Outlook: ACTallo ® IMA301 – Immatics’ Allogeneic Cell Therapy Approach Effective Redirection of γδ T cells Using αβ TCR 28 • Proprietary manufacturing protocol delivering robust expansion of γδ T cells with the potential for hundreds of doses from one single donor leukapheresis • Off - the - shelf cell therapy , applicable without need for personalized manufacturing and not reliant on potentially encumbered immune system of patient • High potency: TCR transduced γδ T cells show similar anti - tumor activity to αβ T cells • Proprietary single lentiviral vector system (4 - in - 1 construct) including TCR and CD8 alpha & beta chains • γδ T cells are abundant, show intrinsic anti - tumor activity, naturally infiltrate solid tumors and do not cause graft - vs - host disease γδ T cell collection from healthy donor Off - the - shelf product Transduction Expansion ACTallo® Immatics’ Allogeneic ACT Approach ACT
