Real Time Online Chromatography Monitoring of Product Quality Attributes for Bio - ERP Spain.com - España y América Latina

REAL TIME ONLINE CHROMATOGRAPHY MONITORING OF PRODUCT QUALITY ATTRIBUTES FOR BIOLOGICS CONTINUOUS MANUFACTURING PROCESS The ever diversifying therapeutic modalities drive for modular and flexible bio-manufacturing, which transformed biologics process from traditional Fed-batch to Single Use BioReactor (SUB), then to Continuous Manufacturing (CM). Process Analytics evolve as critical enabling element of the CM process. It allows to move the release testing from the end of process to real time in the process, which not only eliminates weeks of material disposition delay, but also provides the process scientists product quality insight during the run to make process decisions. However, due to the structural complexity of the bio-molecules, spectroscopic sensors or probes nowadays lack the sensitivity and specificity to illustrate the product quality attributes (PQA) such as protein post translational modifications (PTM). We report here for the first time, we leverage a multi-functional automation system to directly take samples from the different stage of bio-process, purify, denature, derivatize and digest the samples before injecting onto the UHPLC and UHPLC/MS systems, one for online intact protein analysis, the other for Multiple Attribute Method (MAM) analysis for critical PTM PQAs. Benefiting from the high resolution chromatography and mass spectrometry, automated real time bio-molecule product quality monitoring is achieved for both SUB and CM process.
