Fluticasone furoate (FF)/vilanterol (100/25 mcg or 200/25 mcg) or FF (100 mcg) in persistent asthma.

OBJECTIVES: Fluticasone furoate (FF; inhaled corticosteroid) combined with vilanterol (VI; long-acting beta(2) agonist) is a once-daily therapy for asthma and chronic obstructive pulmonary disease. This 12-week phase III study compared the efficacy and safety of once-daily (evening dosing) FF/VI 100/25 mcg versus FF 100 mcg (primary objective) and FF/VI 100/25 mcg versus FF/VI 200/25 mcg (descriptive comparison only) in patients (n = 1039) ≥12 years with moderate-to-severe persistent asthma. METHODS: The primary end point was weighted mean (wm) 0-24-h serial forced expiratory volume in 1 s (FEV(1)) at week 12. Secondary end points (change from baseline) were trough FEV(1) and the proportion (%) of rescue-free 24-h periods (both powered), the proportion (%) of symptom-free 24-h periods, and morning and evening peak expiratory flow (PEF). Safety data (adverse events, AEs) were collected throughout. RESULTS: Compared with FF 100 mcg, FF/VI 100/25 mcg significantly improved wmFEV(1) (p < 0.001), trough FEV(1) (p = 0.014), % rescue-free (p < 0.001), % symptom-free (p = 0.002) 24-h periods, and morning and evening PEF (p < 0.001). FF/VI 200/25 mcg produced small numerical improvements versus FF/VI 100/25 mcg for all end points. Incidence of AEs was similar across groups. CONCLUSIONS: FF/VI 100/25 mcg resulted in significant improvements in all primary and secondary end points versus FF 100 mcg. Numerical improvements occurred with FF/VI 200/25 mcg versus FF/VI 100/25 mcg. All treatments were well tolerated.

Comparison of vilanterol, a novel long-acting beta2 agonist, with placebo and a salmeterol reference arm in asthma uncontrolled by inhaled corticosteroids.

BACKGROUND: Current maintenance therapies for asthma require twice-daily dosing. Vilanterol (VI) is a novel long-acting beta2 agonist, under development in combination with fluticasone furoate, a new inhaled corticosteroid (ICS). Findings from a previous 4-week study suggested that VI has inherent 24-hour activity and is therefore suitable for once-daily dosing. The study described here was a double-blind, double-dummy, randomised, placebo-controlled trial, the aim of which was to assess the efficacy of once-daily VI compared with placebo in patients with persistent asthma. The primary endpoint was change from baseline in 24-hour weighted mean forced expiratory volume in 1 second after 12 weeks of treatment vs. placebo. An active control arm received salmeterol (SAL) twice daily. All patients were maintained on a stable background dose of ICS. RESULTS: Patients (n = 347) received VI, placebo or SAL (1:1:1). For the primary endpoint, substantial improvements in lung function were seen with VI (359 ml), SAL (283 ml) and placebo (289 ml). There were no statistically significant treatment differences between either the VI (70 ml, P = 0.244) or SAL (-6 ml, P = 0.926) groups and placebo. Both active treatments were well tolerated, with similarly low rates of treatment-related adverse events compared with placebo. No treatment-related serious adverse events occurred. CONCLUSIONS: This study failed to show a treatment difference between VI and placebo for the primary endpoint, in the presence of a placebo response of unforeseen magnitude. Because the placebo response was so large, it is not possible to draw meaningful conclusions from the data. The reason for this magnitude of effect is unclear but it may reflect increased compliance with the anti-inflammatory therapy regimen during the treatment period.

Once-daily fluticasone furoate alone or combined with vilanterol in persistent asthma.

The inhaled corticosteroid fluticasone furoate (FF) and the long-acting ß2 agonist vilanterol (VI) are in development as a combined once-daily therapy for asthma and chronic obstructive pulmonary disease. Our study objectives were to compare the efficacy and safety of once-daily FF/VI with FF alone and twice-daily fluticasone propionate (FP) in patients aged ≥12 years with moderate-to-severe persistent asthma. Patients (n=586) received FF/VI 200/25 µg or FF 200 µg once-daily (evening dosing), or FP 500 µg twice-daily for 24 weeks. Co-primary end-points were change from baseline in trough forced expiratory volume in 1 s (FEV1) weighted mean (wm) 0-24 h serial FEV1. Secondary end-points included change from baseline in percentage of rescue-free 24-h periods, percentage of symptom-free 24-h periods and total Asthma Quality of Life Questionnaire (AQLQ). Safety assessments included adverse events, 24-h urinary cortisol excretion, vital signs and ECG. FF/VI significantly improved trough FEV1 and wmFEV1 versus FF and FP. Significantly more rescue-free and symptom-free 24-h periods were reported with FF/VI versus FF. Treatment differences for AQLQ were not significant. Incidence of adverse events was similar across groups. No clinically significant differences were seen for 24-h urinary cortisol excretion, vital signs or ECG. FF/VI resulted in statistically greater improvements in lung function and symptomatic end-points versus FF, and was well tolerated in this asthma population.

Fluticasone furoate nasal spray is more effective than fexofenadine for nighttime symptoms of seasonal allergy.

Nasal symptoms of allergic rhinitis are an important cause of sleep disturbance. Reduction of nasal symptoms, particularly nasal obstruction, has been linked to improvements in self-reported sleep quality. The enhanced-affinity intranasal corticosteroid fluticasone furoate and the oral antihistamine fexofenadine were compared with respect to nighttime symptoms of seasonal allergic rhinitis. In two randomized, double-blind, double-dummy, parallel-group studies, patients received fluticasone furoate nasal spray (FFNS),110 microg (study 1, n = 312; study 2, n = 224); fexofenadine, 180 mg (study 1, n = 311; study 2, n = 227); or placebo (study 1, n = 313; study 2, n = 229) once daily for 2 weeks. Fluticasone furoate was more effective (p < 0.001) than fexofenadine and placebo in both studies with respect to the mean changes from baseline over the treatment period in the nighttime symptoms score, nighttime reflective total nasal symptom score, predose instantaneous nasal symptom score, and morning peak nasal inspiratory flow. Fluticasone furoate was more effective than placebo (p
