Summary

The aim of this study is to determine the optimal concentration of grass pollen allergens inducing rhinoconjunctivitis in subjects allergic to grass pollen in ALYATEC allergen exposure chamber.

Four concentrations of grass pollen allergen (Phl p 5) are tested during 3-hour exposures: 0, 30, 60 and 90 ng/m3.

Conditions

  • Allergic Rhinitis Due to Grass Pollen

Interventions

OTHER

Grass Pollen Allergen Exposure

After the screening visit, subjects are randomized into 3 groups presenting a sequence of allergen concentrations with randomly defined concentrations of Ph l p 5 (0, 30, 60 and 90 ng/m3). Each participant undergo four different 3-hour exposure sessions to grass pollen allergen corresponding to the four different allergen concentrations.
