Frequently asked questions about NNC0581-0001

What is NNC0581-0001?

NNC0581-0001 is an investigational small molecule developed by Novo Nordisk A/S for hepatic steatosis, a condition involving fat accumulation in the liver. It is in Phase 1 clinical development and has been studied in two trials totaling 96 participants. It is not yet approved for any indication.

What is NNC0581-0001 used for in hepatic steatosis?

NNC0581-0001 is being developed to potentially treat hepatic steatosis, also known as fatty liver. The clinical program has enrolled healthy volunteers and participants with hepatic steatosis in the United Kingdom. Because it remains in Phase 1 testing, its safety and activity in patients are still being evaluated.

Who is developing NNC0581-0001?

NNC0581-0001 is being developed by Novo Nordisk A/S, which trades under the ticker NVO. The company is running the Phase 1 program for this small molecule candidate in hepatic steatosis, with trials conducted in the United Kingdom.

What phase is NNC0581-0001 in?

NNC0581-0001 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA or any other regulator. Two Phase 1 trials have been conducted, one completed and one currently recruiting, with a combined enrollment of 96 participants.

What clinical trials is NNC0581-0001 in?

NNC0581-0001 has been studied in two Phase 1 trials. NCT05599945 was a completed first human dose trial in healthy volunteers and hepatic steatosis. NCT06891365 is an ongoing multiple dose study in healthy volunteers and hepatic steatosis that is currently recruiting in the United Kingdom.

How is NNC0581-0001 studied in its clinical trials?

The NNC0581-0001 trials are randomized, double-blind, and controlled, with 48 participants enrolled in each study. NCT05599945, the completed first human dose trial, enrolled healthy volunteers. NCT06891365, the recruiting multiple dose study, includes healthy volunteers and participants with hepatic steatosis in the United Kingdom.
