What was measured

CR rate was defined as the percentage of participants who achieve CR assessed by an IRC relative to the intent-to-treat (ITT) population during the treatment period. Percentage of participants with CR, as assessed by IMWG disease assessment criteria were reported. CR was defined as negative immunofixation of serum and urine along with the disappearance of any soft tissue plasmacytomas and \<5 % plasma cells (PC's) in bone marrow.

Analysis population: ITT population included all participants who were randomized.

Groups in this outcome

Placebo + LenDex

Participants who were randomly assigned to receive placebo matching capsule single oral dose on Days 1, 8 and 15 along with standard regimen of LenDex (lenalidomide 25 mg capsules orally on Days 1-21 and dexamethasone 40 mg tablets orally on Days 1, 8, 15 and 22) for the first 18 cycles (each cycle was of 28 days). Following Cycle 18, participants received 3.0 mg ixazomib matching placebo capsule as single oral dose on Days 1, 8 and 15 along with lenalidomide 10 mg capsules orally on Days 1-21 in each 28-day cycle until progressive disease or unacceptable toxicity, whichever comes first up to end of study (up to approximately 109 months).

Ixazomib + LenDex

Participants who were randomly assigned to receive Ixazomib 4.0 mg capsule single oral dose on Days 1, 8 and 15 along with standard regimen of LenDex (lenalidomide 25 mg capsules orally on Days 1-21 and dexamethasone 40 mg tablets orally on Days 1, 8, 15 and 22) for the first 18 cycles (each cycle was of 28 days). Following Cycle 18, participants received 3.0 mg ixazomib capsule as single oral dose on Days 1, 8 and 15 along with lenalidomide 10 mg capsules orally on Days 1-21 in each 28-day cycle until progressive disease or unacceptable toxicity, whichever comes first up to end of study (up to approximately 109 months).
