Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Major Symptom Complex (MSC) Score Over Period I
Time Frame: Baseline, Treatment Period 1 [Day 1, from drug intake (at 11:00 am) to 5 hours post-treatment (at 4:00 pm)]
|
Six individual symptoms which are most dominant in the rhinitis symptom profile will be combined to form the MSC severity score: Runny nose (right and left), itchy nose (right and left), sniffles, nose blows, sneezes, watery eyes. Each individual symptom, except nose blows and sneezes, is rated on a 5-point scale of severity: 0 = None, 1 = a little, 2 = Moderate, 3 = Quite a bit, 4 = severe, 5 = very severe. For nose blows and sneezes, the subjects had to record the number of each symptom since last evaluation. This number corresponds to a score ranging from 0 to 8. The total MSC score ranges from 0 - 36. Increasing scores are associated with increasing severity. Negative values indicate improvement from Baseline. |
