Clazakizumab for Chronic and Active Antibody Mediated Rejection Post-Kidney Transplant

Summary

Antibody mediated rejection (ABMR) is a unique, significant and often severe form of allograft rejection. This single center, phase I/II, open label single-arm exploratory study focuses on enrolling ten patients with biopsy proven chronic antibody medicated rejection and/or donor specific antibody present at time of biopsy. Patients who qualify will be receiving clazakizumab (anti-IL6 monoclonal antibody) monthly x six doses. A protocol biopsy will be performed at 6 months and if improvement is seen, patients will continue another six doses for up to 12 months. For those completing 12 doses, there will be a 12 month protocol biopsy. For those who only received six doses, the next and last study visit will be at 12 months from enrollment. Total study duration is 12 months.
