4 INTERACT- Integrated Evaluation of Resistance and Actionability Using Circulating Tumor DNA in HR Positive Metastatic Breast Cancers

This phase II trial studies how well letrozole, anastrozole, or fulvestrant work when given together with ribociclib, palbociclib, and/or abemaciclib in treating patients with hormone receptor (HR) positive breast cancer that has spread to other places in the body (metastatic) and has an ERS1 activating mutation. Letrozole, anastrozole, ribociclib, palbociclib, and abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by blocking the use of estrogen by the tumor cells. It is not yet known if giving letrozole, anastrozole, or fulvestrant with ribociclib, palbociclib, and/or abemaciclib will work better in treating patients with breast cancer.
