Exclusion Criteria:

1. Any previous treatment for B-CLL or any other treatments that can be considered active against B-CLL
2. Glucocorticoid unless given in doses ≤ 10 mg /day for other indications than B-CLL (e.g. asthma)
3. Known transformation of B-CLL
4. Known CNS involvement of B-CLL
5. Past or current malignancy, except for:

   1. Cervical carcinoma Stage 1B or less
   2. Non-invasive basal cell and squamous cell skin carcinoma
   3. Malignant melanoma with a complete response of a duration of \> 10 years
   4. Other cancer diagnoses with a complete response of a duration of \> 5 years
6. Chronic or current infectious disease requiring systemic treatment
7. Clinically significant cardiac disease
8. Significant concurrent, uncontrolled medical condition
9. History of significant cerebrovascular disease
10. Known HIV positive
11. Positive serology for hepatitis B, unless due to vaccination
