At the MGH 100 participants with a previous diagnosis of Barrett's Esophagus (BE) will be enrolled.\n\nEach subject will undergo a minimum of 2 esophagogastroduodenoscopies (EGD), one around the time of inclusion into the study and one at the end of the study, and 4 TCE imaging sessions (baseline, 1-year, 2-years and at the end of the 3-years follow-up). If it is determined by the treating physician that additional EGDs are needed, for extended follow-up or treatment, capsule imaging will be performed whenever possible.\n\nParticipants will have received written information prior to the day of the capsule procedure and participants will have another chance to discuss the procedure with the study coordinator and clinical study staff during the consent process prior to the capsule procedure. Participation in this study is completely voluntary, and the participant can stop the procedure at any time.\n\nFor each of the imaged participants, inclusion criteria and clinical characteristics such as age, sex, body mass index (BMI), current medication regimen, smoking history and GI related history will be recorded in the clinical form.\n\nParticipants will be seated and asked to sip water to facilitate swallowing the capsule.\n\nThe device will be operated by experienced study staff trained in the procedure such as a registered nurse or one of the endoscopist co-investigators in this study. Emergency phone and/or pager contact of the collaborating GI clinician(s) will be provided. They will also be accessible during the procedure if any problems are encountered that require their expertise.\n\nImaging will be performed in the same manner as in our other current IRB approved tethered capsule endomicroscopy studies. The capsule position will be controlled manually via the tether outside of the participant's mouth by the catheter operator. Recorded real-time cross-sectional images displayed on the monitor and distance marks on the tether will be used for confirmation of capsule position in the esophagus. Images will be viewed in real time to determine when the capsule has reached the stomach. The resistance of the tether can also give information of the cardia position. Once in the stomach, the capsule will be gradually pulled back up through the esophagus to the mouth, also while imaging. The capsule may be repositioned for imaging up to 4 times up and 4 times down the esophagus. The participant may be asked to swallow a different size capsule (ranging from 5-12.8 mm in diameter and 20-30 cm in length) to obtain the best distal esophageal images. It is expected that the maximum experimental time including swallowing the capsule, the imaging procedure, and removal of the capsule will take approximately 10 minutes in total."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Participants with known BE without high grade dysplasia, intramucosal adenocarcinoma or esophageal adenocarcinoma, confirmed by endoscopic biopsy.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Participants with known BE without high grade dysplasia, intramucosal adenocarcinoma or esophageal adenocarcinoma, confirmed by endoscopic biopsy,\n* Participants over the age of 18\n* Participants who are capable of giving informed consent\n* Participants who had or will have a standard of care EGD within 9 to 15 months\n* Participants must have no solid food for at least 4 hours prior to the procedure, and only clear liquids for 2 hours prior to the procedure.\n\nExclusion Criteria:\n\n* Participants with prior endoscopic ablation or resection treatment of BE\n* Participants with esophageal fistula and/or esophageal strictures with a luminal stricture diameter that is smaller than the diameter of the capsule\n* Participants with the inability to swallow capsules.\n* Pregnancy, according to participant information'}, 'identificationModule': {'nctId': 'NCT02994693', 'briefTitle': "Natural History of Barrett's Esophagus Using Tethered Capsule Endomicroscopy", 'organization': {'class': 'OTHER', 'fullName': 'Massachusetts General Hospital'}, 'officialTitle': "Natural History of Barrett's Esophagus Using Tethered Capsule Endomicroscopy", 'orgStudyIdInfo': {'id': '2016-P000919'}, 'secondaryIdInfos': [{'id': '5R01CA184102-02', 'link': 'https://reporter.nih.gov/quickSearch/5R01CA184102-02', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'label': 'OFDI capsule imaging', 'description': 'Participants will swallow the OFDI capsule and imaging will be acquired using the OFDI imaging system.', 'interventionNames': ['Device: OFDI capsule imaging']}], 'interventions': [{'name': 'OFDI capsule imaging', 'type': 'DEVICE', 'description': "Imaging of Barrett's esophagus (BE) using OFDI capsule imaging", 'armGroupLabels': ['OFDI capsule imaging']}]}, 'contactsLocationsModule': {'locations': [{'zip': '02114', 'city': 'Boston', 'state': 'Massachusetts', 'country': 'United States', 'facility': 'Massachusetts General Hospital', 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}], 'overallOfficials': [{'name': 'Guillermo Tearney, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Massachusetts General Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Massachusetts General Hospital', 'class': 'OTHER'}, 'collaborators': [{'name': 'National Institutes of Health (NIH)', 'class': 'NIH'}, {'name': 'National Cancer Institute (NCI)', 'class': 'NIH'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator - MD, PhD, FACC, FCAP, FNAI', 'investigatorFullName': 'Guillermo Tearney', 'investigatorAffiliation': 'Massachusetts General Hospital'}}}}
