Mavoglurant (AFQ056) is an experimental drug candidate for the treatment of fragile X syndrome.[1] It exerts its effect as an antagonist of the metabotropic glutamate receptor 5 (mGLU5).[2]

Mavoglurant is under development by Novartis and is currently in Phase II and Phase III clinical trials.[1][3] Phase IIb/III dose finding and evaluation trials for fragile X-syndrome have been discontinued by the end of 2014. [4] Otherwise, it would have been the first drug to treat the underlying disorder instead of the symptoms of fragile X syndrome.[5]
Mavoglurant is also in Phase II clinical trials for Levodopa-induced dyskinesia.[6][7]
In 2007, Norvartis had conducted a clinical study to assess its ability of reducing cigarette smoking, but no results had been published up till now.[8]
Currently Novartis is conducting a clinical trial with this drug on obsessive compulsive disorder.[9]

Novartis discontinued development of mavoglurant for fragile X syndrome in April 2014 following disappointing trial results.[10]
