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.

Detailed Summary: Randomized, Double Blind, Placebo-Controlled, Single-Dose, Parallel-Group Study to Evaluate the Onset of Action of a Single Dose of Intranasal GW685698X Aqueous Nasal Spray 100 mcg in Adolescent and Adult Subjects (=12 years of age) With Seasonal Allergic Rhinitis Exposed to Ragweed Pollen in an Allergen Challenge Chamber
Sponsor: GlaxoSmithKline

Current Primary Outcome: 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.

Original Primary Outcome:

Current Secondary Outcome: 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.
