About this study

Treat Barrett's esophagus (BE) patients with tamoxifen to Barrett's metaplasia as measured by changes in Barrett's esophagus appearance by endoscopy and histology as well as changes in SOX2 and CDX2.

Read the detailed description

Treat Barrett's esophagus (BE) patients with tamoxifen to determine the effects on Barrett's metaplasia as measured by changes in Barrett's esophagus appearance by endoscopy and histology. Tamoxifen treatment may induce SOX2 expression, decrease CDX2 and promote esophageal stem cell activity, leading to regression of Barrett's metaplasia. To test this hypothesis, we will conduct a prospective, pilot study where patients with BE, without high grade dysplasia, are treated with tamoxifen and assessed for changes in the appearance of their BE by endoscopy and histology as well as changes in the SOX2/CDX2 ratio indicative of an improvement in BE metaplasia

What is being measured

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

  1. Extent of Barrett's involvement and changes in histology

    The biopsy procedures with 4 quadrant biopsies/2 cm for histology and additional biopsies for freezing for macromolecular analysis to assess the preliminary diagnostic value of this marker pair in identifying levels of metaplasia in BE and as an indicator of response to tamoxifen treatment. The tissue from the two endoscopic procedures will be assessed for changes in the following related to tamoxifen therapy.

    Measured: End of 12 weeks (at the time of second endoscopy)

Secondary outcomes (3)
  1. Changes in SOX2 and CDX2 expression

    The main outcome measurements are SOX2 and CDX2, analyzed as a ratio. We will use a one sample paired non-parametric Wilcoxon test to test the significant difference if the ratio difference is not normally distributed. Normality assumption can be examined by visual Q-Q plot and formal Kolmogorov-Smirnov statistic. In addition, we will explore the patient level characteristics on treatment effect using a linear regression model. Specifically, we will use the difference ratio as the response variable and patient characteristics of interest as explanatory variables. Regression coefficients associated with the explanatory variables quantify the effect of these variables on the difference ratio, with t or F statistic testing for the statistical significance.

    Measured: End of 12 weeks (at the time of second endoscopy)

  2. Tolerance of tamoxifen

    As measured by toxicities using CTCAE version 4.0

    Measured: 4 months (30 days after cessation of tamoxifen or after second endoscopy - whichever occurs later)

  3. Changes in the length of Barrett's esophagus involvement

    Measured: End of 12 weeks (at the time of second endoscopy)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Tamoxifen and Endoscopy in people with Barrett Metaplasia, run by Washington University School of Medicine at 1 site in United States.

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 10 inclusion and 9 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: stopped early, as of the sponsor's last update on 13 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

The study was stopped early (reason given: Insufficient funding). Results are not available in the source record.

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?

Extent of Barrett's involvement and changes in histology (time frame: End of 12 weeks (at the time of second endoscopy)). 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 NCT02089386, which also lists 2 linked publications.

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 13 Mar 2017.
