Atezolizumab, Paclitaxel, Trastuzumab, and Pertuzumab in Treating Patients with HER2 Positive Breast Cancer That Is Locally Recurrent, Metastatic, or Cannot Be Removed by Surgery
This phase IIa trial studies the side effects of atezolizumab when given together with paclitaxel, trastuzumab, and pertuzumab and to see how well it works in treating patients with HER2 positive breast cancer that has come back at or near the same place as the original (primary) tumor, has spread to other places in the body, or cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as atezolizumab, trastuzumab, and pertuzumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, 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. Giving atezolizumab, paclitaxel, trastuzumab, and pertuzumab may work better in treating patients with HER2 positive breast cancer.
