Collecting saliva to study Barrett’s esophagus over time
Part of Cancer, Digestive system clinical trials.
This study collects saliva (and, for some people, looks at stomach/esophagus samples) to understand how the mouth and gut “microbiome” changes over time in people with Barrett’s esophagus. It may help researchers find patterns that relate to Barrett’s esophagus and future risk.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have had an upper endoscopy in the past 3 years (or are scheduled for one)
- You can provide a saliva sample
- You can understand the study and sign informed consent
- If you have Barrett’s esophagus: your endoscopy must show Barrett’s (at least 1 cm) and biopsy tissue must show intestinal metaplasia

This trial tests a new, non-endoscopic screening method for Barrett's esophagus (a condition that can lead to cancer) in veterans who do not have chronic acid reflux. It aims to find early signs of the condition using a simple swallowable device, potentially avoiding the need for a traditional endoscopy.
This study tests less invasive ways to detect high-grade dysplasia (very abnormal cells) and esophageal cancer in people with Barrett's esophagus, a condition that can increase cancer risk. It looks for these changes using cell samples taken during a routine endoscopy, which may be quicker and more comfortable than standard biopsies.
This study compares two tissue-collection methods during an endoscopy for Barrett’s esophagus to see which one detects concerning changes better. Your results could help improve how doctors check Barrett’s over time.
This study compares two ways of taking tissue samples during endoscopy to check how Barrett’s esophagus is changing. The goal is to improve surveillance, especially for finding early precancer or early cancer changes.
This study aims to screen for Barrett's esophagus in people who are getting a routine colonoscopy but do not have chronic heartburn. It uses a simple, non-invasive cell collection device (EsoCheck) to see if you might have Barrett's esophagus, which can increase the risk of esophageal cancer.
This study follows people for 5 years to see how well a new biopsy-mapping test (WATS3D) works during routine upper endoscopy. It may help doctors find Barrett’s esophagus changes earlier and better guide follow-up after treatment.
