About Aimmune Therapeutics

Aimmune Therapeutics, Inc., is a biopharmaceutical company developing
oral treatments for life-threatening food allergies. The company’s Characterized
Oral Desensitization
ImmunoTherapy
(CODIT™) approach is intended to provide meaningful levels of protection
against allergic reactions resulting from accidental exposure to food
allergens by desensitizing patients with defined, precise amounts of key
allergens. Aimmune’s first investigational biologic product, AR101, is
being developed as a treatment to reduce the risk of anaphylaxis
following accidental exposures to peanut. The BLA for AR101 is under
review by the FDA, which in 2015 granted AR101 Breakthrough Therapy
Designation for the desensitization of peanut-allergic patients 4 to 17
years of age. Aimmune expects to file for marketing approval of AR101 in
Europe in mid-2019. Aimmune has filed an IND application for its second
product, AR201 for the treatment of egg allergy, and intends to start a
randomized phase 2 clinical trial in mid-2019. For more information,
