Patients were randomized to receive UMEC/VI (62.5/25 A mu g once daily) via a multidose dry powder inhaler (ELLIPTA) followed by TIO/OLO (5/5 A mu g once daily) via a soft mist inhaler (Respimat), each for 8 weeks with an interim 3-week washout or vice versa. The primary end point was the change from baseline in trough FEV1 at week 8 with a noninferiority margin of - 50 mL in the per-protocol (PP) population. The incidence of adverse events was also assessed.In total, 236 patients (mean age 64.4 years, 60% male) were included in the intent-to-treat population and 227 were included in the PP population. UMEC/VI treatment was noninferior in the PP population and superior in the intent-to-treat population to TIO/OLO treatment with regard to trough FEV1 at week 8 [FEV1 change from baseline 180 mL vs 128 mL; difference 52 mL (95% confidence interval 28-77 mL); p %K Bronchodilation %K COPD %K LAMA %K LABA %K Long-acting muscarinic antagonist %K Long-acting beta 2-agonist %K Olodaterol %K Tiotropium %K Umeclidinium %K Vilanterol %K Dynamic hyperinflation %K Double-blind %K Copd %K Tiotropium %K Safety %K Bronchodilators %K Combination %K Moderate %~
