Alternate Title

Bortezomib in Treating Patients With Advanced or Metastatic Sarcoma

Basic Trial Information

Objectives

1. Determine the response rate in patients with advanced or metastatic sarcoma treated with bortezomib.
2. Correlate levels of cyclins D1, E, p21 (WAF1), p27 (Kip1), mdm², p53, and Ki67 with response in patients treated with this drug.

Expected Enrollment

A total of 21-41 patients will be accrued for stratum I within 5-11 months and 21-41 patients will be accrued for stratum II within 10.5-22 months. (Stratum I closed to accrual as of 10/17/03.)

Outline

This is an open-label, multicenter study. Patients are stratified according to disease (stratum I: soft tissue sarcoma not specified in stratum II, osteogenic sarcoma arising from soft tissues, or gastrointestinal stromal tumor vs stratum II: Ewing's sarcoma of soft tissue or bone, rhabdomyosarcoma, or osteogenic sarcoma of bone). (Stratum I closed to accrual as of 10/17/03.)

Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 1 year.
