Brief Summary:
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 bodys 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
Detailed Description:
PRIMARY OBJECTIVE
I To evaluate the 12 month progression-free survival PFS in PD-L1 positive triple negative breast cancer patients treated with high dose radiotherapy before and concurrently with the first cycle of pembrolizumab plus chemotherapy
SECONDARY OBJECTIVES
I To evaluate the objective response rate ORR in non-irradiated lesions nine weeks after the first dose of pembrolizumab in PD-L1 positive triple negative breast cancer patients treated with high dose radiotherapy before and concurrently with the first cycle pembrolizumab plus chemotherapy ORR per Response Evaluation Criteria in Solid Tumors RECIST 11
II To determine if targeted high dose radiotherapy to up to 3 metastatic sites in combination with pembrolizumab plus chemotherapy in patients with metastatic triple negative breast cancer 2 sites adversely increases the frequency and severity of toxicities associated with radiotherapy or pembrolizumab plus chemotherapy when administered separately
III To determine progression-free survival PFS in breast cancer patients treated with high dose radiotherapy pembrolizumab and chemotherapy
EXPLORATORY OBJECTIVES
I To collect store and analyze circulating tumor deoxyribonucleic acid ctDNA in metastatic breast cancer patients treated with radiotherapy pembrolizumab and chemotherapy to determine the relationship between ctDNA and PFS and ORR
II To collect store and analyze tumor tissue from a non-irradiated metastatic breast cancer site before and after radiotherapy to explore the immune tumor microenvironment and the immunoscore and the relationship between the immunoscore and ORR and PFS in metastatic breast cancer patients treated with pembrolizumab and chemotherapy
OUTLINE
Patients undergo radiation therapy once every other day for 3 doses Beginning within 48 hours of their first dose of radiation therapy patients receive standard of care pembrolizumab intravenously IV on day 1 of each cycle Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity Patients also receive 1 of 3 standard of care chemotherapy options nab-paclitaxel IV on days 1 8 and 15 of each cycle or paclitaxel IV on days 1 8 and 15 of each cycle or carboplatin IV and gemcitabine IV on days 1 and 8 of each cycle Cycles of nab-paclitaxel and paclitaxel repeat every 28 days and cycles of carboplatin and gemcitabine repeat every 21 days in the absence of disease progression or unacceptable toxicity Additionally patients undergo a biopsy at baseline and 2 weeks after radiation therapy and also undergo computed tomography CT scans bone scans and blood sample collections throughout the trial
After completion of study treatment patients are followed up every 12 weeks
