DBV Technologies to Participate in Upcoming EAACI Congress 2025

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT – CUSIP: 23306J309), a clinical-stage biopharmaceutical company, today announced upcoming participation in the European Academy of Allergy and Clinical Immunology (EAACI) Congress, June 13 – 16, 2025, in Glasgow, United Kingdom. DBV will present two posters and will also host a symposium and exhibit booth in the EAACI exhibit hall.

Data to be presented during the scientific sessions will describe the reduced rate of reactions from accidental peanut consumption (APC) with the VIASKIN® peanut patch versus placebo in Year 2 of the Company’s EPITOPE open-label extension (OLE) trial, as well as data from the Company’s Phase 2 study (APTITUDE), which was conducted in collaboration with Nestlé Health Science¹, to evaluate the sensitivity, specificity and safety of a VIASKIN® patch (DBV1605), for the diagnosis of non-IgE mediated cow’s milk allergy in infants (>28 days old and ≤24 months).

“We are delighted to present the latest science on our VIASKIN® patch platform at this year’s EAACI conference, which is among the most prestigious and widely attended gatherings of allergy experts and thought leaders from around the world,” said Daniel Tassé, Chief Executive Officer, DBV Technologies. “Notably, our symposium will offer new insights into epicutaneous immunotherapy for peanut allergy, including a dynamic discussion describing the clinical relationship between the allergist and the patient. We are confident that our presentations at this year’s EAACI conference will further advance our collective understanding of epicutaneous immunotherapy as an exciting potential new therapeutic option for food allergy.”

DBV’s symposium, “Peanut Allergy: Recent Research Highlights”, will be co-chaired by Prof Gideon Lack, Professor of Pediatric Allergy, London Allergy Care and Knowledge and Prof Alexandra Santos, Professor of Pediatric Allergy, King’s College London and Honorary Consultant in Pediatric Allergy at the Evelina London Children’s Hospital. The symposium will include lectures on the food-allergic patient/allergist clinical relationship by Ozlem Ceylan, Chair of EAACI Patient Organization Committee (for the patient’s perspective) and Prof Sophia Tsabouri, University Hospital of Ioannina, Greece, and Chair of the EAACI Pediatric Section (for the allergist’s perspective) , as well as a presentation from Prof Katharina Blümchen, University Hospital Frankfurt, Germany, who will describe new clinical data on epicutaneous immunotherapy for peanut allergy.

“We look forward to sharing new clinical data from year two of the EPITOPE open label extension highlighting real-world protective effects of the VIASKIN® Peanut patch in peanut-allergic toddlers,” said Dr. Pharis Mohideen, Chief Medical Officer, DBV Technologies. “These data build upon results that were shared at EAACI 2024 and demonstrate further reductions in APC-related reactions with increased time on treatment. These results from Year 2 of the EPITOPE open label extension suggest the potential of VIASKIN® Peanut patch, if approved, to mitigate reactions due to APCs, which we know are common, despite families practicing strict avoidance. We also look forward to sharing the results from the APTITUDE study, which, despite its early termination due to enrollment difficulties in this patient population and not as a result of any safety issues, are nonetheless an encouraging step forward in demonstrating the broad potential of the VIASKIN® patch in food allergy.”

About DBV Technologies
DBV Technologies is a clinical-stage biopharmaceutical company developing treatment options for food allergies and other immunologic conditions with significant unmet medical need. DBV is currently focused on investigating the use of its proprietary VIASKIN® patch technology to address food allergies, which are caused by a hypersensitive immune reaction and characterized by a range of symptoms varying in severity from mild to life-threatening anaphylaxis. Millions of people live with food allergies, including young children. Through epicutaneous immunotherapy (EPIT™), the VIASKIN® patch is designed to introduce microgram amounts of a biologically active compound to the immune system through intact skin. EPIT is a new class of non-invasive treatment that seeks to modify an individual’s underlying allergy by re-educating the immune system to become desensitized to allergen by leveraging the skin’s immune tolerizing properties. DBV is committed to transforming the care of food allergic people. The Company’s food allergy programs include ongoing clinical trials of VIASKIN Peanut in peanut allergic toddlers (1 through 3 years of age) and children (4 through 7 years of age).

DBV Technologies is headquartered in Châtillon, France, with North American operations in Warren, NJ. The Company’s ordinary shares are traded on segment B of Euronext Paris (Ticker: DBV, ISIN code: FR0010417345) and the Company’s ADSs (each representing five ordinary shares) are traded on the Nasdaq Capital Market (Ticker: DBVT; CUSIP: 23306J309).
