What is Fulvestrant?

Fulvestrant (Faslodex, AstraZeneca) is a drug treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following anti-estrogen therapy. It is a complete estrogen receptor antagonist with no agonist effects, which in addition, accelerates the proteasomal degradation of the estrogen receptor.

Fulvestrant provided effective second-line therapy in this setting for postmenopausal women who had relapsed or progressed after previous endocrine therapy.

In particular 4 clinical trials in this setting did show similar efficacy to the other hormonal agents (aromatase inhibitors and tamoxifen) with good tolerability profile. Fulvestrant had a lower incidence of joint disorders.

The original patent for Faslodex expired in October 2004. Drugs subject to pre-marketing regulatory review are eligible for patent extension, and for this reason AstraZeneca got an extension of the patent to December 2011.

AstraZeneca has filed later patents. There is no generic Faslodex available. A later patent for Faslodex expires in January 2021.
