TCR-based therapeutics demonstrate significant advantages and promising prospects. Compared to CAR-T, TCR-T cells can recognize intracellular antigens, exhibit superior infiltration into solid tumors, and show a lower incidence of cytokine release syndrome (CRS). TCR protein drugs further overcome the limitations of cell-based therapies, offering advantages such as lower costs, simpler production processes, and enhanced safety profiles, enabling the extension of TCR therapies to a wider range of therapeutic areas. In addition, soluble TCR can also be used in TCE therapies.
