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). [5] [6] [7]
