Study Summary

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 to nearby tissue or lymph nodes (locally advanced), that cannot be removed by surgery (unresectable), or that has spread from where it first started (primary site) to other places in the body (metastatic). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. 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.

Primary Outcome

The study arms will be compared for duration of response survival with Kaplan-Meier estimates and log-rank tests. The Rothman confidence interval (CI), which is based on Greenwood's variance, Thomas and Grunkemeier CI, and the simultaneous confidence bands by Nair and Hall and Wellner, will be reported. In addition, the possible risk factors will be compared for survival with log-rank test. For multivariate analysis, the proportional hazards Cox model will be applied to investigate potential pro
