Clinical Trial Summary

This pilot study is a Phase IV, single center, placebo-controlled, parallel study design conducted using the Environmental Exposure Unit (EEU). The study will aim to be determine whether there are any benefits from Grastek® for the treatment of birch-pollen induced allergic rhinoconjunctivitis. Grastek® is a Health Canada and FDA approved sublingual immunotherapy (SLIT) for the treatment of grass-pollen induced allergic rhinoconjunctivitis. The EEU provides a closed environment in which participants are exposed to a predetermined, controlled, constant level of airborne pollen. 96 participants will complete this study and will either receive Grastek® or placebo in a 1:1 ratio. The study will consist of a screening visit, a pre-treatment pollen exposure visit, 60 days of treatment with Grastek® or placebo, two treatment visits and a follow-up pollen exposure visit.
