Summary

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 Nordic setting.

Conditions

Interventions

DRUG

Metformin ER

Metformin ER, one gram three times daily taken orally. Once the participants have been recruited, they will start by taking one 500 mg tablet three times a day. If well tolerated it will be increased day two to a maximum of two tablets three times a day. Treatment will continue until delivery. If there are side effects that are not tolerable, the dose will be decreased and the participant will remain blinded. Each participant will keep a treatment diary and number of tablets taken will be documented by the participant or hospital staff. The study will not alter or interfere with treatment or care routinely given for preterm preeclampsia.

DRUG

Placebo

Placebo, two tablets three times daily taken orally. Once the participants have been recruited, they will start by taking one tablet three times a day. If well tolerated it will be increased day two to a maximum of two tablets three times a day. Treatment will continue until delivery. If there are side effects that are not tolerable, the dose will be decreased and the participant will remain blinded. Each participant will keep a treatment diary and number of tablets taken will be documented by the participant or hospital staff. The study will not alter or interfere with treatment or care routinely given for preterm preeclampsia.
