US FDA approves Novo Nordisk drug Wegovy for use in lowering heart attack risks

(Reuters) -The U.S. Food and Drug Administration approved Novo Nordisk's weight-loss drug Wegovy on Friday for lowering the risk of stroke and heart attack in overweight or obese adults who are not diabetic.

Novo's widely used diabetes drug Ozempic and weight-loss drug Wegovy, both chemically known as semaglutide, belong to a class of drugs called GLP-1 agonists. Originally developed for type 2 diabetes, they also reduce food cravings and cause the stomach to empty more slowly.

Patients who are obese or overweight are at "a higher risk of cardiovascular death, heart attack and stroke. Providing a treatment option that is proven to lower this cardiovascular risk is a major advance for public health," said John Sharretts, FDA's director of the Division of Diabetes, Lipid Disorders, and Obesity.

Millions of people already take Novo's GLP-1 drugs, but the FDA's stamp of approval for the cardiovascular benefits is likely to open their use to more patients.

Healthcare professionals should monitor patients for kidney disease, diabetic retinopathy and depression or suicidal behaviors or thoughts, the FDA said.

The Danish drugmaker published the full data in November from a large clinical trial that showed the obesity drug reduced the risk of non-fatal heart attack by 28%, non-fatal stroke by 7% and heart-related death by 15%, compared with a placebo, in patients with pre-existing heart conditions.

In the 17,604-patient trial with a mean duration of 33 months, the difference in heart protective benefits began to appear almost immediately after starting treatment in those who received Wegovy compared with the placebo group, researchers said, suggesting the positive impact was due to more than weight loss.

The FDA's approval of the new cardiovascular indications could give employers and insurers more reason to cover the drug despite its high cost.

Health regulators can expand approved uses of medicines if new data shows them to be effective in other therapeutic areas after initial approval.

Novo's application for allowing use of Wegovy to reduce the risk of strokes and heart attacks is currently under review by the European Union's drug regulator. It expects a decision this year.

U.S.-listed shares of Novo Nordisk were down 2% in afternoon trading.

Wegovy, which has been shown to help patients lose an average of 15% of their weight after 68 weeks of treatment, was first approved by the FDA to treat obesity in June 2021.

Some leading U.S. obesity specialists have said they expected Eli Lilly's rival weight-loss drug Zepbound would produce the same or similar heart benefits as Wegovy because both belonged to the same class of medicine.

Lilly expects to publish data from a late-stage trial testing Zepbound as a treatment for heart failure later this year.
