A Phase 2a Study of Ultratrace™ Iobenguane I 131 in Patients With Relapsed/Refractory High-Risk Neuroblastoma
OBJECTIVES:
Primary
- To establish the maximum tolerated dose of iodine I 131 metaiodobenzylguanidine
(^131I-MIBG) in patients with relapsed/refractory high-risk neuroblastoma.
Secondary
- To describe toxicity following treatment with ^131I-MIBG in patients with
relapsed/refractory high-risk neuroblastoma.
- To estimate radiation absorbed doses to measurable lesions and to a standard set of
normal organs following a 0.1 mCi/kg [3.7 MBq/kg] (minimum dose of 1.0 mCi [37 MBq] but
not to exceed 5.0 mCi [185 MBq]) intravenous administration of ^131I-MIBG in patients
with relapsed/refractory high-risk neuroblastoma.
- To describe, within the confines of a phase IIa trial, objective tumor response
following treatment with ^131I-MIBG in patients with relapsed/refractory high-risk
neuroblastoma.
- To explore dose-response following treatment with ^131I-MIBG in patients with
relapsed/refractory high-risk neuroblastoma.
- To explore quality of life assessment following treatment with ^131I-MIBG in patients
with relapsed/refractory high-risk neuroblastoma.
OUTLINE:
- Dosimetry: Patients receive a dosimetric dose of iodine I 131 metaiodobenzylguanidine
(^131I-MIBG) IV over 1-3 minutes. Patients then undergo 2 or 3 MIBG scans within 5 days
of the dosimetry dose to assess biodistribution and tumor uptake. Patients with normal
tumor uptake and biodistribution proceed to treatment.
- Treatment: Within 1-4 weeks of the dosimetric dose, patients with normal tumor uptake
and biodistribution receive a therapeutic dose of ^131I-MIBG IV over 1 hour on day 0
and undergo MIBG scan on day 7. Patients then proceed to autologous stem cell infusion.
- Autologous stem cell infusion: Patients receive an infusion of autologous stem cells
from peripheral blood or bone marrow on day 14. Patients with an ANC of < 500/µl at any
point after autologous stem cell infusion receive filgrastim (G-CSF) IV or
subcutaneously once daily until ANC is > 2,000/µl.
Patients complete a quality of life questionnaire at baseline and then at day 60.
After completion of study treatment, patients are followed at day 60 and periodically
thereafter.
Interventional
Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Maximum tolerated dose
Dose limiting toxicity (DLT) is defined as any of the events (defined in Section 4.4 of the protocol) that are (possibly, probably or definitely) attributable to UltratraceTM iobenquane I 131. The MTD will be the highest dose tested at which fewer than one third of patients experience DLT when 6 patients have been treated at the MTD. If 6 patients are treated at the highest Dose Level, 4, and fewer than 2 patients experience a DLT, then the MTD will not be reached.
Each patient in a Dose Level cohort must be followed until time of DLT, to day 60 +/- 10 days or until engraftment which ever comes first before escalating to the next dose level
Yes
