Where you'd take part

This study runs at 3 sites. They're the same protocol — you choose where, and that choice sets who your contact draft is addressed to.

  • Mayo Clinic in Arizona

    Scottsdale, Arizonano site contact published

  • Mayo Clinic in Florida

    Jacksonville, Floridano site contact published

  • Mayo Clinic in Rochester

    Rochester, Minnesotano site contact published

Sites open and close at different times, so the status above is per site — it can differ from the study's overall status.

Eligibility criteria

Inclusion

Patient between the ages 18 - 90
Patients with a BE segment \>= 1cm in maximal extent endoscopically
Histology showing evidence of intestinal metaplasia with or without presence of dysplasia
Undergoing clinically indicated endoscopy

Exclusion

Patients with a prior history of ablation (photodynamic therapy, radiofrequency ablation, cryotherapy, argon plasma coagulation). Patients with a history of endoscopic mucosal resection alone will not be excluded
Patients with a history of esophageal or gastric resection for esophageal or gastric carcinoma
Subjects with known evidence of BE (on history or review of medical records)
Pregnant or lactating females
Patients who are unable to consent
Patients with a current history of uninvestigated dysphagia (this does not apply to the brushings/biopsies only portion of the study for RST/ARZ sites only)
History of eosinophilic esophagitis or achalasia
Patients on oral anticoagulation including Coumadin, and warfarin, unless discontinued for thee to five days prior to the sponge procedure. (This does not apply to the brushing/biopsy only portion of the study for RST/ARZ sites only)
Patients on antiplatelet agents including clopidogrel, unless discontinued for three to five days prior to the sponge procedure. (This does not apply to the brushing/biopsy only portion of the study for RST/ARZ sites only)
Patients on oral thrombin inhibitors including dabigatran and oral factor X an inhibitor such as rivaroxaban, apixaban, and edoxaban, unless discontinued for three to five days prior to the sponge procedure. (This does not apply to the brushing/biopsy only portion of the study for RST/ARZ sites only)
Patients with a history of known esophageal or gastric varices or cirrhosis
Patients with a history of esophageal or gastric resection
Patients with congenital or acquired bleeding diatheses
Patients with a history of esophageal squamous dysplasia
Patient has known carcinoma of the foregut (pancreatic, bile duct, ampullary, stomach, or duodenum) within 5 years prior to study enrollment
Patient has received chemotherapy class drugs or radiation to treat mediastinal or esophageal cancer
Patients with Familial Adenomatous Polyposis (FAP) or Lynch Syndrome

What this trial measures

  • Sensitivity of deoxyribonucleic acid (DNA) markersBaseline

    Will evaluate the sensitivity of DNA makers (methylated DNA markers ± aneuploidy) to distinguish between high-grade dysplasia (HGD)/esophageal adenocarcinoma (EAC) and non-dysplastic Barrett's esophagus (BE).

  • Specificity of DNA markersBaseline

    Will evaluate the specificity of DNA markers (methylated DNA markers ± aneuploidy) to distinguish between HGD/EAC and non-dysplastic BE.
