   2. Aspartate amino transferase (AST) or alanine amino transferase (ALT) <= 3.0 x ULN
   3. Alkaline phosphatase (ALP) <= 3.0 x ULN
   4. Total Bilirubin level of < 1.5 mg/dL x the institutional ULN unless secondary to Gilbert's disease (or pattern consistent with Gilbert's)
6. Hepatitis B sAg negative and HepB cAb negative. Note: Patients who are HepB sAg negative but are HepB cAb positive (regardless of HepB sAb status) will NOT be allowed.

2. Treatment for CLL within last 4 weeks. (Patients who have received steroids or IVIG for autoimmune complications of CLL are eligible).
3. Current active hepatic or biliary disease (with the exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases, or stable chronic liver disease, per assessment by the treating physician).

5. Central nervous system lymphoma/CLL.
6. Transformation of CLL to aggressive non-Hodgkin lymphoma (NHL) (i.e., Richter's transformation).
7. History of other malignancy <= 2 years of study entry which could affect compliance with the protocol or interpretation of results. History of curatively treated basal or squamous cell carcinoma of the skin or in situ carcinoma of the cervix, low grade, early-stage, localized prostate cancer treated surgically with curative intent, ductal carcinoma in situ (DCIS) of the breast treated with curative intent, are generally eligible.
