What was measured
OS was calculated as the time from randomization to death from any cause. OS was censored at the last date that the participant was known to be alive for participants who were alive at the time of analysis and for participants who were lost to follow-up before death was documented.
Analysis population: Intent to Treat population includes all participants who were randomized.
Groups in this outcome
Lenalidomide Plus Dexamethasone
Lenalidomide 25 mg by mouth (PO) daily (QD) on Days 1 to 21 and a matching placebo capsule QD on Days 22 to 28 of each 28-day cycle. Pulse dexamethasone 40mg PO QD on Days 1-4, 9-12, and 17-20 of each 28 day cycle for cycles 1 through 4. Beginning with Cycle 5, dexamethasone dosing schedule was reduced to 40mg PO QD on Days 1 to 4 every 28 days for the remaining cycles.
Placebo Plus Dexamethasone
Placebo PO daily on Days 1 to 28 of each 28 day cycle. Pulse dexamethasone 40 mg PO QD on Days 1-4, 9-12, and 17-20 of each 28-day cycle for Cycles 1 through 4. Beginning with Cycle 5, dexamethasone dosing schedule was reduced to 40 mg PO QD for Days 1-4 every 28 days. Participants with documented progressive disease were permitted to crossover to receive lenalidomide at the same doses mentioned. After the study was unblinded in August 2005 participants were given the option to add lenalidomide to their dexamethasone treatment regimen immediately or to add lenalidomide to their dexamethasone therapy at the time of disease progression.
