Summary

The immune system is the body's defense against infection and other disease. After transplantation, the body sees the new organ as "foreign" and tries to destroy or "reject" it. Immunosuppressive medications help to prevent the immune system from attacking a transplanted organ. The primary purpose of this study is to investigate the impact of two maintenance immunosuppressive regimens. Subjects who enroll in this study will be randomly selected to have tacrolimus and everolimus (group 1) or tacrolimus and mycophenolate mofetil (group 2) as their immunosuppression medication.

This study will enroll adult patients who are scheduled to receive a kidney transplant.

The study is designed to understand the mechanisms of Everolimus in regards to kidney function in transplant recipients. The investigators hypothesis is that decreased exposure to Tacrolimus to the immune system will then translate in better renal allograft function.

Conditions

  • End Stage Renal Failure With Renal Transplant

Interventions

DRUG

Tacrolimus with MMF

Standard dose Tacrolimus and MMF. This will follow standard of care procedures at Northwestern Memorial Hospital's Comprehensive Transplant Center. MMF trough or area under the concentration time curve (AUC) shall not be used to adjust dosing. In this group, Tacrolimus will be initiated according to our practice. The Tacrolimus dose will be adjusted from day 3 on to achieve a target whole blood trough concentration of 8 ng/mL to 10 ng/mL. From month 2 until Month 6, the target Tacrolimus trough level will be reduced to 6 ng/mL to 8 ng/mL. After month 6, the target level of Tacrolimus will be reduced to 4 ng/mL to 8 ng/mL.

DRUG

Group 2: Tacrolimus with Everolimus.

From day 5 on, the starting dose of Everolimus (0.75 mg bid) will be increased if the trough level is \< 3 ng/mL, or reduced if the trough level is \> 8 ng/mL. Tacrolimus will be initiated according to our practice. In this treatment arm, the Tacrolimus dose will be adjusted from day 3 on, to a target whole blood trough concentration of 4 ng/mL to 7 ng/mL. From month 2 until Month 6, the target Tacrolimus trough level will be 3 ng/mL to 6 ng/mL. After month 6, the Tacrolimus dose should be adjusted in order to achieve a target trough level of 2 ng/mL to 5 ng/mL. MMF dose will be initiated as 1 g b.i.d. (2 g/day). Adjustments should be made for adverse events including but not limited to gastrointestinal intolerance and a decrease in white blood cell (WBC).
