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.\n\nB7H3 (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.\n\nBy 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",[83,84,85],"Advanced Solid Tumors","Ovarian Cancers","Peritoneal (metastatic) Cancer",[87,88,89],"cell therapy","γδT","CAR-T","NOT_YET_RECRUITING","2025-02-09",{"date":93,"type":94},"2025-02-13","ACTUAL",{"date":96,"type":77},"2025-03-01",{"date":98,"type":77},"2027-12-31",{"name":5,"class":6},1]
