Adoptive cell therapy using chimeric antigen receptor (CAR) T cells have shown
|
|
promise in treating cancer, but manufacturing large numbers of high quality
|
|
cells remains challenging. Currently approved T cell expansion technologies
|
|
involve anti-CD3 and anti-CD28 antibodies, usually mounted on magnetic beads.
|
|
This method fails to recapitulate many key signals found \textit{in vivo} and is
|
|
also heavily licensed by a few companies, limiting its long-term usefulness to
|
|
manufactures and clinicians. Furthermore, highly potent, anti-tumor T cells are
|
|
generally less-differentiated subtypes such as central memory and stem memory T
|
|
cells. Despite this understanding, little has been done to optimize T cell
|
|
expansion for generating these subtypes, including measurement and feedback
|
|
control strategies that are necessary for any modern manufacturing process.
|
|
|
|
The goal of this dissertation was to develop a microcarrier-based degradable
|
|
microscaffold (DMS) T cell expansion system and determine
|
|
biologically-meaningful critical quality attitudes and critical process
|
|
parameters that could be used to optimize for highly-potent T cells. We
|
|
developed and characterized the DMS system, including quality control steps. We
|
|
also demonstrated the feasibility of expanding high-quality T cells. We used
|
|
Design of Experiments methodology to optimize the DMS platform, and we developed
|
|
a computational pipeline to identify and model the effects of measurable
|
|
critical quality attributes and critical process parameters on the final
|
|
product. Finally, we demonstrated the effectiveness of the DMS platform
|
|
\textit{in vivo}. This thesis lays the groundwork for a novel T cell expansion
|
|
method which can be utilized at scale for clinical trials and beyond.
