About this study

This phase II trial tests how well tamoxifen and pegylated liposomal doxorubicin works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or that has spread to nearby tissue or lymph nodes (locally advanced) and is unable to be operated on (inoperable). Tamoxifen works by blocking the effects of estrogen in the breast. This may help stop the growth of tumor cells that need estrogen to grow. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Liposomal doxorubicin is a form of the anticancer drug doxorubicin that is contained inside very tiny, fat-like particles. Liposomal doxorubicin may have fewer side effects and work better than other forms of the drug. Giving tamoxifen and pegylated liposomal doxorubicin together may work better in treating patients with metastatic or inoperable, locally advanced triple negative breast cancer than giving either of these drugs alone.
