 Project objective

Allergy is a rapidly increasing, global problem that already affects 1 billion people and causes significant social and economic burden. In Europe, allergic rhinitis and asthma cause more than 100 million missed work and school days per year. Allergy is usually managed by avoiding the allergen or by medication that temporarily alleviates the symptoms. The only disease-modifying treatment available to date is allergen immunotherapy (AIT) where long-term symptom relief is achieved by training the immune system to tolerate allergens. However, typical AIT takes 3-5 years, involves monthly injections or daily drops/tablets and has the risk of serious allergic reactions during treatment. Thus, the popularity of AIT is still relatively low compared to symptomatic drugs. We have developed a platform technology for creating modified hypoallergens to be used in AIT. It is based on making small, highly targeted modifications to allergen proteins that reduce their ability to trigger allergic reactions during treatment without compromising their efficacy in building tolerance to natural allergens. With these modified hypoallergens, we expect to shorten the injectable AIT treatment from dozens of injections over 3 years to just 3-6 injections over a few months. From the clinically important major birch pollen allergen Bet v 1 we have created rBet v 1 dm hypoallergen. In preclinical tests it has shown 100-fold reduction in histamine release compared to natural allergens and induced similar immunological responses in mice that are desired in human AIT. In the AllergyVAX project we will test rBet v 1 dm for maximum tolerated dose and immunogenicity in allergic patients in a phase I/IIa clinical trial. The project will facilitate seamless transition to phase IIb-III clinical development, establishing a basis for product launch with selected partners and advancing other hypoallergens in the pipeline, including product candidates for grass pollen, dog, horse and peanut allergies.
