|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I/II Study of Combination Immunotherapy for the Generation of HER-2/Neu (HER2) Specific Cytotoxic T Cells (CTL) in Vivo|
- Immune response measured by cytokine flow cytometry (CFC) and HLA-A2 major histocompatibility complex tetramer analysis [ Time Frame: Up to 1.5 years (12 months following the last vaccination) ]Defined as either the development of, in patients with no measurable precursors at baseline, precursor frequencies > 1:20,000 as measured by CFC; or as a 2-fold increase in baseline precursor frequency in those patients who have a pre existent immune response.
- Incidence of adverse events graded using National Cancer Institute (NCI) Cancer Therapy Evaluation Program (CTEP) Common Terminology Criteria for Adverse Events (CTCAE), version 3.0 [ Time Frame: Up to 7 months (30 days following the last vaccination) ]Descriptive statistics will be used to summarize changes from baseline.
- Overall survival [ Time Frame: Up to 5 years ]Survival for the Stage IV breast cancer patients will be compared to historical control.

|Estimated Primary Completion Date:||May 2018 (Final data collection date for primary outcome measure)|
Experimental: Treatment (HER-2/neu peptide vaccine)
Patients receive HER-2/neu peptide vaccine ID once per month for 6 months in the absence of disease progression or unacceptable toxicity.
Biological: HER-2/neu Peptide Vaccine
Other Names:Other: Laboratory Biomarker Analysis
I. To evaluate the safety of administering a HER2 cytotoxic T-cell (CTL) peptide-based vaccine (HER-2/neu peptide vaccine) to stage IV breast and ovarian cancer patients receiving maintenance trastuzumab.
II. To quantify and characterize antigen specific T cell subsets specific to HER2 in peripheral blood mononuclear cell (PBMC) of patients after vaccination with a HER2 CTL peptide-based vaccine while receiving maintenance trastuzumab.
I. To evaluate overall survival (OS) in patients who complete a vaccination series with a HER2 CTL peptide-based vaccine while receiving maintenance trastuzumab.
Patients receive HER-2/neu peptide vaccine intradermally (ID) once per month for 6 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 1, 3, 6, and 12 months, and then yearly for up to 5 years.
