Pilot Study of a Breast Cancer Vaccine Plus Poly-ICLC for Breast Cancer

Despite advances in surgical, radiation and medical therapies of early stage breast cancer, some patients will experience disease recurrence. Because recurrence may not happen for years after definitive treatment, there is a period of time between resection and relapse when micrometastatic disease may be amenable to immune eradication or modulation. While the ultimate goal of any cancer treatment is clinical efficacy, the immediate urgency in breast immunotherapy is to define treatments that have immunologic efficacy. In this study, the investigators will determine whether a vaccine consisting of nine-class I breast specific peptides plus a class II tetanus toxoid helper peptide is immunogenic when administered with poly-ICLC to participants with stage IB to IIIA breast cancer in the adjuvant setting.
