Summary

This study tested a new medicine called NNC0662-0419 in 100 adults who are overweight or obese. The main goal was to check if the drug is safe and how the body handles it. Participants received either the drug or a placebo as a weekly injection under the skin. This is the first time this medicine has been given to people.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
NNC0662-0419
What this could lead to
If this early trial shows the drug is safe, it could lead to a new weekly injection for weight management.
What could go wrong
This is a very early Phase 1 study with only 100 people. Many drugs fail at this stage, and it will take years to know if it works for weight loss.
