Purpose
This randomized phase I/II trial studies the side effects and best dose of rintatolimod when given together with vaccine therapy and sargramostim (GM-CSF) to see how well it works in treating patients with stage II-IV human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Vaccines made from synthetic HER2/neu peptides may help the body build an effective immune response to kill tumor cells that express HER-2/neu. Our group has developed vaccines against the HER2 protein that create immune responses and in this study we are researching different ways that we may be able to make that immune response even better. Adjuvants are one way to help vaccines produce stronger immune responses. Our group has typically used the adjuvant GM-CSF and in this study we would like to look at another adjuvant called rintatolimod. Giving vaccine therapy together with rintatolimod and/or GM-CSF may be an effective treatment for breast cancer

- Evaluation of immune response among the different treatment arms in Stage I and II [ Time Frame: Up to 12 months post-vaccination ] [ Designated as safety issue: No ]Use standard interferon (IFN)-gamma enzyme-linked immunospot (ELISPOT) assay to evaluate CD4+ Th1 T cell responses to HER2 immunizing peptides.
- Evaluation of safety and systemic toxicity among the different treatment arms in Stage I and II [ Time Frame: Up to 4 months ] [ Designated as safety issue: Yes ]Toxicity grading will be evaluated per Cancer Therapy Evaluation Program (CTEP) Common Terminology Criteria for Adverse Events (CTCAE) 4.0 and monitoring of adverse events (AEs) will be done per Food and Drug Administration (FDA) and National Cancer Institute (NCI) guidelines.
- Disease-free survival [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]Though not statistically powered to this endpoint, large differences if observed between the vaccine treatment groups will be noted and described.

Detailed Description:
OBJECTIVES:
I. To choose the most promising (maximum biologic dose [MBD]) of five different doses (4, 20, 79, 495 and 2000 mcg) of Ampligen (rintatolimod) administered intradermally (ID) as an adjuvant with HER2 vaccination, with respect to toxicity and incidence and magnitude of immune response.
II. To determine, using MBD of Ampligen (defined in first primary aim), whether Ampligen when given with GM-CSF as a combined adjuvant strategy with HER2 vaccination increases both the incidence and magnitude of HER2 Th1 immunity as compared to the standard GM-CSF adjuvant strategy.
OUTLINE: This will be a phase I-II randomized two-stage HER2 vaccine study in breast cancer patients.
STUDY STAGE I: There are five groups of patients randomized to 1 of 5 arms with each arm receiving the synthetic HER-2/neu peptide vaccine admixed with rintatolimod (different doses) given ID.
STUDY STAGE II: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive the synthetic HER-2/neu peptide vaccine admixed with rintatolimod given ID.
ARM II: 24 patients will receive the HER-2/neu peptide vaccine admixed with GM-CSF and the other 24 patients will receive the HER-2/neu peptide vaccine admixed with GM-CSF in additional to rintatolimod (dose set by Phase I group that had the most active response) given ID.
In both study stages, treatment repeats every month for up to 3 months in the absence of disease progression or unacceptable toxicity.
After completion of last vaccine, patients are followed up at 1 and 12 months.
