PURPOSE: Umeclidinium (UMEC) is a long-acting muscarinic antagonist approved in the US and EU for maintenance treatment of chronic obstructive pulmonary disease (COPD). Fluticasone furoate/vilanterol (FF/VI; combination inhaled corticosteroid [ICS] + long-acting beta2 agonist [LABA]) is indicated for long-term, once-daily maintenance treatment of airflow obstruction in COPD. These two replicate studies evaluated efficacy and safety of UMEC added to FF/VI in patients with COPD.

METHODS: These were 12-week, randomized, double-blind, parallel-group studies (N=1238 [intent-to-treat population]). Eligible patients entered a 4-week run-in period on FF/VI (100/25 mcg; delivering 92 and 22 mcg, respectively) and were then randomized 1:1:1 to once-daily blinded UMEC 62.5 mcg (delivering 55 mcg), UMEC 125 mcg (delivering 113 mcg), or placebo (PBO) added to open-label FF/VI if they met randomization criteria. Primary endpoint was trough forced expiratory volume in one second (FEV1) on Day 85. Secondary endpoint was 0-6-hour post-dose weighted mean (WM) FEV1 on Day 84. Rescue use was also assessed. Safety endpoints included incidence of on-treatment adverse events (AEs) and AEs of special interest.

RESULTS: Compared with PBO+FF/VI, both doses of UMEC+FF/VI in both studies produced statistically significant and clinically meaningful improvements in trough FEV1 at Day 85 (range: 0.111-0.128 L, all p<0.001) and 0-6-hour WM FEV1 at Day 84 (range: 0.135-0.153 L, all p<0.001). Over Weeks 1-12, mean change from baseline in percentage rescue-free days was greater for UMEC 62.5+FF/VI (6.9-14.2%) and UMEC 125+FF/VI (5.9-8.7%) compared with PBO+FF/VI (2.3-3.8%). Reduction in puffs/day was significantly greater for UMEC 62.5+FF/VI compared with PBO+FF/VI (p≤0.003). Incidence of any on-treatment AEs were similar across all groups in both studies (30-39%). Fewer on-treatment cardiovascular AEs of special interest were reported with UMEC+FF/VI compared with PBO+FF/VI (≤1-2% vs 3%). Six deaths occurred (PBO+FF/VI [n=5]; UMEC 62.5+FF/VI [n=1]); none were considered related to study drug.

CONCLUSIONS: Once-daily UMEC (62.5 or 125 mcg) added to once-daily FF/VI resulted in improvements in lung function and rescue use compared with PBO+FF/VI in patients with COPD. Safety profiles were consistent across all treatment groups.

CLINICAL IMPLICATIONS: Triple combination therapy with UMEC+FF/VI is an effective treatment in patients with moderate-to-very-severe COPD. Studies were funded by GlaxoSmithKline (200109; NCT01957163; 200110; NCT02119286).
