- ItemOpen AccessComparison of vilanterol, a novel long-acting beta2 agonist, with placebo and a salmeterol reference arm in asthma uncontrolled by inhaled corticosteroids(BioMed Central, 2014-06-13) Lötvall, Jan; Bateman, Eric D; Busse, William W; O’Byrne, Paul M; Woodcock, Ashley; Toler, William T; Jacques, Loretta; Goldfrad, Caroline; Bleecker, Eugene RBackground: 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.

- ItemOpen AccessEfficacy and safety of fluticasone furoate 100 μg and 200 μg once daily in the treatment of moderate-severe asthma in adults and adolescents: a 24-week randomised study(BioMed Central, 2014-07-09) Woodcock, Ashley; Lötvall, Jan; Busse, William W; Bateman, Eric D; Stone, Sally; Ellsworth, Anna; Jacques, LorettaBackground: Inhaled corticosteroids are a mainstay of therapy for persistent asthma, but suboptimal adherence with twice-daily use is widespread. Fluticasone furoate (FF) is a new inhaled corticosteroid (ICS) suitable for once-daily dosing in asthma. This study was performed to descriptively assess the efficacy and safety of two doses of FF, with no planned formal statistical hypothesis testing. Methods: This was a 24-week double-blind, multicentre, parallel-group study (NCT01431950). Patients aged ≥ 12 years with moderate-severe persistent asthma and uncontrolled on mid-high dose ICS were stratified by baseline FEV1 and randomised (1:1) to treatment with FF 100 μg or 200 μg once daily in the evening. The primary endpoint was change from baseline trough FEV1 after 24 weeks; secondary and other endpoints included peak expiratory flow (PEF) and rescue-free and symptom-free 24-hour periods over Weeks 1–24, and Asthma Control Test™ (ACT) score at Week 24. A pre-specified subgroup analysis of patients by randomisation strata was performed for the primary and selected secondary and other endpoints. Safety assessments included adverse events, laboratory and vital sign measurements, and change from baseline in 24-hour urinary cortisol at Week 24. Results: With FF 100 μg and 200 μg, least squares mean trough FEV1 improved from baseline by 208 mL and 284 mL, respectively, at Week 24; treatment difference: 77 mL (95% CI: –39, 192). Similar improvements from baseline in rescue- and symptom-free periods, and morning and evening PEF were observed in both groups. Patients were 42% more likely to be well-controlled (ACT score ≥ 20) with FF 200 μg than with FF 100 μg. Slightly more patients receiving FF 200 μg vs. FF 100 μg reported adverse events (63% vs. 59%) and events deemed treatment related (5% vs. <1%). Seven serious adverse events (FF 200 μg 4; FF 100 μg 3) were reported, none of which were deemed treatment related. No clinically relevant effects of either dose on 24-hour urinary cortisol were observed. Conclusion: Improvements from baseline in trough FEV1 were observed after 24 weeks of treatment with both doses of FF, with a numerically greater improvement in FEV1 observed in patients receiving FF 200 μg. Secondary endpoint findings were similar between groups. No safety concerns were identified during the study.
- ItemOpen AccessEfficacy and safety of once-daily fluticasone furoate 50 mcg in adults with persistent asthma: a 12-week randomized trial(2014-08-11) O’Byrne, Paul M; Woodcock, Ashley; Bleecker, Eugene R; Bateman, Eric D; Lötvall, Jan; Forth, Richard; Medley, Hilary; Jacques, Loretta; Busse, William WAbstract Background Fluticasone furoate (FF) is a novel, once-daily inhaled corticosteroid (ICS) that has been shown to improve lung function vs. placebo in asthma patients. This study evaluated the efficacy and safety of FF 50 mcg compared with placebo in asthma patients uncontrolled by non-ICS therapy. Methods This 12-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, phase III study randomized 248 patients (aged ≥12 years) to once-daily FF 50 mcg administered via the ELLIPTA™a dry powder inhaler or placebo. The primary endpoint was change from baseline in pre-dose evening trough forced expiratory volume in one second (FEV1). Secondary endpoints were change from baseline in percentage of rescue-free 24-h periods (powered), evening and morning peak expiratory flow, symptom-free 24-h periods and withdrawals due to lack of efficacy. Other endpoints included Asthma Control Test™, Asthma Quality of Life Questionnaire and ELLIPTA ease of use questions. Safety was assessed throughout the study. Results There was a significant difference in evening trough FEV1 between FF 50 mcg and placebo (treatment difference: 120 mL; p = 0.012). There was also a significant difference in rescue-free 24-h periods (11.6%; p = 0.004) vs. placebo. There were numerically greater improvements with FF vs. placebo for all remaining secondary endpoints. The incidence of adverse events was lower with FF (31%) than with placebo (38%); few were treatment-related (FF 50 mcg: n = 1, <1%; placebo: n = 4, 3%). Conclusion FF 50 mcg once daily significantly improved FEV1 and percentage of rescue-free 24-h periods experienced over 12 weeks vs. placebo, and was well tolerated.

- ItemOpen AccessEfficacy in asthma of once-daily treatment with fluticasone furoate: a randomized, placebo-controlled trial(BioMed Central Ltd, 2011) Woodcock, Ashley; Bateman, Eric D; Busse, William W; Lotvall, Jan; Snowise, Neil G; Forth, Richard; Jacques, Loretta; Haumann, Brett; Bleecker, Eugene RBACKGROUND: Fluticasone furoate (FF) is a novel long-acting inhaled corticosteroid (ICS). This double-blind, placebo-controlled randomized study evaluated the efficacy and safety of FF 200 mcg or 400 mcg once daily, either in the morning or in the evening, and FF 200 mcg twice daily (morning and evening), for 8 weeks in patients with persistent asthma. METHODS: Asthma patients maintained on ICS for [greater than or equal to] 3 months with baseline morning forced expiratory volume in one second (FEV1) 50-80% of predicted normal value and FEV1 reversibility of [greater than or equal to] 12% and [greater than or equal to] 200 ml were eligible. The primary endpoint was mean change from baseline FEV1 at week 8 in pre-dose (morning or evening [depending on regimen], pre-rescue bronchodilator) FEV1. RESULTS: A total of 545 patients received one of five FF treatment groups and 101 patients received placebo (intent-to-treat population). Each of the five FF treatment groups produced a statistically significant improvement in pre-dose FEV1 compared with placebo (p < 0.05). FF 400 mcg once daily in the evening and FF 200 mcg twice daily produced similar placebo-adjusted improvements in evening pre-dose FEV1 at week 8 (240 ml vs. 235 ml). FF 400 mcg once daily in the morning, although effective, resulted in a smaller improvement in morning pre-dose FEV1 than FF 200 mcg twice daily at week 8 (315 ml vs. 202 ml). The incidence of oral candidiasis was low (0-4%) and UC excretion was comparable with placebo for all FF groups. CONCLUSIONS: FF at total daily doses of 200 mcg or 400 mcg was significantly more effective than placebo. FF 400 mcg once daily in the evening had similar efficacy to FF 200 mcg twice daily and all FF regimens had a safety tolerability profile generally similar to placebo. This indicates that inhaled FF is an effective and well tolerated once-daily treatment for mild-to-moderate asthma.TRIAL REGISTRATION:NCT00398645

- ItemOpen AccessFluticasone furoate: once-daily evening treatment versus twice-daily treatment in moderate asthma(BioMed Central Ltd, 2011) Woodcock, Ashley; Bleecker, Eugene R; Busse, William W; Lotvall, Jan; Snowise, Neil G; Frith, Lucy; Jacques, Loretta; Haumann, Brett; Bateman, Eric DBACKGROUND: Inhaled corticosteroids are the recommended first-line treatment for asthma but adherence to therapy is suboptimal. The objectives of this study were to compare the efficacy and safety of once-daily (OD) evening and twice-daily (BD) regimens of the novel inhaled corticosteroid fluticasone furoate (FF) in asthma patients. METHODS: Patients with moderate asthma (age [greater than or equal to] 12 years; pre-bronchodilator forced expiratory volume in 1 second (FEV1) 40-85% predicted; FEV1 reversibility of [greater than or equal to] 12% and [greater than or equal to] 200 ml) were randomized to FF or fluticasone propionate (FP) regimens in a double-blind, crossover study. Patients were not permitted to have used any ICS for [greater than or equal to] 8 weeks prior to enrolment and subsequently received doses of FF or FP 200 mug OD, FF or FP 100 mug BD and matching placebo by inhalation for 28 days each. Primary endpoint was Day 28 evening pre-dose (trough) FEV1; non-inferiority of FF 200 mug OD and FF 100 mug BD was assessed, as was superiority of all active treatment relative to placebo. Adverse events (AEs) and 24-hour urinary cortisol excretion were assessed. RESULTS: The intent-to-treat population comprised 147 (FF) and 43 (FP) patients. On Day 28, pre-dose FEV1 showed FF 200 mug OD to be non-inferior (pre-defined limit -110 ml) to FF 100 mug BD (mean treatment difference 11 ml; 95% CI: -35 to +56 ml); all FF and FP regimens were significantly superior to placebo (p [less than or equal to] 0.02). AEs were similar to placebo; no serious AEs were reported. Urinary cortisol excretion at Day 28 for FF was lower than placebo (ratios: 200 mug OD, 0.75; 100 mug BD, 0.84; p [less than or equal to] 0.02). CONCLUSIONS: FF 200 mug OD in the evening is an efficacious and well tolerated treatment for asthma patients and is not inferior to the same total BD dose.TRIAL REGISTRATION:Clinicaltrials.gov; NCT00766090.
