This year's meeting will also feature a "Product Theater" on Individualizing Peanut Allergy Management: A Case-based Panel Discussion. Drs. Douglas Mack, David Stukus, and Julie Wang will engage in a discussion around the factors influencing peanut allergy management, such as use of food challenges and effects of comorbidities, using various patient scenarios. The Product Theater is scheduled for Saturday, November 11, from 11:35 a.m. to 1:00 p.m. PST.
DBV is sponsoring the 32(nd) Annual FIT Bowl, a game show-type competition that tests allergy, asthma, and immunology knowledge of participating teams from training programs around the country.

"We are very pleased to have a significant presence at ACAAI again this year and
add to the growing body of data on the potential of Viaskin Peanut as a new treatment option for peanut-allergic toddlers," said Dr. Pharis Mohideen, Chief Medical Officer of DBV Technologies. "With no FDA approved treatments, toddlers and their families must practice avoidance, which can be stressful and can significantly impact quality of life. Our goal is to complete the remaining regulatory steps in support of a Biologics License Application (BLA) as quickly and efficiently as possible to potentially bring this novel treatment to these patients in need."
