Novo Nordisk defended its next-generation obesity drug candidate CagriSema on Wednesday following late-stage trial data published in December that disappointed investors and wiped $125 billion from its market value.

In fact, Novo Nordisk recently reported positive results for one of its anti-obesity candidates that puts its current best-selling drug in this area, Wegovy, to shame. Let's look deeper into these results and what they could mean for investors.

The Danish maker of Ozempic and Wegovy reported a 25 percent increase in sales to $40.6 billion, but said it expected slower growth this year.

Novo Nordisk said on Wednesday it plan to file its experimental next-generation obesity drug CagriSema for regulatory approval during the first quarter of next year, slightly later than its previous expectation to file towards end-2025.

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

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