/27 mg/m^2

Carfilzomib was administered twice-weekly intravenously as a 10 ± 5 minute infusion using an infusion pump on Days 1, 2, 8, 9, 15, and 16 of each 28-day cycle. The dose was 20 mg/m\^2 on Days 1 and 2 of Cycle 1 and 27 mg/m\^2 beginning on Day 8 of Cycle 1 and thereafter. Participants also received lenalidomide 25 mg daily orally on Days 1 to 21 of each cycle and dexamethasone 40 mg weekly orally or intravenously. Participants were treated for up to 12 28-day cycles.

Once-weekly KRd 20/56 mg/m^2

Carfilzomib was administered once-weekly intravenously as a 30 ± 5 minute infusion using an infusion pump on Days 1, 8, and 15 of each 28-day cycle. The dose was 20 mg/m\^2 on Day 1 of Cycle 1 and 56 mg/m\^2 beginning on Day 8 of Cycle 1 and thereafter. Participants also received lenalidomide 25 mg daily orally on Days 1 to 21 of each cycle and dexamethasone 40 mg weekly orally or intravenously. Participants were treated for up to 12 28-day cycles.
