Summary
This study tested a drug called olezarsen in 154 adults with high triglycerides (a type of blood fat) and either heart disease or very high triglycerides. Participants received injections of the drug or a placebo for up to 12 months. The main goal was to see if the drug could lower triglyceride levels more than placebo.
