What this study is about

Researchers are testing a new treatment, SC-CAR.GPC3xIL15.21 CAR T cells, to see if it's safe and effective for children with certain types of solid tumors that don't have cancer in the brain or spinal cord. The trial will involve collecting blood samples from eligible participants to create personalized CAR T cells targeting their specific tumor.
