Fulvestrant is a drug treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression as well as HR-positive, HER2-negative advanced breast cancer in combination with palbociclib in women with disease progression after endocrine therapy.

It is a selective estrogen receptor degrader (SERD) and was first in class to be approved. It works by binding to the estrogen receptor and destabilizing it, causing the cell’s normal protein degradation processes to destroy it. It is given by muscle injection.
