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.

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

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.

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

A Novo Nordisk A/S investor says the pharmaceutical company’s failure to disclose how it tested experimental obesity shot CagriSema caused economic damage after patients lost less weight using the drug than previously predicted.

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’s newest GLP-1, CagriSema, is the first big test of Novo Nordisk’s future as the leader in the obesity treatment market. The drug is more potent than Ozempic and Wegovy, expanding treatment to heavier patients while perhaps reducing treatment times for other individuals.
