DBV Technologies Granted US Patents for Allergen Delivery System VIASKIN(R)

Paris, France – 23 September 2010 – DBV Technologies (DBV), a biotechnology company specializing in innovative products for the diagnosis and the treatment of food allergies, announced today that its unique VIASKIN® delivery system has been granted two US patents. In both cases, the lifetime of the patent has been extended until 2026.

Aspects of both patents (US 7,635,488 and US 7,722,897) are incorporated into DBV Technologies’ VIASKIN which delivers allergens compounds to the immune system though intact skin.

DBV Technologies’ VIASKIN is the first device especially developed for EPicutaneous ImmunoTherapy (EPIT). VIASKIN enhances hydration of the surface of the skin and allows the diffusion of allergens into the superficial layers, so that they can interact with the skin’s immune network in order to desensitize food allergy patients safely without any risk of systemic reactions. VIASKIN is applied on intact skin and is completely non-invasive.

Commenting on the announcement, DBV Technologies’ CEO and Co-Founder, Pierre-Henri Benhamou, MD said: “We are delighted to have secured two patents central to our VIASKIN technology, which further strengthen the competitiveness of our core technology and we are delighted this protection has been granted for an extended period. To date VIASKIN is successfully marketed as a diagnostic product but has also shown huge promise as a safe, painless and effective therapy for food allergy desensitization.”

DBV Technologies recently announced that its lead product VIASKIN PEANUT has been selected to be evaluated in a Phase II study of peanut allergy desensitization led by the U.S. Consortium of Food Allergy Research (CoFAR) and funded by the National Institutes of Health (NIH).

About DBV Technologies’ Peanut Specific EPIT program

Through its Peanut Specific EPIT program, DBV Technologies aims to safely desensitize patients suffering from peanut allergy, i.e. increase the amount of peanuts that patients can consume symptom-free. Early July 2010, DBV Technologies announced that the U.S. Food and Drug Administration (FDA) has accepted the Investigational New Drug (IND) application of its lead food allergy desensitization candidate, VIASKIN PEANUT, for the desensitization to peanut allergy. The U.S. Medical Centres participating in the first-in-man clinical trial are: Duke University Medical Center, Durham, NC; The National Jewish Medical & Research Center, Denver, CO; Arkansas Children’s Hospital Research Institute, Little Rock, AR, Aspen CR, Orem, UT; and CRI Worldwide, Willingboro, NJ.

According to the American Academy of Allergy Asthma & Immunology statistics, peanut allergy is one of the most prevalent food allergies in the U.S. with over 2 million people suffering from this allergy. In the U.S. alone, food allergies are responsible for about 125,000 emergency room visits and 150-200 deaths per year, fatal food anaphylaxis being most often caused by peanuts. Due to the potentially fatal consequences of peanut allergy, this condition represents a major health concern worldwide and imposes severe social and quality of life restrictions on afflicted individuals.

DBV Technologies has already published strong pre-clinical data supporting its peanut allergy EPIT program. These are available for review on the Scientific Publications page on the DBV Technologies website. To date, no food allergy desensitization treatment is currently marketed for the treatment of food allergies such as peanut allergy.

About VIASKIN®

DBV Technologies’ patented VIASKIN® technology is a unique delivery system which retains active compounds on a carrier using electrostatic forces only. The delivery platform allows active compounds to be presented to the epidermis of the skin without breaking the blood-skin barrier. In not breaking the blood-skin barrier, DBV Technologies’ allergen diagnosis and Epicutaneous specific ImmunoTherapy (EPIT) should avoid inducing systemic shock – one of the most serious concerns associated with current desensitization therapies.
