title: The efficacy and safety of once-daily mometasone furoate nasal spray in nasal polyposis: a randomized, double-blind, placebo-controlled study.
abstract: CONCLUSIONS
  In subjects with mild-to-moderate nasal polyposis, treatment with mometasone furoate nasal spray (MFNS) 200 microg once daily (QD) significantly decreases nasal congestion, reduces polyp size, and improves quality of life.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of MFNS, administered QD in the morning, in subjects with mild-to-moderate nasal polyposis.
  
  
  METHODS
  This randomized, double-blind, double-dummy, placebo-controlled clinical trial enrolled subjects with mild-to-moderate nasal polyposis at 12 centers in Denmark, Finland, Norway, and Sweden. Inclusion criteria were: age > or = 18 years, a diagnosis of bilateral nasal polyps, and clinically significant nasal congestion. Following a 2-4-week run-in period, subjects were randomized to receive MFNS 200 microg QD or matching placebo for 16 weeks.
  
  
  RESULTS
  A total of 298 subjects were randomized to treatment. Of those subjects included in the intent-to-treat efficacy analysis (n = 291), a statistically greater proportion of the MFNS group than the placebo group had improvements in investigator-assessed nasal congestion score between baseline and end point (the primary outcome) (74.3% vs 46.8%; p < 0.001). Significant benefits of MFNS were also seen for secondary end points, including polyp size, sense of smell, peak nasal inspiratory flow, therapeutic improvement, and quality-of-life measures. MFNS was well tolerated, with no unusual or unexpected adverse events.
