Protection of trial subjects |
This clinical study was written, conducted and reported in accordance with the protocol, ICH GCP Guidelines, and applicable local regulations, including the European Directive 2001/20/EC, on the protection of human rights, and with the ethical principles that have their origin in the Declaration of Helsinki. Astellas ensures that the use and disclosure of protected health information (PHI) obtained during a research study complies with the federal, national and/or regional legislation related to the privacy and protection of personal information.This protocol was reviewed and approved by the Institutional Review Board (IRB) of the participating institutions. The study was conducted in compliance with Good Clinical Practice (GCP) and in accordance with ethical principles that have their origin in the Declaration of Helsinki. The subject’s legal guardian read and signed an IRB-approved informed consent form and Health Insurance Portability and Accountability Act (HIPAA) authorization prior to initiation of any study-related procedures. Subjects, 7 to 12 years of age, were fully informed and signed an IRB-approved assent form/authorization.

Background therapy |
This study included a 1-week exposure to Prograf, with participants already on a stable dose of Prograf-based immunosuppressive therapy for liver transplantation. All immunosuppressants and corticosteroids used in combination with Prograf at baseline/day 1 were maintained at constant doses throughout the pharmacokinetic (PK) treatment period. Once the day 14 PK visit was completed, corticosteroid and immunosuppressant dose adjustments were permitted. Use of sirolimus, intravenous methylprednisolone, or any investigational immunosuppressant was prohibited during the PK treatment period. | ||

The primary measure of exposure for Tacrolimus (AUC0-24 - Area Under the Concentration-time Curve From Time 0 to 24 Hours) | ||||||||||||
End point description |
The primary measure of exposure was area under the concentration-time curve from 0 to 24 hours (AUC0-24 (ng*hr/mL)). 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.

Statistical Analysis (AUC0-24) for Tacrolimus | ||||||||||||
Statistical analysis description |
The method of analysis of variance was used for the comparisons of AUC0-24. Exposure at steady state was used for tacrolimus (Prograf) (defined as Day 7) and for tacrolimus MR (defined as Day 14). The natural log (ln) was used to transform AUC0-24 prior to analysis and the results were transformed back to the original scale for the presentation of results. For this statistical analysis 18 participants were analysed.
