简要总结
The purpose of this study was to determine whether potentiating the cystic fibrosis transmembrane conductance regulator (CFTR) with QBW251 in subjects with COPD would be efficacious with regards to reducing lung and systemic inflammation and bacterial colonization as potential drivers of airway obstruction, airway destruction, remodeling and exacerbations.
Furthermore, this study provided supportive data to investigate the relationship of COPD phenotype and the response in small airway structure, function, mucus load and spirometry indices as well as in improvement of overall COPD symptoms and quality of life.
详细描述
This was a randomized, subject and investigator blinded, parallel-group, placebo controlled study investigating the mode of action (MoA) and preliminary efficacy and safety of QBW251 administered orally twice daily (b.i.d.) for 12 weeks in subjects with moderate to severe COPD (GOLD 2-3).
The study consisted of the following periods: Screening, Baseline / Day 1, Treatment , and End of the Study followed by an additional post-treatment safety phone call. The total duration for each subject in the study is up to approximately 18 weeks.

结局指标
主要结局
Change From Baseline in Fibrinogen Plasma Concentrations After 12 Weeks of Treatment
时间窗: Baseline, week 12.
To assess the effect of QBW251 compared to placebo after 12 weeks of treatment on fibrinogen. The least-squares means for change from baseline in fibrinogen plasma concentrations after 12 weeks visits for each individual dose group were obtained from a linear mixed effects model for repeated measures (MMRM). A MMRM was fitted to the changes from baseline in fibrinogen for all time points until Day 84. A decrease in fibrinogen plasma concentration indicates improvement.
