Pinpoint Trial: Prebiotics IN Peanut Oral ImmunoTherapy
A Phase 1/2 study testing Prebiotic in people with Peanut Allergy, run by University of Chicago at 2 sites in United States.
Trial summary
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. Read more about this study

About this study
Official title: Fiber Supplementation In Children With Peanut Allergy On Oral Immunotherapy: A Randomized Controlled Pilot Study
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PrebioticDrug
A prebiotic is a purified fiber of plant origin that has digestive health benefits by fostering the growth of beneficial microbes.
PlaceboDrug
A placebo is a substance that has no therapeutic effects used as a control while testing new drugs.
| Study group | Role | What they receive |
|---|---|---|
| Treatment Group | Experimental | 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. Receives: Drug: Prebiotic |
| Control Group | Placebo comparator | 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. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
The Proportion of Subjects Mildly Symptomatic or Less at the 12 Month DBPCFC
To determine the proportion of subjects who met the primary endpoint by tolerating at least 2044 mg cumulative peanut protein with no more than mild symptoms during the 12-month DBPCFC.
Measured: At the exit double-blind placebo-controlled food challenge (approximately 13 months after enrollment).
Secondary outcomes (2)
The Proportion of Subjects Who Experience Dose Related GI Side Effects During Oral Immunotherapy
- To determine the proportion of subjects who experience dose related GI side effects during oral immunotherapy.
Measured: From first study intervention through the final exit food challenge visit, up to 15 months.
The Proportion of Subjects Who Experience Hypersensitivity Reactions (Other Than GI) During Oral Immunotherapy
- To determine the proportion of subjects who experience hypersensitivity reactions (other than GI) during oral immunotherapy
Measured: From first study intervention through the final exit food challenge visit, up to 15 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Prebiotic in people with Peanut Allergy, run by University of Chicago at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
