Treat Stroke to Target
Treat Stroke to Target
The aim of this study is the evaluation of two usual care strategies after stroke or TIA :
 achieved target LDL-C of 100 mg/dL (+/-10 mg/dL) or less than 70 mg/dL. Investigators will
 use the statin and titrate the dosage to achieve the target assigned by randomization in
 monotherapy or in combination with ezetimibe or other drugs.

 The primary end-point is the occurrence of recurrent non fatal stroke, non fatal MI, and
 vascular death in each group.

 3760 patients will be recruited and followed for eight and a half years maximum.

 Inclusion criteria:

 -  Recent (less than 3 months) ischemic stroke As soon as possible after the event, once
 the neurologic deficit is stabilized (investigator judgment). These ischemic strokes
 include TIA with ischemic lesion documented by CT or MRI.

 -  Or recent TIA (less than 15 days) without documentation of ischemic lesion on CT/MR
 imaging. Must be limb weakness or aphasia lasting more than 10 min.

 -  And documented atherosclerotic stenosis in carotid artery (investigator judgment) (based
 on the results of Duplex echography, CTA, MRA or X ray- angiography), Or in the aortic
 arch (investigator judgment) (based on TEE or CTA), Or in other brain artery: vertebral,
 basilar or other intracranial artery (based on CTA, MRA, XRA), Or in coronary arteries
 (past history of acute coronary syndrome, coronary revascularization or positive
 coronary angiography)

 -  And statin treatment is indicated, following ANSM guidelines (French drug agency), age
 >18 years, rankin score ≤ 4, patient or a legal representative signs consent, patient is
 affiliated to social security system

 Exclusion criteria :

 -  Ischemic stroke/TIA du to arterial dissection (investigator judgment)

 -  Cardiac source of embolism (e.g., mitral stenosis, endomyocardial fibrosis) without
 documented atherosclerotic stenosis : a patient with atrial fibrillation or a past
 history of recent myocardial infarction or calcified aortic stenosis can be randomized
 if he otherwise fulfils inclusion criteria

 -  Symptomatic hemorrhagic stroke : Presence of microbleeds on gradient echo imaging (T2*)
 is not an exclusion criteria. Hemorrhagic transformation of an ischemic stroke is not an
 exclusion criteria

 -  Uncontrolled hypertension (investigator judgment)

 -  LDL-C <100 mg/dL or patients for whom treatment intensification is impossible

 -  F/U impossible or bad observance anticipated.

 -  Co-morbid condition that may interfere with the F/U or with the evaluation of primary
 endpoint

 -  Participation to another clinical trial

 The primary end-point is:

 Recurrent ischemic stroke or stroke of undetermined origin, myocardial infarction, urgent
 coronary or carotid revascularization following new symptoms requiring hospitalization, and
 vascular death.

 Secondary endpoints:

 -  Recurrent nonfatal ischemic stroke

 -  Nonfatal myocardial infarction

 -  Recurrent ischemic stroke, fatal or non

 -  Recurrent ischemic stroke or TIA

 -  Intracranial hemorrhage (intracerebral hemorrhage, subarachnoid hemorrhage, subdural
 hematoma)

 -  All stroke (ischemic or hemorrhagic)

 -  Any major coronary events (including fatal and nonfatal myocardial infarction)

 -  Any coronary heart disease end-point (myocardial infarction, hospitalization for acute
 corornary symptoms, coronary revascularization procedure)

 -  Any revascularisation procedure (coronary, carotid, or peripheral artery))

 -  Carotid artery revascularization procedure (urgent following new symptoms or elective)

 -  Vascular death (ischemic stroke or undetermined stroke, fatal myocardial infarction,
 other vascular deaths, sudden death, death of undetermined cause, i.e., without other
 cause documented such as cancer, infection, accident, suicide, etc…)

 -  All causes deaths

 -  Primary endpoint plus intracranial hemorrhage

 -  New onset diabetes

 Hypothesis :

 -  Follow-up of three years

 -  Risk of primary end-point in the control group (Target LDL <100 mg/dL) : 4% per year (12
 % at 36 months)

 -  5% Alpha, 80% power, total number of subject is :

 -  3068 patients with a RRR 25%

 -  20% drop-out: 3760 patients (385 primary EP)

 Study specifications Follow-up : eight and a half years Follow-up visit : every 6 months
 Number of centers (French Stroke Units, under the auspice of the French Neurovascular
 Society) : 60-100

 Ancillary study As an ancillary study, 800 patients (400 in each arm in 4 centers) will
 participate in the TST-PLUS (Plaque Ultrasound Study), in which they will have three
 ultrasound examination (baseline, 1 year and 3 years) and baseline blood sampling. The
 primary endpoint of this substudy will be the rate of occurrence of new carotid plaque, with
 the hypothesis that Rate of plaque occurrence in the <100 mg/dL group will be 25% after 3
 years (45% in EVA when atherosclerosis was present at baseline) RRR of plaque of 25% in the
 <70 mg/dL group Alpha 5%, power 80%

 As an ancillary study, 1000 patients will participate in the TST-PGS (Pharmacogenetics)
 Study, in which they will have 1 blood sampling either at baseline or during one of the
 follow-up visits of TST. The aim of this study is to show that the benefit (risk of ischemic
 stroke, myocardial infarction, and vascular death) observed with a strategy of LDL-C <0.7 g /
 l compared to a strategy of LDL-C to 1 ± 0.1 g / l is higher in carriers of polymorphism
 719Arg of the gene KIF-6 than non-carriers of this polymorphism.
