Dosing Requirements of Astagraf XL® in African American Kidney Transplant Recipients

Registration Number
NCT02953873
Lead Sponsor
Medical University of South Carolina
Brief Summary

Compare the difference in dose-normalized trough and total daily dose necessary to reach the steady state therapeutic goal after conversion from tacrolimus IR to Astagraf XL® in African American kidney transplant recipients.

Detailed Description

The purpose of this study is to compare the difference in medication dosage and total daily dose necessary of Astagraf XL® in order to reach therapy goal, when taken with other medications that are routinely used for kidney transplantation, which may stop the development of a substance that can cause long-term damage to the transplanted kidney. African American kidney transplant patients aged 18 and above who are underwent a kidney transplant are eligible to participate. The duration of the study is 3 months.
