Brief Summary:

Primary objective:

Determine whether mipomersen (ISIS 301012) significantly reduces atherogenic lipid levels in patients with severe heterozygous familial hypercholesterolemia (severe HeFH), defined as low-density lipoprotein cholesterol (LDL-C) levels ≥200 mg/dL plus the presence of coronary heart disease (CHD)/risk equivalents or LDL-C levels ≥300 mg/dL regardless of the presence of CHD/risk equivalents (referred to as Cohort 1) compared to placebo. Two different mipomersen dosing regimens will be studied: subcutaneous (SC) mipomersen 200 mg once weekly versus placebo, and SC mipomersen 70 mg thrice weekly versus placebo.

Secondary Objectives:

  • Determine whether there are qualitative differences between the safety profiles of the 2 dosing regimens and placebo in Cohort 1, patients with HeFH with LDL-C levels ≥160 mg/dL and <200 mg/dL plus the presence of CHD/risk equivalents (referred to as Cohort 2), and the overall study population
  • Determine whether there are qualitative differences between the tolerability of the 2 dosing regimens and placebo in Cohort 1, Cohort 2, and the overall study population
  • Further characterize the pharmacokinetics (PK) of the 2 dosing regimens in Cohort 1, Cohort 2, and the overall study population
  • Determine whether the 2 mipomersen dosing regimens significantly reduce atherogenic lipid levels in Cohort 2 compared to placebo
  • Obtain additional data regarding ongoing safety and efficacy of mipomersen in patients with FH and inadequately controlled LDL-C who complete the primary efficacy assessment visit (PET) in the Blinded Treatment Period and continue treatment in Open-Label Continuation Period

Condition or disease Intervention/treatment Phase
Hypercholesterolemia Heterozygous Familial Drug: mipomersen sodium 200 mg Drug: Placebo Drug: mipomersen sodium 70 mg Phase 3

Detailed Description:

The study consisted of a Screening period of up to 4 weeks, Blinded Treatment Phase of 60 weeks, Open-Label Continuation Period of 26 weeks, and Post-Treatment Phase of 24 weeks.

Study Design, masking - Study treatment was blinded (double-blinded) through the Primary Efficacy Assessment Visit in the Blinded Treatment Period. Study treatment was open-label in the Open-Label Continuation Period.

Primary Outcome Measures :
  1. Percent Change From Baseline To Primary Endpoint Visit (PET) In LDL-C In Cohort 1 [ Time Frame: Baseline and Week 61 ]
    The percent change from baseline to PET in LDL-C was measured in Cohort 1, which included participants with severe heterozygous familial hypercholesterolemia (HeFH). Severe HeFH was defined as LDL-C levels ≥200 mg/deciliter (dL) plus the presence of coronary heart disease (CHD)/risk equivalents or LDL-C levels ≥300 mg/dL regardless of the presence of CHD/risk equivalents.


Secondary Outcome Measures :
  1. Percent Change From Baseline To PET In LDL-C In Cohort 2 [ Time Frame: Baseline, PET (up to 60 weeks) ]
    The percent change from baseline to PET in LDL-C was measured in Cohort 2, which included participants with HeFH with LDL-C levels ≥160 mg/dL and <200 mg/dL, plus the presence of CHD/risk equivalents.

  2. Percent Change From Baseline To PET In Apolipoprotein B (Apo B) In Cohort 1 [ Time Frame: Baseline and Week 61 ]
    The percent change from baseline to PET in Apo B was measured in participants in Cohort 1 with HeFH during the Blinded Treatment Period.

  3. Percent Change From Baseline To PET In Apolipoprotein B (Apo B) In Cohort 2 [ Time Frame: Baseline and Week 61 ]
    The percent change from baseline to PET in Apo B was measured in participants in Cohort 2 with HeFH during the Blinded Treatment Period.

  4. Percent Change From Baseline To PET in Lipoprotein (a) In Cohort 1 [ Time Frame: Baseline and Week 61 ]
    The percent change from baseline to PET in Lipoprotein A1 was measured in participants in Cohort 1 with HeFH during the Blinded Treatment Period.

  5. Percent Change From Baseline To PET in Lipoprotein (a) In Cohort 2 [ Time Frame: Baseline and Week 61 ]
    The percent change from baseline to PET in Lipoprotein A1 was measured in participants in Cohort 2 with HeFH during the Blinded Treatment Period.
