What was measured

Time to progression was defined as the time from the date of first dose of study treatment to the date of first documentation of PD + 1 day. Participants that did not experience PD will be censored at the last response assessment that is SD or better. PD: \>=25% increase from lowest value in:serum/urine M-component; difference between involved, uninvolved FLC levels; bone marrow plasma cell percent; new bone lesions/soft tissue plasmacytomas development/existing bone lesions/soft tissue plasmacytomas size rise; hypercalcaemia development. SD: not meeting criteria for CR, VGPR, PR, or PD. Participants that received Autologous Stem Cell Transplantation (ASCT) or an alternate cancer therapy were also be censored at the last response assessment that is, SD or better prior to initiation of therapy. Participants without response assessment will be censored at the date of first dose. TTP was analyzed using standard survival analysis techniques based on Kaplan-Meier estimates.

Analysis population: modified-intent-to-treat (mITT) population included all participants who received at least one dose of any study drug in Phase 2 or who received at least 1 dose of any study drug and were treated at the phase 2 dose level during Phase 1.

Groups in this outcome

Ixazomib 3 mg

Ixazomib 3 mg (MLN9708), capsules, orally, twice-weekly on Days 1, 4, 8, and 11, lenalidomide 25 mg capsules, orally, once daily on Days 1-14, dexamethasone 20 mg, capsules, orally, once daily on Days 1, 2, 4, 5, 8, 9, 11 and 12 in Cycle 1-8 and dexamethasone 10 mg, capsules, orally, once daily on Days 1, 2, 4, 5, 8, 9, 11 and 12 in Cycle 9-16 in 21-day treatment cycles for up to 16 cycles in the absence of disease progression or unacceptable toxicity as induction therapy during Phase 2. Participants with stable or responding disease continued receiving ixazomib (MLN9708) orally, twice weekly on Days 1, 4, 8, and 11 in 21-day treatment cycles as maintenance therapy at the dose tolerated at the end of induction until progressive disease or unacceptable toxicity. The maximum number of cycles received in this cohort was 83 cycles (approximately 2037 days).
