To reduce total cholesterol & LDL-C in patients w/ HoFH as adjunct to diet & other lipid-lowering treatments (eg, LDL apheresis) or alone. To slow or delay progression of atherosclerosis. To reduce total cholesterol, LDL-C & Apo B on childn & adolescents 6-17 yr w/ heterozygous familial hypercholesterolaemia (HeFH).
