METHODS: We conducted two double-blind, randomized, placebo-controlled trials (CORE-TIMI 72a and CORE2-TIMI 72b). Patients with severe hypertriglyceridemia were assigned in a 1:1:1 ratio to receive olezarsen at a dose of 50 mg, olezarsen at a dose of 80 mg, or placebo monthly for 12 months. The primary outcome was the percent change in the triglyceride level at 6 months, reported as the difference between each olezarsen dose group and the placebo group (placebo-adjusted change). Secondary lipid outcomes included the percent change in the triglyceride level at 12 months and in apolipoprotein C-III, remnant cholesterol, and non-high-density lipoprotein (non-HDL) cholesterol at 6 months and 12 months. Acute pancreatitis events were assessed across both trials.
RESULTS: A total of 1061 patients were included in the primary analysis (617 in the CORE-TIMI 72a trial and 444 in the CORE2-TIMI 72b trial). At 6 months, the placebo-adjusted least-squares mean change from baseline in the triglyceride level was -62.9 percentage points in the olezarsen 50-mg group and -72.2 percentage points in the olezarsen 80-mg group in the CORE-TIMI 72a trial and was -49.2 percentage points in the olezarsen 50-mg group and -54.5 percentage points in the olezarsen 80-mg group in the CORE2-TIMI 72b trial (P<0.001 for all comparisons of olezarsen with placebo). Decreases in the levels of triglycerides, apolipoprotein C-III, remnant cholesterol, and non-HDL cholesterol were greater with olezarsen than with placebo (P<0.001 for all comparisons). The incidence of acute pancreatitis was lower with olezarsen than with placebo (mean rate ratio, 0.15; 95% confidence interval, 0.05 to 0.40; P<0.001). The incidence of any adverse events appeared to be similar across trial groups. Elevations in liver-enzyme levels and thrombocytopenia (platelet count, <100,000 per microliter) were more common with the 80-mg dose of olezarsen, and a dose-dependent increase in the hepatic fat fraction was noted.
CONCLUSIONS: Among patients with severe hypertriglyceridemia, treatment with olezarsen led to a significantly greater reduction in the triglyceride level at 6 months and in the incidence of acute pancreatitis than placebo.
