SATURN is a multi-center, pragmatic, prospective, randomized, open-label, and blinded end-point assessment (PROBE) clinical trial. A total of 1,456 patients presenting within 7 days of a spontaneous lobar ICH while taking statins will be randomized to one of two treatment strategies: discontinuation vs. continuation of statin therapy (using the same agent and dose that they were using at ICH onset). Participating subjects will undergo baseline testing for APOE genotype and will be followed for 24 months to assess for the occurrence of recurrent symptomatic ICH or major adverse cerebro-/cardio-vascular events (MACCE) during the follow-up period. A subset of SATURN participants will participate in the optional MRI study, where they will undergo a baseline MRI within 7 days of randomization into SATURN and a repeat MRI at the end of the follow-up period. Recruitment will take place at ~ 140 sites coordinated through the NIH/NINDS StrokeNet and the Canadian Stroke Consortium.
Inclusion Criteria: 1. Age ≥ 50 years. 2. Spontaneous lobar ICH confirmed by CT or MRI scan 3. Patient was taking a statin drug at the onset of the qualifying/index ICH 4. Randomization can be carried out within 7 days of the onset of the qualifying ICH 5. Patient or legally authorized representative, after consultation with the statin prescriber, agrees to be randomized to statin continuation (restart) vs. discontinuation Exclusion Criteria: 1. Suspected secondary cause for the qualifying ICH, such as an underlying vascular abnormality or tumor, trauma, venous infarction, or hemorrhagic transformation of an ischemic infarct. 2. History of recent myocardial infarction (attributed to coronary artery disease) or unstable angina within the previous 3 months 3. Diabetic patients with history of myocardial infarction or coronary revascularization 4. History of familial hypercholesterolemia 5. Patients receiving proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors 6. Known diagnosis of severe dementia 7. Inability to obtain informed consent 8. Patients known or suspected of not being able to comply with the study protocol due to alcoholism, drug dependency, or other obvious reasons for noncompliance, such as unable to adhere to the protocol specified visits/assessments. 9. Life expectancy of less than 24 months due to co-morbid terminal conditions. 10. Pre-morbid mRS >3 11. ICH score >3 upon presentation. 12. Contraindications to continuation/resumption of statin therapy, such as significant elevations of serum creatinine kinase and/or liver transaminases, and rhabdomyolysis 13. Woman of childbearing potential 14. Concurrent participation in another research protocol for investigation of experimental therapy. 15. Indication that withdrawal of care will be implemented for the qualifying ICH.
