Abstract
Introduction
COPD treatment guidelines recommend the use of a second bronchodilator when patients are not controlled on single bronchodilator therapy. QVA149 is a dual bronchodilator which combines indacaterol (IND; a long-acting β2-agonist) and glycopyrronium (GLY; a long-acting muscarinic antagonist) as a once-daily maintenance treatment for patients with COPD.
Methods
This summary of clinical efficacy includes data from 2667 patients from the QVA149 IGNITE clinical trial program. Endpoints presented here are lung function, COPD exacerbations, and safety.
Results
Improvements in all lung function parameters including trough, pre-dose and peak forced expiratory volume in 1 second (FEV1) with QVA149 were significantly greater (p<0.05) than placebo, IND, GLY, open-label tiotropium (TIO) and salmeterol/fluticasone (SFC) (Table). QVA149-treated patients had a significantly lower annualized rate of exacerbations compared to GLY and TIO (3.34 versus 3.92 and 3.89, respectively). Overall, QVA149 demonstrated a comparable safety profile to placebo, IND, GLY, TIO, and SFC.
Conclusions
Data from the IGNITE studies demonstrates that once-daily QVA149 provides clinically relevant benefits for patients with COPD as demonstrated by improved lung function and reduced exacerbations and has a favorable safety profile.
