Efficacy and Safety of Once Daily Fluticasone Furoate Nasal Spray for Treatment of Irritant (Non-allergic) Rhinitis.

INTRODUCTION: The safety and efficacy of fluticasone furoate nasal spray (FFNS) for the symptoms of seasonal and perennial allergic rhinitis have been previously demonstrated in several clinical studies. The objective of this pilot study was to compare the efficacy and safety of FFNS 110 mcg once daily with placebo in patients with irritant (non-allergic) rhinitis triggered predominantly by air pollution. METHODS: This was a randomized, double-blind, placebo-controlled, 4-week study of subjects in Thailand with irritant rhinitis who received either FFNS 110 mcg (N=53) or placebo (N=49) once-daily. Subjects with a ≥2 year history of air pollution as their predominant rhinitis trigger, negative skin test to local seasonal/perennial allergens, positive histamine skin test, and normal sinus radiograph were enrolled if they met minimum reflective total nasal symptom score (rTNSS) ≥4.5 (maximum=9) and a nasal congestion score of ≥2 (maximum =3). All were assessed for nasal eosinophilia at study entry and completion. Air quality was monitored throughout the study. The primary efficacy endpoint was the mean change from baseline over the treatment period in daily rTNSS, the average of the morning and evening rTNSS. The key secondary measure was the mean change from baseline over the entire treatment period in morning pre-dose instantaneous total nasal symptom score (iTNSS). RESULTS: The Air Quality Index (AQI) during the study generally did not reach unhealthy levels. Baseline daily rTNSS scores were similar between treatment groups (FFNS=6.7; placebo=6.4). The least square mean change from baseline in rTNSS was -2.17 and -2.10 for FFNS and placebo, respectively, with a difference of -0.065 (p=0.845). Gradual improvements were seen in both treatment groups for iTNSS; however, the treatment difference (-0.075) was not statistically significant (p=0.827). Additionally, there were no statistically significant differences between treatment groups for AM and PM rTNSS, individual nasal symptoms, daily reflective, AM and PM reflective and AM pre-dose instantaneous total ocular symptom scores (TOSS) or individual ocular symptom scores. Nasal cytology at baseline found more than two-thirds of subjects had <20% eosinophils. Adverse events were few and similar between groups and noted as mild in intensity. CONCLUSION: Subjects receiving FFNS had similar improvement to placebo in their rhinitis symptoms. The lack of a treatment effect may be in part due to the overall good air quality present throughout the study or an insufficient dose or duration of FFNS. The safety findings showed FFNS 110 mcg once daily to be well tolerated.

Fluticasone furoate nasal spray: a single treatment option for the symptoms of seasonal allergic rhinitis.

BACKGROUND: Fluticasone furoate (USAN-approved name) is a novel, enhanced-affinity glucocorticoid administered in a unique side-actuated device for the management of seasonal allergic rhinitis (SAR). OBJECTIVE: We sought to evaluate the efficacy and safety of once-daily fluticasone furoate nasal spray, 110 microg, in patients aged 12 years or older with fall SAR. METHODS: Patients (n = 299) received fluticasone furoate or placebo for 2 weeks in this double-blind, parallel-group randomized study. Patients evaluated nasal and ocular symptoms using a 4-point categoric scale. Efficacy was assessed on the basis of the mean change from baseline in reflective and instantaneous total nasal symptom scores and reflective total ocular symptom scores. RESULTS: Fluticasone furoate produced significantly greater improvements than placebo in daily reflective total nasal symptom score (-1.473, P < .001; primary end point), morning predose instantaneous total nasal symptom score (-1.375, P < .001), daily reflective total ocular symptom score (-0.600, P = .004), and patient-rated overall response to therapy (P < .001). The onset of therapeutic effect occurred at 8 hours after initial administration. Fluticasone furoate was well tolerated. CONCLUSION: Fluticasone furoate, 110 microg once daily, was effective and well tolerated for the treatment of nasal symptoms of SAR in patients aged 12 years and older. Treatment also produced significant improvements in ocular symptoms. Fluticasone furoate was fast acting, as indicated by an 8-hour onset of action, and provided 24-hour symptom control. CLINICAL IMPLICATIONS: New treatments for the bothersome symptoms of SAR are needed. One such treatment, fluticasone furoate nasal spray, provides effective relief of the symptom profile of SAR.

Optimal dose selection of fluticasone furoate nasal spray for the treatment of seasonal allergic rhinitis in adults and adolescents.

Efficacy and safety of fluticasone furoate nasal spray, administered using a unique side-actuated device, were evaluated in patients > or =12 years of age with seasonal allergic rhinitis to determine the optimal dose. A randomized, double-blind, parallel-group, placebo-controlled, dose-ranging study was performed on 641 patients who received placebo (n=128) or fluticasone furoate, 55 microg (n=127), 110 microg (n=127), 220 microg (n=129), or 440 microg (n=130), once daily for 2 weeks. Fluticasone furoate was significantly more effective than placebo for mean changes from baseline over the 2-week treatment period in daily reflective total nasal symptom score (primary end point; p < 0.001 each dose vs. placebo), morning predose instantaneous total nasal symptom score (p < 0.001 each dose versus placebo), daily reflective total ocular symptom score (p < or = 0.013 each dose versus placebo), and morning predose instantaneous total ocular symptom score (p < or = 0.019 for three highest doses versus placebo). The onset of action for fluticasone furoate nasal spray versus placebo was observed 8 hours after the first. dose of study medication in the 110 and 440 microg treatment groups (p < or = 0.032). The incidence of adverse events, results of clinical laboratory tests, and changes in 24-hour urinary cortisol values were similar between active treatment groups and placebo. The preliminary profile of fluticasone furoate is that of a rapidly effective therapy that confers 24-hour efficacy for both nasal and ocular symptoms with once-daily dosing. The 110-microg dose was chosen for phase III development because it achieved statistically significant and clinically meaningful results for all efficacy end points and provided the optimal risk-benefit ratio.
