简要总结
This pilot phase I trial studies whether it is feasible to conduct a detailed molecular profile of triple negative breast cancer as part of a treatment strategy that asks whether or not we can lower the chance of breast cancer growing or spreading, by treating with a combination of PARP inhibitor how well (olaparib) and immune therapy (durvalumab). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving olaparib and durvalumab may work better in treating participants with metastatic triple negative breast cancer.
