Abstract
Homozygous familial hypercholesterolemia is a genetic disorder characterized by low-density lipoprotein (LDL)-receptor dysfunction, markedly elevated levels of LDL-cholesterol (LDL-C) and premature atherosclerosis. Patients are often poorly responsive to conventional lipid-lowering therapies that upregulate LDL-receptor expression. Lomitapide inhibits microsomal triglyceride transfer protein, which lipidates nascent apolipoprotein (apo)B-containing lipoproteins. In a pivotal 78-week openlabel trial, lomitapide, titrated to the maximal tolerable dose, decreased LDL-C by 50% at the end of the efficacy phase (week 26) in patients with homozygous familial hypercholesterolemia.2 The principal adverse events included gastrointestinal disturbances, hepatic enzyme elevations, and increased liver fat. Here we provide additional long-term efficacy and safety data, including an exploratory analysis of the potential metabolic consequences of hepatic fat accumulation from an extension trial (NCT00943306).I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
