DBV Technologies Receives Complete Response Letter from FDA for Viaskin Peanut BLA in Children Ages 4-11 Years

DBV Technologies (Euronext: DBV - ISIN: FR0010417345 - Nasdaq Stock Market: DBVT), a clinical-stage biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter regarding the Companys Biologics License Application (BLA) for investigational Viaskin Peanut (DBV712), a non-invasive, once-daily epicutaneous patch to treat peanut allergies in children ages 4 to 11 years.

The Complete Response Letter indicates that the FDA cannot approve the application in its present form. The FDA has identified concerns regarding the impact of patch-site adhesion on efficacy and indicated the need for patch modifications, and subsequently a new human factor study. The FDA has also indicated that supplementary clinical data would need to be generated to support the modified patch. In addition, the FDA requested additional Chemistry, Manufacturing and Controls data. The Agency did not raise any safety concerns related to Viaskin Peanut.

DBV intends to request a meeting with FDA to discuss the FDAs comments as well as requirements for additional clinical data that may be needed to support BLA resubmission. The Company anticipates providing an update following this meeting, including updated cash runway resulting from the recent restructuring announced on June 26, 2020.

We are very disappointed in the FDAs response, but continue to believe in the potential of Viaskin Peanut. Peanut allergy is one of the most common food allergies, and accidental exposure can result in life threatening reactions, Daniel Tass, Chief Executive Officer of DBV Technologies, stated. We plan to fully collaborate with the FDA with regards to the outstanding issues and believe that the EPIT patch technology platform lends itself well to potential modifications to enhance patch functionality. We remain dedicated in our mission to develop innovative treatments for patients with food allergies.
