Esomeprazole in Treatment of Early Onset Preeclampsia (ESOPE Trial)
Study Details
Study Description
Brief Summary
Pre-eclampsia is one of the most serious complications of pregnancy affecting 3-8 % of pregnancies worldwide. It is a multi-system disorder involving maternal vessels (causing hypertension and endothelial dysfunction), the kidneys, the liver, the lungs, the hematological system, the cardiovascular system and the feto-placental unit. In its most severe form, it affects the brain, causing seizures (eclampsia), cerebro-vascular events and even death.

Phase 2/Phase 3 |
Detailed Description
The key aspects in the pathophysiology of pre-eclampsia are placental oxidative stress (and hypoxia), placental release of the anti-angiogenic factors Soluble Fms Like Tyrosine Kinase -1 and soluble endoglin and maternal endothelial dysfunction. A drug that can counter these pathological steps could be a strategy to treat pre-eclampsia.
If an affordable and safe treatment was available it could temporize the disease progression of pre-eclampsia thereby delaying delivery to gain gestation. This could save the lives of many infants and decrease the hospital burden caused by iatrogenic prematurity.
Currently, there are trials investigating the possible use of pravastatin to treat pre-eclampsia, and to prevent it There are no other significant trials of orally available small molecules to treat pre-eclampsia that we are aware of.
The Translational Obstetrics Group at Melbourne University has generated strong preclinical evidence suggesting esomeprazole as one of the proton pump inhibitors may have potent actions giving it significant potential as a treatment for pre-eclampsia
Proton pump inhibitors have been commonly used in pregnancy to treat gastroesophageal reflux disorders and more serious gastrointestinal complications like Helicobacter pylori-infection, peptic and duodenal ulcers and Zollinger-Ellison syndrome.
Esomeprazole counters three key steps in pre-eclampsia pathogenesis, by up-regulating heme oxygenase-1 ( strongly decreasing the release of antiangiogenic factors Soluble Fms Like Tyrosine Kinase -1 and soluble endoglin and quenching endothelial dysfunction.
