What was measured

Disease control rate was defined as the percentage of participants who achieved confirmed sCR, CR, VGPR, PR, or have demonstrated SD for at least 12 weeks prior to any evidence of progression. CR = negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow; VGPR = serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24 hr; PR = ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 hours; SD = not meeting the criteria for CR, VGPR, PR, or PD; PD = development of new bone lesions or soft tissue plasmacytomas or on a definite increase in the size of existing bone lesions or soft tissue plasmacytomas. Data cutoff date was July 9, 2018.

Analysis population: The analysis population included all randomized participants. Participants were included in the treatment group to which they were randomized.

Groups in this outcome

Pembrolizumab + Lenalidomide + Dexamethasone

Participants received pembrolizumab 200 mg intravenously (IV) on Day 1 of each 21-day cycle PLUS lenalidomide 25 mg orally (PO) on Days 1 to 21 of each 21-day treatment cycle, and dexamethasone 40 mg PO on Days 1, 8, 15 and 22 of each 28-day cycle for up to 18 cycles.

Lenolidomide + Dexamethasone

Participants received lenalidomide 25 mg PO on Days 1 to 21 of each 21-day treatment cycle, and dexamethasone 40 mg PO on Days 1, 8, 15 and 22 of each 28-day cycle for up to 18 cycles.
