About this study
The primary goal of the trial is to investigate whether the lipid lowering strategy using Alirocumab plus statin could cause more changes from baseline in intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up, in patients with recent stroke/transient ischemic attack (TIA) caused by intracranial artery stenosis.
Read the detailed description
Intracranial atherosclerosis stenosis (ICAS) is one of the most common causes of stroke worldwide and is particularly prevalent in Asian. It accounts for up to 30-50% of strokes amongst Asian patient cohorts, in contrast to 5-10% of strokes amongst western patient cohorts. The SAMMPRIS established aggressive medical management (Intensive lipid lowering with statin to reach a low-density lipoprotein (LDL)-cholesterol lower than 1.8mmol/L, et al) as a superior choice for symptomatic ICAS compared to the percutaneous transluminal angioplasty and stenting. However, around 15% still had recurrent stroke or death during a median follow-up of 32.4 months in SAMMPRIS study in the aggressive medical management group.
Alirocumab, a member of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors, is a fully human monoclonal antibody that reduces LDL cholesterol levels by approximately 60%. The ODYSSEY OUTCOMES study showed that Alirocumab reduced the risk of cardiovascular events (e.g. cardiovascular death, myocardial infarction and stroke), in patients with atherosclerotic cardiovascular disease.
The proposed pilot study will recruit 50 patients with recent stroke/transient ischemic attack (TIA) caused by intracranial artery stenosis, and directly compare the differences before and after Alirocumab on top of statin therapy in changes of intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up.

What is being measured
The primary outcome is the main question the study is designed to answer.
Plaque burden (PB)
lumen area (LA) is manually contoured on T1-weighted SPACE at the most stenotic site (LAplaque). PB is calculated as (1 - LAplaque/OWAplauqe) × 100%
Measured: This will be assessed at 6 months after recruitment.
Degree of stenosis caused by the plaque
degree of stenosis = (1 - Dplaque/Dreference) × 100%, where Dplaque indicated the diameter of the culprit artery at the most stenotic site, and Dreference was the diameter of the normal artery proximal to the plaque
Measured: This will be assessed at 6 months after recruitment.
Plaque enhancement
grading of plaque enhancement: grade 0 indicated enhancement is similar to or less than that of normal-appearing intracranial arterial walls in the same individual; grade 1, enhancement is greater than that of grade 0 but less than that of the pituitary infundibulum; and grade 2, enhancement is similar to or greater than that of the infundibulum. plaque enhancement ratio (ER): circular region of interest (ROI) was drawn within the plaque on pre-contrast and post-contrast T1-weighted SPACE images, respectively. The mean signal intensity (SI) of plaques were obtained. ER = (SIpost - SIpre)/SIpre ×100%
Measured: This will be assessed at 6 months after recruitment.
Remodeling index (RI) of the plaque
the outer wall area (OWA) is manually contoured on T1-weighted SPACE at the most stenotic site (OWAplaque) and the reference site (OWAreference). RI is calculated as OWAplaque/OWAreference × 100%. Arterial remodeling is categorized as positive if RI > 1.05, intermediate if 0.95 ≤ RI ≤ 1.05, and negative if RI < 0.95;
Measured: This will be assessed at 6 months after recruitment.
Presence of T1 hyperintensity in the plaque
the brightest spot of the plaque with SI >150% of that of the reference vessel wall on pre-contrast T1 image
Measured: This will be assessed at 6 months after recruitment.
Plaque distribution: whether it is a concentric plaque or not
a concentric plaque is defined if the wall involvement was more than 75%, and the minimum wall thickness is higher than 50% of the maximum wall thickness.
Measured: This will be assessed at 6 months after recruitment.
Hemodynamic characteristics: Hypoperfusion volume
dynamic susceptibility contrast-perfusion weighted imaging (DSC-PWI) performed and computed using the singular value decomposition deconvolution method using a commercial software NeuBrainCARE (v1.1.10). Hypoperfusion volume on the ipsilateral side of stroke were automatically calculated by use of time to maximum (Tmax) with time thresholds of > 4 seconds and > 6 seconds, respectively.
Measured: This will be assessed at 6 months after recruitment.
Secondary outcomes (2)
Any stroke (ischemic or hemorrhagic) or death during 6 months of follow-up in an intention-to treat analysis.
Measured: This will be assessed during 6 months of follow-up.
Changes in LDL-cholesterol levels
Measured: This will be assessed during 6 months year of follow-up.

Questions about this trial
What is this clinical trial studying?
An observational study of Stroke and Intracranial Atherosclerotic Stenosis, run by The First Affiliated Hospital with Nanjing Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 28 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Zhaolu Wang, MD (18100613663, wangzhaolu123@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Plaque burden (PB) (time frame: This will be assessed at 6 months after recruitment.). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
