" SAVE Study (Switch AdVagraf® to Envarsus®) for Fast Metabolizers Kidney Transplant Recipients" (SAVE)
The use of calcineurin inhibitors (CNIs) in kidney transplantation is the gold standard treatment to prevent episodes of rejection. Nevertheless, CNIs have side effects and are in particular nephrotoxic for the kidney transplant. Monitoring CNI dosages is fundamental for the clinician, in order to find the right balance between toxicity and prevention of rejection. Several recent studies suggest that a Radio Residual Concentration / Dosage (C0 / D) less than 1.05 (patients with rapid metabolizers) is associated with poor graft function (eGFR) and decreased kidney transplant survival. LCPT prolonged-release tacrolimus (Novel Once-Daily Extended-Release Tacrolimus. Prolonged-release tacrolimus: Envarsus®) is a marketed form of tacrolimus with interesting pharmacokinetic properties: daily intake, reduction of the absorption peak (Meltodose® technology ) and reduction of the total CNI dose by 30% to obtain an equivalent CO compared to other molecules on the market (Advagraf®, Prograf®). Thus, the use of LCPT in patients rapid metabolisers in relay of Advagraf® or Prograf® could make it possible to decrease renal toxicity while preserving rejection, by increasing the C0 / D ratio.
The investigators propose a pilot study aiming to study a prospective cohort of rapid metabolisers patients put on Envarsus at one month of transplant compared to a historical cohort, in terms of C0 / D ratio, function and survival of the renal graft.
