  5. Slide 5: Mechanism of Action of MAR-T Cells

    5 • MAR - T cells target up to 6 antigens 1, 2 for a more potent, durable anti - tumor response. • MAR - T cells lack genetic modification; Natural T cells expanded ex vivo pose no mutagenesis risk. • MAR - Ts intend to address challenges faced by Bispecific Antibodies, CAR - T and TCR approaches. •

  6. Slide 6: MAR-T Cells are Generated in a Simple Manufacturing Process

    • No genetic engineering • Natural T cell expansion • Uninterrupted cell expansion • Reproducible process • Cost - effective process PBMC, peripheral blood mononuclear cells. 6 MAR - T Cells are Generated in a Simple Manufacturing Process
