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.

Masking
NONE
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
Myfortic BID 360-720 mg Tacrolimus (5-12ng/mL)

proven acute rejection
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.
Time frame: 12 months
