E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of the trial is to establish whether pravastatin will lead to a significant reduction of circulating anti-angiogenic factors in women with early-onset pre-eclampsia. To test this hypothesis, we will ask the following questions: 1. Does pravastatin cause a greater inhibition of circulating anti-angiogenic factors in women with early-onset pre-eclampsia compared with placebo? 2. Are there any beneficial or adverse clinical effects to the mother or the baby following gestational exposure to pravastatin? 3. If pravastatin appears to safely inhibit circulatating anti-angiogenic factors, how best can a substantive trial/health technology assessment be undertaken to develop guidance for routine use of statins to prevent or ameliorate pre-eclampsia?
|
|
E.2.2 | Secondary objectives of the trial |
Should data from this trial suggest that statins are a promising therapy for pre-eclampsia, a larger substantive trial will be developed in asymptomatic women at risk of pre-eclampsia to answer the following questions: 1. Can statins delay progression to pre-eclampsia in women at high-risk of the condition? 2. Can pravastatin reduce the severity of early-onset pre-eclampsia and if so, how much additional gestational time can be gained? 2. Do statins improve fetal and maternal outcome? 3. What are the rates of any adverse effects to the mother or the baby?

E.3 | Principal inclusion criteria |
In order to be randomised into the StAmP trial, all eligibility criteria must be satisfied. Investigators will be asked to confirm each eligibility criteria at randomisation. Inclusion Criteria: To be eligible for the StAmP Trial, the women must: 1. Aged above 16 years 2. Be between 24+0 weeks’ and 31+6 weeks’ gestation 3. Have a singleton pregnancy 4. Have a diagnosis of early onset Pre-eclampsia (according to definition below) 5. Be considered capable of safely continuing the pregnancy for 48 hours or more, as determined by the attending clinician 6. Obstetrician and neonatologist believe the fetus is likely to be viable 7. No major anomalies evident on the 20-week anomaly scan. Any anomaly should be assessed by the Principal Investigator and discussed with the Chief Investigator, following classification of the anomaly according to the ICD10 codes. All major anomalies will be excluded, but minor anomalies, subject to agreement between the PI and CI will be included 8. Be capable of understanding the information provided, with use of an interpreter if required 9. Give written informed consent
Definition of Pre-eclampsia (24-31+6 weeks gestation) The minimum clinical criteria required to establish a diagnosis of pre-eclampsia are the first two criteria below. The third criterion is relevant if there is chronic hypertension, preceding pregnancy. The other criteria (4-6) are often present in early pre-eclampsia, but are not essential for diagnosis for pre-eclampsia. 1. New onset hypertension after 20 weeks gestation defined as diastolic BP greater than 90 mmHg, using Korotkoff sound 5 to define the diastolic level. 2. New onset proteinuria 2+ or more on standard urinary dipstick tests confirmed by proteinuria PCR ratio of greater than 30mg/mmol on spot urine test or >300mg/24 hours on a 24 hour urine collection. 3. Women who have chronic hypertension, the appearance of new onset proteinuria, (defined above), a sudden increase of blood pressure, thrombocytopenia (platelets <100), elevated transaminases, or a sudden increase in proteinuria in those who have pre-existing proteinuria. 4. Liver transaminases may be increased 5. Serum creatinine (SCr) may be increased 6. Platelet count may be decreased |
|
E.4 | Principal exclusion criteria |
Any women, who at the point of randomisation, exhibit any of the following are not eligible for the trial: 1. Eclampsia 2. Current use of statins 3. Contraindications to statin use (other than pregnancy) including: - Hypersensitivity to pravastatin or any of its excipients - Active liver disease or elevation of serum transaminases not thought to be related to pre-eclampsia - Pre-pregnant renal insufficiency (creatine clearance <30ml/min) - Concomitant administration of potent CYP3A4 inhibitors 4. Imminent transfer to a non-trial centre due to unavailability of neonatal cots. 5. Participation in any other blinded, placebo-controlled trials of investigational medicinal products in pregnancy. 6. Significant uncertainty regarding gestational age. Under 24 weeks' gestation, pregnancies are often not considered viable and therefore women with pre-eclampsia less than 24 weeks gestation will be excluded. Women with pre-eclampsia around 32 weeks’ gestation are often delivered when the mother is stable and therefore we will exclude women who develop pre-eclampsia over 32 weeks’ gestation. For this reason, if there is any uncertainty about the gestational age, the mother should not be approached for randomisation. 7. Women who are HIV or hepatitis B positive |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure will be the effect of pravastatin on sFlt-1 individually during the first 72 hours post-randomisation. |
