Brief Summary:

This study is for women and men who have previously treated metastatic (has spread to other parts in the body), Her2- positive breast cancer. The purpose of this study is to find out what effects (good and bad) the FDA-approved drugs etoposide and trastuzumab have on this type of breast cancer and to determine if these drugs are safe to use together. This research is being done to find more effective treatment for this type of condition.

In this study, trastuzumab and etoposide will be given by intravenous infusion (IV; through a vein) on the first 3 days of every 3-week cycle. This is repeated for 6 cycles. After 6 cycles, only trastuzumab will be given until worsening of disease. In this study, a small amount of your tissue that was collected when you had surgery will be evaluated in the lab to look at genetic differences among people and how those differences may affect a response to a specific drug or medicine. This testing will look for a gene called Top2A. Previous studies suggest that people who have both the Top2A and Her2 genes respond to certain chemotherapies (anti-cancer drugs) differently from those who only have the Her2 gene.

Intervention Details:
    Drug: Etoposide
    etoposide 100 mg/m2 daily for 3 days every three weeks for 6 cycles
    Other Names:
    • Eposin
    • Etopophos
    • Vepesid
    • VP-16
    Drug: Trastuzumab
    intravenous trastuzumab 8 mg/kg loading dose and then 6 mg/kg every three weeks and then single agent trastuzumab until progression of disease
    Other Name: Herceptin

Primary Outcome Measures :
  1. To determine efficacy of trastuzumab combined with etoposide in patients with HER2-positive metastatic breast cancer, and to assess toxicity of the combination of trastuzumab with intravenous etoposide. [ Time Frame: quarterly ]

Secondary Outcome Measures :
  1. To explore relationship of amplification or deletion of the TOP2A gene to efficacy of trastuzumab combined with etoposide in patients with HER2 positive metastatic breast cancer. [ Time Frame: yearly ]

  • Controlled metastatic CNS disease ≥ 3 months
  • The ability to understand and willingness to sign a written informed consent form, and to comply with the protocol.

Exclusion Criteria:
