What was measured

Response is defined as complete response (CR), very good partial response (VGPR) or partial response (PR). CR: Negative immunofixation on the serum and urine, disappearance of any soft tissue plasmacytomas and \<=5% plasma cells in 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 per 24 hours PR: * ≥ 50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥ 90% or to \< 200 mg per 24 hours * If followed by free light chain (FLC) only, a ≥ 50% decrease in the difference between involved and uninvolved FLC levels * If unmeasurable disease by serum M-protein, urine M-protein, and serum FLC at baseline, a ≥50% reduction in plasma cells provided baseline bone marrow percentage was ≥ 30% * If present at baseline, a ≥ 50% reduction in the size of soft tissue plasmacytomas

Analysis population: Among randomized patients who received treatment or observation

Groups in this outcome

Arm A (Lenalidomide; Phase III)

Patients receive lenalidomide PO QD on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Arm B (Observation; Phase III)

Patients undergo observation until progression to symptomatic myeloma.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
