Cyclophosphamide and Vaccine Therapy With or Without Trastuzumab in Treating Patients With Metastatic Breast Cancer

Brief Summary
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.

Outcome Measures
Primary Outcomes (4)
Toxicity as Assessed by Number of Grade 3 or 4 Adverse Events
Number of grade 3 or 4 nonhematologic toxicity (except alopecia), or any grade 4 hematologic toxicity as defined by NCI CTCAE v3.0
3 years
Clinical Benefit (CB) as Assessed by Progression Free Survival at Six Months
Progression-free survival is measured as percentage of participants with stable disease or complete response, as defined by RECIST criteria, six months after receiving last vaccination. Progressive disease (PD) will be defined by the appearance of a new lesion, or by an increase of at least 20% in the sum of the longest diameter of target lesions, taking as a reference that smallest sum longest diameter recorded since the study intervention began. In the case of bone lesions, progressive disease will be established after eight weeks of increasing or new lesions if there is subjective progressive disease as noted by increasing bone pain or decreasing performance status. These observations must be present for at least two measurement periods separated by at least four weeks.

Study Arms (2)
Cyclophosphamide and Vaccine only
ACTIVE COMPARATORPatients 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.
Cyclophosphamide, Vaccine and Trastuzumab
EXPERIMENTALPatients 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.
