T cell transduction (TCT) on the CliniMACS Prodigy

Chimeric antigen receptor (CAR) T cell therapy is undoubtedly leading a revolution in cancer therapy1,2. The recent successes of CAR T cell therapy in fighting hematologic malignancies have led to a tremendous increase in interest in the immunotherapeutic field³. The great potential of genetically modified T cells now even expands into the area of solid tumors and infectious diseases⁴. Currently, the manufacturing process of engineered T cells consists of various complex procedures, is labor intensive, and represents one of the biggest challenges in this area. The CliniMACS Prodigy T cell transduction (TCT) process provides a unique all-in-one solution to these challenges. With the CliniMACS Prodigy Platform it is possible to generate gene-modified T cells in a standardized and fully automated process. It is a  breakthrough in cell manufacturing, a leap to the next generation.

CliniMACS Prodigy T Cell Transduction Process

With the CliniMACS Prodigy T Cell Transduction Process you can now generate gene-modified T cells in a simple and fully automated way. Easy to use, this unique process will surely change the way you work. 

The CliniMACS Prodigy Platform enables the entire workflow for the manufacture of CAR T cells, from T cell selection through to cell formulation. Importantly, all cell processing steps are completely automated, ensuring a highly reproducible and standardized manufacturing process. During the TCT process, T cells are enriched by specific selection on day 0 (D0) and then activated overnight. On D1 T cells are transduced with a (lentiviral) vector. Subsequently, transduced T cells are expanded to the desired cell number for final cell formulation (D10–14).

For the manufacture and use of gene-engineered T cells, national and international legislation and regulations must be followed. Miltenyi Biotec as the provider of products for the TCT process does not give any recommendation regarding the use of the manufactured cells for therapeutic purposes and does not make any claim regarding a clinical benefit.

Clinical-scale isolation of T cells

Cell separation on the CliniMACS Prodigy is a simple and easy method to magnetically isolate T cells with high purity. Advantages of this completely automated method include:

  • Efficient isolation of CD4+ and CD8+ cells without inducing activation
  • Removal of contaminating immune cells to enhance T cell transduction efficiency
  • No magnetic bead removal necessary

GMP-compliant activation and expansion of T cells

T cells activated with MACS GMP T Cell TransAct
View details

MACS GMP T Cell TransAct™ has been designed to activate and expand enriched T cell populations or human resting T cells from peripheral blood mononuclear cells (PBMCs). The reagent can be sterile filtered, and excess reagent can conveniently be removed by washing.

MACS GMP T Cell TransAct is directly applicable for the use in automated culture systems, such as the CliniMACS Prodigy Instrument.

Lentiviral vectors for T cell transduction

Lentigen Technology Inc., a Miltenyi Biotec company, integrates LV manufacturing competency into the CliniMACS Prodigy workflow solutions for the production of gene-modified cell therapy products. Located right outside of Washington DC, the 34,000 ft2 facility has two cGMP ISO7 lentiviral vector production suites and offers a serum-free manufacturing process on 50 L to 400 L scale.
