   - ECOG performance status of 0 to 2.

   - Diagnosis of CLL.

   - Must have ≥ 1 of the following high-risk prognostic factors:

      - Presence of 17p del by central laboratory.

      - Presence of 11q del by central laboratory.

   - Active disease meeting ≥ 1 of the following IWCLL 2008 criteria for requiring
   treatment

   - Must have received ≥ 1 prior therapies for CLL.

      assessment. Participants with transfusion-dependent thrombocytopenia are
      excluded.

      - Total bilirubin ≤ 1.5 x ULN.

      - Estimated creatinine clearance ≥ 30 mL/min.

Exclusion Criteria:

   - Known CNS lymphoma or leukemia.

   - Known prolymphocytic leukemia or history of, or currently suspected, Richter's
   syndrome.

   - Uncontrolled autoimmune hemolytic anemia or idiopathic thrombocytopenia purpura.

   - Prior exposure to ibrutinib or to a B-cell receptor (BCR) inhibitor or a B-cell
   lymphoma-2 (BCL-2) inhibitor.

   - Received any chemotherapy, external beam radiation therapy, anticancer antibodies, or
   investigational drug within 30 days before first dose of study drug.

   - Prior radio- or toxin-conjugated antibody therapy.

   - Prior allogeneic stem cell or autologous transplant.

   - Major surgery within 4 weeks before first dose of study drug.

   - Prior malignancy, except for adequately treated lentigo maligna melanoma,
   non-melanomatous skin cancer, in situ cervical carcinoma or other malignancy treated
   with no evidence of active disease > 3 years before Screening and at low risk for
   recurrence.

   - Significant cardiovascular disease within 6 months of screening.

   - Known history of infection with human immunodeficiency virus (HIV).

   - History of stroke or intracranial hemorrhage within 6 months before randomization.

   - History of bleeding diathesis.

   - Requires or receiving anticoagulation with warfarin or equivalent vitamin K
   antagonists within 7 days of first dose of study drug.

   - Requires treatment with a strong cytochrome P450 3A (CYP3A) inhibitor/inducer.
