| NCT00659984 | N2007-01: Ultratrace™ Iobenguane I 131 in Patients With Relapsed/Refractory High-Risk Neuroblastoma | PHASE2 | COMPLETED | 15 | — | — | Jun 1, 2008 | Nov 1, 2010 | Oct 4, 2017 | 8 | United States |
The maximum tolerated dose (MTD) was defined as the dose immediately below the level at which dose escalation would be stopped due to dose limiting toxicities (DLTs). Once the MTD was reached, an additional 3 patients were to be treated at that dose level, for a total of 6 patients at that planned dose level. DLTs were defined as any of the events that are possibly, probably or definitely attributable to UltratraceTM iobenguane I 131. The MTD was supposed to be the highest dose tested at which fewer than 1/3 of pts experience a DLT when 6 patients have been treated at the MTD but the dosimetry results indicated that the maximal dosage allowed to normal organs would be exceeded if the highest planned dose (21.0 mCi/kg) was administered, so the highest dose administered in the study was 18.6 mCi/kg .

| Ultratrace™ Iobenguane I 131 | EXPERIMENTAL | Eligible patients received a diagnostic imaging dose of Ultratrace™ Iobenguane I 131 (1-5 mCi) within 7 days of study enrollment, followed by three dosimetry scans over 3-6 days. If the imaging dose demonstrated normal biodistribution and tumor uptake, then the patient received a therapeutic dose within 7-28 days of the diagnostic imaging dose, followed by a single imaging scan on Day 7 post therapy. As per protocol, therapeutic dosing was to begin at 12.0 mCi/kg and escalate to 15.0, 18.0, and 21.0 mCi/kg until the MTD was established or the 21.0 mCi/kg dose level was reached. Actual doses administered ranged from 8.8 to 18.6 mCi/kg. Based on actual doses administered, patients were grouped into 3 mean dose groups: 11.2, 15.5, and 18.2 mCi/kg. The dosimetry dose was administered over a period of 1-3 minutes by injection; the therapeutic dose was diluted in up to 25 mL normal saline and infused intravenously over 30 to 60 minutes. |

| UltratraceTM Iobenguane I 131 Imaging | DRUG | 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. |
| UltratraceTM Iobenguane I 131 Therapy | DRUG | 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. |
Inclusion Criteria: * Patients must be at least one year and no more than 30 years of age when registered on this study. * Patients must have high risk neuroblastoma and either have tumor left after treatment started at diagnosis or have had the tumor grow back (relapsed) after getting some treatme...
