Lipid Disorders


Amarin's therapeutic focus is on lipid disorders, currently hypertriglyceridemia and mixed dyslipidemia.

Triglyceride is fat and, like cholesterol, is a type of lipid in the blood. Triglyceride is carried through the body with cholesterol, on the same lipoproteins. Hypertriglyceridemia refers to a condition in which patients have high levels of triglycerides in the bloodstream. Triglyceride levels provide unique information as a biomarker of heart health associated with the risk for cardiovascular disease.

We refer to mixed dyslipidemia as a condition in which patients have a combination of two or more lipid abnormalities, including elevated triglycerides and low levels of high-density lipoprotein cholesterol, or HDL-C (often referred to as "good" cholesterol), and/or elevated low-density lipoprotein cholesterol or LDL-C (often referred to as "bad" cholesterol). The risk of cardiovascular disease is thought to be higher when an individual has low HDL-C and elevated levels of LDL-C. Non-HDL cholesterol (Non-HDL-C) refers to all kinds of cholesterol other than HDL-C. Generally, a person's risk for cardiovascular disease is thought to be lower the lower that person's levels of non-HDL-C.[1]

Cardiovascular disease encompasses many different diseases with patients often suffering from multiple conditions. The risks of cardiovascular disease include heart attacks, strokes, and other cardiovascular events. A healthy diet and exercise are recommended to reduce the risk of cardiovascular disease. After diet and exercise, statin therapy is recommended as the standard of care to reduce the risk of cardiovascular disease. Statin therapy is primarily targeted at lowering high levels of LDL-C, a recognized surrogate for cardiovascular risk. In clinical studies, statin therapy reduces cardiovascular risk by approximately one third.[2] Thus, after statin therapy, there remains a large unmet clinical need for further reduction in cardiovascular risk.

Hypertriglyceridemia and mixed dyslipidemia are being studied for their potential links as causal factors for cardiovascular disease. Scientific evidence is currently inconclusive as to whether lowering triglyceride and non-HDL-C levels in patients who have mixed dyslipidemia and are treated with statin therapy ultimately reduces the risks associated with cardiovascular disease, such as a patient's risk of a having a heart attack or stroke.[3]

Events caused by cardiovascular disease are the leading cause of death and disability among men and women in Western societies. The U.S. Department of Health and Human Services reported that the number of deaths due to heart disease during the 2011–2014 period were over 614,000 per year, more than cancer or any other individual cause of death [4]. It is estimated that total global pharmaceutical sales in the cardiovascular segment in 2010 were approximately $116.3 billion.[5]

It is estimated that approximately 40 million adults in the United States have high triglyceride levels ≥200mg/dL.[1,6,7] It is estimated that approximately 70 million adults in the United States have elevated triglyceride levels ≥150mg/dL.[6,8] In the United States, mean triglyceride levels have risen since 1976 in concert with the growing epidemic of obesity, insulin resistance, and type 2 diabetes mellitus (T2DM).[1,9] In contrast, mean LDL-C levels have receded due to aggressive pharmacologic and dietary therapy.[9] It is estimated that the worldwide number of people with high and elevated triglyceride levels is at least three times the levels in the United States.[9]

It is estimated that approximately 4 million adults in the United States have severe (≥500 mg/dL) hypertriglyceridemia.[1,6] Patients with severe hypertriglyceridemia are also thought to be at risk for pancreatitis, a potentially life-threatening condition.[10]

The effect of drugs and drug candidates under development at Amarin on the risks of cardiovascular disease and pancreatitis has not been determined.
