Donor Natural Killer Cells and Hu3F8 in Treating Patients with High-Risk Neuroblastoma

Trial Status: complete

This phase I trial studies the side effects and best dose of donor natural killer cells when given together with naxitamab (hu3F8) in treating patients with neuroblastoma that has not responded to standard treatment or has returned after treatment. Natural killer cells are a type of white blood cell that can recognize and kill abnormal cells in the body, and can work together with antibodies to kill target cells. Immunotherapy with monoclonal antibodies, such as hu3F8, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving donor natural killer cells together with humanized monoclonal antibody 3F8 may kill more cancer cells.
