简要总结
The objective of the study is to determine the efficacy and safety of Everolimus conversion in liver transplantation. Most large US liver centers transplant patients with high Model for End-Stage Liver Disease (MELD) scores. However, many of the sponsored liver transplant trials in the US do not include patients with high MELD scores making it difficult to extrapolate these trial data to the patients cared for at larger liver transplant centers. The greatest potential benefit of mammalian target of rapamycin (mTOR) inhibitors is the avoidance of the side-effects of calcineurin-inhibitors, namely, renal insufficiency, diabetes and hypertension. Therefore, this protocol is designed to study the efficacy and safety of everolimus and Myfortic in liver transplant patients with high MELD scores at two large centers with a vast experience in the administration of mTOR inhibitors.

- •Recipients who are 18-70 years of age of a primary or secondary liver transplant from a deceased donor.
- •Allograft is functioning at an acceptable level by the time of randomization as defined by the Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Total Bilirubin levels ≤3 times Upper Limit of Normal (ULN), and Alkaline Phosphatase (AlkP) levels ≤ 5 times ULN.
- •Ability and willingness to provide written informed consent and adhere to study regimen.

研究组 & 干预措施
Everolimus, Myfortic and Tacrolimus
Tacrolimus discontinued (within 8 weeks of initiation of everolimus conversion).
Everolimus 1mg BID started (targeted trough 6-12ng/mL). Patients must have an everolimus concentration between 6-12ng/mL before tacrolimus is discontinued.
Myfortic 360-720 mg BID
干预措施: Everolimus, Myfortic and Tacrolimus (Drug)
Myfortic and Tacrolimus
Normal Care: Myfortic BID 360-720 mg Tacrolimus (5-12ng/mL)
干预措施: Myfortic and Tacrolimus (Drug)
结局指标
主要结局
proven acute rejection
时间窗: 12 months
1. To evaluate the use of a calcineurin-free immunosuppressive regimen utilizing concentration-controlled everolimus and mycophenolic acid (Myfortic) (Arm #12), in order to compare rates of the composite efficacy endpoint (biopsy proven-acute rejection, graft loss, and death) to the rates in the CNI-containing control arm (Arm #21) at 12 months post conversion to everolimus.
