The purpose of this clinical trial is to determine if RPR109881 is a better treatment than capecitabine (Xeloda) for advanced breast cancer in patients that no longer benefit from docetaxel and/or paclitaxel.
All patients in this trial will receive either the investigational drug or capecitabine, a chemotherapy drug that is already approved to treat your disease. These drugs prevent tumor cells from dividing, so they may stop growing or die. The investigational drug in this clinical trial is a chemotherapy drug given through the vein once every three weeks. Patients who receive capecitabine will receive this drug by mouth for 14 days, every 21 days.
