NCT01889875

Brief Summary

Treatment of pollen allergies can be roughly divided into symptomatic treatment (e.g. antihistamines, steroids) and potentially curative immunotherapy. Immunotherapy can be delivered using subcutaneous or oral (mucosal) routes, with similar clinical outcome. The study seeks to compare immunological changes during subcutaneous (SCIT) and sublingual tablet (AIT) immunotherapy of grass pollen allergy (hayfever).
