NCT03554109

Brief Summary

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).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years.
  • Able to understand and provide a signed informed consent that fulfills the relevant IRB or Independent Ethics Committee (IEC) guidelines.
  • 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 receptor (PgR) expression, and human epidermal growth factor receptor 2 (HER2) overexpression and/or amplification.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2
  • Have at least 1 measurable lesion of ≥ 1.0 cm.
  • 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.
  • Must be willing to provide blood samples prior to the start of treatment on this study for prospective tumor molecular profiling and exploratory analyses.
  • Ability to attend required study visits and return for adequate follow-up, as required by this protocol.
  • 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.

You may not qualify if:

  • Serious uncontrolled concomitant disease that would contraindicate the use of the investigational drug used in this study or that would put the subject at high risk for treatment-related complications.
  • Systemic autoimmune disease (eg, lupus erythematosus, rheumatoid arthritis, Addison's disease, and autoimmune disease associated with lymphoma).
  • History of organ transplant requiring immunosuppression.
  • History of or active inflammatory bowel disease (eg, Crohn's disease and ulcerative colitis).
  • Inadequate organ function, evidenced by the following laboratory results:
  • Absolute neutrophil count (ANC) \< 1,000 cells/mm\^3.
  • Platelet count \< 75,000 cells/mm\^3.
  • Uncorrectable grade 3 anemia (hemoglobin \< 8 g/dL).
  • Total bilirubin greater than the upper limit of normal (ULN; unless the subject has documented Gilbert's syndrome).
  • Aspartate aminotransferase (AST \[SGOT\]) or alanine aminotransferase (ALT \[SGPT\]) \> 2.5 × ULN (\> 5 × ULN in subjects with liver metastases).
  • Alkaline phosphatase (ALP) levels \> 2.5 × ULN (\> 5 × ULN in subjects with liver metastases, or \>10 × ULN in subjects with bone metastases).
  • Serum creatinine \> 2.0 mg/dL or 177 μmol/L.
  • Serum anion gap \> 16 mEq/L or arterial blood with pH \< 7.3.
  • Uncontrolled hypertension (systolic \> 160 mm Hg and/or diastolic \> 110 mm Hg) or clinically significant (ie, active) cardiovascular disease, cerebrovascular accident/stroke, or myocardial infarction within 6 months prior to first study medication; unstable angina; congestive heart failure of New York Heart Association grade 2 or higher; or serious cardiac arrhythmia requiring medication.
  • Serious myocardial dysfunction defined by echocardiogram (ECHO) as absolute LVEF 10% below the institution's lower limit of predicted normal.
  • +11 more criteria
