What was measured

The time to first worsening of the ECOG performance status was calculated as the time from randomization to the date of the first worsening compared with the last ECOG evaluation obtained prior to randomization. Data were censored at the last date that the participant was known to be unchanged or improved from before randomization for the participants who had not had worsened at the time of the analysis and for the patients who were lost to follow-up before worsening in the ECOG performance status was documented.

Analysis population: Intent to Treat includes all participants who were randomized to study drug; a total of six ECOG scores were missing at the time of the Aug 2005 cut-off.

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. 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. 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 for Days 1-4 every 28 days.
