- Adequate hepatic function as evidenced by the following serum chemistry values: total bilirubin, ULN. If total bilirubin is greater than (>) ULN, measure indirect bilirubin to evaluate for Gilbert's syndrome (if direct bilirubin is within normal range, participant may be eligible) ALP 2.5 x ULN; Trabectedin: if the ALP is >2.5 x ULN, then an ALP liver fraction or 5-nucleotidase must be obtained and ULN, AST and ALT 2.5 ULN
