- Serum creatinine within upper limits of normal or calculated clearance ≥50 mL/min/1.73 m2. If using creatinine clearance, actual body weight should be used for calculating creatinine clearance (eg, using the Cockroft-Gault formula). For subjects with a Body Mass Index (BMI) >30 kg/m2, lean body weight should be used instead 8. Cancer antigen (CA)19-9 <100 U/mL assessed within 14 days of randomization 9. Acceptable coagulation studies as demonstrated by Prothrombin Time (PT) and Partial Thromboplastin Time (PTT) within normal limits (±15%)
