Objectives of Study: |
1. Primary Objective: To preliminarily evaluate the safety of early tirofiban administration (within 4–24 hours) after intravenous reteplase thrombolysis in patients with acute ischemic stroke (AIS), with the incidence of symptomatic intracranial hemorrhage (sICH) within 48 hours defined as the primary safety endpoint. 2. Secondary Objectives: To preliminarily assess the effect of early tirofiban following reteplase thrombolysis on favorable functional outcome at 90 days (modified Rankin Scale [mRS] score 0–1); To evaluate its impact on functional independence at 90 days (mRS score 0–2); To explore associations with secondary outcomes including early neurological deterioration and recurrent stroke; To identify the optimal time window for tirofiban initiation after reteplase thrombolysis. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
去标识化受试者原始数据、试验方案、知情同意书、统计分析计划,在试验完成+数据库锁定后,合格研究者可向通讯作者书面申请获取;申请者需附带二次研究伦理批件与研究方案,审核通过后30个工作日加密传输原始数据;数据库锁定前不开放数据。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
De-identified individual participant data (IPD), trial protocol, informed consent form, statistical analysis plan will be available to qualified researchers upon formal written request to the corresponding author after trial completion and primary data lock. Requestors need to submit a formal data access application with a detailed statistical analysis plan and ethical approval document for secondary research. Data will be delivered via encrypted secure file transmission within 30 working days after approval. No raw data will be shared before trial database lock to avoid unplanned interim analysis. |
|
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: |
1. 数据采集:依据研究方案设计统一CRF表格,前瞻性收集受试者基线资料、脑血管危险因素、卒中分型、D-二聚体等检验指标、头颅影像学、干预方案及各访视点疗效、安全性随访数据;所有入组研究者统一培训后填写CRF,原始住院病历、化验单、影像报告作为源文件在本院病案室存档,CRF内容全部可溯源至源文件。受试者分配唯一研究编号,隐去姓名、身份证号等隐私信息,实现数据去标识化,符合GCP及医院伦理隐私管理要求。 2. 数据管理:纸质CRF汇总后由两名独立研究人员双份录入ResMan在线EDC系统,系统自带逻辑校验、值域限定规则,自动识别异常、缺项数据;数据管理员定期发质疑,研究者核对原始病历完成答疑修正;全部受试者随访结束后完成全量数据清理,执行数据库锁定,锁定后不得随意修改数据;最终清理后的数据同步导出Excel存档备查。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Standardized case report forms (CRFs) were designed according to the study protocol to prospectively collect participants’ baseline characteristics, cerebrovascular risk factors, stroke classification, laboratory indicators including D-dimer, cranial imaging results, intervention measures, and efficacy and safety data at each follow-up time point. All investigators received unified training before data collection. Original medical records, laboratory reports and imaging data were retained in the hospital archives as source documents to ensure full traceability. Each participant was assigned a unique study identification number, and all personal identifiable information was removed for de-identification in accordance with GCP guidelines and ethical privacy requirements. All paper CRF data were independently double-entered into the ResMan electronic data capture (EDC) system. The system automatically performed logical verification and range validation to identify missing or inconsistent data. Data queries were regularly generated and resolved by investigators based on original source records. Systematic data cleaning was conducted after completion of all follow-up visits, and the database was formally locked to prevent any unauthorized modification. The final dataset was exported and saved in Excel format for archiving and future analysis. |
