DBV Technologies Announces Publication of Positive Viaskin Peanut Data From NIAID-Sponsored Phase II Academic Study in the Journal of Allergy and Clinical Immunology

DBV TECHNOLOGIES (Euronext: DBV – ISIN: FR0010417345 - Nasdaq Stock Market: DBVT) today announced the publication of 12-month results from CoFAR6, a Consortium of Food Allergy Research (CoFAR) study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), investigating the use of Viaskin Peanut for the treatment of peanut-allergic patients 4 to 25 years of age. The primary endpoint of the study, which measured a statistically significant desensitization to peanut, was met, with a greater clinical benefit reported in younger participants. The authors of the publication concluded that Viaskin Peanut was safe and could potentially be a convenient mode of treatment for peanut allergy.

Results from the CoFAR6 study were previously announced and presented at the 2016 American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting in March 2016 in Los Angeles, CA.

"No FDA-approved treatment for peanut allergy exists today. Risks of severe reactions from accidental exposure are a constant threat for these patients, even when following a peanut-free diet,” said Dr. Stacie Jones, Professor of Pediatrics, University of Arkansas for Medical Sciences, Arkansas Children’s Hospital, Little Rock, AR, and lead author of the publication. "A novel treatment that can provide an essential balance between safety and efficacy will be of key importance in the treatment of these patients. The results from CoFAR6 with Viaskin Peanut are promising, and we are looking forward to learning more about this new treatment modality.”

Viaskin Peanut is the company’s lead product candidate, which is based on epicutaneous immunotherapy (EPIT), a proprietary technology platform that can deliver biologically active compounds to the immune system through the skin.

The CoFAR6 study publication, titled Epicutaneous Immunotherapy for the Treatment of Peanut Allergy in Children and Young Adults, was published online ahead of print in the Journal of Allergy and Clinical Immunology (JACI): www.jacionline.org/inpress (DOI: 10.1016/j.jaci.2016.08.017).

About the CoFAR6 Study

In October 2013, CoFAR launched a multi-center, randomized, double-blind, placebo-controlled trial to evaluate Viaskin Peanut in children, adolescents and young adults allergic to peanuts. This trial is sponsored and funded by the NIAID and led by Dr. Stacie Jones. The CoFAR6 trial is being conducted in five hospitals in the United States, and 75 patients were enrolled; 54 children four to 11 years of age and 21 adolescents and adults 12 to 25 years of age. In CoFAR6, subjects were randomized 1:1:1 to two doses of Viaskin Peanut (100 µg and 250 µg) or placebo. The primary outcome measure was percent of patients desensitized to peanut protein during peanut protein oral food challenge (OFC) at week 52. Responders were characterized as patients who successfully passed a 5044 mg OFC or who successfully consumed a dose ten times greater as compared to baseline.
