De Novo Everolimus Versus Tacrolimus in Combination With Mofetil Mycophenolate and Low Dose Corticosteroids to Reduce Tacrolimus Induced Nephrotoxicity in Liver Transplantation: a Prospective, Multicentric, Randomised Study

Registration Number
NCT02909335
Lead Sponsor
Rennes University Hospital
Brief Summary

Tacrolimus is a calcineurin inhibitor. This is the immunosuppression of reference for patients undergoing a first liver transplant. This treatment can prevent graft rejection, but can cause side effects including kidney failure (in 25% after the first year).

Everolimus is an immunosuppressive that effectively prevents acute rejection in heart and kidney transplant recipients. It preserves renal function when it is started soon after the transplant, i.e. before a severe dysfunction is installed.

Detailed Description

In the liver transplant, early interruption of calcineurin inhibitors with a quick relay everolimus monotherapy preserves renal function and is associated with a lower acute rejection rate.

We wish to assess whether the introduction of a de novo immunosuppression everolimus under protection of basiliximab induction, mycophenolate mofetil and then low doses of corticosteroids, reduces the nephrotoxicity of immunosuppressive therapy in liver transplant patients, compared to a standard protocol with tacrolimus associated with mycophenolate mofetil and low dose corticosteroids.

Primary Outcome Measures
NameTimeMethod
Occurrence of graft lossBetween the baseline and the end of the treatment (week 48) (censored criterion

Graft loss , whatever the cause, or thrombosis of the hepatic artery are recorded between baseline and the end of S48 (censored criterion).

Worsening of renal functionBetween the initiation of treatment (Day 5) and the end (week 48) (censored criterion)

The main objective of the study is to evaluate, in liver transplanted patients, the benefit in terms of prevention of renal failure, a regimen that includes a de novo introduction of everolimus instead of tacrolimus, in combination with mycophenolate mofetil and low doses of corticosteroids, to the extent that this benefit is not accompanied by an increased risk of graft loss or hepatic artery thrombosis.

Insofar as the objective of the study is to assess a risk / benefit ratio, the study has two main criteria.

Worsening renal function is validated before the prolonged decline (found on at least 3 assays carried out at least 3 months apart) over 30% of the creatinine clearance compared to the value at baseline . The date of the first evidence of this worsening of renal function is the date used to calculate the distribution of censored criterion.
