Patient case: 26-year-old male with Liposarcoma. Genetic variant: MDM2 Amplification. Other conditions: None.

Clinical trial: Humanized Anti-GD2 Antibody Hu3F8 and Allogeneic Natural Killer Cells for High-Risk Neuroblastoma

Summary: This is a phase I study. The purpose of this study is to see if it is safe and feasible to give the participant cyclophosphamide (a type of chemotherapy), natural killer (NK) cells, and an antibody called Hu3F8 as a treatment for neuroblastoma. NK cells are a type of white blood cell.
