Summary

This study tests a new drug called elinzanetant to see if it can reduce nighttime waking in menopausal women. About 110 women will take either the drug or a placebo for 12 weeks. Researchers will measure sleep quality using sleep tests and diaries.

What this could mean

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

Active substance
elinzanetant
What this could lead to
If it works, this could lead to a new non-hormonal treatment for sleep problems during menopause.
What could go wrong
This is a small, early-phase study with only 110 participants. The drug may not improve sleep more than placebo, and side effects are still being evaluated.
