Regulatory authorities require sponsors to maintain proper oversight of the Trial Master File (TMF), yet many companies struggle with last-minute preparation when inspection notices arrive. This article emphasizes the importance of integrating TMF management into routine processes to ensure continuous inspection readiness.

A whole-system approach is key, focusing on planning, preparation, and practice. Effective TMF management goes beyond document storage—it requires stakeholder engagement, compliance with regulatory expectations, and proactive risk-based quality reviews. Inspectors assess oversight rigor, necessitating a structured approach to defining and documenting risk-based reviews. Key considerations include selecting TMF segments for review, tracking document completeness, and ensuring transparency in oversight.

Access control is another crucial factor, as inspectors scrutinize who has TMF access, especially to unblinded documents. Failure to revoke outdated permissions can raise compliance concerns. Additionally, thorough documentation reviews should be routine, focusing on completeness, timeliness, compliance with processes, and data integrity.

To ensure readiness, sponsors should implement an inspection plan, conduct risk assessments, develop remediation strategies, and perform mock inspections. These steps help identify gaps, streamline document management, and prepare teams for regulatory scrutiny.

Ultimately, a proactive approach to TMF oversight reduces the risk of negative findings, ensuring a well-maintained TMF that supports regulatory compliance and long-term study success.
