Purpose
An exploratory study of the efficacy and safety of a regimen consisted of Everolimus plus low tacrolimus for the immunosuppression in renal transplantation in the elderly.
To evaluate the pharmacokinetics of immunosuppressants that have been little studied in this population.
To evaluate whether the polymorphism of the genes that determine the expression of metabolizing enzymes and transporters of xenobiotics interfere in the elderly, also in the younger population, absorption and metabolism of immunosuppressants.
To evaluate the potential minimization of immunosuppression in this population refers to how does the re-population of peripheral lymphocytes, in this age group, after the use of lymphocyte-depleting agents such as thymoglobulin and subsequently maintained with two regimes.
Clarify which markers of renal filtration exist today, cystatin C and serum creatinine, is the right to monitor renal function in elderly transplanted.

Experimental: Everolimus
Number of patients: 45 Everolimus: initial dose of 1 mg BID. Doses will be adjusted in order to maintain Everolimus whole blood trough concentrations between 3-8 ng/ml. Tacrolimus: initial dose of 0.1 mg/kg/day. Doses will be adjusted in order to maintain Tacrolimus whole blood trough concentrations between 2- 4 ng/ml thereafter. Corticosteroids: as clinical practice. |
Drug: Everolimus
This is a 5-years prospective, randomized, exploratory, single-center, parallel group trial that includes renal transplanted elderly patients (≥ 60 years old) randomized between months 1 and 3 after transplantation to be maintained under MPS/TAC regimen or be switched to EVL/low-TAC. Everolimus: initial dose of 1 mg BID. Doses will be adjusted in order to maintain Everolimus whole blood trough concentrations between 3-8 ng/ml. Tacrolimus: initial dose of 0.1 mg/kg/day. Doses will be adjusted in order to maintain Tacrolimus whole blood trough concentrations between 2- 4 ng/ml thereafter. Corticosteroids: as clinical practice. Other Names:

Detailed Description:
Objectives: The objective of this study is to evaluate the safety and efficacy of everolimus (EVL) combined with low dose of Tacrolimus in comparison with Mycophenolate Sodium (MPS) combined with standard dose of Tacrolimus as immunosuppressive therapy for elderly recipients of kidney transplantation.
Comparison between the two study arms of:
Primary Objective:
1. Composite efficacy failure demonstrated by graft loss and/or death with functional graft and/or GFR (Glomerular Filtration Rate determined by EDTA-Cr51) < 50 ml/min at the end of first year after transplantation and every year until the fifth year.
Secondary Objectives:
- Pharmacokinetic study of immunosuppressive drugs (Tacrolimus, Everolimus and Mycophenolate Sodium) in the study population at days 7, 30, 60, 67, 90 and 180 post-transplant.
- Serious adverse events (as internationally defined by ICH-GCP) every year, for five years.
- Biopsy proven acute rejection rated every year, for five years.
- Identify which of the renal filtration markers existing today, Cystatin C or Serum Creatinine, is more adequate to monitor renal function in elderly transplant and to develop abbreviated equations for eGFR from day 7 on.
- Evaluation of other metabolic effects (bone density at month 12 post-transplant; vitamin D at months 2 and 12 post-transplant; and gonadal function at months 1 and 12 post-transplant) and Quality of Life at months 1, 12, 18, 24, 36, 48 and 60 post-transplant in the study population.
- Left Ventricular Mass (LVM) and Left Ventricle Ejection Fraction (LVEF) measured by echocardiography at the end of the first year.
