Rethinking Clinical Trial Data Retention: Moving Towards Centralized Storage
In clinical research, Sites are traditionally required to retain trial data for 15 to 20 years or longer, despite not owning it. This expectation, rooted in historical practices, poses significant operational and logistical challenges as Principal Investigators (PIs) retire, practices close, or data storage systems become obsolete.
The practice of data retention by Sites began when paper-based documentation was the norm.
Regulatory bodies like the FDA, EMA, and MHRA mandated that data be accessible for audits, legal claims, and post-market surveillance.
Sites became the natural custodians, and despite the shift to digital systems, this expectation remained unchanged.
To overcome these challenges, the industry should transition to centralized, Sponsor-controlled data repositories. This modernized approach offers:
Enhanced Security: Centralized storage can implement robust cybersecurity measures.
Regulatory Compliance: Ensures easy access to data for audits and inspections. Operational Continuity: Reduces dependency on Sites and ensures seamless data availability. Standardized Access: Simplifies data management across multiple Sites.

Why Do Sites Retain Trial Data?

Key Challenges of Site-Based Data Retention
Data Loss Risks: Long-term storage increases the risk of data loss or corruption.
PI Turnover: When PIs retire or Sites shut down, access to data becomes complicated.
Cybersecurity Threats: Sites may lack robust cybersecurity infrastructure, increasing vulnerability to breaches.
Operational Inefficiencies: Sponsors, who ultimately own the data, face challenges in accessing it across multiple Sites.

Transitioning to centralized data storage requires clear contractual agreements and well-defined data handoff protocols. Sponsors must also work with regulatory authorities to align guidelines with modern storage practices. By shifting data custody to Sponsors, the industry can reduce operational risks, streamline data access, and ensure long-term compliance. It’s time for a paradigm shift — one that enhances data integrity, security, and efficiency in clinical research.
