A Study of Ibrutinib in Combination With Bendamustine and Rituximab in Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma


About this study

The purpose of this study is to examine the safety and efficacy of Ibrutinib administered in combination with bendamustine and rituximab in patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.

  • Relapsed or refractory CLL or SLL following at least 1 prior line of systemic therapy consisting of at least 2 cycles of a chemotherapy-containing regimen
  • Eastern Cooperative Oncology Group Performance Status score of 0 or 1

  • The presence of deletion of the short arm of chromosome 17
  • Patients previously treated with a bendamustine-containing regimen who did not achieve a response or who relapsed and required treatment within 24 months of treatment with that regimen

  • Received a hematopoietic stem cell transplant
  • Known central nervous system leukemia/lymphoma or Richter's transformation
  • Patients with uncontrolled autoimmune hemolytic anemia or autoimmune thrombocytopenia
  • Chronic use of corticosteroids

  • Known history of human immunodeficiency virus or hepatitis C, or active infection with hepatitis B or C
  • Any uncontrolled active systemic infection or any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the patient's safety, interfere with the absorption or metabolism of ibrutinib capsules, or put the study outcomes at undue risk
