E.3 | Principal inclusion criteria |
1. Signed written informed consent. 2. 18 years of age or older. 3. Medically fit patients without relevant comorbidity, defined as total CIRS score ≤ 6. 4. WHO performance status of 0-2. 5. Confirmed diagnosis of CLL in need of treatment (Binet C or A/B with active disease) according to the updated IWCLL guidelines (Hallek et al. 2008). 6. Life expectancy > 12 weeks. 7. Relapsed or refractory disease after at least one, but no more than 3 prior regimens. Patients who previously received bendamustine (with or without rituximab) must have had at least a partial response with duration of response of at least six months. 8. Anti-cancer therapy, major surgery, or irradiation was completed > 3 weeks before registration in this study. Patients must have recovered from the acute side effects incurred as a result of previous therapy. 9. Patient is able and willing to receive adequate anticoagulation as specified in this protocol. 10. Adequate liver function as indicated by a total bilirubin, AST, and ALT ≤2 the institutional ULN value, unless directly attributable to the patient’s tumor. 11. Creatinine clearance >60ml/min calculated according to the modified formula of Cockcroft and Gault or directly measured after 24h-urine collection. 12. ANC > 1500/µl and platelet count > 75.000/μl, unless decrease is due to bone marrow involvement of CLL 13. Negative serological hepatitis B test, negative testing of hepatitis C RNA, negative HIV test within 6 weeks prior to registration. 14. Females of childbearing potential (FOCP) must understand that the study medication has a teratogenic risk and must agree to use, and be able to comply with effective contraception without interruption, 4 weeks before starting study drug, throughout study drug therapy (including dose interruptions) and for 6 months after the end of study drug therapy, even if she has amenorrhea. This applies unless the subject commits to absolute and continued abstinence confirmed on a monthly basis.
The following are effective methods of contraception - Implant - Levonorgestrel-releasing intrauterine system (IUS) - Medroxyprogesterone acetate depot - Tubal sterilization - Sexual intercourse with a vasectomised male partner only; vasectomy must be confirmed by two negative semen analyses - Ovulation inhibitory progesterone-only pills (i.e., desogestrel) in combination with another contraceptive method FOCP must • agree to have a medically supervised pregnancy test with a minimum sensitivity of 25 mIU/ml on the day of the study visit or in the 3 days prior to the study visit once the subject has been on effective contraception for at least 4 weeks. This requirement also applies to women of childbearing potential who practice complete and continued abstinence. The test should ensure the subject is not pregnant when she starts treatment. • agree to have a medically supervised pregnancy test every 4 weeks including 4 weeks after the end of study treatment, except in the case of conformed tubal sterilization. These pregnancy test should be performed on the day of the study visit or in the 3 days prior to the study visit. This requirement also applies to women of childbearing potential who practice complete and continued abstinence. Male subjects must • agree to use condoms throughout study drug therapy, during any dose interruption and for one week after cessation of study drug therapy if their partner is of childbearing potential and has no contraception • agree not to donate semen during study drug therapy and for one week after end of study drug therapy All subjects must • agree to abstain from donating blood while taking study drug therapy and for one week following discontinuation of study drug therapy • agree not to share study drug with another person and to return all unused study drug to the investigator or pharmacist

History of anaphylaxis following exposure to any of the used study-drugs and/or thalidomide. 5. Evidence of TLS per the Cairo-Bishop definition of laboratory TLS (subjects may be enrolled upon correction of electrolyte abnormalities). 6. Participation in another clinical trial and/or use of investigational agents or concurrent anti cancer treatment within the last 4 weeks of registration. 7. Other severe, concurrent diseases, including tuberculosis, mental disorders, serious cardiac functional capacity (class III or IV as defined by the New York Heart Association Classification), severe diabetes, severe hypertension, pulmonary disease (COPD with hypoxemia), or major organ malfunction that could interfere with the patient’s ability to participate in the study. 8. Pregnant or lactating women. 9. Any circumstance at the time of study entry that would preclude completion of the study or the required follow-up. 10. Active secondary malignancy requiring treatment (except basal cell carcinoma or malignant tumor curatively treated by surgery) within the last 5 years before registration. 11.
