  • Outcome Measures

    Primary Outcome Measures

    1. Investigator-assessed progression-free survival (PFS) [Up to 80 month]

      Time from randomization to the first occurrence of progression or relapse (determined using standard iwCLL guidelines), or death from any cause, whichever occurs first

    Secondary Outcome Measures

    1. Rates of undetectable minimal residual disease (uMRD) in peripheral blood (PB) and bone marrow (BM) [At final restaging (RE): 18 months after start of treatment and additional BM assessment approx. 12 months after RE]

      Undetectable MRD (uMRD) is defined as <10-4 (=1 CLL-cell per 10,000 leukocytes analyzed).The uMRD rate is defined as the proportion of patients having achieved uMRD.

    2. MRD levels in PB at different time points [Up to 80 month]

      MRD is defined as the number of CLL-cells that can be detected in peripheral blood (PB) or bone marrow (BM). MRD values will be categorized into negative (<10-4) and positive (≥10-4)

    3. Overall response rate (ORR) [At final restaging (RE): 18 months after start of treatment]

      Proportion of patients having achieved a complete response (CR), a CR with incomplete recovery of the bone marrow (CRi), or a partial response (PR) as best response.

    4. CR/CRi rate [At final restaging (RE): 18 months after start of treatment]

      Proportion of patients having achieved a CR or CRi as best response (= number of patients with best response CR or CRi divided by the number of the intention-to-treat population (ITT) population)

    5. Incidence of safety parameters such as adverse events (AE) and adverse events of particular/special interest (AEPI/AESI) [Up to 80 month]

      Type, frequency, severity and relationship to study treatment.of AEs and AEPIs/AESIs

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    1. Documented CLL requiring treatment according to iwCLL criteria.

    2. Age at least 18 years.

    3. Life expectancy ≥ 6 months.

    4. Ability and willingness to provide written informed consent and to adhere to the study visit schedule and other protocol requirements.

    5. Adequate bone marrow function independent of growth factor or transfusion support within 2 weeks of screening initiation as follows, unless cytopenia is due to CLL:

    6. Absolute neutrophil count ≥ 1.0 × 109/L

    7. Platelet counts ≥ 30 × 109/L; in cases of thrombocytopenia clearly due to CLL (per the discretion of the investigator), platelet count should be ≥ 10 × 109/L

    8. Total haemoglobin ≥ 9 g/dL (without transfusion support, unless anaemia is due to CLL)

    9. GFR >30ml/min directly measured with 24hr urine collection, calculated according to the modified formula of Cockcroft and Gault (for men: GFR ≈ ((140 - age) x bodyweight)/ (72 x creatinine), for women x 0, 85) or an equally accurate method.

    1. For patients with creatinine values within the normal range the calculation of the clearance is not necessary. Dehydrated patients with an estimated creatinine clearance less than 30 ml/min may be eligible if a repeat estimate after adequate hydration is > 30 ml/min.
    1. Adequate liver function as indicated by a total bilirubin ≤ 2 x, AST/ ALT ≤ 2.5 x the institutional ULN value, unless directly attributable to the patient's CLL or to Gilbert's Syndrome.

    2. Negative serological testing for hepatitis B (HbsAg negative and anti-HBc negative; patients positive for anti-HBc may be included if PCR for HBV DNA is negative and HBV-DNA PCR is performed every month until 12 months after last treatment cycle), negative testing for hepatitis C RNA within 6 weeks prior to registration for study screening (i.e. PCR only required when serology was positive).

    3. Eastern Cooperative Oncology Group Performance Status (ECOG) performance status 0-2.

    Exclusion criteria:
    1. Any prior CLL-specific therapies (except corticosteroid treatment administered due to necessary immediate intervention; within the last 10 days before start of study treatment, only dose equivalents up to 20 mg prednisolone are permitted).

    3. Patients with a history of PML.

    4. An individual organ/ system impairment score of 4 as assessed by the CIRS definition limiting the ability to receive the study treatment or any other life-threatening illness, medical condition or organ system dysfunction that, in the investigator´s opinion, could compromise the patients' safety or interfere with the absorption or metabolism of the study drugs (e.g. inability to swallow tablets or impaired resorption in the gastrointestinal tract).

    5. Malignancies other than CLL currently requiring systemic therapies, not being treated with curative intent before (unless the malignant disease is in a stable remission due to the discretion of the treating physician or showing signs of progression after curative treatment.

    9. Anticoagulant therapy with warfarin or phenprocoumon, (alternative anticoagulation is allowed (e.g. DOACs), but patients must be properly informed about the potential risk of bleeding under treatment with ibrutinib).

    19. Fertile men or women of childbearing potential unless:

    20. surgically sterile or ≥ 2 years after the onset of menopause

    21. willing to use two methods of reliable contraception including one highly effective contraceptive method (Pearl Index <1) and one additional effective (barrier) method during study treatment and for 18 months after the end of study treatment.
