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.

PRIMARY OBJECTIVE:
I. Find the maximum tolerated dose (MTD) of allogeneic haploidentical natural killer (NK) cell infusions with hu3F8 in patients with high-risk neuroblastoma (NB).
SECONDARY OBJECTIVES:
I. Estimate the anti-NB effect of allogeneic NK infusions plus hu3F8.
II. Assess the impact of killer immunoglobulin (Ig)-like receptors (KIR)/human leukocyte antigen (HLA) immunogenetics on disease response to NK/hu3F8.
III. Assess the relationship between cluster of differentiation (CD)16 polymorphism and antibody-dependent cellular cytotoxicity (ADCC) in vitro.
IV. Estimate hu3F8 pharmacokinetics.
OUTLINE: This is a dose-escalation study of allogeneic NK cells.
CHEMOTHERAPY: Patients receive cyclophosphamide intravenously (IV) over 6 hours on days -6 and -5.
Hu3F8 INFUSION: Patients receive hu3F8 IV over 30-90 minutes on days -1, 1, 5, 7, and 9.
NK INFUSION: Patients receive allogeneic NK cells IV on day 0.
ALDESLEUKIN: Patients receive aldesleukin subcutaneously (SC) on days 0, 2-4, 6, and 8.
Treatment may repeat for up to 2 additional cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 2, 3, 6, and 12 months.
