Accelerating CAR T cell manufacturing with an automated next-day process

The traditional method of CAR T cell production involves lengthy ex-vivo culture times which can result in the reduction of crucial naïve T cell subsets. Moreover, traditional CAR T cell therapy manufacturing processes can prolong time-to-patient, potentially delaying patient treatment, and contribute to disease progression. In this study, we describe an innovative and semi-automated 24-hour CAR T manufacturing process that yields a higher percentage of naïve/stem-cell like T cells which showed high cytotoxic activity and cytokine release in vitro. The data supports the feasibility of implementing this streamlined manufacturing process in clinics. This approach also has the potential to enhance CAR T therapy efficacy and improve patient access to therapy.
