Olaparib With or Without Atezolizumab in Treating Patients With Locally Advanced Unresectable or Metastatic Non-HER2-Positive Breast Cancer
This randomized phase II trial studies how well olaparib with or without atezolizumab work in treating patients with non-HER2-positive breast cancer that has spread from its original site of growth to nearby tissues or lymph nodes and is not amenable to surgical resection (locally advanced unresectable) or has spread to other places in the body (metastatic). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. It is not known whether giving olaparib with or without atezolizumab will work better in patients with non-HER2-positive breast cancer.
