Standard Operating Procedure for Equipment Validation of Liposome Extruders

Purpose: This SOP outlines the validation process for the Extrusion System (Liposome Extruder) used in the production of liposomes and lipid nanoparticles, ensuring compliance with regulatory requirements and product quality standards.

Scope: This procedure applies to the validation of the Liposome Extruder within the R&D and Production areas, focusing on size control via membrane extrusion.

Definitions:

• Equipment Validation: A documented process that demonstrates that a specific piece of equipment operates consistently and produces results that meet predetermined specifications.
• Extrusion System: Equipment used for size control of liposomes and lipid nanoparticles through membrane extrusion.
• Criticality: The importance of the equipment in affecting product quality and consistency.

Roles:

• Validation Team: Responsible for executing the validation protocol and ensuring compliance with this SOP.
• Quality Assurance: Oversees the validation process, ensuring adherence to regulatory standards.
• Maintenance Personnel: Conducts calibration and preventive maintenance as per schedule.

Lifecycle Procedure:

1. Design Qualification (DQ): Assess the design specifications against user requirements.
2. Installation Qualification (IQ): Verify that the equipment is installed correctly and meets operational specifications.
3. Operational Qualification (OQ): Test the equipment under normal operating conditions to ensure it performs as intended.
4. Performance Qualification (PQ): Confirm the equipment consistently produces results that meet quality standards under actual production conditions.

Good Documentation Practices (GDP) Controls: All documentation related to the validation process must be completed accurately, reviewed, and approved by authorized personnel. Records must be maintained in a secure location.

Acceptance Criteria Governance: Acceptance criteria must align with the User Requirement Specifications (URS) and Annex 11 regulatory guidelines. All results must be documented and deviations addressed.

Calibration and Preventive Maintenance Governance: The Extrusion System must undergo calibration and preventive maintenance as per the established schedule. Records of calibration and maintenance activities must be retained for audit purposes.

Change Control Triggers: Any modifications to the equipment, process, or operating procedures require a change control assessment to determine the impact on validation status.

Revalidation Triggers and Periodic Review: The equipment must be revalidated every 12 months. Additionally, any significant changes in process or product specifications may trigger an immediate revalidation.
