Hereditary angioedema (HAE) is a rare, potentially life-threatening genetic disorder characterized by recurrent attacks of swelling. Local vasodilation and vascular leakage are stimulated by the vasoactive peptide bradykinin, which is excessively produced due to dysregulation of the activated factor XII (FXIIa)-driven kallikrein–kinin system. There is a need for novel treatments for HAE that provide greater efficacy, improved quality of life, minimal adverse effects, and reduced treatment burden over current first-line therapies. FXIIa is emerging as an attractive therapeutic target for interference with HAE attacks. In this review, we draw on preclinical, experimental animal, and in vitro studies, providing an overview on targeting FXIIa as the basis for pharmacologic interference in HAE. We highlight that there is a range of FXIIa inhibitors in development for different therapeutic areas. Of these, garadacimab, an FXIIa-targeted inhibitory monoclonal antibody, is the most advanced and has shown potential as a novel long-term prophylactic treatment for patients with HAE in clinical trials. The evidence from these trials is summarized and discussed, and we propose areas for future research where targeting FXIIa may have therapeutic potential beyond HAE.
遗传性血管性水肿(HAE)是一种罕见的、可能危及生命的遗传性疾病,其特征是反复发作的浮肿。由于活化因子 XII(FXIIa)驱动的缓激肽-激肽系统失调,导致缓激肽过度分泌,从而刺激局部血管扩张和血管渗漏。与目前的一线疗法相比,HAE 需要新型疗法,以提高疗效、改善生活质量、减少不良反应并减轻治疗负担。FXIIa 正在成为干扰 HAE 发作的一个有吸引力的治疗靶点。在这篇综述中,我们借鉴了临床前、实验动物和体外研究的结果,概述了以 FXIIa 为靶点作为药物干预 HAE 的基础。我们强调,目前有一系列针对不同治疗领域的 FXIIa 抑制剂正在开发中。其中,以 FXIIa 为靶点的抑制性单克隆抗体加拉达西单抗(garadacimab)是最先进的药物,在临床试验中已显示出作为一种新型长期预防性疗法治疗 HAE 患者的潜力。我们对这些试验的证据进行了总结和讨论,并提出了以 FXIIa 为靶点可能具有治疗 HAE 以外的潜力的未来研究领域。
