A Randomized, Double Blind, Placebo-Controlled, Parallel Group Study to Investigate the Relative Efficacy and Safety of Immunotherapy With rBet v1-FV Compared to Placebo in Birch Pollen-Allergic Patients With IgE-Mediated Seasonal Allergic Rhinoconjunctivitis
The purpose of this study is to find out if rBet v1-FV works to relieve Seasonal Allergic Rhinitis symptoms compared to Placebo (an inactive substance that looks like rBet v1-FV and also contains Aluminum Hydroxide but does not contain the experimental drug). rBet v1-FV is a vaccine that works by exposing your immune system to something that resembles birch. This vaccine may help to lessen your allergy symptoms during the natural birch season.
