Efficacy and safety of fluticasone furoate nasal spray, administered using a unique side-actuated device, were evaluated in patients >= 12 years of age with seasonal allergic rhinitis to determine the optimal dose. A randomized, double-blind, parallel-group, placebo-con trolled, dose-ranging study was performed on 641 patients who received placebo (n = 128) or fluticasone furoate, 55 mu g (n = 127), 110 mu g (n = 127), 220 mu g (n = 129), or 440 mu g (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 <= 0.013 each dose versus placebo), and morning predose instantaneous total ocular symptom score (p <= 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 mu g treatment groups (p <= 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-mu g 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.
