Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
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.
Experimental: Treatment Group
Subjects who meet inclusion criteria will be randomized 1:1. The treatment group will receive prebiotic therapy for 30 days, then subjects will start peanut oral immunotherapy (POIT) in addition to the prebiotic. Subjects will continue through a prescribed course of POIT for approximately 180 days. After completion of POIT up-dosing, subjects will continue on maintenance POIT plus prebiotic therapy for an additional 180 days at which time they will undergo a DBPCFC. Subjects will then stop prebiotic therapy and continue on maintenance POIT in extended observation for approximately 4 years.
Placebo Comparator: Control Group
Subjects who meet inclusion criteria will be randomized 1:1. The control group will receive placebo therapy for 30 days, then subjects will start peanut oral immunotherapy (POIT) in addition to the placebo. Subjects will continue through a prescribed course of POIT for approximately 180 days. After completion of POIT up-dosing, subjects will continue on maintenance POIT plus placebo for an additional 180 days at which time they will undergo a DBPCFC. Subjects will then stop placebo and continue on maintenance POIT in extended observation for approximately 4 years.
Drug: - Prebiotic
A prebiotic is a purified fiber of plant origin that has digestive health benefits by fostering the growth of beneficial microbes.
Drug: - Placebo
A placebo is a substance that has no therapeutic effects used as a control while testing new drugs.
