About this study

Official title: A Phase II Pilot Study Using Metformin to Reduce Cardiac Toxicity in Breast Cancer Patients

The goal of this study is to determine if co-administration of metformin and doxorubicin in breast cancer patients receiving neoadjuvant or adjuvant therapy will reduce the number of patients who develop a significant change in left ventricle ejection fraction (LVEF).

Read the detailed description

This is a randomized, open-label, phase II design pilot study in patients with breast cancer requiring neoadjuvant or adjuvant chemotherapy. Eligible patients will be equally randomized to either receive metformin plus standard of care therapy or standard of care therapy alone. Patients receiving metformin will continue drug until the doxorubicin-containing cycles are complete, unless unacceptable toxicity occurs or the patient decides to withdraw from the study. Both arms of the study will undergo echocardiograms with contrast at baseline, upon completion of doxorubicin-containing cycles (within 28 days of completion), and at the one-year and seven-year time points. Additionally biomarker labs will be obtained to explore if there is a correlation between change in cardiac activity and the activity of metformin. If willing, all enrolled patients will provide a sample of whole blood for further exploratory analysis. Symptoms reported during the study will be correlated with know single nucleotide polymorphisms (SNPs) found during an exploratory genomic analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MetforminDrug

    Also called Glucophage

    Metformin will begin to be administered prior to treatment with doxorubicin. Metformin will continue to be given throughout doxorubicin cycles until the completion of doxorubicin therapy.

  • DoxorubicinDrug

    Standard of care treatment with doxorubicin

Study groups in NCT02472353
Study groupRoleWhat they receive
Standard of CareActive comparatorPatients will receive standard of care for their breast cancer with no metformin during their treatment with doxorubicin.
Receives: Drug: Doxorubicin
Metformin + Standard of CareExperimentalPatients will receive metformin during their treatment with doxorubicin for their breast cancer.
Receives: Drug: Metformin; Drug: Doxorubicin

What is being measured

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

  1. Number of Participants With Less Than or Equal to 5% Decrease in Left Ventricle Ejection Fraction (LVEF) on Echocardiogram

    Determine whether the addition of metformin to standard doxorubicin therapy in breast cancer patients will decrease the incidence of change in left ventricle ejection fraction (LVEF).

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Metformin and Doxorubicin in people with Breast Cancer and Breast Tumors, run by Avera McKennan Hospital & University Health Center 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 4 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 16 Oct 2019. 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?

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 16 Oct 2019). 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?

Number of Participants With Less Than or Equal to 5% Decrease in Left Ventricle Ejection Fraction (LVEF) on Echocardiogram (time frame: 1 year). 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 NCT02472353, 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 16 Oct 2019.
