NCT04520594

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Increased potential of butyrate production following the use of individualized resistant starch, as assessed by meta-omics analysis.

    6 ± 1 months

  • Sustained potential for butyrate production following 6 months use of individualized resistant starch post randomization as assessed by meta-omics analysis.

    12 ± 2 months

  • Change in microbiome composition of cases towards the microbiome of controls as assessed by meta-omics analysis.

    6 ± 1 months and 12 ± 2 months

Secondary Outcomes (7)

  • Changes in patient reported disability outcomes as measured by the IBD Disability Index Questionnaire.

    Enrollment, 3 ± 1 months, 6 ± 1 months , 9 ± 1 months and 12 ± 2 months

  • Changes in patient, parent/caregiver reported quality of life outcomes as measured by the IMPACT III Questionnaires.

    Enrollment, 3 ± 1 months, 6 ± 1 months , 9 ± 1 months and 12 ± 2 months

  • Changes in intestinal mucosal inflammation by measuring fecal calprotectin through stool samples.

    Enrollment, 3 ± 1 months, 6 ± 1 months, 9 ± 1 months, and 12 ± 2 months

  • Change in clinical disease activity as measured by the wPCDAI for Crohn's Disease.

    Enrollment, 3 ± 1 months, 6 ± 1 months , 9 ± 1 months and 12 ± 2 months

  • Change in clinical disease activity as measured by the PUCAI for Ulcerative Colitis.

    Enrollment, 3 ± 1 months, 6 ± 1 months , 9 ± 1 months and 12 ± 2 months

  • +2 more secondary outcomes

Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • 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.

You may not qualify if:

  • 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.

Masking Details
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.
