The study will compare the effectiveness of endoscopic surveillance and endoscopic eradication therapy (EET) for the management of Barrett's esophagus (BE) and low-grade dysplasia (LGD).

This NIH sponsored research study with an industry collaborator (MAGNUS) is being conducted at up to five study centers throughout the United States. MUSC is the lead site. Up to 100 inpatient participants with a diagnosis of MDD will be enrolled in this double-blind, randomized, study. There are 2 study arms: active SAINT® and sham "fake" SAINT®. Patients will be randomly assigned, like the flip of a coin (50:50 chance), to active or sham SAINT®.
