11. Patients must have adequate organ function (Hemoglobin ≥ 8 g/100 ml, Neutrophils ≥ 1,000/mm3, Platelets ≥ 75,000/mm3, total bilirubin \<1.5 times the upper limit of normal (ULN) for age (except for Gilbert's syndrome patients), serum alanine aminotransferase (ALT) \<2.5 ´ ULN for age, aspartate aminotransferase (AST) \<2.5 ´ ULN for age , serum creatinine £1.5 x ULN for age
