About this study

The overall aim of this research project is to evaluate the imaging performance of a confocal endomicroscope. Fluorescein, an FDA-approved topical fluorescent dye, will be used to provide topical mucosal contrast. The purpose of this instrument is to provide real-time endoscopic "histology" to guide endoscopic biopsy or endoscopic mucosal resection (EMR) in the patient study group. This endomicroscope probe will be used during colonoscopies in subjects with colonic dysplasia, known colonic adenomatous polyps scheduled for endoscopic resection, or suspected dysplasia in subjects with Inflammatory Bowel Disease (IBD).

Read the detailed description

The device is being tested in small groups of individuals: generally less than 10 for each of a variety of histologically different colonic lesions or diseases (eg. IBD, adenomas, sessile seriated adenomas (SSAs), hyperplastic polyps, normal tissue).

Being tested
confocal endomicroscope, Fluorescein
Medical subject headings
Adenomatous Polyps, Irritable Bowel Syndrome

What participants receive

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

  • confocal endomicroscopeDevice

    This instrument provides real-time endoscopic "histology" to guide endoscopic biopsy or endoscopic mucosal resection (EMR) in the patient study group during colonoscopies.

  • FluoresceinDrug

    Also called Fluorescite

    Fluorescent dye used for imaging contrast only.

Study groups in NCT03220711
Study groupRoleWhat they receive
Subjects with abnormal colon tissueExperimentalThe study subjects will be high-risk for colonic adenomas (i.e. strong family history of adenomas/adenocarcinoma or personal history of adenomas/adenocarcinoma), known adenoma scheduled for endoscopic resection, or in subjects with suspected dysplasia in inflammatory bowel disease (IBD). Fluorescein will be sprayed on the area of interest to provide imaging contrast for the images taken with the confocal endomicroscope.
Receives: Device: confocal endomicroscope; Drug: Fluorescein

What is being measured

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

  1. Depth-imaging capability of the confocal endomicroscope using an imaging contrast agent, fluorescein

    The test product efficacy will be assessed by evaluating the fluorescence intensities measured from suspicious regions of colonic mucosa where the agent is administered compared to adjacent normal mucosa.

    Measured: five minutes

Questions about this trial

What is this clinical trial studying?

A study testing confocal endomicroscope and Fluorescein in people with Colonic Dysplasia and Adenomatous Polyps, run by University of Michigan at 1 site in United States.

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 4 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: stopped early, as of the sponsor's last update on 22 Nov 2022. 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 United States. 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: Study terminated due to equipment breakage and lack of funding.). 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?

Depth-imaging capability of the confocal endomicroscope using an imaging contrast agent, fluorescein (time frame: five minutes). 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 22 Nov 2022.
