associated with erroneous print registration and barcode scanning, evaluating the likelihood and impact of these risks, and implementing controls to mitigate them. A risk management file documenting this assessment helps to ensure that all identified risks are tracked and adequately controlled during validation activities.

Key elements to include in the URS include:

• System functionalities (e.g., type of barcodes, print speed, maintenance procedures).
• Performance specifications (accuracy levels, fault tolerance, maintenance requirements).
• Compliance expectations (GMP, regulatory guidelines).
• User roles and responsibilities for system operation and maintenance.

Failure to adequately define requirements and assess risks can lead to substantial compliance issues down the line. It is advisable to engage cross-functional teams including QA, IT, and end users to collaboratively develop and review these documents before moving to the next validation phase.

2. Design Qualification (DQ)

Once the URS is finalized, the next step is Design Qualification (DQ). The DQ process ensures that the proposed system design is capable of fulfilling the requirements established in the URS. This includes verification of designs by evaluating vendor documents, design specifications, and compliance certifications in context with FDA Process Validation Guidance.

The DQ report should encompass documentation of how the system design aligns with regulatory requirements including:

• Design specifications vs. URS requirements.
• Vendor assessments, including quality history and performance record.
• System architecture analysis, including hardware and software components.
• Standard Operating Procedures (SOPs) pertaining to system operation.

The completion of DQ serves as a cornerstone for subsequent stages in the validation lifecycle. It sets benchmarks that guide the Installation Qualification (IQ) phase, ensuring accurate installation aligned with design specifications.

3. Installation Qualification (IQ)

The Installation Qualification (IQ) stage is essential to confirm that the system has been installed according to the approved design specifications. This process is highly procedural and requires detailed documentation to verify installation aspects, including:

• Physical and environmental conditions of installation.
• Functional testing of all components (hardware and software).
• Verification that all critical connections and integrations with other systems or equipment are operational.
• Review of installation protocols against the DQ documentation.

During this phase, a dedicated installation protocol should be devised, outlining all steps and acceptance criteria. This includes documenting who performed the installation, any deviations from the expected installation processes, and how those deviations were resolved. This documentation is essential in providing a traceable record demonstrating compliance with established standards.

Once IQ is complete, the stage is set for Performance Qualification (PQ), which involves operational testing of the system.

4. Performance Qualification (PQ)

Performance Qualification (PQ) is crucial for ensuring that the print registration and barcode systems function reliably under actual operating conditions. PQ involves comprehensive testing of the system using representative products and conditions to demonstrate that it performs according to specifications defined in the URS and DQ.

The PQ protocol should specify:

• The types of products and configurations to be tested.
• Operational parameters such as ink types, environmental factors, and their potential impact on barcode readability.
• Acceptance criteria for barcode accuracy and print clarity.

During testing, actual strip packs should be produced, and both barcodes and registration characteristics should be monitored for compliance with pre-defined criteria. Data gathered during these tests must be meticulously recorded, as this documentation serves as evidence of the system’s capabilities to regulatory agencies. This validation step assures ongoing compliance and helps eliminate potential product quality failures, thereby reducing risk to patients and ensuring compliance.

5. Continued Process Verification (CPV)

After successful completion of PQ, Continued Process Verification (CPV) is initiated. CPV is a proactive approach that involves continuously monitoring the performance of the print registration and barcode systems throughout their operational life. This aligns with the principles of ICH Q10 concerning pharmaceutical quality systems.

The objective of CPV is to ensure that process variability and product quality remain within acceptable limits. Key elements of CPV include:

• Selection of Critical Process Parameters (CPP) linked to product quality.
• Regular documentation and review of output data related to print registration and barcodes.
• Implementation of Statistical Process Control (SPC) methodologies to monitor systems.
• Periodic analysis of performance data to determine trends that might require investigation.

Through CPV, organizations can make informed decisions on when to intervene, ensuring compliance and maintaining product integrity over time. As part of good manufacturing practices, consistent data monitoring and analysis also assists in identifying potential issues before they escalate, thus safeguarding regulatory adherence.

6. Revalidation and Change Control

Validation is not a one-time event but an ongoing effort. Changes to the validated system, whether due to upgrades, changes in materials, or the introduction of new equipment, require a thorough evaluation to determine whether revalidation is necessary. The change control process should integrate a risk-based approach as defined in ICH Q9.

During revalidation, the scope should be determined based on the nature of the changes made. Critical components requiring further validation might include:

• Modification of software updates impacting print registration accuracy.
• Changes in packaging materials affecting barcode scanning.
• Realignment of process parameters that could deviate from validated specifications.

Comprehensive documentation must be maintained to reflect all changes, associated impacts on product quality, and verification actions taken. Each change should undergo risk assessment and approval similar to the initial validation lifecycle to ensure that the system’s integrity is maintained continuous compliance with EMA guidelines.

In summary, effective management of the validation lifecycle for print registration and barcode systems in strip packs is foundational in meeting the regulatory demands while securing product quality. By adhering to these structured validation steps and maintaining thorough documentation, organizations will be better positioned to ensure compliance and optimize the performance of their packaging systems.
