8.Signed written informed consent prior to trial entry.
9.Willing and able to comply with the protocol for the duration of the trial.
10.No more than two prior chemotherapy regimens for locally advanced/metastatic disease (adjuvant chemotherapy after primary therapy is not counted as a regimen).
11.No more than three prior lines of endocrine treatment for locally advanced/metastatic disease.

Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective of the trial is to demonstrate evidence of clinical efficacy of HER-2 Protein AutoVac(TM), that is the number of evaluable patients with evidence of clinical benefit, defined as:<br>·A complete response (CR) or partial response (PR), or<br>·Stable disease (SD) for at least 6 months (26 weeks).<br>;Secondary Objective: The secondary objectives of the trial are:<br>·To obtain data on the immune response following long-term treatment.<br>·To obtain safety data on long-term use.<br>;Primary end point(s): The primary endpoint of the trial is clinical benefit rate, defined as:<br>·Clinical Response or Partial Response, or<br>·Stable Disease for at least 6 months (26 weeks).<br>
