Abstrakt: While CAR-T cell therapy represents a major advance in personalized immunotherapy, the autologous nature of commercially available CAR-T products have delayed its broad application beyond a subset of hematological malignancies. In particular, manufacturing autologous CAR-T therapies is costly and time-consuming, and success relies on the fitness of a patient's cells. An allogeneic off-the-shelf CAR-T product could overcome these cell quality and quantity issues and could be accessed on-demand. However, a successful allogeneic CAR-T product will require multiplex gene knockout in addition to stable CAR integration to prevent graft-versus-host disease (GvHD) and graft rejection by the patient's immune system.
