• Documented CLL or SLL requiring treatment according to IWCLL criteria, including minimal required markers (CD5/CD19/CD23 triple positive with light chain restriction);
• WHO performance status 0-3 stage 3 only if attributable to CLL/SLL;
• No prior treatment for CLL/SLL;
• Age at least 18 years;
• Adequate BM function defined as:
- Hb > 5 mmol/l or Hb > 8 g/dL
- Absolute neutrophil count (ANC) = 0.75 x 109/L or 750/µL
- Platelet count = 50 x 109/L or 50,000 /µL
Unless directly attributable to CLL/SLL infiltration of the BM, proven by BM biopsy;
• Estimated Glomerular Filtration Rate (eGFR) (MDRD) or estimated creatinine clearance (CrCl) = 30 l/min (Cockcroft-Gault );
Please note: in case eGFR or CrCl is <50ml/min the patient needs to be considered high risk for TLS
• Adequate liver function as indicated:
- Serum aspartate transaminase (ASAT) and alanine transaminase (ALAT) = 3.0 x ULN
- Bilirubin =1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of nonhepatic origin);
• Prothrombin time (PT)/International normal ratio (INR) <1.5 x ULN and activated partial thromboplastin time (aPTT) <1.5 x ULN;
• Negative serological testing for hepatitis B virus (Hepatitis B surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc) negative) and hepatitis C virus (hepatitis C antibody). Subjects who are positive for hepatitis B core antibody, hepatitis B surface antigen, or hepatitis C antibody must have a negative PCR result before enrollment. Those who are PCR positive will be excluded;
• Ability and willingness to adhere to the study visit schedule and other protocol requirements;
• Patient is capable of giving informed consent;
• Written informed consent.
