DBV Technologies to Highlight New Long-term Data from REALISE Trial at ACAAI 2021

DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT), a clinical-stage biopharmaceutical company, today announced that new clinical study results on the use of Viaskin™ Peanut (DBV712) 250 μg in children will be presented at the American College of Allergy, Asthma & Immunology (ACAAI) Annual Scientific Meeting, Nov. 4-8, 2021. Two abstracts have been accepted, including one oral presentation and one poster presentation. These presentations will be available on DBV’s website, www.dbv-technologies.com, following the conclusion of the meeting for those who are unable to attend. DBV will also host a booth in the ACAAI exhibit hall.

The data to be presented include new long-term results of the Phase 3 REALISE (REAL Life Use and Safety of EPIT™) study in children 4-11 years of age, including the safety of Viaskin Peanut over three years and potential impact on health-related quality of life (HRQL).

“These data presented at ACAAI contribute to our understanding of and excitement for the potential real-world use of Viaskin Peanut, if approved.” said Dr. Pharis Mohideen, Chief Medical Officer of DBV Technologies. “As we continue clinical development, we remain confident in the potential of Viaskin Peanut – and driven by the hope of bringing much needed treatment options to patients and their families.”

DBV is also sponsoring the 30th Annual FIT Bowl, a game show-type competition that tests the knowledge of participating teams from training programs around the country.

Viaskin Peanut is the Company’s lead product candidate designed to reduce the risk of allergic reactions due to accidental exposure to peanuts. An investigational non-invasive, once daily, epicutaneous patch, Viaskin Peanut seeks to deliver microgram quantities of peanut antigen to re-educate the immune system. Viaskin Peanut is DBV’s proprietary approach to epicutaneous immunotherapy (EPIT), a method of delivering biologically active compounds to the immune system through the skin.
