NCIt definition : An orally available, selective estrogen receptor degrader (SERD), with antineoplastic
activity. Upon oral administration, elacestrant acts as a SERD, which binds to the
estrogen receptor (ER) and induces a conformational change that results in the proteosomal
degradation of the receptor. This prevents ER-mediated signaling and inhibits proliferation
of ER-expressing cancer cells.;
