BMS-247550 in Treating Women With Metastatic Breast Cancer

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 BMS-247550 in treating women who have stage IV or recurrent metastatic breast cancer.

OBJECTIVES:

* Determine the clinical activity of BMS-247550, in terms of tumor response rate, in women with taxane-resistant metastatic breast cancer.
* Determine the safety of this drug in these patients.
* Determine the duration of response, time to progression, and survival of patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive BMS-247550 IV over 3 hours on day 1. Treatment continues every 3 weeks for 4-18 courses in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 4 additional courses beyond CR. Responding patients may receive additional courses at the investigator's discretion.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 14-50 patients will be accrued for this study within 12 months.
