Arm && Interventions

Group	Intervention	Description
Lenalidomide	Lenalidomide	Oral 10mg daily on Days 1-21 days every 28 days until disease progression/relapse or CC-5013 is permanently discontinued for any reason for up to 156 weeks (3 years).

Primary Outcome Measures

Name	Time	Method
Number of Participants With Adverse Events (AE)	After the first study dose until 28 days after completion of/discontinuation from the study (maximum time on study was 155 weeks).	An AE that resulted in any of the following outcomes was defined as a serious adverse event (SAE): * Death; * Life-threatening event; * Any inpatient hospitalization or prolongation of existing hospitalization; * Persistent or significant disability or incapacity; * Congenital anomaly or birth defect; * Any other important medical event. The investigator determined the relationship of an AE to study drug based on the timing of the AE relative to drug administration and whether or not other drugs, therapeutic interventions, or underlying conditions could provide a sufficient explanation for the event. The severity of an AE was evaluated by the investigator according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) (Version 3.0) where Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-threatening and Grade 5 = Death.

Secondary Outcome Measures

Terminal Half-life (T1/2) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, and 12 hours post-dose.	The apparent terminal half-life is the time required for plasma concentration to decrease by 50% after pseudo-equilibrium of distribution has been reached, and calculated as the natural logarithm of 2 (0.693) / Apparent terminal rate constant (λz).
Apparent Total Plasma Clearance (CL/F) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, and 12 hours post-dose.	Apparent total plasma clearance (CL/F) of lenalidomide after a single dose on Day 1 and multiple doses (Day 4).

Number of Participants With a Erythroid Response	Response was assessed every 28 days through Week 156.	Erythroid response was determined using the International Working Group (IWG) 2000 criteria, categorized as a major response or minor response. A major response in patients with transfusion-dependent anemia (receiving ≥ 4.5 units of red blood cell (RBC) transfusion during 56 consecutive days at Baseline) is defined as RBC transfusion independence accompanied by a ≥1.0 g/dL increase from Baseline in hemoglobin sustained for 56 days consecutively during the treatment period. In patients with transfusion-independent anemia with hemoglobin \< 10 g/dL at Baseline a major response is defined as a \> 2.0 g/dL increase from Baseline in hemoglobin sustained for consecutive 56 days. Minor response in patients with transfusion-dependent anemia defined as ≥ 50% decrease from Baseline in transfusion requirements sustained for consecutive 56 days, and in transfusion-independent patients as 1.0 to 2.0 g/dL increase from Baseline in hemoglobin sustained for consecutive 56 days.
Duration of Erythroid Response	From the first dose of study drug through Week 156	Duration of erythroid response was calculated as the time from the start of the first major or minor erythroid response to the end of the response. Similarly, duration of major erythroid response was calculated as the time from the start of the first major erythroid response to the end of the response. Response duration was censored at the last adequate assessment for patients who maintained response.
Area Under the Plasma Concentration-time Curve From Time Zero to the Last Measurable Concentration (AUCt) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, and 12 hours post-dose.

Time to Maximum Plasma Concentration (Tmax) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, and 12 hours post-dose.	Time to maximum observed plasma concentration of lenalidomide after a single dose on Day 1 and multiple doses (Day 4).
Area Under the Plasma Concentration-time Curve From Time Zero to Infinity (AUC∞) of Lenalidomide	Day 1 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12 and 24 hours post-dose.	Area under the plasma concentration-time curve from time zero to infinity (AUC∞) of lenalidomide after a single dose on Day 1.
Time to Erythroid Response	From the first dose of study drug through Week 156	Time to erythroid response was calculated as the time from the first dose of study drug to the start of the first major or minor erythroid response. Similarly, time to major erythroid response was calculated as the time from the first dose of study drug to the start of the first major erythroid response.
Area Under the Plasma Concentration-time Curve Over the Dosing Interval (AUCτ) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12 and 24 hours post-dose.	Area under the plasma concentration-time curve over the dosing interval (AUCτ) of lenalidomide after a single dose on Day 1 and multiple doses (Day 4).
Apparent Volume of Distribution (VzF) of Lenalidomide	Days 1 and 4 at predose and 0.5, 1, 1.5, 2, 3, 4, 6, 9, and 12 hours post-dose.	Apparent volume of distribution of lenalidomide after a single dose on Day 1 and multiple doses (Day 4).
Number of Participants With a Neutrophil Response	Response was assessed every 28 days through Week 156	Neutrophil response was determined using the IWG (2000) criteria. A major response for participants with a Baseline neutrophil count \< 1,500/mm\^3 is defined as a ≥ 100% increase or a ≥ 500/mm\^3 increase, whichever is greater, sustained for consecutive 56 days during the treatment period. A minor response for participants with a Baseline neutrophil count \< 1,500/mm\^3 is defined as a ≥ 100% increase, but an absolute increase \< 500/mm\^3, sustained for consecutive 56 days during the treatment period.
Number of Participants With a Cytogenetic Response	Response was assessed every 12 weeks through Week 156	Cytogenetic (chromosome structure) abnormalities were assessed by a central cytogenetic reviewer based on prints and cytogenetic reports of the bone marrow sample from the central laboratory. Cytogenetic response was determined using the IWG (2000) criteria and categorized as either a major response or minor response. Twenty metaphases were analyzed for the determination of cytogenetic response. A major response was defined as no detectable cytogenetic abnormality, if an abnormality was present at Baseline, sustained for consecutive 56 days during the treatment period. A minor response was defined as ≥ 50% reduction from Baseline in abnormal metaphases sustained for consecutive 56 days during the treatment period.
Change From Baseline in Percentage of Bone Marrow Erythroblasts	Baseline, at the end of Cycle 3 (Day 85) and Cycle 6 (Day 169).	Bone marrow morphology was assessed by the central hematologic reviewers based on the locally-prepared bone marrow smear slide and clot section.
Percentage of Bone Marrow Myeloblasts	Baseline, at the end of Cycle 3 (Day 85) and Cycle 6 (Day 169).	Bone marrow morphology was assessed by the central hematologic reviewers based on the locally-prepared bone marrow smear slide and clot section.
Percentage of Bone Marrow Promyelocytes	Baseline, at the end of Cycle 3 (Day 85) and Cycle 6 (Day 169).	Bone marrow morphology was assessed by the central hematologic reviewers based on the locally-prepared bone marrow smear slide and clot section.
Change From Baseline in Hemoglobin Concentration	Baseline and from Day1 until the maximum observed value (up to 155 weeks)	Change in hemoglobin concentration from Baseline to the maximum observed value during the major erythroid response period for major erythroid responders.
Number of Participants With a Platelet Response	Response was assessed every 28 days through Week 156	Platelet response was determined using the IWG (2000) criteria. Major response in patients with Baseline platelet count \< 100,000/mm\^3 is defined as a ≥ 30,000/mm\^3 increase sustained for consecutive 56 days during the treatment period. In platelet-transfusion-dependent patients at Baseline a major response is defined as stabilization of platelet counts and platelet transfusion independence sustained for consecutive 56 days during the treatment period. Minor response in patients with Baseline platelet count \< 100,000/mm\^3 is defined as a ≥ 50% increase in platelet count with an absolute increase \> 10,000/mm\^3 and \< 30,000/mm\^3 sustained for consecutive 56 days during the treatment period.
