Arm
(Active Comparator)
At the time of transition patients randomized into this arm of the study will receive loading doses of sirolimus for two days and then 5mg PO daily. Twenty-four hour troughs will be checked per the schedule to ensure and monitor the therapeutic concentrations of 8-12ng/ml. Patients randomized into this arm of the study will continue their current dosing regimen and frequency of mycophenolate mofetil. Serum trough level monitoring of mycophenolic acid will not be performed unless clinically warranted per standard of care and dosage adjustments from such levels will be made only with consent of the study primary investigator.
rapamune, mycophenolate mofetil and steroid rapamune (Sirolimus)
At the time of transition patients randomized into this arm of the study will receive loading doses of sirolimus for two days and then 5mg PO daily. Twenty-four hour troughs will be checked per the schedule to ensure and monitor the therapeutic concentrations of 8-12ng/ml. Patients randomized into this arm of the study will continue their current dosing regimen and frequency of mycophenolate mofetil. Serum trough level monitoring of mycophenolic acid will not be performed unless clinically warranted per standard of care and dosage adjustments from such levels will be made only with consent of the study primary investigator.
(Active Comparator)
Tacrolimus dosing is based on 12-hour whole blood trough concentrations. Target blood concentration is 2-5 ng/ml. At the time of transition patients randomized into this arm of the study will receive loading doses of Sirolimus for two days and then 5mg PO daily. Twenty-four hour troughs will be checked per the schedule to ensure and monitor the therapeutic concentrations of 8-12ng/ml.
tacrolimus, sirolimus and steroid tacrolimus (Prograf)
Tacrolimus dosing is based on 12-hour whole blood trough concentrations. Target blood concentration is 2-5 ng/ml. At the time of transition patients randomized into this arm of the study will receive loading doses of Sirolimus for two days and then 5mg PO daily. Twenty-four hour troughs will be checked per the schedule to ensure and monitor the therapeutic concentrations of 8-12ng/ml.

time frame: 12 months

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - At least 18 years of age and able to give informed consent - African-American ethnicity - Received a first or second non-ECD cadaveric or living donor renal transplant - Transplant occurred during the past 6 to 24 weeks - Patient has stable graft function, defined as no change of greater than 30% of baseline serum creatinine during the past month and no acute rejection in the past 6 weeks - Estimated GFR using the modified MDRD equation of at least 40 mL/min10 at time of enrollment into the study - Currently receiving tacrolimus, mycophenolate mofetil (at least 1 gm per day), and corticosteroids as their immunosuppression regimen.

Additional Information

Official title A Pilot Study Comparing Two Different Sirolimus-based Transition Regimens in African-American Renal Transplant Recipients
Principal investigator Charles Bratton, MD
Description A major concern in transplantation is finding a successful regimen of medications to lower the potential for the body to reject the newly transplanted organ. The regimens in kidney transplantation include tacrolimus, sirolimus, mycophenolate mofetil and steroids. This study will compare the effectiveness and safety of a regimen including Sirolimus, Prograf, and steroids compared to a regimen including Sirolimus, Cellcept and steroids. These regimens have already been researched in the Caucasian population, and both drug regimens are FDA approved. This study's focus is on the effectiveness and safety of these regimens in African-Americans.
