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.

Conditions

Interventions

BIOLOGICAL

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.

BIOLOGICAL

ER+/HER2-BC:DC vaccine+Preop chemo

ER+/HER2- BC patients will receive standard preop AC followed by weekly T given for 22 weeks. Chemo and DC vaccinations will be given intratumoral and subcutaneous, for 4 times prior surgery. During the AC cycles, vaccines will be given any day between Days 9-12 of Cycles 1 and 3 of AC. Vaccines will be given on Day 1 during Cycle 2 or Cycle 3 and on Day 1 during either Cycle 8 or Cycle 9 of T. Vaccine will be given after T infusion is completed. 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. 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 surgery and prior to radiation; the 2nd will occur 30 days ± 3 days after radiation; and the 3rd will occur 90 days ± 3 days after the 2nd boost.
