Weight Loss Plus Omega-3 Fatty Acids or Placebo in High Risk Women

January 6, 2022 updated by: Carol Fabian, MD

Randomized Pilot Trial of Omega-3 Fatty Acids or Placebo in Peri- or Post-Menopausal Women at High Risk for Breast Cancer Undergoing a Weight Loss Intervention

The purpose of this study is to determine if high dose supplementation with the omega-3 fatty acids EPA and DHA, when added to a weight loss program, is well tolerated in the study population and if there is an increase in the favorable change in blood and tissue breast cancer risk factors when compared to weight loss alone.

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

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

45 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Weight Loss + Omega-3 FA
Participants will be instructed to follow a diet that is reduced by 500-700 kcal/day below maintenance requirements for 24 weeks or until the individual has reached a BMI of 25kg/m2 (generally 1000-2000 calories/day). Participants will be given one capsule of Omega-3 FA (fatty acids) a day beginning 2 weeks after starting their diet and exercise routine. Omega-3 FA will be increased by 1 capsule/day or every other day until participant is taking 5 capsules per day.Each Amber 4020 Ethyl Ester (EE) 1000 mg omega-3 capsule contains 420 mg of EPA and 210 mg of DHA both as the ethyl esters (380 mg EPA and 190 mg DHA)
