By doing this study, we hope to learn if using a dietary fiber called a prebiotic helps increase the number of children who can tolerate eating 1043mg of peanut protein (or about 3-4 peanuts) after going through oral immunotherapy (OIT) to peanut. We are also trying to determine if this fiber will reduce the side effects of OIT and if so, we would like to find out if the reason it is working is by changing the bacteria in the gut. Participation in this research will last about five years.
The purpose of this research is to gather information on the safety and efficacy of using a prebiotic as an adjunctive therapy to peanut oral immunotherapy. The prebiotic is not an FDA approved drug or medication rather a fiber found at local grocery stores.
