Study Description
Brief Summary:

This is a multi-center, single arm trial of two doses of 18 mCi/kg of Ultratrace iobenguane I 131 administered to subjects with high-risk neuroblastoma. Iobenguane I 131 is a drug that has already been used in many children to treat neuroblastoma, and it is known to shrink some of the tumors, and cause manageable side effects. When administered intravenously, Iobenguane I 131 accumulates in the neuroblastoma cancer cells and causes them to die.

In this study the investigators are investigating the use of a new form of Iobenguane I 131 called Ultratrace iobenguane I 131. This form is expected to deliver higher amounts of radioactive I 131 to the neuroblastoma cells. The primary purpose of the study is to determine if Ultratrace iobenguane I 131 can be used to successfully treat high-risk neuroblastoma. The study will also assess the safety of Ultratrace iobenguane I 131 when given to patients with high-risk neuroblastoma.

Arms and Interventions

Arm Intervention/treatment
Experimental: Ultratrace Iobenguane I 131 Drug: Ultratrace Iobenguane I 131
Subjects will receive an Imaging Dose of 0.1 mCi/kg [3.7 MBq/kg] (a minimum dose of 1.0 mCi [37 MBq] but not to exceed 5.0 mCi [185 MBq]) of Ultratrace iobenguane I 131 to have dosimetry performed and to confirm tumor uptake of the test article prior to receiving each of 2 planned Therapeutic Doses of Ultratrace iobeneguane I 131 . Within 28 days of screening, eligible subjects (as confirmed by the first Imaging dose study)will receive an Ultratrace iobenguane I 131 Therapeutic dose of of 15.0 - 18.0 mCi/kg (max. 666 MBq/kg) followed by imaging 7 days later or upon discharge from radiation isolation. A second Therapeutic Dose (preceded by a repeat Image Dose and dosimetry study)and imaging upon discharge from radiation isolation will be repeated approximately 8 weeks after the first dose.

Outcome Measures

Primary Outcome Measures :
  1. Proportion of patients with complete or partial response, sustained over two assessments, following treatment. Response criteria for the primary endpoint are based on the International Neuroblastoma Response Criteria (INRC). [ Time Frame: Weeks 8, 16, 26, 39 and 52 after treatment ]

Secondary Outcome Measures :
  1. Change in use of narcotics for pain management [ Time Frame: Weeks 8, 16, 26, 39 and 52 after treatment ]
  2. Change in patient quality of life [ Time Frame: Weeks 8, 16, 26, 39 and 52 after treatment ]
  3. Change in key tumor markers (HVA and VMA) [ Time Frame: Weeks 8, 16, 26, 39 and 52 after treatment ]
  4. Overall survival [ Time Frame: Weeks 8, 16, 26, 39 and 52 after treatment ]

Ages Eligible for Study:   12 Months and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Patients must meet all of the following inclusion criteria:

  1. Males or females who are >12 months of age
  2. Have a diagnosis of neuroblastoma either by (a) histologic verification of neuroblastoma and/or (b) demonstration of tumor cells in the bone marrow with increased urinary catecholamine metabolites
  3. Have high-risk neuroblastoma with relapsed/refractory disease at any time.
  4. MIBG avid disease demonstrated by 131I or 123I -MIBG uptake into tumor at ≥ one site within 28 days prior to study treatment and no intervention/therapy between the time of the MIBG scan and study treatment.
  5. To be eligible to receive at least one therapeutic dose, patients must have adequate banked autologous stem cells defined as:

    PBSC: A minimum of 2.0 x 106 viable CD34+ cells/kg (purged or unpurged) (see Section 10.4.15)

  6. Prior Therapy:

    1. Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study. There is no limitation on the number of prior chemotherapeutic regimens that the patient may have received.
    2. The last dose of all local palliative radiation must be ≥ 14 days prior to the first therapeutic dose of Ultratrace iobenguane I 131. Any lesion treated with local palliative radiation during this period can not be included in the baseline target lesion evaluation.
    3. The last dose of all local palliative radiation to more than 25% of marrow containing bones must be ≥ 28 days prior to the first therapeutic dose of Ultratrace iobenguane I 131. A minimum of 3 months is required following prior large field radiation therapy (i.e. craniospinal therapy, total lung, > 50% marrow space). Note: Radiation therapy of focal skull-based bony metastatic disease (only) is not considered craniospinal therapy.
