Trial summary

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition of the intestine, which results in diarrhea, rectal bleeding, urgency, weight loss and abdominal pain.

About this study

Official title: A Prospective Longitudinal Study of Fecal Microbiome and Calprotectin to Predict Relapse in Patients With Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition of the intestine, which results in diarrhea, rectal bleeding, urgency, weight loss and abdominal pain. The natural course of IBD is characterized by activity outbreaks and periods of remission. In most cases, relapses in Crohn's disease (CD) and in ulcerative colitis (UC) are unpredictable and despite effective medical treatment, a degree of subclinical inflammation may persist in the bowel wall, contributing to a significant risk of relapse.

In IBD, altered fecal microbiota signatures have been consistently reported which included a reduction in biodiversity with lower proportions of Firmicutes and increases in Proteobacteria and Bacteroidetes phylum members.

It is however unclear whether changes in microbial profile including diversity and composition can predict disease relapse in IBD. We hypothesize that fecal microbial signatures in conjunction with fecal calprotectin may play a role in predicting relapse in IBD patients.

Inflammatory bowel disease (IBD) is a chronic idiopathic inflammatory condition of the intestine, which results in diarrhea, rectal bleeding, urgency, weight loss and abdominal pain. The natural course of IBD is characterized by activity outbreaks and periods of remission. In most cases, relapses in Crohn's disease (CD) and in ulcerative colitis (UC) are unpredictable and despite effective medical treatment, a degree of subclinical inflammation may persist in the bowel wall, contributing to a significant risk of relapse.

Endoscopy has been used to monitor a disease but it is time-consuming, costly, invasive, and associated with certain risks of morbidity. Many patients are reluctant to undergo repeated endoscopic examinations, particularly when their disease is quiescent. Acute phase reactants have been used but their sensitivity and specificity in correlating to intestinal inflammatory activity are very low, and their capacity to predict disease relapse is poor and controversial. A number of fecal biomarkers have been evaluated for their utility for monitoring and predicting relapse in IBD but some of these biomarkers are also not specific.

In IBD, altered fecal microbiota signatures have been consistently reported which included a reduction in biodiversity with lower proportions of Firmicutes and increases in Proteobacteria and Bacteroidetes phylum members. In addition, disease remission and relapse are associated with microbial changes in both mucosal and fecal samples. In particular, a loss of species richness in Crohn's disease has been widely observed. Recently microbial biomarkers may differentiate between CD and UC. Furthermore, different microbial groups are associated with smoking habit and localization of the disease in CD and UC. It is however unclear whether changes in microbial profile including diversity and composition can predict disease relapse in IBD. We hypothesize that fecal microbial signatures in conjunction with fecal calprotectin may play a role in predicting relapse in IBD patients.

What is being measured

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

  1. Clinical relapse for CD patients

    Defined as worsening of the symptoms, accompanied by HBI score of ≥ 8 points for CD and require a change in therapy.

    Measured: 2 years

  2. Clinical relapse for UC patients

    Defined as partial Mayo score of ≥ 5 points for UC and require a change in therapy.

    Measured: 2 years

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 14 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 6 Sep 2019. 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 Hong Kong. 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?

Results are not available in the source record.

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

Contact Jessica Ching (+852 35053524, jessicaching@cuhk.edu.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical relapse for CD patients (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04079335, which also lists 6 linked publications.

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 6 Sep 2019.
