DBV Technologies Announces Submission of Biologics License Application for Viaskin Peanut to the U.S. Food and Drug Administration

DBV Technologies (Euronext: DB - ISIN: FR0010417345 - Nasdaq Stock Market: DBVT) today announced the submission of a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for Viaskin Peanut for the treatment of peanut allergy in children four to 11 years of age. Viaskin Peanut is the Company's lead product candidate, which is based on epicutaneous immunotherapy (EPIT), a proprietary technology platform that delivers biologically active compounds to the immune system through the skin.

"This submission represents a significant step forward for those families living with peanut allergy. We are thankful for the patients, investigators and DBV employees' efforts in making this milestone possible," said Dr. Pierre-Henri Benhamou, Chairman & Chief Executive Officer of DBV Technologies. "We have been developing Viaskin Peanut for over 10 years, with over 1,000 patients studied in our clinical trials, and we are excited about the possibility of helping patients suffering from peanut allergy."

Viaskin Peanut previously received Breakthrough and Fast Track Designation from the FDA in 2015 and 2012, respectively. The BLA for Viaskin Peanut is supported by a global development program comprised of seven clinical trials. Data from Phase III studies, PEPITES and REALISE, which studied patients four to 11 years of age for 12 months, as well as supportive long-term data from the Company's open-label Phase II program, were included in this submission.

Dr. Hugh Sampson, Chief Scientific Officer of DBV Technologies and Kurt Hirschhorn Professor of Pediatrics at the Icahn School of Medicine at Mount Sinai said, "We believe that the safety and efficacy data generated in our clinical trials support our mission to potentially offer EPIT, a proprietary desensitization treatment, to peanut-allergic children in an easy and convenient manner for families."
