For how long should essential trial documents be retained after trial completion?

The correct retention period for essential trial documents after trial completion is at least two years after the conclusion of the study. This timeframe is established to ensure that any necessary documentation related to the study is available for review, in case of regulatory inquiries or audits. Retaining trial documents for this period is crucial to uphold the integrity of the research process, as it allows for accountability and transparency in clinical research.

Additionally, there may be specific requirements dictated by regulatory bodies or institutional policies that emphasize the necessity of holding onto essential documents for this duration to protect the rights and safety of study participants and ensure that investigators can respond to any concerns that may arise post-study. This practice helps maintain a comprehensive record of the research that can support further research endeavors and contribute to the collective knowledge in the field.
