High Dose Radiation Therapy With Pembrolizumab and Chemotherapy for the Treatment of Patients With PD-L1 Positive Metastatic Triple Negative Breast Cancer

This phase II trial tests how well radiation therapy with pembrolizumab and chemotherapy (paclitaxel or nab-paclitaxel or carboplatin and gemcitabine) works in treating patients with PD-L1 positive triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel which may have fewer side effects and work better than other forms of paclitaxel. Carboplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill cancer cells. High dose radiation therapy with pembrolizumab and chemotherapy may effective in treating patients with PD-L1 positive metastatic triple negative breast cancer.
