SESSION TITLE: Obstructive Lung Diseases 3 SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/10/2018 01:00 PM - 02:00 PM PURPOSE: Elderly patients with chronic obstructive pulmonary disease (COPD) may be perceived to have increased difficulty using inhaled medications and decreased efficacy relative to younger patients with COPD. We investigated the consistency of the lung function benefit observed with the once daily inhaled corticosteroid/long acting beta2-agonist (ICS/LABA) fluticasone furoate/vilanterol (FF/VI) 100/25 delivered via the ELLIPTA dry powder inhaler in patients under or over 65 years of age relative to placebo or VI alone. METHODS: A preplanned analysis of the intent-to-treat (ITT) population <65 years and ≥65 years from two 24-week lung function trials (HZC112206, HZC112207) evaluated the two co-primary endpoints, weighted mean (WM) forced expiratory volume in 1 second (FEV1) 0-4 hours post-dose and trough FEV1, at the end of the studies. Subjects with COPD in these multicenter, double blind trials were randomized to treatment with FF/VI (200/25, 100/25, or 50/25 mcg), FF (200 or 100 mcg), VI 25 mcg, or placebo once daily via the ELLIPTA inhaler. Lung function was evaluated via spirometry at each study visit. Safety was evaluated by summaries of adverse events reported by age group. RESULTS: A total of 2254 subjects were randomized to treatment and received at least one dose, 1339 subjects <65 years (mean age=56) and 915 subjects ≥65 years (mean age=71). In each subgroup, improvements from baseline in lung function were observed in subjects treated with FF/VI 100/25 or VI compared with placebo. At day 168, WM FEV1 0-4 hours mean change from baseline for subjects <65 years treated with FF/VI 100/25, VI, and placebo was 220, 161, and 9 mL respectively; subjects ≥65 years demonstrated 177, 143, and 8 mL respectively. At day 169, trough FEV1 mean change from baseline for subjects <65 years treated with FF/VI 100/25, VI, and placebo was 173, 113, and 30 mL respectively; subjects ≥65 years demonstrated 116, 92, and 6 mL respectively. Subjects in both subgroups treated with FF/VI 100/25 had significant treatment differences from placebo (p≤0.002) at all time points assessed for each co-primary endpoint. The safety profile of each treatment group was similar and consistent between the age subgroups. CONCLUSIONS: In patients with COPD from both age subgroups, FF/VI 100/25 was well tolerated, provided numerical improvements in lung function compared with the LABA VI alone, and demonstrated consistently significant improvements in lung function compared with placebo throughout the study. CLINICAL IMPLICATIONS: These data provide evidence of consistent and clinically meaningful lung function response in patients treated with FF/VI 100/25 delivered via the ELLIPTA inhaler regardless of age.
