A Study of Olezarsen (ISIS 678354) Administered to Participants With Severe Hypertriglyceridemia

Phase 3
Active, not recruiting
Conditions
Severe Hypertriglyceridemia
Interventions
Drug: Placebo
Registration Number
NCT05079919
Lead Sponsor
Ionis Pharmaceuticals, Inc.
Brief Summary

The purpose of the study is to evaluate the efficacy of olezarsen as compared to placebo on the percent change in fasting triglycerides (TG) from baseline.

Detailed Description

This is a multi-center, randomized, double-blind, placebo-controlled study in 617 participants. Participants will be randomized to receive olezarsen or placebo in a 53-week treatment period. The length of participation in the study will be approximately 78 weeks, which includes an up to 12-week screening period, a 53-week treatment period, and a 13-week post-treatment evaluation period or transition to open-label extension (OLE) study with up to 1-year treatment.

Recruitment & Eligibility

ACTIVE_NOT_RECRUITING
Sex
All
Target Recruitment
617
Inclusion Criteria
  • Fasting TG ≥ 500 mg/dL (5.65 mmol/L) at Screening and Qualification
  • Patients must be on lipid-lowering therapy that should adhere to standard of care (SOC) per local guidelines. Lipid-lowering medications should be optimized and stabilized for at least 4 weeks prior to Screening to minimize changes in these medications during the study.

Key

Exclusion Criteria
  • Hemoglobin A1c (HbA1c) ≥ 9.5% at Screening
  • Alanine aminotransferase or aspartate aminotransferase > 3.0 × upper limit of normal
  • Total bilirubin > upper limit of normal unless due to Gilbert's syndrome
  • Estimated GFR < 30 mL/min/1.73 m^2
