Study summary

A recent randomized controlled trial by Cluver et al included 180 women with preterm pre-eclampsia between 26+0 to 31+6 weeks' gestation undergoing expectant management: 90 were randomised to extended release metformin and 90 to placebo. Investigators found that extended release metformin (3g daily) can prolong gestation in women with preterm pre-eclampsia. Combination metformin and esomeprazole has shown promise in the treatment of preeclampsia as both agents reduce placental and endothelial secretion of soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin, and reduce endothelial dysfunction.

Inclusion criteria

Individuals presenting with pre-eclampsia between 24+0 and 31+6 weeks of gestation, with a single viable fetus and no major anomalies

  • Women 18 years or older
  • Women diagnosed with preeclampsia
  • Women with pre-eclampsia superimposed on chronic hypertension
  • Candidates for expectant management and had no clinical indication for immediate delivery

Exclusion criteria

Exclusion Criteria:

  • Delivery within 48hr is highly likely
  • Maternal or fetal compromise that necessitated immediate delivery
  • Diabetes or gestational diabetes currently on metformin therapy
  • to metformin, esomeprazole
  • Baseline creatinine >124 μmol/L
  • to metformin or esomeprazole
  • Metabolic acidosis
  • Use of drugs that might interact with metformin (glyburide, furosemide, or cationic drugs) Multiple gestations
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Mar 2023; primary completion for Dec 2024, 21 months later.

Of 20 phase 1 interventional studies under Pre-Eclampsia, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 34. This study's planned 21 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 10, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
