Brief Summary:
The purpose of this research study is to test the safety and effectiveness of adding interleukin 12 (IL-12) gene therapy and L-NMMA to pembrolizumab in patients with early-stage triple negative breast cancer (TNBC) receiving standard of care preoperative (neoadjuvant) chemotherapy.

Condition or disease Intervention/treatment Phase
Triple Negative Breast Cancer Drug: Docetaxel Drug: Doxorubicin Drug: Cyclophosphamide Drug: Pembrolizumab Drug: IL-12 gene therapy Drug: L-NMMA Phase 2

Detailed Description:

The purpose of this research study is to test the safety and effectiveness of adding interleukin 12 (IL-12) gene therapy and L-NMMA to pembrolizumab in patients with early-stage triple negative breast cancer (TNBC) receiving standard of care neoadjuvant chemotherapy. Chemotherapy given before breast cancer surgery is called neoadjuvant chemotherapy. It shrinks the breast tumor so it is easier to remove during surgery. Docetaxel, doxorubicin, and cyclophosphamide chemotherapy (called TAC chemotherapy) is often used for the neoadjuvant treatment of breast cancer. Unfortunately, a lot of breast tumors do not shrink with TAC chemotherapy treatment.

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 increase the cancer-fighting ability of your immune system, you will be given 1 or 2 more treatments. These include IL-12 gene therapy and L-NMMA.
