New drug combination delayed disease progression for subgroup of women with metastatic breast cancer

Adding the drug dasatinib to a standard antihormone therapy, letrozole, doubled the time before disease progressed for women with hormone receptor-positive, HER2-negative metastatic breast cancer, according to results of a phase II clinical trial presented at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.Dasatinib is approved by the U.S. Food and Drug Administration for the treatment of chronic myelogenous leukemia. One of the ways it works is by blocking the activity of a protein called Src, which has been recently implicated in the spread of breast cancer to bones.
