Mechanism of action

As a SERD, HM11260C binds to the estrogen receptor with high affinity and promotes its proteasomal degradation, eliminating both ligand-dependent and ligand-independent estrogen receptor signaling. This mechanism differs from selective estrogen receptor modulators (SERMs) by achieving complete receptor elimination rather than partial antagonism, potentially overcoming resistance mechanisms in hormone receptor-positive breast cancer.
