Randomized Controlled Trial Multicenter StudyEffects of indacaterol/glycopyrronium (QVA149) on lung hyperinflation and physical activity in patients with moderate to severe COPD: a randomised, placebo-controlled, crossover study (The MOVE Study).
Physical activity limitation is common in chronic obstructive pulmonary disease (COPD), and is associated with worse health status, and increased hospitalisation and mortality. Long-acting bronchodilators, either alone or in combination, have been shown to improve exercise intolerance. However, none of these studies were designed with physical activity as primary outcome. This study assessed the effect of indacaterol/glycopyrronium fixed dose combination (IND/GLY) 110/50 μg once daily (OD) versus placebo on lung hyperinflation (inspiratory capacity [IC]) and physical activity in patients with moderate-to-severe COPD. ⋯ In this study, compared with placebo, IND/GLY reduced hyperinflation, and, despite no patient education or lifestyle advice, improved daily physical activity levels. This suggests that IND/GLY has the potential to impact two of the main clinical concerns in the care of patients with COPD.
