RATIONALE: Inserting the gene for interleukin-2 into a person's neuroblastoma cells may make the body build an immune response and kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of using interleukin-2 gene-modified neuroblastoma cells in treating children who have relapsed or refractory neuroblastoma.

Study summary:

OBJECTIVES: I. Assess in patients with neuroblastoma the safety of up to four subcutaneous injections of autologous neuroblastoma cells that have been modified by insertion of the interleukin-2 (IL-2) gene introduced by an adenoviral vector. II. Determine whether major histocompatibility complex restricted or unrestricted antitumor immune responses are induced by treatment with IL-2 gene modified autologous neuroblasts. III. Determine the dose of IL-2 gene modified autologous neuroblasts needed to achieve antitumor responses in these patients. IV. Obtain preliminary data on the antitumor effects of this regimen in these patients. V. Determine the maximum tolerated dose of this regimen in these patients. OUTLINE: This is a dose escalation study. Autologous neuroblastoma cells are modified by insertion of the interleukin-2 (IL-2) gene introduced by an adenoviral vector. Patients receive IL-2 gene modified autologous neuroblastoma cells subcutaneously on days 1 and 8 followed by 3-4 weeks of rest. Patients with complete or partial response or stable disease may receive one additional course consisting of 2 additional injections separated by 1 week at the dose level previously administered on day 8 of course 1. Patients with progressive disease are taken off study. Cohorts of 3-6 patients receive escalating doses of IL-2 gene modified autologous neuroblastoma cells until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicity. Patients are followed every other week for 6 weeks, monthly for 1 year, and then annually for 10 years. PROJECTED ACCRUAL: A total of 15-24 patients will be accrued for this study over 2.5-4 years.
