An interventional study of Statins and/or Ezetimibe and PCSK9 inhibitor in Ischemic Stroke, Small Vessel Cerebrovascular Disease and Cholesterol, LDL, sponsored by Seoul National University Hospital. Recruiting at 46 sites in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2026-09-11.

Lipid-lowering therapy constitutes a cornerstone of secondary prevention in ischemic stroke; however, current stroke guidelines remain deficient in providing optimal target low-density lipoprotein (LDL)-cholesterol levels tailored to the stroke subtypes. Most clinical trials on LDL-cholesterol management have not differentiated between stroke subtypes or have primarily focused on large artery atherosclerosis (LAA) stroke, leaving a gap in evidence for managing LDL-cholesterol in other stroke subtypes, e.g., small vessel occlusion (SVO) stroke. While hypertension is the leading risk factor for SVO strokes, the link between elevated LDL-cholesterol and SVO stroke is also recognized. Establishing optimal LDL-cholesterol targets for SVO stroke would significantly enhance secondary prevention strategies and improve patient outcome. Thus, the investigators aim to compare intensive versus standard lipid-lowering in patients with SVO stroke. SVO70 is a multicenter, prospective, randomized, open, blinded-endpoint clinical trial. Adult participants with objectively confirmed SVO stroke within 180 days of randomization will be included. Exclusion criteria include those with predefined LDL-cholesterol targets for other conditions, baseline LDL-cholesterol \<70 mg/dL in the absence of lipid-lowering therapy, statin contraindications, or women who are pregnant, breastfeeding, or planning pregnancy during the study period. Eligible participants will be randomized 1:1 to target LDL-cholesterol \<70 mg/dL (intensive group) or 90-110 mg/dL (standard group). The trial plans to enroll 4,016 participants, with the primary outcome being major adverse cardiovascular events-cardiovascular death, stroke, and acute coronary syndrome-during a follow-up period of at least 4 years. This study would provide valuable information for determining the optimal LDL-cholesterol target for patients with SVO stroke.

Exclusion Criteria:
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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
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.
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.
