Summary

This randomized study addressed treatment of established antibody-mediated rejection after transplantation, not pretransplant desensitization. Thirty participants were randomized, and the trial was open label. Greater donor-specific antibody reduction with imlifidase did not establish clinical benefit; four graft losses occurred in the imlifidase arm and one in the plasma-exchange arm. These findings should not be pooled as direct evidence for the pretransplant indication.
