Irinotecan in Treating Patients With Newly Diagnosed Ewing’s Sarcoma


RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase II trial is studying how well irinotecan works in treating patients with newly diagnosed Ewing's sarcoma.

Full Title of Study: “Phase II Study of Irinotecan (CPT-11) in Children and Adolescents With High Risk Ewing’s Sarcoma”

Study Type

  • Study Type: Interventional
  • Study Design
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: September 2008

Detailed Description



- Assess the responsiveness of single-agent irinotecan hydrochloride in a patient population with newly diagnosed high-risk Ewing's sarcoma.

OUTLINE: This is an open-label, multicenter study.

Patients receive irinotecan hydrochloride IV over 1 hour on day 1. Treatment repeats every 21 days for 2 courses. After completion of 2 courses of therapy, patients may receive additional treatment at the discretion of the treating physician.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 35 patients will be accrued for this study.
