What was measured

PFS2 was defined as the time from the date of randomization to the date of documentation of disease progression on the subsequent line of anticancer therapy, as assessed by the investigator in accordance with IMWG criteria, or death due to any cause, whichever occurs first.

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).
