Detailed Description
The mainstay of maintenance immunosuppression post-transplantation includes a calcineurin inhibitor, either cyclosporine or tacrolimus. The introduction of calcineurin inhibitors led to a significant improvement in graft and patient outcomes post solid organ transplantation. However, one of the severe limitations of this class of drugs, is its associated nephrotoxicity. Data from the Scientific Registry of Transplant Recipients reveal that the incidence of stage 4 chronic kidney disease or stage 5 Chronic Kidney Disease (CKD) after Orthotopic Liver Transplantation (OLT) at 1, 3, and 5 years is 8%, 14%, and 18%, respectively, increasing to approximately 25% by 10 years after transplantation.Furthermore, renal dysfunction is associated with a four-fold increase in patient mortality post solid organ transplantation.
Several calcineurin inhibitor sparing and minimizing regimens have been studied. Most recently, in the phase III, randomized study in de novo liver transplant recipients,demonstrated significantly improved renal function in the tacrolimus minimization arm (everolimus plus tacrolimus one year post transplant.In fact superior renal function was achieved with the tacrolimus minimization arm one month after randomization and was maintained to Month 12. With this pilot study, we aim to compare the efficacy of the standard immunosupression post liver transplant with Tacrolimus and Mycophenolic acid (Myfortic)with calcineurin sparing regimen using the combination of everolimus and enteric coated mycophenolic acid, as determined by the estimated Glomerular filtration rate (GFR) at one year post transplant, with acceptable rates of biopsy proven rejection.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Everolimus Conversion Arm
Everolimus will be initiated within 24 hours of baseline at a dose of 1 mg po BID (2 mg/day). Therapeutic Drug Monitoring will be performed throughout the study. Tacrolimus should be eliminated when the everolimus target range has been reached. Complete tacrolimus elimination will not occur earlier than 90 days post transplant and no later than 120 days post transplant. Enteric coated mycopenolic acid will be maintained for the duration of the study. Oral corticosteroids may not be eliminated sooner than 180 days post transplantation. Everolimus doses will be adjusted based on local lab results of everolimus trough levels. |

Active Comparator: Standard Tacrolimus Immunosuppresion Arm
Subjects will be maintained on standard maintenance immunosuppression per local protocol, consisting of a tacrolimus plus enteric coated mycophenolic acid. Oral corticosteroids may not be eliminated sooner than 180 days post transplantation. Tacrolimus doses will be adjusted based on local lab results of tacrolimus trough levels. |
