简要总结
RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill more cancer cells.
PURPOSE: Phase I trial to study the effectiveness of interleukin-2 in treating children who have undergone bone marrow transplantation for acute myeloid leukemia.
详细描述
OBJECTIVES: I. Determine the maximum tolerated dose of interleukin-2 after autologous bone marrow transplantation in pediatric patients with acute myeloid leukemia. II. Determine toxic effects of this regimen in these patients.
OUTLINE: This is a dose escalation study. Patients receive interleukin-2 (IL-2) subcutaneously on days 1-7, 9-14, and 16-22. On days 8 and 15, patients receive IL-2 IV over 2 hours. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 6-9 patients receive escalating doses of IL-2 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 or 2 of 9 patients experience dose-limiting toxicity. Patients are followed every 6 months for 4 years and then annually thereafter.
PROJECTED ACCRUAL: A total of 6-27 patients will be accrued for this study.

研究组 & 干预措施
All patients
Day 1 through day 7, days 9-14 and days 16-22: The assigned dose of IL-2 will be administered SQ. On days 8 and 15, IL-2 will be administered as a 2 hour intravenous infusion of one million units/M2 of IL-2. After day 22 there will be a 7 day rest period before beginning the next cycle. The next cycle will repeat just as above. This will be repeated for a maximum of 4 total cycles of 21 days of IL-2 therapy. The maintenance dose of IL-2 will always be the same as given during cycle one, unless there is dose limiting toxicity.
干预措施: aldesleukin (Biological)
