Olezarsen, formerly known as IONIS-APOCIII-LRx and AKCEA-APOCIII-LRx, is an investigational ligand-conjugated antisense (LICA) medicine designed to inhibit the production of apoC-III for patients who are at risk of disease due to elevated triglyceride levels.
ApoC-III is a protein produced in the liver that regulates triglyceride metabolism in the blood. People with severely elevated triglycerides, such as people with FCS, are at high risk for acute pancreatitis and an increased risk of cardiovascular disease, or CVD. It is estimated that FCS affects one to two individuals per million worldwide and more than three million patients have severe hypertriglyceridemia in the U.S.
Safety and efficacy have not been evaluated by any regulatory authorities for the indications described.
