Trial master files (TMFs) are central repositories for essential clinical trial documents and data that support data integrity and quality. TMFs help studies comply with GCP guidelines and regulatory requirements by providing a complete and accurate record of all trial activities. TMFs include audit trails that track document access and changes, supporting data traceability and version control.

Electronic TMF (eTMF) systems provide centralized storage, access, and management of clinical trial documents and data that are easier to search and retrieve than paper-based systems. eTMF systems can integrate with other clinical trial tools, such as electronic data capture (EDC) systems, for a cohesive and efficient clinical data ecosystem.

 

ALCOA-CCEA Principles In Clinical Data Management

ALCOA+ principles represent the industry’s high standards for CDM. A CDM strategy must meet these standards to comply with regulatory authorities:

• Attributable: All data collected in a clinical trial must be fully traceable to their source via a robust audit trail that lists who collected the data, where, and when, which follows the FDA's 21 CFR Part 11 guidelines.
• Legible: Data must be readable by humans and kept in a durable, accessible medium.
• Contemporaneous: Data are recorded as soon as they are collected. Every data collection activity, including changes to the original record, is tracked and time stamped.
• Original: All original records are preserved to ensure data integrity. Electronic data systems must maintain the raw data and prevent it from being modified.
• Accurate: Data must be thorough, reliable, and free of errors. Electronic data systems should include accuracy checks and validation controls.

 

In addition to the basic ALCOA principles described above, CDM also includes:

• Complete: CDM systems must ensure that the data contain all details with nothing deleted from the records and include a thorough audit trail.
• Consistent: To provide consistency, data should be organized chronologically and time-stamped.
• Enduring: Any materials used to collect and store data, including digital systems, must be durable to allow future access and include redundant backup systems.
• Available: Data must be accessible and retrievable for review whenever necessary.
