Iodobenzylguanidine Meta-I131 and Topotecan in Young Patients With Refractory or Relapsed Metastatic Neuroblastoma

Phase 2
Completed
Conditions
Neuroblastoma
Interventions
Procedure: Autologous hematopoietic stem cell transplantation
Radiation: iobenguane I 131
Radiation: total-body irradiation
Registration Number
NCT00960739
Lead Sponsor
Centre Oscar Lambret
Brief Summary

RATIONALE: Radioactive drugs, such as iodobenzylguanidine meta-I131, may carry radiation directly to tumor cells and not harm normal cells. Drugs used in chemotherapy, such as topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. A stem cell transplant may be able to replace the cells that were destroyed by iodobenzylguanidine meta-i131 and topotecan hydrochloride.

PURPOSE: This phase II trial is studying the side effects of iodobenzylguanidine meta-I131 given together with topotecan hydrochloride and to see how well it works in treating young patients with refractory or relapsed metastatic neuroblastoma.

Detailed Description

OBJECTIVES:

Primary

* Determine the antitumor activity of iodobenzylguanidine meta-I131 (\^131I-MIBG) and topotecan in young patients with refractory or relapsed metastatic neuroblastoma.

Secondary

* Determine the hematological and extra-hematological toxicities of this regimen.

OUTLINE: This is a multicenter study.

During the 21 days before treatment begins, autologous peripheral blood stem cells (PBSC) are collected.

Patients receive topotecan hydrochloride IV over 30 minutes daily on days 1-5 and iodobenzylguanidine meta-\^131I IV over 2 hours on day 1. Treatment repeats every 21 days for 2 courses. Patients also undergo total-body irradiation.

On day 10 of the second course, autologous PBSC are reinfused.

After completion of study therapy, patients are followed at 6 and 12 months.
