Brief Summary:

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

PURPOSE: Phase II trial to study the effectiveness of soblidotin in treating patients who have advanced or metastatic soft tissue sarcoma.

Condition or disease Intervention/treatment Phase
Sarcoma Drug: soblidotin Phase 2

Detailed Description:


  • Determine the objective tumor response rate in patients with advanced or metastatic soft tissue sarcoma with prior exposure to anthracycline-based chemotherapy when treated with soblidotin.
  • Determine the duration of response in patients treated with this drug.
  • Determine the time to tumor progression in patients treated with this drug.
  • Determine the median survival time and 12-month survival rate of patients treated with this drug.
  • Determine the quantitative and qualitative toxic effects of this drug in these patients.
  • Determine the pharmacokinetics of this drug in these patients.

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

Patients receive soblidotin IV over 1 hour on days 1 and 8. Treatment repeats every 3 weeks for at least 2 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for survival.

PROJECTED ACCRUAL: A total of 27 patients will be accrued for this study within 12 months.
