NCT06803927

Brief Summary

This study is looking at cells collected from the esophagus using a diagnostic device called the EndoSign® Cell Collection Device (a sponge on a thread). Subjects swallow a capsule, which dissolves in the stomach and releases a sponge that collects cells from the esophagus as the sponge is withdrawn using the thread. These cells will be tested to check for a condition called "Barrett's Esophagus." The cells from the sponge will be tested using Cyted Health biomarkers and compared to the results from a regular endoscopy and any biopsies that are taken. To do this, we need sponge samples from people who might have Barrett's Esophagus based on their risk factors, and from people with Barrett's Esophagus. Subjects will have one visit to have the Endosign Cell Collection Device administered prior to having a standard of care endoscopy. They will answer some questions about their medical history and experience with the cell collection procedure as part of the study. Data will be collected from medical records including post-endoscopy.

Outcome Measures

Primary Outcomes (1)

  • Performance of Barrett's Esophagus Test (LDT) compared to standard of care.

    Performance of the biomarker for detecting BE or confirming no BE in the study population including sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) on samples collected using the EndoSign Cell collection device as compared to endoscopy and pathology.

    Sample collection prior to standard of care endoscopy

Secondary Outcomes (1)

  • Assess subject experience with the EndoSign Cell Collection Device

    Through the end of the study-about 9 months

Other Outcomes (1)

  • Interim assessment of number of subjects with each diagnosis

    Halfway through the study at about 4 months

Study Arms (2)

High Risk Screening without Barrett's Esophagus-closed 11/2025

Subjects with chronic GERD plus 3 other defined risk factors for Barrett's Esophagus (ACG) (e.g., age \>50, male, white, obese, family history) who have had a standard of care endoscopy in which no Barrett's esophagus was identified.

Device: Barrett's Esophagus Test (LDT)

Barrett's Esophagus

Subjects with known Barrett's esophagus with or without dysplasia/cancer identified or confirmed (surveillance) via a standard of care endoscopy

Device: Barrett's Esophagus Test (LDT)

Interventions

Barrett's Esophagus Test (LDT) will be performed on esophageal cells collected using the EndoSign Cell Collection Device (510(k) cleared) and compared to the results of standard of care EGD plus biopsies (if applicable)

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Subjects scheduled for EGD (upper endoscopy) that meet the eligibility criteria at recruiting centers.

You may qualify if:

  • Undergoing a standard of care EGD (with or without endoscopic eradication therapy {EET})
  • Willing to undergo non-endoscopic sampling with the study device prior to EGD (up to 6 weeks prior to EGD/EET or day of EGD/EET).
  • Willing and able to sign informed consent
  • Confirmed Barrett's Esophagus of length at least 1 cm or greater. This includes non-dysplastic Barrett's, low-grade dysplasia, high-grade dysplasia or adenocarcinoma.

You may not qualify if:

  • Previous EGD result was indefinite for dysplasia
  • Previous endoscopic eradication therapy (EET)
  • Current dysphagia (unable to swallow a pill the size of the capsule (8.5 mm dia.))
  • Known or suspected gastric or esophageal varices
  • Known or suspected portal hypertension
  • Taking anti-thrombotic medications that cannot be discontinued
  • Taking GLP-1 agonists that cannot be discontinued for 1 week prior to sponge administration
  • Previous gastric or esophageal surgery (including Nissen fundoplication)
  • History of oropharyngeal tumor
  • History of myocardial infarction or cerebrovascular accident in past 6 months
  • Known or suspected to be pregnant (self-report for woman of child-bearing potential)
