Once-daily fluticasone furoate 50 mcg in mild-to-moderate asthma: a 24-week placebo-controlled randomized trial.

BACKGROUND: Inhaled glucocorticosteroids (ICS) are the mainstay of treatment in asthma. Fluticasone furoate (FF) is a novel, once-daily ICS asthma therapy. This study investigated the efficacy and safety of FF 50 mcg in patients with mild-to-moderate persistent asthma. METHODS: A 24-week, multicenter, randomized, placebo-controlled and active-controlled, double-blind, double-dummy, parallel-group phase III study. Three hundred and fifty-one patients (aged ≥12 years; uncontrolled by non-ICS therapy) were randomized to treatment (1 : 1 : 1) with once-daily FF 50 mcg dosed in the evening, twice-daily fluticasone propionate (FP) 100 mcg or placebo. The primary endpoint was change from baseline in evening trough forced expiratory volume in 1 s (FEV1 ) at Week 24. Secondary endpoints were change from baseline in the percentage of rescue-free 24-h periods (powered endpoint), change from baseline in evening and morning peak expiratory flow, change from baseline in the percentage of symptom-free 24-h periods and number of withdrawals due to lack of efficacy. RESULTS: Evening trough FEV1 at Week 24 was not statistically significantly increased with FF 50 mcg once-daily (37 ml [95% CI: -55, 128]; P = 0.430), but was with FP 100 mcg twice daily (102 ml [10, 194]; P = 0.030), vs placebo. No consistent trends were observed across other endpoints, including the powered secondary endpoint. No safety concerns were raised for either active treatment. CONCLUSIONS: FP 100 mcg twice daily improved evening trough FEV1 in patients with mild-to-moderate persistent asthma, but FF 50 mcg once daily did not demonstrate a significant effect. Secondary endpoints showed variable results. No safety concerns were identified for FF or FP.

Effects of 2 inhaled corticosteroids on growth: results of a randomized controlled trial.

OBJECTIVE: To compare the long-term effect of treatment with fluticasone propionate or beclomethasone dipropionate on growth in asthmatic children. DESIGN: Prospective, multicenter, randomized, double-blind, parallel-group study. SETTING: Children requiring regular treatment with inhaled corticosteroids and with a sexual maturity rating of Tanner stage 1 (prepubertal). PATIENTS: Three hundred forty-three children aged 4 to 11 years with asthma. The growth population (excluding patients with protocol violations likely to affect growth measurements) included 277 patients. INTERVENTIONS: Fluticasone propionate or beclomethasone dipropionate, both at a dosage of 200 microg administered twice daily via a dry powder inhaler (Diskhaler) for 12 months. MAIN OUTCOME MEASURES: Growth velocity, lung function, and serum and urinary cortisol levels. RESULTS: The adjusted mean growth velocity in the fluticasone group was significantly greater than that in the beclomethasone group (5.01 [SE, 0.14] vs 4.10 [SE, 0.15] cm/y; difference, 0.91 cm; 95% confidence interval, 0.63-1.20 cm; P<.001). Both treatments improved lung function, with significant differences in favor of fluticasone. Adverse events were similar in both groups, and there were no significant differences in effect on serum and urinary cortisol levels. CONCLUSIONS: The more favorable risk-benefit ratio of fluticasone indicates that this agent is preferable to beclomethasone for the long-term treatment of children with asthma, especially if moderate doses are required.

Fluticasone propionate 50 micrograms BID versus 100 micrograms BID in the treatment of children with persistent asthma. Fluticasone Propionate Study Group.

The aim of this multicenter, double-masked study was to compare the efficacy and safety of two different doses of inhaled fluticasone propionate dry powder--50 micrograms and 100 micrograms--administered BID via a multidose powder inhaler with those of placebo in the treatment of children with persistent asthma. After a 2-week run-in period, 263 patients were randomized to treatment with twice-daily placebo (n = 92), fluticasone 50 micrograms (n = 85), or fluticasone 100 micrograms (n = 86) for 12 weeks. One hundred sixty-six (63%) patients were male, and 224 (85%) were white, with a mean age of 8 years. Two hundred twenty-one (84%) patients were atopic, and 167 (63%) had been asthmatic for 1 to 5 years. Baseline mean morning peak expiratory flow (PEF) values were 207 L/min, 199 L/min, and 194 L/min, and baseline percentages of predicted normal values were 86%, 80%, and 81% for the groups receiving placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. At the end of the first week of treatment, patients in both fluticasone groups had significantly greater improvements in morning PEF than did those receiving placebo. Patients experienced mean increases of 4 L/min, 22 L/min, and 26 L/min with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. At the end point (the last evaluable visit), patients in both fluticasone groups continued to have significantly greater improvements in morning PEF than did patients receiving placebo. Patients experienced mean increases of 17 L/min, 50 L/min, and 57 L/min with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. Changes in the percentage of predicted values by end point were 8%, 20%, and 26% with placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. The probability of remaining in the study, according to predefined withdrawal criteria, indicated a significant treatment difference in favor of fluticasone. Withdrawal criteria were met by 63%, 42%, and 29% of patients receiving placebo, fluticasone 50 micrograms, and fluticasone 100 micrograms, respectively. This study clearly demonstrates the superiority of fluticasone 50 and 100 micrograms BID over placebo in the treatment of persistent asthma in children.

Fluticasone propionate in asthma: a long term dose comparison study.

BACKGROUND: Few dose ranging studies have investigated optimal dosing with inhaled corticosteroids in children with asthma. AIMS: To compare the efficacy and tolerability of fluticasone propionate 100 or 200 microg twice daily in children with moderate to severe asthma for one year. METHODS: One year, randomised, double blind, parallel group, multicentre study. Children aged 4-11 years (n = 528) with moderate to severe asthma who had previously received high dose inhaled corticosteroids were given fluticasone propionate 100 or 200 microg twice daily for the 52 week treatment period. Efficacy (exacerbations, lung function, and symptoms) and tolerability (adverse events and cortisol levels) were measured. RESULTS: There was a non-significant decreased risk of experiencing an exacerbation at any time with fluticasone propionate 200 microg twice daily compared with fluticasone propionate 100 microg twice daily. This difference reached significance among patients with more severe asthma (defined by previous inhaled corticosteroid dose >800 microg/day). Daily record card morning peak expiratory flow (PEF) in the total population improved significantly more with the higher dose of fluticasone propionate (between group difference, weeks 1-52: 11.4 l/min). Clinic visit mean PEF improved from baseline with both doses, but the response was significantly greater with the higher dose (between group difference, week 52: 17.8 l/min). Both doses were equally well tolerated and overnight urinary cortisol concentrations were unchanged or slightly increased during treatment with either dose. CONCLUSION: This long term dose comparison study shows that treatment with fluticasone propionate 200 micro g twice daily may offer benefits over a lower dose, particularly in children with more severe asthma.
