* House Dust Mites

Since its IPO, the most upstream development program in DBV's pipeline, Viaskin house dust mites (HDM ') has been slightly delayed. The Company has indeed chosen to wait in order to apply for a grant with OSEO-ISI in order to support part of this development, that it obtained late 2012. Moreover, initially scheduled for late 2012, the beginning of the clinical development program of Viaskin ® Milk was also delayed by a few months due to the numerous scientific consultations needed to develop an optimal clinical protocol.

About DBV Technologies:

DBV Technologies is developing Viaskin®, an innovative new approach to the treatment of allergies – a major public health issue that is constantly increasing in prevalence. Food allergies represent a true handicap in everyday life for millions of people, constituting a major unmet medical need. DBV Technologies, incorporated in France in 2002, has developed a proprietary, worldwide-patented technology for administering an allergen to intact skin while avoiding transfer to the blood. The Viaskin® technology combines efficacy and safety as part of a treatment that seeks to improve the patient's tolerability of peanuts, and thus considerably lowers the risk of a systemic, allergic reaction in the event of accidental exposure The product's clinically proven safety profile enables the application of effective desensitization techniques in the most severe forms of the allergy.

DBV Technologies is focusing on food allergies, including milk and peanut, for which there are currently no effective treatments. DBV Technologies has designed two products: Viaskin® Peanut and Viaskin® Milk. The clinical development program for Viaskin® Peanut has received Fast Track designation from the US Food and Drug Administration and is currently being studies in Phase II program. The company will subsequently develop a Viaskin® patch for young children with house dust mite allergy – a true public health issue because this pathology is a primary risk factors for childhood asthma.
