About Addex Therapeutics:
Addex Therapeutics  is a clinical-stage pharmaceutical company focused on the development and commercialization of an emerging class of novel orally available small molecule drugs known as allosteric modulators for neurological disorders.

Indivior PLC has licensed Addex’s GABABPAM program for the development of drug candidates, with a focus in substance use disorder.
