Prospective Study to Measure Vascular Parameters (Ancillary Study of ADEQUATE) (ADEQUATEartère)

May 30, 2014 updated by: University Hospital, Tours

Effect of Advagraf on Arterial Stiffness and on Vascular Fibrosis Plasma Markers on de Novo Renal Transplant Patients

The purpose of this study is to compare parallel-group effects between 4 months and 12 months post-transplantation 2 values of target residual concentrations of Advagraf on vascular parameters in de novo renal transplant patients.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A - tacrolimus half-dose

Immunosuppressive 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
Drug: Tacrolimus targeted half-dose
Other Names:
  • Advagraf®
Experimental: Group B - tacrolimus unchanged dose
Immunosuppressive 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
Drug: Tacrolimus targeted plain dose
Other Names:
  • Advagraf®

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Aorta stiffness at one year post-tranplantation
Time Frame: 12 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.
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Blood pressure
Time Frame: 12 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.
12 months
Endothelial activation at one year post-tranplantation
Time Frame: 12 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.
12 months
