title: Efficacy and safety of once-daily QVA149 compared with twice-daily salmeterol-fluticasone in patients with chronic obstructive pulmonary disease (ILLUMINATE): a randomised, double-blind, parallel group study.
abstract: BACKGROUND
  QVA149 is an inhaled fixed-dose combination therapy under development for the treatment of chronic obstructive pulmonary disease (COPD). It combines indacaterol (a longacting β2-agonist) with glycopyrronium (a longacting muscarinic antagonist) as a dual bronchodilator. We aimed to compare the efficacy, safety, and tolerability of QVA149 versus salmeterol-fluticasone (SFC) over 26 weeks in patients with moderate-to-severe COPD.
  
  
  METHODS
  In this multicentre double-blind, double-dummy, parallel-group study, 523 patients (age 40 years or older, Global Initiative for Chronic Obstructive Lung Disease [GOLD] stages II-III, without exacerbations in the previous year) were randomly assigned (1:1; via automated, interactive response technology and stratified for smoking status) to once-daily QVA149 110/50 μg or twice-daily SFC 50/500 μg for 26 weeks. Efficacy was assessed in the full analysis set (randomised patients who received at least one dose of study drug); safety was assessed in all patients who received at least one dose of study drug. The primary endpoint was to demonstrate the superiority of QVA149 compared with SFC for the standardised area under the curve from 0 to 12 h post dose for forced expiratory volume in 1 second (FEV1 AUC0-12h) after 26 weeks of treatment. This trial was registered at ClinicalTrial.gov, NCT01315249.
  
  
  RESULTS
  Between March 25, 2011, and March 12, 2012, 259 patients were randomly assigned to receive QVA149 and 264 to receive SFC. At week 26, FEV1 AUC0-12h was significantly higher with QVA149 than with SFC (treatment difference 0·138 L; 95% CI 0·100-0·176; p<0·0001). Overall incidence of adverse events (including COPD exacerbations) was 55·4% (143 of 258) for the QVA149 group and 60·2% (159 of 264) for the SFC group. Incidence of serious adverse events was similar between treatment groups (QVA149, 13 of 258 [5·0%]; SFC 14 of 264 [5·3%]); COPD worsening was the most frequent serious adverse event (one of 13 [0·4%] and three of 14 [1·1%], respectively).
  
  
  CONCLUSIONS
  Once-daily QVA149 provides significant, sustained, and clinically meaningful improvements in lung function versus twice-daily SFC, with significant symptomatic benefit. These results indicate the potential of dual bronchodilation as a treatment option for non-exacerbating symptomatic COPD patients.
