Phase: Phase 2
Diagnosis: Breast: Metastatic
NCT ID: NCT01738438 (View complete trial on
DFCI Protocol ID: 12-431


This research study is Phase II clinical trial, which tests the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is being studied. It also means that the FDA has not yet approved XL184 for use in patients, including people with your type of cancer. XL184 is a drug that may stop cancer cells from growing. It is a small molecule kinase inhibitor that inhibitors met and VEGFR2, as well as other targets. This drug has been used in Phase I studies in humans and laboratory experiments, and information from those other research studies suggests that this drug may help to slow tumor progression in this research study. This drug has also been used in a phase II study for breast cancer patients (a randomized discontinuation trial) suggesting good benefit for this group of patients. In this research study, we are looking at the anti-tumor effects of XL184 in metastatic breast cancer.
