Brief Summary

The primary objective of this study is to determine the safety and feasibility of combining cyclin B1/WT-1/CEF (antigen)-loaded DC vaccination with preoperative chemotherapy.

The secondary objectives of this trial are to determine pathologic complete response rates; disease-free survival; to assess immune biomarkers of immunity (antigen-specific CD8+ T cell immunity and TH2 T cells) in breast cancer biopsy specimens and blood samples in patients receiving DC vaccinations; and to assess the feasibility of immunizing LA TNBC and ER+/HER2- BC patients with patient-specific tumor antigens.

Detailed Description

Recent studies have shown that human breast cancers can be immunogenic, and that enhancing the immune effector function already present may augment the cytotoxic effects of standard therapies.

vaccination remains the most attractive strategy because of its expected inducement of both therapeutic T cell immunity (effector T cells) and protective T cell immunity (tumor-specific memory T cells that can control tumor relapse). Several clinical studies have now demonstrated that immunity against tumor antigens can be enhanced in cancer patients by vaccination with ex vivo-generated tumor antigen-loaded dendritic cells (DCs). This strategy capitalizes on the unique capacity of DCs to prime lymphocytes and to regulate and maintain immune responses.

Our goals are to boost T cell immunity targeted against breast cancer utilizing a tumor antigen-loaded DC vaccine, to enhance chemotherapy effectiveness and decrease tumor metastagenicity, and to decrease the recurrence rates of LA TNBC and ER+/HER2- BC. Patients will be treated with a combination of antigen-loaded DC vaccinations along with standard preoperative chemotherapy, to improve immunogenicity and to increase the pCR rate achieved with standard therapy. The trial will consist of 2 patient cohorts: TNBC and ER+/HER2- BC.

Study Groups

LA TNBC: DC vaccine+Preop chemo

LA TNBC patients will receive standard preop AC followed by TCb chemo for 24 weeks. Chemo and DC vaccinations will be given intratumoral and subcutaneous for 4 times prior surgery. During the AC cycles, vaccines will be given on any day between Days 9-12 of Cycles 1 and 3 of AC. Vaccines will be given on any day between Days 11-15 of Cycles 1 and 3 of TCb. Patients will undergo biopsies of their cancer prior to treatment and 1-2 days prior to or on Day 1 of Cycle 4 of AC. After this, patients will have surgery, locoregional radiation therapy to the breast or chest wall and regional lymphatics per standard of care, and will receive 3 boost DC vaccinations subcutaneously, rotating injection sites in the upper arm. The 1st vaccination will occur after the surgery and prior to radiation; 2nd will occur 30 days ± 3 days after radiation; the 3rd will occur 90 days ± 3 days after the 2nd boost.
