What was measured

OS was defined as the time from randomization to death due to any cause. OS was calculated from the product-limit (Kaplan-Meier) method for censored data. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. This is an event-driven (events of 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). The database cutoff date was August 3, 2020.

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.
