Dose-Ranging Study of Mometasone Furoate (MK-0887/SCH 032088) Nasal Spray in the Treatment of Children (Ages 6-11) With Seasonal Allergic Rhinitis (C95-161)

Organon and Co679 enrolled

Overview

The purpose of this study was to identify the lowest dosage of mometasone furoate nasal spray (MFNS) that provided adequate efficacy with an acceptable safety profile for children (ages 6-11) with seasonal allergic rhinitis (SAR). The MFNS dose levels of 25, 100, and 200 mcg QD were compared with beclomethasone dipropionate (BDP), as an active control, and placebo.

Inclusion Criteria: * Have at least a one-year history of seasonal allergic rhinitis which previously required treatment for tree and/or grass pollen * Have a positive skin test response to an appropriate tree and/or grass seasonal allergen within the last year. * Must be free of any clinically significant disease other than seasonal allergic rhinitis. * Must be pre-menarcheal. Exclusion Criteria: * History of asthma which requires chronic use of inhaled or systemic corticosteroids. * Current or history of frequent, clinically significant sinusitis or chronic purulent postnasal drip. * History of rhinitis medicamentosa. * History of clinically significant nasal candidiasis. * History of multiple drug allergies or allergy/intolerance to corticosteroids or antihistamines. * History of upper respiratory tract or sinus infection that required antibiotic therapy within the previous 2 weeks, or viral upper respiratory infection within 7 days prior to Screening. * History of nasal structural abnormalities, including large nasal polyps and marked septal deviation, that significantly interfere with nasal air flow. * History of dependence upon nasal, oral or ocular decongestants, or nasal topical antihistamines. * History of investigational drug use in the last 30 days. * History of immunotherapy (desensitizing therapy), unless on a stable maintenance schedule for at least one month prior to Screening.

Outcomes

Primary Outcomes

Change From Baseline in the Total Nasal Symptom Score (TNSS) at Day 8 as Assessed by Investigator

The mean change from baseline at study day 8 was calculated for TNSS as assessed by the investigator. TNSS was a composite of the individual nasal symptom scores of discharge (rhinorrhea), stuffiness, sneezing, and itching. The 4 individual nasal symptom scores were rated by the investigator at the visit as follows: 0=none, 1=mild, 2=moderate, 3=severe. TNSS was the sum of the 4 individual nasal symptom scores (range= 0-12; higher score indicating more frequent/severe nasal symptoms). For each participant, individual scores were totaled and used to calculate the change from Baseline in TNSS at the visit. Participant changes were then used to calculate the mean change for each treatment group at that visit. Change from Baseline = visit score - Baseline score (Day 1 visit). Negative changes indicate a decrease in symptom severity.

Time frame: Baseline (Day 1) and Day 8

Secondary Outcomes

Change From Baseline in the Total Nasal Symptom Score (TNSS) on Day 4 as Assessed by Investigator

The mean change from baseline at study day 4 was calculated for TNSS as assessed by the investigator. TNSS was a composite of the individual nasal symptom scores of discharge (rhinorrhea), stuffiness, sneezing, and itching. The 4 individual nasal symptom scores were rated by the investigator at the visit as follows: 0=none, 1=mild, 2=moderate, 3=severe. TNSS was the sum of the 4 individual nasal symptom scores (range= 0-12; higher score indicating more frequent/severe nasal symptoms). For each participant, individual scores were totaled and used to calculate the change from Baseline in TNSS at the visit. Participant changes were then used to calculate the mean change for each treatment group at that visit. Change from Baseline = visit score - Baseline score (Day 1 visit). Negative changes indicate a decrease in symptom severity.

Time frame: Baseline (Day 1) and Day 4

Change From Baseline in the Total Nasal Symptom Score (TNSS) on Day 15 as Assessed by Investigator

The mean change from baseline at study day 15 was calculated for TNSS as assessed by the investigator. TNSS was a composite of the individual nasal symptom scores of discharge (rhinorrhea), stuffiness, sneezing, and itching. The 4 individual nasal symptom scores were rated by the investigator at the visit as follows: 0=none, 1=mild, 2=moderate, 3=severe. TNSS was the sum of the 4 individual nasal symptom scores (range= 0-12; higher score indicating more frequent/severe nasal symptoms). For each participant, individual scores were totaled and used to calculate the change from Baseline in TNSS at the visit. Participant changes were then used to calculate the mean change for each treatment group at that visit. Change from Baseline = visit score - Baseline score (Day 1 visit). Negative changes indicate a decrease in symptom severity.

Change From Baseline in the Total Nasal Symptom Score (TNSS) [Average of Morning (AM), Evening (PM) Score] Averaged Over Days 1 to 15 as Assessed by Participant

Mean change from baseline (CFB) averaged over study days 1-15 was calculated for TNSS assessed by participants (with assistance from caregiver). Participants scored 4 symptoms (rhinorrhea, stuffiness, itching, sneezing) in diaries using the scale 0=none, 1=mild, 2=moderate, 3=severe. TNSS was the sum of the 4 individual scores (range=0-12; higher score indicating more frequent/severe nasal symptoms.) CFD=the 15-day average score-baseline score. Scores were recorded twice daily, in the morning (AM) and evening (PM). Average AM/PM scores were first calculated separately, then averaged together to obtain the 15-day average score. If diary entries were missing, an average AM or PM score was not calculated. If neither average AM nor PM score were calculated, the total 15-day average score was not calculated. Baseline score=Mean of the Baseline AM (day of visit plus 3 preceding days) and the Baseline PM (3 preceding days) scores. Negative change indicated a decrease in symptom severity.
