WASHINGTON (AP) — Scientists are testing an entirely new way to fight heart disease: a gene-editing treatment that might offer a one-time fix for high cholesterol.

It’s very early stage research, tried in only a few dozen people so far. But gene-editing approaches being developed by two companies show hints that switching off certain genes could dramatically lower artery-clogging cholesterol, raising hopes of one day being able to prevent heart attacks without having to take pills.

“People want a fix, not a bandage,” said Dr. Luke Laffin, a preventive cardiologist at the Cleveland Clinic. After co-authoring a promising study published in the New England Journal of Medicine, he said he was flooded with queries about how to participate in the next clinical trial.
