Allergic Rhinitis
Conditions
Brief summary
The purpose of this study is to evaluate the onset of action of fluticasone furoate nasal spray compared to olopatadine nasal spray and placebo nasal spray in reducing nasal allergic signs and symptoms following ragweed exposure in the Allergen BioCube (ABC) after single dose administration and six consecutive days of treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Nasal Signs and Symptoms (TNSS) | Evaluated by the subject pre-ABC exposure, every 15 minutes during all ragweed exposures in the ABC, and post-ABC exposure | TNSS (0-12 unit scale) is defined as the sum of the four nasal symptom scores recorded for nasal itching, sneezing, rhinorrhea and nasal congestion. |
Secondary
| Measure | Time frame |
|---|---|
| Peak Expiratory Flow Rate (PEFR) | Measured pre-ABC exposure, every 30 minutes during all ragweed exposures in the ABC, and post-ABC exposure |
| Peak Nasal Inspiratory Flow (PNIF) | Measured pre-ABC exposure, every 30 minutes during all ragweed exposures in the ABC, and post-ABC exposure |
| Headaches | Evaluated by the subject pre-ABC exposure, every 30 minutes during all ragweed exposures in the ABC, and post-ABC exposure |
