His experience and knowledge will be integral to getting INT301 into the hands of people suffering from peanut allergy in a timely manner.” About Peanut and Other Food AllergiesFood allergies affect more than 220 million people worldwide, including approximately 32 million people in the U.S. Management of food allergies currently focuses on avoidance of exposure to triggering foods, though often such foods, including peanuts, are common ingredients in food products and therefore difficult to avoid. Many people with peanut allergy are accidentally exposed and experience potentially life-threatening reactions, including anaphylaxis, each year. Unfortunately, food allergy remains an area of tremendous unmet medical need. About Oral Mucosal Immunotherapy™Oral mucosal immunotherapy (OMIT) uses a specially formulated toothpaste to stabilize and deliver allergenic proteins to immunologically active areas of the oral cavity with the greatest potential for allergy desensitization. Success with allergy immunotherapy hinges on consistent exposure of a patient’s immune system to gradually “desensitize” the patient to the specific allergy trigger over time. OMIT presents advantages over other approaches to allergy immunotherapy due to its targeted delivery and simplified administration, which supports the potential for improved adherence. About Intrommune TherapeuticsIntrommune, dedicated to improving and protecting the lives of people with food allergy, is developing the revolutionary oral mucosal immunotherapy (OMIT) treatment platform for food allergies. OMIT is a patient-friendly solution for over 220 million people worldwide, including 32 million people in the U.S., who suffer from life-altering food allergies. Intrommune Therapeutic’s lead product, INT301, has entered Phase 1 clinical trials. Phase 1, along with future studies, are intended to support the development of OMIT as a safe, effective and convenient therapy for patients who suffer from peanut allergy.
