About Food Allergies

Food allergies represent an urgent and growing global unmet medical need. Approximately 15 million people in the United States and 17 million people in Europe have food allergies. Moreover, the prevalence of food allergies is increasing rapidly—in the United States, 1 in 25 children suffered from a food allergy a decade ago, compared to 1 in 13 today. For people living with food allergies, certain foods can cause severe allergic reactions, including potentially life-threatening anaphylaxis. There is no cure for food allergies. Currently, food-allergic patients manage their condition by strict allergen avoidance and carrying epinephrine auto-injectors for use in case of accidental exposure. Thus, in addition to the unmet medical need, food allergies can impose a significant quality of life burden. For more information, please visit and

ARC’s CODIT approach combines standardized, pharmaceutical-grade food allergens with controlled up-dosing protocols to desensitize patients and increase the thresholds at which they could experience allergic reactions.
