Brief summary
Women with biopsy-proven ductal carcinoma in situ (DCIS) will be enrolled into two cohorts. One cohort will receive neoadjuvant therapy with an aromatase inhibitor or selective estrogen receptor modulator (SERM) for about 12 weeks prior to surgery at 12 weeks. The second cohort will receive neoadjuvant therapy with an aromatase inhibitor or selective estrogen receptor modulator and MUC1 vaccination (MUC1 peptide + Hiltonol®) pre-operatively at baseline, and weeks 2 and 10, followed by surgery at about 12 weeks. Patients in the vaccine cohort will be offered an optional boost vaccine 6 months after surgery.
Detailed description
Ductal carcinoma in situ (DCIS) is frequently detected by screening mammography, and may develop into invasive disease. However, not all DCIS will progress to invasive breast cancer, and some patients are overtreated. Vaccines for DCIS might facilitate therapeutic de-escalation, and allow less aggressive therapy. The TAA MUC1 is expressed in DCIS, and vaccines specific for MUC1 are safe and decrease the rate of recurrence of high-risk premalignant lesions in colon cancer. This clinical trial is designed to evaluate mechanisms of immune activation and suppression in pre and post-menopausal female patients with DCIS, both within the peripheral blood and within the DCIS lesion, and will provide data to guide the development of larger trials to evaluate the impact of a MUC1 vaccine to prevent disease recurrence. Ultimately, vaccine success in intercepting the development of breast cancer will provide critical data for the application of these strategies in breast cancer prevention in high-risk individuals.
Interventions
BIOLOGICALMUC1 Peptide Vaccine
MUC1, a therapeutic vaccine, is a transmembrane glycoprotein and a member of the mucin family of molecules.
DRUGHiltonol®
A synthetic dsRNA viral mimic and host-defense activator, mimics nature by combining the essential elements of human immunity.
DRUGAromatase Inhibitor
A type of hormone therapy for cancer used to inhibit aromatase to treat a hormone-related breast cancer.
DRUGSelective estrogen receptor modulator (SERM)
A type of hormone therapy that blocks cancer cells from being able to use estrogen to grow. prescribed for hormone receptor-positive breast cancer.

Inclusion criteria
1. Females, 18 years of age or older. Pre-menopausal women must use an effective method of contraception during the study. 2. Capable of providing informed consent and willing to comply with study procedures 3. Biopsy-proven ER+ DCIS * The signed pathology report from the attending pathologist will be used to determine eligibility * Sufficient amount of DCIS remaining in the diagnostic core biopsy block(s) and available for research * Patients with DCIS suspicious for microinvasion on core biopsy will be eligible because many of these patients will not have invasion on final pathology * Women presenting with concurrent bilateral DCIS are eligible only if both the right and left DCIS lesions are ER+, and tissue from both sides will be analyzed and must meet the criteria below 4. DCIS must be ≥ 1cm based on the extent of calcifications on mammogram, the presence of a mass on ultrasound or enhancement on MRI OR DCIS ≥ 5mm on one single core by pathologic evaluation OR DCIS \< 5mm if identified in ≥ 2 cores 5. Candidate for selective estrogen receptor modulator or aromatase inhibitor 6. Surgery planned as part of definitive local therapy 7. ECOG PS 0-1 8. Absolute neutrophil count ≥ 1.5 x 109/L 9. Platelet count ≥ 100 x 109/L 10. Hemoglobin ≥ 9 g/dl or ≥ 5.6 mmol/L 11. Creatinine ≤ 1.5X the upper limit of normal OR creatinine clearance ≥ 60 ml/min 12. Total bilirubin ≤ 1.5X the ULN; ≤ 2x ULN for patients with Gilbert's disease 13. AST and ALT ≤ 2.5X ULN 14. INR/PT/aPTT ≤ 1.5X ULN or within the therapeutic range if on anti-coagulation 15. If pre-menopausal, negative urine or serum pregnancy test
Exclusion criteria
1. Invasive breast cancer \> 1mm on pathologic evaluation 2. Second malignancy within the last 5 years (definitively treated superficial non-melanoma skin cancer, melanoma in situ, cervical carcinoma in situ allowed) 3. Current hormone replacement therapy, selective estrogen receptor modulator therapy, or aromatase inhibitor therapy--if yes, wash out of 30 days must occur prior to baseline biopsy for the study 4. Recurrent ipsilateral DCIS 5. Current steroid therapy (doses for physiologic replacement in adrenal dysfunction or for contrast allergy pre-medication for contrast allergy or similar indication allowed, topical, ocular and intranasal steroids allowed) 6. Current Immunomodulator therapy (includes anti-CD20 antibodies) 7. History of autoimmune disease requiring systemic immunosuppression, or active autoimmune disease. Replacement therapy with thyroxine, insulin, and physiologic corticosteroids for adrenal or pituitary insufficiency is acceptable. 8. History of immune deficiency 9. Active infection requiring systemic therapy 10. Any medical or psychiatric condition, substance abuse disorder, medical therapy, or laboratory abnormality that might interfere with the patient's participation for the full duration of the study or compliance with the requirements of the study 11. Known active hepatitis B (hepatitis B surface antigen-reactive) or hepatitis C (hepatitis C virus RNA positive). Patients who are hepatitis B core antibody positive without hepatitis B surface antigen reactivity are eligible. Patients who have antibody for hepatitis C are eligible only if hepatitis C RNA is negative by PCR. 12. Known history of HIV (presence of HIV antibodies for HIV 1 and HIV 2) 13. Received a live vaccine within 30 days of the first dose of treatment 14. History of allergies to any component of the MUC1 vaccine or HiltonolR adjuvant 15. Participation on any investigational vaccine, drug, or device trial within the last 30 days 16. Pregnant or breastfeeding
