Pharmacokinetics, Safety and Efficacy Study of Recombinant Antithrombin Versus Placebo in Preterm Preeclampsia

Summary

The purpose of the study is to assess the efficacy, safety and pharmacokinetics (PK) of recombinant human antithrombin (ATryn) in addition to expectant management for the treatment of preterm preeclampsia (PPE). Efficacy will be assessed by comparing the difference in extension of gestational age from the time of randomization into the study until delivery between ATryn and placebo treated subjects. In addition, the effect of ATryn on fetal and neonatal clinical outcomes will be assessed. The PK characteristics of ATryn in the subjects will be investigated by measuring AT activity levels in the mother during treatment and in cord blood.
