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.

CagriSema, which underperformed expectations in its first Phase 3 test, will be studied at different doses and for longer duration in the new trial.

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.

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

Novo Nordisk's CagriSema trial raised concerns as patients reported weight loss but significant side effects. Investors question trial protocols and transparency as Novo plans a new study.

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.
