Study on Variation of Serum and Fecal Biomarkers After Treatment to Predict Mucosal Healing in Patients With Ulcerative Colitis (MIROIR)

June 16, 2026 updated by: University Hospital, Clermont-Ferrand
Mucosal healing is recognized hitherto as the best therapeutic endpoint in patients with Ulcerative Colitis (UC) but its use in daily practice is limited by the low acceptability of repeated colonoscopies. In this context, fecal biomarkers are attractive alternatives. Fecal calprotectin showed very good negative predictive value to eliminate IBD diagnosis, good correlation to endoscopic activity and good ability to predict relapse. Recently, several teams including ours, showed that fecal biomarkers such as Chitinase 3-Like 1 (CHI3L1), matrix metalloprotease type 9 (MMP-9) and serum biomarkers neutrophil gelatinase B- complex associated lipocalin (NGAL)-MMP9 and serum CHI3L1 could be better biomarkers than fecal calprotectin to assess endoscopic activity in patients with UC.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with UC requiring endoscopy (colonoscopy or recto sigmoidoscopy) in their management and with endoscopic activity (Mayo endoscopic score ≥ 2) will be offered inclusion in this study.

Blood and faecal samples will be taken in addition to the usual care measurements for the determination of biomarkers under study. Routine care biopsies will be performed in each patient during endoscopy to assess histologic activity.

Because of endoscopic activity, treatment will be changed (start, increase or change treatment) according to current recommendations. After several weeks of treatment (8 ± 4 weeks for 5-ASA and corticosteroids, 12 to 24 weeks for immunosuppressants and 12 ± 2 weeks for biotherapies), patients will have an evaluation performed by endoscopy (colonoscopy or rectosigmoidoscopy) with biopsies for histological analysis (routine care). Blood and faecal samples will be taken in addition to the usual care measurements (blood count, albumin, CRP and faecal calprotectin...) for the determination of biomarkers under study.

Every patient will have a follow-up every 3 months for 1 year with clinical evaluation, blood and faecal biomarker assays and each patient will have a new endoscopic evaluation with biopsies for histological analysis at 12 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
