Clinical Trial Summary

The primary aims of this phase I/II, randomized, placebo controlled study are the assessment of safety and tolerability of universal donor FMT compared to placebo in pediatric and young adult subjects (ages 5 years through 30 years) with active ulcerative colitis (UC) or active Crohn's colitis (CD) who have failed, are intolerant to, or have refused traditional first-line maintenance therapy. Secondary objectives include the identification biomarkers in both donor and recipient that may confer a clinical response and to establish whether or not ongoing FMT maintenance therapy is required for maintenance of clinical benefit in pediatric UC or pediatric CD.

Description:

This is a single-center pilot, phase I/II, randomized, prospective, double-blinded, placebo-controlled study of FMT in the treatment of active pediatric UC and active pediatric CD. The primary aim is to assess safety and feasibility of a weekly FMT maintenance therapy. A total of 10 patients with active UC (as defined by PUCAI score of >9) and 10 patients with active CD (as defined by PDCAI score of >10) will be enrolled and randomized to receive FMT or placebo-FMT (study treatment) by retention enema for 1 week and oral, frozen encapsulated inocula/placebo for 7 weeks. After the first 8 weeks, subjects on FMT who improve or subjects on placebo-FMT who do not improve will have the option to continue on study treatment or switch to open-label FMT until the end of 4 months from study initiation. Subjects will be followed by telephone to assess adverse events for a total of 6 months after their last FMT dose. An initial subset of no more than 20 subjects will be enrolled in the study (will be limited to only those patients 12 years of age or older and to those who have mild to moderate disease) and randomized to receive FMT or placebo. We'd expect short term adverse events to occur within 7 days of FMT administration. Individual subject safety data will be reviewed by the PI to assess whether FMT appears to be safe in the subject before continuing the subject towards open-label use of FMT. Patient metadata and stool samples will be collected at key time points. The patient-reported metadata collection technique will allow for numerous clinical correlations to be parsed out using the random forest machine learning capabilities of synthetic learning in microbial ecology (SLiME) to identify taxonomic features associated with important clinical parameters.

Eligibility

Male and female children and young adults, aged 5 years to 30 years, who meet the following inclusion criteria, will be enrolled in the study. Two initial subsets will be created: an initial subset of 20 subjects limited to patients greater than or equal to 12 years of age with mild to moderate ulcerative colitis (i.e., PUCAI < 65) patients with mild to moderate Crohn's disease (i.e., PDCAI less than or equal to 30).

All patients must satisfy below criteria:

1. Have UC (PUCAI >9) or CD (PDCAI >10) and have failed, are intolerant to, or have refused first-line maintenance therapy.

2. Have had visual or histologic evidence of inflammation confirmed through colonoscopy no more than 105 days prior to randomization.

3. Have negative test results for Hepatitis B (HBV), Hepatitis C (HCV), and Human Immunodeficiency Virus (HIV).

4. Have a negative urine hCG test if female of childbearing potential.

5. Able to swallow antibiotic, FMT or placebo capsules.

6. Able to give informed consent and/or assent as appropriate (patients 12-17 will be asked to provide written assent, patients 5-11 will be observed for assent or dissent behaviorally, or with verbal/written communication)

7. Willing and able to participate in the study requirements, including serial stool collection, survey completion and clinic visits.

8. Willing to undergo telephone follow-up to assess for safety and adverse events.

9. Must be free of any known food allergy.

10. Agrees and willing to have an enema for purposes of induction therapy. Patients who have disease that has required other medications (including steroids, immunosuppressives, and biologics) will be included. Exclusion Criteria: Subjects who fall into any of the following exclusion criteria at the time of screening are not eligible for enrollment into the study.

1. Patients with extensive and/or severe CD (i.e. fistulizing disease, abscess, small bowel obstruction, fevers).

2. Patients in a clinical remission (PUCAI < 9) or (PCDAI <10).

3. Patients with recent (within 4 weeks) dose change of biologics, 5-ASA, steroids or immunomodulators

4. Patients considered to have toxic megacolon.

5. Patients with a known drug allergy to vancomycin, metronidazole or polymyxin.

6. Patients with a history of aspiration, gastroparesis, surgery involving the upper gastrointestinal tract (that might affect upper gastrointestinal motility) or unable to swallow pills.

7. Patients with esophageal dysmotility or swallowing dysfunction.

8. Patients with known food allergies.

9. Patients with positive test results for HBV, HCV, or HIV.

10. Female patients with a positive test result on a urine hCG test.

11. Patients unwilling or unable to give consent or participate in all study requirements.

12. Patients unable or unwilling to receive a retention enema for purposes of induction therapy.

13. Patients with recent (within 6 weeks) systemic antibiotic use.

14. Patients who have testing consistent with active clostridium difficile.

15. Patients with known prior experience with donor FMT.

Intervention

Biological:
• Fecal Microbiota Transplant (FMT)
The study intervention consists of frozen, bottled or encapsulated fecal microbiota preparations that have been screened and prepared to a uniform and rigorous standard by OpenBiome. FMT is performed by patients receiving a retention enema and swallowing capsules, introducing stool from a healthy donor into their intestinal tract.
• Placebo
Placebo administration will consist of both a placebo retention enema and placebo capsules.
