Abstract
Introduction
The ILLUMINATE study evaluated the superiority of the once-daily QVA149 110/50µg, a dual bronchodilator combining the LABA indacaterol and the LAMA glycopyrronium, compared to twice-daily LABA/ICS, salmeterol/fluticasone 50/500µg (SFC), in terms of efficacy, safety and tolerability in patients (pts) with moderate-to-severe COPD. This analysis reports the efficacy and safety of QVA149 vs. SFC in the sub-group population using fixed-dose LABA/ICS prior to study enrollment.
Methods
122 pts on LABA/ICS prior to study entry were randomized to QVA149 (n=54) and SFC (n=68). FEV1 area under the curve for 0-12h (AUC0-12h), pre-dose trough FEV1, rescue medication use, exacerbations and safety were assessed after 26wks.
Results
QVA149 significantly improved FEV1 AUC0-12h, pre-dose trough FEV1 and reduced rescue medication use in COPD pts regardless of previous LABA/ICS use at study entry (Table). Number of exacerbations (QVA149: 23; SFC: 41) and pts with incidence of adverse events (QVA149: 50%; SFC: 55.9%) was numerically lower with QVA149.
Conclusion
In the subpopulation previously treated with LABA/ICS, QVA149 demonstrated significant improvements in lung function and rescue therapy use compared to SFC. These results were consistent with the overall study population.
