Regulatory News:

DBV Technologies (Euronext: DBV – ISIN: FR0010417345), creator of Viaskin®, a new standard in the treatment of allergy, announced today that the first patient has been enrolled, on July 31, in the VIPES phase IIb clinical study (Double-Blind, Placebo-Controlled, Randomized Phase IIb trial to study VIaskin® Peanut’s Efficacy and Safety in peanut allergy). VIPES is a 12-month, multicenter and multinational study conducted in Europe and in North America, encompassing 6 countries, with a total of approximately 20 to 25 Investigators. The 220 Peanut-allergic subjects will range from 6 to 55 years of age with a history of immediate hypersensitive reaction to peanut protein.

, M.D., Chairman and CEO of DBV Technologies said:

Peanut is an ubiquitous ingredient in food, and contaminations of foods that are not supposed to contain peanut occur quite regularly. As a consequence, strict avoidance is difficult to achieve and accidental ingestion of peanuts by peanut-allergic subjects is frequent, with severe and potentially life-threatening reactions ensuing. The only available countermeasure in case of severe systemic and/or life-threatening reactions/anaphylaxis to peanuts is injectable epinephrine as recommended by the WHO.

Three doses of peanut proteins, i.e. 50 µg, 100 µg and 250 µg per patch will be evaluated in the study versus placebo. To be eligible and enrolled in the study, the subjects must be truly allergic to peanut as confirmed by a double blind placebo-controlled food challenge to peanut. Repeated daily application of Viaskin will be made over a 12-month double-blind treatment period, each Viaskin being applied for a duration of 24 hours, either on the upper arms for adults (18-55 years) and adolescents (12-17 years) or on the back for children (6-11 years). .

The objectives of this 12-month dose-finding study with Viaskin® Peanut are as follows:

The Principal Coordinating Investigator for North America is , M.D., Professor of Pediatrics and Director of The Jaffe Food Allergy Institute at Mount Sinai School of Medicine. In Europe, the Principal Coordinating Investigator is , M.D, Ph.D., Necker Sick Children's Hospital, and co-founder of DBV Technologies. VIPES results would be available first half 2014.

In the US about 1.1% of the general population (i.e. over 3 million people) is allergic to peanut. In the US, peanut allergy causes about 100 to 150 deaths per year. This allergy affects both adults and children and it has been estimated that peanut allergy affects 1.8% of young children in the United Kingdom. The prevalence of peanut allergy in other Western countries (e.g. Canada, France and Spain) has been studied by many researchers and ranges from 0.9% to 1.5%. This allergy is generally considered to be persistent; many studies indicate that fewer than 20% of children will outgrow their peanut allergy. Peanut allergy is more severe than other common food allergies (e.g. milk and egg allergies).

DBV Technologies is opening up a decisive new approach to the treatment of allergy – a major public health issue that is constantly increasing in prevalence. Food allergies represent a true handicap in everyday life for millions of people and thus constitute a major unmet medical need. DBV Technologies has developed a unique, proprietary, worldwide-patented technology for administering an allergen to intact skin and avoiding massive 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 peanut and thus considerably lower the risk of a systemic, allergic reaction in the event of accidental exposure to the allergen. The company's significant development program has taken this revolutionary method through to the industrial stage in Europe, initially. The product's clinically proven safety of use enables the application of effective desensitization techniques (the efficacy of which is acknowledged worldwide) in the most severe forms of the allergy. DBV Technologies is focusing on food allergies (milk and peanut) for which there are currently no effective treatments. It has developed 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. 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 one of the main risk factors for childhood asthma. DBV Technologies shares are traded on segment C of Euronext Paris (Ticker: DBV, ISIN code: FR0010417345).
