A Phase 1 interventional study of irinotecan hydrochloride and vincristine sulfate in Neuroblastoma, sponsored by New Approaches to Neuroblastoma Therapy Consortium. Completed at 12 sites in United States. Open to participants aged 1 Year to 30 Years. Per ClinicalTrials.gov, last updated 2026-04-14.

RATIONALE: Radioactive drugs, such as iodine I 131 metaiodobenzylguanidine (MIGB), may carry radiation directly to tumor cells and not harm normal cells. Drugs used in chemotherapy, such as irinotecan and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving iodine I 131 MIGB together with irinotecan and vincristine may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of iodine I 131 MIGB when given together with irinotecan and vincristine in treating young patients with resistant or relapsed high-risk neuroblastoma.
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a multicenter, dose-escalation study of iodine I 131 metaiodobenzylguanidine (\^131I-MIBG).
Patients receive \^131I-MIBG IV over 1½-2 hours on day 1, vincristine IV on days 0 and 7, and irinotecan hydrochloride IV over 1 hour on days 0-4 and 7-11. Treatment repeats every 56 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months thereafter.
625 studies on the registry are indexed under Neuroblastoma; 122 are open to participants now.
This study's enrollment of 26 is below the median of 32 across 475 interventional studies indexed under Neuroblastoma.

DISEASE CHARACTERISTICS:
Inclusion criteria:
Must have high-risk neuroblastoma AND meets at least one of the following criteria:
Recurrent or progressive disease at any time
Refractory disease (i.e., less than a partial response to frontline therapy, including a minimum of 4 courses of chemotherapy)
Persistent disease after at least a partial response to frontline therapy (i.e., patient still has residual disease by MIBG scan, CT/MRI scan, or bone marrow)
Must have autologous hematopoietic stem cell product available and it must be free of tumor cell contamination (0 tumor cells /1,000,000 nucleated cells), cryopreserved, and available for re-infusion after \^131I-MIBG treatment, if immunocytology has been performed on the stem cell product

To determine the maximum tolerated dose (MTD) of 131I-MIBG given in combination with fixed-dose irinotecan/vincristine to children with high-risk refractory/relapsed neuroblastoma.
Time frame: Tolerability will be assessed throughout the study.
To determine the dose limiting toxicities of 131I-MIBG combined with irinotecan/vincristine.
Time frame: Adverse events, clinically significant changes in laboratory results, and vital signs, to be measured throughout the study.
Within the confines of a Phase I study, to determine if there is a therapeutic response to this regimen.
Disease response will be evaluated by any of the following CT, MRI, MIBG, Bone Marrow, Urine Catecholamines at baseline, prior to each cycle and at the end of treatment.
Time frame: Disease response will be evaluated at baseline, prior to each cycle and at the end of treatment.
