Measure
Cyclophosphamide and Vaccine Only
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. allogeneic GM-CSF-secreting breast cancer vaccine: Given intradermally cyclophosphamide: Given IV
Cyclophosphamide, Vaccine and Trastuzumab
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. allogeneic GM-CSF-secreting breast cancer vaccine: Given intradermally trastuzumab: Given IV cyclophosphamide: Given IV

PRIMARY outcome

Timeframe: 6 months post-intervention

Population: Data was not evaluable in 2/30 participants from the cyclophosphamide and vaccine-only arm.

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.
