研究目的:

在接受机械取栓并于术中造影确认达到 eTICI 2c–3 完全再通的急性前循环大血管闭塞患者中,评价完全再通后即刻局部动脉内(IA)注射替罗非班相较于对照策略,是否能够“提高 90 d(±7 d)优良功能结局(mRS 0–1)”的比例。  

Objectives of Study:

In patients with acute anterior-circulation large-vessel occlusion who undergo mechanical thrombectomy and are confirmed by intraoperative angiography to have achieved complete reperfusion (eTICI 2c–3), to evaluate whether immediate local intra-arterial (IA) injection of tirofiban after complete reperfusion, compared with the control strategy, can increase the proportion of patients achieving a favorable functional outcome at 90 days (±7 days) (mRS 0–1).

随机方法(请说明由何人用什么方法产生随机序列):

由独立统计人员采用计算机生成的区组随机方法产生1:1分配随机数列。随机序列由非研究实施人员保存并管理,研究中心在受试者满足入组条件、术中最终造影确认达到eTICI 2c–3完全再通且完成随机前核查后,按预设随机序列进行分组。

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

The randomization sequence will be generated independently by a statistician using a computer-based block randomization method with a 1:1 allocation ratio. The sequence will be maintained by personnel not involved in trial intervention. Eligible participants will be randomized after final intraoperative angiography confirms eTICI 2c–3 complete reperfusion and pre-randomization checks are completed.

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:

本研究采用标准化病例报告表(CRF)和电子数据采集/管理系统(EDC)进行数据采集与管理。各中心研究人员按照统一操作规范收集受试者基线资料、影像学信息、围术期操作信息、实验室检查结果、不良事件及随访结局,并及时录入EDC系统。研究数据实行受试者唯一识别编码管理,去除可直接识别个人身份的信息,确保受试者隐私与数据安全。项目设数据核查与质控流程,对录入数据进行逻辑检查、缺失值核查和一致性核对;对重要终点事件及安全性事件进行重点审核。所有研究资料按照伦理要求和研究单位档案管理规定保存。

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

Study data will be collected and managed using standardized case report forms (CRFs) and an electronic data capture/management system (EDC). Investigators at each site will collect baseline characteristics, imaging data, periprocedural information, laboratory results, adverse events, and follow-up outcomes according to unified study procedures, and enter the data into the EDC system in a timely manner. All participants will be managed using unique study identification codes, and directly identifiable personal information will be removed to protect privacy and data security. Data quality control procedures will include logic checks, missing data review, and consistency verification. Key efficacy and safety outcomes will undergo focused review. All study records will be archived in accordance with ethics requirements and institutional document management policies.
