What was measured

Bone marrow response includes complete remission (CR) and partial remission (PR). Complete remission (CR): Bone marrow showing \< 5% myeloblasts with normal maturation of all cell lines, with no evidence for dysplasia. When erythroid precursors constitute \< 50% of bone marrow nucleated cells, the percent of blasts is based on all nucleated cells; when there are ≥ 50% erythroid cells, the percent blasts should be based on the non-erythroid cells. Partial remission (PR): All of the CR criteria (if abnormal prior to treatment), except blasts decreased by 50% over pre-treatment, or a less advanced Myelodysplastic Syndromes (MDS) World Health Organization (WHO) classification than pretreatment. Cellularity and morphology are not relevant.

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.
