A randomized two-arm, open-label, multi-center phase II trial is designed with the goal being to evaluate the efficacy of combining vaccination of the P10s-PADRE formulation with neoadjuvant chemotherapy. Patients will be randomly assigned in a 2:1 ratio to standard chemotherapy plus P10s-PADRE or to standard chemotherapy alone. Efficacy will be based on the rate of pathologic Complete Response (pCR) observed among TN breast-cancer patients treated with the combination as compared with the group of patients who receive standard chemotherapy alone.
