Using orally administered zinc to patients already diagnosed with the pre-cancerous condition, Barrett's Esophagus, this study is asking two questions:

  1. can this zinc administration cause molecular-level changes in the Barrett's tissue?
  2. are the changes measured indicative of chemopreventive action by zinc regarding cancer progression?

Condition Intervention Phase
Barrett's Metaplasia Drug: zinc gluconate Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Primary Purpose: Prevention
Official Title: Effect of Zinc on Barrett's Metaplasia

Primary Outcome Measures:
  • Changes in zinc-regulated cellular proteins within Barrett's tissue [ Time Frame: in biopsy tissue after 14 days of Zn exposure ]

Secondary Outcome Measures:
  • Changes in cellular microRNA profile; changes in protein cancer biomarkers [ Time Frame: in biopsy tissue after 14 days of Zn exposure ]

Estimated Enrollment: 120
Study Start Date: April 2011
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Zinc Drug: zinc gluconate
26.6 mg zinc BID (as zinc gluconate)
Placebo Comparator: sodium

Detailed Description:
14 days prior to already-scheduled upper endoscopy (EGD) procedures for routine surveillance of Barrett's tissue, patients who have given written, informed consent are randomized (sealed envelope method) and placed on an oral dose of zinc gluconate (26.6 mg zinc BID) or a placebo (molar equivalent of sodium gluconate BID) for 14 days. At the time of endoscopy, 4 biopsies are taken (and pooled) from the Barrett's tissue and 4 from proximal normal esophageal tissue. Biopsies are flash frozen for later analyses by atomic absorption spectroscopy, PAGE and Western immunoblot or RNA microarray.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:ages 18-80; prior diagnosis of Barrett's esophagus -

Exclusion Criteria:unable to provide written, informed consent; prior history of Barrett's dysplasia or esophageal adenocarcinoma; drug exclusions: hormone replacement therapy, cholestyramine, amiloride diuretics, oral quinolone antibiotics, glucocorticoids, corticosteroids, anticoagulants (other than aspirin)
