Une étude sur le nipocalimab dans les grossesses à risque de maladie hémolytique sévère du fœtus et du nouveau-né (HDFN) (AZALEA)
Une étude de phase 3 randomisée, contrôlée par placebo, en double aveugle et multicentrique pour évaluer l'efficacité et l'innocuité du nipocalimab dans les grossesses à risque de maladie hémolytique sévère du fœtus et du nouveau-né (HDFN)
The purpose of this study is to assess the effectiveness of nipocalimab when compared to placebo in decreasing the risk of fetal anemia (a condition in which a baby's red blood cell volume falls below normal levels while the baby is developing in the womb) with live neonates in pregnant participants at risk for severe hemolytic disease of the fetus and newborn.
