Brief Summary:
This is a single institution, open-label randomized phase 1 trial of neoantigen DNA vaccine alone vs. neoantigen DNA vaccine plus durvalumab in triple negative breast cancer (TNBC) patients following standard of care therapy. Patients with newly diagnosed clinical stage II-III TNBC are eligible for enrollment. Patients will receive standard of care therapy including chemotherapy, surgery and radiation therapy as clinically indicated. Following standard of care therapy, patients will be randomized to receive either a neoantigen DNA vaccine alone, or a neoantigen DNA vaccine + durvalumab.

Arm Intervention/treatment
Experimental: Neoantigen DNA vaccine + Durvalumab
  • The first neoantigen DNA vaccine injection will take place up to 90 days following the completion of standard of care therapy. The day of the first vaccine injection will be referred to as Day 1
  • The schedule of vaccination is Day 1, Day 29 ± 7, Day 57 ± 7, Day 85 ± 7, Day 113 ± 7, and Day 141 ± 7 with at least 21 days between injection days
  • For patients who are randomized to the neoantigen DNA vaccine plus durvalumab arm, the neoantigen-specific T cell response will be assessed prior to Day 85. If a neoantigen-specific T cell response is present, durvalumab will be started on Day 85, and will be administered Q4W at a dose of 1500 mg over the course of 60 minutes. If a neoantigen-specific T cell response is not present, these patients will be replaced but may continue to receive the neoantigen DNA vaccine on study. They will not be transferred to the vaccine-only arm.

Secondary Outcome Measures :
  1. Immune response to neoantigen DNA vaccines given alone or in combination with durvalumab as measured by luminex assay [ Time Frame: Up to 1 year ]

  2. Immune response to neoantigen DNA vaccines given alone or in combination with durvalumab as measured by ELISPOT [ Time Frame: Up to 1 year ]
    -Peripheral blood will be collected at multiple time points before and after vaccination

Criteria

Inclusion Criteria:

  • Histologically confirmed diagnosis of invasive breast cancer.

  • Body weight > 30 kg.
  • Evidence of post-menopausal status or negative urine or serum pregnancy test for female pre-menopausal subjects. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:

    • Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
    • Women ≥ 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, or hysterectomy).
