Exploring the relevance and extent of small airways dysfunction in asthma (ATLANTIS): baseline data from a prospective cohort study

2019

BACKGROUND: Small airways dysfunction (SAD) is well recognised in asthma, yet its role in the severity and control of asthma is unclear. This study aimed to assess which combination of biomarkers, physiological tests, and imaging markers best measure the presence and extent of SAD in patients with asthma.METHODS: In this baseline assessment of a multinational prospective cohort study (the Assessment of Small Airways Involvement in Asthma [ATLANTIS] study), we recruited participants with and without asthma (defined as Global Initiative for Asthma severity stages 1-5) from general practices, the databases of chest physicians, and advertisements at 29 centres across nine countries (Brazil, Chi…

Once-daily QVA149 improves dyspnoea and health status compared with tiotropium plus formoterol in patients without ICS use: A post-hoc analysis of th…

2015

Rationale: The QUANTIFY study compared the approved dual bronchodilator QVA149 with the free-dose combination of tiotropium plus formoterol (TIO+FOR) regarding lung function, dyspnoea and health status in patients with moderate-to-severe COPD. This post-hoc analysis reported on the subgroup of pts without ICS background therapy. Methods: This blinded, triple-dummy 26-week study randomised patients to QVA149 110/50 µg OD or TIO 18 µg OD plus FOR 12 µg b.i.d. (1:1). ICS was allowed as background therapy. Endpoints included lung function (trough FEV1), dyspnoea (TDI) and health status (COPD Assessment Test, CAT). Results: Of the 934 pts randomised (QVA149 [N=476] or TIO+FOR [N=458]); 87.9% com…

Efficacy and safety of once-daily QVA149 compared with the free combination of once-daily tiotropium plus twice-daily formoterol in patients with mod…

2015

Background QVA149 is a once-daily (o.d.) inhaled dual bronchodilator containing a fixed-dose combination of the long-acting β2-agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium for the treatment of COPD. The QUANTIFY study compared QVA149 with a free-dose bronchodilator combination of tiotropium plus formoterol (TIO+FOR) in improving health-related quality of life (HRQoL) of patients with COPD. Methods This multicentre, blinded, triple-dummy, parallel-group, non-inferiority study randomised patients aged ≥40 years with moderate-to-severe COPD (post-bronchodilator forced expiratory volume in 1 s (FEV1) ≥30% to <80% predicted) to QVA149 110/50 µg o.d. or TIO 18 µg o…
