Summary
Triple negative breast cancer (TNBC) has an aggressive phenotype and poor prognosis. This tumor type characterized by lack of expression of estrogen receptor (ER), progesterone receptor (PR) and no amplification of the human epidermal growth factor 2 (HER2) accounts for 15% of breast cancers. Limited treatment options exist in the clinic as hormonal therapies and HER2-trageted agents have proven ineffective. BKM120 is a drug that works by blocking a protein called phosphatidylinositol-3-kinase (PI3K) which may contribute to cancer growth. This drug has been used in experiments in the laboratory and information from these research studies suggests that BKM120 may help to prevent cancer cells from growing. In this research study, the investigators are looking to see if BKM120 works to stop breast cancer cells from growing.
