Breast Cancer Clinical Trial
[18F]FLT PET/CT in Rb+ Metastatic Breast Cancer
Summary
In this study positron emission tomography (PET/CT) imaging will be used to evaluate proliferative activity in sites of metastatic disease using the investigational radiotracer [18F]fluorothymidine (FLT).
Full Description
This protocol is designed to develop relationships between parameters determined from imaging biomarker studies and ones used for determination of therapeutic response to combined CDK4 Inhibitor and chemotherapy regimens. Imaging will occur prior to starting therapy on the separate therapeutic protocol UPCC 06115. Patients may undergo a second FLT PET/CT scan following a 3-day run of ribociclib (LEE011) (day -6 to -4) and a third FLT PET/CT scan on cycle 1 day 12 following two treatments of weekly Paclitaxel to compare changes in FLT uptake measures.
Eligibility Criteria
