NCT00637988

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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

    Baseline esophageal biopsies will be taken and thereafter at Day 10 in each treatment period.

Secondary Outcomes (1)

  • 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.

    Baseline esophageal biopsies will be taken and thereafter at Day 10 in each treatment period
