Description:
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.

Purpose
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.
Detailed Description
The study is a single arm, open label, pilot study of safety and immune efficacy of peptide
vaccination with poly-ICLC in patients with stage IB-IIIA resected breast cancer.
Participants will be patients who have completed their last dose/treatment of any single
treatment or combination of adjuvant surgery, radiation, chemotherapy or trastuzumab therapy
between 45 days and 6 months (180 days) prior to enrollment.
Each vaccination will be administered on days 1, 8, 15, 36, 57, and 78. All participants will
receive 9 class I MHC-restricted synthetic peptides (restricted by HLA-A1, -A2, -A3, or -A31)
and a class II MHC-restricted tetanus helper peptide mixed with 1mg poly-ICLC and
administered in sterile water. The vaccine will be administered intramuscular (IM) (1 ml) and
intradermally (ID) (1 ml) at vaccination sites in the arm and leg. (Each vaccine given IM and
ID at one site; site to alternate between arm site opposite the breast cancer and an anterior
thigh site.) Participants will be screened for HLA type and must be HLA-A1, -A2, -A3, or -A31
(80% of the Virginia population in prior studies1).
Annual follow-up for progression and survival for 3 years after study withdrawal/completion.

Eligibility Criteria
Inclusion:
- Patients who have been diagnosed with clinical or pathologic stage I to stage IV
adenocarcinoma of the breast (any subtype) who have undergone, and recovered from
primary therapy (any combination of surgery, radiation, and/or chemotherapy and/or
HER2-directed therapy), with their last dose/treatment (of any single or combination
treatment) being between 28 days and 36 months prior to enrollment. Staging will be
based on the Seventh Edition AJCC staging system. (Systemic staging with CT or PET
scans is not required by AJCC and is not required or exclusionary for this trial).
- Stage IA patients must be high risk based upon triple negative status or HER2+ status
- Patients may or may not be receiving hormonal therapy at the time of study entry.
- Age ≥ 18 years at the time of enrollment
- ECOG performance status of 0 or 1
- Ability and willingness to give informed consent
- HLA-A1, -A2, -A3, or -A31 positive
- Adequate organ function
- HIV and Hepatitis C negative
- Subjects must have a minimum of two intact lymph node basins (any combination of
axillary and inguinal basins that have not undergone complete nodal dissection)
Exclusion Criteria
- Known or suspected allergies to any component of the vaccine
- Active infection requiring antibiotics are excluded.
- The following medications or treatments within the 4 weeks (28 days) prior to
consenting. These medication and treatments may not be re-started at any time
throughout the study in order to remain eligible.
- Breast tumor resection surgery (reconstructive surgery permitted)
- Chemotherapy
- Radiation therapy
- Allergy desensitization injections
- Growth factors (e.g., Procrit®, Aranesp®, Neulasta®)
