fludarabine/cyclophosphamide/rituximab, or bendamustine/rituximab or
fludarabine/rituximab or fludarabine/cyclophosphamide,(in case of

6. Must have achieved a response of at least PR (IWCLL guidelines for the
diagnosis and treatment of chronic lymphocytic leukemia [Hallek, 2008])
following completion (minimum 4 cycles) of first-line induction therapy prior
to randomization (documentation of response status must be available).
and have either:
a. MRD levels in the peripheral blood at final restaging of >=10^2 or

least one of the following factors:
• an unmutated IGHV-status
• 17p-deletion or

7. Must have completed last cycle of at least 4 cycles of first-line induction
no less than 8 weeks (56 days) and no greater than 20 weeks (140 days)
prior to randomization.
8. Subjects who completed first line induction treatment with less than 6

9. Must have an Eastern Cooperative Oncology Group (ECOG)
performance status score of <=2.
10. Negative serological Hepatitis B test, negative testing of Hepatitis C

11. Females of childbearing potential (FCBP)*
• 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.
must:
• Either commit to continued abstinence from heterosexual
intercourse (which must be reviewed on a monthly basis) or agree to
use, and be able to comply with, two reliable forms of effective

Definition: This protocol defines a female of childbearing potential as a sexually mature woman who: 1) has not undergone a hysterectomy or
bilateral oophorectomy or 2) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing
potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

discontinuation of study therapy.

8. Known presence of alcohol and/or drug abuse.
9. Central nervous system (CNS) involvement as documented by spinal fluid cytology or imaging. Subjects who have signs or symptoms suggestive of leukemic meningitis or a history of leukemic meningitis must have a lumbar puncture procedure performed within two weeks prior to randomization.
10. Prior history of malignancies, other than CLL, unless the subject has been free of the disease for >=5 years. Exceptions include the folowing:
