Trial Summary

What is the purpose of this trial?The purpose of this study is to find out if an antibody called Humanized 3F8 (Hu3F8) combined with granulocyte- macrophage colony stimulating factor (GM-CSF) is safe for treating neuroblastoma.

Eligibility Criteria

This trial is for patients over 1 year old with high-risk neuroblastoma, which hasn't responded to standard treatments or has come back. They must have a certain number of white blood cells and not be allergic to mouse proteins. Pregnant or breastfeeding women can't join, nor can those with major organ problems (except hearing loss) or active severe infections.

Inclusion Criteria

I am older than 1 year.

My neuroblastoma is not responding to initial treatments or has come back.

I have had treatments with specific antibodies and do not have HAHA antibodies.

My major organs are functioning well, except possible hearing loss or blood issues.

I have tested positive for HAHA antibodies.

Participant Groups

The study tests the safety of combining an antibody called Hu3F8 with GM-CSF in treating neuroblastoma. It's looking at how well these two work together against cancer that's hard to treat or has returned after previous treatment.

Experimental Treatment

Group I: expansion phase II single arm trialExperimental Treatment1 Intervention

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.

Group II: Hu3F8 with GM-CSFExperimental Treatment1 Intervention

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.
