Exclusion Criteria

1. Multiple pregnancy
2. <16 years of age
3. Hypersensitivity to Pravastatin (active substance or any of the excipients)

9. ALT or AST above upper limit of normal (as set by local laboratories), to be taken at the time of screening*
10. Bilirubin above upper limit of normal (as set by local laboratories), to be taken at the time of screening*
11. Creatine Kinase (CK) concentration >5 times upper limit of normal (as set by local laboratories), to be taken at the time of screening
12. Currently breastfeeding
13. Unable to provide informed consent
14. Previously participated in PIONEER
15. Currently taking medicines or groups of medicines that are contraindicated for concomitant use with pravastatin§

* It is acknowledged that the Liver Function Test may include different assessments at different sites, therefore for the purpose of the screening blood test, the term Liver Function Test” at screening should include measurement of Bilirubin and at least one of ALT or AST. If any of these are above the upper limit of the normal, the person would not be eligible for inclusion in PIONEER, and should have ongoing follow-up according to local policy.
§ Those taking macrolides should be excluded from PIONEER, however, if a limited course of macrolides are prescribed with the course due to complete prior to 20+0 weeks’ gestation, then it may be possible to recruit to PIONEER following completion of the course of antibiotics (if completion of the course of antibiotics is prior to 20+0).
