Using Iodine I 131 Metaiodobenzylguanidine to treat advanced neuroblastoma and pheochromocytoma

Official title: Open Access Protocol of Targeted Radiotherapy With I-metaiodobenzylguanidine (I-MIBG) in Patients With Resistant Neuroblastoma or Malignant Chromaffin Cell Tumors

Run by Memorial Sloan Kettering Cancer Center · NCT00107289 · Data updated 2026-11-12

This study is testing if a special treatment called Iodine I 131 Metaiodobenzylguanidine can help people with hard-to-treat neuroblastoma and pheochromocytoma feel better when other treatments haven’t worked.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients over one year old with recurrent or refractory neuroblastoma or malignant pheochromocytoma who have MIBG-avid tumors.

Probably not a fit

Patients with tumors that are not MIBG-avid or those who have not met the eligibility criteria may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness and safety of Iodine I 131 Metaiodobenzylguanidine (131 I-MIBG) in patients suffering from recurrent, progressive, or refractory neuroblastoma and malignant pheochromocytoma or paraganglioma. The study aims to determine how well this treatment works in patients whose tumors have not responded to standard therapies. Participants must have tumors that are MIBG-avid and evaluable on scans, and they must meet specific eligibility criteria regarding prior treatments and age. The trial is being conducted at the Memorial Sloan Kettering Cancer Center, a leading institution in cancer treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat neuroblastoma and pheochromocytoma.

How similar studies have gone: Other studies have shown promising results with similar approaches using I-131 MIBG for treating neuroblastoma, indicating potential for success.

Inclusion criteria for NB:

* Patients must have the diagnosis of NB in accordance with the International Criteria, i.e., either histopathology (confirmed by the MSKCC Department of Pathology) or BM involvement plus elevated urinary catecholamines.
* Must have a history of tumor progression or recurrence or failure to achieve complete response with standard therapy.
* Patients must have MIBG-avid NB and evaluable disease on MIBG scan at time of enrollment on protocol
* Prior Therapy: At least 2 weeks should have elapsed since any biologic therapy. Three weeks should have elapsed since last dose of chemotherapy.
* Age \>1 year
* Determination that radiation safety restrictions during therapy period can be implemented.
* Stem cells: Patients for high does must have an autologous hematopoietic stem cell product cryopreserved and available for re-infusion after MIBG treatment. Patients for low dose do not require cryopreserved autologous hematopoietic stem cell product available. The minimum dose for peripheral blood stem cells is 2 X106 CD34+ cells/kg.
* Minimum life expectancy of eight weeks
* Signed informed consent indicating awareness of the investigational nature of this program.

Inclusion criteria for malignant CCT:

* Patients must have the diagnosis of malignant CCT i.e. malignant pheochromocytoma or malignant paraganglioma

* Prior Therapy: At least 2 weeks should have elapsed since any biologic therapy. Three weeks should have elapsed since last dose of chemotherapy.
* Age between 1 and 21 years and able to cooperate with radiation safety restrictions during therapy period
* Stem cells: Patients must have an autologous hematopoietic stem cell product cryopreserved and available for re-infusion after MIBG treatment. The minimum dose for peripheral blood stem cells is 2 X106 CD34+ cells/kg.
* Minimum life expectancy of eight weeks.
* Signed informed consent indicating awareness of the investigational nature of this program.

Exclusion Criteria:

* Severe major organ toxicity. Specifically, renal, cardiac, hepatic, pulmonary, gastrointestinal and neurologic toxicity should all be grade 2 or less. A grade 3 hearing deficit is acceptable.
* Active serious infections not controlled by antibiotics.
* Pregnant women are excluded for fear of danger to the fetus. Therefore negative pregnancy test is required for all women of child-bearing age, and appropriate contraception is used during the study period.
