Desensitization With Bortezomib Before a Living Kidney Donation

Phase 4
Conditions
Patients Awaiting a Living Kidney Donation
Interventions
Registration Number
NCT01842074
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

The investigators plan to study the role of bortezomib for desensitizing patients awaiting a living kidney donation who have a titer of Donor Specific anti human leucocyte antigen (HLA) Antibody (DSA) between 1000 and 3000 MFI with a pilot study of 10 patients recruited in 4 hospital in FRANCE.

Detailed Description

The investigators plan to study the role of bortezomib for desensitizing patients awaiting a living kidney donation who have a titer of Donor Specific anti HLA Antibody (DSA) between 1000 and 3000 MFI with a multicentre pilot study of 10 patients. The effect of bortezomib will be observed up to 6 month after bortezomib treatment prior to transplantation and 12 month after transplantation if performed. The living kidney donation will be performed only if the DSA level drops below 1000 MFI which means an efficacy of the desensitization.

Primary Outcome Measures
NameTimeMethod
Proportion of patients with Donor specific antibody (DSA) level below 1000MFI authorizing the living kidney donationup 6 months after bortezomib treatment and before transplantation

Bortezomib treatment should allow a decrease in DSA level below a threshold level authorizing the living kidney donation with minimal risk
