研究目的:

主要研究目的是在SGLT2i联合二甲双胍治疗基础上仍无法有效控制血糖的2型糖尿病患者中评价加用考格列汀较二甲双胍剂量递增治疗24周后糖化血红蛋白(HbA1c)水平相对基线的变化。 次要研究目的是在SGLT2i联合二甲双胍治疗基础上仍无法有效控制血糖的2型糖尿病患者中评价加用考格列汀较二甲双胍剂量递增治疗24周后下列指标的变化(对于需作前后对比评价的指标,基础治疗期对比的水平为基线): ? 治疗24周后HbA1c<7.0%和<6.5%的受试者比例; ? 治疗12周及24周后餐后2小时血葡萄糖(2h-PPG)和空腹血葡萄糖(FPG)相对基线的变化; ? 治疗12周后HbA1c水平相对基线的变化; ? 治疗24周后体重、空腹C肽、胰岛素敏感性、β细胞功能相对基线的变化; ? 因高血糖需挽救治疗而退出的受试者比例; ? 加用考格列汀三药治疗后的安全性。  

Objectives of Study:

Primary Research Objective: The primary objective of this study is to evaluate the change in glycated hemoglobin (HbA1c) levels of adding cofrogliptin compared to escalation of metformin dose after 24 weeks in type 2 diabetes patients who have failed to achieve adequate glycemic control despite receiving combination therapy with SGLT2i and metformin. Secondary Research Objectives: The secondary objectives of this study are to evaluate the changes in the following parameters (for indicators requiring pre-post comparison, the baseline level during the baseline treatment period is used for comparison):of adding cofrogliptin compared to escalation of metformin dose after 24 weeks in type 2 diabetes patients who have failed to achieve adequate glycemic control despite receiving combination therapy with SGLT2i and metformin: 1) The proportion of subjects with HbA1c < 7.0% and < 6.5% after 24 weeks of treatment. 2) Changes in 2-hour postprandial plasma glucose (2h-PPG) and fasting plasma glucose (FPG) from baseline at 12 and 24 weeks of treatment. 3) Change in HbA1c levels from baseline after 12 weeks of treatment. 4) Changes in body weight, fasting C-peptide, insulin sensitivity, and β-cell function from baseline after 24 weeks of treatment. 5) The proportion of subjects who withdrew due to the need for rescue therapy for hyperglycemia. 6) The safety profile of triple therapy with cofrogliptin.

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:

数据管理 本研究数据管理由赞助方委托的数据管理团队负责,以确保临床试验数据的真实性、完整性、私密性和可溯源性。 数据录入 本研究将采用太美医疗科技公司搭建的电子数据采集(Electronic Data Capture,EDC)系统进行数据收集,使用电子版病例收集表(eCRF)存储和传递受试者信息,eCRF必须由研究者审核,电子签名并且注明日期。所有eCRF的填写和修改须由研究者或经授权的研究人员完成,并核对其准确性。研究数据录入eCRF时,系统将会通过登录用户的ID,自动添加数据录入者身份。研究中心启动或数据录入前,将对研究者和授权的研究人员进行适当培训。 数据录入应于访视期间或之后尽快完成,并及时更新,以保证其能够反映受试者的最新动态。研究者须审核数据,以确保录入到eCRF中的所有数据的准确性。研究者通过电子签名证明其已对数据进行审核,且确认记录的数据的准确性。 若无特殊说明,eCRF将只作为收集数据的表格,并不能作为原始资料。CRA将审核eCRF中的每个数据点,并对eCRF和源数据进行对比以确保数据的完整性和一致性。 所有数据的输入、更正和修改都将由研究者或其授权人员负责,而监查员无此权限。eCRF中的数据提交至数据服务器,对数据的任何更改均将记录于稽查痕迹中,即更改原因、操作者姓名、修改时间和日期将被记录。将预先确定研究中心负责数据输入的工作人员的角色和权限。若有数据质疑,CRA或数据管理人员将在EDC中发出质疑,并由研究中心工作人员负责答疑。EDC系统将记录质疑的稽查轨迹,包括研究者或其他授权人姓名、时间和日期。 研究者须为每位参加研究的受试者提交完整的eCRF,包括筛选失败的受试者数据。

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

Data Management The management of study data is entrusted to a data management team commissioned by the sponsor to ensure the authenticity, integrity, confidentiality, and traceability of clinical trial data. Data Entry For data collection, this study will utilize an Electronic Data Capture (EDC) system developed by TaiMed Medical Technology Company, employing Electronic Case Report Forms (eCRFs) to store and transmit subject information. The eCRFs must be reviewed, electronically signed, and dated by the investigators. All filling and modifications to the eCRFs must be completed by investigators or authorized research staff and verified for accuracy. When research data is entered into the eCRFs, the system automatically logs the identity of the data entrant through the user's ID. Appropriate training will be provided to investigators and authorized research staff prior to the study center's initiation or data entry. Data entry should be completed as soon as possible during or after the visit and updated promptly to reflect the latest status of the subjects. Investigators must review the data to ensure the accuracy of all data entered into the eCRFs. Investigators certify their review and confirm the accuracy of recorded data through electronic signatures. Unless otherwise specified, the eCRFs serve solely as data collection forms and do not constitute original source documents. The Clinical Research Associate (CRA) will review each data point in the eCRFs and compare them to source data to ensure completeness and consistency. The responsibility for all data entry, corrections, and modifications lies solely with the investigators or their authorized personnel; monitors do not have access to these permissions. Data submitted from the eCRFs to the data server is tracked through audit trails, where reasons for changes, operator names, modification times, and dates are recorded. Roles and permissions for data entry staff at the research center will be predefined. In case of data queries, the CRA or data management personnel will raise questions in the EDC, and the research center staff will be responsible for answering them. The EDC system will record the audit trail for queries, including the names, times, and dates of the investigators or other authorized individuals. Investigators must submit complete eCRFs for every subject participating in the study, including data from subjects who fail screening.
