Study summary

Ulcerative colitis (UC) is a chronic inflammatory disease of the colon characterized by superficial mucosal inflammation. Treatment aims to achieve and maintain remission, improve quality of life, and minimize complications. Advanced therapies, including biologics and small molecules, have significantly improved UC management by targeting specific inflammatory pathways. However, due to the multifactorial nature of UC-driven by genetic, environmental, and microbial factors-many patients do not achieve sustained remission, highlighting a therapeutic ceiling. Gut microbial dysbiosis and immune dysregulation are central to UC pathogenesis, with diet playing a critical role in influencing the gut microbiome. While biologics and small molecules have limitations, innovative approaches like combining fecal microbiota transplantation (FMT) and dietary interventions with advanced therapies show promise. FMT restores microbial balance, modulates immunity, and reduces inflammation, while dietary modifications, such as anti-inflammatory diets, enhance FMT efficacy by creating a favorable environment for donor microbiota engraftment. The present study is designed to evaluate the efficacy of three different microbiome manipulation strategies- FMT, AID and FMT + AID in combination with advanced therapies in patients with active UC in a 2X2 factorial trial design. Patients would be randomized into four different arms: FMT, AID, FMT+AID and placebo. The advanced therapies (biologics or small molecules) would be given in all four arms as standard therapy. With this design the trial would answer two important questions: a) efficacy of combination treatment with advanced therapies and microbiome manipulation strategies in active UC, and b) comparative efficacy of different microbiome manipulation strategies.

Read the detailed description

This study is a multicenter, randomized, factorial-design, double-blind, controlled trial investigating the effects of fecal microbiota transplantation (FMT) and dietary interventions in patients with mild to moderate, treatment-naïve, active inflammatory bowel disease. The trial is being conducted across multiple clinical centers, with a central microbiome analysis facility.

Randomization and Blinding:

Randomization: Centralized, computerized randomization is employed to ensure balanced treatment allocation. The permuted block method, along with stratification based on disease characteristics, ensures equal distribution across intervention arms Blinding: Patients, investigators collecting clinical data, and endoscopic video assessors are blinded to treatment allocation. The dietitian and endoscopist performing FMT (or sham FMT) are unblinded

Intervention Arms:

Participants are assigned to one of four treatment arms:

FMT + Anti-inflammatory Diet (AID) +Advanced therapy FMT + Sham Diet+ Advanced therapy Sham FMT + AID+ Advanced therapy Sham FMT + Sham Diet+ Advanced therapy FMT is administered via colonoscopy at 0, 2, and 6 weeks, with responders receiving maintenance doses every 8 weeks until week 48

Participant Timeline and Assessments:

Baseline Assessments: Clinical, laboratory, and endoscopic evaluations, including serological tests, inflammatory markers, and microbiome profiling.

Follow-up Schedule: Visits occur at Week 0, Week 6, Week 10, and then every 8 weeks until Week 48.

Endoscopic Monitoring: Colonoscopy is performed at baseline, Week 10, and Week 48. Centralized endoscopic video scoring ensures consistency

Data Collection and Management:

Paper CRF's and Electronic Data: The paper based CRF's will be filled first and then data will be entered into a REDCap software.

Dietary Monitoring: Participants will use the IBD NutriCare mobile application for diet tracking.

Microbiome Analysis: Fecal samples are processed and analyzed at a designated microbiome research center.

Safety Monitoring and Compliance:

Adverse Event Reporting: All safety events, including potential serious adverse events (SAEs), are logged and monitored by the Data and Safety Monitoring Board (DSMB).

Protocol Deviations: Documented and assessed for impact on trial integrity. Training and Quality Control: Regular site training ensures adherence to the protocol, and periodic audits maintain data quality

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2025 (actual). Primary completion is estimated for Mar 2027, 24 months after the start.

Of 225 non-industry interventional studies with no phase under Colitis, Ulcerative, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 56. This study's planned 24 months is below that.

Counting every sponsor, half of 236 studies reached it within 34 months; a quarter within 16 and three quarters within 54.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 2, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
