ABSTRACT Fluticasone furoate (FF) is an inhaled corticosteroid (ICS) with 24-hour activity in development as a once-daily treatment for the long-term management of asthma.
To assess the efficacy and safety of 4 doses of once-daily FF administered using a dry powder inhaler in patients (≥12 years) with moderate asthma, uncontrolled on low-dose ICS (fluticasone propionate [FP] 200 μg/day or equivalent).
This double-blind, placebo-controlled, dose-ranging study randomized 622 patients to 1 of 6 treatments: FF (100, 200, 300, or 400 μg) once daily in the evening, FP 250 μg twice daily (active control), or placebo for 8 weeks. The primary endpoint was the change from baseline in predose evening forced expiratory colume in 1 second (FEV(1)) at week 8.
At week 8, relative to placebo, all doses of FF once daily and FP twice daily demonstrated significantly (P < .001) greater increases from baseline and greater than 200-mL increases in predose FEV(1). There was no evidence of a dose-response relationship between FF doses. Improvement with once-daily FF was similar to or greater than that for twice-daily FP. Secondary efficacy endpoint findings generally supported the efficacy of FF 100 to 400 μg once daily, although statistically significant improvements versus placebo in symptom-free 24-hour periods were only reported for FF 400 μg. There were few withdrawals due to lack of efficacy. Oral candidiasis was reported in 0 to 4% of patients; 24-hour urinary cortisol excretion ratios were similar across active treatment groups and not significantly different from placebo.
FF 100 to 400 μg once daily in the evening is effective and well tolerated in patients with asthma uncontrolled on low-dose ICS, with 100 μg and 200 μg, considered the most applicable doses in this asthma population.

    ABSTRACT: Inhaled corticosteroids (ICSs) improve asthma disease control; once-daily ICS administration may have advantages for patients. Our objective was to assess the efficacy and safety of the novel ICS fluticasone furoate (FF) over 24 weeks versus placebo. This was a 24-week double-blind, double-dummy, placebo- and active-controlled study (NCT01159912) of 343 asthma patients (≥12 years) not controlled by their current ICS. Patients were randomised (1:1:1) to FF100 μg, placebo (both administered once-daily [OD] via ELLIPTA™ dry powder inhaler in the evening) or fluticasone propionate (FP) 250 μg (administered twice-daily (BD) via DISKUS™/ACCUHALER™). Primary endpoint was change from baseline in pre-dose evening forced expiratory volume in 1s (FEV1) at Week 24; change from baseline in % rescue-free 24-h periods was a powered secondary endpoint. Adverse events (AEs) were assessed. FF100 μg OD and FP250 μg BD significantly improved pre-dose evening FEV1 compared with placebo at Week 24 (+146 ml [p = 0.009] and +145 ml [p = 0.011], respectively). Percentage of rescue-free 24-h periods was increased with FF100 μg OD (+14.8%) and FP250 μg BD (+17.9%) compared to placebo (both p < 0.001). On-treatment AEs were reported by 53% (FF100 μg OD), 42% (FP250 μg BD) and 40% (placebo) of patients. On-treatment severe asthma exacerbations were lower with FF100 μg OD (3%) and FP250 μg BD (2%) than placebo (7%). There was significant suppression of urinary cortisol at week 24 with FF100 μg OD (p = 0.030) and FP250 μg BD (p = 0.036) relative to placebo. FF100 μg OD, administered in the evening, achieves significant improvements in lung function and rescue inhaler use over 24 weeks, comparable to FP250 μg BD with similar safety profile.

    ABSTRACT: A combination of fluticasone furoate (FF) and umeclidinium (UMEC) has been considered for development for the treatment of asthma. The primary objectives were to investigate the plasma and urine pharmacokinetics (PK) of FF/UMEC in combination compared with FF and UMEC monotherapies. This randomized, double-blind, three-period crossover, single-center study in healthy volunteers assessed the PK of FF 400 mcg and UMEC 500 mcg administered separately and in combination (four inhalations of FF/UMEC 100/125 mcg, FF 100 mcg, or UMEC 125 mcg) via dual-strip dry powder inhaler. Subjects were randomized based on codes generated using a validated computerized system (Randall, GlaxoSmithKline). Eighteen subjects were enrolled; 17 received all three scheduled doses of study medication. Plasma FF and UMEC concentrations peaked at 0.5 and 0.08 h post-dose, respectively, for FF/UMEC and the monotherapies. FF and UMEC co-administration resulted in slightly lower or similar systemic exposure for both drugs versus the monotherapies. In post hoc sensitivity analyses (performed because two subjects administered inhalations incorrectly), the ratio of adjusted geometric means (maximum plasma concentration and area under the curve) was closer to unity than in the planned analyses. Cumulative urinary UMEC excretion (Ae) was similar for FF/UMEC and UMEC. Post hoc sensitivity analyses on Ae0-24 suggested a small carryover effect but results were similar to those of the population as a whole. Urinary UMEC excretion following FF/UMEC was low (~1.5% over 24 h) and unlikely to have impacted upon PK comparisons. Three adverse events were reported; none were severe or led to withdrawal. There were no clinically significant effects on electrocardiogram, vital sign, or laboratory parameters. Fluticasone furoate and umeclidinium co-administration was well tolerated and was not associated with meaningful changes in systemic or urinary PK versus the monotherapies. GlaxoSmithKline.

    ABSTRACT: Fluticasone furoate/vilanterol (Relvar®) is a once-daily, fixed combination of an inhaled corticosteroid (ICS) and a long-acting β2-adrenoreceptor agonist (LABA), delivered via a dry powder inhaler (Ellipta®). It is approved for the treatment of asthma in the EU and Japan, and is the first once-daily ICS/LABA to be available for this indication. Fluticasone furoate is an enhanced-affinity glucocorticoid receptor agonist, with potent anti-inflammatory activity. Vilanterol produces rapid and prolonged bronchodilation. In phase III trials in adolescents and adults with various levels of asthma uncontrolled on ICS and/or ICS/LABA, fluticasone furoate/vilanterol 100/25 or 200/25 µg once daily (approved dosages in the EU) significantly improved pulmonary function compared with placebo or equivalent dosages of fluticasone furoate alone (in some trials) or fluticasone propionate. In similar trials, fluticasone furoate/vilanterol 100/25 µg once daily was as effective as fluticasone propionate/salmeterol 250/50 µg twice daily in improving pulmonary function and significantly reduced the risk of severe asthma exacerbation relative to fluticasone furoate alone. In clinical trials, fluticasone furoate/vilanterol was generally well tolerated with fewer than 15 % of patients experiencing treatment-related adverse events, the most common of which were oral/oropharyngeal candidiasis, dysphonia, extrasystoles and cough. The tolerability profile of fluticasone furoate/vilanterol was generally similar to that of fluticasone propionate/salmeterol. Thus, fluticasone furoate/vilanterol is an effective and generally well tolerated ICS/LABA option for the treatment of uncontrolled asthma.
