About

This is an open single-arm clinical study aimed at evaluating the safety and tolerance of allogeneic γ9δ2 T cell injection in the treatment of patients with recurrent hematologic tumors after allogeneic hematopoietic stem cell transplantation.

Full description

To evaluate the safety and in vivo dynamics of allogeneic γ9δ2 T cell in the treatment of recurrent hematologic tumors after allogeneic hematopoietic stem cell transplantation patients, and to explore the appropriate therapeutic dose.
