Description: Basimglurant, also known as RO 4917523 and RG-7090, is a novel mGlu5 negative allosteric modulator currently in Phase 2 clinical development for MDD and Fragile X syndrome (FXS). Basimglurant is a promising novel medicine for psychiatric diseases. Basimglurant has favorable drug-like properties, a differentiated molecular mechanism of action, and antidepressant-like features which suggest the possibility of also addressing important comorbidities of MDD including anxiety and pain as well as daytime sleepiness and apathy or lethargy.
