Cyclosporine A C-2h Monitoring Versus Tacrolimus C-0h Monitoring in de Novo Liver Transplant Recipients

Phase 4

Completed

Conditions: Liver Transplant

Interventions: Drug: Cyclosporine A
Drug: Tacrolimus
Drug: Basiliximab
Drug: Methylprednisolone
Drug: Prednisone

Registration Number: NCT00149994

Lead Sponsor: Novartis Pharmaceuticals

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.

Arm && Interventions

Group	Intervention	Description
Cyclosporine A	Cyclosporine A	Cyclosporine A was given in a twice-daily schedule 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, as close as possible to 15mg/kg/day. After the first oral administration, the dose of Cyclosporine A was adjusted to bring the sample taken 2 hours after oral dose (C-2h) level into the target range by Days 3-5 post-transplantation. C-2h target ranges post-transplantation: 0-3 months: range of 800-1200 ng/ml with midpoint of 1000 ng/ml; 4-6 months: range of 700-900 ng/ml with midpoint of 800 ng/ml; \> 6 months: range of 500-700 ng/ml with midpoint of 600 ng/ml is recommended. During the course of the study, the dose of Cyclosporine A was adjusted as necessary to achieve and maintain the C-2h blood Cyclosporine A (CsA) concentrations within the target ranges.
Cyclosporine A	Methylprednisolone	Cyclosporine A was given in a twice-daily schedule 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, as close as possible to 15mg/kg/day. After the first oral administration, the dose of Cyclosporine A was adjusted to bring the sample taken 2 hours after oral dose (C-2h) level into the target range by Days 3-5 post-transplantation. C-2h target ranges post-transplantation: 0-3 months: range of 800-1200 ng/ml with midpoint of 1000 ng/ml; 4-6 months: range of 700-900 ng/ml with midpoint of 800 ng/ml; \> 6 months: range of 500-700 ng/ml with midpoint of 600 ng/ml is recommended. During the course of the study, the dose of Cyclosporine A was adjusted as necessary to achieve and maintain the C-2h blood Cyclosporine A (CsA) concentrations within the target ranges.
Tacrolimus	Tacrolimus	Tacrolimus was given on a twice-daily schedule at 12-hour intervals which had to be maintained throughout the study period. Tacrolimus was administered within the first 24 hrs postoperatively (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 patient can swallow. The initial dosing level was determined by the patient's overall post-operative condition. During the course of the study, the dose of tacrolimus was adjusted as necessary to achieve and maintain the pre-dose blood concentration (C-0h) (trough) tacrolimus concentrations. C-0h target ranges post-transplantation: 0-3 months: 10-15 ng/ml; 4-6 months: 5-10 ng/ml; \> 6 months: range of 5-10 ng/ml is recommended.
Cyclosporine A	Prednisone	Cyclosporine A was given in a twice-daily schedule 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, as close as possible to 15mg/kg/day. After the first oral administration, the dose of Cyclosporine A was adjusted to bring the sample taken 2 hours after oral dose (C-2h) level into the target range by Days 3-5 post-transplantation. C-2h target ranges post-transplantation: 0-3 months: range of 800-1200 ng/ml with midpoint of 1000 ng/ml; 4-6 months: range of 700-900 ng/ml with midpoint of 800 ng/ml; \> 6 months: range of 500-700 ng/ml with midpoint of 600 ng/ml is recommended.

Primary Outcome Measures

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