What This Trial Is Studying

This trial will study a type of advanced breast cancer (ABC) defined as endocrine receptor (ER)-positive/human epidermal growth factor receptor 2(HER2)-negative and estrogen receptor 1 (ESR1)-mutated. Patients will be treated with elacestrant, a compound that acts as a selective estrogen receptor degrader, and everolimus (or placebo), a kinase inhibitor indicated for the treatment of postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer. The main purpose of the study is to analyze the efficacy (to find out how effective a treatment is) of elacestrant plus everolimus therapy in patients who…
