About

RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill cancer cells.

PURPOSE: Phase I trial to study the effectiveness of interleukin-2 in treating patients with myelodysplastic syndrome.

Full description

OBJECTIVES:

• Determine the safety, tolerance, and maximum tolerated dose of subcutaneous interleukin-2 (aldesleukin; IL-2) in patients with myelodysplastic syndrome (MDS).
• Evaluate the hematologic effects of subcutaneous IL-2 in MDS.

OUTLINE: IL-2 will be administered in cycles of twice daily subcutaneous injections 7 days a week for 4 consecutive weeks. After each cycle the patient will be evaluated for response. The patient could continue IL-2 therapy for up to 12 cycles. There are 4 dose levels of IL-2. At each dose level 3 patients will be accrued sequentially.

Treatment with IL-2 should be continued until grade III toxicity or any side effects requiring hospitalization occurs. After the patient returns to baseline pretherapy values or grade I toxicity, the subject will resume IL-2 at 50% of the initial dose. If the patient again goes into grade III toxicity or is in need of hospitalization, IL-2 will be discontinued.

PROJECTED ACCRUAL: Between 12-24 patients will be accrued.

Enrollment: 24 patients

Ages: 15 to 120 years old
