When using overseas clinical trial data for IVD (In Vitro Diagnostic) products, attention should be paid to the following aspects:

Ⅰ. Data Quality and Integrity

Ensuring Data Accuracy: Utilize validated data collection tools and methods, such as Electronic Data Capture (EDC) systems. Implement a double-entry and verification mechanism to reduce human entry errors. Conduct regular data consistency checks and logical checks to identify and correct abnormal values and errors.

Ensuring Data Integrity: Maintain detailed records and traceability from trial design to data collection, processing, and analysis. Ensure that all relevant data is collected completely without omissions.

Ⅱ. Data Compliance

Adhering to Relevant Regulations and Guidelines: Understand and comply with the regulations and guidelines for in vitro diagnostic reagents in the target market (e.g., the European Union, the United States, etc.). For instance, the IVDR (In Vitro Diagnostic Medical Devices Regulation) of the European Union has specific requirements for clinical trial data.

Ethical Review: Ensure that the management process of clinical trial data complies with the requirements of the Ethics Committee (REC) to protect the rights and interests of subjects.

Ⅲ. Sample Size and Representativeness

Meeting Sample Size Requirements: Ensure that the total sample size of clinical trials meets the minimum requirements according to the regulations of the target market. For example, the IVDR regulations of the European Union have different sample size requirements for different types of in vitro diagnostic reagents.

Ensuring Sample Representativeness: The samples should represent the patient population in the target market, including different ages, genders, races, etc. Consider factors such as the severity and course of the disease to ensure sample diversity. Data Security and Privacy Protection

Protecting Subject Privacy: Anonymize personal identity information during data collection and storage. Restrict data access permissions to only authorized personnel.

Ensuring Data Security: Use secure data storage and transmission methods to prevent data breaches and unauthorized access. Regularly perform data backup and recovery tests to ensure data reliability and recoverability.

Ⅳ. Data Analysis and Interpretation

Developing a Statistical Analysis Plan: Develop a detailed statistical analysis plan before the trial begins, describing the data analysis methods and steps. Use validated data analysis tools and software for analysis. 

Providing Appropriate Data Interpretation: Reasonably interpret and discuss the data analysis results. Explain the clinical significance of the data and its impact on the safety and effectiveness of the product.

Ⅴ. Audit and Regulation

Accepting Audits: Conduct regular internal and external audits (such as audits by regulatory authorities or independent third parties) to ensure the compliance and effectiveness of the data management process.

Cooperating with Regulatory Reviews: Cooperate with the regulatory authorities in the target market for data review and supervision. Provide necessary data and information, and explain the source and meaning of the data.

In summary, when using overseas clinical trial data for IVD products, it is necessary to ensure data quality and integrity, comply with relevant regulations and guidelines, meet sample size and representativeness requirements, protect data security and privacy, develop appropriate statistical analysis plans and provide appropriate data interpretation, as well as accept audits and cooperate with regulatory reviews. These measures will help ensure the validity and reliability of overseas clinical trial data, providing strong support for product registration and market launch.
