Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A study to assess the pharmacokinetics, safety and effectiveness of tacrolimus in stable kidney transplant patients converted from a Prograf® based immunosuppression regimen to a modified release tacrolimus based immunosuppression regimen.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase II open-label, multi-center conversion study in stable, adult kidney transplant recipients to assess the pharmacokinetics, safety and effectiveness of tacrolimus in stable kidney transplant patients converted from a Prograf® based immunosuppression regimen to a modified release tacrolimus based immunosuppression regimen.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Tacrolimus Modified Release

Participants were enrolled into the study on their stable twice-daily (bid) dose of tacrolimus on Day 1 and continued to receive a stable bid dose of tacrolimus through Day 7. Participants then converted to Tacrolimus Modified Release (MR), administered once daily at an equivalent dose to the patient's previous stable total daily dose of tacrolimus. Participants who completed the 4-week pharmacokinetic treatment period with tacrolimus MR could continue receiving tacrolimus MR as part of the extended treatment period of the study. Dose adjustments were allowed in order to maintain tacrolimus trough concentrations within the target range of 5 to 15 ng/mL and for clinical reasons.
