DBV Technologies to Highlight New Clinical Data at ACAAI 2022

DBV Technologies, following the conclusion of the meeting for those who are unable to attend. DBV will also host a booth in the ACAAI Exhibit Hall from Friday, November 11, through Sunday, November 13.

This year's meeting will also feature a "Product Theater" on the Evolution of the Prevention and Treatment of Peanut Allergy in Young Children. Professors Gideon Lack, M.D., and J. Andrew Bird, M.D., will engage in a lively discussion around how evidence from peanut allergy prevention and treatment studies in young children may impact current and future clinical practice. The Product Theater is scheduled for Saturday, November 12, from 9:35 a.m. to 10:00 a.m. EST in the Exhibit Hall, Upper Concourse.

DBV is the sole sponsor, via an independent educational grant, of the International Food Allergy Symposium, a full-day symposium that kicks off ACAAI. Leading experts from around the world will present various topics related to food allergy, including epidemiology, diagnostics, prevention and treatment. The symposium is scheduled for Thursday, November 10, from 8:00 a.m. to 6:00 p.m. EST. The Company is also sponsoring the 31st Annual FIT Bowl, a game show-type competition that tests the knowledge of participating teams from training programs around the country. The competition is set to be held on Saturday, November 12, from 5:30 p.m. to 7:30 p.m. EST in Commonwealth Ballroom Salons 1 & 2.

"There is a significant unmet need that persists among toddlers suffering from peanut allergy. The additional data being presented at this year's ACAAI meeting highlight the potential for Viaskin Peanut as a treatment option for this young and vulnerable patient population if approved," said Dr. Pharis Mohideen, Chief Medical Officer of DBV Technologies. "We continue to work towards seeking approval to bring this novel treatment option to market as expeditiously as possible."

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. The safety and efficacy of Viaskin Peanut have not yet been established by the U.S. Food and Drug Administration or the European Medicines Agency. Viaskin is DBV's proprietary approach to epicutaneous immunotherapy (EPIT), a method of delivering biologically active compounds to the immune system through the skin.
