Purpose

The purpose of this SOP is to establish a standardized approach for the validation of the Inline Particle Size Analyzer used in the production of long-acting injectables, ensuring compliance with regulatory requirements and product quality standards.

Scope

This SOP applies to the Inline Particle Size Analyzer utilized in the production area for monitoring particle size in depot suspensions, including all validation phases: DQ, IQ, OQ, and PQ.

Definitions

• DQ: Design Qualification
• IQ: Installation Qualification
• OQ: Operational Qualification
• PQ: Performance Qualification
• CSV: Computer System Validation

Roles

• Validation Team: Responsible for executing and documenting validation activities.
• Quality Assurance: Ensures compliance with regulatory standards and reviews validation documentation.
• Production Personnel: Operate the Inline Particle Size Analyzer during production.

Lifecycle Procedure

1. Design Qualification (DQ): Assess the design specifications and intended use of the Inline Particle Size Analyzer.
2. Installation Qualification (IQ): Verify that the equipment is installed according to manufacturer specifications and is operational.
3. Operational Qualification (OQ): Confirm that the equipment operates within specified limits under controlled conditions.
4. Performance Qualification (PQ): Validate that the equipment performs as intended in the production environment.

GDP Controls

Good Documentation Practices (GDP) must be followed throughout the validation process. All records should be clear, accurate, and complete, ensuring traceability and accountability.

Acceptance Criteria Governance

Acceptance criteria for the Inline Particle Size Analyzer include:

• Accuracy: The equipment must provide measurements within specified tolerance limits.
• Precision: Repeated measurements should yield consistent results.
• Data Integrity: All data must be recorded accurately and securely.
• Audit Trail: A complete audit trail must be maintained for all data generated by the analyzer.

Calibration/PM Governance

The Inline Particle Size Analyzer must undergo regular calibration and preventive maintenance (PM) as per the manufacturer’s recommendations to ensure accurate performance.

Change Control Triggers

Any changes to the Inline Particle Size Analyzer or its operating procedures must be assessed for impact on validation status and documented through the change control process.

Revalidation Triggers and Periodic Review

Revalidation of the Inline Particle Size Analyzer is required under the following conditions:

• Significant changes in equipment or procedures.
• Failure to meet acceptance criteria during routine monitoring.

A periodic review of the validation status should be conducted annually or as required by regulatory guidelines.
