This study is evaluating the efficacy of obinutuzumab in combination with chlorambucil compared with ACP-196 in combination with obinutuzumab (Arm B) for the treatment of previously untreated chronic lymphocytic leukemia (CLL).

Inclusion Criteria:
Men and women: ≥ 65 years of age OR > 18 and < 65 years of age, provided that they meet at least one of the following criteria: Creatinine clearance 30 to 69 mL/min; A score higher than 6 on the Cumulative Illness Rating Scale-Geriatric; ECOG performance status of 0, 1, or 2; Diagnosis of CLL; Active disease meeting ≥ 1 of the following IWCLL 2008 criteria for requiring treatment; Measurable nodal disease by CT; Meet the following laboratory parameters: a. ANC ≥ 750 cells/μL, or ≥ 500 cells/μL in subjects with documented bone marrow involvement, and independent of growth factor support 7 days before assessment; b.Platelet count ≥ 50,000 cells/μL, or ≥ 30,000 cells/μL in subjects with documented bone marrow involvement, and without transfusion support 7 days before assessment. Subjects with transfusion-dependent thrombocytopenia are excluded; c.Serum AST and ALT/SGPT < 3.0 x ULN; d.Total bilirubin ≤ 2.5 x ULN; e.Estimated creatinine clearance ≥ 30 mL/min.
