What is a typical duration for trial-record retention after completion?

• A. 10 years after completion.
• B. 1 year after completion.
• C. Often 2–5 years after completion, varying by jurisdiction.
• D. Indefinitely.

Answer: (C)

Retention of trial records is governed by regulatory rules and varies by jurisdiction. In practice, the typical window is two to five years after the trial is completed, with the exact length depending on local laws and the product involved. This range balances regulatory needs—to allow audits, inspections, and safety monitoring—even after the study has ended—with practical considerations of data management. Some guidelines specify keeping essential documents at least two years after the last regulatory approval in a region where the trial occurred, or after completion, whichever is later, and to extend that period if local requirements demand it. Longer retention may be required for certain products, higher-risk studies, or privacy laws, but two to five years is the common expectation. A shorter period like one year is generally insufficient for regulatory oversight, while a much longer period such as ten years or indefinite retention goes beyond typical practice unless specifically mandated.
