E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
the rate of serious infectious complication rate at 1 year post graft nephrectomy |
d’évaluer le taux de complications infectieuses graves suite à la néphrectomie dans la première année post geste dans une cohorte prospective de patients traités par Tocilizumab |
|
E.2.2 | Secondary objectives of the trial |
Complications other than infectious complications, Occurrence of allo-sensitization at one year post graft nephrectomy |
Les objectifs secondaires sont d'évaluer d'une part l'ensemble des complications post ablation du greffon, ainsi qu'une évaluation de l'efficacité du traitement pour réduire l'allo-immunisation à 1 an de la néphrectomie. |

E.5 End points |
E.5.1 | Primary end point(s) |
We hypothetize that Tocilizumab is usefull to prevent allo-sensitization post graft nephrectomy. We propose here to evaluate in a phase II pilot study, the safety of the use of a single dose of Tocilizumab immediately before or after graft nephrectomy. The primary endpoint evaluated here is the occurrence of infectious complications following early and late graft nephrectomy, with a treatment by Tocilizumab. |
l'objectif principal est d’évaluer le taux de complications infectieuses graves suite à la néphrectomie dans la première année post geste dans une cohorte prospective de patients traités par Tocilizumab |
