Background: The FLAME study demonstrated that indacaterol/glycopyrronium (IND/GLY), the fixed-dose combination of a long-acting β2-agonist (LABA, IND) and a long-acting muscarinic antagonist (LAMA, GLY), was superior to salmeterol/fluticasone combination (SFC) in preventing exacerbations in COPD patients with a high risk of exacerbations. In this study, we report a prespecified analysis of the efficacy and safety of IND/GLY versus SFC in Asian patients from the FLAME study. Patients and methods: Patients from Asian centers with moderate-to-very severe COPD and ≥1 exacerbation in the previous year from the 52-week, randomized FLAME study were included. IND/GLY was compared versus SFC for effects on exacerbations, lung function (forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC]), health status (St George’s Respiratory Questionnaire [SGRQ]), rescue medication use, and safety. Results: A total of 510 Asian patients (IND/GLY, n=250 or SFC, n=260) were included. Compared to the overall FLAME population, the Asian cohort had more males, a shorter duration of COPD, fewer patients using inhaled corticosteroid (ICS) at screening, fewer current smokers, and more patients with very severe COPD. IND/GLY significantly reduced the rate of moderate/severe exacerbations (rate ratio: 0.75; 95% confidence interval: 0.58–0.97; P=0.027) and prolonged time to first moderate/severe exacerbation versus SFC (hazard ratio: 0.77; 95% confidence interval: 0.59–1.01; P=0.055). Predose trough FEV1 and FVC significantly improved in Asian patients (P<0.001). IND/GLY improved SGRQ for COPD (SGRQ-C score; P=0.006) and reduced rescue medication use (P=0.058) at week 52. Pneumonia incidence was 3.6% with IND/GLY and 7.7% with SFC (P=0.046). Conclusion: In exacerbating Asian COPD patients, IND/GLY was more effective than SFC.
