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]
- Giredestrant: Roche
- Amcenestrant (SAR439859): Sanofi
- Camizestrant (AZD9833): AstraZeneca
- Rintodestrant ( G1T48 ) : G1 Therapeutics
- LSZ102: Novartis
- Imlunestrant (LY3484356): Eli Lilly
- Elacestrant: Radius Health
- ZN-c5: Zentalis
- Taragarestrant (D-0502): Inventisbio
- SHR9549: Jiangsu Hengrui Medicine
- Vepdegestrant ( ARV-471 ): Oral estrogen receptor PROTAC protein degrader for breast cancer by Arvinas Pharmaceuticals.
- ZB716 ( Fulvestrant boronic acid ).
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]
