The main purpose of this research study is to see if the study drug, named CP-724,714, can help in the treatment of certain breast cancers that have spread to other locations in the body. Other goals of this study are to measure how long it may take for the cancer to get worse (progress), to see if there are any side effects from the study drug, to check the amount of study drug in the blood at different times, and to check to see if there is any relationship between certain blood tests and how patients may respond to the study drug.
