- 1. Males or females of 65 years of age or greater. Patients between the ages of 65 and 70 years of age must have 1 or more of the following comorbidities that may preclude the use of frontline chemo-immunotherapy with fludarabine, cyclophosphamide, or rituximab: - creatinine clearance < 70 mL/min using the Cockcroft-Gault equation - platelet count < 100,000/μL or hemoglobin < 10 g/dL - clinically apparent autoimmune cytopenia (autoimmune hemolytic anemia or immune thrombocytopenia) - ECOG performance score = 1 or 2 2. Diagnosis of CLL/SLL that meets IWCLL diagnostic criteria (Hallek 2008) 3. Active disease meeting at least 1 of the following IWCLL criteria (Hallek 2008) for requiring treatment: - Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia and/or thrombocytopenia Massive, progressive, or symptomatic splenomegaly - Massive nodes or progressive or symptomatic lymphadenopathy - Progressive lymphocytosis - Autoimmune hemolytic anemia and/or immune thrombocytopenia that is poorly responsive to corticosteroids or standard therapy - Constitutional symptoms 4. Measurable nodal disease by computed tomography (CT) 5. ECOG performance status of 0-2 6. Life expectancy > 4 months from randomization 7. Adequate hematologic function, defined as absolute neutrophil count (ANC) ≥ 1,000/μL (independent of growth factor support for at least 7 days prior to screening) and platelet count ≥ 50,000/μL (independent of transfusion and growth factor support for at least 7 days prior to screening) 8. Adequate hepatic function, defined as serum aspartate transaminase (AST) and alanine transaminase (ALT) < 2.5 x upper limit of normal (ULN), and total bilirubin ≤ 1.5 x ULN 9. Adequate renal function, defined as estimated creatinine clearance ≥ 30 mL/min using the Cockcroft-Gault equation 10. Willingness to receive all outpatient treatment, all laboratory monitoring, and all radiological evaluations at the institution that administers study drug for the entire study 11. Willingness of male patients, if sexually active with a female of childbearing potential, to use an effective barrier method of contraception during the study and for 3 months following the last dose of study drug 12. Ability to provide written informed consent and to understand and comply with the requirements of the study
- 1. Known involvement of the central nervous system by lymphoma or leukemia 2. History or current evidence of Richter's transformation or prolymphocytic leukemia 3. Documentation of deletion of the short arm of chromosome 17: del(17p13.1) in more than 20% of cells examined on any pretreatment fluorescence in situ hybridization (FISH) or cytogenetic evaluation 4. Uncontrolled autoimmune hemolytic anemia or idiopathic thrombocytopenic purpura 5. Any previous treatment (chemotherapy, radiotherapy, and/or monoclonal antibodies) intended specifically to treat CLL/SLL 6. Received any immunotherapy, vaccine, or investigational drug within 4 weeks prior to randomization 7. Corticosteroid use within 1 week prior to first dose of study drug, with the exception of inhaled, topical, or other local administrations. Patients requiring systemic steroids at daily doses > 20 mg prednisone (or corticosteroid equivalent, see Appendix N), or those who are administered steroids for leukemia control or white blood cell (WBC)-count-lowering are excluded. 8. Major surgery within 4 weeks prior to randomization 9. History of prior malignancy, with the exception of the following: - malignancy treated with curative intent and with no evidence of active disease present for more than 3 years prior to screening and felt to be at low risk for recurrence by treating physician - adequately treated nonmelanomatous skin cancer or lentigo maligna melanoma without current evidence of disease - adequately treated cervical carcinoma in situ without current evidence of disease 10. Currently active, clinically significant cardiovascular disease or a history of myocardial infarction within 6 months prior to randomization 11. Inability to swallow capsules or tablets, or disease significantly affecting gastrointestinal function 12. Uncontrolled active systemic fungal, bacterial, viral, or other infection or requirement for intravenous (IV) antibiotics 13. Known history of infection with human immunodeficiency virus (HIV) 14. Serologic status reflecting active hepatitis B or C infection 15. History of stroke or intracranial hemorrhage within 6 months prior to enrollment 16. Current life-threatening illness, medical condition, or organ-system dysfunction that could compromise patient safety or put the study at risk 17. Requirement for anticoagulation with warfarin 18. Requirement for treatment with a strong CYP3A4/5 and/or CYP2D6 inhibitor
