Altering Lipids for Tolerance of Aromatase Inhibitor Therapy

United States77 participantsStarted 2020-07-28

Plain-language summary

Aromatase inhibitor medications have been approved by the U.S Food and Drug Administration (FDA) for treatment of hormone receptor positive breast cancer. This treatment has been shown to be very effective for treating breast cancer. However, some patients have difficulty tolerating the treatment, and some even decide to stop treatment because of the side effects. Research has shown that over half of patients who had joint pain and stiffness when taking an aromatase inhibitor had an improvement in their symptoms when they took omega-3 fatty acid supplements. This study is being conducted to test whether having patients start to take an omega-3 fatty acid supplement soon after they starting taking an aromatase inhibitor medicine will reduce the likelihood that they will have bothersome symptoms.

Inclusion Criteria * Female subject aged ≥ 18 years who are postmenopausal according to standard clinical criteria or who will have been receiving LHRH agonist therapy for at least 28 days prior to AI initiation. * Stage 0-3 estrogen receptor positive (≥1%) and/or progesterone receptor positive (≥1%) breast cancer, or patients at high risk of developing breast cancer who are planning to initiate AI therapy for chemoprevention. * Planned initiation of aromatase inhibitor therapy (anastrozole, exemestane, or letrozole) for adjuvant treatment of breast cancer or for chemoprevention up to 30 days following baseline visit (ok to initiate screening up to 2 months before planned baseline visit). Concurrent LHRH agonist, anti-HER2 directed therapy (e.g., trastuzumab, pertuzumab, ado-trastuzumab emtansine), and/or CDK4/6 inhibitor therapy (e.g., palbociclib, ribociclib, abemaciclib) is permitted. Prior tamoxifen and/or toremifene is permitted. * Completion of surgery (mastectomy or lumpectomy/partial mastectomy) for treatment of breast cancer. Completion of axillary surgery as indicated (not required). For patients at high risk of breast cancer who have not been diagnosed with breast cancer, no surgery is required. * Completion of chemotherapy, if indicated. Concurrent use of radiation therapy, LHRHa therapy, anti-HER2 therapy, PARP inhibitor, and CDK4/6 inhibitor therapy is permitted. Prior tamoxifen is permitted. * Agree to avoid taking omega-3 fatty acid supplements from sources o…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Change in Percentage of Total Fatty Acids for Each Polyunsaturated Fatty Acid (PUFA) Group From Start of Omega-3 Fatty Acid (O3-FA) Supplementation to 3 Months of O3-FA

Timeframe: From start of Omega-3 Fatty Acid (O3-FA) supplementation to 3 months of O3-FA (at 6 months after start of AI therapy)
