Design and rationale of the CORE-TIMI 72a and CORE2-TIMI 72b trials of olezarsen in patients with severe hypertriglyceridemia.
Article in American heart journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
backgroundSevere hypertriglyceridemia (HTG), defined as a serum triglyceride (TG) concentration ≥500 mg/dl, is present in approximately 1 in every 100 individuals and carries direct clinical consequences, including pancreatitis, which can be life-threatening. Olezarsen is an investigational antisense oligonucleotide targeted to the mRNA for apolipoprotein C-III (apoC-III), a protein known to impair TG clearance by inhibiting lipoprotein lipase and the hepatic uptake of triglyceride-rich remnants. No dedicated trial has tested olezarsen in patients with severe HTG.
methodsIn these 2 pivotal phase 3 trials, CORE-TIMI 72a and CORE2-TIMI 72b, patients with severe HTG were randomized in a 2:1 fashion to either olezarsen (80 mg or 50 mg dose) or matching placebo. Patients will be treated for a total of 12 months and evaluated for the primary endpoint of percent change in TGs from baseline to 6 months compared with placebo. Pooled analyses of CORE and CORE2 will also assess olezarsen's effect on acute pancreatitis events and change in hepatic steatosis.
resultsA total of 617 subjects in CORE-TIMI 72a and 446 subjects in CORE2-TIMI 72b were randomized. In these 2 trials, the median age was 54 and 55 years, women made up 24% and 23% of the study population, and the baseline TGs were 836 mg/dl and 749 mg/dl, respectively. A total of 333 subjects, 129 from CORE-TIMI 72a and 204 from CORE2-TIMI 72b, were enrolled in the hepatic MRI substudy. DISCUSSION: Together, CORE-TIMI 72a and CORE2-TIMI 72b are designed to establish the efficacy and safety of olezarsen in patients with severe HTG.
