- Adequate bone marrow, kidney, and liver function as defined by: WBC ≥ 2000/μL. Neutrophils ≥ 1500/μL. Platelets ≥ 100 x103/μL. Hemoglobin > 9.0 g/dL. Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min (if using the Cockcroft-Gault formula): Female CrCl = (140 - age in years) x (weight in kg x 0.85)/(72 x serum creatinine in mg/dL). Male CrCl = (140 - age in years) x (weight in kg x 1.00)/(72 x serum creatinine in mg/dL). AST/ALT ≤ 3 x ULN. Total Bilirubin ≤ 1.5 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL).
