The bone cancers Ewing sarcoma and osteosarcoma are some of the most common solid tumors occurring in children and young adults. When these tumors spread outside the bone where they start (metastatic disease) or they come back after initially going away (relapse), they are very aggressive and nearly impossible to cure. New treatments are urgently needed. CAR T cells are a type of therapy that uses a patient’s immune system to attack their cancer by recognizing a target on its surface. This target must be minimally expressed on normal cells to prevent toxicity. We have identified a target B7-H3 as being highly expressed on Ewing sarcoma and osteosarcoma and will now run a clinical trial testing antiB7-H3 CAR T cells in those diseases. We will also re-engineer these CAR T cells to be more effective in potential future trials.
