  Purpose

The main objective of this study is to demonstrate that the absence of post-transplantation corticosteroids does not induce a larger increase of renal graft fibrosis (by numerical reading) on biopsy at one year post-transplantation than immunosuppressive treatment strategy that includes standard oral corticosteroids.The secondary objectives of the study consist to compare on various parameters (fibrosis progression, renal function, dialysis, ratio of proteinuria/creatinuria, acute rejection, donor-specific antibody, graft survival, clinical and biological tolerance) therapy with no corticosteroids post-transplantation in comparison to standard immunosuppressive treatment strategies including oral corticosteroids. Secondary objectives of the study consist also to compare the two techniques for assessing fibrosis by numerical reading and by centralized blinded reading of the treatment group (by 2 anatomical pathologists).

Primary Outcome Measures:
  • Percentage of fibrosis of the graft [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    Evolution of the percentage of fibrosis of the graft during the first year after transplantation (pre-transplant biopsy versus biopsy at one year), by numerical reading of fibrosis by image analysis.


Secondary Outcome Measures:
  • Percentage of fibrosis of the graft [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    Evolution of the percentage of fibrosis of the graft during the first year after transplantation (pre-transplant biopsy versus biopsy at one year of which the blinded readings to treatment group are made by two independent anatomical pathologists, the Banff criteria 2009).

  • Percentage of fibrosis of the graft. [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The percentage of fibrosis of the graft at one year post-transplantation (biopsy at one year with numerical reading of fibrosis by image analysis and blinded reading to treatment group by two independent anatomical pathologists, the Banff criteria 2009).

  • Average glomerular filtration rate [ Designated as safety issue: No ]
    The average glomerular filtration rate, calculated by the MDRD formula (four variables, Modification Diet in Renal Disease).

  • Dialysis session [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The percentage of patients with at least one dialysis session realised during the first year of transplant.

  • Ratio of proteinuria/creatinuria [ Designated as safety issue: No ]
    Average of ratio of proteinuria/creatininuria (mg / mmol).

  • Episode of acute rejection [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The percentage of patients with at least one episode of acute rejection during the first year after transplantation. We will distinguish biopsy-proven acute rejection (RABP), the corticosteroids resistant RABP and severe RABP (Banff 2009).

  • Diagnosis of DSA [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The percentage of patients with a diagnosis of DSA (Luminex® method) at 3 months and 1 year post-transplantation.

  • Percentage of graft failure [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The percentage of graft failure (death or return to dialysis) during the first year of transplantation (the short duration of the study avoids the management of right censoring).

  • Difference between numerical reading of fibrosis and evaluation by anatomical pathologists [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    The difference between the percentage of graft fibrosis evaluated by numerical reading of fibrosis and that assessed by two independent anatomical pathologists (Banff 2009 criteria) at baseline, 3 months and 1 year post-transplantation.

  • Number of adverse events [ Time Frame: One year post-transplantation ] [ Designated as safety issue: No ]
    Adverse events (AE) at 12 months post-transplantation, of which AEs of special interest (NODAT, dyslipidemia, hypertension, CMV viral infections, BKV) with an assessment of vital signs, physical examinations and laboratory tests.
