研究概览
简要总结
RATIONALE: Biological therapies, such as agatolimod, may stimulate the immune system in different ways and stop tumor cells from growing. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving agatolimod together with trastuzumab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving agatolimod together with trastuzumab works in treating patients with locally advanced or metastatic breast cancer.
详细描述
OBJECTIVES:
Primary
- To evaluate the progression-free survival of patients with HER2-overexpressing locally advanced or metastatic breast cancer treated with trastuzumab (Herceptin®) and agatolimod sodium.
Secondary
- To determine if agatolimod sodium augments antibody-mediated cytoxicity (ADCC) against trastuzumab-coated target cells by evaluating the ability of patient immune-effector cells to conduct ADCC and produce interferon gamma.
