Novel Desensitization Protocol With Proteasome Inhibitor and Costimulation Blockade for Highly Sensitized Patients to Allow for Successful Kidney Transplantation. A Pilot Study.

Description

This proposal's objective is to determine whether belatacept, in conjunction with a proteasome inhibitor can be used to safely increase the likelihood of finding an acceptable donor for highly HLA sensitized kidney transplant candidates.This is a pilot study to test the safety and effectiveness of the desensitization therapy with belatacept and proteasome inhibitor to increase the likelihood of of finding an acceptable donor for highly HLA sensitized kidney transplant candidates.
