Novo's Wegovy shows heart benefit alongside weight loss in trial

Wegovy maker Novo Nordisk said on Tuesday (Aug 8) a large study had shown the highly effective obesity treatment also had a clear cardiovascular benefit, boosting the Danish company's hopes of moving beyond its image as a lifestyle drug.

The increasingly popular Wegovy has transformed the weight-loss market since its U.S. launch in June 2021, capturing the attention of patients, investors and celebrities worldwide.

Novo's news lifted shares in Europe's second-most valuable listed company after LVMH by more than 17 per cent to record highs. They have now surged almost 165 per cent over the past two years.

The results of the late-stage trial may help persuade insurers in the U.S. and cost-conscious health authorities in Europe to cover the cost of Wegovy, which is $1,300 a month in the United States, for a wider range of patients.

U.S. law classifies weight-loss treatments as lifestyle drugs and bars the Medicare health plan for older Americans from covering them and experts said the new data could lead the U.S. government to reassess that.

Novo said the eagerly-awaited study results, which have not been peer reviewed, showed that patients on Wegovy had a 20 per  cent lower incidence of heart attack, stroke or death from heart disease compared to those on a placebo. That is significantly better than the 15-17 per cent expected by investors and analysts.

The study, called SELECT, involved 17,500 overweight or obese people with a history of heart disease aged 45 years or older with no prior history of diabetes. It started almost five years ago to test if the weekly injection has medical benefits.

The results will likely stir debate about whether the long-term medical benefits are enough to reduce the overall burden on healthcare systems and the cost of treating heart disease in overweight and obese people.

"I suspect that medical claims savings from this are years away," said Dr. Jeff Levin-Scherz, a consultant at Willis Towers Watson, which advises employers on benefits.

He said the drugs at best may prove to be cost effective in terms of improving patients' lives, rather than lowering their total cost of care.

Large U.S. companies who manage their employees' healthcare benefits and traditionally covered weight-loss treatments have scaled back due to spiralling costs.

Still, the landmark trial data shows Wegovy has "the potential to change how obesity is regarded and treated", said Martin Holst Lange, executive vice president for development at Novo, in the statement.

Novo said it expects to file for regulatory approvals of a label indication expansion for the weekly injection in the U.S. and European Union this year.

The detailed results from the trial will be presented at a scientific conference later in 2023. Analysts will be seeking more detail with Novo's second-quarter results on Thursday.

Cause a stir

More than half a dozen companies, from Pfizer and Amgen, are working on weight-loss therapies similar to Wegovy, hoping for a slice of a market estimated to be worth as much as $100 billion by the end of the decade.

The weekly injection makes patients feel full for longer and leads to an average weight loss of around 15 per cent when combined with changes to diet and exercise.

It belongs to a class of drugs known as GLP-1 agonists, originally developed to treat type 2 diabetes. Eli Lilly and Co is expected to receive a U.S. weight-loss approval for its similar drug, Mounjaro, later this year.

Over 650 million adults worldwide are obese, more than three times as many as in 1975, and roughly another 1.3 billion are overweight, exacerbating conditions such as heart disease and diabetes, the World Health Organization says.
