Objectives

Narrative objectives1

This study evaluates the effects of switching from a conventional EPA formulation to a self-emulsifying high-purity EPA formulation on atherosclerosis markers and peripheral nerve function in patients with dyslipidemia, using a six-month before-and-after comparison.

Basic objectives2

Others

Basic objectives -Others

Eicosapentaenoic acid ethyl ester (EPA) is widely used in the treatment of dyslipidemia and peripheral circulatory disorders, and its anti-atherosclerotic effects have been reported. However, conventional formulations have limitations in absorption and require multiple daily doses. To address these issues, a self-emulsifying high-purity EPA formulation has been developed. This new formulation offers improved absorption and the convenience of once-daily dosing, which is expected to enhance patient adherence. The present study aims to investigate the effects of switching from conventional EPA formulations to this new formulation on atherosclerosis risk and peripheral nerve function.

Interventions/Control_1

In this study, patients will switch from a conventional EPA formulation to a self-emulsifying high-purity EPA formulation (2 g once daily) and continue the treatment for six months.
Evaluations will be conducted at two time points: before the switch and six months after the switch.

The primary endpoint will be the change in brachial-ankle pulse wave velocity (baPWV), an indicator of atherosclerosis and peripheral circulation.

Secondary endpoints will include changes in serum lipid parameters (LDL-C, HDL-C, triglycerides, and non-HDL-C), subjective assessments of symptoms such as cold sensation, numbness, and pain, as well as evaluation of diabetic peripheral neuropathy using the DPN Check device and assessment of heart rate variability (CVR-R) on electrocardiography, to investigate the effects on autonomic and peripheral nerve function.
