TAS-108 (also known as SR-16234) is a selective estrogen receptor modulator (SERM) and has been reported to have estrogen receptor (ER) α antagonistic activity and a strong affinity with a weak partial agonistic activity to ERβ receptor. It is known that ERs play a central role in the diverse actions of estrogen. TAS-108 was studied in phase II clinical trials to treat recurrent or recurrent inoperable breast cancer. In addition, TAS-108 participated in Japan in a phase II clinical trial in Endometriosis patients. The phase III studies are being planned with the drug.
