This 5-year study consisted of a 2-year enrolment period and a 3-year follow-up period. Patients will be screened for eligibility prior to liver transplantation. Patients who have undergone successful liver transplantation will be initiated on a tacrolimus-based regimen that includes MMF and/or Steroids and enter the baseline period (between 3 and 7 days post-transplantation). At 30 (± 5) days post-transplantation, patients who meet additional randomization inclusion/exclusion criteria will be randomized into 2 groups of this study. In the first group, patients will be maintained on a tacrolimus-based (sirolimus-free) immunosuppression regimen. The second group will be treated with sirolimus-based (tacrolimus-free) immunosuppression regimen. For patients in both groups, mycophenolic acid prodrugs like mycophenolate mofetil (MMF) and steroids are initiated at the time of liver transplantation according to local practice. Steroids reduction is encouraged by 3 months post liver transplantation.~In the first year after randomization all patients will be followed up after month 1, 2, 3, 4, 5, 6, 8, 10 and 12. After that, patients are followed every 3 months. Tacrolimus and sirolimus trough levels in patients of both groups will be tested and adjusted if need be at each follow-up date to achieve the desired steady-state trough levels.~The primary endpoint is defined as HCC recurrence-free time interval between the date of liver transplantation and the date of HCC recurrence or death; patients who are alive and recurrence-free at the end of month 36 will be censored at the time of their last follow-up date. HCC recurrence can be determined during the entire follow-up period.
This is a multicenter, open-label, randomized, controlled clinical trial, in order to compare sirolimus-based (tacrolimus-free) versus tacrolimus-based (sirolimus-free) immunosuppression regimen for Hepatocellular Carcinoma (HCC) patients after liver transplantation.
