简要总结
Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Interleukin-2 may stimulate a person's white blood cells to kill breast cancer cells. Phase II trial to study the effectiveness of trastuzumab plus interleukin-2 in treating patients who have metastatic breast cancer that has not responded to previous trastuzumab therapy.
详细描述
PRIMARY OBJECTIVES:
I. To estimate the response rate and toxicity to low-dose IL-2 with intermediate-"pulse" dose interleukin 2 (IL-2) and trastuzumab in patients with uni-dimensional measurable metastatic breast cancer and human epidermal growth factor receptor 2 (HER2) positive (3+ overexpression by immunohistochemistry [IHC] method or positive by fluorescent in situ hybridization [FISH]) who either have had evidence of progressive disease while receiving a trastuzumab-containing regimen, or have had progressive disease within 12 months of receiving a trastuzumab-containing regimen.
SECONDARY OBJECTIVES:
I. To perform correlative immunologic assays to determine the degree of natural killer (NK) cell expansion in response to low-dose IL-2, and the effectiveness of patients' peripheral blood mononuclear cells (PBMC) in a standard antibody-dependent cell-mediated cytotoxicity (ADCC) assay directed against a HER2 target cell.
II. To determine the pharmacokinetics of trastuzumab using an every 2-week schedule.
