Overview
Brief Summary
Allergic rhinitis is an inflammatory disorder of the upper airway that occurs following allergen exposure. The focus of this study, seasonal allergic rhinitis (SAR), is one type of allergic rhinitis that is triggered by the pollen from trees, grasses, and weeds. Commonly referred to as "hay fever", it is characterized by sneezing, nasal congestion and pruritus, rhinorrhea, and pruritic, watery, red eyes. The purpose of this study is to evaluate the onset of action of an investigational nasal spray, GW685698X aqueous nasal spray, versus vehicle placebo nasal spray in the treatment of seasonal allergic rhinitis caused by ragweed following a single dose of treatment in controlled pollen concentrations in an allergen challenge chamber.

Outcomes
Primary Outcomes
Mean change from baseline in subject-rated total nasal symptom score following a single dose of GW685698X aqueous nasal spray during exposure to ragweed pollen over a 12-hour period.
Secondary Outcomes
- Change from baseline in the individual nasal symptom scores of rhinorrhea, nasal congestion, nasal itching and sneezing, assessed hourly during the 12-hour, post-dose exposure period to ragweed pollen in the allergen challenge chamber.
