BACKGROUND: Mometasone furoate nasal spray (MFNS) improves nasal symptoms and reduces polyp size in adults with nasal polyposis. This 4-month, multinational, randomized, double-blind study was conducted to assess the safety of MFNS in pediatric subjects aged 6-17 yr. METHODS: Subjects aged 6-11 yr with bilateral nasal polyps received MFNS 100 μg once or twice daily or placebo; those aged 12-17 yr received MFNS 200 μg once or twice daily or placebo. End-points included change in 24-h urinary free cortisol (primary), change in 24-h urinary free cortisol corrected for creatinine (key secondary), and adverse events. Efficacy parameters included polyp size, nasal symptoms, and investigator-evaluated therapeutic response, although the study was not powered for statistical analysis of efficacy. RESULTS: Least squares baseline mean urinary free cortisol level (nmol/24 h) for both age groups combined (N = 127) was 49.5 in the MFNS once-daily group, 39.6 in the MFNS twice-daily group, and 49.8 in the placebo group. Change in 24-h urinary free cortisol did not significantly differ among MFNS- and placebo-treated subjects. Least squares mean 24-h urinary free cortisol levels corrected for creatinine also showed no significant differences among MFNS- and placebo-treated subjects. No safety issues emerged. CONCLUSIONS: Results of this study confirm the safety profile of MFNS in pediatric patients with bilateral nasal polyps over 4 months, even at double the recommended pediatric dosage for allergic rhinitis.
