Brief Summary:

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of exatecan mesylate in treating children who have relapsed or refractory rhabdomyosarcoma.

Condition or disease Intervention/treatment Phase
Sarcoma Drug: exatecan mesylate Phase 2

Detailed Description:


  • Determine the objective response rate (complete and partial responses) in pediatric patients with relapsed or refractory rhabdomyosarcoma treated with exatecan mesylate.
  • Determine the time to tumor progression in patients treated with this drug.
  • Determine the median survival and survival at 6 and 12 months in patients treated with this drug.
  • Assess pain in patients treated with this drug.
  • Evaluate the quantitative and qualitative toxic effects of this drug in these patients.
  • Evaluate the pharmacokinetics of this drug in these patients.

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

Patients receive exatecan mesylate IV over 30 minutes on days 1-5. Treatment repeats every 3 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) receive 6 additional courses beyond CR.

PROJECTED ACCRUAL: A total of 13-27 patients will be accrued for this study within 1 year.
