Transition from manual to automated processes for autologous T cell therapy manufacturing using bioreactor with...

Transition from the manual processes that are performed during the initial research and development (R&D) stage to automated processes for later and commercial stage cell therapy manufacturing can be challenging. It often requires significant effort, time, and costs - which hinders the therapy's access to the clinic. To ease this transition, we have developed a novel and flexible manufacturing platform, Bioreactor with Expandable Culture Area (BECA), that aims to support both R&D and manufacturing to accelerate cell therapies from bench to bedside. This report introduces two models in this manufacturing platform: BECA-S for manual small-scale operation at R&D phase and BECA-Auto for functionally closed and automated scaled-out operation at manufacturing phase. We employed these two models to streamline transition of the T cell culture process from manual to automated and reported insignificant differences in the culture outcome between the two. Our work represents the first detailed development and demonstration of a standalone cell manufacturing platform that facilitates a seamless transition between manual and automated processing for autologous T cell therapy manufacturing.
