Efficacy and Safety of Mometasone Furoate Nasal Spray in Children With Adenoid Hypertrophy. SNORE Study (P05155)

A Double-blind Placebo-controlled, Randomized, Parallel-group, Multicenter Clinical Trial to Evaluate Efficacy and Safety of Mometasone Furoate Nasal Spray in Children With Adenoid Hypertrophy SNORE Study

The purpose of this study is to determine whether 8 weeks treatment with mometasone furoate nasal spray (MFNS), twice daily, is safe and effective in treating adenoid hypertrophy in children.

Inclusion Criteria:

• Participants and their parents must demonstrate willingness to participate and comply with study procedures. Parents must sign a written informed consent
• Participants and their parents must understand and be able to adhere to dosing and visit schedules, and agree to record symptom severity scores, medication times, and concomitant medications accurately and consistently in a daily diary
• Children with a history of adenoid hypertrophy for at least 3 months with no response to previous medical treatment
• Baseline adenoid tissue size must have been graded by nasopharyngoscopy examination as Grade III or IV on the Adenoid/Choana (A/C) Index (between 50% and 100% obstruction)
• Baseline Total Severity Symptoms Score must be ≥ 8 points (AM or PM)
• For inclusion in endpoints relating to otitis media with effusion (OME), participant must have persistent middle ear effusion for the past 3 months or more documented by otoscopic examination, middle ear pressure less than -150 mm H2O, Jerger type B flat tympanogram, and mild-moderate conductive hearing loss in audiometry supporting the diagnosis of OME

Exclusion Criteria:

• Participants with previous surgery of hypertrophic adenoids with or without tympanostomy tube placement
• Participants treated with inhaled or systemic corticosteroids within the past 1 month
• Participants with Morbid Obesity (Body Mass Index >95 percentile of charts from the Centers for Disease Control)
• Participants who have not accomplished the designated washout periods for any of the prohibited medications
• Participants who have used any investigational products within the last 30 days
• Participants who have used any antibodies for allergies in the past 90 days
• Participants who have any abnormal physical examination results that may affect study evaluations or participant safety in the investigator's judgment
• Participants who are allergic or have an idiosyncratic reaction to corticosteroids
• Participants with signs and symptoms of acute or chronic bacterial rhinosinusitis
• Participants has had an upper or lower respiratory tract or sinus infection that required antibiotic therapy with the last dose later than 14 days prior to screening, or who has had a viral upper or lower respiratory infection within 7 days prior to screening
• Participants with a documented immunodeficiency condition
• Participants with nasal structural abnormalities, including large nasal polyps and marked septum deviation that significantly interferes with nasal airflow
• Participants with any clinically significant metabolic, cardiovascular, neurologic, hematologic, gastrointestinal, cerebrovascular, or respiratory disease (other than asthma), or any other disorder which, in the judgment of the Investigator, may interfere with the study evaluations or affect participant safety
