Trial summary

The exact origin of inflammatory bowel disease (IBD) is still unknown. The current hypothesis is that IBD is secondary to an abnormal intestinal immun response directed to all or part of the intestinal flora in genetically predisposed individuals. Read more about this study

About this study

Official title: Characterization of Mesenchymal Stem Cells From the Colon and Small Intestine of Patients With Inflammatory Bowel Disease - The COSMIC Study

The exact origin of inflammatory bowel disease (IBD) is still unknown. The current hypothesis is that IBD is secondary to an abnormal intestinal immun response directed to all or part of the intestinal flora in genetically predisposed individuals. Several experimental studies have demonstrated the ability of mesenchymal stem cells (MSCs) from bone marrow or adipose tissue origin to control intestinal inflammation in animal models. However, to date, there are no data regarding the functions of resident MSCs in the colon and small intestine of IBD patients. We hypothesize that dysfunction of resident intestinal MSCs contributes to the disruption of intestinal homeostasis in patients with IBD causing the development of intestinal inflammation. The aim of this research project is to identify, describe and characterize at the molecular and functional level MSCs of the colon and small intestine of patients with Crohn's disease and ulcerative colitis and to compare them with a control population.

Read the detailed description

Primary and secondary objectives:

Main Objective: Characterize morphologically, molecularly and functionally the MSCs of colon and small intestine of patients with IBD and compared to MSCs of colon and small intestine of control patients.

Secondary objectives: To study the reaction of colon and small intestine MHC in patients with IBD following stimulation with bacterial compounds.

Methodology:

Clinical study exploratory translational physiopathological. Two groups of patients with Crohn's disease and ulcerative colitis who require colonoscopy or surgery for intestinal resection will be included. These two groups will be compared to a control group consisting of patients requiring colonoscopy for screening or intestinal resection for colorectal cancer or diverticulum.

Intestinal sampling by biopsy during the colonoscopy or with surgical specimen during the surgery will be performed to isolate the MSCs.

The outcome measures will be a qualitative and quantitative analysis of MSCs by immunohistochemistry, immunofluorescence, cell proliferation and differentiation, production of pro- and anti-inflammatory cytokines in the basal state and after bacterial stimulation.

Total of 60 patients (20 in groups, 15 with colonoscopy and 5 with surgical specimens).

Questions about this trial

What is this clinical trial studying?

A study testing Intestinal biopsies during colonoscopy and Biopsies taken on surgical specimen in people with Inflammatory Bowel Diseases, run by University Hospital, Montpellier at 1 site in France.

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 11 inclusion and 10 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: stopped early, as of the sponsor's last update on 28 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: end of inclusion period and recruitment difficulties). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proliferation and differentiation of intestinal MSCs in IBD patients. (time frame: 1 month). 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 28 Dec 2021.
