Allogeneic granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting breast cancer vaccine: the vaccine containing a mixture of two GM-CSF-secreting allogeneic breast cancer cell lines (two parts 2T47D-V and one part 3SKBR3-7 mixed in a fixed dose of 5 X 10\^8 cells for each patient and each vaccination cycle) given intradermally every 4-6 weeks for 3 cycles and then a 4th dose given 6-8 months after beginning the study. Cyclophosphamide (Cy): 300 mg/m\^2 given intravenously every 4-6 weeks for 3 cycles and then once 6-8 months after beginning the study Trastuzumab : An initial loading dose of 4 mg/kg for participants beginning treatment with Trastuzumab, otherwise 2 mg/kg given every week intravenously

PRIMARY outcome

Timeframe: At 6 and 12 months from start of treatment

Clinical benefit is defined as the proportion of patients achieving complete response, partial response, or stable disease by RECIST. Complete response (CR) is defined as total disappearance of all clinical evidence of reversible disease. A partial response (PR) is defined as a \>=30% reduction in tumor target lesions. Stable disease (SD) is defined as disease status that fails to qualify as as a response (CR or PR) or progressive disease (increase of at least 20% in tumor target lesions).

SECONDARY outcome

Timeframe: 30 days after each vaccine, up to 9 months

The number of participants with a Delayed Type Hypersensitivity (DTH) response was measured as an indicator of immune response. Participants were considered to have a DTH response if they had increased induration (\>5mm from baseline) at the site of injection 2-3 days after intradermal injection with human epidermal growth factor receptor 2 (HER-2) peptides. This peptide injection was given 28 days after each dose of vaccine.
