Effect of once-daily fluticasone furoate nasal spray on nasal symptoms in adults and adolescents with perennial allergic rhinitis

Background Intranasal corticosteroids are recommended as first-line therapy for the treatment of allergic rhinitis. Fluticasone furoate is a novel enhanced-affinity glucocorticoid for the treatment of allergic rhinitis. Objective To compare the efficacy and safety of intranasal fluticasone furoate with those of vehicle placebo nasal spray in adult and adolescent patients with perennial allergic rhinitis (PAR). Methods After screening (7-14 days), patients 12 years and older with confirmed PAR were randomized to receive fluticasone furoate, 110 μg once daily, or placebo once daily intranasally for 4 weeks in this double-blind, multicenter study. The primary end point was mean change from baseline during the entire treatment period in daily reflective total nasal symptom score (rTNSS), recorded on diary cards by patients, using a 4-point categorical scale. Results The mean reduction from baseline during the treatment period in daily rTNSS was significantly greater in fluticasone furoate recipients than in placebo recipients ( P = .005). This finding was supported by significantly greater mean reductions in morning rTNSS and evening rTNSS ( P = .004 and P = .011, respectively). A significantly greater mean reduction in instantaneous morning predose TNSS with fluticasone furoate compared with placebo ( P = .006) confirmed the efficacy of once-daily administration. Fluticasone furoate was also significantly more effective than placebo in overall response to therapy ( P = .005). Conclusions Fluticasone furoate nasal spray, 110 μg once daily, effectively relieved nasal symptoms of PAR in adults and adolescents 12 years and older.
