Combination Therapy of Antibody Hu3F8 With Granulocyte- Macrophage Colony Stimulating Factor (GM-CSF) in Patients With Relapsed/Refractory High-Risk Neuroblastoma
Neuroblastoma
About this trial
This is an interventional treatment trial for Neuroblastoma focused on measuring Bone Marrow, Hu3F8, GM-CSF, 12-230
Eligibility Criteria
Inclusion Criteria:
- 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.
- White blood cell count ≥1000/ul (phase I only)
- Absolute neutrophil count ≥500/ul (phase I only)
- Absolute lymphocyte count ≥500/ul (phase I only)
- Platelet count ≥25,000/ul (phase I only)
- No chemotherapy or immunotherapy for a minimum of three weeks prior to start of hu3F8
- Women of child-bearing potential must be willing to practice an effective method of birth control while on treatment
- Signed informed consent indicating awareness of the investigational nature of this program.
Exclusion Criteria:
- Existing major organ dysfunction > grade 2, with the exception of hearing loss and hematologic toxicity (defined as suppression of all subtypes of WBCs, RBCs, and platelets).
- Active life-threatening infection.
- Pregnant women or women who are breast-feeding.
- Inability to comply with protocol requirements, including PK studies and genetic studies (phase I only)
- History of allergy to mouse proteins.
- Positive human anti-hu3F8 antibody (HAHA) titer

Hu3F8 with GM-CSF
expansion phase II single arm trial
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.
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.
