Study Endpoints

Primary Endpoints

Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at Primary Efficacy Time Point
Baseline (the average of the screening and Day 1 pre-treatment assessments) and the Primary Efficacy Time point (PET) up to week 28

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.

Summary of Participants With Adverse Events
Pre-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.

Change From Baseline in Liver Triglyceride (TG) Content As Measured by Magnetic Resonance Spectroscopy (MRS)
Baseline, Day 26, Day 99

Localized proton MRS was used to quantify liver TG concentration. All MRS imaging of the liver was performed using the same 1.5T scanner. The instructions were to cover the entire liver (from just above the dome to just below the inferior tip) using a qualified imaging technique (Yokoo, 2009, Radiology). Liver fat quantification was performed by determining the liver fat fraction (%) derived from MRS using selected Regions of Interest (ROI). The analyst typically looked for the branching of the right portal vein and mapped slices from one scan to the next. There were typically 2 ROIs in the right lobe and 1 in the left lobe. Magnetic resonance spectroscopy imaging ROIs between different scans were selected using anatomical landmarks for both time points.

Frequently asked questions about Mipomersen

What is Mipomersen used for?

Mipomersen is an investigational small molecule being developed for cardiovascular conditions, including heterozygous familial hypercholesterolemia, hypercholesterolemia, and lipid metabolism disorders. It has been studied in healthy volunteers and in patients with these metabolic diseases. The drug is administered via subcutaneous injection and is currently in Phase 3 clinical development.

Who makes Mipomersen?

Mipomersen is being developed by Ionis Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol IONS. The company has conducted clinical trials evaluating the drug's safety, efficacy, and pharmacokinetics in various patient populations and healthy volunteers.

What phase is Mipomersen in?

Mipomersen is in Phase 3 clinical development. It has completed four clinical trials, including Phase 1 and Phase 2 studies. The drug is investigational and has not been approved by regulatory authorities. All completed trials were randomized, double-blind, and placebo-controlled, with a total enrollment of 254 participants.

What clinical trials is Mipomersen in?

Mipomersen has completed four clinical trials. NCT00707746 was a Phase 2 study in high-risk statin-intolerant subjects with hypercholesterolemia. NCT01061814, NCT01090661, and NCT01299298 were Phase 1 studies in healthy volunteers, including a cardiac repolarization study and a pharmacokinetic study in Japanese healthy volunteers.

How does Mipomersen work?

Mipomersen is an antisense oligonucleotide that targets apolipoprotein B-100, a key protein involved in lipid metabolism. By inhibiting the production of this protein, the drug aims to reduce levels of atherogenic lipoproteins, including LDL cholesterol. This mechanism is relevant for treating conditions like familial hypercholesterolemia and other lipid metabolism disorders.
