Brief Summary:
Graft nephrectomy is associated with massive allo-sensitization following this event. The occurrence of anti-HLA antibodies is a major barrier to perform a second kidney transplantation. Investigators 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 serious infectious complications following graft nephrectomy, with a treatment by Tocilizumab. Secondary endpoints evaluated here are - to evaluate all complications after graft nephrectomy, - and the Tocilizumab effectiveness to reduce anti-HLA antibodies at one year post nephrectomy.
Detailed Description:
Background: graft nephrectomy is associated with massive allo-sensitization following this event The occurrence of anti-HLA antibodies is a major barrier to perform a second kidney transplantation. Moreover, a systemic inflammatory response syndrome can occur which could lead to serious patient's complications, in case of early graft thrombosis. To date, no treatment or strategy is available to reduce these risks, after graft nephrectomy. IL-6 is a key cytokine in inflammation, but also in the development of T and B cells activation. This treatment previously demonstrated a major role in the occurrence of allo-antibodies. Tocilizumab is a monoclonal antibody blocking IL6 receptor, previously used with success in kidney transplantation to reduce anti-HLA antibodies mediated rejection.
Objectives: Investigators hypothesize that Tocilizumab is useful to prevent allo-sensitization post graft nephrectomy. They 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.
