Abstract

Olezarsen has shown efficacy in hypertriglyceridemic and dyslipidemic populations of mixed cohorts, but its effectiveness in severe hypertriglyceridemia(SHTG) is unknown. This is a systematic review and meta-analysis to evaluate the efficacy of olezarsen in SHTG and the associated risk of pancreatitis. PubMed, Embase, and Cochrane databases were systematically searched for published trials comparing olezarsen vs placebo in SHTG patients up to December 03, 2025. We computed mean difference (MD) and risk ratio (RR) with 95% CI for continuous and binary endpoints, respectively, using a random-effects model. Significance level was set with P-value (< 0.05). From 228 database records, three randomized trials involving 1127 patients were included, with a 12-month follow-up. Of these, 748 patients (66.3%) received olezarsen. Olezarsen significantly reduced the mean percentage change from baseline of triglyceride (TG) levels, especially for the non–familial chylomicronemia syndrome(non-FCS) population (MD = − 59.95%; 95% CI − 76.00 to − 43.90; P = .001), of apolipoprotein C-III levels (MD = − 66.68%; 95% CI − 80.86 to − 52.69; P = .0006) at 6 months compared to placebo, albeit with significant heterogeneity. Significant reductions were also observed for other lipid parameters, specifically Non-high-density lipoprotein cholesterol (non-HDL-C) (MD = − 23.72%; 95% CI: − 27.35, − 20.09; P = .00001) and Remnant cholesterol(RC) (MD = − 55.30%;95% CI: − 62.05, -48.56; P = .00001) with an increase in LDL level. Olezarsen reduced the risk of acute pancreatitis (1.2% vs 8.7%; RR = 0.14; 95% CI: 0.07, 0.29; P = .00001) compared to placebo. No significant adverse events were observed between groups. Our analysis suggests olezarsen may be an effective therapeutic option in SHTG for reducing lipids and acute pancreatitis risk. However, its long-term safety and efficacy remain to be explored in future trials in this cohort.

TL;DR

In this systematic review and meta-analysis of three RCTs (1,127 patients with severe hypertriglyceridemia), olezarsen significantly lowered triglycerides, apolipoprotein C-III, non-HDL cholesterol, and remnant cholesterol versus placebo and reduced acute pancreatitis incidence. It did not increase overall adverse events, though LDL cholesterol rose and long-term outcomes remain uncertain.

Key findings

  • Olezarsen reduced the mean percentage change from baseline in triglycerides overall (MD = -55.01%; 95% CI: -61.97, -48.06; P = .00001; I² = 62%) and apolipoprotein C-III overall (MD = -65.66%; 95% CI: -70.75, -60.57; P = .00001; I² = 74%) compared with placebo.
  • Non-HDL cholesterol fell overall (MD = -23.92%; 95% CI: -26.93, -20.91; P = .00001; I² = 40%) and remnant cholesterol fell overall (MD = -55.30%; 95% CI: -62.05, -48.56; P = .00001; I² = 59%), while LDL cholesterol increased overall (MD = 53.25%; 95% CI: 46.85, 59.64; P = .00001; I² = 0%).
  • Acute pancreatitis occurred in 1.2% of olezarsen patients vs 8.7% of placebo patients (RR = 0.14; 95% CI: 0.07, 0.29; P = .00001; I² = 0%), corresponding to an 86% relative risk reduction.
  • Serious adverse events were lower with olezarsen (RR = 0.63; 95% CI: 0.41, 0.98; P = .04; I² = 24%); any adverse events did not differ significantly (RR = 0.97; 95% CI: 0.88, 1.07; P = .55; I² = 41%), nor did AST ≥3x ULN (RR = 2.04; 95% CI: 0.83, 4.98; P = .12; I² = 6%) or ALT ≥3x ULN (RR = 0.72; 95% CI: 0.04, 13.72; P = .83; I² = 74%).

Methods

  • Systematic review and meta-analysis registered in PROSPERO (CRD420251243520); PubMed, Embase, and Cochrane were searched from database inception to December 3, 2025, following PRISMA and Cochrane Handbook guidance.
  • Three RCTs were included (BALANCE, CORE-TIMI 72a, CORE-TIMI 72b), totaling 1,127 patients; 748 (66.3%) received olezarsen. Mean or median age ranged from 43.2 to 55 years, females accounted for 26%, and follow-up duration was 12 months.
  • Random-effects meta-analysis used mean difference for continuous endpoints and risk ratio for binary endpoints with 95% CIs; heterogeneity was assessed with Cochran’s Q, I², and tau-square; leave-one-out and FCS-exclusion sensitivity analyses and dose subgroup analyses were performed using RevMan web 9.17.0, with significance set at P < 0.05.

Limitations

  • Stated: only three RCTs were included, limiting statistical power for rare safety events; follow-up ranged from 6 to 12 months, leaving long-term lipid, pancreatitis, and cardiovascular mortality outcomes underexplored; substantial heterogeneity was driven by differences between FCS and broader hypertriglyceridemia populations; future trials are needed for population-specific outcomes; and the net long-term effect of the LDL cholesterol increase on atherosclerotic plaque burden remains unquantified.
  • Evident: the pooled analysis combines BALANCE (genetically confirmed FCS) with CORE-TIMI trials (multifactorial SHTG), so results may not apply uniformly across SHTG subtypes; publication bias was assessed only by funnel plots, and Egger’s test was not performed because fewer than 10 studies were included.

      The Discussion (p. 11) states that only patients with genetically confirmed familial chylomicronemia syndrome were enrolled in this trial.

      The Secondary End Points (p. 8) report fewer acute-pancreatitis episodes with pooled olezarsen than with placebo, supporting the direction of the claim. But the paper reports a rate ratio of 0.12 (95% CI, 0.02–0.66), not the cited percentages, RR of 0.14, confidence interval, P value, or I². It also says the secondary-end-point intervals were not adjusted for multiplicity and should not be interpreted as hypothesis tests, so the claim of a significant reduction overstates this trial's result.

  • The paper relies on this without support.

    The familial chylomicronemia syndrome and non-familial-chylomicronemia severe hypertriglyceridemia populations share a common downstream pathophysiology characterized by impaired clearance of triglyceride-rich lipoproteins mediated through the apolipoprotein C-III pathway.

    “However, both populations share a common downstream pathophysiology characterized by impaired clearance of TG-rich lipoproteins mediated through the apolipoprotein C-III pathway.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Conflicting non-HDL cholesterol reduction

    Minor

    The Discussion gives a reduction of 23.26%, but the Results report an overall reduction of 23.92%.

  • Apolipoprotein C-III sensitivity-analysis estimate is not centered in its confidence interval

    Minor

    The confidence-interval bounds have a midpoint of −61.71%, substantially different from the reported mean difference of −54.1%.

    Reported -54.1 · recomputed -61.71

  • Conflicting counts of full-text articles assessed

    Minor

    The Results state that 20 full-text articles were assessed, whereas the Figure 1 caption states that 30 were assessed.

  • 12-month LDL cholesterol estimate is not centered in its confidence interval

    Minor

    The bounds 43.74% and 62.57% have a midpoint of 53.155%, rather than the reported mean difference of 46.1%.

    Reported 46.1 · recomputed 53.155

  • TG sensitivity-analysis estimate is not centered in its confidence interval

    Minor

    For a mean difference, the reported confidence interval should be centered on its estimate under the stated methods. The bounds −55.32 and −42.53 have a midpoint of −48.925, not the reported −46.3.

    Reported -46.3 · recomputed -48.925

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-19.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-19.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
