Outcome Measures
Primary Outcomes (1)
Measure changes in [18F]FLT uptake in metastatic tumors before and during treatment with ribociclib (LEE011) only, patient will have FLT PET/CT scan at baseline, run-in day -3, and cycle 1, day 1 of ribociclib (LEE011)/paclitaxel therapy
Measure changes in \[18F\]FLT uptake in metastatic tumors before and during treatment with ribociclib (LEE011) only and associate these changes with response to ribociclib (LEE011)/paclitaxel therapy.
4 years
Secondary Outcomes (1)
Measure changes in [18F]FLT uptake in metastatic tumors during and after treatment with ribociclib (LEE011) only, patient will have FLT PET/CT scan at baseline, run-in day -3, and cycle 1, day 1 of ribociclib (LEE011)/paclitaxel therapy

Interventions
Eligibility Criteria
You may qualify if:
- At least 18 years of age
- History of histologically or cytologically confirmed breast cancer, any ER, PR or HER2 status is allowed as long as it expresses the Rb protein.
- At least one site of metastatic breast cancer that is outside of the liver and bone that is identified by standard imaging (e.g. CT, MRI, FDG PET/CT, ultrasound, x-ray)
- Participants must be informed of the investigational nature of this study and provide written informed consent in accordance with institutional and federal guidelines prior to study-specific procedures.
- Patients must be candidates to receive treatment on the therapeutic trial UPCC06115, a Phase I study of ribociclib (LEE011) and weekly paclitaxel.
You may not qualify if:
- Females who are pregnant at the time of screening will not be eligible for this study, urine pregnancy test will be performed at screening in women of child-bearing potential.
- Inability to tolerate imaging procedures in the opinion of an investigator or treating physician
- Serious or unstable medical or psychological conditions that, in the opinion of the investigator, would compromise the subject's safety or successful participation in the study.
- Ineligible for the therapeutic trial UPCC 06115
