About this study

Official title: Phase II Clinical Trial to Determine if Polyphenon E Inhibits c-Met Signaling and Activation of Pathways Contributing to Breast Cancer Progression

To see if an extract of green tea can affect certain markers of breast cancer and breast cancer progression in women with a recent biopsy positive for cancer and who are scheduled for surgery.

Read the detailed description

To evaluate the short-term effects of a daily dose of Polyphenon E administered during the interval between breast biopsy and surgery in women with recently diagnosed breast cancer. Endpoints will be changes in serum and tissue biomarkers related to progression of cancer.

The effect of Polyphenon E on tumor cell c-Met expression and phosphorylation is the primary objective. Secondary objectives include the effects on the other tissue and serum biomarkers. Evaluation of the safety and tolerability of Polyphenon E in this subject population is another objective.

1.1 Determine the effects of Polyphenon E on tumor cell c-Met expression and phosphorylation levels in patients with breast cancer

1.2 Determine the effects of Polyphenon E on PI-3K activation in patients with breast cancer

1.3 Determine the effects of Polyphenon E on MAPK activation in patients with breast cancer

1.4 Determine the effects of Polyphenon E on expression levels of other proteins involved in motility and invasion such as Rho GTPases and extracellular proteinases in patients with breast cancer

1.5 Determine the effects of Polyphenon E on markers of angiogenesis in patients with breast cancer

1.6 Determine the effects of Polyphenon E on other serum markers: C-reactive protein (CRP), Insulin-Like Growth factor I (IGF-I), Insulin-like Growth Factor Binding Protein 3 (IGFBP-3) and Hepatocyte Growth Factor HGF

1.7 Evaluate the safety and tolerability of Polyphenon E in this subject population

What is being measured

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

  1. Change in Serum VEGF in Breast Cancer

    Change in serum VEGF from baseline to post treatment with polyphenon E.

    Measured: Baseline and 4 to 6 weeks

  2. Change in Serum HGF and Breast Cancer

    Change in serum HGF from baseline to post Polyphenol E treatment.

    Measured: Baseline and 4 to 6 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Polyphenon E in people with Breast Cancer, run by Louisiana State University Health Sciences Center Shreveport at 2 sites 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 7 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: finished, as of the sponsor's last update on 21 Sep 2017. 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 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 26 Oct 2012). 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?

Change in Serum VEGF in Breast Cancer (time frame: Baseline and 4 to 6 weeks). The study lists 2 primary outcomes in all. 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 NCT00676793, 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 21 Sep 2017.
