Description

ETC-588, or LUV (large unilamellar vesicles), is made of naturally occurring lipids that circulate through arteries to facilitate the role of high-density lipoprotein (HDL) in removing accumulated cholesterol and other lipids from cells including those in the arterial wall. LUV are capable of transporting excess cholesterol from the vasculature to the liver for eventual elimination as part of the reverse lipid transport (RLT) pathway. It is believed that the removal of cholesterol by ETC-588 through this pathway may result in the reversal of atherosclerosis. Esperion is currently developing ETC-588 as a treatment for patients with acute coronary syndromes.

Pharmacology

Indication

Investigated for use/treatment in atherosclerosis, coronary artery disease, and vascular diseases.

Pharmacodynamics

ETC-588, or LUV (large unilamellar vesicles), is made of naturally occurring lipids that circulate through arteries to facilitate the role of high-density lipoprotein (HDL) in removing accumulated cholesterol and other lipids from cells including those in the arterial wall. LUV are capable of transporting excess cholesterol from the vasculature to the liver for eventual elimination as part of the reverse lipid transport (RLT) pathway.

Mechanism of action

ETC-588 is a phospholipid bilayer that can sequester cholesterol. Once the HDL particle, which is small enough to enter the arterial wall, pulls the cholesterol out of the plaque, it readily hands the cholesterol over to the LUV. The LUV then transports the cholesterol to the liver for processing.
