Preeclampsia Intervention 4 - A Triple Blind Phase III Randomised Controlled Trial Assessing Metformin to Prolong Gestation in Preterm Preeclampsia
Preterm preeclampsia is a severe condition for both the mother and the fetus. Currently, the only treatment available to stop disease progression is termination/delivery of the fetus and placenta. Therefore, preterm preeclampsia carries the highest rates of neonatal morbidity and mortality due to iatrogenic preterm birth. There is evidence suggesting metformin, a drug commonly used to treat diabetes in and outside pregnancy, may be able to counter the pathophysiology of preeclampsia, raising the possibility that it could be used to treat the condition. This multi centre double blind randomised controlled trial aims to investigate if metformin can prolong gestation, lower neonatal length of stay and increase birthweight in a Swedish setting.
• A diagnosis of preeclampsia (defined as hypertension in combination with significant proteinuria (albumin/creatinine ratio \>8 mg/mmol, protein/creatinine ratio\>30 mg/mmol or \>2+ protein on a urinary dipstick) has been made by the attending clinician
• The managing clinicians have made the assessment to proceed with expectant management.
• The subject has given written consent to participate in the study.
• The woman must be 18 years of age or older
• The gestational age is between 22+0 weeks to 33+6 weeks with a viable fetus
• The woman carries a singleton pregnancy
