Anti-GD2 3F8 Antibody and Allogeneic Natural Killer Cells for High-Risk Neuroblastoma
Funding Source - FDA OOPD FDR004128
The goal of this study is to see if it is safe and feasible to give chemotherapy, natural killer (NK) cells, and an antibody called 3F8. The NK cells must come from a family member who shares half of the HLA proteins which are immune proteins important in transplant. NK cells are a type of white blood cell. They can recognize and kill abnormal cells in the body and can work together with antibodies to kill target cells. The antibody 3F8 specifically recognizes a protein present on the target cancer cell.

Experimental: chemotherapy, allogeneic NK cells, 3F8
This is a phase I study to assess the safety and feasibility of combining HLA-mismatched (KIR ligand incompatible) NK cells with 3F8 in high-risk NB patients. Following chemotherapy, patients will be treated in sequential groups of 3 patients/dose of NK cells. Four dose levels of NK cells, starting at dose level I, will be evaluated in this treatment protocol. In the unlikely case toxicity is encountered at dose level I, patients will then be treated at the lower dose level 0. Patients can receive up to 3 cycles of treatment on protocol. For subsequent cycles, patients will be treated at either less than or at the same dose level of NK cells as their first cycle.
Drug: cyclophosphamide, vincristine, topotecan ,allogeneic NK cells & 3F8
Patients will receive combination chemotherapy with intravenous (IV) cyclophosphamide 70mg/kg/day (for patients with body weight<70kg) or 2100mg/m2/day (for patients with body weight ≥70kg) for two days, IV vincristine 0.067mg/kg or 2mg/m2/day (lower of the two doses to be chosen; maximum 2mg) for one day, and IV topotecan 2.4 mg/m2/day for 3 days during their first cycle. If receiving a second and/or third cycle, the only chemotherapy patients will receive is cyclophosphamide at 50 mg/kg/day for 2 days. On Day 0, patients will receive a single dose of allogeneic NK cells isolated from a HLA-haploidentical related donor. On day +3, the patient will start daily infusion of 3F8 for 5 days. The treatment schedule may require minor adjustment by ±1 day as clinically indicated (e.g. due to PDH closure for holidays or due to inclement weather).
