This is a randomized open-label phase 2 study to evaluate the efficacy and safety (as assessed by pCR) of the NANT Neoadjuvant TNBC Vaccine regimen (experimental arm) compared to the SoC dose-dense regimen of doxorubicin/cyclophosphamide followed by paclitaxel (control arm).

Detailed Description

      Treatment will be administered in 2 phases, a neoadjuvant phase and a postoperative phase.
      The neoadjuvant phase will be 18 weeks for patients enrolled in the experimental arm and 16
      weeks for those enrolled in the control arm.

      Following the neoadjuvant phase, all subjects will undergo determination of their current
      response status and appropriate breast surgery and node dissection after which assessment for
      pCR will be conducted following completion of neoadjuvant systemic therapy. Pathologists
      interpreting surgical specimens for pCR assessment will be blinded to the treatment arm.

      All subjects, regardless of whether or not they have achieved a pCR, will then enter the
      postoperative phase where they will receive adjuvant treatment. A small portion of the
      corresponding neoadjuvant therapy, either nab-paclitaxel or paclitaxel, will be administered
      as adjuvant treatment postoperatively. Adjuvant treatment will continue in the postoperative
      phase until the subject experiences unacceptable toxicity (not correctable with dose
      reduction), withdraws consent, or if the Investigator feels it is no longer in the subject's
      best interest to continue treatment.

             IRB or Independent Ethics Committee (IEC) guidelines.

          3. Histologically confirmed stage II or III TNBC. Subjects must be treatment naïve. TNBC
             is defined as breast cancer that lacks estrogen receptor (ER) and progesterone

          5. Have at least 1 measurable lesion of ≥ 1.0 cm.

          6. Must have a recent FFPE tumor biopsy specimen and be willing to release the specimen
             for prospective and exploratory tumor molecular profiling. If an historic specimen is
             not available, the subject must be willing to undergo a biopsy during the screening
             period, if considered safe by the Investigator.

          7. Must be willing to provide blood samples prior to the start of treatment on this study
             for prospective tumor molecular profiling and exploratory analyses.

             by this protocol.

          9. Agreement to practice effective contraception for female subjects of child-bearing
             potential and non-sterile males. Female subjects of child-bearing potential must agree
             to use effective contraception for up to 1 year after completion of therapy, and
             non-sterile male subjects must agree to use a condom for up to 4 months after
             treatment. Effective contraception includes surgical sterilization (eg, vasectomy,
             tubal ligation), two forms of barrier methods (eg, condom, diaphragm) used with
             spermicide, intrauterine devices (IUDs), and abstinence.

             treatment-related complications.

          2. Systemic autoimmune disease (eg, lupus erythematosus, rheumatoid arthritis, Addison's
             disease, and autoimmune disease associated with lymphoma).
