Brief summary

The purpose of this study is to determine safety and efficacy of mipomersen (ISIS 301012) in the reduction of total cholesterol, low density lipoprotein cholesterol (LDL-C), and apolipoprotein B (apoB) in high risk subjects intolerant to statins.

Detailed description

In humans, apoB is the principal apolipoprotein of the atherogenic lipoproteins, comprising very low-density lipoprotein (VLDL), intermediate density lipoprotein (IDL) and low density lipoprotein (LDL). ApoB messenger ribonucleic acid (mRNA) is abundantly present in the liver. Within the endoplasmatic reticulum, apoB requires lipidation by microsomal triglyceride transfer protein, which allows apoB to be incorporated in the VLDL particle within the lumen of the endoplasmatic reticulum. Non-lipidated apoB is readily degraded via ubiquitination. Notably, apoB within the VLDL particle is obligatory for hepatic secretion of VLDL. ApoB remains present within the VLDL-metabolism pathway, from secretion to clearance of the end product LDL by the liver LDL receptor. As a consequence, apoB reliably reflects the total burden of atherogenic lipoproteins. Thus, apoB carries strong prognostic value for cardiovascular events, which exceeds the predictive value of LDL-C. Conversely, decreased levels of apoB (e.g. in familial hypobetalipoproteinemia) have been associated with reduced levels of atherosclerosis. These genetic observations have prompted interest in pharmacologic inhibition of apoB synthesis. Mipomersen (ISIS 301012) is an antisense drug targeted to human apoB, the principal apolipoprotein of LDL and its metabolic precursor, VLDL. Mipomersen (ISIS 301012) is complementary to the coding region of the mRNA for apoB, binding by Watson and Crick base pairing. The hybridization (binding) of mipomersen (ISIS 301012) to the cognate mRNA results in Ribonuclease (RNase) H-mediated degradation of the cognate mRNA, thus inhibiting translation of the apoB protein. This was a randomized, double-blind, placebo-controlled Phase 2 study to assess the safety and efficacy of mipomersen administration in high-risk statin-intolerant patients with hypercholesterolemia. This study consisted of a ≤3-week screening period, 26 weeks of treatment, and a 24-week post-treatment follow-up period. Eligible patients were randomized in a 2:1 ratio to receive mipomersen 200 mg or matching volume placebo subcutaneous (SC) injections weekly. Following the screening visit, eligible patients returned to the study center for clinical evaluation every week for study drug administration and assessments.

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.

Summary of Participants With Adverse EventsPre-treatment (prior to first dose), On-treatment (Day 1 to week 28), Post-treatment (Week 28-52)The on-treatment time frame spanned the time during which the study drug was administered until the later of the primary efficacy time point and 14 days beyond the last study drug date. Adverse events (AEs) were considered related if assessed by the Investigator as possibly, probably or definitely related to study drug. Severity was assessed as: * Mild-symptom barely noticeable to the patient or do not make the patient uncomfortable; * Moderate-symptom makes the patient uncomfortable, affects performance of daily activities; * Severe-symptom causes the patient severe discomfort, may cause cessation of treatment with the study drug. Serious AEs (SAEs) are those that resulted in death, were life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly, or resulted in an important medical event that may have jeopardized the patient or required medical or surgical intervention.

Percent Change From Baseline in Apolipoprotein A1 at the Primary Efficacy Time Point

Apolipoprotein A1 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.

Time frame: 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).

Population: The Full Analysis Set, which consisted of all randomized patients who received at least 1 injection of study drug (mipomersen or placebo) and with a valid baseline and at least 1 post-baseline LDL-C measurement.
