Efficacy of Umeclidinium/Vilanterol in Elderly Patients with COPD: A Pooled Analysis of Randomized Controlled Trials.

The aim of this pooled analysis was to assess the efficacy and safety of umeclidinium/vilanterol (UMEC/VI) 62.5/25 µg dual bronchodilation versus placebo in elderly symptomatic patients with chronic obstructive pulmonary disease (COPD).We conducted a post hoc pooled analysis of data from 10 randomized controlled trials (RCTs). Change from baseline (CFB) in trough forced expiratory volume in 1 s (FEV), proportion of FEV responders (≥ 100-mL increase from baseline), and safety were analyzed in patients aged < 65, ≥ 65, and ≥ 75 years on Days 28, 56, and 84 (12-week analysis of parallel-group design studies), Days 28, 56, 84, 112, 140, 168, and 169 (24-week analysis of parallel-group design studies), and Days 2, 42, and 84 (12-week analysis of crossover design studies).The UMEC/VI intent-to-treat (ITT) populations comprised 2246, 1296, and 472 patients in the 12-week parallel-group, 24-week parallel-group, and 12-week crossover analysis, respectively (≥ 65 years: 36-44%; ≥ 75 years: 7-11%). The placebo ITT populations comprised 528, 280, and 505 patients, respectively (≥ 65 years: 37-41%; ≥ 75 years: 5-11%). Significant improvements in trough FEV and significantly greater proportions of FEV responders were seen with UMEC/VI compared with placebo in all analyses regardless of patient age or timepoint considered (p ≤ 0.023), except Day 84 trough FEV CFB in the 12-week crossover analysis in patients aged ≥ 75 years (p = 0.064). UMEC/VI safety profile was similar to placebo in all age groups.In this pooled analysis of RCT data, once-daily UMEC/VI was well tolerated and provided clinically significant lung function benefits compared with placebo in younger and older patients with COPD.GlaxoSmithKline (study 208125).
