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: All registered patients in the phase II part

Groups in this outcome

Arm A (Lenalidomide; Phase II)

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

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