SIPAT core business PAT Data management
“In God we trust. All others must bring data” (W. Edwards Deming)
Principle of PAT & QbD Real-timerelease Advanced Control Quality buillt in by design Right first time PAT monitoring product quality mathematical translation Classic control Lab Process data (Temp, Pressure, Oxygen, …) monitoring analyzer data LIMS Closed loop control Hold / release Process feed Process Analyzer Sample Process output
PAT data management Analyzer data Context & Info Data Raw material data SIPAT Runtime Data Off line results Real Time Calculations LIMS data Process data
PAT data management Quantitative result Analyzer data Context & Info data Raw material data SIPAT Runtime data Off line results Real time calculations LIMS data Process data Qualitative result
PAT data management SIPAT External application Meta & Context Data Analyzer Data (NIR, Raman, PSD, …) Process Data Predicted Data Off- line lab Data (RM, process samples,…) Other data • Batch number • Trial number • Process step • Product • Campaign • …. Create Model
PAT Toolbox Product & process design PAT (Advanced) ProcessControls Information managementtools Data Collection storage & retrieval DoE Data Analysis & mining ProcessAnalytics PAT requires multidisciplinary skills & Tools Complex data management
Going continous – the consequences Continuous manufacturing needs a mindshift on different levels: • Need for a tight integration between process, PAT analyzers and control mechanisms • Continuous quality verification must be established • Translation of Batch oriented release guidelines to a continuous production • How to define a batch? • Ensure the traceability of products trough the line • product genealogy • Alignment of information • Completely different production equipments are needed
Why moving to continuous manufacturing? Why move towards CM operation? • Many advantages perceived in CM • Smaller equipment • Smaller facility • Easier scale-up • Better control • Improved yield • Reduced waste • Improved Safety • Flexible Manufacturing (For personalized medicine/Targeted therapies) • Reduced cost • Improved quality

Bring this is in a continuous production train Solutions Changes upstream Changes downstream • Smaller reactor sizes vs “Stainless Steel Cathedrals” • Perfusion reactors • Focus more on disposables • Smaller chromatography Columns • Integrated operations • (adjusted flow rates, pH, osmolality etc) The challenges on data mgt & control • Batch definition • Traceability & genealogy • Need for online monitoring PAT! • Need for integrated data management • Alignement of data & information
Bring this is in a continuous production train Solutions Solutions PAT technology • Integrated PAT data management • Harvest Point - optimums • Golden batch comparison • Real Time Release • Advanced Process Control • Spectroscopy (NIR, MIR, UV, Raman, LIF) • Off-Gas analysis • Online GC/HPLC • Online rapid analysis equipment + MVDA
Data flows… Upstream Control & Information flows Downstream Control & Information flows • Read data from chromatography or other purification steps • Integrate data from fermentation step to predict impurities etc. in purification steps • Closed loop control inside reactor (Feedback control) • Feeding control in reactor (Feedback control) • FeedForward control from precultures to next steps (Precultural conditions!)
Where are the challenges? Batch definition Traceability & genealogy Flexible & Modulardynamicproduction environments required • Must bereflected in data management landscape! • Flexibleproductionskids • Disposablesystems • Flexibleanalysers • Robust models • Dynamiclogics & control models • Must bebasedonstandardisation (OPC DA & UA) • Requires high flexibility and interactionbetween different componentslike • SCADA • DCS • PAT analysers • Controlstrategies
