Study of CC-5013 to Evaluate Safety, Pharmacokinetics and Effectiveness for Japanese Patients With Symptomatic Anemia Associated With Myelodysplastic Syndrome With a Del(5)(q31-33) Abnormality.

A Multicenter, Single-arm Study to Assess the Safety, Pharmacokinetics and Efficacy of Lenalidomide in Japanese Subjects With Low- or Intern=Mediate-1-risk Myelodysplastic Syndromes (MDS) Associated With a Deletion 5 (q31-33) Abnormality and Symptomatic Anemia

The purpose of this clinical experience study is to determine whether CC-5013 is safe and effective (to include studying the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body [pharmacokinetics]) in Japanese subjects with low- or intermediate-1-risk MDS (IPSS risk categories) associated with a deletion 5(q31-33) abnormality and symptomatic anemia.

Inclusion Criteria:

• Must understand and voluntarily sign an informed consent form.
• Age ≥ 20 years at the time of signing the informed consent form.
• Must be able to adhere to the study visit schedule and other protocol requirements.
• Diagnosis of Myelodysplastic Syndrome (MDS) that meets International Prognostic Scoring System (IPSS) criteria for low- or intermediate-1-risk disease associated with a deletion 5(q31-33) abnormality
• Symptomatic anemia secondary to MDS defined as:Untransfused Hb level < 10.0 g/dL and a Functional Assessment of Cancer Therapy (FACT)-anemia subscale score of ≤ 74 or Transfusion dependent anemia

Exclusion Criteria:

• Pregnant or lactating females.
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study.
• Prior therapy with lenalidomide.
• Patients with any of the following laboratory abnormalities within 14 days of starting study drug: Absolute Neutrophil Count (ANC) < 750 cells/μL (0.75 x 10^9/L) Platelet count < 50,000/μL (50x10^9/L) Serum creatinine > 2.5 mg/dL Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) > 3.0 x Upper Limit of Normal (ULN)
