Elacestrant (INN ) (developmental code names RAD-1901 , ER-306323 ) is a nonsteroidal combined selective estrogen receptor modulator (SERM) and selective estrogen receptor degrader (SERD) (described as a "SERM/SERD hybrid (SSH)") that was discovered by Eisai and is under development by Radius Health and Takeda for the treatment estrogen receptor (ER)-positive advanced breast cancer .[ 1] Elacestrant has dose-dependent, tissue-selective estrogenic and antiestrogenic activities, with biphasic weak partial agonist activity at the ER at low doses and antagonist activity at higher doses.[ 2] It shows agonistic activity on bone and antagonistic activity on breast and uterine tissues.[ 3] Unlike the SERD fulvestrant, elacestrant is able to readily cross the blood-brain-barrier into the central nervous system , where it can target breast cancer metastases in the brain ,[ 2] [ 3] and is orally bioavailable and does not require intramuscular injection .[ 2] [ 3] Menarini Group and Radius Health Announce Global License Agreement[ 4] for the Development and Commercialization of Elacestrant.
Clinical Development
As of December 2019, it is in phase III trials for breast cancer.[ 1] However, in December 2019 Radius Health announced plans to divest of oncology assets (including elacestrant). [ 5]
Sep 24, 2020, Radius Health & Menarini Group Provide Elacestrant Update.[ 6] October 20, 2021, Menarini Group and Radius Health[ 7] announce positive phase 3 topline results[ 8] from the EMERALD trial evaluating elacestrant in breast cancer.
