INTRODUCTION

·                  It is recommended that for patients with asthma who remain symptomatic on inhaled corticosteroids (ICS)-only therapy, a long-acting beta2 agonist (LABA) is added.(1),(2)

·                  Combination ICS/LABA therapy can improve symptoms and achieve better asthma control, and in more patients, than ICS alone.(2)

·                  FF is a novel ICS in development as a once-daily treatment in combination with VI, a LABA with inherent 24-h activity, for asthma.

OBJECTIVES

·                  To compare the efficacy and safety of FF/VI 100/25mcg with FF 100mcg administered once daily in the evening for 12 weeks in patients >12 years with persistent asthma.

METHODS

·                  Phase III, multi-centre, randomised, double-blind, placebo-controlled, parallel group study.

·                  Patients: >12 years of age; asthma for >12 weeks prior to screening; maintained on stable low-mid dose ICS or low-dose ICS/LABA.

·                  Following 4-week run-in, patients were randomised (1:1:1) to receive one of the following for 12 weeks

·                  FF/VI 100/25mcg, FF 100mcg or placebo administered once daily in the evening via novel dry powder inhaler.

RESULTS

Study population and demographics (Table 1)

·                  Of 1110 patients screened, 610 were randomised and 609 received at least one dose of study medication (intent-to-treat [ITT] population) and 515 completed the study.

Trough FEV1 and serial (0–24h) wmFEV1 (Fig. 1)

·                  For trough FEV1 (pre-bronchodilator and pre-dose) at Week 12 (co-primary endpoint), statistically significant differences from placebo in change from baseline were seen for both FF/VI and FF

·                  difference compared with placebo: FF/VI 172mL (95% CI: 87, 258; p<0.001); FF 136mL (51, 222; p=0.002)

·                  the treatment difference between FF/VI and FF was not statistically significant: 36mL (–48, 120; p=0.405).

(a)  Screening values

·                  For serial (0–24h) weighted mean (wm) FEV1 at Week 12 (co-primary endpoint; subset of patients, n=309), statistically significant differences were seen for both FF/VI (302mL; 95% CI: 178, 426; p<0.001) and FF (186mL; 62, 310; p=0.003) vs. placebo

·                  the treatment difference between FF/VI and FF was not statistically significant (116mL; –5, 236; p=0.060)

·                  improvement in serial FEV1 at Week 12 was maintained over 24h with FF/VI and FF (Fig. 2).

Powered secondary

·                  An increase from baseline relative to placebo was seen in % rescue-free 24-h periods during the 12-week treatment period (powered secondary endpoint) with FF/VI and FF (treatment difference compared with placebo: FF/VI 19.3% [95% CI: 13.0, 25.6]; FF 8.7% [2.4, 15.0])

·                  a greater increase was seen with FF/VI than FF: 10.6% (4.3, 16.8).

Safety

·                  Overall incidence of on-treatment adverse events (AEs) was low (Table 2).

·                  One on-treatment serious AE (SAE) was reported (pancreatitis) by one patient on FF; this SAE was not considered treatment related.

·                  More patients had on-treatment severe asthma exacerbations on placebo (9, 4%) than FF/VI (1, <1%) or FF (4, 2%).

·                  Adjusted ratios relative to placebo for change from baseline in 24-h urinary cortisol excretion at Week 12 was 0.82 for FF/VI and 0.86 for FF.

Table 2. On-treatment AEs, treatment-related AEs and SAEs (ITT population)

(a)considered treatment-related; (b)one withdrawal was due to an AE of moderate skin rash and was considered treatment-related; (c)one SAE reported on-treatment (pancreatitis) and one post-treatment (appendicitis); (d)one SAE was reported pre-treatment (cystitis) and one post-treatment (moderate severity of prostate cancer)

CONCLUSIONS

·                  Significant improvement in lung function was observed with FF/VI 100/25mcg and FF 100mcg compared with placebo in patients with persistent asthma.

·                  Addition of VI to FF did not significantly improve FEV1, but a numerical increase was observed. The high placebo response in evening trough FEV1 may have influenced the interpretation of efficacy of the active therapies in this study.
