SESSION TITLE: COPD QVA149 Posters

PURPOSE: Patients with severe COPD experience marked deterioration in lung function and breathlessness compared to patients with mild-to-moderate COPD. We report improvement of dyspnea and lung function in patients with severe COPD in the BLAZE study with QVA149, a dual bronchodilator combining the long-acting β2-agonist (LABA) indacaterol and the long-acting muscarinic antagonist (LAMA) glycopyrronium (NVA237), versus placebo and tiotropium.

METHODS: In this 6-week, multicenter, blinded, placebo-controlled, 3-period, crossover study, patients aged ≥40 years with moderate-to-severe COPD were randomized to QVA149 110/50µg or tiotropium 18 µg or placebo. Improvements in patient-reported dyspnea via the innovative self-administered computerized (SAC) Baseline and Transition Dyspnea Index (BDI/TDI) and FEV1 AUC0-4h were assessed.

RESULTS: 78 (31.6%) of the 247 patients randomized had severe COPD. The percentage of patients with severe COPD achieving ≥1 point improvement in SAC-TDI total score was higher with QVA149 (41.7%) compared with tiotropium (30.0%; odds ratio 1.66; p=0.185) and placebo (21.7%; odds ratio 2.98; p=0.007). QVA149 provided rapid bronchodilation, with statistically significant (p<0.001) improvements in FEV1 AUC0-4h versus placebo and tiotropium. Least squares mean treatment difference between QVA149- placebo and QVA149- tiotropium were 1.92 (p<0.001) and 0.76 (p=0.042) for SAC-TDI and 254mL and 92mL (both p<0.001) for FEV1 AUC0-4h, respectively.

CONCLUSIONS: In patients with severe COPD, once-daily QVA149 provided clinically meaningful and statistically superior improvements in lung function which translated into better control of breathlessness compared to placebo and standard tiotropium.

CLINICAL IMPLICATIONS: Improved lung function with LABA/LAMA combination, QVA149, translates into greater relief of breathlessness and improved patient-reported outcomes.
