Esomeprazole Magnesium With or Without Aspirin in Preventing Esophageal Cancer in Patients With Barrett Esophagus

This study has been completed.

This randomized phase II trial is studying the effect of esomeprazole magnesium and aspirin on tissue PGE2 levels compared with esomeprazole and placebo. This type of chemoprevention treatment investigates the use of certain drugs to assess whether they assist in the prevention of cancer. The use of esomeprazole magnesium with or without aspirin may help prevent esophageal cancer in patients with Barrett esophagus.

Condition Intervention Phase
Barrett Esophagus
Esophageal Cancer
Drug: acetylsalicylic acid
Drug: esomeprazole magnesium
Other: placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Change in Mean Tissue Prostaglandin E2 (PGE2) Concentration as Determined From Barrett's Research Mucosal Biopsy Samples [ Time Frame: Baseline to 30 days after completion of study treatment ]
    The mean tissue PGE2 is reported for each Arm.

Secondary Outcome Measures:
  • Toxicity [ Time Frame: Up to 30 days after completion of study treatment ]
    Toxicity is defined as adverse events that are classified as either possibly, probably, or definitely related to the interventional agent, graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. The number of patients reporting adverse events will be tabulated by grade.
