What researchers measure

Primary outcomes

  1. Change From Baseline in Total Nasal Symptom Score (Assessed by Participant)

    Mean change from baseline (CFB), averaged over study days 1-15, is calculated for total nasal symptom scores assessed by participants. Participants scored 4 symptoms (rhinorrhea; nasal stuffiness; nasal itching; sneezing) in diaries on a scale from 0 (none) to 3 (severe). Scores sum to a total nasal symptom score (range: 0-12); higher values indicate greater severity. A decrease in symptom severity is reflected by a negative CFB. CFB is the 15-day average score minus baseline score. Scores were recorded twice daily, in morning (AM) and night (PM). Average AM/PM scores are first calculated separately, then averaged together to compute 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 was calculated, total 15-day average score was not calculated. Baseline score is an average of the three AM and three PM scores preceding treatment.

    Time frame: Baseline and days 1 through 15 (average of 15 days of treatment)

  2. Change From Baseline in Total Symptom Score (Assessed by Participant)

    Mean change from baseline (CFB), averaged over study days 1-15, is calculated for total symptom scores assessed by participants. Participants scored 8 symptoms (rhinorrhea; nasal stuffiness; nasal itching; sneezing; itching/burning eyes; tearing/watering eyes; eye redness; and ear/palate itching) in diaries on a scale from 0 (none) to 3 (severe). Scores sum to a total symptom score (range: 0-24); higher values indicate greater severity. A decrease in symptom severity is reflected by a negative CFB. CFB is the 15-day average score minus baseline score. Scores were recorded twice daily, in morning (AM) and night (PM). Average AM/PM scores are first calculated separately, then averaged together to compute 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 was calculated, total 15-day average score was not calculated. Baseline score is an average of the three AM and three PM scores preceding treatment.

Secondary outcomes

  1. Change From Baseline in Total Nasal Symptom Score on Day 15 (Assessed by Physician)

    The mean change from baseline on study day 15 was calculated for total nasal symptom scores assessed by physician.

Physician scored each symptom during study visit at baseline and study day 15, on a scale from 0 (none) to 3 (severe), totaling to a composite score from 0-12 where a higher value indicates greater severity. A negative change from baseline indicates a decrease in symptom severity.
