About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Study to Assess Efficacy and Safety of ISIS 301012 as Add-on Therapy in Heterozygous Familial Hypercholesterolemia Subjects With Coronary Artery Disease

The purpose of this study is to determine whether mipomersen safely and effectively lowers low-density lipoprotein cholesterol (LDL-C) in patients with Heterozygous Familial Hypercholesterolemia (HeFH) and coronary artery disease (CAD) who are already on a stable dose of other lipid-lowering agents (including maximally tolerated statin therapy).

Read the detailed description

Familial hypercholesterolemia (FH) is an autosomal dominant genetic disorder of lipoprotein metabolism characterized by markedly elevated LDL-C, premature onset of atherosclerosis and development of xanthomata. Patients with heterozygous familial hypercholesterolemia typically have total plasma cholesterol between 350 to 550 mg/dL and disease onset in their third and fourth decade.

Mipomersen (ISIS 301012) 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 (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.

This study consisted of a 26-week treatment period and a 24-week post-treatment follow-up period (with the exception of patients who enrolled in the open-label extension study [Study 301012-CS6; NCT00694109]). The treatment period spanned the time during which the study treatment was administered until the later of the primary efficacy time point (PET) or 14 days beyond the last day of study drug administration. The post-treatment follow-up period began the day after completion of the treatment period and ended on the day of the patient's last contact date within the study.

Following treatment and Week 28 evaluations, eligible patients who tolerated study drug could elect to enroll in an open-label extension study (301012-CS6). Patients who were not eligible for or who elected not to enroll in the open-label extension study and patients who discontinued during the 26-week treatment period were followed in this study for an additional 24 weeks from administration of the last dose of study drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at the Primary Efficacy Time Point

    LDL cholesterol 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. The primary efficacy time point was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  2. LDL Cholesterol at Baseline and at the Primary Efficacy Time Point

    The primary efficacy time point (PET) was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

Secondary outcomes (6)
  1. Percent Change From Baseline in Apolipoprotein B at the Primary Efficacy Time Point

    Apolipoprotein B was measured in mg/dL. Samples were taken following an overnight fast. The primary efficacy time point was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  2. Apolipoprotein B at Baseline and at the Primary Efficacy Time Point

    The primary efficacy time point (PET) was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  3. Percent Change From Baseline in Total Cholesterol at the Primary Efficacy Time Point

    Total cholesterol was measured in mg/dL. Samples were taken following an overnight fast. The primary efficacy time point was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  4. Total Cholesterol at Baseline and at the Primary Efficacy Time Point

    The primary efficacy time point (PET) was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  5. Percent Change From Baseline in Non-High-Density Lipoprotein Cholesterol at the Primary Efficacy Time Point

    Non-high-density lipoprotein cholesterol was measured in mg/dL. Samples were taken following an overnight fast. The primary efficacy time point was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).

  6. Non-High-Density Lipoprotein Cholesterol at Baseline and at the Primary Efficacy Time Point

    The primary efficacy time point (PET) was the post-baseline visit closest to 14 days after the last dose of study treatment.

    Measured: Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET; Week 28 or the post-baseline visit closest to 14 days after the last dose).
