研究设计:

巢式病例-对照研究 

Study design:

Nested case-control study 

研究目的:

主要目的:比较使用古塞奇尤单抗治疗克罗恩病患者失应答组、应答组患者在基线、失应答(原发性失应答和继发性失应答)和应答时(T0, T1, T2)?的血清、粪便及肠黏膜组织生物标志物差异,揭示药物失应答的潜在机制。 次要目的:1)分析两组患者治疗过程中药物浓度、抗药物抗体及细胞因子谱的动态变化差异。 2)探索与继发性失应答相关的临床预测因素。  

Objectives of Study:

Main objective: To compare the differences in serum, fecal, and intestinal mucosal biomarkers between the non responsive group and the responsive group of Crohn's disease patients treated with gusetuximab at baseline, non responsive (primary and secondary), and response time (T0, T1, T2), and to reveal the potential mechanism of drug non response. Secondary objective: 1) Analyze the dynamic differences in drug concentration, anti drug antibodies, and cytokine profiles between two groups of patients during treatment. 2) Explore clinical predictive factors associated with secondary loss of response.

Exclusion criteria:

1) Relapse is caused by clear infection (such as Clostridium difficile, CMV), use of nonsteroidal anti-inflammatory drugs, or simple obstructive symptoms caused by intestinal stenosis. 2) Plan to use other systemic immunosuppressants or biologics in combination during re induction therapy (allowing for stable doses of aminosalicylic acid preparations). 3) It has been confirmed in the past that there is no response or severe allergic reaction to gusetuximab. 4) Pregnant or lactating women(or planning for pregnancy). 5) There are serious extraintestinal manifestations, active malignant tumors or serious infections (such as herpes virus, hepatitis B, hepatitis, tuberculosis).

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:

一是根据研究人员所撰写的研究方案,并遵循伦理审查委员会的要求,收集参与该项临床项目研究的患者信息,包括但不限于患者的基本信息,病史、相关检验结果、治疗过程、随访结果、应答状况等,如实记录标本收录时间,随访时间等,并形成一份完整的病例记录表,对其进行分类对比研究来验证研究猜想; 二是使用SAS、PASS等统计软件,对收集到的数据进行录入、分类、核实、整理等操作,提高数据管理效率,降低误差率。

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

First, based on the research protocol drafted by the researchers and in accordance with the requirements of the ethics review committee, collect patient information for the clinical study project, including but not limited to basic patient data, medical history, relevant test results, treatment process, follow-up results, and response status. Accurately record specimen collection times, follow-up periods, and other details, then compile a comprehensive case record form for comparative classification research to validate the study hypothesis; The second is to use statistical software such as SAS and PASS to input, classify, verify, and organize the collected data, thereby improving data management efficiency and reducing error rates.
