Must have a documented diagnosis of B-cell CLL (IWCLL guidelines for the diagnosis and treatment of chronic lymphocytic leukemia, [Hallek M et al, 2008]).
Rai stage III or IV disease or requiring treatment for Rai stage I or II disease as defined in the Updated National Cancer Institute (NCI) guidelines (Hallek M et al, 2008). See Appendix B.
Patients must have received at least a purine-analogue containing regimen and have experienced relapse or have been refractory to the last therapy. Patients must not have received any therapy for B-CLL in the 4 weeks before this study or Alemtuzumab in the 6 months before initiating the treatment of this study.
Eastern Cooperative Oncology Group performance status of ≤ 2.
Absolute neutrophil count ≥ 2.000/μL
Platelet count ≥ 75/μL
Calculated creatinine clearance > 60 mL/min and creatinine < 1,5 mg/dl.
Total bilirubin < 2 mg/dl ( or > 2 mg/dl if Gilbert ?s Sindrome).
ALT and AST < 3x upper normal limit.
Female patients of Child-Bearing Potential (FCBP) must have 2 negative medically supervised pregnancy tests prior to starting the drug. They must agree to ongoing pregnancy testing during the course of the study, and after the end of the study therapy. They must adopt reliable methods of contraception and avoid becoming pregnant for at least 28 days after the discontinuation of the study drug.
Male patients must agree to use latex condoms during sexual contacts with female of child-bearing potential even if they have had a vasectomy, throughout study drug therapy, during any drug interruption and after cessation of study therapy. They must agree not to donate blood or semen for up to 28 days after study drug discontinuation.

Name Time Method Main Objective: The primary exploratory objective of this study is to identify clinical, hematological or molecular parameters able to predict response to lenalidomide treatment in relapsed/refractory CLL patients.;Secondary Objective: Secondary objectives of the study include:<br>Identification of predictive factors for early relapse or severe toxicity after lenalidomide treatment in relapsed/refractory CLL.<br>Evaluation of anti tumor activity, clinical efficacy and safety of an accelerated dose escalation procedure for lenalidomide treatment in patients with relapsed/refractory CLL.<br>Identification of predictive markers for Tumor Flare Reaction (TFR) or Tumor Lysis Syndrome and of mechanisms leading to TFR.;Primary end point(s): The primary endpoint is the Overall Response Rate.
