E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that immunosuppressant combination based on tacrolimus + everolimus in stable renal transplant patients (> 12 months after transplant) achieves a greater reduction of left ventricular hypertrophy (LVH) compared to the “standard” combination based on tacrolimus + mycophenolate mofetil |
Demostrar que la combinación inmunosupresora basada en tacrolimus + everolimus en pacientes trasplantados renales estables (> de 12 meses desde el trasplante) consigue una mayor reducción de la hipertrofia ventricular izquierda (HVI) comparada con la combinación “standard” basada en tacrolimus + micofenolato mofetil |
|
E.2.2 | Secondary objectives of the trial |
To determine that the study combination improves cardiovascular profile by evaluating the improvement of pulse wave velocity,blood pressure, the measurement of intra-aortic pressure and determination of major cardiovascular events To demonstrate that the study combination improves kidney function by measuring serum creatinine, calculated GFR and clearance of iohexol To compare the CV and immunological profile in the two treatment groups using the following biomarkers: HbA1c, troponin I, NT-proBNP, CRP, FGF23 and development of donor specific antibodies (DSA). Markers related to myocardial fibrosis and arterial stiffness are also assessed: MMP-2, -9, PIINP, CITP To compare efficacy between the two treatment groups assessing: BPAR, graft loss, death and loss to follow up. To assess the safety of the combination by evaluating adverse events (AEs), Diabetes Mellitus and lipid profile |
