How does this medicine work?[edit | edit source]

  • An orally available, selective estrogen receptor degrader (SERD) and selective estrogen receptor modulator (SERM), with potential antineoplastic and estrogen-like activities.
  • Upon oral administration of higher doses of elacestrant, this agent acts as a SERD, which binds to the estrogen receptor (ER) and induces a conformational change that results in the degradation of the receptor.
  • This may inhibit the growth and survival of ER-expressing cancer cells.
  • At lower doses of this agent, RAD1901 acts as a SERM and has estrogen-like effects in certain tissues, which can both reduce hot flashes and protect against bone loss.
