About this study

Official title: Targeted Chemoprevention of Gastric Carcinogenesis in High Risk Populations

A clinical study of the efficacy of oral alpha-difluoromethylornithine (eflornithine or DFMO) in male and female subjects ages 30-60 with gastric premalignant lesions in two high risk regions of Latin America.

Read the detailed description

Primary Objective

  • The difference in cell DNA damage between patients treated with DFMO and patients treated with placebo at 6 months. The cell DNA damage is measured using the percent positive gastric epithelial cells assessed by IHC for gamma H2AX. The mean difference between the two groups at 6 months will be calculated, accounting for their baseline measurements.

Secondary Objectives

  • The difference in cell DNA damage between patients treated with DFMO and patients treated with placebo for 18 months, and then followed for an additional 6 months. The cell DNA damage is measured using the percent positive gastric epithelial cells assessed by IHC for gamma H2AX. The mean difference between the two groups at 18 and 24 months will be calculated, accounting for their baseline measurements.
  • The differences in the gastritis histopathology score between patients treated with DFMO and patients treated with placebo for a total of 18 months, and followed for an additional 6 months. The gastritis histopathology score is measured with a quantitative scale 0.0-6.0, for atrophy, intestinal metaplasia, and dysplasia. The mean differences between the two groups at 6, 18, and 24 months will be calculated using mixed models, accounting for their baseline measurements.
  • Number of patients with quantitative toxicities. Toxicities will be assessed per CTCAE criteria, and each toxicity will be assigned an adverse event (AE) term according to CTCAE definitions (each AE term = unique representation of a specific event used for medical documentation and scientific analyses), and graded as defined by CTCAE (grade 1 = mild; grade 2 = moderate; grade 3 = severe or significant but not immediately life-threatening; grade 4 = life-threatening; grade 5 = death).
  • To evaluate whether candidate single nucleotide polymorphisms (SNPs) relevant to eflornithine (DFMO) efficacy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gastric Epithelial Cell DNA Damage, at 6 Months Versus Baseline

    The cell DNA damage is measured by the percent positive gastric epithelial cells, as assessed by IHC for gamma H2AX. The mean differences at 6 months versus baseline of the percent positive gastric epithelial cells is compared between the two groups.

    Measured: Baseline up to 6 months

Secondary outcomes (5)
  1. Gastric Epithelial Cell DNA Damage, at 18 Months Versus Baseline

    The cell DNA damage is measured using the percent positive gastric epithelial cells, as assessed by IHC for gamma H2AX. The mean differences in percent positive gastric epithelial cells at 18 months versus baseline is compared between the two groups.

    Measured: Baseline up to 18 months

  2. Gastric Epithelial Cell DNA Damage, at 24 Months Versus Baseline

    The cell DNA damage is measured by the percent positive gastric epithelial cells, as assessed by IHC for gamma H2AX. The mean differences at 24 months versus baseline of the percent positive gastric epithelial cells is compared between the two groups.

    Measured: Baseline up to 24 months

  3. Change in Gastric Histopathology Score, at 6 Months Versus Baseline

    The mean differences in the gastric histopathology score at 6 months versus baseline are calculated, with comparison of the eflornithine and placebo groups. The changes in histology stage are assessed with the validated Correa Histopathology Score system (ranges represent differences in severity and extent): normal mucosa 1, non-atrophic gastritis 2, multifocal atrophic gastritis without intestinal metaplasia 3.25-4.0, gastric intestinal metaplasia 4.3-5.0, dysplasia 5.25-5.75, and cancer 6. The Correa Histopathology Score is based upon the Updated Sydney System biopsy protocol (5 biopsies). The most advanced lesion (highest Correa score) in the stomach represents the summary Correa score for the patient at the given time point.

    Measured: Baseline up to 6 months

  4. Change in Gastric Histology Score, at 18 Months Versus Baseline

    The mean differences in the gastric histopathology score at 18 months versus baseline are calculated, with comparison of the eflornithine and placebo groups. The changes in histology stage are assessed with the validated Correa Histopathology Score system (ranges represent differences in severity and extent): normal mucosa 1, non-atrophic gastritis 2, multifocal atrophic gastritis without intestinal metaplasia 3.25-4.0, gastric intestinal metaplasia 4.3-5.0, dysplasia 5.25-5.75, and cancer 6. The Correa Histopathology Score is based upon the Updated Sydney System biopsy protocol (5 biopsies). The most advanced lesion (highest Correa score) in the stomach represents the summary Correa score for the patient at the given time point.

    Measured: Baseline up to 18 months

  5. Change in Gastric Histology Score, at 24 Months Versus Baseline

    The mean differences in the gastric histopathology score at 24 months versus baseline are calculated, with comparison of the eflornithine and placebo groups. The changes in histology stage are assessed with the validated Correa Histopathology Score system (ranges represent differences in severity and extent): normal mucosa 1, non-atrophic gastritis 2, multifocal atrophic gastritis without intestinal metaplasia 3.25-4.0, gastric intestinal metaplasia 4.3-5.0, dysplasia 5.25-5.75, and cancer 6. The Correa Histopathology Score is based upon the Updated Sydney System biopsy protocol (5 biopsies). The most advanced lesion (highest Correa score) in the stomach represents the summary Correa score for the patient at the given time point.

    Measured: Baseline up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Eflornithine in people with Gastric Cancer and Gastric Intestinal Metaplasia, run by Vanderbilt-Ingram Cancer Center at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Honduras, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Apr 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gastric Epithelial Cell DNA Damage, at 6 Months Versus Baseline (time frame: Baseline up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02794428, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2026.
