What was measured

Response duration was defined as the time from first documented evidence of at least a partial response (sCR+CR+VGPR+PR\]), until confirmed disease progression or death. DOR was calculated from product-limit (Kaplan-Meier) method for censored data. This is an event-driven (events of disease progression and death) outcome measure. At the time of data cut-off, there were an insufficient number of events from the censored data to be able to estimate certain parameters (e.g. medians). Full Range is the minimum and maximum of the observed duration of response. The data cutoff date was July 9, 2018.

Analysis population: The analysis population included all randomized participants who demonstrated at least a partial response. 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.
