About this study

Official title: A Phase 2 Randomized, Double-Blind, Placebo-Controlled Study to Confirm Efficacy and Safety of MH002 and to Assess the Effect of Dose in Patients With Mild-to- Moderate Ulcerative Colitis Insufficiently Controlled With 5-Aminosalicylic Acid

The main goal of the study is to check if MH002 works and is safe to use. In a previous study in 45 patients with Ulcerative Colitis, MH002 was found to have favorable effects. In this study, 2 different doses will be tested, and long-term treatment effects will be investigated.

MH002 is a live biotherapeutic product (LBP). This is a biological medicine containing live bacteria used to restore the normal function of a gut that is damaged by ulcerative colitis (UC). Ulcerative colitis is a bowel disease that causes inflammation and sores in the gut.

Being tested
Low-dose MH002, High-dose MH002, Placebo
Keywords
5-aminosalicylic-acid, live biotherapeutic product, ulcerative colitis
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Low-dose MH002Drug

    Microbiome-based live biotherapeutic product consisting of 6 wildtype commensal strains at a dose of 1 × 10^10 equivalent colony forming units [eqCFU]), administered orally (in a capsule) once daily

  • High-dose MH002Drug

    Microbiome-based live biotherapeutic product consisting of 6 wildtype commensal strains at a dose of 4 × 10^10 equivalent colony forming units [eqCFU]), administered orally (in a capsule) once daily

  • PlaceboDrug

    Blank placebo administered orally (in a capsule) once daily

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in centrally-assessed Mayo Endoscopic Subscore (MES) at Week 12.

    The MES ranges from 0 to 3, with higher scores indicating more severe disease.

    Measured: Week 12

Secondary outcomes (6)
  1. To confirm the efficacy of MH002 to induce clinical remission at Week 12

    Key secondary endpoint: Clinical remission is defined as a modified Mayo Score (mMS) ≤2, all mMS subscores ≤1, and an Rectal Bleeding (RB) subscore of 0, with endoscopic MES based on worst segment assessed by a blinded central reader, and 2-item Patient-Reported Outcome (PRO-2) scores computed from the e-diary data

    Measured: Week 12

  2. Change from baseline in histologic scores Robarts' Histopathology Index (RHI) at Week 12

    The RHI score ranges from 0 to 33, with higher scores indicating more severe disease activity.

    Measured: Week 12

  3. (Median) Percent change from baseline in fecal calprotectin (FC) at Week 12

    Measured: Week 12

  4. Change from baseline in UC-100 score at Week 12

    The UC-100 is a composite disease activity index consisting of clinical, endoscopic, and histological findings. The UC-100 score ranges from 1 to 100, with higher scores indicating more severe disease activity.

    Measured: Week 12

  5. Change from baseline in PRO-2 score at Week 12

    2-item Patient-Reported Outcome (PRO-2) scores computed from the e-diary data on stool frequency and rectal bleed. The PRO-2 score ranges from 0 to 6, with higher scores indicating more severe disease.

    Measured: Week 12

  6. To confirm the safety and tolerability of MH002 in the Induction Phase

    Incidence of Treatment-Emergent Adverse Events, Serious Adverse events Incidence of Treatment-emergent abnormalities in laboratory parameters and vital signs during 12 weeks treatment period.

    Measured: Up to Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Low-dose MH002 and High-dose MH002 in people with Colitis, Ulcerative, run by MRM Health NV at 49 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 21 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 49 sites in Ukraine, Georgia, Poland, Serbia, United States and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Els Callebaut (+32 9 277 08 50, clinicaltrials@mrmhealth.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in centrally-assessed Mayo Endoscopic Subscore (MES) at Week 12. (time frame: Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2026.
