Summary

131I-Metaiodobenzylguanidine (131I-MIBG) is one of the most effective therapies utilized for
neuroblastoma patients with refractory or relapsed disease. In this pediatric phase 1 trial,
131I-MIBG will be given in combination with dinutuximab, a chimeric 14.18 monoclonal
antibody. This study will utilize a traditional Phase I rolling 6 dose escalation design to
determine a recommended phase 2 pediatric dose. An expansion cohort of an additional 6
patients will then be enrolled. If tolerable, vorinostat will then be added to the third dose
level. A 6 patient expansion cohort may then be enrolled.

Objectives

131I-Metaiodobenzylguanidine (131I-MIBG) is one of the most effective therapies utilized for
neuroblastoma patients with refractory or relapsed disease. Data from pre-clinical and adult
studies suggest that radiation can enhance the efficacy of immunotherapy and targeted
therapies such as dinutuximab. This first pediatric phase 1 trial of 131I-MIBG in combination
with dinutuximab and vorinostat aims to determine the recommended phase 2 pediatric dose of
these three therapies in combination.

Eligibility

  1. Patients must have evidence of MIBG uptake into tumor at = 1 site (bone or soft tissue) within 28 days prior to study entry and subsequent to any intervening therapy.
  2. Patients must have a diagnosis of neuroblastoma either by histologic verification of neuroblastoma and/or demonstration of tumor cells in the bone marrow with increased urinary catecholamines.
  3. Patients must have a history of high-risk neuroblastoma according to COG risk classification at the time of study registration. Patients who were initially considered low or intermediate-risk, but then reclassified as high-risk are also eligible.
  4. All patients must have at least one of the following
  5. Recurrent/progressive disease: after the diagnosis of high risk neuroblastoma at any time prior to enrollment regardless of response to frontline therapy
  6. No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma b1) Refractory disease- a best overall response of no response/stable disease since diagnosis of high risk neuroblastoma and at least 4 cycles of induction therapy. No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma. b2) Persistent disease- a best overall response of no partial response since diagnosis of high risk neuroblastoma and at least 4 cycles of induction therapy. No prior history of recurrent/progressive disease since the diagnosis of high risk neuroblastoma.
  7. Patients must have at least ONE of the following (lesions may have received prior radiation therapy as long as they meet the other criteria listed below): a) For recurrent/progressive or refractory disease, at least one MIBG avid bone site. b) For persistent disease, if a patient has 3 or more MIBG avid lesions, then no biopsy is required. If a patients has only 1 or 2 MIBG avid bone lesion sites then biopsy confirmation of neuroblastoma or ganglioneuroblastoma in at least one MIBG avid site present at the time of enrollment is required to be obtained at any time point prior to enrollment. c) For MIBG non-avid tumors, patients must have at least one FDG avid site and a biopsy confirmation of neuroblastoma and/or ganglioneuroblastoma at any time prior to enrollment from at least one FDG-avid site.
  8. Any amount of neuroblastoma tumor cells in the bone marrow done at the time of study enrollment based on routine morphology with or without immunocytochemistry in at least one sample from bilateral aspirates and biopsies.
  9. At least one soft tissue lesion that meets criteria for a TARGET lesion as defined by: a) SIZE: Lesion can be accurately measured in at least one dimension with a longest diameter = 10 mm, or for lymph nodes = 15 mm on short axis. Lesions meeting size criteria will be considered measurable. b) In addition to size, a lesion needs to meet one of the following criteria except for patients with parenchymal CNS lesions which only need to meet size criteria: b1) MIBG avid. For patients with recurrent/progressive or refractory disease, no biopsy is required. For patients with persistent disease only: If a patient has only 1 or 2 MIBG avid lesions sites, then biopsy confirmation of neuroblastoma and/or ganglioneuroblastoma in at least one MIBG avid site present at time of enrollment is required to be obtained. If a patient has 3 or more MIBG avid lesions, then no biopsy is required. b2) MIBG non avid tumors: Patients must have at least one FDG avid site and biopsy confirmation of neuroblastoma and/or ganglioneuroblastoma in at least one FDG-PET avid site present at the time of enrollment.
  10. At least one non-target soft tissue lesion that is not measurable, but had a biopsy positive for neuroblastoma and/or ganglioneuroblastoma or is MIBG avid at any time prior to enrollment.
  11. Patients must have a life expectancy of at least 12 weeks and a Lansky (=16 years) or Karnofsky (>16 years) score of at least 50.
  12. Prior Therapy 1. Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to study registration.
  13. Patients must not have received the therapies indicated below after disease evaluation or within the specified time period prior to registration on this study as follows:
  14. Myelosuppressive chemotherapy: must not have received within 2 weeks prior to registration.
  15. Biologic anti-neoplastics- agents not known to be associated with reduced platelet or ANC counts (including retinoids): must not have received within 7 days prior to registration.
  16. Monoclonal antibodies: must have received last dose at least 7 days or 3 half-lives whichever is longer, but no longer than 30 days (with recovery of any associated toxicities), prior to protocol therapy.
  17. Cellular Therapy (e.g. modified T cells, NK cells, dentritic cells etc.): must not have received within 3 weeks and resolution of all toxicities.
  18. Radiation: must not have received small port radiation within 7 days prior to registration.
