Cholesterol drug tested to stop dangerous pregnancy complication
NCT ID NCT03944512
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether the cholesterol-lowering drug pravastatin could prevent preeclampsia in women who had a previous early preterm delivery due to the condition. The trial planned to enroll 1,550 women but was terminated early with only 102 participants. Because it stopped early, the results are not strong enough to draw clear conclusions about whether pravastatin helps or is safe in pregnancy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pravastatin (a statin drug, typically used for cholesterol)
- What this could lead to
- If it had worked, this could have pointed toward a way to prevent preeclampsia in women at high risk, potentially saving lives and preventing complications.
- What could go wrong
- The trial was terminated early with only 102 participants instead of the planned 1,550, so results are very limited and not reliable. Statins are generally not recommended in pregnancy due to safety concerns.

Inclusion Criteria: 1. 16 years or older at time of consent with ability to give informed consent 2. Single or twin gestation with cardiac activity in one or both fetuses. Higher order multifetal gestations reduced to twins, either spontaneously or therapeutically, are not eligible unless the reduction occurred by 13 weeks 6 days project gestational age. 3. Gestational age at randomization between 12 weeks 0 days and 16 weeks 6 days based on clinical information and evaluation of the earliest ultrasound. 4. Documented history (by chart or delivery/operative note review) of prior preeclampsia with delivery less than or equal to 34 weeks 0 days gestation in any previous pregnancy. If in the index pregnancy, the woman was induced by 34 weeks 0 days gestation and delivered within 48 hours in the same hospitalization, that woman would be eligible. 5. Normal serum transaminase (AST/ALT) concentrations documented in the last 6 months. Exclusion Criteria: 1. Monoamniotic gestation because of the risk of fetal demise 2. Known chromosomal, genetic or major malformations 3. Fetal demise or planned termination of pregnancy. Selective reduction by 13 weeks 6 days gestation, from triplets to twins or twins to singleton is not an exclusion. 4. Contraindications for statin therapy: 1. Hypersensitivity to pravastatin or any component of the product 2. Active liver disease: acute hepatitis or chronic active hepatitis 5. Statin use in current pregnancy 6. Patients with any of the following medical conditions: 1. Uncontrolled hypothyroidism with a TSH level above 10 mIU/L, because of increased risk of myopathy 2. HIV positive, because of increased risk of myopathy with use of protease inhibitors 3. Chronic renal disease with baseline serum creatinine ≥1.5 mg/dL, because of association with adverse pregnancy outcomes 7. Current use of concomitant medication with potential for drug interaction with statins (i.e.,, cyclosporine, fibrates, niacin, erythromycin). Patients will not be excluded if the drug is discontinued (at least one week) prior to randomization. 8. Participating in another intervention study that influences the primary outcome in this study 9. Plan to deliver in a non-network site 10. Participation in this trial in a previous pregnancy. Patients who were screened in a previous pregnancy, but not randomized, do not have to be excluded.
