A Window of Opportunity Study of Dasatinib in Operable Triple Negative Breast Cancers with Nuclear Epidermal Growth Factor Receptor
Triple negative breast cancer may be influenced by something called "Epidermal Growth Factor Receptor"(EGFR). Current research has shown that although EGFR is identified, medications blocking EGFR do not have much effect for triple negative breast cancer. Researchers think this is because EGFR may not be in the correct location in the cell (in the nucleus rather than the plasma menbrane) and that this causes resistance. Treatment with a medication targeting another component of the cell called Src may help keep EGFR in the correct place. This medication is called dasatinib. This study is being done to determine if dasatinib can keep the EGFR in the correct location. We also want to make sure treatment with dasatinib is safe and tolerable for patients with TNBC who have surgery. In the future, this may allow new combination therapies to be studied for triple negative breast cancers that are identified to have EGFR in the nucleus.
Dasatinib is an oral tyrosine kinase inhibitor.
You will start treatment with dasatinib 7-10 days before your planned surgery to remove your TNBC. Dasatinib is a pill that you would take once a day until the surgery. Tissue from your surgery will be used by the researchers to do further testing related to the study. Approximately 30 days after your surgery you will be asked to return to the clinic for one more study related clinic visit, which will also include additional laboratory tests.
