About this study

Official title: A Randomized, Placebo-Controlled Phase II Clinical Trial of Omega-3 PUFA Dietary Supplementation in Patients With Stage I-III Breast Carcinoma

This phase II clinical trial studies how well omega-3 fatty acid works in treating patients with stage I-III breast cancer. Studying samples of tissue and blood in the laboratory from breast cancer patients receiving omega-3 fatty acid may help doctors learn more about the effects of omega-3 fatty acid on tumor cells.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine if omega-3 dietary supplementation (omega-3 fatty acid) results in higher polyunsaturated fatty acids (PUFA) levels in surgical specimens of normal and malignant breast tissue in women who took omega 3 tablets in comparison to those who took placebo.

II. To determine if omega-3 dietary supplementation results in higher PUFA levels in plasma and red blood cells in women who took omega 3 tablets in comparison to those who took placebo.

III. To determine if omega-3 dietary supplementation affects the metabolites of omega-3 and omega-6 PUFA in surgical specimens of malignant and normal breast tissue in comparison to controls.

IV. To determine if women who take omega-3 dietary supplementation have less proliferation and greater apoptosis in malignant breast tissue in comparison to women who take placebo.

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

ARM I: Patients receive omega-3 fatty acid orally (PO) daily for 7-14 days.

ARM II: Patients receive placebo PO daily for 7-14 days.

What is being measured

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

  1. PUFA Levels in Normal and Metastatic Breast Tissue

    Analysis of variance (ANOVA) will be used to assess the effect of omega-3 dietary supplementation on PUFA levels separately in normal and malignant breast tissue. Analysis of covariance (ANCOVA) will be used to assess the omega-3 effect in plasma and red blood cells (RBC), where the baseline levels of the PUFAs will be included as covariates. PUFA Levels analyzed were 18:2 n-6, 18:3 n-3, 20:2 n-6, 20:4 n-6, 20:3 n-3, 20:5 n-3, 22:6 n-3

    Measured: At time of surgery

  2. PUFA Levels in Plasma Pre and Post Surgery

    Analysis of variance (ANOVA) will be used to assess the effect of omega-3 dietary supplementation on PUFA levels separately in normal and malignant breast tissue. Analysis of covariance (ANCOVA) will be used to assess the omega-3 effect in plasma and red blood cells (RBC), where the baseline levels of the PUFAs will be included as covariates. PUFA Levels analyzed were 18:2 n-6, 18:3 n-3, 20:2 n-6, 20:4 n-6, 20:3 n-3, 20:5 n-3, 22:6 n-3

    Measured: Pre and post surgery

  3. PUFA Levels in Red Blood Cells Pre and Post Surgery

    Analysis of variance (ANOVA) will be used to assess the effect of omega-3 dietary supplementation on PUFA levels separately in normal and malignant breast tissue. Analysis of covariance (ANCOVA) will be used to assess the omega-3 effect in plasma and red blood cells (RBC), where the baseline levels of the PUFAs will be included as covariates. PUFA Levels analyzed were 18:2 n-6, 18:3 n-3, 20:2 n-6, 20:4 n-6, 20:3 n-3, 20:5 n-3, 22:6 n-3

    Measured: Pre and post surgery

Secondary outcomes (3)
  1. Metabolites of Omega-3 and Omega-6 PUFA in Malignant and Normal Breast Tissue

    ANOVA will be used to assess the effect in normal and malignant breast tissue. Metabolites tested: PGE2, PGD2, 20-HETE, 5-HEPE, 13-HODE, 9-HODE, 15-HETE, 12-HETE, 5-HETE.

    Measured: At time of surgery

  2. Number of Days to Establish Difference in Proliferation in Malignant Breast Tissue

    ANOVA will be used to assess the effect of the supplementation in malignant breast tissue with less proliferation in malignant breast tissue in comparison to women who took the placebo.

    Measured: At time of surgery

  3. Number of Days to Establish Increased Apoptosis in Malignant Breast Tissue

    ANOVA will be used to assess the effect of the supplementation in malignant breast tissue with greater apoptosis in malignant breast tissue in comparison to women who took the placebo.

    Measured: At time of surgery

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing omega-3 fatty acid and laboratory biomarker analysis in people with Ductal Breast Carcinoma in Situ and Lobular Breast Carcinoma in Situ, run by Wake Forest University Health Sciences 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 6 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 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. 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 30 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?

PUFA Levels in Normal and Metastatic Breast Tissue (time frame: At time of surgery). The study lists 3 primary outcomes in all. 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 Oct 2019.
