Inclusion Criteria
  • Must have relapsed or refractory Chronic Lymphocytic Leukemia (CLL), received no more than 5 prior myelosuppressive/chemotherapy regimens and must be a candidate for treatment with either Fludarabine/Cyclophosphamide/Rituximab (FCR) or Bendamustine/Rituximab (BR);
  • Subject has an Eastern Cooperative Oncology Group (ECOG) performance score of </=1;
  • Must have adequate bone marrow independent of growth factor support (with the exception of subjects with bone marrow heavily infiltrated with underlying disease [80% or more] who may use growth factor support to achieve Absolute Neutrophil Count (ANC) eligibility criteria), per local laboratory reference range at Screening as follows: ANC >/=1000/mcL, Platelets>/= 100,000/mm3 (entry platelet count must be independent of transfusion within 14 days of Screening),Hemoglobin >/= 9.0 g/dL.
Exclusion Criteria
  • Subject has history or is clinically suspicious for cancer-related Central Nervous System disease;
  • Has history of severe allergic or anaphylactic reactions to human, humanized, chimeric or murine monoclonal antibodies;
  • Has undergone an allogeneic stem cell transplant; Exhibits evidence of other uncontrolled condition(s) including, but not limited to: uncontrolled systemic infection, diagnosis of fever and neutropenia within 1 week prior to study drug administration;
  • Has underlying, predisposing condition of bleeding or currently exhibits signs of bleeding; Has a recent history of non-chemotherapy induced thrombocytopenic associated bleeding;
  • Currently receiving or requires anticoagulation therapy;
  • Has active immune thrombocytopenic purpura (ITP) or a history of being refractory to platelet transfusions (within 1 year prior to 1st dose of study drug);
  • Has active peptic ulcer disease or other hemorrhagic esophagitis/gastritis.

Primary Outcome Measures
NameTimeMethod
Assess the safety profile, characterize pharmacokinetics, and determine the MTD and recommended Phase 2 dose (RPTD) of ABT-263 when administered in combination with either FCR or BR in subjects with relapsed or refractory CLL.Safety assessments = 1 wk, Pharmacokinetic (PK) Sampling = 1 wk for 1st 2 cycles, then, every other cycle starting Cycle 3 to Cycle 9, Determination of MTD & RPTD = Every 60 days
Secondary Outcome Measures
NameTimeMethod
Evaluate preliminary data regarding progression-free survival (PFS), tumor response rate and overall survival (OS) when ABT-263 is administered in combination with either FCR or BR.Every 2 months
