随机方法(请说明由何人用什么方法产生随机序列):

符合所有纳入标准且不符合任何排除标准的患者按 1:1 的比例随机分配至阿加曲班组和对照组。各分中心研究者在患者签署知情同意书后报告组长单位研究者,由主中心确定符合研究标准后,由主中心采用中央随机化系统生成随机号。

Randomization Procedure (please state who generates the random number sequence and by what method):

Patients who met all inclusion criteria and did not meet any exclusion criteria were randomly assigned to the argatroban group and the control group in a 1:1 ratio. After patients signed the informed consent form, researchers at each sub-center reported to the researchers at the leading unit. After the main center confirmed that the patients met the study criteria, the main center generated random numbers using a central randomization system.

盲法:

采用开放标签,终点盲法,即患者和治疗医生对治疗分配知情,但研究结果评估人员对治疗分配不知情。建立独立、盲态的终点事件判定委员会(Endpoint Adjudication Committee, EAC)。该委员会由独立于治疗组的脑卒中医生组成,EAC不可接触研究对象病历资料和参与诊疗过程,基于预设的标准,盲法判定每个疑似END事件是否符合方案,90天mRS评分使用标准化内容进行提问,确保评分准确性

Blinding:

An open-label, endpoint-blinded design was adopted, meaning that patients and treating physicians were aware of the treatment allocation, while researchers assessing study outcomes were unaware of the treatment allocation. An independent and blinded Endpoint Adjudication Committee (EAC) was established. The committee consists of stroke physicians who are independent of the treatment groups. The EAC has no access to the medical records of the study subjects and does not participate in the diagnosis and treatment process. Based on preset criteria, the committee makes blinded determinations on whether each suspected END event conforms to the protocol. The 90-day mRS score is assessed using standardized questions to ensure the accuracy of the score.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

所有研究对象数据均通过纸质版CRF表进行收集后,通过主中心进行电子版CRF表录入和校对。所有分中心的主要研究人员均获得良好临床规范认证。临床检查员应定期访问分中心,以确保严格遵守方案并确保原始数据和CRF数据的一致性。 研究设立独立的数据安全和监查委员会(Data and Safety Monitoring Boards, DSMB),负责在执行阶段对试验是否终止/继续提供建议。数据和安全性监查委员会成员由丰富经验的神经科医师、神经介入医师及统计学家共同组成,成员均不参与临床试验的执行,数据和安全性监查委员会由数据和安全性监查委员会主席组建,根据数据和安全性监查委员会工作章程工作。数据和安全性监查委员会详细审查所有临床及安全终点事件。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data of all subjects were collected through the paper of Case Report Forms (CRFs), and then entered into and verified in electronic CRFs by the main center. All principal investigators from sub-centers have obtained Good Clinical Practice (GCP) certification. Clinical inspectors should conduct regular visits to sub-centers to ensure strict compliance with the protocol and consistency between original data and CRF data.? An independent Data and Safety Monitoring Board (DSMB) was established for the study, which is responsible for providing suggestions on whether to terminate or continue the trial during the implementation phase. Members of the DSMB consist of experienced neurologists, neurointerventionalists, and statisticians, all of whom are not involved in the execution of the clinical trial. The DSMB is organized by its chairperson and operates in accordance with the DSMB's working charter. The DSMB conducts a detailed review of all clinical and safety endpoint events.
