Trial Outcomes & Findings for A Study of a Modified-Release Tacrolimus Based Immunosuppression Regimen in Stable Pediatric Liver Transplant Patients (NCT NCT00282256)

NCT ID: NCT00282256

Last Updated: 2013-10-17

Results Overview

The area under the concentration-time curve was calculated from whole blood tacrolimus concentrations for both tacrolimus and tacrolimus MR at steady state using the linear trapezoidal rule. The AUC0-24 for tacrolimus was calculated as the sum of the AUC0-12 and AUC 12-24 for the morning and afternoon doses.

Tacrolimus MR
Participants continued to receive their stable twice daily dose of tacrolimus twice daily on Day 1 through Day 7 and on Day 8 were converted to tacrolimus modified release (MR) once-daily in the morning for 7 days on a 1:1 (mg:mg) basis for their total daily dose. Patients who completed the 2-week pharmacokinetic treatment period were eligible to continue receiving tacrolimus MR as part of the extension treatment period of the study.

PRIMARY outcome

Timeframe: For tacrolimus, Day 7 at 0 (pre-dose), 0.5, 1, 2, 3, 6, 8, 12 (pre-dose), 13, 14, 15, 18, 20, and 24 hours. For tacrolimus MR, Day 14 at pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 15, 18, 20, and 24 hours post-dose.

Population: The pharmacokinetic evaluable set was defined as all patients who completed both pharmacokinetic profiles: one for tacrolimus, and one for tacrolimus MR. A complete pharmacokinetic profile was considered to be a profile that was adequate to determine AUC0-24, Cmax, and Cmin.

The area under the concentration-time curve was calculated from whole blood tacrolimus concentrations for both tacrolimus and tacrolimus MR at steady state using the linear trapezoidal rule. The AUC0-24 for tacrolimus was calculated as the sum of the AUC0-12 and AUC 12-24 for the morning and afternoon doses.

Biopsy-confirmed acute rejection (BCAR) is defined as an episode of acute liver allograft rejection that was confirmed by biopsy results and was Banff grade ≥ I. Biopsies were graded by the pathologist at the clinical site according to the 1997 Banff criteria for grading of acute liver allograft rejection: Indeterminate: Portal inflammatory infiltrate that fails to meet the criteria for diagnosis of acute rejection; Grade I (Mild): Rejection infiltrate in a minority of the triads that is generally mild and confined within the portal spaces; Grade II (Moderate): Rejection infiltrate, expanding to most or all of the triads; Grade III (Severe): Rejection infiltrate, expanding to most or all of the triads, with spillover into periportal areas and moderate to severe perivenular inflammation that extends into the hepatic parenchyma and is associated with perivenular hepatocyte. necrosis

An adverse event (AE) is defined as any reaction, side effect or other untoward medical occurrence, regardless of the relationship to study drug which occurred during the conduct of a clinical study. Clinically significant adverse changes in clinical status, routine laboratory studies or physical examinations were considered adverse events. A serious adverse event was any adverse event occurring at any dose that resulted in any of the following outcomes: * Death * Life-threatening adverse event * Inpatient hospitalization or prolongation of existing hospitalization * Persistent or significant disability or incapacity * Congenital abnormality or birth defect * Important medical event.

Measure
Tacrolimus MR
n=18 participants at risk
Participants continued to receive their stable twice daily dose of tacrolimus twice daily on Day 1 through Day 7 and on Day 8 were converted to tacrolimus modified release (MR) once-daily in the morning for 7 days on a 1:1 (mg:mg) basis for their total daily dose. Patients who completed the 2-week pharmacokinetic treatment period were eligible to continue receiving tacrolimus MR as part of the extension treatment period of the study. The extended treatment period began on Day 15 and consisted of a single dose of tacrolimus MR once every morning through the end of the study.
