Promising preeclampsia drug trial halted early – what happened?
NCT ID NCT03008616
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an experimental drug called AMAG-423 (Digoxin Immune Fab) in pregnant women with severe preeclampsia, a dangerous condition of high blood pressure during pregnancy. The goal was to see if the drug could reduce serious health problems in babies, such as bleeding in the brain or bowel issues, and improve kidney function in mothers. The trial was stopped early after enrolling 58 participants, so results are limited.
