Experimental: humanized anti-GD2 antibody, hu3F8, when combined with GM-CSF
One cycle consists of treatment with hu3F8 at a dose of 2.4mg/kg/dose for 3 days (day 1, 3, and 5) in the presence of subcutaneous (sc) GM-CSF (day -4 through 5). These 3 doses of hu3F8 and 10 days of GM-CSF constitute a treatment cycle. Cycles are repeated at ~2-4 week intervals between first days of hu3F8, through 5 cycles. A maximum of 5 cycles will be administered on protocol. If elevations of amylase and/or lipase (>Grade 1) or clinical signs suggestive of pancreatitis (e.g. upper abdominal pain) occurs, naxitamab and GM-CSF doses should be held until improvement of toxicity to ≤Grade 1 if laboratory elevations and/or pancreatitis is possibly related to either naxitamab or GM-CSF.

- event free survival (EFS) [ Time Frame: 12 months ]EFS is defined as the time from surgery to relapse or death from any cause, recurrence of tumor or second malignancy.
- time to recurrence [ Time Frame: 12 months ]Time to recurrence will be estimated using Kaplan-Meier methods. Very few patients are expected to die without relapse (<5%). Recurrence is defined as the radiographic presence of any new lesion that is not attributable to differences in scanning techniques, change in imaging modality or findings thought to represent something other than osteosarcoma, or if a biopsy is performed which shows osteosarcoma.

Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients must have recurrent OS. OS must be verified by histopathology review by the site's Department of Pathology. (Patients registered at MSK must have pathology confirmed by MSK Department of Pathology.)
- Patients must be in a ≥2nd complete remission as indicated by appropriate radiologic evaluations at the time of study entry.
- Patients must be ≥ 1 year of age and ≤ to 40 years of age at the time of enrollment.
- Prior therapy: ≥3 weeks should have elapsed since last cytotoxic therapy, immunotherapy or radiation therapy. More than one week should have elapsed since major surgery.
NOTE: Minor surgery (e.g. minor biopsy, central venous catheter placement, shunt revision) is permitted within 1 week prior to enrollment)
