ATLANTIS Trial: Phospholipid Omega-3 Versus Conventional Omega-3
Colombia105 participantsStarted 2026-03
Plain-language summary
This study is a clinical trial designed to compare two forms of omega-3 supplements in adults with mixed dyslipidemia. Mixed dyslipidemia is a condition in which blood fat levels, such as triglycerides and cholesterol, are not within the recommended range and may increase the risk of cardiovascular disease.
Participants in this study will be randomly assigned to receive one of three study products: a phospholipid-based omega-3 supplement (Ruby-O) at a moderate dose, the same phospholipid-based omega-3 supplement at a higher dose, or a conventional omega-3 supplement in triglyceride form. All study products will be taken by mouth once daily with food for 24 weeks.
The main goal of the study is to evaluate changes in the Omega-3 Index, a blood test that reflects the amount of omega-3 fatty acids incorporated into red blood cell membranes. Additional goals include evaluating changes in blood lipid levels, markers of inflammation, blood sugar metabolism, body weight, blood pressure, treatment adherence, and safety.
This study is sponsored by the Fundación del Caribe para la Investigación Biomédica and is conducted in adults who are receiving stable statin therapy. Participation in the study is voluntary, and all participants may withdraw at any time.

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?

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.
