Benralizumab可减少重症哮喘患者口服激素的用量,但对患者肺功能改善无显著效果。

许多严重哮喘患者依靠口服糖皮质激素来控制疾病。近日研究人员考察了IL-5α亚基单克隆抗体benralizumab对哮喘急性加重发生率的控制效果以及能否减少患者口服糖皮质激素的剂量。

在为期28周的随机对照研究中,研究人员考察了benralizumab (皮下注射30 mg ,每4或8周 [前3剂每4周一次]) 或安慰剂对于重症哮喘患者的疾病控制以及激素减少效果。主要终点是28周口服激素量的变化,同时评价年哮喘发作率、肺功能、症状和安全性。

共220名患者参与研究,2个剂量的benralizumab可显著减少终点时激素的使用量,benralizumab组较基线减少75%,安慰剂组减少25%,benralizumab较安慰剂减少的激素剂量的比值比为4.0。次要终点分析中,相比于安慰剂,每4周的benralizumab可减少55%的哮喘发作率(0.83 vs 1.83, P=0.003),每8周的benralizumab可减少70%的哮喘发作率(0.54 vs 1.83, P<0.001)。28周时 benralizumab对患者一秒用力呼气量的改善效果不显著,对哮喘症状的改善存在较大差异性。Benralizumab与安慰剂不良事件发生率相近。

研究表明,Benralizumab可减少重症哮喘患者口服激素的用量,但对患者肺功能改善无显著效果。
