No mucosal atrophy and reduced inflammatory cells: active-controlled trial with yearlong fluticasone furoate nasal spray.

BACKGROUND: Fluticasone furoate nasal spray (FFNS) and mometasone furoate nasal spray (MFNS) are well tolerated and more effective than placebo at relieving the symptoms of seasonal and perennial allergic rhinitis. Effects of FFNS on the nasal histology have not been previously reported. This study examines the effects of FFNS and MFNS, administered daily for 1 year, on the nasal mucosa in subjects with perennial allergic rhinitis. METHODS: Subjects with perennial allergic rhinitis were randomized 1:1 to q.d., open-label treatment with FFNS, 110 µg, or MFNS, 200 µg, for 1 year. These groups and a healthy control group that did not receive study medication underwent nasal biopsies at baseline and 12 months. RESULTS: The nasal biopsy population comprised 96 participants (37 using FFNS, 42 using MFNS, and 17 healthy controls). Epithelial thickness did not change appreciably from baseline to week 52 in any of the groups and mean change from baseline did not differ between FFNS and MFNS (least square mean difference, -0.001 mm, 95% confidence interval, -0.007, 0.006). Although not tested for significance, improvements over baseline were observed in epithelial histology in the FFNS group with more epithelium including intact columnar and ciliated epithelial cells. No appreciable change in the percentage of goblet cells was established. FFNS and MFNS were associated with decreases in epithelial and subepithelial nasal mucosal eosinophils and basophils from baseline to week 52. The percentage of subjects with no inflammatory cells at week 52 was 49 and 33% for eosinophils and 46 and 24% for basophils, for FFNS and MFNS, respectively. CONCLUSION: Yearlong therapy with either FFNS or MFNS showed no changes in epithelial thickness or the percentage of goblet cells as well as a reduction in inflammatory cell infiltrate. FFNS was associated with improvements in epithelial histology. These data support the long-term safety of FFNS in subjects with perennial allergic rhinitis.

Safety and efficacy of fluticasone furoate in pediatric patients with perennial allergic rhinitis.

OBJECTIVE: To evaluate the safety and efficacy of once-daily (QD) fluticasone furoate (FF) nasal spray in children with perennial allergic rhinitis (PAR). STUDY DESIGN: A global, randomized, double-blind, placebo-controlled study. SUBJECTS AND METHODS: Pediatric patients (aged 2-11 years; n = 558) with PAR received once-daily placebo, FF 110 microg, or FF 55 microg for 12 weeks. Efficacy was evaluated by nasal symptom scores. General safety and corticosteroid-specific safety (nasal and ophthalmic examinations, and hypothalamic-pituitary-adrenal assessments) were assessed. RESULTS: No findings of clinical concern were identified from the safety assessments. For primary efficacy analysis of mean change from baseline over the first 4 weeks of treatment in daily reflective total nasal symptom score, FF 55 microg demonstrated significant improvement (P = 0.003) compared with placebo; however, the improvement for FF 110 microg versus placebo did not reach statistical significance (P = 0.073). CONCLUSION: FF QD was well tolerated and demonstrated efficacy in children aged 2 to 11 years with PAR.
