DBV Technologies is focusing on food allergies, including milk and peanut, for which there are currently no effective treatments. DBV Technologies has designed two product candidates: Viaskin® Peanut and Viaskin® Milk. Viaskin® Peanut for use in children has received Fast Track designation and Breakthrough Therapy designation from the U.S. Food and Drug Administration.
