Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine if a plant-based resistant starch that is optimized for the individual will target the underlying cause of inflammatory bowel disease and restore a "healthier" gut microbiome in pediatric participants with inflammatory bowel disease.

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
Unblinding will occur only if necessary to ensure study participants safety, interim analysis at 5 ± 1 months, or eligibility for our associated open label trail (OARS trial). Only Dr. Mack (Co-PI) can request to break the blind for safety reasons or eligibility for the OARS Trial; only Dr. Stintzi (Co-PI) will request to break the blind for interim analysis. Once the blind is broken, the patient will be discontinued from study product.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Capable of giving informed consent, or if appropriate, have an acceptable representative capable of giving consent on the participant's behalf.
* Enrolled in the main parent study.
* Existing Crohn's disease or ulcerative colitis diagnosis.
* In clinical remission or with mild disease (wPCDAI of 0-39.5 for CD; PUCAI of 0-30 for UC) with no changes in standard of care treatment for the previous month and without anticipated changes for the next month.
* Ability and willingness to comply with study procedures (e.g. stool collections) for the entire length of the study.
* Willing to provide consent/assent for the collection of stool samples.

Exclusion Criteria

* Allergy to resistant starch or excipients.
* Co-existing diagnosis with diabetes mellitus.
* Treatment with another investigational drug or intervention throughout the study.
* Current drug or alcohol dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
* Inability or unwillingness of an individual or legal guardian to give written informed consent.
* Concomitant chronic disease requiring medications.
* Requirement for antibiotic therapy \>2 weeks duration.
* Participant's microbiota does not respond to any of the resistant starch from the assembled panel as measured through the RapidAIM evaluation following the initial stool sample collection.
* Patients with previous intestinal surgery.
