Hypertriglyceridemia is a widely prevalent disorder of lipid metabolism that increases the risk of cardiovascular disease and pancreatitis, and it often remains difficult to control even with standard treatments. Olezarsen, an antisense oligonucleotide that targets apolipoprotein C-III (ApoC-III), offers a new and promising option for lowering triglyceride levels. A systematic search of PubMed, Scopus, Web of Science, and Cochrane was conducted through September 2025 to identify randomized controlled trials (RCTs) comparing olezarsen with placebo in adults with hypertriglyceridemia at high cardiovascular risk. Dichotomous outcomes were analysed as risk ratios (RRs) and continuous outcomes as percentage mean differences (MDs), both with 95% confidence intervals (CIs). Four RCTs (n = 1615 patients) were included. Olezarsen significantly reduced triglycerides (MD -47.71%, 95% CI -56.78 to -38.64, p < 0.0001), non-HDL-C (MD -22.11%, 95% CI -28.48 to -15.75, p < 0.0001), ApoC-III (MD -68.93%, 95% CI -77.54 to -60.31, p < 0.0001), VLDL-C (MD -48.52%, 95% CI -57.16 to -39.87, p < 0.0001), and ApoB (MD -10.67%, 95% CI -16.83 to -4.51, p = 0.0007), while increasing HDL-C (MD 35.13%, 95% CI -27.30 to -42.96, p < 0.0001). LDL-C showed no significant change. The risks of any or serious adverse events were comparable to placebo. Olezarsen was associated with fewer acute pancreatitis events (p = 0.035) but higher rates of liver enzyme elevations ≥ 3× ULN (p = 0.046). Olezarsen demonstrated consistent improvements in triglycerides and other atherogenic lipid parameters with an overall acceptable safety profile. These findings suggest that olezarsen may be a useful adjunct option for patients with persistent hypertriglyceridemia despite standard therapy. Further large-scale and long-term studies are needed to confirm its cardiovascular and safety outcomes. Show less

Obicetrapib, an oral cholesteryl ester transfer protein (CETP) inhibitor, has demonstrated potent LDL-C lowering in recent phase 2/3 trials. We evaluated Obicetrapib (1, 2.5, 5, and 10 mg) efficacy and safety in adults with dyslipidemia, with or without atherosclerotic cardiovascular disease (ASCVD) risk. We performed a meta-analysis of randomized controlled trials (RCTs) identified through PubMed, Cochrane, Scopus, and Web of Science up to June 2025. Dichotomous outcomes were analyzed as risk ratios (RRs) and continuous outcomes as mean differences (MDs), both with 95% confidence intervals (CIs). CRD420251107076. Six RCTs including 3399 patients were analysed. Compared with placebo, Obicetrapib significantly reduced LDL-C at 8-12 weeks (MD -27.66 mg/dL (-26.96%); 95% CI -33.62 to -21.70; p < 0.0001) and non-HDL-C (MD -35.41 mg/dL (-28.08%); 95% CI -39.42 to -31.39; p < 0.0001). It also increased HDL-C (MD 70.85 mg/dL (141.7%); 95% CI 62.56-79.15; p < 0.0001) and improved achievement of LDL-C targets: <55 mg/dL (RR 6.42; 95% CI 5.15-8.01), <70 mg/dL (RR 2.56; p < 0.0001), and < 100 mg/dL (RR 1.34; p < 0.0001). No significant differences were found in total adverse events (p = 0.41) or serious adverse events (p = 0.37). Obicetrapib provides substantial improvements in lipid parameters with a favourable short-term adverse events rate. These results support its role as a potential adjunctive lipid-lowering agent irrespective of ASCVD risk. Longer-term trials are warranted to confirm its durability, cardiovascular outcomes, and safety. Show less
