随机方法(请说明由何人用什么方法产生随机序列): |
试验所需,所有受试者将有三种号码,即筛选号、随机号和药物包装号。 每位受试者先分配筛选号,筛选号由各个临床试验单位确定,由“S”+5位数字组成,前2位数字为中心号,后3位数字为该中心筛选顺序号。例如:03中心筛选的第6位受试者,其筛选号即为S03006。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
For trial requirements, all subjects will be assigned three identification numbers: a screening number, a randomization number, and a drug package number. Each subject will first be assigned a screening number, which is determined by individual clinical trial sites. The screening number consists of "S" followed by 5 digits, where the first 2 digits represent the center number and the last 3 digits represent the sequential screening number at that center. For example, the 6th subject screened at center 03 will have the screening number S03006. |

Blinding: |
This trial adopts a double-blind design. The on-site drug blinding process will involve personnel from the randomization unit and sponsor-affiliated staff unrelated to this trial. Using SAS software (version 9.4 or higher), drug package numbers and verification codes will be generated along with their corresponding treatment group assignments. These drug package numbers and verification codes will then be entered (or affixed) onto the labels of the corresponding drugs (investigational drug or control drug). The entire blinding process will be documented in a blinding record for preservation. |

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: |
本次试验采用电子化数据管理,使用电子数据采集(EDC)系统收集临床试验数据。以下列出数据管理主要流程,其他详见数据管理计划(DMP)。DMP 作为数据管理的指导性文件由数据管理人员(DM)撰写,申办方批准,数据管理工作将根据DMP 的约定进行。 1、EDC 数据管理 电子病例报告表(eCRF):数据管理人员根据试验方案设计构建,并根据数据核查计划(DVP)设置逻辑核查,通过测试并获申办方批准后发布使用。 数据录入:eCRF 数据来源于原始记录,由数据录入人员根据eCRF 填写说明,将受试者访视数据及时录入EDC。源数据现场核查(SDV):监查员进行eCRF 数据与源数据的一致性核对,有问题可发疑问。 数据疑问和解答:疑问来源于EDC 逻辑核查的系统疑问,监查员、数据管理员、医学专员等人工疑问,研究者需及时解答疑问。数据管理员、监查员和医学专员进行疑问批复,必要时可再次发出疑问,直至数据“清洁”。 研究者签名:数据录入完成并经SDV 后,研究者进行电子签名审核确认。签名后的如有数据修订,需重新签名。 数据库锁定:由主要研究者、申办者、统计分析人员和数据管理人员共同签署数据库锁定声明后,数据管理人员进行数据库锁定。 数据集提交:数据管理员向统计人员提交数据库。 eCRF 存档:每个受试者的eCRF 生成PDF 电子文档保存。 EDC 关闭:统计分析完成后,数据管理员关闭数据库。 2、外部数据传输 签署外部数据传输协议,根据DMP 进行外部数据管理。 3、医学编码 不良事件采用MedDRA(27.1 或以上版本)字典进行编码,合并用药采用WHO ATC进行编码。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This trial employs electronic data management, utilizing an Electronic Data Capture (EDC) system for collecting clinical trial data. The main data management processes are outlined below, with additional details specified in the Data Management Plan (DMP). The DMP serves as the guiding document for data management, prepared by Data Management (DM) personnel and approved by the sponsor. All data management activities will be conducted in accordance with the DMP provisions. 1. EDC Data Management Electronic Case Report Form (eCRF): Designed by data management personnel based on the trial protocol, with logical checks configured according to the Data Validation Plan (DVP). The eCRF will be released for use after testing and sponsor approval. Data Entry: eCRF data originates from source documents. Data entry personnel will promptly input subject visit data into the EDC following eCRF completion instructions. Source Data Verification (SDV): Monitors will verify consistency between eCRF data and source documents, raising queries if discrepancies are identified. Data Queries and Resolutions: Queries may originate from EDC system-generated logical checks or manual queries raised by monitors, data managers, or medical specialists. Investigators must resolve queries promptly. Data managers, monitors, and medical specialists will review query resolutions and may reissue queries until data are "clean." Investigator Sign-off: After data entry completion and SDV, investigators will electronically sign to confirm review. Any post-signature data modifications require re-signature. Database Lock: Following joint approval via a signed database lock declaration by the principal investigator, sponsor, statistician, and data manager, the data manager will lock the database. Dataset Submission: The data manager will submit the database to the statistical team. eCRF Archiving: Each subject's eCRF will be saved as a PDF electronic document. EDC Closure: Upon completion of statistical analysis, the data manager will close the database. 2. External Data Transfer External data transfer agreements will be executed, with external data managed per the DMP. 3. Medical Coding Adverse events will be coded using the MedDRA dictionary (version 27.1 or higher). Concomitant medications will be coded using WHO ATC classification. |
