荷兰阿姆斯特丹UMC血管内科Erik S.G. Stroes团队研究了前激肽释放酶反义抑制控制遗传性血管水肿的疗效。2020年9月24日,该研究发表在《新英格兰医学杂志》上。

遗传性血管性水肿的特征是反复发作且无法预测的皮下和粘膜肿胀,有可能危及生命。IONIS-PKK-LRx是配体偶联的反义寡核苷酸,被研究人员设计用于受体介导的肝细胞递送。

在一项同情用药的先导研究中,研究组招募了两名患有严重缓激肽介导的血管性水肿的患者,最初每周一次皮下注射未结合的母体药物IONIS-PKKRx,持续12至16周。之后每3至4周以80 mg的剂量接受IONIS-PKK-LRx,持续7至8个月。

在治疗的过程中,血管性水肿的发作率显著降低。

Abstract: SummaryHereditary angioedema is characterized by recurrent and unpredictable episodes of subcutaneous and mucosal swelling that can be life threatening. IONIS-PKK-LRx is a ligand-conjugated antisense oligonucleotide designed for receptor-mediated delivery to hepatocytes. In a compassionate-use pilot study, two patients with severe bradykinin-mediated angioedema were initially administered weekly subcutaneous injections of the unconjugated parent drug, IONIS-PKKRx, for 12 to 16 weeks, after which they received IONIS-PKK-LRx at a dose of 80 mg every 3 to 4 weeks for 7 to 8 months. Treatment was accompanied by a reduction in the angioedema attack rate.
