Summary

This study tests whether giving melatonin to pregnant women with a severe form of fetal growth restriction can help their babies. The trial will involve 240 women who will take either melatonin or a placebo nightly. Researchers will track baby growth, pregnancy length, and newborn health to see if melatonin reduces serious complications.

What this could mean

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

Active substance: Melatonin
What this could lead to: If it works, this could point toward a simple, safe treatment to help babies with severe growth restriction grow better and have fewer complications.
What could go wrong: This is an early phase 1 trial, so it is primarily testing safety. The dose and timing may not be optimal, and the results may not apply to all cases of fetal growth restriction.
