Brief summary:
This phase II trial is studying how well giving trastuzumab together with ixabepilone and carboplatin works in treating patients with HER2/neu-positive metastatic breast cancer. Monoclonal antibodies, such as trastuzumab, can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as ixabepilone and carboplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining trastuzumab with ixabepilone and carboplatin may kill more tumor cells.

Detailed description:
PRIMARY OBJECTIVES:

I. To determine the response rate (as determined by RECIST criteria) to combination therapy with Ixabepilone (BMS-247550), trastuzumab, and carboplatin in patients with metastatic breast cancer known to overexpress HER2.

SECONDARY OBJECTIVES:

I. To determine time to disease progression (TTP) and time to treatment failure (TTF) after treatment with Ixabepilone (BMS-247550), trastuzumab and carboplatin in patients with metastatic breast cancer known to overexpress HER2.

II. To determine the toxicity of combination therapy with Ixabepilone (BMS-247550), trastuzumab and carboplatin in patients with metastatic breast cancer known to overexpress HER2.

III. To evaluate overall survival (OS) of combination therapy with Ixabepilone (BMS-247550), trastuzumab, and carboplatin in patients with metastatic breast cancer known to overexpress HER2.

IV. To correlate levels of phospho-STAT3 with levels of HER2, Survivin and EGFR expression as measured in tissue by immunohistochemistry.

OUTLINE: This is a multicenter study.

Induction therapy: Patients receive trastuzumab (Herceptin®) IV over 30 minutes\* on days 1, 8, 15, and 22 and ixabepilone IV over 1 hour and carboplatin IV over 1 hour on days 1, 8, and 15. Treatment repeats every 28 days for up to 6 courses in the absence of unacceptable toxicity.

NOTE: \*Trastuzumab is given over 90 minutes on day 1 of course 1 (induction therapy) only.

Maintenance therapy: Patients receive trastuzumab IV over 90 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years and then every 6 months for 3 years from study entry.

PROJECTED ACCRUAL: A total of 10-60 patients will be accrued for this study within 1-6 months.
