Study: NCT02938442

Intervention type: BIOLOGICAL
Group type: EXPERIMENTAL
Intervention: P10s-PADRE with MONTANIDE™ ISA 51 VG
Description: Subjects randomized to the control arm will receive SoC neoadjuvant chemotherapy starting on week 1. Doxorubicin and cyclophosphamide (AC) will be administered concurrently every two weeks for four cycles with pegfilgrastim (or equivalent growth factor) on day 2 of each AC cycle, followed by paclitaxel weekly x 12 weeks.

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Doxorubicin
Description: Subjects randomized to the chemo+vaccine arm will be immunized with P10s-PADRE in MONTANIDE™ ISA 51 VG a total of three times. The vaccine will be administered on weeks 1, 2 and 3 prior to chemotherapy. Then, they will start their SoC neoadjuvant chemotherapy on week 4. Doxorubicin and cyclophosphamide (AC) will be administered concurrently every two weeks for four cycles with pegfilgrastim (or equivalent growth factor) on day 2 of each AC cycle, followed by paclitaxel weekly x 12 weeks.
