Brief Summary

RATIONALE:

Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer.

PURPOSE:

To evaluate the efficacy of poly-ICLC + MUCI peptide vaccine in boosting the immunologic response to MUCI in patients with triple-negative BC

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of MUC1 peptide-poly-ICLC adjuvant vaccine in boosting systemic immunity to MUC1 in women who have completed therapy for AJCC(American Joint Committee on Cancer)stage I-III 'triple-negative' \[i.e., ER(-) PR(-) HER2/neu(-)\] breast cancer.

SECONDARY OBJECTIVES:

I. To evaluate the safety and toxicity of the MUC1 peptide and poly-ICLC vaccine in this cohort of patients.

OUTLINE:

Patients receive MUC-1 peptide vaccine subcutaneously (SC) and poly-ICLC vaccine SC in weeks 0, 2, and 10 in the absence of disease progression or unacceptable toxicity. Some patients may receive a booster vaccine in week 52. Patients will be followed for study-related Serious Adverse Events (SAEs) for a period of 30 days after their last vaccination. If a patient experiences a SAE while participating in this study, they will be followed until the resolution of the SAE.

Exclusion Criteria
  • Known metastatic BC

  • Active or uncontrolled infection
  • Psychiatric, addictive, or any disorder that compromises the ability to give informed consent to participate in or to comply with the requirements of the study
  • Concurrent systemic corticosteroid treatment - must be off all steroids for at least 4 weeks prior to vaccine administration
  • Any condition or behavior that in the judgment of the Investigator, would compromise the patient's ability to participate in the study

Primary Outcome Measures
NameTimeMethod
Proportion of patients showing a positive anti-MUC1 antibody responseAt week 12 (2 weeks after the 3rd injection)

Defined as a \>= 2-fold enhancement from baseline anti-MUC1 antibody immunity, or for subjects with no antibody to MUC1 at baseline, any detectable antibody immunity against MUC1. To test the hypothesis of a sufficient immunologic response, we will apply a Simon's optimum 2-stage design. The proportion of patients with an immunologic response will be calculated with a 95% confidence interval using method developed for multistage clinical trials.

Secondary Outcome Measures
NameTimeMethod
Safety and toxicity as assessed by NCI CTCWeeks 0, 2, 4, 10, 12, 52, and 54 and then for 30 days after completion of study treatment
