研究目的:

通过多中心随机对照研究,系统验证基于耐药基因检测的精准治疗方案相较于经验性治疗在首次根除率方面的优势,为解决我国Hp防治面临的“高感染率-低根除率”困境提供循证依据。研究成果将推动分子诊断技术向基层医疗机构下沉,为建立“诊断-治疗-监测”一体化防控体系奠定基础,对遏制细菌耐药传播、降低胃癌发病风险具有重大公共卫生价值。  

Objectives of Study:

Through a multicenter randomized controlled trial, this study systematically validates the superiority of a precision treatment plan based on drug resistance gene testing over empirical therapy in terms of the initial eradication rate. It provides evidence-based support for addressing the challenge of "high infection rates but low eradication rates" in the prevention and treatment of Helicobacter pylori (Hp) in China. The research findings will facilitate the integration of molecular diagnostic technologies into primary healthcare institutions, laying the foundation for establishing an integrated "diagnosis-treatment-monitoring" prevention and control system. This holds significant public health value for curbing the spread of bacterial drug resistance and reducing the risk of gastric cancer incidence.

Description for medicine or protocol of treatment in detail:

Guidance medication group: Complete capsule sampling line examination within 1 day after enrollment to detect Helicobacter pylori resistance genes in gastric contents. The test results are expected to be provided within 3-5 working days. Based on the testing report, select an individualized eradication plan that matches the drug resistance spectrum from the recommended standard treatment plans in the guidelines. Clarithromycin sensitive strains (including cases of simultaneous sensitivity to clarithromycin and levofloxacin): EBAC regimen (esomeprazole 20mg+bismuth potassium citrate 220mg+amoxicillin 1000mg+clarithromycin 500mg, twice a day) for 14 days; Levofloxacin sensitive strain (clarithromycin resistant): EBAL regimen (esomeprazole 20mg+bismuth potassium citrate 220mg+amoxicillin 1000mg, twice daily+levofloxacin 500mg, once daily) for 14 days; Metronidazole sensitive strains: EBAM regimen (esomeprazole 20mg+bismuth potassium citrate 220mg+amoxicillin 1000mg+metronidazole 400mg twice a day) for 14 days; Multidrug resistant strains: (esomeprazole 20mg+bismuth potassium citrate 220mg+amoxicillin 1000mg+furazolidone 0.1g, twice a day) or (esomeprazole 20mg+bismuth potassium citrate 220mg+amoxicillin 1000mg, twice a day+tetracycline 500mg, four times a day), for a period of 14 days. Experience based treatment group (standard quadruple protocol, recommended by guidelines): All patients received a 14 day empirical standard anti-H. pylori eradication treatment. Based on the patient's past medication history and commonly used clinical protocols, choose one of the following for treatment: EBAC: Esomeprazole 20 mg BID+Bismuth Potassium Citrate 220 mg BID+Amoxicillin 1000 mg BID+Clarithromycin 500 mg BID; EBAL: Esomeprazole 20 mg BID+Bismuth Potassium Citrate 220 mg BID+Amoxicillin 1000 mg BID+Levofloxacin 500 mg QD; EBAM: Esomeprazole 20 mg BID+Bismuth Potassium Citrate 220 mg BID+Amoxicillin 1000 mg BID+Metronidazole 400 mg TID-QID; Medication instructions (applicable to both groups): PPI (such as Nexen 20 mg BID) or P-CAB (such as Tegolasone/Vorosuvastatin 20 mg BID) can be selected for PPI/P-CAB used in the study; Bismuth agents can be chosen from bismuth potassium citrate or pectin bismuth agents, both of which are used at nationally approved doses; Clarithromycin can be chosen as either clarithromycin or clarithromycin, depending on the supply situation of each center pharmacy.

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.数据采集方法:?? 本研究采用??电子化数据采集?? 系统进行数据管理。所有受试者的原始数据将首先记录于??纸质的病例报告表(CRF)?? 上。随后,由经授权的研究人员将数据录入到??电子数据采集(EDC)?? 系统中。 ??病例报告表(CRF):?? 为每位受试者设计专用的CRF,用于在访视点实时、准确地记录所有方案要求的数据,包括人口统计学资料、疗效指标(如幽门螺杆菌根除率的13C-尿素呼气试验结果)、安全性指标(不良事件)、合并用药等。CRF上的数据作为原始记录。 ??电子数据采集(EDC)系统:?? 本研究将使用基于互联网的EDC系统进行数据管理,例如 ??ResMan临床试验公共管理平台??(或其他您正在使用的系统名称,如Clinfla, Rave等)。该系统提供数据录入、查询、验证和存储功能。 ??2. 数据管理流程:?? 为确保数据的准确性,将执行以下严格的数据管理流程: ??双次录入:?? 关键数据(如主要疗效终点)将采用双人双次录入方式,并由系统进行一致性检验。 ??逻辑核查:?? 在EDC系统中预设逻辑核查规则,自动识别数据中的异常值、缺失值或逻辑错误(如访视日期不符等)。 ??数据质询:?? 数据管理员或监查员会通过EDC系统向研究中心发出数据质询。研究者需根据原始病历等源文件对质询进行回复和更正,所有质询和修改痕迹将在系统中保留记录。 ??源数据验证(SDV):?? 临床研究监查员将定期到研究中心,核对EDC系统中的数据与CRF及原始医疗记录(源数据)的一致性。 ??数据库锁定:?? 在所有数据清理工作完成后,经主要研究者、申办方和统计学家共同审核并批准后,对最终的数据库进行锁定。锁库后,任何数据修改都需经过严格的变更控制流程。 ??3. 保密性与安全性:?? 所有受试者数据将进行匿名化处理,用唯一的受试者识别代码代替个人信息。EDC系统通过角色权限管理、登录密码保护和数据加密传输等技术,确保数据的保密性和安全。

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

1. Data Collection Methods:?? This study will utilize an ??electronic data capture system?? for data management. All original subject data will be initially recorded on ??paper-based Case Report Forms??. Subsequently, authorized research personnel will enter the data into an ??Electronic Data Capture system??. ??Case Report Form (CRF):?? A dedicated CRF will be designed for each subject to accurately record all protocol-required data at each visit point, including demographic information, efficacy endpoints (e.g., H. pylorieradication results from the 13C-urea breath test), safety indicators (adverse events), and concomitant medications. Data on the CRF serves as the original record. ??Electronic Data Capture (EDC) System:?? This study will use an internet-based EDC system for data management, such as the ??ResMan Clinical Trial Public Management Platform?? (or another system name, e.g., Clinfla, Rave, etc.). This system provides functions for data entry, query, validation, and storage. ??2. Data Management Processes:?? To ensure data accuracy, the following rigorous data management processes will be implemented: ??Double Data Entry:?? Key data (e.g., primary efficacy endpoints) will undergo double data entry by two different individuals, with consistency checks performed by the system. ??Logical Checks:?? Pre-defined logical check rules will be configured within the EDC system to automatically identify outliers, missing values, or logical errors (e.g., inconsistent visit dates). ??Data Query Management:?? Data managers or monitors will issue data queries to the research sites via the EDC system. Investigators must respond to and correct data based on source documents (e.g., original medical records). All queries and modifications will be tracked within the system. ??Source Data Verification (SDV):?? Clinical research monitors will periodically visit the research sites to verify the consistency between the data in the EDC system, the CRF, and the original medical records (source data). ??Database Locking:?? After all data cleaning activities are completed, the final database will be locked following joint review and approval by the Principal Investigator, the Sponsor, and the Statistician. Any post-lock changes to the data would require a strict change control process. ??3. Confidentiality and Security:?? All subject data will be anonymized, with personal identifiers replaced by unique subject identification codes. The EDC system employs role-based access control, login password protection, and data encryption during transmission to ensure data confidentiality and security.
