Summary

This early-phase study tests whether adding melatonin to standard cooling therapy can improve brain outcomes in newborns with hypoxic-ischemic encephalopathy (HIE), a condition caused by oxygen loss at birth. About 70 full-term infants will receive different doses of melatonin to find the safest and most effective amount. The goal is to reduce brain damage and improve development as the child grows.
