Mechanism of action

HGP0904 functions as a SERD by binding to the estrogen receptor with high affinity and promoting its proteasomal degradation, thereby 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 modulation. The drug is designed to overcome resistance mechanisms that develop with standard endocrine therapies in estrogen receptor-positive breast cancer.
