Brief Summary:
This is an open-labeled, single arm, Phase II, two staged study of combination of ibrutinib and rituximab in patients with autoimmune cytopenia and underlying CLL. In stage I (remission induction) patients will receive ibrutinib and rituximab for 6 months; in stage II (maintenance) - only ibrutinib until relapse, progression or unacceptable toxicity. A total of 50 patients will be enrolled into the trial. The results will be compared to historical control, efficacy of rituximab as monotherapy or in combination with chemotherapy in patients with AIC and underlying CLL.

Condition or disease Intervention/treatment Phase
AIHA - Warm Autoimmune Hemolytic Anemia Drug: Ibrutinib Phase 2

Detailed Description:

Subjects will give informed consent before any protocol specific assessments. Blood samples, physical examination, CT scan and bone marrow examination will be performed to determine baseline disease status and study eligibility. All examinations must be performed ≤ 14 days prior to first infusion, with the exception of the CT scan and bone marrow examination. The CT scan and the bone marrow examination will be performed within 6 weeks of first infusion.

treatment regimen: Rituximab 375 mg/m2 8 weekly infusions (days 1, 8, 15, 22, 29, 36, 43, 50, 57), then 3 infusion every 28 days (days 85, 113, 141) Ibrutinib 420 mg (3 tablets) daily, constantly for 6 months

Disease status assessments to determine subject response or progression will be performed monthly according to NCI Criteria and will include:

  • Physical examination including lymph node examination, spleen and liver measurement, and detection of constitutional symptoms
  • Peripheral blood sample evaluation of complete blood count (CBC) and differential (expressed in % and absolutes)
  • Direct antiglobulin test
  • In addition, subjects will be monitored for safety, efficacy.

After completion of the induction phase, subjects achieving CR or PR (for AIC and CLL) will continue maintenance phase. During maintenance phase patients will receive:

ibrutinib 420 mg (3 tablets) daily, constantly until progression or unacceptable toxicity Survival and disease status assessments will be performed 1 month post treatment and every 2 months until total observation time.

In addition, subjects will be monitored for safety and efficacy.

  • Bone marrow examination is required for confirmation of CR 1 months post final rituximab infusion. Minimal Residual Disease (MRD) assessment of the bone marrow aspirate will also be performed for subjects demonstrating a CR.
  • In PRCA patients with clinical evidence of response for anemia the bone marrow examination is required independently of CLL status at 1 month post last rituximab infusion.
  • All subjects with clinical CR will receive MRD assessment of the peripheral blood during maintenance phase. In subjects achieved MRD-negative result in blood in two consecutive measurements bone marrow examination is required for confirmation of CR.
  • CT-Scans will be performed for patients achieving a CR, PR or SD at 1 month post last rituximab infusion. CT-Scans must be repeated every 12 months beginning since final assessment of response after induction phase.

Follow-up assessment for subjects experiencing CLL progression or relapse of AIC during the maintenance phase requires a 1 month post-treatment safety assessment. Subsequent follow up visits include assessment of survival status, date of next CLL therapy, type of therapy and response to therapy.

Primary Outcome Measures :
  1. Response rate [ Time Frame: 3 month after treatment ]
    Response rate defined by transfusion independence, hemoglobin level, DAT and duration of response of autoimmunity (DR-AI), defined as the interval between time point of best response and relapse of AIC. Relapses of CLL will be censored.
