About this study

This study is to identify potential biomarkers for the early detection of Barrett's Esophagus, esophageal carcinoma (both adenocarcinoma and squamous cell carcinoma), and gastric cancer via sponge cytology.

Read the detailed description

This study is to identify potential biomarkers for the early detection of Barrett's Esophagus, esophageal carcinoma (both adenocarcinoma and squamous cell carcinoma). Esophageal and gastric cytology will be collected via sponge capsule. Candidate genes will be tested with DNA isolated from these samples in order to identify optimal biomarkers to differentiate between Barrett's esophagus and esophageal/gastric cancer versus normal esophageal/gastric tissue.

What is being measured

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

  1. Difference in methylation of gene markers to discriminate Barrett's esophagus from non-pathological esophageal squamous and gastric cardia tissue.

    Using DNA methylation, we plan on identifying, from a pool of highly selected marker candidates, the best biomarkers that are aberrantly methylated in Barrett's esophagus versus control in order to differentiate between subjects who have Barrett's esophagus and those who do not have Barrett's esophagus. This is measure using methylation index and the calculated probability score from different methylation index values.

    Measured: 1 day

  2. Difference in methylation of gene markers to discriminate esophageal carcinoma from non-pathological esophageal squamous and gastric cardia tissue.

    Using DNA methylation, we plan on identifying, from a pool of highly selected marker candidates, the best biomarkers that are aberrantly methylated in esophageal cancer versus control in order to differentiate between subjects who have esophageal cancer and those who do not. This is measure using methylation index and the calculated probability score from different methylation index values.

    Measured: 1 day

  3. Difference in methylation of gene markers to discriminate gastric cancer from non-pathological esophageal squamous and gastric cardia tissue.

    Using DNA methylation, we plan on identifying, from a pool of highly selected marker candidates, the best biomarkers that are aberrantly methylated in gastric cancer versus control in order to differentiate between subjects who have gastric cancer and those who do not. This is measure using methylation index and the calculated probability score from different methylation index values.

    Measured: 1 day

Secondary outcomes (10)
  1. Sensitivity of candidate biomarker p16

    Sensitivity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  2. Sensitivity of candidate biomarker NELL1

    Sensitivity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  3. Sensitivity of candidate biomarker AKAP12

    Sensitivity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  4. Sensitivity of candidate biomarker TAC1

    Sensitivity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  5. Sensitivity of candidate biomarker HPP1

    Sensitivity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  6. Specificity of candidate biomarker p16

    Specificity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  7. Specificity of candidate biomarker NELL1

    Specificity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  8. Specificity of candidate biomarker AKAP12

    Specificity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

    Measured: 1 day

  9. Specificity of candidate biomarker TAC1

    Specificity of each candidate biomarker will be calculated by measuring the area under receiver operating characteristic curve generated from methylation index data.

Questions about this trial

What is this clinical trial studying?

An observational study of Barrett Esophagus and Esophageal Cancer, run by Johns Hopkins University at 2 sites 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 3 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 16 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Stephen J Meltzer, M.D. (4105026071, smeltzer@jhmi.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference in methylation of gene markers to discriminate Barrett's esophagus from non-pathological esophageal squamous and gastric cardia tissue. (time frame: 1 day). The study lists 3 primary outcomes in all. 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 16 Dec 2025.
