Optimal Fecal Microbiota Transplant Dosing for Mild to Moderate Ulcerative Colitis
Phase 1
Completed
- Conditions
- Ulcerative Colitis
- Interventions
- Biological: Fecal Microbiota Transplantation (FMT), OpenBiomeOther: pretreatment antibiotics
- Registration Number
- NCT03006809
- Lead Sponsor
- Najwa Elnachef
- Brief Summary
This is a prospective unblinded, randomized trial for the use of Fecal Microbiota Transplantation (FMT) for the treatment of Ulcerative Colitis (UC), in combination with or without antibiotic pretreatment.
- Detailed Description
This is a prospective open-label, randomized trial for the use of Fecal Microbiota Transplantation (FMT) for the treatment of Ulcerative Colitis (UC), in combination with or without antibiotic pretreatment.
This trial involves 11 study visits at UCSF in San Francisco, CA.
The routes of administration will be via colonoscopy for all subjects with maintenance therapy administered orally (i.e. using encapsulated FMT) for half of the subjects and per rectum by enema in the other half of the subjects. Additionally, the utility of pretreatment antibiotics will be assessed.

- Simultaneous participation in another interventional clinical trial
- Patients who are pregnant, breast feeding or planning pregnancy during study trial period.
- During the trial period until one week after the trial end: Non-use of appropriate contraceptives in females of childbearing potential (e.g. condoms, intrauterine device (IUD), hormonal contraception, or other means considered adequate by the responsible investigator) or in males with a child-fathering potential (condoms, or other means considered adequate by the responsible investigator during treatment) or well-founded doubt about the patient's cooperation
- Patients with any other significant medical condition that could confound or interfere with evaluation of safety, tolerability or prevent compliance with the study protocol at the discretion of the investigator
- Life expectancy <6 months

- Primary Outcome Measures
Name Time Method The occurrence of a Serious Adverse event (SAE), solicited and unsolicited AE, new gastrointestinal medical condition and diagnoses from FMT treatment or new infection from FMT treatment up to 1 year safety endpoint
Steroid-free Clinical Remission at week 9 + endoscopic remission or response defined as total Mayo score ≤ 2 with all four sub-scores ≤ 1 and a ≥ 1 point reduction in endoscopy sub-score 8 weeks post initial treatment
- Secondary Outcome Measures
Name Time Method Progression of disease defined by increase in dosages of current UC medications 2, 4 and 8 weeks post initial FMT Time to death secondary to UC up to one year post initial FMT Changes in microbiome with FMT therapy.
