Summary

This phase 2 trial tests whether an oral drug called MWN109 can help non-diabetic adults with overweight or obesity lose weight. About 255 participants will take either one of four doses of MWN109 or a placebo daily for 20 weeks. Researchers will measure changes in body weight and waist size to see if the drug is effective and safe.

What this could mean

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

Active substance
MWN109 tablet
What this could lead to
If it works, MWN109 could offer a new oral option for weight loss in people who are overweight or obese but not diabetic.
What could go wrong
This is an early phase 2 trial with a modest number of participants, so results may not hold up in larger studies. The drug may cause side effects or fail to produce meaningful weight loss.
