Purpose

RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an effective immune response to kill tumor cells. Biological therapies, such as cyclophosphamide and trastuzumab, may increase the number of immune cells and make the immune response stronger. It is not yet known whether giving cyclophosphamide together with vaccine therapy is more effective with or without trastuzumab in treating patients with metastatic breast cancer.

PURPOSE: This randomized phase II trial is studying the side effects of giving cyclophosphamide together with vaccine therapy and to see how well it works compared with giving cyclophosphamide and vaccine therapy together with trastuzumab in treating patients with metastatic breast cancer.

Arms	Assigned Interventions
Active Comparator: Arm I Patients receive cyclophosphamide IV over 30 minutes on day -1 and allogeneic GM-CSF-secreting breast cancer vaccine intradermally on day 0. Courses repeat every 4-6 weeks for 3 courses in the absence of disease progression or unacceptable toxicity. Patients then receive a fourth vaccination at 6-8 months.	Biological: allogeneic GM-CSF-secreting breast cancer vaccine Given intradermally Drug: cyclophosphamide Given IV
Experimental: Arm II Patients receive cyclophosphamide and the vaccine as in arm I and trastuzumab IV over 30-90 minutes on day -1. Courses repeat every 4-6 weeks for 3 courses in the absence of disease progression or unacceptable toxicity. Patients then receive a fourth vaccination at 6-8 months.

Detailed Description:

OBJECTIVES:

Primary

To evaluate the safety of cyclophosphamide-modulated vaccination with vs without trastuzumab in patients with breast cancer that does not overexpress HER-2/neu.
To compare the clinical benefit of cyclophosphamide-modulated vaccination with vs without trastuzumab in these patients.
To measure HER-2/neu-specific CD4+ and CD8+ T-cell immunity by delayed-type hypersensitivity (DTH) and ELISPOT.
To measure the pharmacodynamics of CD4+CD25+ regulatory T cells by flow cytometry.

Secondary

To assess the impact of trastuzumab on immune priming in vivo by immunohistochemistry of vaccine-site biopsies at day +3 and day +7 of courses 1 and 3 on the two study arms, comparing cellular infiltrates to those seen in previous preclinical and clinical models.
To measure hTERT-specific CD8+ T-cell immunity by ELISPOT.
To characterize the peripheral-memory T-cell pool.

Tertiary

To determine baseline and change in vaccine site-draining lymph node immunohistology and gene expression profile.
To develop the tandem tetramer/CD107a cytotoxicity assay for HER-2/neu-specific CD8+ T cells.
To measure novel T-cell responses induced by trastuzumab and cyclophosphamide-modulated vaccination.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive cyclophosphamide IV over 30 minutes on day -1 and allogeneic GM-CSF-secreting breast cancer vaccine intradermally on day 0. Courses repeat every 4-6 weeks for 3 courses in the absence of disease progression or unacceptable toxicity. Patients then receive a fourth vaccination at 6-8 months.
Arm II: Patients receive cyclophosphamide and the vaccine as in arm I and trastuzumab IV over 30-90 minutes on day -1. Courses repeat every 4-6 weeks for 3 courses in the absence of disease progression or unacceptable toxicity. Patients then receive a fourth vaccination at 6-8 months.

Skin punch and lymph node biopsies are collected at baseline and on days +3 and +7 of courses 1 and 3 for biomarker analysis.

After completion of study treatment, patients are followed periodically.
