Preeclampsia is a condition that occurs in approximately 5-8% of pregnant mothers in the US, and 14% worldwide. It is characterized by high blood pressure and protein in the urine arising after the 20th week of gestation. There are currently no pharmaceuticals or medical devices approved for treatment of preeclampsia. Current treatment includes bed-rest, close monitoring of the mother's condition
with supportive measures, and prayer. The only cure for preeclampsia is to delivery the baby, often prematurely. Preeclampsia is the leading cause of preterm births, maternal death (approx. 76,000 annually), and accounts for over 10,000 infant deaths in the US and approximately 500,000 infant deaths worldwide each year. Advanced Prenatal Therapeutics targeted therapy for preeclampsia is a simple procedure in which disease-causing factors in the mother's blood are specifically removed with APT's Targeted Apheresis Column for Preeclampsia (TAC-PE), while the blood components that are natural and vital are preserved. APT's mission is to develop an effective treatment that will safely prolong pregnancy, allowing babies more time to develop in the womb. Treatment with the TAC-PE will potentially extend the duration of pregnancy, thereby reducing the risk of lifelong disabilities in babies resulting from prematurity and IUGR. Apheresis is a common and safe procedure used therapeutically to treat several chronic diseases, even during pregnancy. Apheresis is a process similar to kidney dialysis in which whole blood is removed from a patient, filtered for a particular substance, and then returned to the patient. Our patent pending technology selectively targets the removal of blood components associated with the symptoms of preeclampsia. Specifically, the TAC-PE removes the harmful sFlt-1 receptors, thereby freeing circulating growth factors to bind to their target receptors in the mother. The TAC-PE is an affinity column that can be integrated into existing therapeutic apheresis devices. It consists of a rigid cylinder filled with immobilized agarose beads conjugated to proprietary sFlt-1 antibodies. To treat the patient, the woman's blood is pumped through an apheresis machine (1), which separates her blood into plasma and blood cells (2). The plasma is then circulated through the TAC-PE device (3), where the harmful sFlt-1 proteins are captured. The cleaned plasma is then remixed with the blood cells (4) and returned to the patient (5).
