Summary

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

Description

This is a Phase 3, multi-center, randomized, double-blind, placebo-controlled study in up to approximately 390 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.

The Screening Period was extended with no impact to overall study timelines. Endpoints added to provide assessment on the pancreatitis rate after olezarsen reaches steady state levels.
