Participant Protection
These three types of qualifications show that an investigator can take responsibility for a trial.
What are education, training and experience.
This electronic history lets a reviewer trace changes to trial data while retaining the original entry.
What is an audit trail?
Preserve the record of changes and the original entry so a reviewer can trace the data history.
This approach scales trial controls to the importance of the risks rather than applying the same effort everywhere.
What is a risk-proportionate approach?
Focus oversight on risks that matter to participant protection and the reliability of results.
After delegating trial activities at a site, this person retains ultimate responsibilty and appropriate oversight
Who is the investigator.
The original paper record is destroyed after scanning. The scan is acceptable only if it is verified to preserve this full set of qualities.
What are the same information, context, content and structure as the original?
A certified copy is verified—by dated signature or a validated process—to preserve the original record’s information, context, content and structure.
A sponsor transfers trial duties to a CRO. The contract names the CRO, but this accountability does not transfer.
What is the sponsor’s ultimate responsibility for trial quality and integrity?
The sponsor should define transferred activities, select qualified parties and maintain documented oversight. Transfer of duties does not eliminate sponsor accountability.
A participant signs a revised consent form after new risk information. The signature is present, but the file contains no note that the change was discussed. This missing evidence shows consent was an ongoing process—not just a form.
What is documentation of the re-consent discussion?
Record that the new information was explained, questions were answered and the participant chose to continue. The signature alone does not describe the consent process.
After an eTMF migration, every document opens in the new system. That alone is not enough; inspectors also expect proof that these elements survived and remain retrievable.
What are completeness, metadata, audit trails and readability?
Migration controls should preserve record meaning and history, with reconciliation or QC evidence and continued access throughout the retention period.
A vendor dashboard is green every month, but the sponsor cannot show review of missed milestones or escalation of recurring issues. This oversight evidence is missing.
What are documented sponsor review, escalation and follow-up?
Dashboards alone do not demonstrate oversight. Retain evidence that the sponsor reviewed performance, challenged issues, escalated when needed and tracked resolution.
An adult participant cannot read. The form bears the participant’s mark, but nobody independent attended the consent discussion. This missing safeguard is expected when the participant or representative cannot read.
Who is an impartial witness?
The impartial witness attends the entire consent discussion and signs and dates the form to attest that the information was accurately explained, understood and freely accepted.
A data query leads to a correction, but the original value is overwritten and only the corrected result remains. These traceability elements are missing.
What are completeness, metadata, audit trails and readability?
Migration controls should preserve record meaning and history, with reconciliation or QC evidence and continued access throughout the retention period.
Monitoring finds repeated deviations at one site, but no immediate serious harm. A blanket increase in visits everywhere is less appropriate than this targeted response.
What are root-cause analysis and risk-based CAPA with intensified oversight?
Assess impact, address causes, document corrective and preventive actions, and adjust monitoring or escalation in proportion to the risk.
A site re-consents participants with an older approved form after a revised form with important new risk information became applicable. No participant was harmed. This inspection issue still remains.
What is failure to use the current approved consent information and re-consent promptly?
Control consent-form versions and effective dates, communicate important new information promptly, and document re-consent using the applicable approved form.
A data query leads to a correction, but the original value is overwritten and only the corrected result remains. These traceability elements are missing.
What are the original value, who changed it, when and why?
A correction should not obscure the original entry. The record should identify the person making the change, its timing and the reason when required.
Central monitoring finds the same deviation trend across several sites after local retraining. Repeating site-by-site training is less appropriate than this broader response.
What are trial-level impact assessment, root-cause analysis and effectiveness-checked CAPA?
Treat the pattern as a systemic signal: assess trial-wide impact, address the underlying cause, implement proportionate action and verify that it works.
