A Study to Compare the Efficacy of Levocetirizine to Placebo in Reducing Symptoms of Seasonal Allergic Rhinitis (SAR) in Sensitive Subjects Exposed to Ragweed Pollen
Double Blind, Double-dummy, Five Parallel Groups, Randomized, Exploratory Clinical Trial to Compare the Efficacy of Single Dose of Levocetirizine 2.5 mg Oral Drops (5 mg/mL), Levocetirizine 5 mg Oral Tablets, Cetirizine 5 mg Oral Drops (10 mg/mL) and Cetirizine 10 mg Oral Tablets to Placebo in Reducing Symptoms of Seasonal Allergic Rhinitis (SAR) in Ragweed Sensitive Subjects Exposed to Ragweed Pollen in an Environmental Exposure Unit (EEU)

Brief Summary
The purpose of the study is to assess the efficacy comparability of cetirizine and levocetirizine, by comparing the effects of single intake of the two drugs to placebo in reducing symptoms of seasonal allergic rhinitis (SAR) in ragweed sensitive adult subjects exposed to ragweed pollen in an Environmental Exposure Unit.

Outcome Measures
Primary Outcomes (1)
Change From Baseline in the Major Symptom Complex (MSC) Score Over Period I
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.
Baseline, Treatment Period 1 [Day 1, from drug intake (at 11:00 am) to 5 hours post-treatment (at 4:00 pm)]
Secondary Outcomes (8)
Change From Baseline in the MSC Score Over Period II
Baseline, Treatment Period II [Day 2, (8:30 am to 12:00 pm)]
Change From Baseline in the MSC Score Over the Total Treatment Period (Period I + Period II)
Baseline to Day 2
Change From Baseline in the Total Symptom Complex (TSC) Score Over Period I
Baseline, Treatment Period I [Day 1, from drug intake (at 11:00 am) to 5 hours post-treatment (at 4:00 pm)]
Change From Baseline in the Total Symptom Complex (TSC) Score Over Period II
Baseline, Treatment Period II [Day 2, (8:30 am to 12:00 pm)]
