Indutrialization of Stem Cell Processes – how to identify
Indutrialization of Stem Cell Processes – how to identify the right strategy ? ISCT, April 26, Paris Jose Castillo Cell Culture Technologies Director Pall Life Sciences Agenda Pall Life Sciences and the cell therapy industry Process industrialization challenges Integrating available technologies in process development and manufacturing Pall approach Pall Life Sciences Where we come from? PALL LIFE SCIENCES Pall supports leading companies in the field of vaccines, MAbs and protein production for 10 years Pall offers process intensification integrated technologies for cell culture based processes Pall leverages process development competencies to develop intensification innovative technologies and efficient processes Pall Life Sciences “Customer Problem Solving” approach Application & Development Centers Pall approach combines both Product development , Process development & optimization PALL/ATMI has two Applications & Development centers: Equipped cell culture clean rooms. 45 experienced team including Engineers & Bioengineers PD for New Bioreactor development PD Services / Support of our technologies Tech transfer to your facility or to your CMO Brussels Minneapolis 500m² 100m² Class 10,000 (ISO 7) Non-classified BSL-2 BSL-2 PALL Life Sciences The offer for the cell therapy industry Complete solutions for cell based product manufacturing Offer the complete solution for cell grow and harvest based on the best technologies available, Pall and others Leverage our expertize in stem cells process development to streamline industrialization of cell therapy products Optimize process and enable high volume manufacturing of cell based therapies Develop second generation solutions Process industrialization challenges The process is the product Manuf. Process QA system Validation Supply Capacity Availability Product CAPEX Facility Costs Costs of Goods Affordablity Upstream technologies Available & next generation systems Surface area cm²/unit > 1M 122,400 25,000 18,000 Hollow fiber Bioreactors Multilayer Stacks • Terumo • Biovest • Fibercell • Corning • Thermo Fisher Multilplate Bioreactors Microcarrier stirred tank • PALL • • • • • PALLSoloHill TFS Millipore Sartorius GEHC Others (Microfibers, hydrogel, ...) Scale-up in multilayer systems Technical and manufacturing considerations Multilayer Systems Limited process development needs Manufacturing strategy = Scaleout Large facility & labor intensive Automation has to be considered Scale-up in multilayer systems Technical and manufacturing considerations Multilayer Bioreactors Process development is required: Optimize process parameters Harvest protocol Keep same micro-environement as multilayer, so reduce process development time and regulatory risk Linear scalability from 10 to 200 plates (122,400 cm²) Enable scaling up while minimizing footprint and reducing manual operations Scale-up with microcarriers Technical and manufacturing considerations Microcarriers Process development challenges: time & expertise Microcarrier: Density, cm²/g, g/L achievable, surface coating Impacts on : mixing requirements, cells/ml and product quality Bioreactor: Seed train (bead to bead transfer) and scale up Low shear while maintaining mixing efficiency Scalable harvest protocol Product quality / similarity vs 2D layers Requires Process development: Clinical development timelines need to be considered May need clinical bridging data Very high volume manufacturing Downstream process scale-up Considerations Intermediate storage not allowed Streamline the unit operations of the complete manufacturing process Main challenges for downstream at large scale : Cells detachment from 2D multilayers / multilayer bioreactors / microcarriers Microcarrier / cells separation Cells concentration & washing Formulation In-line filling Downstream process scale-up Available technologies Criteria for technology selection: Harvest volumes to process Cells integrity / resistance to mechanical constrains Time constraints Concentration factor and final targeted volume Technology scale and associated R&D efforts Ana S.
