介入・治療 |
|---|---|
|
実験的:Arm 1: Nipocalimab
Maternal participants with alloantibodies against HPA-1a and/or HPA-5b will be randomized to receive nipocalimab starting at gestational age (GA) week 13 to 18 until before delivery. |
Nipocalimab will be administered intravenously.

|
実験的:Arm 2: Intravenous Immunoglobins (IVIG)
Maternal participants with alloantibodies against HPA-1a and/or HPA-5b will be randomized to receive IVIG from GA week 12 for high-risk pregnancies or GA week 20 for standard-risk pregnancies. Additionally, prednisone will be added per study protocol. Participants will be gradually tapered off prednisone after delivery as per investigator judgement or maternal participant tolerance. |
IVIG will be administered intravenously. Prednisone will be administered orally. |

Bayley Scales Assessment for Infant Development
時間枠:At Week 52 and Week 104
|
The Bayley Scales of infant development is considered the standard assessment of early child development and includes cognition, language, motor skills, social emotional, and adaptive behavior will be reported. The Bayley Scales are reference standards that measure infant and toddler development in five areas: cognition, language, motor skills, social-emotional and adaptive behavior. The cognition, language and motor skills scales are directly administered to the infant, while social-emotional, and adaptive behavior scales are caregiver questionnaires. The scores are standardized using norm reference samples with representative demographics and age adjusted for prematurity. Higher scores in the Bayley Scales indicate better outcomes. |
At Week 52 and Week 104
|
|

時間枠:Up to Week 4
|
Incidence of antibodies to nipocalimab including neutralizing antibodies in maternal serum during pregnancy and postpartum will be reported. |
