Inclusion criteria |
1. The age is required to be greater than or equal to 18 years old and less than 81 years old, with no gender limitation. 2. The modified Rankin Scale (mRS) score before the onset of this episode should be less than or equal to 1 point. 3. The drug can be administered within 24 hours after the appearance of symptoms and signs of neurological deficits (for subjects with wake-up stroke or unwitnessed stroke, the time when the patient was last known to be normal shall be regarded as the onset time of symptoms). 4. The clinical symptoms, signs and imaging diagnosis indicate cerebral infarction in the blood supply area of the middle cerebral artery, and the following characteristics should be met simultaneously: (1) The National Institutes of Health Stroke Scale (NIHSS) score should be greater than or equal to 16 points and less than or equal to 32 points, and the sum of the scores for item 5 (upper limb) and item 6 (lower limb) should be greater than or equal to 6 points. (2) Imaging suggests that for the infarct core area: the volume of the lesion with cerebral blood flow (CBF) less than 30% in computed tomography perfusion imaging (CTP) or the volume of the lesion with an apparent diffusion coefficient (ADC) value less than 620 × 10^-6mm^2/s in the diffusion-weighted imaging (DWI) sequence of magnetic resonance imaging (MRI) is between 70 ml and 300 ml, or the Alberta Stroke Program Early CT Score (ASPECTS) is between 0 and 6 points. The results of CTP examination shall be given priority. If both CTP and DWI are completed during the screening period and the examination results are inconsistent, the investigator shall comprehensively consider all information (scanning time, imaging methods that best reflect the size of the infarct, etc.) to make a reasonable judgment and record it. The ASPECTS score can be based on either CTP or MRI, but CTP shall be given priority. 5. If vascular reperfusion treatment has been carried out and the treatment effect is poor, the following conditions should be met simultaneously: (1) The expanded Thrombolysis in Cerebral Infarction (eTICI) grade is equal to 2a. (2) The NIHSS score has not improved or has progressed after vascular reperfusion treatment, and the total score is still less than or equal to 32 points. Note: A reduction of 1 point or more is considered as improvement, and an increase of 1 point or more is considered as progress. 6. The subject or his/her legal representative voluntarily signs the informed consent form. |

随机方法(请说明由何人用什么方法产生随机序列): |
受试者按照1:1比例进行随机分配试验组(RK-4注射液颅骨给药)及对照组(常规治疗),随机数字表利用SAS软件产生。 本试验采用中央化竞争入组随机方法,每位受试者在签署知情同意书后,且在进行研究相关检查之前,将分配到一个“筛选号”。筛选号由中心序号(2位)+本中心筛选序号(3位)组成,如01001,01002,...,以此类推,受试者筛选号不得重复使用。 受试者筛选合格后,研究者或其指定人员通过随机化分组系统获取随机号以及组别。 随机化分层因素包括:研究中心。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Subjects were randomly assigned to the experimental group (RK-4 injection administered via the skull) and the control group (conventional treatment) at a 1:1 ratio. The random number table was generated using SAS software. This trial adopted a centralized competitive enrollment randomization method. After each subject signed the informed consent form and before undergoing research-related examinations, they would be assigned a "screening number". The screening number consisted of the center serial number (two digits) + the screening serial number of this center (three digits), such as 01001, 01002, and so on. The screening numbers of subjects could not be reused. After the subjects were screened as qualified, the investigator or the person designated by them obtained the randomization number and the group assignment through the randomization grouping system. The randomization stratification factors included: research center. |
