Trial-record retention is about how long essential trial documents must be kept after a study ends. In practice, a typical window is two to five years after completion, with the exact length varying by jurisdiction and product status. This range ensures records are available for regulatory audits, safety follow-up, and any potential investigations or inquiries that could arise after the trial. Shorter periods like six months or one year usually don’t cover the time regulators or sponsors may need to address post-trial questions, while keeping records indefinitely isn’t the norm under most regulatory frameworks, though certain circumstances can require longer retention. So, two to five years after completion is the common, practically safe span.
