Trial Summary

What is the purpose of this trial?

This trial is testing Tacrolimus XR, a slow-release medication, in heart transplant recipients. The goal is to see if it reduces kidney damage by maintaining steady drug levels and avoiding high peaks. Researchers hope this will improve kidney function without harming the transplanted heart. Tacrolimus (FK 506) is a novel immunosuppressive agent that has been in clinical use for solid organ transplantation since 1989.

Eligibility Criteria

This trial is for heart transplant recipients aged 18-80, within 10 years post-transplant, currently on IR Tacrolimus with stable function and a baseline kidney filtration rate (eGFR) over 30. It excludes those under 18 or over 80, with active cancer, recent rejection episodes, multiple organ transplants or more than a decade since their heart transplant.

Inclusion Criteria

I am currently on IR Tacrolimus medication.
Your kidney function, measured as eGFR, is higher than 30 mL/min/1.73m2.
I received a heart transplant within the last 10 years and my condition is stable.

Exclusion Criteria

I had a heart transplant over 10 years ago, or I have cancer or rejection issues post-transplant.
I am under 18 years old.
I have received transplants for more than one organ.

Treatment Details

Interventions

  • Tacrolimus
Trial Overview The study tests the effects of switching from Immediate Release (IR) Tacrolimus to Extended Release (XR) Tacrolimus in heart transplant patients. The goal is to see if XR Tacrolimus causes less kidney tubular injury due to its lower peak levels but similar overall exposure as IR.
