Primary | Latency (in Days) From Enrollment to Delivery | The difference in mean number of days (latency) from enrollment in the study (or hospital admission for controls) to delivery between participant receiving eculizumab compared to historical controls.
For treatment-arm participants latency is determined from enrollment to delivery. For historical controls latency is determined from hospital admission (or initial diagnosis for controls hospitalized for other indication) for preeclampsia until delivery. Subjects and historical controls all defined as women with preeclampsia between 23-30 weeks gestation. |
24 months | |
Secondary | Composite Adverse Maternal Outcomes | The difference in the composite number of adverse maternal outcomes between subjects receiving eculizumab compared to historical controls
•Adverse maternal outcomes directly attributed to preeclampsia defined as the following: syndrome of hemolysis, elevated liver enzyme, and low platelet count (HELLP), eclampsia, placental abruption, stroke, venous thrombosis or pulmonary embolism, pulmonary edema, posterior reversible encephalopathy syndrome, postpartum hemorrhage (>1000 cc), blood transfusion, admission to the intensive care unit, acute kidney injury, acute tubular necrosis, dialysis, or death |
24 months | |
Secondary | Composite Adverse Neonatal Outcomes | The difference in the composite number of adverse neonatal outcomes between subjects receiving eculizumab compared to historical controls.
•Adverse neonatal outcomes directly attributable to preeclampsia or indirectly attributable due to preterm delivery due to preeclampsia defined as the following: Respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, seizure, hypoxic-ischemic encephalopathy, metabolic acidosis, infection, sepsis, previously unrecognized major malformation detected at birth, patent ductus arteriosus requiring indomethacin, or death. |
