Overview

Cardiovascular diseases (CVDs) are the leading cause of global mortality, despite significant advances in prevention and treatment. Atherosclerosis, a chronic inflammatory condition, underlies ischemic events such as infarction and stroke, triggered by the instability and rupture of plaques. Current guidelines recommend drugs primarily aimed at reducing Low-Density-Lipoprotein cholesterol (LDL-C), arterial pressure, and glucose levels for atherosclerosis patients. However, there is little option of approved medications specifically targeting inflammation within the arterial plaques. Consequently, a significant proportion of patients face residual risks. On the contrary, numerous studies have highlighted the anti-inflammatory effects provided by omega-3 fatty acids (n-3 FA), specially the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and their derived oxylipins. These molecules exhibit the ability to enhance the phenotype of macrophages, increasing their capacity for efferocytosis, thereby improving plaque stability. Icosapent ethyl (IPE) is an esterifed version of eicosapentaenoic acid (EPA) and acts as a prodrug in the body to exert its effects. Icosapent ethyl (IPE) was the first fish oil product approved by the US Food and Drug Administration (FDA) to reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in adults. Hence, the hypothesis of this study is that supplementing patients with IPE, in addition to their standard clinical treatment, will enhance macrophage functionality, thereby reducing inflammatory and oxidative stress biomarkers in comparison to a placebo. To test this hypothesis,a Randomized, Double-blind, Placebo-controlled Clinical trial will be performed, in which 294 patients under secondary prevention for CVDs will receive a 6-month supplementation of purified eicosapentaenoic acid-icosapent ethyl (4.0 g) daily or a Placebo (corn oil). Blood samples and anthropometric measurements will be taken at the beginning and end of the period. Basic clinical markers will be assessed, and monocytes will be collected and characterized. Fatty acid profiles and oxylipins will be determined through chromatography coupled with mass spectrometry. Finally, changes in biomarkers for both groups will undergo multivariate analysis to identify characteristics associated with the response to supplementation. Data from this study aims to provide support for physicians considering the prescription of bioactive compounds as a complementary therapy for atherosclerosis, with the goal of reducing residual risks and subsequently decreasing mortality resulting from cardiovascular events.

A Randomized, Double-blind, Parallel, Placebo-controlled Clinical trial will be carried out. Initially, subjects will be randomly assigned to receive the supplementation or placebo treatment for 6 months. Daily supplemental treatment (IPE) will consist of Icosapent Ethy capsules (4.0 g of EPA) taken twice a day (2.0 g/day x 2). Placebo treatment (PLACEBO) will consist of similar capsules containing corn oil instead of IPE. It has been argued that the CV benefit with IPE in certain trials (most notably REDUCEIT) related to the use of pharmaceutical grade mineral oil as comparator (Sherratt et al., 2023). Although a comprehensive review of mineral oil use in CV trials found no reproducible, consistently statistically significant effect of mineral oil on inflammatory markers, including hsCRP (Olshansky et al., 2020), the investigators opted for use of corn oil as placebo, while there is no consensus about this subject. Participants will be instructed to consume half capsules after lunch and half after dinner. During the trial, the subjects will maintain their habitual routine and diet. Prescribed drugs will be kept without any change throughout the study. The Icosapent-ethyl (IPE) will be purchased from BASF S.A., Avenida Nacoes Unidas, 14171, 04794-000 Sao Paulo, Brazil, and the oil will be encapsulated in a Brazilian company still not defined.

Outcomes

Primary Outcomes

Eicosapent ethyl ester (IPE) and high sensitivity C-Reactive Protein (hs-CRP)

Eicosapent ethyl ester (IPE) combined with a classical pharmacological treatment, will contribute to reduce high sensitivity C-Reactive Protein (hs-CRP) in patients undergoing secondary prevention for cardiovascular disease. the concentration hsCRP was chosen based on the fact that it is the only inflammatory marker mentioned in the Prevention Guidelines (Arnett et al., 2019), was selected in the "Cantos" study (Ridker et al., 2018), has shown correlation with IPE in the "REDUCE-IT" study (Bhatt et al., 2019) and also having observed a reduction in patients supplemented with fish oil in other studies (Scolaro et al., 2018; Elisia et al., 2022).
