What is it? Why is it important?

Once the study is finalised, a study site can still be:

  • Audited by the SP-INV
  • Inspected by Swissmedic
  • Reviewed by EC

Inspections can occur even after the study has ended and all its documents have been archived.

Reasons for a post-audit or a post-inspection include:

  • A re-evaluation of the study data (e.g. open questions remain, suspicion of study misconduct, IMP registration)
  • A re-evaluation of the study safety data (e.g. needed for the Clinical Study Report (CSR) or additional requests from EC and/or Swissmedic)

What do I need to do?

As a SP-INV and Site-INV:

  • Ensure to archive the study so that all documents are readily available for a post-inspection or post-audit
  • In the event of a post-inspection or post-audit, follow the same procedures as would be expected during an audit or inspection during study conduct

For more information refer to QM and Risks in this Study Guide.
