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

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.

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.

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

Novo Nordisk's U.S.-listed shares are surging 9% Friday morning after the Danish drugmaker reported early stage results for its amycretin weight-loss drug.

Investors are upset at a lack of clarity over the results of Wegovy successor CagriSema after trials published in December.

Novo Nordisk on Wednesday said its new trial of its next-generation obesity drug candidate CagriSema will look at dose escalation and trial length to further show the drug's potential, after data in December disappointed the market.
