Early CRISPR trials show one-time gene edits can drastically lower cholesterol, but treatments remain experimental.
Scientists are testing gene-editing therapies using CRISPR to permanently lower high cholesterol, a major heart disease risk factor, in early-stage trials with a few dozen participants.
Two companies, including one backed by Eli Lilly, are targeting genes like ANGPTL3 and PCSK9 in the liver, with a single treatment showing up to 50% reductions in LDL cholesterol and triglycerides, lasting months to years.
While results are promising and could one day offer a one-time fix, the treatments remain experimental, with long-term safety, off-target effects, and risks like liver inflammation still unknown.
Experts stress that statins and lifestyle changes remain the standard of care, and widespread use is years away.
Los primeros ensayos de CRISPR muestran que las ediciones de genes de una sola vez pueden reducir drásticamente el colesterol, pero los tratamientos siguen siendo experimentales.
