• Hemoglobin ≥ 9 g/dl
• Absolute neutrophil count (ANC) ≥ 1 x 10\^9/L
• Platelets ≥50 x 10\^9/L (patient without BM involvement) and 30 x 10\^9/L (patient with BM involvement)
• Total bilirubin ≤1.5 times the upper limit of normal (ULN)
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 x ULN if known liver involvement
• Creatinine ≤ 1.5 mg/dL OR calculated creatinine clearance ≥ 50 mL/min (as calculated by the Cockcroft-Gault method)
• Use of an effective means of contraception for female patients of child-bearing potential, and all male partners.
