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

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

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

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

Novo Nordisk reported Q4 sales of $11.96 billion, beating estimates. The company plans a new phase 3 trial for CagriSema in 2025, with results expected in Q1.

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.
