Frequently asked questions about NNC0581-0001

What is NNC0581-0001 used for?

NNC0581-0001 is an investigational small molecule being developed by Novo Nordisk for the potential treatment of liver diseases, including hepatic steatosis. It is currently in Phase 1 clinical trials studying healthy volunteers, with the goal of evaluating its safety and tolerability as a first step toward treating liver conditions.

Who makes NNC0581-0001?

NNC0581-0001 is being developed by Novo Nordisk A/S, a pharmaceutical company listed on the stock exchange under the ticker symbol NVO. The company is conducting Phase 1 clinical trials to evaluate this investigational small molecule for potential treatment of liver diseases.

What phase is NNC0581-0001 in?

NNC0581-0001 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still being studied in clinical trials. Two Phase 1 trials have been conducted or are ongoing, with one completed and one currently recruiting participants.

What clinical trials is NNC0581-0001 in?

NNC0581-0001 has been studied in two Phase 1 clinical trials. The first, NCT05599945, was a completed first human dose trial in healthy volunteers and participants with hepatic steatosis in the United Kingdom. The second, NCT06891365, is a recruiting multiple dose study also in the UK, with a total of 96 participants across both trials.

How does NNC0581-0001 work?

NNC0581-0001 is a small molecule being developed for liver diseases, but its specific molecular target has not been disclosed. The clinical trials are designed to evaluate its safety, tolerability, and pharmacokinetics in healthy volunteers, with the goal of understanding how it may potentially treat conditions like hepatic steatosis.
