DBV Technologies Provides Update on Regulatory Progress for Viaskin Peanut

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT) today announced that the U.S. Food and Drug Administration (FDA) has agreed that the available efficacy and safety data for Viaskin Peanut supports the submission of a Biologics License Application (BLA) for the treatment of peanut allergy in children four to 11 years of age.

The FDA provided written responses to the clinical pre-BLA meeting package submitted by the Company, which reflect agreement on the content of the clinical module of the BLA for Viaskin Peanut. DBV remains on track to submit its BLA in the second half of 2018.

“We are pleased with this positive step forward in our progress towards potential approval of Viaskin Peanut, and appreciate the feedback we received from the FDA supporting submission of our BLA,” said Dr.  Pierre-Henri Benhamou , Chairman & Chief Executive Officer of DBV Technologies . “There are approximately one million children in the U.S. diagnosed with this life-threatening disease, and we look forward to continue working with the agency to address this urgent unmet medical need.”
