Clinical Trial Summary

A multicenter observational study aiming to evaluate the efficacy of kallikrein inhibition by lanadelumab in patients with bradykinin- angioedema


Clinical Trial Description

The bradykinin-angioedema (AE-BK) is characterized by recurrent and unpredictable episodes of swelling; it can be disabling and disfiguring and the attacks affecting the larynx can be life-threatening. The clinical symptoms depend on accumulation of bradykinin (BK), a vasoactive peptide responsible for vasodilation and increase of vascular leakage. BK formation depends on activation of the kallikrein-kinin cascade leading to uncontrolled generation of plasma kallikrein and subsequent proteolysis of high molecular-weight kininogen (HK). Lanadelumab is a fully human monoclonal antibody inhibitor of plasma kallikrein, thereby preventing BK production; it represents an attractive therapeutic strategy for BK-AE prophylaxis. The aim of this study is to evaluate the kallikrein inhibition by assessing the levels of cleaved HK and the immunogenicity of the lanadelumab. ;
