QVA149为新型的复合型支气管舒张剂,1吸的剂量为茚达特罗110μg/格隆溴铵50μg。早前的研究发现,应用QVA149治疗COPD后,与单用茚达特罗和安慰剂相比,患者的气道舒张更为持久且耐受性良好。为了进一步证实联合用药的优越性,来自南非开普敦大学临床医学部的Bateman博士等人进行了一项研究。该研究结果发表于2013年12月的《欧洲呼吸杂志》(Eur Respir J)上。研究人员发现,联

QVA149为新型的复合型支气管舒张剂,1吸的剂量为茚达特罗110μg/格隆溴铵50μg。早前的研究发现,应用QVA149治疗COPD后,与单用茚达特罗和安慰剂相比,患者的气道舒张更为持久且耐受性良好。为了进一步证实联合用药的优越性,来自南非开普敦大学临床医学部的Bateman博士等人进行了一项研究。该研究结果发表于2013年12月的《欧洲呼吸杂志》(Eur Respir J)上。研究人员发现,联合应用LABA/LAMA治疗中-重度COPD优于单药治疗。【原文下载

该研究是为期26周的多中心、随机、双盲、安慰剂-活性药物对照研究。所有入选的中-重度COPD患者在筛选期后,以2:2:2:2:1的比例,随机进入QVA149组(茚达特罗110μg/格隆溴铵50μg),茚达特罗组(茚达特罗150μg),格隆溴铵组(格隆溴铵50μg),噻托溴铵组(噻托溴铵18μg)。所有药物用量均为每日1吸。

在用药第1-2天,第2、4、8、12、16、20和26周检测肺功能。采用短暂呼吸困难指数(TDI)和圣乔治呼吸问卷(SGRQ)对患者呼吸困难和健康状况进行评估。采用心电图、血常规、血生化和尿常规等检测药物的安全性。

该研究主要研究指标为,第26周时,各药物治疗组的第一秒用力呼气容积谷值(trough FEV1)。次要研究指标为第26周时QVA149组和安慰剂组的短暂呼吸困难指数、圣乔治呼吸问卷和每日急救药物用量。第一秒用力呼气容积谷值定义为用药后23小时15分钟和23小时45分钟的FEV1平均值。
共2144例中-重度COPD患者参与其中。研究结果表明,在第26周时,与单用茚达特罗组、格隆溴铵组、噻托溴铵组和安慰剂组相比,QVA149组的第一秒用力呼气容积谷值显著改善。

与安慰剂组和噻托溴铵组相比,QVA149组的呼吸困难和健康状态也改善明显。所有治疗药物均耐受性良好。


各试验组不同时间点FEV1的改变

该研究首次证实固定剂量的LABA/LAMA(QVA149)联合治疗中-重度COPD患者优于支气管舒张药物单药治疗,且具有良好的安全性和耐受性。
