A Phase 2a Study of Ultratrace™ Iobenguane I 131 in Patients With Relapsed/Refractory High-Risk Neuroblastoma
In Brief
A Phase 2 clinical trial evaluating UltratraceTM Iobenguane I 131 Imaging and UltratraceTM Iobenguane I 131 Therapy for Neuroblastoma. Completed, enrolled 15 participants across 8 sites.
Detailed Summary
RATIONALE: Radioactive drugs, such as iodine I 131 metaiodobenzylguanidine (MIBG), may carry radiation directly to tumor cells and not harm normal cells. A bone marrow or peripheral stem cell transplant using stem cells from the patient may be able to replace blood-forming cells that were destroyed by I 131 MIBG. PURPOSE: This phase II trial is studying the side effects and best dose of iodine I 131 MIBG followed by a stem cell transplant in treating young patients with relapsed or refractory high-risk neuroblastoma.

Timeline
Interventions
0.1 mCi/kg \[3.7 MBq/kg\] (minimum dose 1mCi \[37MBq\] but not to exceed 5 mCi \[185 MBq\]) of UltratraceTM Iobenguane I 131 given 7 -28 days before therapeutic dose administration on day 0. Thyroid protection will be administered per institutional protocol for I-131-MIBG however, thyroid blocking must be started prior to the Ultratrace imaging dose. Anterior and posterior whole body images will be taken to assess organ distribution, tumor uptake and dosimetry calculations.
Therapeutic dose will be given on Day 0 if dosimetry scans showed that the prescribed or adjusted dose will not exceed \> 23 Gy to the kidneys, \> 30 Gy to the liver, or \> 15 Gy to the lungs. and tumor uptake confirmed with UltratraceTM imaging dose. Only one treatment course of therapeutic UltratraceTM will be given in this study.
