Exatecan Mesylate in Treating Patients With Ewing's Sarcoma, Primitive Neuroectodermal Tumor, or Desmoplastic Small Round Cell Tumor

Sarcoma Clinical Trial

Official title: A Phase II Study Of Intravenous DX-8951f (EXATECAN MESYLATE) Administered Daily For Five Days Every Three Weeks To Pediatric And Young Adult Patients With Ewing's Sarcoma (ES), Primitive Neuroectodermal Tumor (PNET), Or Desmoplastic Small Round Cell Tumor (DSRCT)

Status Completed

Clinical Trial 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 patients who have relapsed or refractory Ewing's sarcoma or peripheral primitive neuroectodermal tumor or desmoplastic small round cell tumor.

Clinical Trial Description

OBJECTIVES:

• Determine the objective response rate in patients with Ewing's sarcoma, primitive neuroectodermal tumor, or desmoplastic small round cell tumor treated with exatecan mesylate.

• Determine the time to tumor progression in patients treated with this drug.

• Determine median survival and 6- and 12-month survival of patients treated with this drug.

• Determine the pain response in patients treated with this drug.

• Determine the qualitative and quantitative toxic effects of this drug in these patients.

• Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is an open-label, non-randomized, multicenter study. Patients are stratified according to disease (relapsed or refractory localized or metastatic Ewing's sarcoma or primitive neuroectodermal tumor vs desmoplastic small round cell tumor).

Patients receive exatecan mesylate IV over 30 minutes on days 1-5. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity for a maximum of 12 courses, or 6 courses beyond maximal response (whichever is longer).

Patients are followed every 3 months for 1 year after withdrawal from study.

PROJECTED ACCRUAL: A total of 13-27 patients will be accrued for stratum I within 12 months. A total of 9-17 patients will be accrued for stratum II within 15 months. ;
