Alternate Title

Double Infusion of Iodine I 131 Metaiodobenzylguanidine Followed by Autologous Stem Cell Transplantation in Treating Patients With Refractory Neuroblastoma

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase I	Treatment	Completed	1 to 30	NCI	NANT-2000-01 NCT00083135

Objectives

Primary

1. Determine the maximum tolerated red marrow radiation dose delivered and associated toxic effects of escalating activity of iodine I 131 metaiodobenzylguanidine (¹³¹I-MIBG) followed by autologous hematopoietic stem cell transplantation in patients with refractory neuroblastoma.
2. Determine the number of days after stem cell transplantation to achieve absolute neutrophil count ≥ 500/mm³ for 3 days and platelet count ≥ 20,000/mm³ for 3 days (without transfusions) in patients treated with this regimen.

Secondary

1. Determine the response rate in patients treated with this regimen, based on lesions measurable by CT or MRI at study entry, patients with ¹³¹I-MIBG scan-positive lesions only, and patients with minimal residual tumor in bone marrow who have complete response by immunocytology and morphology.
2. Determine the tumor absorbed radiation dose in patients with measurable soft tissue lesions treated with this regimen.
3. Correlate, if possible, TP53 mutations with response in patients with accessible bone marrow tumor treated with ¹³¹I-MIBG.

Entry Criteria

Disease Characteristics:

• Diagnosis of neuroblastoma
  • Confirmed by at least 1 of the following methods:
    • Histology
    • Clumps of tumor cells in bone marrow with elevated urinary catecholamine metabolites
  • High-risk disease
    • Poor response to induction therapy OR relapse defined by any of the following:
      • No response, stable disease, or mixed response after a minimum of 3 prior courses of chemotherapy
      • More than 100 tumor cells per 10⁵ nucleated cells on bone marrow immunocytology after at least 3 prior courses of chemotherapy
      • Progressive disease at any time during or after therapy
      • Patients with massive bone marrow invasion (more than 50% replacement of bone marrow by tumor cells) are allowed
• Must have positive iodine I 131 metaiodobenzylguanidine (¹³¹I-MIBG) within the past 6 weeks or subsequent to any other prior antitumor therapy delivered within the past 6 weeks
• Must meet the following criteria for minimum number of autologous stem cells:
  • Unpurged peripheral blood stem cells (PBSC)
    • Minimum of 1,500,000/mm³ CD34-positive cells/kg
    • Collected products must have < 1 tumor cell/100,000 normal cells by immunocytology
  • PBSC purged with immunomagnetic beads
    • Minimum of 1,000,000/mm³ viable CD34-positive cells/kg
    • Collected products must have < 1 tumor cell/100,000 normal cells by immunocytology
  • CD34-positive selected PBSC products are not allowed
  • Patients who had PBSC collected previously with no immunocytological testing available may use those products provided bone marrow is tumor free by bilateral bone marrow aspirate AND biopsy for morphology is performed within 4 weeks before PBSC collection
  • Patients with no tumor involvement in bone marrow at diagnosis and PBSC collection before any disease progression do not require documentation of negative bone marrow morphology

Prior/Concurrent Therapy:

Biologic therapy

• At least 2 weeks since prior biologic or other non-myelosuppressive therapy

Endocrine therapy

• Not specified

Radiotherapy

• See Disease Characteristics
• At least 6 months since prior craniospinal, total abdominal, or whole lung radiotherapy
• At least 2 weeks since prior radiotherapy to any site
• No prior total body irradiation
• No prior radiotherapy to > 25% of bone marrow
• No prior ¹³¹I-MIBG

Surgery

• Not specified

Other

• Recovered from all prior therapy
• Concurrent antifungal therapy allowed provided culture and biopsy are negative in suspected radiographic lesions
• Prior re-induction therapy for recurrent tumor allowed
• No concurrent antiretroviral therapy for HIV-positive patients

Hematopoietic

• Absolute neutrophil count ≥ 500/mm³
• Platelet count ≥ 50,000/mm³ (without transfusion)

• Fertile patients must use effective contraception
• Able to cooperate physically and psychologically with radiation isolation
• No disease of any major organ system that would preclude study participation
• No active infection requiring antivirals, antibiotics, or antifungals
• No weight that would require exceeding a maximum total allowable dose of ¹³¹I-MIBG

Expected Enrollment

A total of 9-18 patients will be accrued for this study within 2 years.

Outline

This is a dose-escalation, multicenter study.

• Iodine I 131 metaiodobenzylguanidine (¹³¹I-MIBG) therapy: Patients receive¹³¹I-MIBG IV over 2 hours on days 0 and 14.

  Cohorts of 3-6 patients receive escalating doses of ¹³¹I-MIBG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

• Stem cell transplantation therapy: Patients undergo autologous peripheral blood stem cell transplantation on day 28. Patients receive filgrastim (G-CSF) IV over 1 hour OR subcutaneously daily beginning on day 28 and continuing until blood counts recover.

Patients are followed every 3 months for 1 year and then annually thereafter.
