Concurrent corticosteroids used for medical conditions other than MDS is allowed provided subject is on a stable or decreasing dose for =1week prior to study entry 5. Prior thalidomide allowed 6. Documented diagnosis of MDS that meets IPSS criteria for low- to intermediate-1-risk disease and has an associated del 5q[31] cytogenetic abnormality (the deleted chromosomal region must include 5q[31] 7. RBC transfusion-dependent anemia defined as not having any consecutive 56 days without a RBC transfusion within at least the immediate 112 days (4 months). Note: A 112 day documented transfusion history is required for subjects to enter the double-blind phase of the study. Double-blind randomization Phase: As point 1-3, 6 and 7 above, plus: 1. Baseline RBC transfusion requirement has been calculated 2. Female subjects of childbearing potential must: - Understand that the study medication could have a potential teratogenic risk - Agree to use, and be able to comply with, effective contraception without interruption, 28 days before starting study drug, throughout study drug therapy (including dose interruptions) and for 28 days after the end of study drug therapy, even if she has amenorrhoea. This applies unless the subject commits to absolute and continued abstinence confirmed on a monthly basis. The following are effective methods of contraception: implant, Levonorgestrel-releasing intrauterine system, Medroxyprogesterone acetate depot, Tubal sterilisation, Sexual intercourse with a vasectomised male partner only; vasectomy must be confirmed by two negative semen analyses, Ovulation inhibitory progesterone-only pills (i.e., desogestrel). - Agree to have a medically supervised pregnancy test with a minimum sensitivity of 25 IU/ml not more than 3 days from the start of study medication once the subject has been on effective contraception for at least 28 days. This requirement also applies to females of childbearing potential who practice complete and continued abstinence. - Agree to have a medically supervised pregnancy test every 28 days including 28 days after the end of study treatment, except in the case of confirmed tubal sterilization. These tests should be performed not more than 3 days before the start of next treatment. This requirement also applies to females of childbearing potential who practice complete and continued abstinence. 8. Male subjects must: - Agree to use condoms throughout study drug therapy, during any dose interruption and for 7 days after cessation of study therapy if their partner is of childbearing potential and has no contraception. - Agree not to donate semen during study drug therapy and for 7 days after end of study drug therapy. 9. All subjects must: - Agree to abstain from donating blood while taking study drug therapy and for 7 days following discontinuation of study drug therapy. - Agree not to share study medication with another person and to return all unused study drug to the investigator
