Introduction of PAT to improve the Efficiency and Robustness of Vaccine Development and Manufacturing

Challenges in monitoring the quality of vaccine production
• Process Analytical Technology (PAT) ensures process reproducibility in bioprocessing
• A mechanism to design, analyze and control pharmaceutical manufacturing processes through the measurement of critical process parameters (CPP) which affect product quality attributes (CQA)
• Initiated by the FDA as part of the 21st Century GMP initiative in 2001 with the goal of increasing productivity
• Application of PAT in vaccine development and manufacturing is challenging due to the sample complexity and batch-to-batch variability.
• During the development of an up- and/or down-stream process of the target biomolecule, a fast, accurate and reliable analytical method is requried for determining the quantity and purity of the product intended for human use

Solution: Convective Interaction Media Monoliths
• Monoliths are chromatography media cast as a single block, inserted into a housing
• Highly inter-connected network of channels (1-2 μm) containing functionalised binding sites for large biomolecules (viruses, VLPs, pDNA, antibodies)
• Performance unaffected by increasing the flow rate or molecular size
