Effectiveness and Safety of Once or Twice Daily Mometasone Nasal Spray Versus Amoxicillin Versus Placebo for Treatment of Acute Rhinosinusitis (Phase 3 Study)(Study P02692)

Study Overview
=================
Brief Summary
-----------------
This study was conducted to compare the effectiveness and safety of mometasone nasal spray once daily or twice daily with amoxicillin or with placebo in treating the signs and symptoms of acute rhinosinusitis. Patients received mometasone nasal spray 2 sprays per nostril once daily, 2 sprays per nostril twice daily, amoxicillin 500 mg three times a day, or placebo three times a day. Patients on nasal spray were treated for 15 days and patients on amoxicillin or placebo were treated for 10 days. All patients were followed-up with a 14-day no-treatment observation period.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average AM/PM major-symptom score (sum of rhinorrhea, post nasal drip, nasal congestion/stuffiness, sinus headache, and facial pain/pressure/tenderness on palpation over the paranasal sinuses) over the Treatment Phase of 15 days. |  | Over 15 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The total-, major-, and individual-symptom scores (for AM, PM, and AM/PM average) by week, and for Days 1-15, and 16-29. |  | At end of each week, over Days 1-15, and Days 16-29 | 
| Time to onset of action in the major-symptom score, defined as the first day active treatment was statistically significantly different from placebo, and sustained thereafter. |  | Throughout the Treatment Period | 
| Comparison between the groups of therapeutic response |  | At Visit 4 or the last treatment visit | 
| Proportion of subjects who were considered by the investigator to be treatment failures, and proportion of subjects who discontinued early due to treatment failure |  | Throughout the study |
