Tumor-infiltrating lymphocytes: Streamlining a complex manufacturing process

Published:November 30, 2018DOI:https://doi.org/10.1016/j.jcyt.2018.11.004

      Abstract

      Adoptive cell therapy of tumor-infiltrating lymphocytes has shown promise for treatment of refractory melanoma and other solid malignancies; however, challenges to manufacturing have limited its widespread use. Traditional manufacturing efforts were lengthy, cumbersome and used open culture systems. We describe changes in testing and manufacturing that decreased the process cycle time, enhanced the robustness of critical quality attribute testing and facilitated a functionally closed system. These changes have enabled export of the manufacturing process to support multi-center clinical trials.
