Brief Summary:
The purpose of this study is to evaluate the safety in mother and neonate/infant of M281 administered to pregnant women who are at high risk for Early Onset Severe Hemolytic Disease of the Fetus and Newborn (EOS-HDFN). The effectiveness of the investigational drug M281 will be measured by looking at the percentage of participants with live birth at or after gestational age (GA) 32 weeks and without a need for an intrauterine transfusion (IUT) throughout their entire pregnancy.

Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AEs) [ Time Frame: From signing of informed consent up to approximately 24 weeks post-delivery for mothers; up to approximately 96 weeks post birth for neonates ]
  2. Number of Participants With Live Birth at or After Gestational Age (GA) Week 32 and no Intrauterine Transfusion (IUT) Throughout Their Entire Pregnancy [ Time Frame: Up to approximately GA Week 37 ]

Secondary Outcome Measures :
  1. Global Clinical Outcome (GCO) Rank Score (GCO Rank) [ Time Frame: Up to approximately GA Week 37; up to approximately 12 weeks post birth ]
  2. Number of Participants With GCO Clinically Meaningful Classification (GCO Class) [ Time Frame: Up to approximately GA Week 37; up to approximately 12 weeks post birth ]
  3. Number of Participants With live Birth [ Time Frame: Up to approximately GA Week 37 ]
  4. Number of Participants at GA Week 24 Without an IUT [ Time Frame: GA Week 24 ]
  5. Gestational age at First IUT [ Time Frame: Up to approximately GA Week 37 ]
  6. Number of IUTs Required [ Time Frame: Up to approximately GA Week 37 ]
  7. Gestational age at Delivery [ Time Frame: Up to approximately GA Week 37 ]
  8. Number of Participants With Fetal Hydrops [ Time Frame: Up to approximately 24 weeks post birth ]
    Fetal hydrops is severe edema in the skin and serous cavities of the neonate.

  9. Number of Neonates Requiring Phototherapy [ Time Frame: Up to approximately 24 weeks post birth ]
  10. Number of Neonates Requiring Exchange transfusions [ Time Frame: Up to approximately 24 weeks post birth ]
  11. Number of Days of Postnatal Phototherapy Required by Neonate [ Time Frame: Up to approximately 24 weeks post birth ]
  12. Number of Neonates Requiring Simple Transfusions in the First 12 weeks of Life [ Time Frame: Up to 12 weeks post birth ]
  13. Number of Simple Transfusions Required by Neonate in the First 12 weeks of Life [ Time Frame: Up to 12 weeks post birth ]
  14. Percentage of Maternal Fc Receptor (FcRn) Receptor Occupancy (RO) [ Time Frame: GA Week 14 to approximately GA Week 36 ]
  15. Maternal Levels of Total Immunoglobulin G (IgG) [ Time Frame: GA Week 14 to approximately GA Week 36 ]
  16. Maternal Levels of Alloantibodies [ Time Frame: GA Week 14 to approximately GA Week 36 ]
  17. Mean Concentration of M281 in Maternal Participants [ Time Frame: GA Week 14 to approximately GA Week 36 ]

Criteria
Pregnant female participants must be ≥18 years of age with an estimated gestational age of 8 to 13 weeks at enrollment; a previous pregnancy with a gestation that included at least one condition [severe fetal anemia, fetal hydrops (ascites), or stillbirth with fetal or placental pathology indicative of Hemolytic Disease of the Fetus and Newborn] at ≤24 weeks gestation; not currently pregnant with multiples (twins or more), up to date on required immunizations; and no other clinically relevant abnormalities currently or in their history that the Investigator would deem them ineligible to participate.
