From Wikipedia, the free encyclopedia
A selective estrogen receptor degrader or downregulator (SERD ) is a type of
drug which binds to the
estrogen receptor (ER) and, in the process of doing so, causes the ER to be degraded and thus
downregulated .
[1] They are used to treat estrogen receptor-sensitive or progesterone receptor-sensitive
breast cancer , along with older classes of drugs like
selective estrogen receptor modulators (SERMs) and
aromatase inhibitors .
[1]
As of 2016 the only marketed SERD was
fulvestrant (brand name
Faslodex ).
[1] As of November 2016 other SERDs under development include
brilanestrant and
elacestrant .
[2] The clinical success of
fulvestrant led to efforts to discover and develop a parallel drug class of
selective androgen receptor degraders (SARDs).
[2]
Investigational
Fulvestrant requires large-volume and frequently painful intramuscular injections.
[3] In response, pharmaceutical companies are currently developing oral SERDs. Among products in development are:
[4]
The oral SERDs target ER-positive/HER2-negative
breast cancer and are tested as monotherapy and in
combination with other drugs such as the
CDK inhibitor
palbociclib (Ibrance).
