-
Diagnosis of NB as defined by a) histopathology (confirmed by the MSKCC Department of Pathology), or b) BM metastases or MIBG-avid lesion(s) plus high urine catecholamine levels.
-
Patients must have high-risk NB (including MYCNamplified stage 2/3/4/4S of any age and MYCN-nonamplified stage 4 in patients greater than 18 months of age) AND:
-
Phase I: Patients must have refractory or relapsed NB, resistant to standard therapy*.
*For NB, standard therapy includes intensive induction chemotherapy, followed by a variety of consolidation or salvage therapies, depending on response.
-
Phase II: Patients must have primary or secondary refractory disease in BM, defined as morphologic evidence of NB in BM and/or abnormal 123I-MIBG uptake in osteomedullary sites, OR patients patients in ≥ 2nd CR patients are in ≥2nd CR
-
Patients must be older than 1 year of age.
-
Prior treatment with murine and humanized 3F8 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.

- Arm && Interventions
Group Intervention Description Hu3F8 with GM-CSF Hu3F8 With GM-CSF The phase I single arm trial assesses escalating doses of iv hu3F8 (days 1, 3, 5) in the presence of sc GM-CSF (day -4 through 5). These 3 doses of hu3F8 and 10 days of GM-CSF constitute a treatment cycle. The expansion phase II single arm trial assesses the anti-NB activity of hu3F8+GM-CSF.in 3 groups of patients: Group 1 patients have primary refractory disease (no prior relapse but incomplete response to treatment) in BM as documented by histology and/or 123I-MIBG scan. Group 2 patients are in ≥2nd CR and at high risk for another relapse. Group 3 patients have secondary refractory disease (prior relapse and incomplete response to retrieval therapy) in BM as documented by histology and/or 123I-MIBG scan. Ph II: Groups 1 \& 3 pts can continue to get cycles every 1-2 months for up to 24 months from study enrollment or until they receive 5 cycles after a major response (CR or PR) is achieved. expansion phase II single arm trial Hu3F8 With GM-CSF Group 1 patients have primary refractory disease (no prior relapse but incomplete response to treatment) in BM as documented by histology and/or 123\^I-MIBG scan. Group 2 patients are in \>2nd CR/VGPR and at high risk for another relapse. Group 3 patients have secondary refractory disease (prior relapse and incomplete response to retrieval therapy) in BM as documented by histology and/or 123\^I-MIBG scan. GM-CSF can be omitted if patients have a history of an allergy to GM-CSF or develop an allergic reaction to GM-CSF after initiating therapy while on the protocol.
- Primary Outcome Measures
Name Time Method maximum tolerated dosage 1 year hu3F8 when combined with GM-CSF. DLT is defined after 1 cycle. Seventeen dosage levels of hu3F8 will be tested with three to six patients at each dosage level.
assess the toxicity 1 year of the humanized anti GD2 antibody hu3F8 when combined with Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) in patients with high risk neuroblastoma. All observed adverse events, regardless of treatment group or suspected causal relationship to study drug will be recorded. Adverse events will be identified and graded using the Common Toxicity Criteria Version 4.0
- Secondary Outcome Measures
Name Time Method pharmacokinetics of hu3F8 1 year (Phase I) when combined with GM-CSF. Pharmacokinetics will be measured by serial blood sampling following the first two iv doses of hu3F8 as listed in Table 3. Serum hu3F8 will be measured pre-infusion and at time pre- (within an hour before hu3F8), 5 min, 3h, 6-8h, 24h, 48h, 72h, 96, 120h, 168h 216h and 264h after the first infusion of hu3F8 during cycle1 and, whenever possible, peak hu3F8 level at pre- and \~5 minutes post-infusion will also be measured for each dose of hu3F8 in subsequent cycles .
assess activity of hu3F8 plus GM-CSF against HR-NB 2 years Another secondary objective is to assess the anti-tumor activity of hu3F8 against NB and other GD2-positive tumors. Anti-tumor activity will be measured by international neuroblastoma response criteria (INRC).
quantitate the response of marrow NB 1 year will be measured using quantitative Reverse transcription-PCR (qRTPCR) and its relationship with dosage of hu3F8 explored.
