Fecal Microbiota Transplantation in an Expanded Ulcerative Colitis Population

A Multi-centre, Randomised Controlled Trial Comparing Fecal Microbiota Transplantation to Placebo in an Expanded Ulcerative Colitis Population: a Feasibility Study (FRONTIER-UC)

Fecal Microbiota Transplantation in an Expanded Ulcerative Colitis Population (NCT07401680) is a Phase 1 interventional studying Ulcerative Colitis and Inflammatory Bowel Diseases, sponsored by University of Alberta. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This is a multi-centre, randomised controlled trial comparing fecal microbiota transplantation to placebo in an expanded ulcerative colitis population: a feasibility study (FRONTIER-UC) to determine whether a full-scale randomized controlled trial (RCT) to investigate fecal microbiota transplantation (FMT) in ulcerative colitis (UC) is feasible.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Ulcerative Colitis, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 85 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Ulcerative Colitis subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Bring the printable summary of this trial — including the NCT ID (NCT07401680), the sponsor (University of Alberta), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Frequently Asked Questions

What is the NCT07401680 clinical trial studying?

Who can participate in NCT07401680?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT07401680?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
