Summary
Brief summary (as posted)
The purpose of this study is to see if the investigators can measure inhibition of a protein, Src (named for Sarcoma), in tissue and blood in patients with a diagnosis of endometrial cancer. Dasatinib is a drug that blocks the activity of an important protein in cancer cells called Src. The investigators can measure the blocking of Src in the bloodstream. However, the investigators do not know if measures in the bloodstream reflect blockage of Src in cancer tissue. The investigators are doing this study to try and see if the investigators can match what the investigators see in cancer tissue to what the investigators see in the bloodstream. the investigators hope that in the future, the investigators can use blood to measure protein inhibition by dasatinib instead of asking patients to undergo repeat biopsies.

[]Primary outcomes (1)
- measure
- Changes in levels of SFK protein activity in a) endometrial tumor tissue and b) blood induced within two different doses of dasatinib treatment.
- timeFrame
- 1 year
- description
- In this study the change in levels of SFK protein activity in both tissue and blood will represent the measured pharmacodynamic response.
Secondary outcomes (1)
- measure
- Changes in levels of SFK protein activity in blood correlates with changes in levels of SFK protein activity in endometrial tumor tissue induced by two different doses of dasatinib treatment.
