- 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.
- 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.
Who cannot join
- 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.

About this study
Official title: Open Access Protocol of Targeted Radiotherapy With I-metaiodobenzylguanidine (I-MIBG) in Patients With Resistant Neuroblastoma or Malignant Chromaffin Cell Tumors
The purpose of this research study is to find how active and safe 131 I-MIBG is in patients with resistant neuroblastoma, malignant pheochromocytoma and malignant paraganglioma.
- Conditions
- Neuroblastoma, Pheochromocytoma
- Being tested
- iobenguane I 131

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
iobenguane I 131Drug
A single dose of iodine I 131 metaiodobenzylguanidine (^131I-MIBG) IV over 30 minutes to 4 hours or for 15 minutes for smaller patients on day 0. Patients undergo radiation dosimetry following the first dose of ^131I-MIBG to determine if a second dose can be safely administered. Some patients may receive a second dose of iodine I 131 metaiodobenzylguanidine (^131I-MIBG) 6-8 weeks after the first dose. In some scenarios, extended time will be allowed before the second dose of 131I-MIBG for additional recovery and possible bridging therapy. If response is achieved and patients do not experience major toxicity. After blood radioactivity has fallen below 1 μCi/mL, patients may undergo autologous stem cell transplantation. After completion of study treatment, patients are followed at 4-6 weeks after ^131I-MIBG administration and then every 3 months for up to 1 year. Once patients are off treatment on this protocol, they will begin long term follow up through 5 years from enrollment.
| Study group | Role | What they receive |
|---|---|---|
| Radiation | Experimental | Patients will be treated with IV 131I-MIBG using 1-2 high dose(s) or up to 16 low doses.
Thyroid protection is commenced seven days (+/-2 days) prior to administration of 131I-MIBG and continued for up to 42 days after each 131I-MIBG treatment. Given that this is an open access protocol, re-enrollment is allowed per PI discretion. Patients who received this treatment previously are allowed to be re-enrolled if they meet the eligibility criteria. Re-enrollment can be to the same arm previously treated on (high dose versus low dose) or to the other arm. Patients will not be eligible for re-enrollment if they have already received 16 low doses or 4 high doses of 131I-MIBG. Receives: Drug: iobenguane I 131 |

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing iobenguane I 131 in people with Neuroblastoma and Pheochromocytoma, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 16 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ellen Basu, MD, PhD (212-639-5204), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Response (complete or partial) (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00107289, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2026.
