Trastuzumab, Vinorelbine Tartrate, and Avelumab with or without Utomilumab in Treating Patients with HER2-Positive Metastatic Breast Cancer
This phase II trial studies the how well trastuzumab, vinorelbine tartrate, and avelumab with or without utomilumab work in treating patients with HER2-positive breast cancer that has spread to other parts of the body (metastatic). Trastuzumab is a form of targeted therapy because it attaches 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. Immunotherapy with monoclonal antibodies, such as avelumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as vinorelbine tartrate, 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. Utomilumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving trastuzumab, vinorelbine tartrate, and avelumab with or without utomilumab may work better in treating patients with breast cancer.
