Lomitapide for the treatment of hypertriglyceridemia.

INTRODUCTION: Severe genetic forms of hypertriglyceridemia carry a risk of life-threatening pancreatitis and lack available effective treatments. Lomitapide is a microsomal triglyceride transfer protein inhibitor currently approved for treatment of homozygous familial hypercholesterolemia that may be useful in the management of severe hypertriglyceridemia. Areas covered: Published trials of lomitapide that reported plasma triglyceride response were reviewed, as was a case report of a patient with hypertriglyceridemia who was treated for 13 years with lomitapide. ClinicalTrials.gov was also reviewed for any unpublished results and ongoing trials. Expert opinion: Lomitapide demonstrates effective triglyceride lowering and may be a useful treatment for patients with genetic hypertriglyceridemia and recurrent acute pancreatitis who are refractory to traditional treatment. However, long term hepatic safety may be a concern and direct clinical trial-level data are lacking for this indication.
