Brief Summary: Phase I trial to compare the effectiveness of interleukin-12 with or without interleukin-2 in treating young patients who have refractory or recurrent neuroblastoma Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing Combining interleukin-2 with interleukin-12 may kill more tumor cells
Detailed Description: OBJECTIVES
I Define the maximum tolerated dose and dose-limiting toxicity of interleukin-12 with or without interleukin-2 in patients with refractory or recurrent neuroblastoma
II Determine preliminarily the antitumor effect of interleukin-12 with or without interleukin-2 in these patients
III Evaluate the immunoregulatory activity of interleukin-12 with or without interleukin-2 in these patients
IV Evaluate the antiangiogenic activity of interleukin-12 with or without interleukin-2 in these patients
OUTLINE This is a dose-escalation multicenter study Patients are assigned to 1 of 2 treatment cohorts
COHORT A Patients receive interleukin-12 IL-12 IV over 5-15 seconds on days 1 3 5 8 10 and 12
COHORT B Patients receive interleukin-2 IL-2 IV over 15 minutes twice daily on days 1 and 8 and IL-12 IV as in cohort A
Treatment in both cohorts repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity Some patients may receive additional courses at the discretion of the principal investigator
Cohorts of 3-6 patients in both cohorts receive escalating doses of IL-2 and IL-12 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
Once the MTD is determined an additional cohort of 8 patients receives IL-12 and IL-2 at the MTD
