Abstract
Objectives: To describe haemolytic disease outcomes, growth, neurodevelopment and health-related quality of life (HRQoL) through 24 months of life in infants exposed to nipocalimab in pregnancies at high risk of early-onset severe haemolytic disease of the fetus and newborn (EOS-HDFN).
Design: A multicentre, open-label, single-arm trial.
Setting: Centres with expertise in HDFN management.
Patients: Pregnant individuals with previous EOS-HDFN and maternal anti-D titres ≥32 or anti-K titres ≥4.
Interventions: Weekly nipocalimab (30 and/or 45 mg/kg) from 14 to 35 gestational weeks.
Main outcome measures: Infants' cord-blood alloantibody titres at birth, HDFN management, growth through 6 months, neurodevelopment (caregiver-reported Ages and Stages Questionnaire, third edition (ASQ-3)) and HRQoL assessments through 24 months of life.
Results: Of 13 pregnancies, 12 resulted in live births; one fetal loss occurred due to intrauterine transfusion (IUT) complications. A single simple transfusion was administered in one of seven infants delivered after a maternal nipocalimab course without IUTs, where cord blood alloantibody titres were <8. Multiple transfusions (one to seven simple transfusions/infant; one exchange transfusion) were administered to five infants delivered after early nipocalimab discontinuation and IUTs, with cord-blood alloantibody titres ranging from 512 to 32 768. No unusual growth patterns were observed through 6 months. No neurodevelopmental delays were identified through 24 months of life, with mean ASQ-3 domain scores within normal ranges. HRQoL outcomes were positive across physical, emotional, social and cognitive functioning.
Conclusions: Maternal nipocalimab in pregnancies at high risk of EOS-HDFN may reduce adverse neonatal outcomes correlating with low cord-blood alloantibody titres, without affecting growth through 6 months, neurodevelopment or HRQoL through 24 months of life.
期刊介绍:
Archives of Disease in Childhood is an international peer review journal that aims to keep paediatricians and others up to date with advances in the diagnosis and treatment of childhood diseases as well as advocacy issues such as child protection. It focuses on all aspects of child health and disease from the perinatal period (in the Fetal and Neonatal edition) through to adolescence. ADC includes original research reports, commentaries, reviews of clinical and policy issues, and evidence reports. Areas covered include: community child health, public health, epidemiology, acute paediatrics, advocacy, and ethics.
