ABSTRACT
Purpose:
Previous studies demonstrating efficacy and safety of once-daily umeclidinium (UMEC) in patients with chronic obstructive pulmonary disease (COPD) have included few Asian patients. This study evaluated efficacy and safety of UMEC 62.5 mcg versus placebo in Asian patients with COPD. Patients andMethods:
A Phase III, randomized, double-blind, parallel-group study. Patients (aged ≥40 years with COPD, pre-, and post-albuterol forced expiratory volume in 1 s [FEV1]/forced vital capacity ratio <0.70 and low risk of exacerbations) were randomized 21 to once-daily UMEC 62.5 mcg or placebo via the ELLIPTA inhaler for 24 weeks. Primary endpoint was change from baseline (CFB) in trough FEV1 on Day 169. Secondary endpoints were weighted mean FEV1 over 0-6 hrs post-dose on Day 1 and CFB in Transition Dyspnea Index (TDI) focal score on Day 168.Results:
A total of 306 patients were included in the modified intent-to-treat population (UMEC 205; placebo 101). UMEC versus placebo provided a statistically significant improvement in least squares (LS) mean trough FEV1 between baseline and Day 169 (154 mL [95% confidence interval (CI) 113, 194]; p<0.001). A clinically meaningful difference of 125 mL in favor of UMEC (95% CI 103, 147; p<0.001) was also seen in LS weighted mean FEV1 0-6 hrs post-dose on Day 1. A LS mean treatment difference in TDI focal score of 0.9 units in favor of UMEC was seen on Day 168 (95% CI 0.3, 1.5; p=0.004). Incidence of on-treatment adverse events (AEs) was lower in the placebo (55%) versus UMEC arm (60%); non-fatal serious AEs, drug-related AEs, and AEs leading to withdrawal were similar with UMEC and placebo.Conclusion:
Once-daily UMEC 62.5 mcg resulted in statistically significant and clinically meaningful improvements in lung function and dyspnea, compared with placebo, in Asian patients with COPD, with no new safety concerns observed.Palavras-chave
