Study of Moderate Dose Omega 3 Fatty Acid Supplement in Premenopausal Women at High Risk for Breast Cancer

May 19, 2023 updated by: Lauren Nye

Feasibility Study of Moderate Dose Omega 3 Fatty Acid Supplementation in Premenopausal Women at High Risk for Breast Cancer Considering Future Pregnancy

This pilot study is an investigation of feasibility of moderate dose omega-3 fatty acid supplementation in pre-menopausal women at high risk for breast cancer who are considering future pregnancy. The goal of this pilot study is to determine feasibility of the study, document compliance with omega-3 fatty acid supplementation in this population and identify novel biomarkers modulated by moderate dose omega-3 fatty acids in this population.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Pregnancy and breast feeding are protective when they occur at an early age, typically at an age less than 30. The influence of pregnancy on breast cancer risk is not fully understood, and little is known about modulation of the breast microenvironment during pregnancy and its influence on risk. Hormones, including rising estrogen levels, play a role in fatty acid synthesis. In pre-clinical models, a rise in omega-3:omega-6 ratio occurs naturally in the breast of pregnant mice. This may be able to be accentuated in human breast tissue with omega-3 fatty acid supplementation. Omega-3 fatty acid supplementation has been shown to favorably modulate breast cancer risk and risk biomarkers in pre-menopausal women at high risk for breast. Omega-3 fatty acid supplementation during pregnancy has also been found to have positive outcomes for the offspring, making it an ideal intervention to study in this population.

This pilot study of omega-3 supplementation in pre-menopausal women at high risk for breast cancer who are still considering pregnancy is addressing a potential prevention strategy in a population otherwise excluded from breast cancer prevention trials and not eligible for standard of care chemoprevention. With this pilot, the intent is to establish feasibility, document tolerability, determine number of women needed to enroll based on pregnancy rate and identify biomarkers for future investigation. This information will provide necessary data to apply for future extramural funding for a larger randomized trial. In a larger randomized trial with longer follow up, we will be able to assess post-pregnancy breast tissue and biomarkers to examine efficacy of omega-3 fatty acid supplementation in breast cancer risk reduction.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 40 years (Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Women age 21 - 40 must be pre-menopausal as defined as having intact ovaries with regular menses or if not menstruating, have a premenopausal status confirmed by serum follicle-stimulating hormone (FSH) and estradiol.
  • Women must be considered at high risk for breast cancer based on family history (first or second degree relative diagnosed with breast cancer under the age of 60), prior precancerous biopsy or a 5-year Gail model risk estimate of ≥ 1.7% or 10 year Tyrer-Cuzick risk of 2x population risk as listed in the model.
  • Women must indicate that they are still considering future pregnancy and childbearing.
  • Women must be one year from pregnancy and breast-feeding.
  • Women must be willing to take supplemental omega-3 fatty acids provided by the study.

Exclusion Criteria:

  • Women actively undergoing in-vitro fertilization or fertility treatments are excluded.
  • Women currently pregnant or breast-feeding at time of study consent.
  • Women with an active malignancy.
  • Women on anticoagulation.
  • Women with bilateral breast implants or tram flap reconstruction.
  • Women who have had radiation to both breasts.
  • Women with current mammographic or clinical breast exam mass which is suspicious for breast cancer and malignancy has not been ruled out.
