9. Patients who are on epoetin alfa or darbepoetin prior to enrollment will be allowed to enroll if they have failed such therapy, failure defined as transfusion requiring despite >/= 6 weeks of epoetin alfa at dose of 40,000 units/week and darbepoetin alfa at dose of 150 mcg/ 2 week.

10. Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10-14 days prior to and again within 24 hours of prescribing lenalidomide and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 4 weeks before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing.
11. continued from #10 Men must agree to use a latex condom during sexual contact with a female of child bearing potential even if they have had a successful vasectomy.

Exclusion Criteria:

1. Clinically significant anemia owing to iron, B12, or folate deficiencies.

3. Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking lenalidomide)
4. Concomitant use of steroids will not be allowed unless used for premedication in preparation for transfusions, treatment of hypersensitivity reaction related to lenalidomide or any underlying medical condition other than MDS (e.g. Chronic Obstructive Pulmonary Disease (COPD)).
5. Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
6. Use of any other experimental drug or therapy within 28 days of baseline.
7. Known hypersensitivity to thalidomide.
