Press Release

Montrouge, France, December 4, 2017

DBV Technologies CEO, Chairman, and Co-Founder, Dr. Pierre-Henri Benhamou Recognized for His Lasting Impact on the Food Allergy Community and Research Advancement by FARE (Food Allergy Research & Education)

DBV Technologies (Euronext: DBV—ISIN: FR0010417345—Nasdaq Stock Market: DBVT) – Chief Executive Officer, Chairman, and Co-Founder of DBV Technologies, Dr. Pierre-Henri Benhamou, will be honored at the 20^th Anniversary Food Allergy Ball Benefiting Food Allergy Research & Education (FARE) as one of the “20 for 20” 2017 recipients. This prestigious recognition pays tribute to 20 leaders who have made a lasting impact on the food allergy community over the past two decades.

A former pediatrician with a lifelong passion for science and entrepreneurship, Dr. Benhamou co-founded DBV Technologies in 2002 after understanding first-hand the critical need for safe and effective medicines to treat the increasing number of patients suffering from food allergies. In collaboration with a team of top scientists and clinicians, Dr. Benhamou has led the development and patenting of EPIT^®, or epicutaneous immunotherapy, DBV’s proprietary and novel method of allergen immunotherapy. EPIT aims to deliver biologically active compounds to the immune system through intact skin using the Viaskin platform.

Over the last 15 years, DBV Technologies has been at the forefront of research and development efforts advancing food allergy treatments, including developing Viaskin Peanut, the first investigational treatment for peanut-allergic children to receive Fast Track and Breakthrough Therapy designations from the U.S. Food and Drug Administration (FDA). DBV plans to present full study results from its Phase III trials of Viaskin Peanut in children four to 11 years of age at major medical meetings in 2018, as well as continue regulatory discussions in the United States, Europe and other countries for the potential use of Viaskin Peanut in this patient population. In addition to advancing Viaskin Peanut, DBV is also conducting an ongoing Phase IIb trial of Viaskin Milk, the most advanced product candidate in development for the treatment of cow’s milk protein allergy (CMPA), in patients two to 17 years of age.

“FARE has been a positive catalyst for progress and innovation in the field of food allergies, and a vital partner in the advancement of clinical research. I am deeply honored to be among the leaders who are receiving this special recognition from FARE. Whether we are in pharmaceuticals, academia, or the non-profit arena, we share a common mission: to address the unmet needs for food-allergic patients,” said Dr. Benhamou. “We are proud of our clinical trials exploring a new class immunotherapy to potentially treat patients with food allergies, and remain hopeful that our efforts will lead to transforming the lives of these patients and their caretakers.”

FARE will hold the 20^th Anniversary of the Food Allergy Ball on Monday, December 4, 2017 at The Pierre in New York City. The 2017 “20 for 20” commemorates the 20^th anniversary of this event. All proceeds will benefit FARE, a national nonprofit organization with the mission of improving the quality of life and the health of individuals with food allergies, and providing them hope through the promise of new treatments.
