BAGNEUX, FRANCE--(Marketwired - June 20, 2013) - DBV Technologies (EURONEXT PARIS: DBV) (ISIN: FR0010417345)
- Two-thirds of 5-11 years old children reached efficacy endpoint after 18-month treatment
- ARACHILD provides a very good baseline for DBV's ongoing phase IIb ('VIPES') study
DBV Technologies (EURONEXT PARIS: DBV) (ISIN: FR0010417345), creator of Viaskin®, a new standard in the treatment of allergy, announced today the 6-, 12- and 18-month efficacy data of Arachild, a study sponsored by Assistance Publique-Hôpitaux de Paris (AP-HP). The analysis of the data shows that two-thirds of children less than 12 years old reach the efficacy endpoints after 18-month treatment with Viaskin Peanut 100 µg. The serological response observed over the period was robust and strong, implying efficacy of the ongoing desensitization process..
Pr. Jean-Marc Tréluyer of the Unité de Recherche Clinique at Tarnier Hospital (AP-HP, Paris, France) successfully led ARACHILD, one of the largest study ever conducted in food allergy. Pr Christophe Dupont, coordinator of the study, provided DBV with cleaned and comprehensive top-line efficacy data, which were presented to DBV's Scientific Advisory Board on June 14, 2013. The complete efficacy and safety study results should be published in the coming months by Pr. C. Dupont
ARACHILD, a multicenter double blind, placebo-controlled clinical trial was designed to assess the efficacy and safety of epicutaneous immunotherapy (EPIT) using DBV's Viaskin Peanut in 54 randomized subjects aged 5 to 17 with a confirmed severe peanut allergy. Subjects who reacted to a cumulative dose of peanut proteins of less than 300mg were eligible and randomized to either Viaskin Peanut at 100µg of peanut proteins (active group) or to Viaskin Placebo (placebo group) in a 1:1 ratio. At 6 months, all patients were switched to active treatment and received Viaskin Peanut for an additional 12 months.
In the active group (28 subjects), the 12- and 18-month data shows consistent and sustained improvement across the study population, with 20% and 40% of subjects respectively consuming at least 10 times more peanut protein than at the beginning of the trial (defined as 'success' or 'responders'). The preliminary 6-month data released in June 2012 was partially validated after database cleaning; serological results were fully confirmed while no statistical difference appeared anymore in the treated versus placebo groups at food challenge. After 6-month treatment, the analysis (pooled on 50 subjects) shows that 5 children multiplied by at least 10-fold the cumulated reactive dose of peanut proteins compared to baseline versus 2 children in the placebo group (26 subjects).
A specific sub-analysis of results in 19 adolescents (12-17 years old) and 35 children (5 to 11 years old) shows clear-cut trends. Despite a positive serological response, adolescents showed no responders at 6-, 12- and 18-month, while children showed constant and progressive increase in number of responders, with respectively 14.7%, 28.1% and 66.7% of responders at 6-, 12- and 18-month. Overall, children were able to eat on average, after 18 months of Viaskin Peanut treatment, a cumulated reactive dose of approximately 1.5 peanut, compared with traces at the start of the trial. Among the 10 children who passed the food challenge, 4 reached the cumulative reactive dose of more than 1000mg of peanut protein (equivalent to 4 peanuts).
Viaskin® Peanut also showed significant immunological changes (secondary efficacy endpoints) in the overall population, with clear-cut results in children. In treated children, peanut-specific IgE (immunoglobulin E) were increased by more than two-fold at 6-month, before decreasing and approaching toward initial levels at 18-month, while Peanut-specific IgG4 (immunoglobulin G4) increased by more than eight-fold over 18-month of treatment. The trends observed in both indicators suggest - as expected - a successful desensitization process in children while the response observed in adolescents was clear, but not robust enough to generate significant clinical outcomes for that specific patient population.
The Arachild results provide strong support for the continued development of epicutaneous immunotherapy" stated Pr. Hugh Sampson, Chief of the Division of Allergy & Immunology in the Department of Pediatrics, Director of the Jaffe Food Allergy Institute, and Dean of Translational Biomedical Science at The Mount Sinai Medical Center in New York, USA. Pr. Sampson is also a member of DBV's Scientific Advisory Board as well as International Coordinating Investigator for DBV's Phase IIb VIPES clinical trial and Principal Investigator of the National Institutes of Health-sponsored Consortium of Food Allergy Research clinical study with Viaskin Peanut (CoFAR6). "There is an unmet medical need for new therapeutic approaches that could lead to meaningful quality of life improvements for patients who are in constant fear of violent allergic reactions."
Pr. Christophe Dupont, French National Coordinating Investigator of ARACHILD study and Head of the Pediatric-Gastroenterology Ambulatory Department at the Necker Hospital (AP-HP) said: "The Arachild data reveal an interesting trend toward efficacy as the change in peanut consumption observed at 18 months represents an important improvement in the quality of life of patients."
Dr. Pierre-Henri Benhamou, Chairman and CEO of DBV Technologies, said: "The objective of the Arachild study, that was launched in 2010, at a time when DBV had little evidence of the efficacy of its platform in humans, was to gauge the safety and efficacy of Viaskin in severe peanut allergic patients. The results observed at 18-months in children show that the response is robust enough to claim that Viaskin has a clear efficacy." Dr. Pierre Henri Benhamou continued: "I would like to thank the team at AP-HP for leading the way with this first pilot study, that has notably allowed DBV to optimize the development of Viaskin. Thanks to ARACHILD, we have optimized the protocol, methodology and design for DBV's on-going Phase IIb VIPES clinical trial in North America and Europe." Dr. Pierre-Henri Benhamou concluded: "Overall, we believe that Viaskin Peanut has a strong potential to safely treat peanut allergic patients, and that VIPES should provide evidence of efficacy in adolescents and adults, at higher doses."
The French hospitals included in the study were: Necker Hospital (AP-HP, Paris), Lenval Hospital (Nice), Hospices Civils (Strasbourg), Saint-Vincent de Paul Hospital (Lille), and Central Hospital (Nancy).

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