Brief Summary:
The purpose of this study is to look at the safety and immune response to a vaccine used in patients previously treated for HER2 (human epidermal growth factor receptor 2) positive breast cancer.

Condition or disease Intervention/treatment Phase
HER2-positive Breast Cancer Male Breast Cancer Stage II Breast Cancer Stage IIIA Breast Cancer Stage IIIB Breast Cancer Stage IIIC Breast Cancer Biological: HER-2/neu peptide vaccine Other: laboratory biomarker analysis Phase 1

Detailed Description:


I. To determine the safety profile of a peptide-based vaccine targeting HER-2/neu, in patients with stage II/III HER-2 positive breast cancer.

II. To determine the ability of this vaccination protocol to elicit an immune response as measured by activated HER-2/neu-specific T lymphocytes or high-affinity antibodies.


I. To compile descriptive follow-up data regarding vital status and disease recurrence.

II. To determine if HER-2/neu peptide 885 generates a T cell response that is specific to HER-2/neu or is cross-reactive with epidermal growth factor receptor (EGFR) protein.

III. To determine if the human leukocyte antigen (HLA)-DR epitopes contain HLA class I embedded epitopes.


Patients receive HER-2/neu peptide vaccine intradermally (ID) every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for up to 2 additional years.

Arm Intervention/treatment
Experimental: Treatment (HER-2/neu peptide vaccine)
Patients receive HER-2/neu peptide vaccine ID every 28 days for up to 6 courses in the absence of disease recurrence or unacceptable toxicity.
Biological: HER-2/neu peptide vaccine
Given ID
Other Name: HER-2

Other: laboratory biomarker analysis
Correlative studies

Primary Outcome Measures :
  1. Proportion of patients who experience toxicities of attribution during the course of treatment (grades 3-5 of the NCI's Cancer Therapy Evaluation Program [CTEP] Common Terminology Criteria for Adverse Events, version 4.0) for 2 years. [ Time Frame: Assessed up to 2 years following final immunization ]
    The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.

  2. To determine the ability of this vaccination protocol to elicit an immune response as measured by activated HER-2/neu-specific T lymphocytes or high-affinity antibodies [ Time Frame: 30 months ]
    Immune responses to to the vaccine components will be periodically assessed using various assays measuring cytokine release, frequency of T cells, and antibody generation.

Secondary Outcome Measures :
  1. Disease-free survival [ Time Frame: 30 months ]
    Disease-free survival is defined as the time from registration to documentation of disease recurrence, second primary, or death without disease recurrence or second primary. The distribution of disease-free and overall survival times will be estimated using the method of Kaplan-Meier.

Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:

  • Pregnant women
  • Nursing women unwilling to stop breast feeding
  • Men or women of child bearing potential who are unwilling to employ adequate contraception from the time of registration through 6 months after the final vaccine cycle Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens Immunocompromised patients including patients known to be human immunodeficiency virus (HIV) positive or those on chronic steroids; Note: must be off systemic steroids at least 90 days prior to registration; topical steroids or steroid eye drops are permitted Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
