EPA and DHA for Lipid Disorders
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to understand how two different fish oils, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), affect people with high cholesterol. Participants will be randomly assigned to take either EPA or DHA supplements and must maintain a 28-day food and activity log. Those with high cholesterol and triglycerides, low "good" cholesterol (HDL), and who consume less than three servings of fatty fish per week might be suitable candidates. Participants will visit the clinic three times for tests and blood collection. As an Early Phase 1 trial, this research focuses on understanding how these fish oils work in people, offering participants a chance to contribute to groundbreaking research.
Will I have to stop taking my current medications?
The trial requires that you do not take daily aspirin, NSAIDs (non-steroidal anti-inflammatory drugs), anticoagulants (blood thinners), or corticosteroids. If you are on these medications, you would need to stop them to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study showed that DHA (docosahexaenoic acid) is very safe. It did not affect antioxidant levels, blood clotting, or liver function. However, taking more than 3 grams a day might slow blood clotting. The amount used in this study is much lower, reducing this risk.
Research on EPA (eicosapentaenoic acid) has shown it to be well-tolerated and approved by the FDA for reducing heart disease risk. Both EPA and DHA are omega-3 fatty acids found in fish oil, which help manage cholesterol and support heart health.
Overall, both treatments are generally safe and have been used by many people. If there are concerns, consulting a healthcare provider is advisable.12345Why are researchers excited about this trial's treatments?
Most treatments for lipid disorders focus on medications like statins that lower cholesterol by inhibiting certain liver enzymes. But DHA and EPA, the active ingredients in the trial, offer a unique approach by being omega-3 fatty acids that can help reduce triglycerides and improve overall heart health. Unlike traditional medications, these supplements are derived from fish oils and may have fewer side effects. Researchers are excited because DHA and EPA might not only lower lipid levels but also provide additional anti-inflammatory benefits, making them a promising alternative or complement to existing therapies.
What evidence suggests that this trial's treatments could be effective for lipid disorders?
This trial will compare the effects of DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) on lipid disorders. Research has shown that DHA can help manage cholesterol by enlarging LDL (low-density lipoprotein) particles and improving fat processing, potentially leading to better cholesterol control for those with high levels. Additionally, DHA consistently lowers triglycerides, which are fats in the blood.
Participants in the DHA group will receive a DHA supplement regimen. Evidence suggests that EPA can lower the risk of heart problems, especially for people already taking statins (medications that lower cholesterol). High doses of EPA are particularly effective in reducing the risk of heart-related issues. Participants in the EPA group will receive an EPA supplement regimen. However, low doses of mixed omega-3s appear less effective, highlighting the importance of proper dosing to achieve the desired effects.14678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for adults with high triglycerides and cholesterol who can follow a low fatty fish diet (<3 servings per week). They must have LDL-C levels between 40-130 mg/dL, fasting TG levels of 150-500 mg/dL, and HDL-C ≤ 40 (men) or ≤ 50 (women), and be able to consent to the study.Inclusion Criteria

Trial Overview
The study tests the effects of two omega-3 fatty acids, EPA and DHA, on blood lipids and platelets in patients with lipid disorders. Participants will visit the clinic three times for checkups, tests, blood collection, and will be randomly assigned to either EPA or DHA supplements.

Treatment groups
Experimental Treatment
Participants will receive EPA supplement. 2 gelcaps, two times per day with meals (breakfast and dinner). 1 gelcap consists of 1 gram of EPA. Participants will be given 28-day food and activity log.
Participants will receive DHA supplement. 3 gelcaps, three times per day with meals (breakfast, lunch, and dinner). DHA supplement regimen contains 450 mg DHA and minimal EPA (60 mg) per pill. Participants will be given 28-day food and activity log.
