入选标准
- •Men and women ≥ 18 years of age.

- •Willing and able to participate in all required evaluations and procedures in this study protocol, including swallowing capsules without difficulty.
- •Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (in accordance with national and local patient privacy regulations).
- •ECOG performance status of 0 to
- •Diagnosis of CLL that meets published diagnostic criteria (Hallek 2008): a. Monoclonal B-cells (either kappa or lambda light chain restricted) that are clonally co-expressing ≥ 1 B-cell marker (CD19, CD20, or CD23) and CD
- •b. Prolymphocytes may comprise ≤ 55% of blood lymphocytes. c. Presence of ≥ 5 x 109 B lymphocytes/L (5000/µL) in the peripheral blood (at any point since initial diagnosis).
- •Must have documented CD20-positive CLL.
- •Active disease meeting ≥ 1 of the following IWCLL 2008 criteria for requiring treatment: a. Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia (hemoglobin < 10 g/dL) and/or thrombocytopenia (platelets < 100,000/μL). b. Massive (i.e., ≥ 6 cm below the left costal margin), progressive, or symptomatic splenomegaly. c. Massive nodes (i.e., ≥ 10 cm in the longest diameter), progressive, or symptomatic lymphadenopathy. d. Progressive lymphocytosis with an increase of > 50% over a 2-month period or a LDT of < 6 months. LDT may be obtained by linear regression extrapolation of ALC obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In subjects with initial blood lymphocyte counts of < 30 x 109/L (30,000/μL), LDT should not be used as a single parameter to define indication for treatment. In addition, factors contributing to lymphocytosis or lymphadenopathy other than CLL (e.g., infections) should be excluded. e.

Platelet count ≥ 50,000 cells/μL (50 x 109 /L), or ≥ 30,000 cells/μL (30 x 109/L) in subjects with documented bone marrow involvement, and without transfusion support 7 days before assessment. Subjects with transfusion-dependent thrombocytopenia are excluded. If an Investigator has chosen bendamustine/rituximab as the Arm B treatment, platelets must be ≥ 75,000 cells/μL (75 x 109/L). c. Serum AST and ALT ≤ 2.0 x ULN. d. Total bilirubin ≤ 1.5 x ULN. e.

Highly effective forms of contraception are defined in Section 9.2.
