What this study is about

Researchers are testing a new treatment called B7-H3 CAR T cells to see if it can help children with certain types of solid tumors. The trial will evaluate the safety and how well this treatment works in kids aged 18 or younger who have relapsed or refractory B7-H3+ solid tumors. It aims to determine the maximum safe dose of these CAR T cells.
