CAR-T cell manufacturing: Major process parameters and next-generation strategies

The success of CAR-T cell therapies is dependent on effective cell manufacturing that impacts product safety, efficacy, and patient accessibility. Here, we discuss major process parameters of autologous CAR-T cell manufacturing, regulatory considerations, and emerging technologies in therapeutic cell manufacturing. Chimeric antigen receptor (CAR)-T cell therapies have demonstrated strong curative potential and become a critical component in the array of B-cell malignancy treatments. Successful deployment of CAR-T cell therapies to treat hematologic and solid cancers, as well as other indications such as autoimmune diseases, is dependent on effective CAR-T cell manufacturing that impacts not only product safety and efficacy but also overall accessibility to patients in need. In this review, we discuss the major process parameters of autologous CAR-T cell manufacturing, as well as regulatory considerations and ongoing developments that will enable the next generation of CAR-T cell therapies.
