Allogeneic stem cell transplantation is a treatment option for patients with advanced Ewing sarcoma (ES). Donor T cells can mediate a graft versus tumor effect to eradicate cancer. However, this treatment can also result in life threatening graft vs. host disease. We isolated tumor specific T cells from healthy donors directed against ES associated target antigens. The sequences of ES specific T cell receptors were retrovirally introduced into donor T cells and tested for in vitro specificity and in vivo efficacy.
