Brief Summary:
This phase II trial tests the accuracy of functional imaging (FFNP)-positron emission tomography (PET)/computed tomography (CT) to predict response to abemaciclib plus endocrine therapy. Abemaciclib is a drug used to treat certain types of hormone receptor positive (HR+), HER2 negative breast cancer. Abemaciclib blocks certain proteins, which may help keep tumor cells from growing. Endocrine therapy adds, blocks, or removes hormones that can cause cancer to grow. FFNP PET imaging is a form of x-ray that uses FFNP as an imaging agent that may provide more precise information about the location of tumors that "light up" with FFNP than a PET scan alone can provide.
Detailed Description:
OUTLINE:
Patients receive FFNP intravenously (IV) and undergo PET/CT imaging at baseline. Patients then receive estradiol orally every 8 hours (Q8H) over a 24-hour period, followed again by FFNP IV and PET/CT imaging. Patients then receive abemaciclib orally (PO) twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive endocrine therapy (ET) of the treating physician choice. Patients also receive FDG IV and undergo PET/CT imaging at baseline, with additional diagnostic imaging for tumor assessment every 3 cycles, and undergo blood sample collection throughout the study.
After study completion of study, patients are followed every 3 months.
