Stroke, Acute Ischemic Clinical Trial
Official title:
The Effect of Early Administration of PCSK9 Inhibitor, Alirocumab to Acute Ischemic Stroke Patients Associated With Atherosclerosis on the Stroke Prognosis and Lipid Profile, a Single Center Study, Registry Based, Pragmatic, Prospective Trial
The goal of this clinical trial is to test the effect of proprotein convertase subtilisin/kexin type 9 (PCSK9 inhibitors) in acute ischemic stroke patients associated with atherosclerosis by investigating 1. the change in lipid profile compared to baseline results 2. the effects on prognosis of stroke The participants will be given PCSK9 inhibitor right after confirmation of acute ischemic stroke, and the investigators will compare the results to the control group, whom are acute ischemic stroke patients treated with conventional lipid lowering therapy, statin and/or ezetimibe.
This clinical trial will be recommended to patients aged 19 and older who are admitted with ischemic stroke accompanied by atherosclerosis of large arteries, rather than cardiac embolism. Upon confirmation of ischemic stroke through CT and MRI in the emergency room, the patient will be provided with a detailed explanation of the future treatment plan and the purpose of this study. Depending on the day of the week, the patient will be randomly assigned to the treatment group (alirocumab + high-dose statin group) and the control group (high-dose statin group) in a 1:1 ratio. For those in the treatment group, alirocumab (brand name: Praluent Pen) 300mg will be administered as a single dose. Both the treatment and control groups will receive standard diagnostic tests and treatments as conventional stroke patients unrelated to the clinical trial. Blood samples collected for testing will be promptly discarded by the hospital's diagnostic laboratory. Both groups will have outpatient visits one month after discharge. The investigators are planning on total 200 patients enrollment (100 treatment group + 100 control group). For categorical variables, frequency and percentage will be provided, and for continous variables, mean and standard deviation will be provided. All statistical tests used for analysis will be two-tailed. Statistical significance will be tested at a 5% significance level. If necessary, two-sided 95% confidence intervals will be provided. In the analysis of the entire registered patient population, not only univariate analysis but also multivariate analysis (Cox proportional hazard regression model) will be conducted to adjust for other factors. Detailed techniques for data summary and statistical analysis from the data collected in this clinical trial will be specified in the Statistical Analysis Plan (SAP). When sided effects or adverse events occur, the Principal Investigator is required to promptly report safety information, which includes occurrences of serious adverse events and drug-related adverse reactions, to the Institutional Review Board (IRB) of the trial institution within the timeframe specified in the trial institution's standard operating procedures during the trial period. Upon becoming aware of all occurrences of serious adverse events and special situations, regardless of their causality with the investigational product, the Principal Investigator will complete a 'Serious Adverse Event Report/Adverse Event of Special Situation' within 24 hours. ;
