[Translation] A Double-Blind, Multicenter, Randomized, Three-Period, Three-Treatment, Crossover Study to Evaluate the Effects of BGF MDI, BFF MDI, and Placebo MDI on Motor Parameters in Participants with COPD (ATHLOS)
本研究的主要目的是研究布地奈德、格隆溴铵和富马酸福莫特罗(BGF)定量吸入器(MDI)与安慰剂MDI相比以及BGF MDI与布地奈德和富马酸福莫特罗(BFF)MDI相比对等时IC的影响。布地奈德、格隆溴铵和富马酸福莫特罗MDI可减少动态过度充气并提高IC,从而改善COPD参与者的运动耐量。
本研究的次要目的是研究BGF MDI与安慰剂MDI相比以及随后的BFF MDI对运动耐受时间的影响。通过恒定功率测试(CWT)评估的运动耐受时间被认为是对COPD治疗干预应答的一项有价值的评估。
[Translation] The primary objective of this study was to investigate the effects of budesonide, glycopyrrolate, and formoterol fumarate (BGF) metered dose inhaler (MDI) compared with placebo MDI and BGF MDI compared with budesonide and formoterol fumarate (BFF) MDI on isochronic IC. Budesonide, glycopyrrolate, and formoterol fumarate MDI may reduce dynamic hyperinflation and increase IC, thereby improving exercise tolerance in COPD participants.
The secondary objective of this study was to investigate the effects of BGF MDI compared with placebo MDI and subsequently BFF MDI on exercise tolerance time. Exercise tolerance time, assessed by constant power test (CWT), is considered a valuable assessment of response to therapeutic interventions in COPD.
