What was measured

PFS was defined as the time from the date of first dose of study drug to the first occurrence of PD as evaluated by the investigator or death from any cause, whichever occurred first. PD was defined as ≥25% increase from lowest value in serum M component or urine M-component; difference between involved and uninvolved free light chain (FLC) levels (absolute increase \>10 milligrams per deciliter \[mg/dL\]); bone marrow plasma cell percent ≥10%; new bone lesions or soft tissue plasmacytomas development or definite increase in existing bone lesions/soft tissue plasmacytomas size; hypercalcaemia development.

Analysis population: Efficacy Population included all participants who received ixazomib treatment for the duration of their study participation. As prespecified in the SAP, the Efficacy Population contained only one arm i.e., Ixazomib (efficacy outcomes data for the participants who received placebo before Protocol Amendment 8 was not collected per statistical analysis plan), thus data is presented accordingly.

Groups in this outcome

Ixazomib

Participants received ixazomib 3 mg, capsules, orally, once on Days 1, 8, and 15 for Cycles 1 through 4, during which if the participants tolerated the initial dose, the dose was escalated to ixazomib 4 mg, capsules, orally, once on Days 1, 8, and 15 for Cycles 5 through 26, or until documented progressive disease (PD) or intolerable toxicity, whichever occurred first (cycle length=28 days).
