BACKGROUND: Combinations of inhaled long-acting bronchodilator therapies such as muscarinic antagonists and β2-agonists may be more effective than monotherapy in the treatment of chronic obstructive pulmonary disease (COPD). METHODS: This study was a 24-week, Phase III, multicenter, randomized, blinded, double-dummy, parallel-group study of the once-daily, inhaled, fixed-dose combination of the long-acting muscarinic antagonist umeclidinium bromide and the long-acting β2-agonist vilanterol (UMEC/VI 62.5/25 mcg) versus tiotropium (TIO, 18 mcg). The primary endpoint was trough forced expiratory volume in 1 s (FEV1) at Day 169. The secondary endpoint was weighted mean FEV1 over 0–6 h post-dose at Day 168. For key endpoints, a step-down closed testing hierarchy was applied to account for multiplicity. Other efficacy and safety endpoints were assessed. RESULTS: Statistically significant improvements in trough FEV1 at Day 169 (0.112 L, 95% confidence interval [CI]: 0.081, 0.144; p < 0.001) and weighted mean FEV1 over 0–6 h post-dose at Day 168 (0.105 L, 95% CI: 0.071, 0.140; p < 0.001) were observed for UMEC/VI versus TIO. In addition UMEC/VI improved health-related quality of life, and reduced requirement for the use of rescue medication compared with TIO. The incidence of adverse events was similar between treatment groups. CONCLUSIONS: UMEC/VI was associated with statistically significant and clinically meaningful improvements in lung function versus TIO. UMEC/VI was well tolerated. UMEC/VI 62.5/25 mcg could provide an effective new treatment option for patients with moderate-to-very severe COPD.
