NCT00774345

  Purpose

The purpose of this study is to determine if lenalidomide (Revlimid®) is safe and effective as a maintenance therapy at improving further the quality of the response you achieved with your last therapy and at prolonging the duration of your response. This study will compare the effects (good and bad) of lenalidomide with the dummy drug.

Inclusion Criteria:

  1. Must understand and voluntarily sign an informed consent form.
  2. Must be greater than or equal to 18 years at the time of signing the informed consent form.
  3. Must be able to adhere to the study visit schedule and other protocol requirements.
  4. Must have a documented diagnosis of B-cell CLL (IWCLL guidelines for the diagnosis and treatment of chronic lymphocytic leukemia [Hallek, 2008]).
  5. Must have been treated with one of the following in first and/or second line:

    • a purine analog-containing regimen
    • a bendamustine-containing regimen
    • an anti-CD20 antibody-containing regimen
    • a chlorambucil-containing regimen
    • an alemtuzumab-containing regimen (for those subjects with a 17p deletion)
  6. Must have achieved a minimum response of partial response (PR, nPR, CRi, CR, and MRD-negative CR) (IWCLL guidelines for the diagnosis and treatment of chronic lymphocytic leukemia [Hallek, 2008]) following completion of second-line induction therapy prior to randomization (documentation of response status must be available). Second-line induction therapy must be documented to have been of sufficient duration.
  7. Must have completed last cycle of second-line induction no less than 8 weeks (56 days) and no greater than 20 weeks (140 days) prior to randomization.
  8. Must have an ECOG performance status score of less than or equal to 2.
  9. Females of childbearing potential (FCBP)† must:

    • Have two negative medically supervised pregnancy tests prior to starting of study therapy. She must agree to ongoing pregnancy testing during the course of the study, and after end of study therapy. This applies even if the subject practices complete and continued sexual abstinence.
    • Either commit to continued abstinence from heterosexual contact (which must be reviewed on a monthly basis) or agree to use, and be able to comply with, effective contraception without interruption, 28 days prior to starting study drug, during the study therapy (including dose interruptions), and for 28 days after discontinuation of study therapy.
  10. Male subjects must:

    • Commit to continued abstinence from heterosexual contact or agree to use a condom during sexual contact with a FCBP, even if they have had a vasectomy, throughout study drug therapy, during any dose interruption and after cessation of study therapy.
