Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Likelihood of finding a donor to whom the study participant does not have strong anti-donor HLA specific antibodies (DSA).	The likelihood of finding a suitable donor will calculated base on calculated Panel of Reactive Antibodies measured 1month after the therapy	1 year
Secondary	Strong Human Leukocyte Antigen (HLA) antibodies with mean fluorescence intensity (MFI) reduced by more than 50%	A number of strong HLA antibodies with MFI reduced by more than 50% will be counted	1 year
Secondary	Time to transplant	Time from the beginning of the implementation of the therapy to kidney transplantation will be measured	1 year
Secondary	Episodes of Antibody Mediated Rejection (AMR) and Acute Cellular Rejection (ACR)	Number of episodes of AMR and ACR after kidney transplantation will be counted	1 year
Secondary	Death	The incidence of episodes of patient death will be calculated	1 year
Secondary	Serious infection requiring inpatient intravenous therapies	Incidence rate of the episodes of serious infection requiring inpatient intravenous therapies will be calculated during the study	1 year
Secondary	Post-transplant lymphoproliferative disorder	The incidence rate of the episodes of post-transplant lymphoproliferative disorder will be calculated	1 year
