e., histopathology (confirmed by the MSKCC Department of Pathology) or bone marrow metastases plus high urine catecholamine levels.

• - High-risk NB as defined by risk-related treatment guidelines1 and the International NB Staging System, i.e., stage 4 with (any age) or without (>365 days of age) MYCN amplification, MYCN-amplified stage 3 (unresectable; any age), or MYCN-amplified stage 4S.

• - Patients must have a history of tumor progression or persistent disease or failure to achieve complete response following standard therapy.

• - Patients must have evaluable (microscopic marrow metastasis, elevated tumor markers, positive MIBG or PET scans) or measurable (CT, MRI) disease documented after completion of prior systemic therapy.

• - Disease staging approximately within one month of treatment.

• - Prior treatment with murine and hu3F8 is allowed.

Patients with prior m3F8, hu3F8, ch14.18 or hu14.18 treatment must have a negative HAHA antibody titer. Human anti-mouse antibody (HAMA) positivity is allowed.

• - Concurrent malignancy or autoimmune disease.

- Donor is pregnant

Arms

Experimental: Humanized Anti-GD2 Antibody Hu3F8

This is a phase I study to assess the safety and feasibility of combining HLA-mismatched (KIR ligand incompatible) NK cells with hu3F8 in high-risk NB patients. Following chemotherapy, patients will be treated in sequential groups with a minimum of 3 patients/ dose of NK cells. Three dose levels of NK cells, starting at dose level 1, will be evaluated in this treatment protocol. The goal dose for each dose level is the high boundary (e.g. 9.9x10^6/kg in level 1; 14.9x10^6/kg in level 2, etc), but a range is provided to allow for cases where the goal dose cannot be achieved.

Interventions

Drug: - cyclophosphamide

chemotherapy with intravenous (IV) cyclophosphamide 50mg/kg/day (for patients with body weight<70kg) or 1500mg/m^2/day (for patients with body weight ≥70kg) for two days (days -6 and -5).

Biological: - NK cells

Day 0: NK cell infusion. NK cells are resuspended in Normasol at a concentration no less than 5 x 10^6cells/mL. The patient is pre-medicated as per standard cell product infusion. The cell product is infused through a central venous catheter. Patients will be evaluated clinically by vital signs pre- and approximately 30 minutes post infusion of NK cells and thereafter at approximately 1 hour intervals for 4 hours.

Biological: - hu3F8

On Days -1, +1, +5, +7 and +9 hu3F8 is administered at 1.68 mg/kg/day and infused over ~30-90 minutes

Drug: - rIL-2

On day 0, daily from +2 through +4, day +6, and day +8, rIL-2 is administered subcutaneously at 6 x 10^5 U/m^2/day.
