Operational Qualification Protocol for Liposome Extruder

Objective

The objective of this protocol is to establish and document the operational qualification of the Liposome Extruder used for size control via membrane extrusion in the R&D/Production area.

Scope

This protocol applies to the Liposome Extruder utilized in the development and production of liposomes and lipid nanoparticles, ensuring compliance with regulatory requirements and validation standards.

Responsibilities

• Validation Team: Responsible for executing the protocol and documenting results.
• Quality Assurance: Responsible for reviewing and approving the protocol and results.
• R&D/Production Staff: Responsible for operating the equipment as per the validated procedures.

Prerequisites

• Completion of Installation Qualification (IQ).
• Training of personnel on the operation of the Liposome Extruder.
• Availability of necessary materials and equipment for testing.

Equipment Description

The Liposome Extruder is an extrusion system designed for the size control of liposomes and lipid nanoparticles through membrane extrusion. It operates under controlled pressure and temperature conditions to ensure consistent product quality.

Test Plan

Detailed Test Cases

Test Case OQ-01: Pressure Verification

Procedure: Set the equipment to operational mode and verify that the pressure gauge reads within the defined range.

Acceptance Criteria: Pressure must be within specified range (100-300 psi).

Evidence: Documented pressure log.

Test Case OQ-02: Membrane Pore Size Check

Procedure: Inspect the membrane used in the extruder to confirm it meets the specified pore size.

Acceptance Criteria: Pore size must match specifications.

Evidence: Membrane specifications document.

Test Case OQ-03: Temperature Monitoring

Procedure: Monitor the temperature during operation and ensure it remains stable.

Acceptance Criteria: Temperature must be maintained between 25-30°C.

Evidence: Temperature log records.

Test Case OQ-04: Flow Rate Measurement

Procedure: Measure and record the flow rates during the extrusion process.

Acceptance Criteria: Flow rates must be consistent with operational parameters.

Evidence: Documented flow rate records.

Deviations

Any deviations from the acceptance criteria must be documented and investigated. A corrective action plan should be developed and implemented as necessary.
