Developing Scalable Upstream Workflows For Recombinant And Viral Vaccine Processes


There is huge pressure on biomanufacturing facilities due to high demand for gene therapy products such as recombinant adeno-associated viral (AAV) vectors made under current good manufacturing practice (GMP) conditions. The constraints of the scale-up process are rarely taken into consideration during clinical process development, with many facilities simply scaling-out adherent cell stack protocols, procedures, and test methods. In order to demonstrate the importance of cost economics linked to the choice of scale-up processes, this study provides a detailed cost modeling analysis comparing viral vector production in adherent cells in cell stacks to viral vectors produced in bioreactors, either in suspension using a stirred bioreactor or adherently in iCELLis® fixed-bed bioreactor.
