After the MTD is established for each combination (Phase 2), subjects will be enrolled to evaluate the preliminary efficacy and safety of these combinations in subjects with breast cancer refractory to a non-steroidal aromatase inhibitor that is ER+/PGR+ and HER2-. Letrozole is used in the treatment of different types of breast cancer, but patients can develop resistance.\n\nUpregulation of PI3K activity is one of the most common characteristics of human cancer cells, including breast tumor cells. Activation of PI3K results in stimulation of AKT and mTOR kinases, resulting in the promotion of tumor cell proliferation and survival. Preclinical and retrospective clinical data suggest that aberrant activation of the PI3K pathway may play a role in aromatase inhibitor resistance in patients with ER+, HER2- breast cancer. XL147 is a potent inhibitor of PI3K, and XL765 is a potent dual inhibitor of PI3K and mTOR; therefore either of these compounds in combination with letrozole warrants clinical investigation.'},
