- Early treatment with EPIT® prevents anaphylaxis in a model of successive sensitizations
- If confirmed in humans, these results may transform the management of pediatric allergies
BAGNEUX, France, Jan. 12, 2015 (GLOBE NEWSWIRE) -- DBV Technologies, (Euronext: DBV - ISIN: FR0010417345) (Nasdaq:DBVT), a clinical-stage specialty biopharmaceutical company, announced today the publication of a set of experimental data in the Journal of Allergy and Clinical Immunology (JACI) demonstrating that early treatment with Epicutaneous Immunotherapy (EPIT®) using Viaskin® may induce protection from sensitization to other allergens. The pre-clinical data demonstrate that treatment with EPIT® could prevent further allergies by influencing the natural history of allergy via a Treg-dependent mechanism. This protective response induced by EPIT® is sustained after the end of treatment.
"These new data gives us a new perspective for the treatment of food allergy. This publication shows us the scope of applications for EPIT® in allergy, especially in young children, and we will continue to work on strengthening our understanding of EPIT's mechanism of action with Viaskin®. If confirmed in Humans, this treatment could have the potential to fundamentally transform the management of the allergic disease." said Dr. Pierre-Henri Benhamou, M.D., Chairman and CEO of DBV Technologies.
"We are proud to present this significant breakthrough in characterizing the immunomodulation and epigenetic modifications that are induced by EPIT®. This publication in a reference journal in the field of immunology and allergy encourages us to continue exploring the effect of EPIT and will help guide further clinical developments" said Lucie Mondoulet, PhD., Director of research of DBV Technologies.
In a murine model sensitized to a food allergen, EPIT® through the use of Viaskin® can treat the first allergy, while protecting against anaphylaxis caused by sensitization to other food or respiratory allergens. The experiment shows that EPIT-induced Tregs significantly modified the humoral and cellular response, reduced Th2 cytokines, decreased eosinophilic esophagus infiltration and suppressed airway hyper responsiveness (AHR) and anaphylaxis. Epigenetic results are also provided suggesting that Milk-EPIT enhanced the methylation level of the promoter region of GATA-3, which may explain the prevention of sensitization to peanut and house dust mites, as well as the sustained protective response that was observed.
As a conclusion, three major outcomes have emerged from this study:
- Demonstration of the protective effect of EPIT® to the sensitization to further allergens.
- Validation of the key role for regulatory T cells (Tregs) in the protection against further sensitizations.
- Determination of a sustained protective response induced by EPIT® after the end of treatment.

About DBV Technologies
DBV Technologies is developing Viaskin®, an innovative new approach to the treatment of allergies - a major public health issue that has been increasing in prevalence. 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, and thus considerably lowering the risk of a systemic, allergic reaction in the event of accidental exposure. 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 candidates: Viaskin® Peanut and Viaskin® Milk. The clinical development program for Viaskin® Peanut has received Fast Track designation from the US Food and Drug Administration.
DBV Technologies shares are traded on segment C of Euronext Paris (Ticker: DBV, ISIN code: FR0010417345) and on the Nasdaq Stock Market in the form of American Depositary Shares (each representing one-half of one ordinary share) (Ticker: DBVT).
