Brief Summary:
This randomized phase III trial studies how well paclitaxel, trastuzumab, and pertuzumab with or without atezolizumab works in treating patients with breast cancer that has spread to other parts of the body (metastatic). Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Trastuzumab is a form of "targeted therapy" because it works by attaching itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Monoclonal antibodies, such as pertuzumab, may interfere with the ability of cancer cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving paclitaxel, trastuzumab, and pertuzumab with or without atezolizumab may kill more tumor cells.

Primary Outcome Measures :
- Progression free survival [ Time Frame: The time from randomization to the first documented progressive disease assessed up to 7 years ]Will be determined using the current Response Evaluation Criteria in Solid Tumors 1.1 criteria. Analysis will be based on the intent to treat population. The stratified log-rank test will be used to compare the progression free survival between the two treatment arms with the following stratification factors: prior neoadjuvant or adjuvant therapy with trastuzumab (no; yes), estrogen receptor status (positive; negative), disease sites (any visceral without brain metastasis; non-visceral only without brain metastasis; brain metastasis), and choice of taxane (paclitaxel; docetaxel). The Kaplan-Meier estimates will be calculated by treatment arms. Stratified Cox proportional hazards models to estimate the hazard ratio.
Secondary Outcome Measures :
- Overall survival [ Time Frame: The time from randomization to death from any cause, assessed up to 7 years ]Analysis will be based on the intent to treat population. The Kaplan-Meier estimates will be calculated by treatment arms. Stratified Cox proportional hazards models to estimate the hazard ratio.
- Overall objective response [ Time Frame: Up to 7 years ]Defined as complete response or partial response. Will be determined using Response Evaluation Criteria in Solid Tumors 1.1 criteria.
- Duration of objective response [ Time Frame: From the date of initial confirmed partial response or complete response until the date of progressive disease or death from any cause assessed up to 7 years ]Tumor responses will be based on the current Response Evaluation Criteria in Solid Tumors 1.1 criteria.
- Cumulative incidence of brain metastases [ Time Frame: The time from randomization to documentation of brain metastases, assessed up to 7 years ]Analysis will be based on the intent to treat population. The Kaplan-Meier estimates will be calculated by treatment arms. Stratified Cox proportional hazards models to estimate the hazard ratio.
- Frequency of adverse events, including late immune-related toxicities [ Time Frame: Up to 7 years ]Will be categorized using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0.

- Patients not receiving anti-coagulant therapy must have prothrombin time (PT) and international normalized ratio (INR) =< 1.5 x ULN within 14 days prior to study entry; for laboratories that do not report an ULN for the INR assay, use =< 1.5 as the value for the ULN; patients receiving anti-coagulants should have a baseline INR assessed, but the value does not affect eligibility
- A serum thyroid-stimulating hormone (TSH) and AM (preferably in morning) cortisol must be obtained within 14 days prior to study entry to obtain a baseline value; patients with abnormal TSH or AM cortisol baseline levels should be further evaluated and managed per institutional standards; asymptomatic patients who require initiation or adjustment of medication or are followed without initiating treatment based on endocrinologist's recommendations are eligible
- Left ventricular ejection fraction (LVEF) assessment must be performed within 6 weeks prior to study entry; (LVEF assessment performed by echocardiogram is preferred; however, multigated acquisition scan (MUGA) scan may be substituted based on institutional preferences); the LVEF must be >= 50% regardless of the cardiac imaging facility's lower limit of normal
