Spit test could spot esophagus condition before it turns cancerous
NCT ID NCT05133102
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether taking multiple saliva samples over time can better detect Barrett's esophagus, a condition where the lining of the food pipe changes and can raise the risk of cancer. About 275 adults who have had or will have an endoscopy will provide saliva samples. Researchers will analyze the bacteria in the mouth to see if a simple, non-invasive test can help diagnose this condition earlier.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Enrollment will continue until a total of 250 subjects complete all three saliva specimen collections: * 50 BE patients * 200 controls The investigators anticipate that approximately 10% of subjects will not complete all three specimen collections and will be excluded from the primary outcome analyses. Thus, the investigators expect to enroll \~275 subjects to have 250 with three saliva specimen collections. There is no cap on enrollment per study site. The anticipated duration of enrollment is 2 years (24 months).
