What was measured

The definition of minor erythroid response: the mean hemoglobin is sustained 1.0 to 2.0 g/dL above the baseline value for a minimum of 8 weeks; or a 50% or greater decrease in 8-week red blood cell transfusion requirements compared to baseline.

Analysis population: Evaluable patients randomized to either arm A or arm B

Groups in this outcome

Arm A (Lenalidomide; Randomization)

Patients receive lenalidomide PO QD on days 1-21.

Arm B (Lenalidomide + Epoetin Alfa; Randomization)

Patients receive lenalidomide PO QD on days 1-21 and epoetin alfa SC once weekly.

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