The purpose of the study is to compare the safety and efficacy of two different tacrolimus based immunosuppressive regimens, one in combination with daclizumab, the other in combination with steroids, in recipients of suboptimal livers.

Pharmacokinetics of tacrolimus and bile composition will be measured in a subgroup of patients.

Open, multicentre, 1:1 randomised, parallel group phase III study to compare safety and efficacy of tacrolimus (FK506) with monoclonal anti-IL2R antibodies (daclizumab) vs tacrolimus (FK506) with steroids and evaluate pharmacokinetics in liver allograft recipients receiving suboptimal livers.

Patients receiving primary suboptimal liver allograft transplantation (from donors > 65 years and/or liver macrosteatosis >15%) will be randomised to one of the following treatment arms:

Group I: steroid bolus (intraoperative) monoclonal anti-IL2R antibodies (daclizumab) induction tacrolimus Group II: steroid bolus (intraoperative) tacrolimus steroids

Inclusion Criteria:

• Signed informed consent
• Adult patients scheduled to receive a liver transplant
• Donors older than 65 and/or has liver macrosteatosis >15%
• Female patients of childbearing potential agree to maintain effective birth control during the study and must have negative pregnancy test at baseline

Exclusion Criteria:

• Patient has previously received or is receiving an organ transplant other than liver, or a liver re-transplantation.
• Patient has significant, uncontrolled concomitant infections and/or severe diarrhea, vomiting, or active peptic ulcer
• Patient is receiving an auxiliary graft or a bio-artificial liver has been used.
• Any pathology or medical condition that can interfere with this protocol study proposal
• Other exclusion applies
