Outcome Measures

Primary Outcomes (2)

  • Change in Serum PGE2 Levels

    Percent change from baseline to 6 months in serum prostaglandin E2 (PGE2) level obtained from blood draw

    Baseline, 6 months

  • Change in Esophageal Tissue PGE2 Levels

    Percent change from baseline to 6 months in esophageal tissue prostaglandin E2 (PGE2) level obtained from endoscopic esophageal tissue collection

    Baseline, 6 months

Secondary Outcomes (1)

  • Change in Esophageal Macrophage Markers

    Baseline, 6 months

Study Arms (2)

Placebo

PLACEBO COMPARATOR

Subjects with known Barrett's Esophagus (no dysplasia and low-grade dysplasia) will receive a placebo which looks exactly like the study drug, but contains no active ingredient, to be taken orally for six months.

Drug: Placebo

Omega-3 polyunsaturated fatty acids

ACTIVE COMPARATOR

Subjects with known Barrett's Esophagus (no dysplasia and low-grade dysplasia) will receive Omega-3 free fatty acids supplements to be taken orally for six months.

Drug: Omega-3 polyunsaturated fatty acids

Interventions

3 capsules a day of Omega 3 polyunsaturated fatty acids taken orally for six months; 2 capsules with breakfast and 1 capsule with their evening meal. Active drug will consist of 1200 mg of a ω3 FFA preparation containing 675 mg EPA and 300 mg DHA.

Also known as: Docosahexaenoic Acid (DHA)/Eicosapentaenoic Acid (EPA)
Omega-3 polyunsaturated fatty acids

3 capsules a day of placebo (1200 mg of ethyl oleate 3 capsules a day) taken orally for six months; 2 capsules with breakfast and 1 capsule with their evening meal.
