随机方法(请说明由何人用什么方法产生随机序列):

采用中心分层区组随机方法,实施中心控制随机分配的方法,即各参加单位受试者随机分配由临床试验中心统一控制。 对于具备随机化资格的患者,每家研究中心将严格按照顺序依次分配随机代码。随机代码将以区组的方式由 SAS 生成,以确保两个治疗组之间接近平衡(1:1)。本次研究计划的随机化患者人数约为 1060 例。随机分组完成后,在试验过程中不允许交换分组组别。 第 1 次访视,由研究者依据受试者入组顺序,向配液专员提供受试者随机代码,配液专员依据随机代码,确定受试者的唯一治疗药盒识别码(ID),用于患者的第 1 次访视药品供应。患者需在随机化后,股动脉穿刺前尽早实现研究药物的首次给药。该随机号将记录在入组筛选表及 CRF上。

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

A center-stratified block randomization method will be adopted with centralized control of subject allocation by the clinical trial coordination center. Eligible subjects at each participating site will be assigned randomization codes sequentially according to their enrollment order. The randomization codes will be generated in blocks using SAS software to ensure approximate balance between the two treatment groups (1:1 ratio). A total of approximately 1060 subjects are planned for randomization in this study. Once randomized subjects are not allowed to switch between groups during the study. At the first visit the investigator will provide the randomization code of the enrolled subject to the preparation personnel who will determine the subjects unique drug kit identification number (ID) based on the code. This ID will be used to supply the investigational product for the subjects first visit. The investigational product should be administered as early as possible after randomization and before femoral artery puncture. The randomization code will be recorded in both the enrollment screening form and the Case Report Form (CRF).

盲法:

本研究为双盲试验。研究用药和安慰剂外观、颜色、标签完全一致,受试者、研究人员、结果评估者均对分组未知。所有疗效评估均由盲态评估者完成。 为了保证盲法的执行,参与随机化编码或有可能接触盲底的人员、药物管理的医生或护士、药物配制与输液操作人员不应参与注射过程、受试者的选择、疗效的评价和安全性的评估等活动,参与受试者筛选、疗效和安全性评估的相关人员不能接触配液与用药过程,以免引入偏倚。试验药物由第三方负责生产、包装,要求试验药物和安慰剂在外观、形状、颜色及内容物的色泽方面基本一致,并进行检验。此外,为保证盲法,两组的药物包装(使用避光输液器、输液袋)、批号均完全相同,包装批号统一标注。每盒药品上将标有唯一的药品 ID 编号,这一编号将用于指定患者所接受的治疗,但不会向研究者或患者提示治疗分配情况。研究实施期间,除了药物提供厂家的供应链、研究管理部门和患者安全部门之外,各个研究执行小组的成员、研究中心人员以及数据处理人员都不能查看随机化方案。DSMB 会定期审查疗效和安全性数据,包括不良事件(adverse event,AE)的发生率和安全性评估结果,以确保参加研究的患者的安全。研究期间,由独立的统计师向 DSMB 提供基本的安全性和疗效数据。

Blinding:

This is a double-blind trial. Study drugs and placebos are indistinguishable in appearance color and labeling. Participants investigators and outcome assessors are blinded to the treatment allocation. All efficacy assessments are conducted by blinded evaluators. To ensure proper implementation of the blinding personnel involved in randomization coding or those who may have access to the randomization listsuch as drug management physicians or nurses drug preparation and infusion staffshall not participate in the injection process subject selection efficacy assessment or safety evaluation. Personnel responsible for screening efficacy and safety assessments must not have access to the drug preparation or administration process so as to avoid introducing bias. The investigational product and placebo will be manufactured and packaged by a third party. Both are required to be identical in appearance form color and content characteristics and will be tested accordingly. To maintain blinding the packaging (including light-protective infusion sets and bags) and batch numbers for both groups will be completely identical with uniform labeling of batch codes. Each drug box will be labeled with a unique drug ID number which will determine the treatment assigned to the subject without revealing the treatment allocation to investigators or subjects. During the study only the drug suppliers logistics chain the study management team and patient safety departments will have access to the randomization scheme. Members of the study execution teams site personnel and data processing staff are not permitted to access the allocation information. The Data Safety Monitoring Board (DSMB) will conduct periodic reviews of efficacy and safety data including the incidence of adverse events (AEs) and safety evaluations to ensure the protection of study participants. An independent statistician will provide the DSMB with basic safety and efficacy data throughout the study.

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:

在试验期间,研究者填写病例报告表(CRF),并将临床数据整合到电子数据采集系统(EDC)中。通过计算机化的逻辑和/或一致性检查进行质量控制,系统性地检测错误或遗漏。所有数据由临床监查员审核后提交数据管理员进行数据管理。

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

During the trial investigators will complete the Case Report Forms (CRFs) and enter clinical data into the Electronic Data Capture (EDC) system. Quality control will be performed through computerized logic and/or consistency checks to systematically identify errors or omissions. All data will be reviewed by clinical monitors and then submitted to data managers for centralized data management.
