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.

Novo Nordisk is under pressure from investors for more information about its next-generation obesity drug candidate CagriSema amid a lack of clarity over trial results that hammered its shares in December.

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.

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

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.

Novo Nordisk shares jump close to 14% on promising trial results for amycretin, a once-weekly obesity drug, signaling fierce competition in the weight-loss market.
