Elacestrant (ORSERDU™) is an orally available selective estrogen receptor degrader (SERD) being developed by Stemline Therapeutics, a subsidiary of Menarini Group, for the treatment of estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. In January 2023, elacestrant received its first approval for the treatment of postmenopausal women or adult men with ER-positive, HER2-negative, estrogen receptor 1 (ESR1)-mutated (as determined by a US FDA-approved test) advanced or metastatic breast cancer with disease progression following ≥ 1 line of endocrine therapy in the USA. A regulatory assessment of elacestrant for the treatment of ER-positive, HER2-negative advanced or metastatic breast cancer is currently underway in the EU. Development of elacestrant for the treatment of vasomotor symptoms has been discontinued. This article summarizes the milestones in the development of elacestrant leading to this first approval for this indication.
