Measure PGE production in Barrett's metastatic tissue & determine the reduction from baseline of PGE production would be equivalent on Day 10 in esomeprazole 40mg bid + aspirin treatment compared to esomeprazole 40 mg bid + rofecoxib 25 mg qd treatment [ Time Frame: Baseline esophageal biopsies will be taken and thereafter at Day 10 in each treatment period. ]

To determine in which of the four treatment groups the reduction in the baseline in PGE2 production, COX-2 enzyme activity and PCNA expression in Barrett's metaplastic tissue is the greatest. [ Time Frame: Baseline esophageal biopsies will be taken and thereafter at Day 10 in each treatment period ]

Barrett's Esophagus - 315 - 3 Way Cross Over
A Multicenter, Open-Label, Four-Way Crossover Study of the Effects of Esomeprazole, Aspirin and Rofecoxib on Prostaglandin (PGE2) Production, Cyclooxygenase-2 Enzyme Activity and PCNA Expression in Patients With Barrett's Esophagus

This study evaluates PGE2 production, COX-2 enzyme activity and PCNA expression in Barrett's metaplastic tissue. All patients will have a baseline endoscopy with multiple biopsies. The patients will then be receive four dosing regimens (esomeprazole, esomeprazole and aspirin, esomeprazole and rofecoxib, or rofecoxib alone) consecutively each for a 10 day dosing period, whilst undergoing further follow up endoscopies and multiple biopsies.
