About this study

Official title: A Double Blind Prospective Study of Metformin vs. Placebo in Overweight or Obese Post-menopausal Women at Elevated Risk for Breast Cancer

This randomized clinical trial studies metformin hydrochloride in overweight or obese patients at elevated risk for breast cancer. Metformin hydrochloride may decrease the expression of early tumor makers in breast tissue of patients at increased risk for breast cancer

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the changes in the signal pathway profiling of breast tissue using reverse phase proteomics in tissue biopsy of overweight or obese women at elevated risk for breast cancer treated with metformin (metformin hydrochloride) (850mg orally twice a day) for 12 cycles.

SECONDARY OBJECTIVES:

  1. To determine the effect of metformin on breast tissue density of overweight or obese women at elevated risk for breast cancer using qualitative mammographic fat density criteria.

II. To determine the effect of metformin on the insulin axis in serum of overweight or obese women at elevated risk for breast cancer treated with metformin (850mg orally twice a day) for 12 cycles.

III. To determine the toxicities associated with metformin.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive metformin hydrochloride by mouth once daily on days 1-30 in course 1 and twice daily on days 1-30 thereafter. Treatment repeats every 30 days for 12 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive placebo by mouth once daily on days 1-30 in course 1 and twice daily on days 1-30 thereafter. Treatment repeats every 30 days for 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 5 years.

What is being measured

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

  1. Changes in the phosphorylation of proteins after metformin exposure

    Reverse phase proteomic assays (RPPA) will be performed to measure changes in the phosphorylation of proteins after metformin exposure. Changes in the phosphorylation of proteins after metformin exposure will be calculated and compared using two-sample t-tests. As a supplemental analysis, analysis of covariance (ANCOVA) will be used to model the 12 month levels adjusted for baseline. Assumptions for analysis will be checked and non-parametric methods used if needed; however it is expected that the data will be normally distributed on the log scale.

    Measured: Baseline and 12 months

Secondary outcomes (2)
  1. Changes in ordinal level of breast density

    Changes in ordinal level of breast density will be performed using the breast density criteria previously established by Boyd and colleagues (New England Journal of Medicine 2007). Each image will be grouped into one of six categories: 0%, <10%, 10-25%, 25-50%, 50-75% and >75%. Changes will be compared between the two groups using Wilcoxon Rank-Sum tests.

    Measured: Baseline and 12 months

  2. Proportion of patients experiencing adverse events assessed using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    Will be tabulated by arm and grade.

    Measured: Up to 30 days

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing metformin hydrochloride and laboratory biomarker analysis in people with Breast Cancer and Obesity, run by Anna Maria Storniolo 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 25 inclusion and 7 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 30 Mar 2018. 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. 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?

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes in the phosphorylation of proteins after metformin exposure (time frame: Baseline and 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Mar 2018.
