- Drug Entry
- Lasofoxifene
Lasofoxifene is a non-steroidal 3rd generation selective estrogen receptor modulator (SERM) that selectively binds to both ERα and ERβ with high affinity. It is a naphthalene derivative marketed for prevention and treatment of osteoporosis and for the treatment of vaginal atrophy. It was initially developed as Oporia by Pfizer as a treatment for postmenopausal osteoporosis and vaginal atrophy, in which were both rejected for approval by FDA. Later Fablyn was developed as a result of a research collaboration between Pfizer and Ligand Pharmaceuticals with a newly submitted New Drug Application in 2008. It gained approval by European Commission in March 2009. Ligand Pharmaceuticals signed a license agreement with Sermonix Pharmaceuticals for the development and commercialization of oral lasofoxifene in the USA.
