Primary Outcome Measures

Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at Primary Efficacy Time Point
LDL-C was measured in mg/dL. Samples were taken following an overnight fast. For patients with triglycerides <400 mg/dL, LDL-C was obtained using Friedewald's calculation; and for patients with triglycerides >=400 mg/dL, LDL-C was directly measured by the central laboratory using ultracentrifugation. Baseline was defined as the average of the screening and Study Day 1 (pre-treatment) assessments. An assessment was not included in this calculation if it was associated with a non-fasting blood draw or was drawn more than 4 weeks prior to Study Day 1. The PET was the post-baseline visit, for which LDL-C was assessed, closest to 14 days after the last dose of study drug.
LDL-C at Baseline and the Primary Efficacy Time Point (PET)
The PET was the post-baseline visit, for which LDL-C was assessed, closest to 14 days after the last dose of study drug.

5. Study Description

Brief Summary
The purpose of the study is to evaluate the safety and efficacy of dosing with mipomersen for 26 weeks in treating severely hypercholesterolemic patients who are on a maximally tolerated lipid-lowering regimen and who are not on apheresis.
Detailed Description
Hypercholesterolemia is characterized by markedly elevated low density lipoproteins (LDL). Elevated LDL is a major risk factor for coronary heart disease (CHD). Mipomersen is an antisense drug that reduces a protein in the liver cells called apolipoprotein B (Apo-B). Apo-B plays a role in producing low density lipoprotein cholesterol (LDL-C) (the "bad" cholesterol) and moving it from the liver to one's bloodstream. High LDL-C is an independent risk factor for the development of coronary heart disease (CHD) or other diseases of blood vessels. It has been shown that lowering LDL-C reduces the risk of heart attacks and other major adverse cardiovascular events. The purpose of this study is to determine whether mipomersen safely and effectively lowers LDL-C in severely hypercholesterolemic patients who are on a maximally tolerated lipid-lowering regimen and who are not on apheresis.
