Objective
The objective of this Design Qualification (DQ) protocol is to ensure that the Inline Static Mixer used in the formation of Liposomes and Lipid Nanoparticles (LNP) meets specified requirements and operates effectively within defined parameters.
Scope
This protocol applies to the Inline Static Mixer utilized in the R&D and Production areas for mixing during the formation of NDDS, specifically Liposomes and LNPs.
Responsibilities
- Validation Team: Responsible for executing the DQ protocol and documenting results.
- Quality Assurance: Responsible for reviewing and approving the DQ protocol and results.
- Engineering: Responsible for providing technical support and ensuring equipment compliance.
Prerequisites
- Completion of User Requirements Specification (URS).
- Installation Qualification (IQ) of the Inline Static Mixer.
- Training of personnel on the operation of the Inline Static Mixer.
Equipment Description
The Inline Static Mixer is designed for mixing fluids in a continuous process. It utilizes a series of static mixing elements to achieve uniform mixing of components without the need for moving parts. The equipment is critical for ensuring the proper formation of Liposomes and LNPs.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| DQ-ISMLNP-001 | Measure mixing efficiency and pressure drop across the mixer. | Mixing efficiency meets URS requirements; pressure drop within acceptable limits. | Calibration records, test data logs. |
Detailed Test Cases
Test Case 1: Mixing Efficiency
Procedure: Conduct a series of mixing trials using predetermined formulations. Measure the concentration of the final product to determine mixing efficiency.
Acceptance Criteria: Mixing efficiency must meet the specifications outlined in the URS.
Evidence: Documented results from mixing trials, including concentration data.
Test Case 2: Pressure Drop Measurement
Procedure: Measure the pressure drop across the Inline Static Mixer during operation at various flow rates.
Acceptance Criteria: Pressure drop must remain within the limits defined in the URS.
Evidence: Recorded pressure drop measurements during testing.
Deviations
Any deviations from the acceptance criteria must be documented and investigated. A root cause analysis will be performed, and corrective actions will be implemented as necessary.
