Repeat Nasal Allergen Challenge
Assessment of Inflammatory Mediator and Cellular Changes Following Repeated Nasal Allergen Challenge in Subjects With Allergic Rhinitis Sensitive to Timothy Grass Pollen - a Validation Study
This is a non-drug, biomarker study to assess the utility of the model of repeated nasal allergen challenges in subjects with atopic rhinitis as a method of inducing an increased response to inhaled allergen, which will more closely resemble the responses seen during the hayfever season.
