131I-Metaiodobenzylguanidine (131I-MIBG) Therapy for Relapsed/Refractory Neuroblastoma
Relapsed NeuroblastomaMetastatic PheochromocytomaThis expanded access is the best available therapy/compassionate use designed to determine the palliative benefit and toxicity of 131I-MIBG in patients with relapsed/refractory neuroblastoma or metastatic pheochromocytoma who are not eligible for therapies of higher priority. Patients may receive a range of doses depending on stem cell availability and tumor involvement of bone marrow. Response rate, toxicity, and time to progression and death will be evaluated.
