ATLANTIS Trial: Phospholipid Omega-3 Versus Conventional Omega-3

Официальное название

Efficacy of Phospholipid Omega-3 (Ruby-O) Versus Conventional Omega-3 on the Omega-3 Index in Patients With Mixed Dyslipidemia: A 24-Week Randomized, Double-Blind, Parallel Trial

Обзор

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.

Подробное описание

Mixed dyslipidemia is a metabolic condition characterized by elevated triglyceride levels and other lipid abnormalities and is associated with increased residual cardiovascular risk despite standard lipid-lowering therapy. Addressing lipid abnormalities beyond low-density lipoprotein cholesterol may help reduce this residual risk.

The Omega-3 Index is defined as the percentage of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocyte membranes and reflects long-term omega-3 fatty acid exposure and tissue incorporation. Higher Omega-3 Index values have been associated with more favorable cardiovascular risk profiles.

The chemical form of omega-3 fatty acids influences their absorption and bioavailability. Phospholipid-bound omega-3 formulations have demonstrated more efficient intestinal absorption and cellular membrane incorporation compared with conventional triglyceride-based formulations. This study was designed to evaluate whether different dose levels of a phospholipid-based omega-3 supplement result in greater changes in the Omega-3 Index compared with a conventional triglyceride-based omega-3 supplement.

This is a randomized, double-blind, parallel-group clinical trial with three study arms. Eligible participants are adults with mixed dyslipidemia receiving stable statin therapy. Participants are randomly assigned to receive either a phospholipid-based omega-3 supplement at a moderate dose, the same supplement at a higher dose, or a conventional omega-3 supplement in triglyceride form. All study products are administered orally once daily with food for a total duration of 24 weeks.

The primary objective of the study is to compare the Omega-3 Index at week 24 among treatment groups, adjusted for baseline values. Secondary objectives include evaluation of changes in lipid parameters, inflammatory biomarkers, glucose metabolism, anthropometric measures, blood pressure, treatment adherence, and safety outcomes.

The study is conducted in accordance with ethical principles for research involving human participants and has been approved by an institutional ethics committee. Participation is voluntary, and all participants provide written informed consent prior to any study-related procedures.
