Long-acting beta-agonists (LABA) and long-acting muscarinic antagonists (LAMA) combination therapy improved lung function and health-related quality-of-life and reduced exacerbation rates and dyspnea in symptomatic chronic obstructive pulmonary disease (COPD) patients. We compared the real-world effects of three fixed-dose LABA/LAMA combinations for COPD in Taiwan. This multicenter, retrospective study evaluated 1-year outcomes after LABA/LAMA combination therapy in patients with symptomatic COPD. Exacerbations and symptoms of COPD, lung functions, and therapy escalation were compared among patients using tiotropium/olodaterol, umeclidinium/vilanterol and indacaterol/glycopyrronium. Propensity score matching (PSM) was applied to balance the baseline characteristics. Data of 1,617 patients were collected. After PSM, time to first moderate-to-severe COPD exacerbation was comparable among three groups, while the annualized rates of the exacerbation (episodes/patient/year) in patients receiving tiotropium/olodaterol (0.19) or umeclidinium/vilanterol (0.17) were significantly lower than those receiving indacaterol/glycopyrronium (0.38). COPD-related symptoms were stable over the treatment period, and there was no significant difference in the changes of symptom scores including CAT and mMRC among three groups at the end of the study period. This study presented valuable real-world outcome in terms of exacerbation and treatment response of COPD patients treated with fixed-dose LABA/LAMA regimens in Taiwan. The annualized rates of moderate-to-severe exacerbation in patients receiving tiotropium/olodaterol or umeclidinium/vilanterol were significantly lower than those receiving indacaterol/glycopyrronium, though the time to first moderate-to-severe exacerbation was similar among different fixed-dose LABA/LAMA combinations.
