Standard Operating Procedure for Equipment Validation of High Pressure Homogenizer and Microfluidizer

Purpose: This SOP outlines the validation process for the High Pressure Homogenizer and Microfluidizer used in the development and production of liposomes and lipid nanoparticles (LNP).

Scope: This procedure applies to all personnel involved in the validation of the High Pressure Homogenizer and Microfluidizer within R&D and production environments.

Definitions:

• High Pressure Homogenizer: A device used for size reduction and uniformity of lipid formulations.
• Microfluidizer: A high shear device that enhances the uniformity and size distribution of nanoparticles.
• Validation: The process of establishing documented evidence that a system consistently produces a result meeting predetermined specifications.

Roles:

• Validation Team: Responsible for executing validation protocols and ensuring compliance with regulatory standards.
• Quality Assurance: Ensures that all validation activities comply with relevant guidelines and regulations.
• Equipment Operators: Responsible for operating the equipment in accordance with validated procedures.

Lifecycle Procedure:

1. Design Qualification (DQ): Verify that the equipment design meets user requirements.
2. Installation Qualification (IQ): Confirm that the equipment is installed correctly and according to specifications.
3. Operational Qualification (OQ): Demonstrate that the equipment operates within specified limits.
4. Performance Qualification (PQ): Validate the equipment’s performance with actual product under real conditions.

GDP Controls: Good Documentation Practices must be followed throughout the validation process to ensure traceability and compliance.

Acceptance Criteria Governance: Acceptance criteria shall be established in accordance with User Requirement Specifications (URS), Annex 11, and Annex 15 of the relevant regulatory guidelines.

Calibration/PM Governance: The equipment must undergo regular calibration and preventive maintenance as per the manufacturer’s recommendations and internal policies.

Change Control Triggers: Any modifications to the equipment or its operating procedures must be documented and assessed for impact on validation status.

Revalidation Triggers and Periodic Review: Revalidation is required annually or whenever there is a significant change in equipment, process, or product.
