A Study of the Effectiveness and Safety of Mometasone Furoate Nasal Spray (MFNS, SCH 032088) for the Treatment of Nasal Polyps (P05604)

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the effectiveness and safety of MFNS in improving nasal congestion/obstruction and in reducing bilateral nasal polyps.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Congestion/Obstruction Score | At Baseline, the Investigator and participant jointly evaluated the signs and symptoms of congestion/obstruction. After Baseline, participants scored the signs and symptoms of congestion/obstruction every morning immediately prior to dosing using a morning instantaneous congestion/obstruction score. This score reflected the participant's condition at that time (instantaneous) and ranged from 0 to 3 (0=none, 1=mild, 2=moderate, 3= severe), with a lower score indicating less congestion/obstruction. Congestion/obstruction scores were averaged over Weeks 1-4 of the treatment period. Data are compared using Least Square (LS) Means. LS Mean Change from Baseline = LS Mean Score averaged over Weeks 1-4 - LS Mean Score for Baseline. | Baseline and Weeks 1-4 | 
| Change From Baseline in Total Polyp Size Score | An endoscopic nasal examination was performed by the Investigator. Bilateral nasal polyps were scored as follows for each notril (left and right): 0=no polyps, 1=polyps in middle meatus not reaching below inferior border of middle turbinate, 2=polyps reaching below inferior border of middle turbinate but not inferior border of inferior turbinate, 3=large polyps reaching to or below the lower borders of the inferior turbinate or polyps medial to the middle turbinate. Total polyp size score ranged from 0 to 6 (scored 0 to 3 for each nostril), with a lower score indicating smaller-sized polyps. LS Mean Change from Baseline = LS Mean Score for Week 16 - LS Mean Score for Baseline. | Baseline and Week 16 |
