DBV Technologies to Present Data on Epicutaneous Immunotherapy and Food Allergy Quality of Life at EAACI Digital Congress 2020

Virtual presentations will include data about children with and without multiple food allergies from the pivotal Phase III peanut allergy immunotherapy trial PEPITES

Biologics License Application for investigational Viaskin Peanut under review with U.S. Food and Drug Administration

DBV Technologies (Euronext: DBV - ISIN: FR0010417345 - Nasdaq Stock Market: DBVT), a clinical-stage biopharmaceutical company, today announced that seven abstracts, including four late breakers, highlighting new data from the Company's pre-clinical and clinical food allergy programs were accepted at the European Academy of Allergy & Clinical Immunology (EAACI) Digital Congress, June 6-8, 2020. The virtual oral and poster presentations will be available on the EAACI website to conference registrants starting Saturday, June 6 at 9:00am CEST / 3:00am EDT through December of this year.

"The data we are presenting at this year's digital EAACI congress highlight potential applications of epicutaneous immunotherapy across patient populations as well as new insights into promising cellular pathways for biomarker identification," said Pharis Mohideen, M.D., Chief Medical Officer of DBV Technologies. "These presentations highlight the breadth of research DBV is conducting on the science and impact of food allergy as part of our commitment to improving the lives of patients through innovative potential treatments like epicutaneous immunotherapy. Our lead candidate, Viaskin Peanut, is currently under FDA review, and we look forward to making this investigational therapy available for patients as soon as possible, if approved."

Viaskin Peanut is an investigational therapy which aims to deliver biologically active compounds to the immune system through the skin to potentially safeguard peanut-allergic children in the event of accidental exposure to peanut. The Viaskin Peanut Biologics License Application, which received Breakthrough (2015) and Fast Track (2012) designations by U.S. Food and Drug Administration (FDA), is currently under review with a target action date of August 5.
