- Has adequate organ function at screening: 7.1 Total bilirubin ≤1.5 × upper limit of normal (ULN) (<3 × ULN if participant has history of Gilbert’s Syndrome). 7.2 Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤3 × ULN. 7.3 Creatinine clearance (CrCl) ≥45 mL/min (calculated by the Cockcroft-Gault Equation, see Appendix 9 of the protocol). 7.4 Absolute neutrophil count (ANC) ≥1.0 × 10^9/L (1000/mm^3). 7.5 Hemoglobin ≥9 g/dL. 7.6 Platelet count ≥75 × 10^9/L (75,000/mm^3). 7.7 International normalized ratio (INR) and activated partial thromboplastin time (aPTT) ≤1.5 × ULN, unless participant is receiving anticoagulant therapy. 7.8 Thyroid-stimulating hormone (TSH) within normal limits.
