Bexirestrant is a selective estrogen receptor degrader (SERD) which is being evaluated for the treatment of breast cancer. This orally bioavailable compound has demonstrated potent activity against both wild-type and mutant forms of the estrogen receptor (ER), addressing a critical need in overcoming resistance to current endocrine therapies.

It is structurally characterized by an E-alkene linked to an azetidine core.
