1. Platelet count < 50,000 cells/mm3

2. Absolute neutrophil count < 1,000 cells/mm3

3. Hemoglobin < 8.0 g/dL (hemoglobin may be maintained by erythropoietin or transfusion)

4. AST and/or ALT > 2.5 X the upper limit of normal

5. Total bilirubin > 1.5 X the upper limit of normal

6. Serum creatinine > 2 mg/dL

• Subject has a known history of human immunodeficiency virus (HIV), hepatitis B, and/or hepatitis C infection.

• Subject has a clinically relevant active infection and/or a serious co-morbid medical condition such as recent myocardial infarction, unstable angina, difficult-to-control congestive heart failure, uncontrolled hypertension, difficult-to-control cardiac arrhythmias, chronic obstructive or chronic restrictive pulmonary disease, and/or cirrhosis.
