The purpose of this trial was to demonstrate the efficacy and safety of everolimus in combination with reduced tacrolimus, compared to tacrolimus control, in living donor liver transplant recipients.
This study was 24 month, multicenter study in 280 living donor liver transplant patients from Asia, Europe and Canada. The study has an long term extension in Japan and approximately 28 patients were to be included to evaluate the long-term efficacy and safety of concentration-controlled everolimus regimen plus reduced tacrolimus compared to standard tacrolimus in recipients of living donor liver transplants in Japan who participated in the CRAD001H2307 study. Data reported here are the CRAD001H2307 core study results and its extension (CRAD001H2307E1).

Everolimus was initiated at Week 4 post transplantation. The dose was adjusted to maintain the everolimus trough blood levels between 3-8 ng/mL for the duration of the study. Tacrolimus was reduced to 3-5 ng/mL.
Tacrolimus was initiated as soon as possible after transplantation according to approved labeling recommendations. The trough level should've been 5-15 ng/mL until randomization, 8-12 ng/mL from randomization until month 4 and after month 4 until end of study reduced to 6 -10 ng/mL.
Number of Participants With Composite Efficacy Failure of Treated Biopsy Proven Acute Rejection, Graft Loss or Death in Everolimus With Reduced Tacrolimus Group Compared to Standard Tacrolimus
Rate of composite efficacy failure of treated biopsy proven acute rejection (tBPAR ≥ RAI score 3), graft loss (GL) or death (D) in everolimus with reduced tacrolimus group compared to standard tacrolimus at 12 months
Time frame: 12 months post transplantation
Renal Function by Estimated Glomerular Filtration Rate (eGFR) From Randomization

Number of Participants With Time to Recurrence of HCC in Subjects With a Diagnosis of HCC at the Time of Liver Transplantation
Patients transplanted for HCC or with HCC diagnosed at time of transplantation were monitored for HCC recurrence according to local practice. For example routine laboratory monitoring/tests, tumor markers, hepatic ultrasound, computed tomography scans (CAT, CT) or MRI (especially Fe-MRI) on a regular basis per local practice.

Composite Efficacy Failure of Treated Biopsy in Everolimus With Reduced Tacrolimus Group Compared to Standard Tacrolimus in Patients From Japan Only
Rate of composite efficacy failure of treated biopsy in everolimus with reduced tacrolimus group compared to standard tacrolimus from randomization in core study up to 36 months in the extension study. Composite endpoint = treated BPAR, graft loss or death. AR = Acute rejection; tAR = treated AR; BPR = biopsy proven rejection; BPAR = biopsy proven acute rejection; tBPAR = treated BPAR
