- •We describe the first use of lomitapide in a HoFH child for 4 years.
- •20 mg/d lomitapide added extra 37% reduction in LDL-C.
- •Lomitapide was well tolerated.
- •Despite treatment carotid and aortic valve disease progressed.
We report for the first time the efficiency and safety of a 49-month compassionate use of the microsomal transfer protein inhibitor lomitapide in a child with homozygous familial hypercholesterolemia. On average, 20 mg of lomitapide caused a 37% reduction in low-density lipoprotein cholesterol levels on top of ezetimibe and atorvastatin. The drug was well tolerated with no changes in liver enzymes and occurrence of steatosis on hepatic ultrasound. The patient presented adequate growth and sexual maturation. Nonetheless, there was progression in either subclinical atherosclerotic carotid or aortic valve diseases. Further studies are necessary to test the impact and safety of lomitapide in children with homozygous familial hypercholesterolemia.
