Purpose
The purpose of this SOP is to establish procedures for making corrections to clinical trial documents, managing document versions, and maintaining
Scope
This SOP applies to investigators, study coordinators, CRAs, data managers, sponsors, and CROs involved in clinical trial documentation. It includes paper and electronic documents stored in Investigator Site Files (ISFs), Trial Master Files (TMFs), and Clinical Data Management Systems (CDMS).
Responsibilities
- Principal Investigator (PI): Responsible for reviewing and approving document corrections and version updates.
- Study Coordinator: Records corrections, maintains document version logs, and ensures timely filing.
- CRA/Monitor: Verifies corrections and version control during monitoring visits.
- Data Manager: Ensures electronic audit trails are maintained in CDMS/eCRFs.
- Sponsor/CRO: Provides oversight and ensures compliance with regulatory expectations.
- QA Officer: Audits document corrections, versioning, and audit trails during inspections.
Accountability
The PI is accountable for ensuring corrections are made transparently, with proper documentation and approval. Sponsors are accountable for audit trail maintenance and inspection readiness.
Procedure
1. Document Corrections (Paper)
Corrections must be made with a single line strike-through, with initials, date, and reason for correction.
No erasures, white-out, or overwriting allowed.
Late entries must be clearly marked with date and reason for delay.
2. Document Corrections (Electronic)
Electronic systems must maintain audit trails recording user ID, date, time, and reason for changes.
All changes must be traceable and not overwrite original entries.
3. Version Control
Maintain a version control system for SOPs, protocols, CRFs, and other essential documents.
Update the version number each time a change is made.
Retain superseded versions in archive with documentation of reason for revision.
Maintain Document Version Log (Annexure-1).
4. Audit Trails
Paper corrections must follow ALCOA+ principles.
Electronic systems must generate audit trail reports available for review during audits.
Audit trails must capture who, what, when, and why changes were made.
5. Review and Filing
PI reviews corrections and approves major version changes.
File all corrected and updated documents in ISF/TMF.
6. Archiving
Archive all corrected documents, superseded versions, and audit trail reports for a minimum of 15 years or per local regulations.
