To address the pharmacokinetic profiles of everolimus and tacrolimus in combination in de novo kidney transplant recipients, comparing 1.5 and 3 mg per day of everolimus in fixed doses. For comparison purposes, pharmacokinetic profiles will be performed at first dose (abbreviated), 4th day, 14th day, and 42nd day post-transplantation. Patients will receive triple therapy steroids, tacrolimus and everolimus. Tacrolimus will be administered at a dose of 0.15 mg/kg/day to achieve 10-15 ng/ml 14 days, and 5-10 thereafter. During the first 6 weeks (the PK study period) everolimus will be assigned to fixed dose of 0.75 or 1.5 mg bid. After day 42, everolimus will be adjusted for 3-8 ng/ml and tacrolimus minimized to optimize graft function. Efficacy and safety parameters at 6 months post-transplantation will be secondary endpoints.
The purpose of this study is to address the pharmacokinetic (PK) profiles of everolimus and tacrolimus in combination in de novo kidney transplant recipients, comparing 1.5 and 3 mg per day of everolimus in fixed doses. For comparison purposes, pharmacokinetic profiles will be performed at first dose (abbreviated), 4th day, 14th day, and 42nd day post-transplantation.
