Details and patient eligibility

About

The aim of the current trial is to evaluate if combination treatment with venetoclax + ibrutinib in patients with relapsed or refractory chronic lymphocytic leukemia (RR CLL) can lead to MRD negativity, which may induce long lasting remissions for MRD-negative patients randomized to stopping treatment after 15 induction cycles.

Inclusion criteria

  • Documented CLL or SLL requiring treatment according to IWCLL criteria after either being refractory to first line therapy or relapse after initial therapy.

    • Age at least 18 years.

    • Adequate bone marrow function defined as:

      • Absolute neutrophil count (ANC) >0.75 x 109/L
      • Platelet count >30,000 /μL 30 x 109/L.
      • Hemoglobin >8.0 g/dL (5 mmol/L) Unless directly attributable to CLL infiltration of the bone marrow, proven by bone marrow biopsy
    • Creatinine clearance (CrCL) ≥ 30ml/min calculated according to the modified formula of Cockcroft and Gault or directly measured with 24hr urine collection.

    • Adequate liver function as indicated

      • Serum aspartate transaminase (AST) or alanine transaminase (ALT) ≤ 3.0 x upper limit of normal (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 PTT (activated partial thromboplastin time [aPTT]) <1.5 x ULN (unless abnormalities are related to coagulopathy or bleeding disorder).
    • 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 dose), negative testing for hepatitis C RNA within 42 days prior to registration.

    • WHO/ECOG performance status 0-3 (appendix C), stage 3 only if attributable to CLL.

    • Negative pregnancy test at study entry (for women of childbearing potential).

    • Male and female subjects of reproductive potential must agree to use both a highly effective method of birth control (e.g. implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], complete abstinence , or sterilized partner) and a barrier method (e.g., condoms, cervical ring, sponge, etc.) during the period of therapy and for 90 days after the last dose of study drug.

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

    • Written informed consent.

Exclusion criteria

  • Any prior therapy with ibrutinib and/or venetoclax.
  • Transformation of CLL (Richter's transformation).
  • Patients with a history of confirmed progressive multifocal leukoencephalopathy (PML).
  • Malignancies other than CLL currently requiring systemic therapies or not being treated in curative intention before or showing signs of progression after curative treatment.
  • Known allergy to xanthine oxidase inhibitors and/or rasburicase.
  • Known bleeding disorders (e.g., von Willebrand's disease or hemophilia).
  • Uncontrolled or active infection.
  • Patients requiring treatment with a strong cytochrome P450 (CYP) 3A inhibitor (see appendix K). or anticoagulant therapy with warfarin or phenoprocoumon or other vitamin K antagonists. Please note: Patients being treated with NOACs can be included, but must be properly informed about the potential risk of bleeding under treatment with ibrutinib.
  • History of stroke or intracranial hemorrhage within 6 months prior to registration.
  • Major surgery within 28 days prior to registration.
  • Use of investigational agents which might interfere with the study drug within 28 days prior to registration.
  • Vaccination with live vaccines within 28 days prior to registration
  • Steroid therapy within 7 days prior to registration, with the exception of inhaled steroids for asthma, topical steroids, steroids up to 25 mg of prednisolone daily to control autoimmune phenomenon's, or replacement/stress corticosteroids.
  • Pregnant women and nursing mothers.
  • Any psychological, familial, sociological and geographical condition potentially hampering compliance with the study protocol and follow-up schedule.

230 participants in 3 patient groups

Ibrutinib until progression/relapse
Experimental group
Description:
All patients receive ibrutinib + venetoclax (with delayed start and ramp up of venetoclax from cycle 3) for the 15 cycles. MRDpositive patients (PB and BM) will continue on Ibrutinib maintenance (non-randomized group) until progression/relapse
Treatment:
Drug: Ibrutinib until progression/relapse
Drug: Ibrutinib + Venetoclax 15 cycles
Arm A
Experimental group
Description:
All patients receive ibrutinib + venetoclax (with delayed start and ramp up of venetoclax from cycle 3) for the 15 cycles. MRD negative patients (PB and BM) will be randomized to Arm A or Arm B. Arm A: Ibrutinib until progression/relapse (Continuous ibrutinib treatment until toxicity or progression)
Treatment:
Drug: Ibrutinib until progression/relapse
Drug: Ibrutinib + Venetoclax 15 cycles
Arm B
Experimental group
Description:
All patients receive ibrutinib + venetoclax (with delayed start and ramp up of venetoclax from cycle 3) for the 15 cycles. MRD negative patients (PB and BM) will be randomized to Arm A or Arm B. Arm B: Observation until event. Patients randomized to Arm B will get reinitiation of therapy during the observation period in case of: * progression according to IWCLL criteria or * MRD≥10-3 (PB) and at least one month later MRD ≥10-2 (PB). Treatment reinitiation will consist of ibrutinib and venetoclax (with ramp up of venetoclax from cycle 1) for 12 cycles
Treatment:
Drug: Possible reinitiation treatment: Ibrutinib + Venetoclax 12 cycles
Drug: Ibrutinib + Venetoclax 15 cycles
