The current treatment strategies for managing dyslipidemia focus on reducing low-density lipoprotein cholesterol (LDL-C) to minimize the risks of atherosclerosis and myocardial infarction (MI).

Although statin therapy has been the primary treatment for dyslipidemia, HoFH patients do not respond well to statins, requiring alternative therapies. Microsomal triglyceride transfer protein (MTP) inhibition has emerged as a potential therapeutic target for treating HoFH. MTP is primarily responsible for transferring triglyceride and other lipids into apolipoprotein B (ApoB) during the assembly of very low-density lipoprotein (VLDL) particles in the liver. Lomitapide, an inhibitor of MTP, has been approved for treatingof HoFH adults. Unlike statins, lomitapide does not act on the LDLr to reduce cholesterol. Instead, lomitapide lowers the levels of ApoB-containing proteins, primarily VLDL, eventually decreasing LDL-C levels. Studies have shown that lomitapide can reduce LDL-C levels by more than 50% in patients with HoFH who have failed to respond adequately to other treatments.
