Usefulness of Extracorporeal Removal of sFLT-1 in Women With Very Early Severe Preeclampsia
A Phase 2 study testing Apheresis for extracorporal removal of sFlt-1 in people with Preeclampsia, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.
Trial summary
Introduction Preeclampsia is a multifactorial disease that is responsible of important adverse maternal and perinatal outcomes. Recently, it has been suggested that soluble fms-like tyrosine kinase 1, s-Flt1, induces preeclampsia-like phenotype in experimental models and circulates at elevated levels in human… Read more about this study

About this study
Official title: Usefulness of Extracorporeal Removal of sFlt-1 in Women With Severe Preeclampsia at Less Than 26 Weeks' Gestation
Introduction Preeclampsia is a multifactorial disease that is responsible of important adverse maternal and perinatal outcomes. Recently, it has been suggested that soluble fms-like tyrosine kinase 1, s-Flt1, induces preeclampsia-like phenotype in experimental models and circulates at elevated levels in human preeclampsia.
The aim of our study is to see whether removal of s-Flt1 may improve perinatal death in women with very early severe preeclampsia at less than 26 weeks' gestation Patients and methods Phase II trial. Women with singleton pregnancy having severe preeclampsia at 23-256/7 weeks' gestation. Women under 18 years, with multiples, or severe fetal growth restriction (less than 5th centile), or abnormal fetal heart rate, or maternal complications (abruption, eclampsia, HELLP syndrome, pulmonary edema, DIC, liver hematoma) are excluded from the study. After blood pressure and maternal stabilization, women are approached for information and if they agree, to sign the trial consent.

Women have twice weekly extracorporeal removal of s-Flt1 until 34 weeks' gestation.
Primary endpoint or success of the procedure: baby alive or alive at 6 months if hospitalized Statistical procedure Simon minimax plan; P0: 60%, P1, 90%, alpha error: 5%, beta power; 90%. First step: number 8 patients. If success equal or less than 5, the study is stopped.
Second step: if success of 6 or more, the study is continued for 9 more patients.
Overall, a maximum of 17 patients will be included. The final success of extracorporeal removal of s-Flt1 will be considered if 14 or more babies will be alive or alive at 6 months if hospitalized.

After blood pressure and maternal stabilization, women are approached for information and if they agree, to sign the trial consent.
They will then be admitted to the department of Renal intensive care of Tenon Hospital. LDL apheresis will be performed twice weekly, during 90 minutes per session, using the DALI 750 Kit and the ART device (Fresenius). sFlt1 will be measured in peripheral blood before and after each session. The treatment will end when delivery is indicated (whether because of threatening complications or because a viable term of pregnancy is achieved).
Primary endpoint or success of the procedure: a live born baby alive at 6 month after birth.
Secondary endpoints: days of pregnancy prolongation, blood pressure during apheresis, fetal heart rate monitoring after apheresis, maternal levels of s-Flt1, PlGF, and s-endoglin.
Maternal adverse outcomes: eclampsia, HELLP syndrome, DIC, pulmonary edema, abruption placentae, renal failure.
Neonatal outcome: gestational age at delivery, birth weight, Apgar score, patent ductus arteriosus, RDS, PVL, IVH, NEC, days in NICU.
Statistical procedure Simon minimax plan; P0: 60%, P1, 90%, alpha error: 5%, beta power; 90%. First step: number 8 patients. If success equal or less than 5, the study is stopped.

What is being measured
The primary outcome is the main question the study is designed to answer.
Baby discharged alive or alive at 6 months if hospitalized
During the first step (inclusion of 8 patients) analysis is done continuously, and if 3 women have unsuccess primary endpoint, first step and the study are stopped, with a conclusion of failure of the procedure of lipapheresis.
Measured: 6 months

Measured: 11 weeks
Circulating levels of sFlt1, the placental growth factor (PlGF) and soluble endoglin (sEng) until deliverance
For the measure of the maternal adsorptive efficiency, the following parameters will be described: circulating levels of sFlt1, the placental growth factor (PlGF) and soluble endoglin (sEng).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Introduction Preeclampsia is a multifactorial disease that is responsible of important adverse maternal and perinatal outcomes. Recently, it has been suggested that soluble fms-like tyrosine kinase 1, s-Flt1, induces preeclampsia-like phenotype in experimental models and circulates at elevated levels in human preeclampsia.
The aim of our study is to see whether removal of s-Flt1 may improve perinatal death in women with very early severe preeclampsia at less than 26 weeks' gestation Patients and methods Phase II trial. Women with singleton pregnancy having severe preeclampsia at 23-256/7 weeks' gestation. Women under 18 years, with multiples, or severe fetal growth restriction (less than 5th centile), or abnormal fetal heart rate, or maternal complications (abruption, eclampsia, HELLP syndrome, pulmonary edema, DIC, liver hematoma) are excluded from the study. After blood pressure and maternal stabilization, women are approached for information and if they agree, to sign the trial consent.
Women have twice weekly extracorporeal removal of s-Flt1 until 34 weeks' gestation.
Primary endpoint or success of the procedure: baby alive or alive at 6 months if hospitalized Statistical procedure Simon minimax plan; P0: 60%, P1, 90%, alpha error: 5%, beta power; 90%. First step: number 8 patients. If success equal or less than 5, the study is stopped.
Second step: if success of 6 or more, the study is continued for 9 more patients.
Overall, a maximum of 17 patients will be included. The final success of extracorporeal removal of s-Flt1 will be considered if 14 or more babies will be alive or alive at 6 months if hospitalized.
