In a new [article](https://www.nejm.org/doi/full/10.1056/NEJMc2609825?query=featured%5Fhome) published in the _New England Journal of Medicine_, researchers report that a gene-editing therapy helped people with increased levels of cholesterol and triglycerides maintain lower levels of these lipids for at least a year. The findings build on [earlier results](https://time.com/7332139/gene-therapy-treatment-lower-cholesterol/) of the therapy, reported last November. The gene-editing treatment, developed by the biotech company CRISPR Therapeutics, uses CRISPR technology to precisely edit a gene involved in cholesterol regulation. The gene, called ANGPTL3, makes an enzyme that blocks the breakdown of bad cholesterol (LDL) and triglycerides. But scientists discovered a long-lived population in Italy in which people born with a mutation in ANGPTL3—rendering it defective—had low levels of LDL and triglycerides and very little heart disease. The CRISPR therapy mimics this naturally occurring mutation; people who have received it now have this mutation in their ANGPTL3, which means they can now break down cholesterol and triglycerides properly. In the small study, 15 people with severe forms of high cholesterol and triglycerides showed drops in the two lipids of up to 50%, which the latest results show lasted for at least a year. “From an efficacy standpoint, it’s a pretty big win,” says [Samarth Kulkarni](https://time.com/collections/time100-health-2025/7279635/samarth-kulkarni/), CEO of CRISPR Therapeutics. The fact that the people in the study were able to maintain lower levels of LDL and triglycerides for up to a year means that CRISPR was able to edit enough cells in the liver, where much of the body’s cholesterol and triglycerides are produced, to give patients the benefit of having lower levels of the lipids. It also shows that these edited cells continue to produce new generations of cells that carry the CRISPR edit in AGNPTL3\. People who received the highest dose of the CRISPR therapy saw levels of the ANGPTL3 enzyme drop by nearly 80%, which contributed to a drop in LDL and triglycerides of about 50%. “This is a really big step for CRISPR to show the durability of the result,” says Dr. Luke Laffin, co-director of the Center for Blood Pressure Disorders at the Cleveland Clinic and lead author of the study. The CRISPR therapy did not cause significant side effects—and researchers did not expect it to, since people born with the defective ANGPTL3 gene don’t seem to have serious diseases either. That means the one-time therapy could potentially replace the current treatment for high LDL and triglycerides: daily statin pills. While effective, many people don’t take the pills on a daily basis for years, which lowers their effectiveness. “We could look at a situation further down the line where we are able to give people a choice,” says Laffin. In the future, if someone has a serious family history of heart disease or high cholesterol, for example, “this therapy may be an option for them where we could treat them now, edit their \[liver cells\], and they can continue to have a genetic defect that we know is safe and will control their cholesterol.” Kulkarni says the company has already begun the next phase of studies and anticipates additional results by the end of this year. That study will continue to focus on people with severe cases of high cholesterol and triglycerides, which affects about two to three million people in the U.S. If that study and further late-stage studies of the CRISPR therapy continue to show positive results, the company might consider conducting studies in people with more average elevations in their lipids. “The biggest promise of gene-editing in cardiovascular medicine is the notion of a one-time treatment that would be all you need,” he says. “Once you reduce levels of ANGPTL3, it remains durably reduced—presumably for life, but at least for one year. It’s very exciting.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/article/2026/08/28/one-time-treatment-high-cholesterol-crispr-results/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/article/2026/08/28/one-time-treatment-high-cholesterol-crispr-results/"},"headline":"An Experimental One-Time Treatment for High Cholesterol Shows Promising Results","datePublished":"2026-08-28T18:54:11.000Z","dateModified":"2026-08-29T00:17:50.000Z","description":"An experimental CRISPR-based gene-editing therapy could be a one-and-done treatment for high cholesterol and high triglycerides, a study suggests.","url":"https://time.com/article/2026/08/28/one-time-treatment-high-cholesterol-crispr-results/","keywords":["cholesterol","Heart Disease"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3d9d82b0cf494a16/6a9094d9a81f2ee66803c947/GettyImages-1290651276.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3d9d82b0cf494a16/6a9094d9a81f2ee66803c947/GettyImages-1290651276.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"GettyImages-1290651276.jpg","caption":"","creditText":"Eugene Mymrin—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/cholesterol/","name":"cholesterol"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/article/2026/08/28/one-time-treatment-high-cholesterol-crispr-results/","name":"An Experimental One-Time Treatment for High Cholesterol Shows Promising Results"}}]}] ```
