Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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
- Patients must have MIBG-avid malignant CCT 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 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.
- Inability or unwillingness to comply with radiation safety procedures or protocol requirements.

- New York, New York
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
