Ozempic and Wegovy maker Novo Nordisk quieted Wall Street's concerns with its fourth-quarter results and 2025 outlook.

New GLP-1RA weight loss drugs like Like Ozempic and Wegovy have become extremely popular in recent months but researchers continue to analyze their health

We talk Ozempic, Wegovy and Mounjaro. A number of studies have shown the amazing weight loss potential of a new group of drugs, known to many by their brand names as Ozempic (which is for diabetes), Wegovy and Mounjaro. But how do these new drugs work? How were they discovered and who can use them?

In the first half of 2025, Ozempic developer Novo Nordisk in Bagsværd, Denmark, expects results from a second phase III trial of its experimental drug CagriSema — a combination of semaglutide and a medicine called cagrilintide. People on CagriSema lost about 23% of their body weight in a 68-week study, outperforming both drugs when taken alone.

The use of blockbuster weight loss drugs has surged among young women, for whom the treatments can often be "liberating."

The drugmaker expects the regulator to remove Wegovy and Ozempic from its shortage list, blocking other companies from legally selling cheap knockoff versions.
