Safety & Tolerability of Berinert® (C1 Inhibitor) Therapy to Prevent Rejection

Completed · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Kidney Transplantation

In brief

Organ transplantation offers the only hope for a normal life for patients with end-stage renal disease on dialysis (ESRD). For the highly-sensitized patient, patients with antibodies to human leukocyte antigens (HLA), transplantation is extremely difficult or impossible since pre-formed antibodies will cause severe rejection and loss of transplanted organs. Approximately 30% of the transplant list in the U.S. is considered sensitized (have detectable antibodies to HLA antigens). These anti-HLA (anti-Human Leukocyte Antigen antibodies) pose a significant barrier to transplantation that has recently been successfully addressed using desensitization therapies with IVIG, rituximab and/or plasmapheresis (PE). Despite the success of these therapies, post-transplant antibody mediated rejection (AMR) and chronic Antibody Mediated Rejection (CAMR) remain significant problems. Recent data suggests that addition of Berinert (C1 Inhibitor) to post-transplant treatment regimen may significantly reduce incidence of Antibody Mediation Rejection. Twenty highly-sensitized patients who have undergone desensitization treatment and are awaiting kidney transplant will be enrolled in the study. Once transplanted these patients will be started on the standard of care post-transplant immunosuppressive protocol. In addition patients will receive Berinert 20 units/ kg daily x 3 days, then twice weekly x 3 weeks. At the end of Berinert treatment a kidney biopsy will be performed. Subjects will be followed for 6 months to assess safety and efficacy of the study protocol.
