Key result
Gene-based therapies enable sustained atherogenic lipid reductions through infrequent dosing.
Why the study?
Conventional lipid-lowering therapies are often limited by lifelong treatment requirements, suboptimal adherence, and inadequate achievement of lipid targets, particularly in patients with inherited disorders such as familial hypercholesterolemia.
Gene-based therapies targeting lipid metabolism offer a paradigm shift in preventive cardiology by enabling durable, precision-based reductions in atherogenic lipids with infrequent dosing.

“It is still early days but this is an extremely exciting milestone. These findings show the technology works, is safe and helps lower cholesterol to levels similar to medicines we currently have. The therapy has the potential to provide a ‘one and done’ approach to a very common condition, which would be transformative in preventing heart attacks and strokes over the long term.”
“People want a fix, not a bandage.”
“There are major safety questions to be answered. CRISPR-based therapies for any disease haven't been used enough to know long-term safety — and the particles carrying the gene-editing tool can irritate or inflame the liver. Another unknown is whether gene-editing hits only the intended target.”
Should not yet alter lipid management; leaves open the role of gene-based therapies pending randomized safety and efficacy data.
Dyslipidemia is a major driver of atherosclerotic cardiovascular disease, with elevated low-density lipoprotein cholesterol (LDL-C) and triglycerides playing key roles in disease progression. Although conventional lipid-lowering therapies such as statins, ezetimibe, bempedoic acid, and proprotein convertase subtilisin/kexin type 9 inhibitors are effective, their impact is often limited by lifelong treatment requirements, suboptimal adherence, and inadequate achievement of lipid targets, particularly in patients with inherited disorders such as familial hypercholesterolemia. Recent advances in gene-based therapies have introduced a paradigm shift by targeting lipid metabolism at its genetic and molecular basis. Techniques including CRISPR-Cas9 gene editing, small interfering RNA, and antisense oligonucleotides enable precise modulation of key genes such as PCSK9, ANGPTL3, APOC3, and LPA, leading to sustained reductions in atherogenic lipids. These therapies act upstream at the level of gene expression or mRNA, offering improved specificity, longer duration of action, and the potential for infrequent or single-dose administration. Clinical and translational studies demonstrate significant lipid-lowering efficacy across multiple pathways, including LDL-C, triglycerides, and lipoprotein(a), addressing previously unmet therapeutic needs. Despite their promise, important challenges remain, including long-term safety concerns, off-target effects, cost, ethical considerations, and regulatory complexities. Emerging strategies such as combination gene targeting and personalized genomic therapy further expand therapeutic potential while supporting a transition toward preventive cardiology. Overall, gene-based therapies represent a transformative approach in lipid management, with the potential to overcome the limitations of conventional treatments and enable durable, precision-based cardiovascular risk reduction.

Prabhash C Manoria (2026) conducted a review in Dyslipidemia and atherosclerotic cardiovascular disease. Gene-based therapies (CRISPR-Cas9, siRNA, and ASOs) vs. Conventional lipid-lowering therapies was evaluated. Gene-based therapies, including CRISPR-Cas9, siRNA, and ASOs, offer a transformative approach to lipid management by enabling sustained reductions in atherogenic lipids through infrequent dosing.
