|Condition or disease||Intervention/treatment||Phase|
|Triple Negative Breast Cancer Anthracycline-refractory TNBC||Drug: Docetaxel Drug: Pembrolizumab Drug: IL-12 gene therapy||Phase 2|
The purpose of this study is to learn how triple negative breast cancer (TNBC) responds to the use of chemotherapy, pembrolizumab, and gene therapy together in patients who have previously not responded to treatment. We will also look at the effects, good or bad, the study therapy has on you and your TNBC.
Chemotherapy given before breast cancer surgery is called neoadjuvant chemotherapy. It shrinks the breast tumor, so it is easier to remove during surgery. Docetaxel is often used for the neoadjuvant treatment of breast cancer. Unfortunately, a lot of breast tumors do not shrink with docetaxel chemotherapy treatment. Docetaxel chemotherapy is standard care for TNBC.
Pembrolizumab is a type of treatment that stimulates your own immune system to attack cancer cells. Your immune system is normally your body's first defense against threats like cancer. However, sometimes cancer cells produce signals that prevent the immune system from detecting and killing them. Pembrolizumab helps your immune system so it can detect and attack cancer cells. Chemotherapy plus pembrolizumab has been shown to be better than chemotherapy alone for shrinking breast tumors before surgery.
To help increase the tumor-shrinking activity of docetaxel chemotherapy and pembrolizumab, you will be given more treatments, Interleukin-12 (IL-12) gene therapy This treatments will be used to boost the cancer-fighting ability of your immune system. Thus, the use of IL-12 gene therapy with docetaxel chemotherapy and pembrolizumab may make your immune system work harder to shrink your tumor. IL-12 is a substance that is normally made by certain immune cells in the body. IL-12 stimulates T cells, a special type of immune cell in the blood, to respond to threats to your body like cancer.
After you finish the study treatment, you will have your breast cancer surgery.

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||Female|
|Accepts Healthy Volunteers:||No|
Patients are eligible to be included in the trial only if all of the following criteria apply:
- The patient (or legally acceptable representative if applicable) provides written informed consent for the trial.
- Female ≥ 18 years of age on the day of informed consent signing.
- Histologically confirmed triple negative breast cancer is defined as estrogen receptor (ER), progesterone receptor (PR), and HER2 negative. ER/PR negativity is defined as <10% IHC staining of any intensity.
HER2 negativity is defined as the following per the 2018 American Society of Clinical Oncology and College of American Pathologists guidelines.
4. Refractory to standard neoadjuvant anthracycline-containing chemotherapy regimen, demonstrated on MRI.
5. Bilateral breast cancers that individually meet eligibility criteria are allowed.
6. Prior immunotherapy treatment allowed. 7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 8. Adequate organ function as defined in Table 1. All screening labs should be performed within 28 days of trial treatment initiation.
9. Cardiac ejection fraction ≥45%. 10. A female patient is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
- Not a woman of childbearing potential (WOCBP) OR
A WOCBP who agrees to follow the contraceptive guidance in during the treatment period and for at least 120 days after the last dose of trial treatment. WOCBP must have a negative serum pregnancy test (β-human chorionic gonadotropin [β-HCG]) within 72 hours prior to trial treatment administration.
11. Willing to provide biopsy tissue as required by the trial. 12. Willing and able to comply with the protocol for the duration of the trial including undergoing treatment and scheduled visits and examinations.
- History of poorly controlled hypertension (defined as systolic blood pressure >150 mmHg). Patients whose hypertension has been well controlled on the same treatment for 1 year prior to Cycle 1, Day 1 are eligible. Only patients on single-agent antihypertensive therapy are allowed.
- History of New York Heart Association class III or greater cardiac disease.
- History of myocardial infarction, stroke, ventricular arrhythmia, or greater than first-degree conduction defect within the past 12 months.

- Absolute corrected QT interval of >480 msec in the presence of potassium >4.0 mEq/L and magnesium >1.8 mg/dL.
- Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to trial treatment administration.
NOTE: Patients who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.
