BACKGROUND: Fluticasone furoate (FF) is a novel enhanced-affinity corticosteroid for the treatment of allergic rhinitis, delivered by a unique side-actuated device. This study was designed to investigate the efficacy and safety of FF nasal spray (FFNS) 110 microg once daily compared with placebo in adults and adolescents (aged > or =12 years) with seasonal allergic rhinitis (SAR) symptoms caused by mountain cedar (Juniperus ashei) pollen. METHODS: This was a randomized, double-blind, placebo-controlled, parallel-group, phase III study conducted over a 2-week period (between 10 December 2004 and 19 January 2005) at seven study sites, in Austin, Texas, USA, and San Antonio, Texas, two metropolitan cities in the central Texas Hill Country located approximately 80 miles apart. Adult and adolescent patients (aged > or =12 years) with SAR, who were sensitized to mountain cedar (Juniperus ashei) pollen, were randomized to receive either FFNS 110 microg (n = 152) or placebo (n = 150) once daily. Patients rated the severity of each nasal symptom (rhinorrhea, nasal congestion, nasal itching, and sneezing) and ocular symptom (redness, watery eyes, itching and burning) on a 4-point categorical scale (0 = none, 3 = severe) in a reflective and instantaneous manner. Patients also rated their overall evaluation of response to therapy. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT00115622. RESULTS: FFNS significantly improved the nasal symptoms of SAR compared with placebo. The least square (LS) mean difference in the reflective total nasal symptom score (TNSS) was -0.777 (p = 0.003). A significant reduction in morning pre-dose instantaneous TNSS was also observed compared with placebo (LS mean difference -0.902; p < 0.001). Patients receiving FFNS had significantly greater improvements from baseline in reflective total ocular symptom scores (TOSS) than those receiving placebo (LS mean difference -0.546; p = 0.008). Significant improvements in ocular symptoms with FFNS versus placebo were also observed for morning pre-dose instantaneous TOSS (LS mean difference -0.519; p = 0.009). FFNS had a favorable safety and tolerability profile: fewer adverse events occurred with FFNS (22%) than with placebo (29%), and no serious adverse events were observed. CONCLUSIONS: FFNS 110 microg once daily demonstrated efficacy in relieving both the nasal and ocular symptoms of SAR in adult and adolescent patients.
