Study Summary

The purpose of the study was to evaluate the effect of olezarsen on percent change in fasting triglyceride (TG) levels compared to placebo at Months 6 and 12 and the proportion of participants who achieve different thresholds in fasting TG. Other objectives were to evaluate the effect of olezarsen on percent change in fasting apolipoprotein C-III (apoC-III), very low-density lipoprotein cholesterol (VLDL-C), remnant cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C), HDL-C, total cholesterol (TC), apolipoprotein B (apoB), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein A-1 (apoA-1).
