Carbetocin nasal spray did not reduce overeating in Prader-Willi syndrome in a phase 3 trial

Peer-reviewed publication

A study published in a journal and reviewed by independent scientists. Even so, a single study is not conclusive; it needs to be replicated.

In 175 people with Prader-Willi syndrome, carbetocin given as a nasal spray was compared with placebo. Treatment lasted 12 weeks. Excessive hunger decreased to a similar degree in both groups. The drug was not found to be better than placebo. The most common side effects were headache and fever.

What does it mean for patients and families?

This drug showed no benefit in this study. Diet and close supervision remain the basis for managing excessive hunger.
