Secondary Outcome Measures:
  • Progression-free survival at 6 months [ Designated as safety issue: No ]

Estimated Enrollment: 40
Study Start Date: June 2002
Study Completion Date: June 2007
Primary Completion Date: June 2007 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the effectiveness of imatinib mesylate in patients with recurrent Ewing's family of tumors or desmoplastic small round-cell tumor.
  • Determine the toxic effects of this drug in these patients.
  • Determine the duration of disease-free and overall survival of patients treated with this drug.

OUTLINE: This is an open-label study.

Patients receive oral imatinib mesylate twice daily on days 1-28. Courses repeat every 28 days.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study.
