Official title
A Multicenter Case-Control Study of the Efficacy of EsoGuard on Samples Collected Using EsoCheck, Versus Esophagogastroduodenoscopy, for the Diagnosis of Barrett's Esophagus With and Without Dysplasia, and for Esophageal Adenocarcinoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study will assess the performance of the combined system, i.e., the use of the EsoGuard assay (lab developed test) on cells collected using the EsoCheck (501k cleared device) to detect Barrett's Esophagus (BE), with or without dysplasia, and esophageal adenocarcinoma (EAC) as compared to Esophagogastroduodenoscopy (EGD) plus biopsies in both confirmed cases of BE/EAC and in controls (subjects without a prior diagnosis but undergoing screening for BE/EAC)
