NEJM:Dupilumab治疗中重度不受控制哮喘的疗效显著

2018-05-22 zhangfan MedSci原创

研究认为,Dupilumab可降低哮喘患者恶化率,改善肺功能和哮喘症状,特别对于嗜酸性粒细胞基线水平较高人群的疗效更为显著

Dupilumab是一种全人抗白细胞介素4受体α单克隆抗体,可以同时抑制白介素4和13信号通路。近日研究人员考察了Dupilumab对不受控制哮喘患者的疗效。

研究招募了1902名12岁以上不受控制的哮喘患者,随机接受200mg、300mg的 Dupilumab或安慰剂治疗,每2周一次,持续52周。研究的主要终点是严重哮喘恶化率以及12周后一秒用力呼气量(FEV1)变化,次要终点为每立方毫米嗜酸性粒细胞计数300或以上患者的哮喘恶化率及FEV1变化。

200mg Dupilumab组患者年度哮喘恶化率为0.46,而安慰剂组为0.87,Dupilumab治疗可降低47.7%的哮喘恶化风险。300mg组的治疗效果相近。12周后,200mg治疗组患者的FEV1增加0.32L,安慰剂组为0.14L,300mg组患者呼气增加更为显著。对于血嗜酸性粒细胞计数300及以上患者,200mg治疗组患者年度哮喘恶化率为0.37,对照组为1.08,风险降低65.8%。治疗最常见的不良事件为嗜酸性粒细胞增加(4.1% vs 0.6%)。

研究认为,Dupilumab可降低哮喘患者恶化率,改善肺功能和哮喘症状,特别对于嗜酸性粒细胞基线水平较高人群的疗效更为显著。
