• Resolved acute effects of any prior therapy to baseline or Grade ≤1 severity

• Screening laboratory:

  1. Hematologic: ANC ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L, and hemoglobin ≥ 9 g/dL
  2. Hepatic: Total bilirubin level ≤ 1.5 × the ULN range and AST and ALT levels ≤ 2.5 × ULN or AST and ALT levels ≤ 5 X ULN (for subjects with documented metastatic disease to the liver)
  3. Renal: Estimated creatinine clearance ≥ 30 mL/min according to the Cockcroft-Gault formula or serum creatinine ≤ 2.0 mg/dL.
  4. Albumin ≥2.5 g/dL.
  5. Coagulation: PT time and INR within normal limits (+/-15%). PTT within normal limits (+/-15%).
• If a subject requires anticoagulation, treatment must be modified to enoxaparin.
• Negative serum pregnancy test if female subject is of childbearing potential.
• Patients who are willing and able to comply with scheduled visits, treatment plans, laboratory tests, biopsies when required, and other procedures.
