Afegostat (INN; also known as isofagomine; planned trade name Plicera) was an experimental drug for the treatment of certain forms of Gaucher's disease that was being developed by Amicus Therapeutics and Shire plc until a failed clinical trial in 2009 led to termination of its development. The substance was used in form of the tartrate.
Mechanism of action
[edit]Invention and development
[edit]Afegostat was invented by Mikael Bols and Troels Skrydstrup and was first prepared by Jespersen and Bols.[3]
Amicus Therapeutics licensed patents related to afegostat from Mt. Sinai School of Medicine, University of Maryland, and Novo Nordisk A/S. They also signed a collaboration agreement with Shire plc related to this drug and others.[4]: 13
It was granted orphan drug status by the European Medicines Agency (EMA)[5] and by the US FDA.[4]: 10
When afegostat failed a Phase II clinical trial in 2009, Shire terminated the collaboration agreement and Amicus determined it would no longer develop the afegostat.[4]: 2, 10, 11 The first patents in Amicus' patent portfolio on afegostat expired in 2015.[4]: 12
