NCT03444103

Brief Summary

This bi-center study (Medical University of Vienna \& Charité Berlin) is an investigator-driven pilot trial designed to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy (preliminary assessment) of humanized anti-IL-6 monoclonal antibody clazakizumab in kidney transplant recipients with late antibody-mediated rejection (ABMR). The study is designed as a phase 2 trial and has two subsequent sub-parts, a randomized placebo-controlled trial (part A) of 12 weeks, where recipients are allocated to receive either anti-IL-6 antibody clazakizumab (n=10) or placebo (n=10), followed by an open-label prospective study, where all 20 study patients will receive clazakizumab for a period of 40 weeks. Study protocol biopsies will be performed at the end of part A and part B.
