AbstractHomozygous familial hypercholesterolemia (HoFH) is associated with severe hypercholesterolemia and premature cardiovascular morbidity and mortality. The most frequent cause of HoFH is loss of function mutations in the gene for the low-density lipoprotein receptor, resulting in reduced clearance of low-density lipoprotein (LDL) cholesterol from the circulation. Patients with HoFH have attenuated responsiveness to lipidlowering therapies such as statins, cholesterol absorption inhibition, and bile acid binding resins because of impaired LDL receptor expression. Lomitapide is a novel microsomal triglyceride transfer protein inhibitor that does not depend on the ability to upregulate LDL receptors on the surface of hepatocytes. Lomitapide reduces production of apolipoprotein B-containing lipoproteins, significantly reduces serum levels of LDL cholesterol, and is approved for use in patients with HoFH in the United States and the European Union.
