Specially formulated toothpaste developed for desensitizing adults with peanut allergies

Researchers have found in a new study that Oral mucosal immunotherapy (OMIT), delivered as a specially formulated toothpaste is safe and convenient option for desensitizing adults with peanut allergies.
The study was presented at the annual meeting of the American College of Allergy, Asthma & Immunology, held from Nov. 9 to 13 in Anaheim, California.
“OMIT uses a specially formulated toothpaste to deliver allergenic peanut proteins to areas of the oral cavity,” says allergist William Berger, MD, ACAAI member and author of the study. “OMIT as a delivery mechanism for peanut protein has great potential for food allergy desensitization. Due to its targeted delivery and simple administration, it supports the goal of improved adherence.”
This study enrolled 32 adults, age 18-55, with peanut allergy in a 3:1 ratio of active treatment to placebo control. Participants received either an escalating dose of peanut toothpaste or placebo. During this 48-week trial, safety was monitored during the up-dosing and maintenance phases. Exploratory biomarkers were also evaluated, and oral food challenges were conducted. (Exploratory biomarkers are blood tests used to show if a person’s immune system is responding to treatment with an allergen such as peanut.)
