Efficacy of Olezarsen in Severe Hypertriglyceridemia and Acute Pancreatitis Risk: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Open accessPublished version of a preprint
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 Fibrates section (page unavailable) reports triglyceride reductions of 16%, 26%, and 31% in cited trials, and the Omega-3 Fatty Acids section identifies triglyceride reduction as an effect. But the Acute Pancreatitis section discusses risk from elevated triglycerides, not whether fibrates or omega-3 fatty acids have been shown to prevent pancreatitis; the paper therefore does not support that part of the claim.

PremisecitationPrior systematic reviews and meta-analyses of olezarsen in hypertriglyceridemic or dyslipidemic cohorts were limited by small sample sizes, underpowered individual endpoints, lack of restriction to severe hypertriglyceridemia, and absence of systematic evaluation of pancreatitis as a clinical outcome.
“Prior systematic reviews and meta-analyses have reported the efficacy of olezarsen in hypertriglyceridemic or dyslipidemic cohorts; however, these studies were limited by small sample sizes, underpowered individual endpoints, lack of restriction to SHTG, and the absence of systematic evaluation of pancreatitis as a clinical outcome [10][11][12][13].”

In “Limitations and future research” (page unavailable), the review says its three included trials yielded a relatively small sample and restricted statistical power, and that it did not evaluate pancreatitis as a clinical outcome. Its Study selection criteria (page unavailable) do not restrict participants to severe hypertriglyceridemia. The paper does not specifically establish that individual endpoints were underpowered, so that part of the attributed claim goes beyond its findings. (LLM, conf=0.86)

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.
