Eligibility
Key inclusion criteria
* Approximately 15 eligible participants and their offspring will be enrolled
* Each participant must meet all of the following criteria to be enrolled in the study:
* Female and greater than or equal to (>=)18 years of age
* Pregnant to an estimated gestational age of between 8 up to 14 weeks
* A previous pregnancy with a gestation that included at least one of the following prior to week 24 gestation:
* Severe fetal anemia, defined as hemoglobin less than or equal to (<=) 0.55 multiples of the median (MOM) for gestational age
* Fetal hydrops with peak systolic velocity MOM >=1.5
* Stillbirth with fetal or placental pathology indicative of hemolytic disease of the fetus and newborn (HDFN)
* Maternal alloantibody titers for anti-D of >=32, or anti-Kell titers >=4
* Free fetal deoxyribonucleic acid consistent with an antigen-positive fetus (blood sample taken from mother)
* Maternal evidence for Immunity to measles mumps, rubella, and varicella, as documented by serologies performed during Screening. If initial serologies are borderline or negative, they may be repeated at a second lab. Alternatively, vaccination records can be used to support evidence of immunity.
* Screening immunoglobulin G and albumin levels within the laboratory normal range for gestational age of pregnancy
* Willing to receive standard of care with intrauterine transfusion if clinically indicated
* Agree to receive recommended vaccinations per local standard of care for both mother and child throughout the course of the study
* It is recommended that patients are up-to-date on age-appropriate vaccinations prior to screening as per routine local medical guidelines. For study patients who received locally-approved (and including emergency use-authorized) Coronavirus Disease 2019 (COVID-19) vaccines recently prior to study entry, follow applicable local vaccine labelling, guidelines, and standard of care for pregnant women receiving immune-targeted therapy when determining an appropriate interval between vaccination and study enrollment

Key exclusion criteria
* Currently pregnant with multiples (twins or more)
* Pre-eclampsia In current pregnancy or history of pre-eclampsia in a previous pregnancy
* Gestational hypertension in the current pregnancy
* Current unstable hypertension
* History of severe or recurrent pyelonephritis, 4 or more lower urinary tract infections in the past year or in a previous pregnancy
* History of genital herpes infection
* Active Infection at Screening or Baseline with Coxsackie, syphilis, cytomegalovirus, toxoplasmosis or herpes simplex 1 or 2, as evidenced by clinical signs and symptoms (evidence for prior Infection or exposure, but without clinical signs and symptoms of active infection is acceptable)
* Active infection with tuberculosis as evidenced by positive QuantiFERON-tuberculosis testing
* Requires treatment with corticosteroids or immunosuppression for disorders unrelated to the pregnancy (use of low-potency topical corticosteroids or intra-articular corticosteroids is permitted)
* Has received or is expected to receive any live virus or bacterial vaccine within 12 weeks prior to screening or has a known need to receive a live vaccine while receiving nipocalimab, or within 12 weeks after the last administration of nipocalimab in the study or has received Bacille Calmett-Guérin (BCG) vaccine within 1 year prior to the first administration of nipocalimab
* Currently receiving an antibody-based drug or an Fc-fusion protein drug
* Received plasmapheresis and/or intravenous immunoglobulin during the current pregnancy for treatment of HDFN
* COVID-19 infection: during the 6 weeks prior to baseline (regardless of vaccination status), have had any of: a) confirmed severe acute respiratory syndrome coronavirus(-2) (SARS-CoV-2) (COVID-19) infection (test positive), or; b) suspected SARS-CoV-2 infection (clinical features without documented test results), or; c) close contact with a person with known or suspected SARS-CoV-2 infection. Exception: may be included with a documented negative result for a validated SARSCoV-2 test: obtained at least 2 weeks after conditions a), b), c) above (timed from resolution of key clinical features if present, example fever, cough, dyspnea) and; with absence of all conditions a), b), c) above during the period between the negative test result and the baseline study visit
