INTRODUCTION
· There is increasing interest in once-daily dosing for respiratory medications; current inhaled corticosteroid (ICS)/long-acting beta2 agonist (LABA) combinations require twice-daily dosing, which may result in lower adherence and greater COPD costs.(1)
· FF/VI is a novel combination ICS/LABA that has been assessed in COPD at various strengths in small-scale studies.(2),(3)
OBJECTIVES
· To compare the efficacy and safety of two mid-to-high strengths of FF/VI with its constituent components, FF and VI, and placebo in patients with moderate-to-severe COPD.
METHODS
· Multi-centre, randomised, stratified (smoking status), placebo-controlled, double-blind, parallel-group study.
· Patients: age >40 years; history of moderate-to-severe COPD; smoking history >10 pack-years; post-bronchodilator (postBD) forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio <0.70; postBD FEV1 <0.70 predicted; score of >2 on the Modified Medical Research Council Dyspnoea Scale (mMRC).
· Following a 2-week single-blind placebo run-in, patients were randomised in a 1:1:1:1:1:1 ratio to receive one of six treatments taken once daily in the morning via novel dry powder inhaler for 24 weeks: FF 100mcg, FF 200mcg, VI 25mcg, FF/VI 100/25mcg, FF/VI 200/25mcg, or placebo
· Salbutamol (as needed) and ipratropium bromide alone (stable dose) were permitted for symptom relief during run-in and treatment periods.
RESULTS
Study population and demographics
· Of 1909 patients screened, 1224 formed the intent-to-treat (ITT) population, 924 of whom completed the study.
· Patient characteristics at baseline are outlined in Table 1.
· Patient-reported medication use prior to screening: short-acting beta2-agonists 62%, short-acting anticholinergics 34%, LABA 35%, ICS 24%.

Efficacy: Co-Primary
· Weighted mean (wm; 0–4h post-dose, Day 168) and change from baseline in trough (23–24h post-dose, Day 169) FEV1 improved with all active therapies (Fig. 1a and b)
· wm and trough FEV1 significantly improved for VI 25mcg and FF/VI 200/25mcg vs. placebo; wm FEV1 significantly improved for FF/VI 200/25mcg vs. FF 200mcg; trough FEV1 was not significantly different for FF/VI 200/25mcg vs. VI 25mcg (Table 2)
· Significance for other comparisons could not be inferred due to the hierarchy employed in the statistical analysis.

Values are differences in least square mean (95% CI);
*significant difference (p<0.001). (a)Log rank analysis was used to analyse the secondary endpoint of time to 100mL improvement on Day 1. Inference from the associated p-values could not be drawn due to the testing hierarchy employed; b = for regulatory purposes in the USA, CRQ-SAS is considered an ‘other’ endpoint.
Efficacy: Secondary
· Chronic Respiratory Questionnaire Self-Administered Standardized (CRQ-SAS) dyspnoea domain scores improved numerically for all comparisons except FF (either strength) vs. placebo; no comparisons achieved minimally clinically important difference (Table 2).
· Peak FEV1 (0–4h) on Day 1 numerically improved for all comparisons except FF/VI 200/25 vs. VI 25 (Table 2).
· Median (actual) time to onset (increase of 100mL above baseline in FEV1) on Day 1 was 16–17 min in the FF/VI and VI treatment groups, 231 and 242 min in the FF 200 and 100 groups, respectively and not determinable in the placebo group.

Safety
· Incidence of adverse events AEs and serious AEs (SAEs), were similar with active therapy vs. placebo (Table 3).
· Pneumonia events were low, <2% of subjects in FF-containing arms, <1% with VI 25 and 0 with placebo. No events were fatal.
· 6 deaths were reported during the study; 5 on-treatment (1 each in the placebo, FF/VI 100/25 and 200/25 groups and 2 in the VI 25 group. None were considered treatment-related.
· Exacerbations occurred more frequently in the placebo arm (10%) vs. treatment arms (2–9%), and for VI (9%) vs. FF (2–5%).
· There were no clinically relevant abnormalities in clinical chemistry/haematology parameters, vital signs, 12-lead ECG and 24 h Holter monitoring.
· Assessment of 24 h urinary cortisol showed no clinically relevant or statistically significant effect of any treatment.

CONCLUSIONS
· The addition of the LABA VI to FF resulted in a rapid and sustained improvement in FEV1 in COPD patients with moderate-to-severe airflow obstruction.
· Once-daily FF/VI exhibited a tolerability profile that did not differ markedly from its individual components.
