rATG Versus rATG Combined With Intravenous Immunoglobulin (IVIG) Induction Immunosuppression in HLA Incompatible Transplantation (INHIBIT)

There have been no published clinical studies evaluating rATG/IVIG induction protocol in comparison with rATG alone in defined cohort of HLA incompatible kidney transplant recipients. Prescribing IVIG in management of prevention of transplant rejection is considered off-label use, however IVIG remains part of induction protocols in many transplant centres. IVIG therapy is demanding due to high cost and limited resources of these human origin products. Trial participants will be end-stage renal disease (ESRD) patients listed for deceased donor / living donor kidney transplantation with anti HLA antibody screening performed within 12 months before transplantation and with last DSA 1 000 - 5 000 Mean Fluorescence Intensity (MFI) and negative CDC (Complement-dependent cytotoxicity crossmatch test) prior to transplantation. Participants will be randomized into one of the treatment groups (PE/PP(Plasmapheresis) + rATG + IVIG, PE/PP + rATG) and as a primary outcome a composite endpoint defined as occurrence of antibody- or T-cell mediated rejection within 12 months after transplantation will be evaluated.
