Objective
The objective of this Design Qualification (DQ) protocol is to establish that the Microfluidic Mixer is suitable for its intended use in the controlled formation of Liposomes and Lipid Nanoparticles (LNPs) in accordance with regulatory requirements.
Scope
This protocol applies to the Microfluidic Mixer used in the R&D and Production areas for the development and manufacture of Liposomes and LNPs.
Responsibilities
The Validation Team is responsible for executing the DQ protocol, documenting results, and ensuring compliance with acceptance criteria.
The Quality Assurance (QA) Team is responsible for the review and approval of the DQ protocol and results.
Prerequisites
All personnel involved must be trained in Good Manufacturing Practices (GMP) and have knowledge of the equipment operation and validation processes.
Equipment Description
The Microfluidic Mixer is designed for controlled nanoparticle formation, specifically for Liposomes and LNPs. It operates under specified critical parameters including flow ratio, total flow rate, temperature, mixing time, backpressure, and audit trail.
