About this trial

γδT cells can directly recognize non-peptide tumor antigens, such as IPP phosphorylated metabolites, without relying on specific major histocompatibility complexes (MHCs). This unique characteristic leads to a lower risk of graft-versus-host disease (GVHD). The clinical safety of γδT cells in allogeneic tumor therapies has been validated multiple times, highlighting their significant potential in developing universal CAR-T cell therapies.

B7H3 (CD276), a member of the B7 negative co-stimulatory molecule family, is minimally expressed or absent in normal tissues but highly expressed in various tumor tissues. As a result, B7H3 is regarded as a highly promising tumor-associated antigen and a universal drug target with substantial therapeutic potential.

By utilizing γδT cells as carrier cells, the development of universal B7H3 CAR-γδT cell injections for advanced solid tumors can effectively address risks such as autologous cell preparation failure and treatment delays. This innovative approach offers a highly efficient solution for solid tumor treatment and holds great promise for advancing immunotherapy in this field
