Eur Respir J:贝那利珠单抗与白细胞介素-5抑制剂治疗重症哮喘的间接比较

2018-12-01 xing.T MedSci原创

由此可见,MAIC是间接比较来自异质患者群体试验的治疗功效的有力方法。当基线患者特征在哮喘试验中匹配时,贝那利珠单抗和美泊珠单抗产生了相似的疗效。

贝那利珠单抗是一种针对白细胞介素-5受体α亚基的单克隆抗体,可直接消耗嗜酸性粒细胞。对于严重且不受控制的哮喘患者,其相对于其他IL-5靶向治疗的相对疗效尚未完全明确。

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究文章,研究人员对贝那利珠单抗与美泊珠单抗和瑞利珠单抗进行了匹配调整的间接比较(MAIC)。通过系统评价和评估试验方法来选择试验。在间接疗效比较之前,对接受贝那利珠单抗治疗的患者数据进行加权以匹配比较试验中治疗效果调整的患者特征。

匹配调整后,贝那利珠单抗和美泊珠单抗与安慰剂相比分别使病情加重减少了52%和49%(比率[RR]为0.94,95%CI为0.78-1.13; n=1524),并使需要住院/急诊科就诊的急性发作分别减少了52%和52%(RR为1.00,95%CI为0.57-1.75; n=1524)。贝那利珠单抗和美泊珠单抗治疗32周时支气管扩张前1s内用力呼气量改善情况类似(差异为0.03L,95%CI为-0.06至0.12; n=1443)。贝那利珠单抗和瑞利珠单抗治疗的患者群体不太相似,无法得到足够的有效样本量,无法对MAIC进行可靠的估计。

由此可见,MAIC是间接比较来自异质患者群体试验的治疗功效的有力方法。当基线患者特征在哮喘试验中匹配时,贝那利珠单抗和美泊珠单抗产生了相似的疗效。
