简要总结
The goal of this clinical trial is that validation of the non-invasive biomarkers of the AGORA algorithm should make it possible to select patients with a very low immunological risk of graft failure to authorize safe minimization of their immunosuppression for adult patients at one-year post kidney transplantation.
The main question of the AGORAC trial is to demonstrate the impact of TACROLIMUS minimization using AGORA algorithm compared to standard of care on the kidney function 18 months after the minimization period.

研究组 & 干预措施
Ultra-low TACROLIMUS arm
Ultra-low TACROLIMUS (TAC) arm based on MMF/MPA (Mycophenolate Mofetil/ Mycophénolic Acid) with or without CS (Cortico Steroid ) and TACROLIMUS to achieve 2-3.5 ng/ml trough levels during all the duration of the study.
干预措施: TACROLIMUS (Drug)
结局指标
主要结局
Improvement of the renal function at 18 months after "ultra" minimization of Tacrolimus
时间窗: Month 18
Improvement will be assessed by measured glomerular filtration rate (mGFR) iohexol clearance.
次要结局
- Appearance of de novo donor-specific alloantibody (DSA) (4 digits and MFI treshold >500)(Month 18)
- Incidence of biopsy-proven acute rejection (BPAR) according to the 2017 Banff classification (including borderline lesions)(Month 18)
- Type, severity and treatment of biopsy-proven acute rejection ( BPAR)(Month 18)
- Appearance or worsening of histological lesions of interstitial fibrosis and inflammatory tubular atrophy (IFTA) of study biopsy by considering that only patients with normal histology or with an IFTA-1 or 2will be randomized(Month 18)
- Prevalence of death, and graft loss (dialysis start or retransplantation) at end of study(Month 18)
- Prevalence of metabolic disorders: post-transplant diabetes mellitus (PTDM), dyslipidaemia and hypertension at end of study(Month 18)
- Treatment adherence consisting in monitoring immunosuppression adherence using Trackyourmed® to monitor individual variability tacrolimus intake(Month 18)
- Change in quality of life estimated using the EQ-5D ( EuroQol instrument - dimensions) questionnaire fulfilled by patients at baseline, Month 3, Month 6, Month 9, Month 12, Month15 and Month18(Month 3, Month 6, Month 9, Month 12, Month15 and Month18)
