1.2 Core Data Integrity Principles: ALCOA+

Vendor-hosted systems must support the principles of ALCOA+ to guarantee the integrity of GxP records. The acronym represents:

• Attributable: Every data entry or modification must be linked to the responsible individual.
• Legible: Data must be recorded in a permanent, clear, and readable manner.
• Contemporaneous: Data must be recorded at the time the activity occurs.
• Original: Data must be captured at the source or maintained as true copies.
• Accurate: Data must be correct, truthful, and reflective of the actual observations or activities.
• Complete: Records must include all required data, including metadata and audit trails.
• Consistent: Data changes and sequences should be logical and coherent.
• Enduring: Data must be durable and maintained for the required retention period.
• Available: Data must be accessible and retrievable throughout its lifecycle.

Compliance with these principles is fundamental to regulatory inspections and pharmaceutical quality oversight. Vendor-hosted platforms must demonstrably support controls enabling ALCOA+ compliance.

• Assess mechanisms for user account provisioning, deactivation, and periodic review.

2.4 Audit Trails and Electronic Signatures

Audit trails must be complete, time-stamped, and protected from tampering:

• Evaluate audit trail coverage for all critical data and system events.
• Confirm that electronic signatures meet regulatory criteria equivalent to handwritten signatures.
• Assess procedures for routine audit trail review and documentation.

2.5 Data Backup and Archiving

Critical GxP records hosted by the vendor must be regularly backed up and retained in compliance with regulatory retention policies:

• Review backup frequency, integrity verification, and restore testing.
• Confirm archival solutions support enduring legibility and retrievability.
• Ensure systems support data versioning preventing overwriting or loss.

At this stage, it is imperative to collaborate closely with IT, validation, and QA teams to obtain full visibility into the vendor-hosted system controls, ensuring an evidence-based assessment aligned with regulatory standards such as [EMA’s EU GMP Annex 11](https://ec.europa.eu/health/sites/default/files/files/eudralex/vol-4/2022-10_annex11.pdf).

Step 3: Evaluating Vendor Documentation and Compliance Programs

Effective review of vendor-hosted solutions requires structured evaluation of vendor-provided documentation paired with their compliance programs. This ensures the vendor is committed to maintaining GxP compliance in practice.

3.1 Quality Agreements and Service Level Agreements (SLAs)

• Review and approve quality agreements detailing responsibilities for data integrity, validation, and compliance oversight.
• Ensure explicit clauses addressing data ownership, confidentiality, and regulatory audit rights.
• Examine SLAs for defined uptime, system accessibility, and incident response timelines.

3.2 Vendor Data Integrity Policies and Procedures

Request documentation illustrating the vendor’s governance of data integrity, including:

• Policies mapping to ALCOA+ principles and clarifying electronic records management.
• Procedures for Dl remediation in response to data quality issues or anomalies.
• Description of regular self-inspections, internal audits, and corrective actions.

3.3 Data Integrity Training and Personnel Qualification

Personnel operating and maintaining vendor-hosted systems must be trained on GxP and data integrity concepts. Review:

• Proof of vendor staff training programs focused on data integrity training and Part 11/Annex 11 compliance.
