Abstract
Homozygous familial hypercholesterolemia (HoFH) is an autosomal codominant disorder manifested by high concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol, and premature cardiovascular disease. Despite conventional lipid-lowering therapy, LDL cholesterol levels remain elevated in patients with HoFH; these patients are considered to be at high risk for cardiovascular events. In 2012-2013, two drugs with novel mechanisms of action were approved by the US Food and Drug Administration for the treatment of HoFH: lomitapide mesylate and mipomersen. Both of these treatments reduce total cholesterol, LDL cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, lipoprotein a, and triglyceride levels. This review describes the clinical tradeoffs in efficacy and hepatotoxicity of these drugs in two cases of HoFH.
