Abstract
BACKGROUND: The effect of fluticasone furoate nasal spray (FFNS) on growth in prepubescent children has not been evaluated. OBJECTIVE: To characterize the difference in mean prepubescent growth velocities, as determined by stadiometry, between patients treated continuously for 1 year with FFNS 110 mcg once daily and placebo nasal spray. METHODS: This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group 76-week safety study. Nasal symptom assessments were used as a measure of adherence. Eligible patients were ages 5 to <8.5 years at screening and had at least a 1-year clinical history and diagnosis of perennial allergic rhinitis, including a positive skin test or specific IgE to an appropriate perennial allergen within the past year. RESULTS:One hundred eighty-six patients in the FFNS group and 187 patients in theplacebo group completed the entire 52-week treatment period. During treatment, the least squares mean growth velocity was 5.19 cm/y for the FFNS group and 5.46 cm/y for the placebo group; mean difference, -0.270 cm/y (95% CI, -0.48 to -0.06 cm/y). Other safety assessments, including 24-hour urinary cortisol excretion, were comparable between the treatment groups. Daily reflective total nasal symptom scores declined similarly in both the FFNS and placebo groups. CONCLUSION: Once-daily treatment with FFNS over 52 weeks in prepubescent children resulted in a small reduction in growth velocity compared with placebo. Clinicians will need to balance the reduction in growth observed with FFNS to its potential for clinical benefit.
