INTRODUCTION
· For asthma patients symptomatic despite ICS therapy, a long-acting beta2 agonist (LABA) may be added.(1),(2)
· Current ICS/LABA combinations for asthma such as FP/SAL are administered twice daily; once-daily dosing of ICS/LABA may improve symptom control by improving patient adherence.
· The combination of FF (an ICS) and VI (a LABA) is in development as a once-daily therapy for asthma.
OBJECTIVES
· To compare the efficacy of FF/VI 100/25mcg administered once daily in the evening with FP/SAL 250/50mcg administered twice daily (morning and evening) over a 24-week treatment period in patients >12 years of age with persistent asthma.
METHODS
· Phase III, multi-centre, randomised, double-blind, double-dummy, parallel group study.
· Eligible patients: aged >12 years; >12% and >200mL reversibility of FEV1 with salbutamol; evening pre-bronchodilator FEV1 40–85% pred; documented use of ICS for >12 weeks with stable ICS dose (FP 250mcg twice daily or equivalent) for >4 weeks.
· After 4-week run-in on FP 250mcg twice daily, patients were randomised to 24 weeks’ treatment with
· FF/VI 100/25mcg once daily (evening dosing) via novel dry power inhaler
· FP/SAL 250/50mcg twice daily via DISKUSTM/ACCUHALERTM.
RESULTS
Study population and demographics (Table 1)
· Of 1564 patients screened, 806 were randomised (intent-to-treat [ITT] population) and 715 completed the study.
Efficacy
· Clinically important improvements from baseline in 0–24h serial weighted mean (wm) FEV1 after 24 weeks (primary endpoint) were seen with both FF/VI (341mL) and FP/SAL (377mL)
· the adjusted mean treatment difference was not statistically significant (–37mL [95% CI: –88, 15], p=0.162; Fig. 1).

LS=least squares; CI=confidence interval
· No statistically significant differences were reported between FF/VI and FP/SAL for serial wmFEV1 (0–4h) and clinic visit trough FEV1 (secondary endpoints).
· A greater number of patients receiving FF/VI vs. FP/SAL had an improvement of >0.5 points (minimally important difference)(3) from baseline in their Total Asthma Quality of Life Questionnaire (+12) score (‘other’ endpoint; post-hoc analysis) at Week 24 (46% vs. 38%).
Safety
· Incidences of on-treatment adverse events (AEs), treatment-related AEs and serious AEs (SAEs) were similar between treatments (Table 2)
· no SAEs were considered treatment-related
· no deaths were reported during the study.
· No clinically relevant differences between FF/VI and FP/SAL were reported for 24-h urinary cortisol (UC) excretion (adjusted treatment ratio 0.85 [95% CI: 0.72, 1.02], p=0.075) (Fig. 2) or vital signs.

CONCLUSIONS
· There was no difference between once-daily FF/VI and twice-daily FP/SAL in improving lung function in patients with persistent asthma.
· FF/VI improved quality of life (post-hoc analysis) compared with FP/SAL.
· No safety issues were identified with either treatment.
