Arm && Interventions
GroupInterventionDescription
Group A - tacrolimus half-doseTacrolimus targeted half-doseImmunosuppressive strategy with 50 % reduction of Advagraf® daily dose at M4 (randomization) and unchanged MMF dose. Targeted tacrolimus trough level are to be higher than 3 ng/mL . If the dose is not in adequation with the dispensable units, the prescribed dose will be the closest higher dose. Drug: Tacrolimus targeted half-dose
Group B - tacrolimus unchanged doseTacrolimus targeted plain doseImmunosuppressive strategy will remain identical after randomization (M4): unchanged Advagraf® and MMF doses. Targeted tacrolimus trough level are to be between 7 and 12 ng/mL Drug: Tacrolimus targeted plain dose
Primary Outcome Measures
NameTimeMethod
Aorta stiffness at one year post-tranplantation12 months

Evaluate the aorta stiffness at 1 year post-renal transplantation and its evolution in patients who received a half reduction of their daily dose of Advagraf ® 4 months after transplantation compared with patients whose dose has not been divided.

Secondary Outcome Measures
NameTimeMethod
Endothelial activation at one year post-tranplantation12 months

Evaluate peripheral and central blood pressures, the impact of reflected pressure waves and coupling cardiocirculatory (on the functional plan) and evaluate endothelial activation, factors promoting the vascular fibrosis and oxidant stress level (on biological plan) at 1 year post-renal transplantation and their evolution in patients who received a hal reduction of their daily dose Advagraf ® to four months of the transplant when compared with patients whose dose was not divided.

Blood pressure12 months

Evaluate peripheral and central blood pressures, the impact of reflected pressure waves and coupling cardiocirculatory (on the functional plan) and evaluate endothelial activation, factors promoting the vascular fibrosis and oxidant stress level (on biological plan) at 1 year post-renal transplantation and their evolution in patients who received a hal reduction of their daily dose Advagraf ® to four months of the transplant when compared with patients whose dose was not divided.
