Summary

This trial is comparing two different tacrolimus regimens in kidney transplant patients to see which is more effective and safe.

Who is the study for?
This trial is for African American individuals with a BMI ≥19, undergoing their first or second kidney transplant. They must be using certain immunosuppressants and can have Hepatitis B or C. Excluded are those with severe GI issues affecting drug absorption, HIV positive, poor medical adherence history, women not using contraception unless exempted by specific criteria, anyone over 75 years old, recipients of more than two kidney transplants, and those allergic to Tacrolimus.
What is being tested?
The study compares the effects on blood vessel function between two forms of the drug Tacrolimus: extended-release tablets taken once daily (Envarsus XR®) versus immediate-release capsules taken twice daily (Prograf®). It measures how well blood vessels respond to heartbeats before and after treatment in kidney transplant patients.
What are the potential side effects?
Tacrolimus may cause side effects such as tremors, high blood pressure, kidney problems, infections due to weakened immune system response from the medication. The risk of diabetes and gastrointestinal disturbances might also increase.

Trial Design

2Treatment groups
Active Control
Group I: Extended Release Tacrolimus TabletsActive Control1 Intervention
Dosed once daily in the morning and started at a dose of 0.14 mg/kg/day by the first day after kidney transplant (post-operative day 1). This medication will be given with rabbit antithymocyte globulin (rATG) induction, oral mycophenolate mofetil (MMF) and oral steroids to help prevent rejection. These medications will be ordered per standard of care both inpatient and outpatient.
Group II: Immediate Release Tacrolimus CapsulesActive Control1 Intervention
Dosed twice daily 12 hours apart and started at a dose of 0.1mg/kg/day by the first day after kidney transplant (post-operative day 1). This medication will be given with rabbit antithymocyte globulin (rATG) induction, oral mycophenolate mofetil (MMF) and oral steroids to help prevent rejection. These medications will be ordered per standard of care both inpatient and outpatient.
