We show the ability of bortezomib to remove donor-specific HLA antibody from kidney allograft patients, the drug acting as a proteasome inhibitor, providing targeted therapy against antibody-producing plasma cells. Ten out of thirteen patients (77%) experienced primary DSA reversal, and in the remaining three patients the MFI of their primary DSA was dramatically reduced. Bortezomib is a viable therapy to treat donor-specific HLA antibody in allograft recipients. The potential for long-term benefits--and complications--are still unknown. Prospective trials are being conducted at the University of Cincinnati, Cincinnati, OH; at the Mayo Clinic, Rochester, MN; and at IKDRC-ITS, Ahmedabad, India.
