New study investigates pregnancy risks for women on rare Fat-Disorder drug
NCT ID NCT05419037
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study looks at women with lipodystrophy, a condition causing abnormal fat tissue, who have been pregnant. Researchers want to see if taking the drug metreleptin during pregnancy affects the mother's or child's health. About 90 women and their children will share medical history and samples. The goal is to gather information, not to test a new treatment.
