Abstract:

Objective    To investigate the efficacy and safety of fluticasone propionate(FP) inhalation solution compared with oral prednisone(PRE) in Chinese pediatric and adolescent subjects(aged 4 to 16 years) with an acute exacerbation of asthma. Methods    This was a randomized, double-blind, double-dummy, active-controlled, parallel-group, multi-center,non-inferiority study involving subjects(aged 4 to 16 years old,inclusive) with an acute exacerbation of asthma[to compare the morning Peak expiratory flow(AM PEF). Oral PRE once daily 2 mg/(kg·d),up to 40 mg/d for 4 d,then 1 mg/(kg·d) or half of the original dose,up to 20 mg/d for 3 d) for 7 d. The study comprised a 7-d treatment period and a 14-d follow-up period]. Results    In terms of the primary efficacy endpoint mean AM PEF,the low limit of 95% CI was -9.64 L/min,which was above the pre-defined non-inferiority margin -12 L/min.  Conclusion FP inhalation solution was shown to be non-inferior to oral PRE in the treatment of acute exacerbation of asthma in Chinese pediatric and adolescent patients. FP inhalation solution demonstrates good safety.

摘要:

目的 观察比较4~16岁哮喘患儿急性发作期雾化吸入丙酸氟替卡松(FP)吸入溶液与口服泼尼松(PRE)的安全性和有效性。方法 根据随机、双盲、双模拟、活性药物对照、平行分组、多中心等研究设计要求,于2012年12月至2016年6月,将11家医院收集到的261例4~16岁哮喘急性发作受试者随机分为2组。观察组
130例给予雾化吸入FP 1 mg,每日2次;对照组131例给予口服PRE,每日1次[前4 d为2 mg/(kg·d),最多40 mg/d;后3 d为1 mg/(kg·d)或予1/2初始剂量,最多20 mg/d],治疗7 d,对比两组的肺功能等指标。结果 平均最大呼气流量(PEF)在两组之间差异的95% 可信区间下限为-9.64 L/min,大于事先规定的非劣效界值-12 L/min。在次要评估终点各项指标中FP组和PRE组差异无统计学意义。FP组发生的不良事件少于PRE组。结论 雾化吸入FP对哮喘患儿急性发作期的疗效不差于口服PRE,且具有良好的安全性。
