Summary

This trial will study the effects of a new cancer drug on the tumor and the patient's immune system.

Who is the study for?
This trial is for women over 18 with advanced ER+/HER2- breast cancer who can swallow pills, have good organ function, and can undergo biopsies. They should not be using hormonal birth control or have active cancers (except certain skin cancers), autoimmune diseases, serious infections, or conditions that make biopsy unsafe.
What is being tested?
The study tests how standard endocrine therapy plus abemaciclib affects immune cells in the tumor environment of breast cancer patients. It involves detailed analysis through single cell RNA sequencing and monitoring changes related to serum estrogen levels.
What are the potential side effects?
Potential side effects include reactions from biopsies, fatigue from treatment, possible digestive issues due to oral medications, and risks associated with changes in immune cell functions which could affect overall immunity.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Changes in serum estrogen (E1 and E2) levels compared to changes in tumor immune cell repertoire and function in response to endocrine therapy and CDK 4/6 inhibition
Changes in serum estrogen (E1 and E2) levels compared to peripheral blood mononuclear cell repertoire and function in response to endocrine therapy and CDK 4/6 inhibition
Secondary study objectives
Best overall response rate of abemaciclib and endocrine therapy in both treatment arms
Changes in tumor immune cell populations in response to fulvestrant and aromatase inhibitor therapy plus abemaciclib, measured by sequential biopsies
Biopsy
