This is a compassionate use protocol to allow patients with advanced neuroblastoma palliative access to 131I-metaiodobenzylguanidine (131I-MIBG).
Condition or disease
Drug: Metaiodobenzylguanidine (MIBG)
Neuroblastoma remains a fatal disease for a large percentage of patients, especially those with high-risk disease features who become resistant to conventional therapy. 131I-metaiodobenzylguanidine (131I-MIBG) is a norepinephrine analog that concentrates in adrenergic tissue and therefore holds promise for cell-specific treatment of neuroblastoma. 131I-MIBG is active against relapsed or refractory neuroblastoma and associated hematopoietic toxicity can be abrogated with autologous stem cell rescue. 131I-MIBG given in doses of 10-18 millicurie (mCi)/kg with stem cell rescue, if necessary, is safe and effective palliative therapy for refractory or relapsed neuroblastoma patients.
131I-MIBG Therapeutic Administration. Therapeutic 131I-MIBG will be synthesized at Nuclear Diagnostic Products (NDP; Rockaway, New Jersey) with specific activities of 9-18 Ci/mmole. The therapeutic dose (8-18 mCi/kg at investigator's discretion; any dose greater than 12 requires stored stem cells) will be diluted in 25 ml of normal saline, and will be infused intravenously through a patient's central line, if already present, or a peripheral IV if a central line is not present over 120 minutes.

Layout table for eligibility information
Ages Eligible for Study:
1 Year and older (Child, Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Diagnosis: Refractory or relapsed neuroblastoma with original diagnosis based on tumor histopathology or elevated urine catecholamines with typical tumor cells in the bone marrow.
Age > 1 year and able to cooperate with radiation safety restrictions during therapy period.
Life Expectancy: greater than 6 weeks.
Lanksy and Karnofsky Performance Status: 60% or higher.
Disease status: Failure to respond to standard therapy (usually combination chemotherapy with or without radiation and surgery) or development of progressive disease at any time (any new lesion or an increase in size of >25% of a pre-existing lesion). Disease evaluable by MIBG scan must be present within 6 weeks of study entry and subsequent to any intervening therapy.
Stem cells: Patients must have an autologous hematopoietic stem cell product available for re-infusion after MIBG treatment at doses of >12 mCi/kg if needed. The minimum quantity for purged or unpurged peripheral blood stem cells is 1.0 x 106 cluster of differentiation 34 (CD34)+ cells/kg (optimum > 2 x 106 CD34+ cells/kg). The minimum dose for bone marrow is 1.0 x 108 mononuclear cells/kg (optimum > 2.0 x 108 mononuclear cells/kg). If no stem cells are available, then the dose of 131I-MIBG should be <12 mCi/kg .
Prior Therapy: Patients may enter this study with or without re-induction therapy for recurrent tumor. Patients must have fully recovered from the toxic effects of any prior therapy. At least 2 weeks should have elapsed since any anti-tumor therapy and the patient must meet hematologic criteria below. Three months should have elapsed in the case of completing radiation to any of the following fields: craniospinal, total abdominal, whole lung, total body irradiation). Cytokine therapy [eg granulocyte-colony stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-6 (IL-6), erythropoietin] must be discontinued a minimum or 24 hours prior to MIBG therapy. Prior 131I-MIBG therapy is allowed if > 6 months previous and if the patient has adequate hematopoietic stem cells available.
Liver function: bilirubin <2x normal and aspartate aminotransferase (AST)/Alanine aminotransferase (ALT) < 10x normal.
Kidney function: Creatinine less than or equal to 2
Hematopoietic Criteria Patients must have adequate hematopoietic function (without transfusion): absolute neutrophil count (ANC) >.750 x 10E9/L; Platelets >50 x 10E9/L if stem cells are not available; if stem cells are available, the patient should be independent of platelet transfusions with a platelet count of at least 20 x 10E9/L. Hemoglobin >10g/dl at time of treatment (transfusion allowed). Patients with granulocytopenia and/or thrombocytopenia due to tumor metastatic to the bone marrow may be eligible after discussion with study chair or designee.
Normal lung function as manifested by no dyspnea at rest or exercise intolerance, no oxygen requirement.
No clinically significant cardiac dysfunction
Signed informed consent: The patient and/or the patient's legally authorized guardian must acknowledge in writing that consent to become a study subject has been obtained, in accordance with institutional policies approved by the U.S. Department of Health and Human Services.
Patients with disease of any major organ system that would compromise their ability to withstand therapy. Any significant organ impairment should be discussed with the Study Chair or Vice Chair prior to patient entry.
Because of the teratogenic potential of the study medications, no patients who are pregnant or lactating will be allowed. Patients of childbearing potential must practice an effective method of birth control while participating on this study, to avoid possible pregnancy.
Patients who are on hemodialysis.
Patients with active infections that meet grade 3-4 toxicity criteria.
