NCT01447927

Brief Summary

This randomized phase II trial studies how well metformin hydrochloride works in preventing esophageal cancer in patients with Barrett esophagus. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may keep esophageal cancer from forming.

Outcome Measures

Primary Outcomes (1)

  • Percent Change in Median pS6K1 Immunostaining Among Participants With Barrett Esophagus

    The percent change in pS6K1 was calculated as month 3 pS6k1 values minus baseline pS6k1 values, then divide by baseline pS6k1 values and multiply by 100.

    Baseline to 3 months

Secondary Outcomes (1)

  • Overall Adverse Event Rates

    Up to 30 days

Study Arms (2)

Arm I

EXPERIMENTAL

Patients receive extended-release metformin hydrochloride PO QD on week 1, and BID on weeks 2-12 (QAM QPM on week 3) in the absence of unacceptable toxicity or disease progression.

Drug: metformin hydrochloride

Arm II

PLACEBO COMPARATOR

Patients receive extended-release placebo PO QD on week 1and BID on weeks 2-12 (QAM and QPM on week 3) in the absence of unacceptable toxicity or disease progression.

Other: placebo

Interventions

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed diagnosis of Barrett esophagus, with no dysplasia, indeterminate for dysplasia, or low-grade dysplasia as defined by the presence of specialized columnar epithelium on histology and \>= 2 cm of involvement on endoscopy
  • Adequate Barrett mucosa, which is defined as \>= 1 out of 4 research samples (i.e., \>= 25%) with \>= 50% intestinal metaplasia in biopsies required to satisfy the endpoints of the study
  • No history of esophageal carcinoma or other cancer(s) (except for non-melanoma skin cancers)
  • No erosive esophagitis or ulcerative esophagitis, unless treatment with a proton pump inhibitor (PPI) results in healed erosions or ulcers prior to entry endoscopy
  • No history of high-grade dysplasia or cancer (confirmed locally by esophagogastroduodenoscopy \[EGD\] and Pathology reports)
  • No ulcer, plaque, nodule, stricture, or other luminal irregularity within the Barrett segment, unless clinical biopsy produces no evidence of high-grade dysplasia or cancer
  • ECOG performance status =\< 1
  • Hemoglobin \>= 10 g/dL
  • Leukocytes \>= 3,000/mL (\>= 2,500/mL for African-American participants)
  • Absolute neutrophil count \>= 1,500/mL (\>= 1,000/mL for African-American participants)
  • Platelets \>= 100,000/mL
  • Total bilirubin =\< institutional upper limit of normal (ULN)
  • AST (SGOT) and ALT (SGPT) =\< 1.5 times institutional ULN
  • Creatinine =\< institutional ULN
  • Willingness to provide tissue samples for research purposes
