Brief summary

The purpose of this study is to determine whether cyclosporine A (in a micro emulsion formulation) monitored by sample taken 2 hour after oral dose (C-2h) will show equivalent or superior efficacy compared to tacrolimus monitored by pre-dose blood concentration (C-0h). In addition this study will assess the safety and tolerability of a cyclosporine A regimen based on C-2h monitoring in comparison to the standard tacrolimus regimen.

Interventions

DRUGCyclosporine A
DRUGTacrolimus
DRUGBasiliximab

Each patient was given two 20mg doses of Basiliximab as intravenous bolus injection at Day 0 and Day 4 post-transplant surgery.

DRUGMethylprednisolone

Methylprednisolone was given as an intravenous bolus of 500mg during transplant surgery

DRUGPrednisone

Post-operatively prednisone was tapered from an initial dose of 20mg/day to zero at 3 months or continued at 5-10mg if the indication for Orthotopic Liver Transplantation (OLTx) was of auto-immune nature.

Inclusion criteria

* About to undergo a primary liver transplant (including living donor, non-heart beating donor and split liver). * Age between 18 and 75 years. * Expected to be able to receive the first oral dose of CNI within the first 24 hours post-transplantation (Tx)

Exclusion criteria

MeasureTime frameDescription
Percentage of Participants With an Occurrence of Biopsy Proven Acute Rejection (BPAR) During the First 3 Months Post de Novo Liver Transplantation.Month 3A BPAR is defined when the investigator had a suspicion of an acute rejection, where the final clinical diagnosis confirmed the occurrence of an acute rejection, where a biopsy was performed that confirmed the presence of an acute rejection, and where anti-rejection treatment intervention was initiated. The efficacy measured the first rejections (clinically and biopsy proven rejections) at 3 months.

ArmCount
Cyclosporine A
Cyclosporine A was given twice-daily at 12-hour intervals. It was administered within the first 4 hours post-operatively (study day 1), at an initial dose of 10-15mg/kg/day in two doses. Cyclosporine A was adjusted to bring the 2 hour after oral dose (C-2h) level into the target range by Days 3-5 post-transplantation. The dose of Cyclosporine A was adjusted to achieve and maintain post transplantation C-2h levels 0- 3 months: 800- 1200 ng/mL, 4- 6 months: 700- 900 ng/mL and \>6 months: 500- 700 ng/mL. Each participant was given two 20 mg doses of Basiliximab as intravenous bolus injection at Day 0 and Day 4 post-transplant surgery. Methylprednisolone was given as an intravenous bolus of 500 mg during transplant surgery. Post-operatively prednisone was tapered from an initial dose of 20 mg/day to zero at 3 months or continued at 5-10 mg if the indication for Orthotopic Liver Transplantation (OLTx) was of auto-immune nature.

Tacrolimus
Tacrolimus was given twice-daily at 12-hour intervals. Tacrolimus was administered within the first 24 hrs post- operatively (Study Day 1) at an initial dose of 0.1-0.15 mg/kg/day in two divided oral doses either by mouth or via an enteral feeding tube until the participant can swallow. The initial dosing level was determined by the participants's overall post-operative condition. The dose of tacrolimus was adjusted to achieve and maintain the pre-dose C-Oh (trough) target ranges post-transplantation 0-3 months: 10-15 ng/ml; 4-6 months: 5-10 ng/ml and \> 6 months: 5-10 ng/ml . Each participant was given two 20 mg doses of Basiliximab as intravenous bolus injection at Day 0 and Day 4 post-transplant surgery. Methylprednisolone was given as an intravenous bolus of 500 mg during transplant surgery. Post-operatively prednisone was tapered from an initial dose of 20 mg/day to zero at 3 months or continued at 5-10 mg if the indication for OLTx was of auto-immune in nature.

Primary

Percentage of Participants With an Occurrence of Biopsy Proven Acute Rejection (BPAR) During the First 3 Months Post de Novo Liver Transplantation.

A BPAR is defined when the investigator had a suspicion of an acute rejection, where the final clinical diagnosis confirmed the occurrence of an acute rejection, where a biopsy was performed that confirmed the presence of an acute rejection, and where anti-rejection treatment intervention was initiated. The efficacy measured the first rejections (clinically and biopsy proven rejections) at 3 months.
