  Purpose

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.

Criteria

Inclusion Criteria:

  1. Male and female subjects with a history of seasonal (intermittent) atopic rhinitis, aged 18-40 years.
