Trial summary

This study will test a newly developed dual modality probe, including optical coherence tomography (OCT) and angle-resolved low-coherence interferometry (a/LCI), in the human esophagus to determine 1) whether adequate tissue contact can be attained by the probe to acquire high quality images, and 2) to identify if… Read more about this study

About this study

Official title: Advanced Angle-Resolved Low Coherence Interferometry (a/LCI) Systems for Improved Clinical Utility: An a/LCI-Optical Coherence Tomography (OCT) Pilot Study

This study will test a newly developed dual modality probe, including optical coherence tomography (OCT) and angle-resolved low-coherence interferometry (a/LCI), in the human esophagus to determine 1) whether adequate tissue contact can be attained by the probe to acquire high quality images, and 2) to identify if these images can discern whether the imaged tissue is squamous or Barrett's Esophagus (BE) epithelium. This pilot study will test the operating characteristics of the probe and collect data for further optimization of the a/LCI-OCT device.

What participants receive

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

What is being measured

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

  1. Percentage of Correctly Identified Positive (Dysplastic) Biopsies

    Sensitivity of the a/LCI-OCT probe to detect dysplasia as measured by percentage of correctly identified positive biopsies. The a/LCI-OCT measurement of mean nuclear size was compared with a pre-determined threshold of mean nuclear size (11.84 microns from Terry et al study) to categorize biopsy samples as dysplastic or non-dysplastic.

    Measured: day 1

  2. Percentage of Correctly Identified Negative (Non-Dysplastic) Biopsies

    Specificity of the a/LCI-OCT probe to detect absence of dysplasia as measured by percentage of correctly identified negative biopsies. The a/LCI-OCT measurement of mean nuclear size was compared with a pre-determined threshold of mean nuclear size (11.84 microns from Terry et al study) to categorize biopsy samples as dysplastic or non-dysplastic.

    Measured: day 1

Secondary outcomes (1)
  1. Percentage of Participants With Adequate Tissue Contact to Acquire a High Quality Image

    percentage of participants that had adequate tissue contact to acquire high quality a/LCI-OCT images

    Measured: day 1

Questions about this trial

What is this clinical trial studying?

A study testing a/LCI-OCT imaging probe and esophageal biopsy in people with Barrett Esophagus, run by Duke University 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 7 inclusion and 3 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: finished, as of the sponsor's last update on 28 Nov 2023. 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?

Yes. Results are posted in the registry (first posted 28 Nov 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Correctly Identified Positive (Dysplastic) Biopsies (time frame: day 1). 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 NCT04392167, which also lists 1 linked publication.

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 Nov 2023; AzTrials last refreshed its copy on 1 Nov 2026.
