Once-daily fluticasone furoate/vilanterol vs once-daily fluticasone furoate in patients with asthma aged 5 to 17 years.

BACKGROUND: Limited data exist comparing inhaled corticosteroid (ICS) plus adjunctive therapy vs ICS alone in pediatric asthma patients. OBJECTIVE: To evaluate the efficacy and safety of fluticasone furoate/vilanterol (FF/VI) vs FF in children and adolescents with asthma. METHODS: This phase 3, randomized, double-blind, multicenter study (NCT03248128) included participants aged 5 to 17 years with six months or more asthma history uncontrolled on ICS monotherapy. Participants received 4-week open-label fluticasone propionate (100 µg) twice daily before 1:1 randomization to 24-week double-blind FF (50 µg:100 µg) or FF/VI (50/25 µg:100/25 µg) once daily. Two populations with different primary endpoints were analyzed to meet United States (week 12 weighted mean forced expiratory volume in 1 second [FEV1; 0-4 hours]; participants aged 5-17 years) and European (change from baseline predose morning peak expiratory flow [ΔAM PEF] averaged over weeks 1-12; participants aged 5-11 years) regulatory requirements. RESULTS: Overall, 902 participants, including 673 children aged 5 to 11 years, were randomized and treated. In participants aged 5 to 17, week 12 weighted mean FEV1 (0-4 hours) was greater with FF/VI vs FF (difference: 0.083 L; P < .001). In participants aged 5 to 11, ΔAM PEF over weeks 1 to 12 showed numerical improvement with FF/VI vs FF but was not statistically significant (difference: 3.2 L/min; P = .228). No drug-related serious adverse events or deaths were reported. CONCLUSION: FF/VI significantly improved weighted mean FEV1 (0-4 hours; participants aged 5-17 years), but not ΔAM PEF (participants aged 5-11 years) vs FF. No new safety concerns were apparent.

A multicenter randomized, double-blind, placebo-controlled, parallel-group study to evaluate the effects of a 1-year regimen of orally inhaled fluticasone furoate 50 µg once daily on growth velocity in prepubertal, pediatric participants with well-controlled asthma.

INTRODUCTION: Growth impairment is a known adverse event (AE) of corticosteroids in children. This study aimed to assess the effect of once-daily (QD) inhaled fluticasone furoate (FF) versus placebo on growth velocity over 1 year in prepubertal children with well-controlled asthma. MATERIALS AND METHODS: This randomized, double-blind, parallel-group, placebo-controlled, multicenter study (NCT02889809) included prepubertal children, aged 5 to <9 years (boys), and 5 to <8 years (girls), with ≥6 months' asthma history. Children received inhaled placebo QD plus background open-label montelukast QD for a 16-week run-in period and were then randomized 1:1 to receive inhaled FF 50 µg QD or placebo QD (whilst continuing background open-label montelukast) for a 52-week treatment period. The primary endpoint was the difference in growth velocity (cm/year) over the treatment period. Other growth endpoints were measured, as were incidence of AEs and asthma exacerbation. Growth analyses included all intent-to-treat (ITT) participants with ≥3 post-randomization, on-treatment clinic visit height assessments (GROWTH population). RESULTS: Of 644 children in the run-in period, 477 (mean age 6.2 years, 63% male) entered the 52-week treatment period (ITT population: FF N = 238, placebo N = 239; GROWTH population: N = 457 [FF N = 231; placebo N = 226]). The least-squares mean difference in growth velocity for FF versus placebo was -0.160 cm/year (95% confidence interval: -0.462, 0.142). There were no new safety signals. CONCLUSIONS: Over 1 year, FF 50 µg QD had a minimal effect on growth velocity versus placebo, with no new safety signals.

A randomized, double-blind, placebo-controlled, parallel-group study of once-daily inhaled fluticasone furoate on the hypothalamic-pituitary-adrenocortical axis of children with asthma.

BACKGROUND: To evaluate the effects of fluticasone furoate on the hypothalamic-pituitary-adrenocortical axis, and the safety and tolerability of fluticasone furoate treatment in children with asthma. METHODS: This was a randomized, double-blind, placebo-controlled, multicenter, stratified, parallel-group, non-inferiority study of fluticasone furoate 50 µg inhalation powder administered once daily. The study enrolled children (aged 5-11 years inclusive) with a documented diagnosis of asthma for ≥ 6 months and a Childhood Asthma Control Test score of > 19. After a 7-14-day run-in period, eligible subjects were stratified by age and randomized to fluticasone furoate 50 µg once daily or placebo once daily via ELLIPTA for 6 weeks. The primary endpoint was the change from baseline (expressed as a ratio) in 0-24-h weighted mean serum cortisol at the end of the treatment period. RESULTS: Fifty-six randomized subjects received fluticasone furoate 50 µg once daily and 55 received placebo. The primary analysis was performed in the serum cortisol population (n = 104) and demonstrated that fluticasone furoate 50 µg once daily was non-inferior to placebo (ratio = 0.93; 95% confidence interval 0.8096, 1.0620), as the lower limit of the 95% confidence interval for the geometric mean treatment ratio of fluticasone furoate 50 µg once daily versus placebo was greater than 0.80. Findings from the intent-to-treat population (n = 111) were similar. CONCLUSIONS: Six weeks of treatment with inhaled fluticasone furoate 50 µg once daily had no clinically relevant effect on the hypothalamic-pituitary-adrenocortical axis function of children, as measured by 24-h serum cortisol profiles. The primary analysis showed that fluticasone furoate 50 µg once daily was non-inferior to placebo. Fluticasone furoate 50 µg once daily was well tolerated and no new safety concerns emerged during the study. TRIAL REGISTRATION: This study is registered in ClinicalTrials.gov (NCT02483975).

A randomised open-label cross-over study of inhaler errors, preference and time to achieve correct inhaler use in patients with COPD or asthma: comparison of ELLIPTA with other inhaler devices.

Errors in the use of different inhalers were investigated in patients naive to the devices under investigation in a multicentre, single-visit, randomised, open-label, cross-over study. Patients with chronic obstructive pulmonary disease (COPD) or asthma were assigned to ELLIPTA vs DISKUS (Accuhaler), metered-dose inhaler (MDI) or Turbuhaler. Patients with COPD were also assigned to ELLIPTA vs Handihaler or Breezhaler. Patients demonstrated inhaler use after reading the patient information leaflet (PIL). A trained investigator assessed critical errors (i.e., those likely to result in the inhalation of significantly reduced, minimal or no medication). If the patient made errors, the investigator demonstrated the correct use of the inhaler, and the patient demonstrated inhaler use again. Fewer COPD patients made critical errors with ELLIPTA after reading the PIL vs: DISKUS, 9/171 (5%) vs 75/171 (44%); MDI, 10/80 (13%) vs 48/80 (60%); Turbuhaler, 8/100 (8%) vs 44/100 (44%); Handihaler, 17/118 (14%) vs 57/118 (48%); Breezhaler, 13/98 (13%) vs 45/98 (46%; all P<0.001). Most patients (57-70%) made no errors using ELLIPTA and did not require investigator instruction. Instruction was required for DISKUS (65%), MDI (85%), Turbuhaler (71%), Handihaler (62%) and Breezhaler (56%). Fewer asthma patients made critical errors with ELLIPTA after reading the PIL vs: DISKUS (3/70 (4%) vs 9/70 (13%), P=0.221); MDI (2/32 (6%) vs 8/32 (25%), P=0.074) and significantly fewer vs Turbuhaler (3/60 (5%) vs 20/60 (33%), P<0.001). More asthma and COPD patients preferred ELLIPTA over the other devices (all P⩽0.002). Significantly, fewer COPD patients using ELLIPTA made critical errors after reading the PIL vs other inhalers. More asthma and COPD patients preferred ELLIPTA over comparator inhalers.
