OBJECTIVES: * Determine the maximum tolerated dose of monoclonal antibody 3F8 when administered with sargramostim (GM-CSF) in young patients with high-risk, refractory or relapsed neuroblastoma. * Assess anti-neuroblastoma effects of this regimen in these patients. OUTLINE: This is an open-label, dose-escalation study of monoclonal antibody 3F8. Patients receive sargramostim (GM-CSF) subcutaneously once daily on days -5 to 11 and monoclonal antibody 3F8 IV over 30 minutes on days 0-4 and 7-11. Treatment repeats every 4-6 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of monoclonal antibody 3F8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. After completion of study treatment, patients are followed every 3 months for 2 years.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

32 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

5 inclusion criteria required to participate

Prior treatment with 3F8 is allowed.

Age <21 years.

Patients must have a diagnosis of NB as defined by international criteria,45 i.e., histopathology (confirmed by the MSKCC Department of Pathology) or BM metastases plus high urine catecholamine levels.

Patients must have refractory or relapsed high-risk NB (including MYCNamplified stage 3/4/4S and MYCN-nonamplified stage 4 >18 months old) resistant to standard therapy.

Study Objectives

One single intervention group is designated in this study

This study does not include a placebo group

Treatment Groups

Group I

Experimental

One cycle has 5 days of 3F8 treatment. Each day, patients receive GM-CSF subcutaneously \~1.5 hr before the start 3F8 infusion. To limit side-effects, patients receive analgesics, antihistamines, and a small dose (IV, over \~5 minutes) of heat-modified 3F8. Cycles can be repeated after a 2-4 week interval, up to a total of two cycles.
