Addex Therapeutics is a biopharmaceutical company focused on the development of novel, orally available, small molecule allosteric modulators for central nervous system disorders.

Addex lead drug candidate, dipraglurant (mGluR5 negative allosteric modulator or NAM) has successfully completed a Phase 2A POC in Parkinson’s disease levodopa-induced dyskinesia (PD-LID), and is being prepared to enter Phase 2B for PD-LID. In parallel, dipraglurant’s therapeutic use in dystonia and treatment resistant depression is being investigated. Addex second clinical program, ADX71149 (mGluR2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc. Addex also has several preclinical programs including: ADX71441 (GABAB receptor PAM) which has received regulatory approval to start Phase 1 and is being investigated for therapeutic use in Charcot-Marie-Tooth (type 1A) disease, alcohol use disorder and nicotine dependence; mGluR4 PAM for drug abuse and dependence, Parkinson’s disease and other neurodegenerative diseases; mGluR2 NAM for treatment resistant depression and cognitive deficits; mGluR7 NAM for psychosomatic disorders, TrkB PAM for neurodegenerative disorders; and GLP1 PAM for type 2 diabetes.

Allosteric modulators are an emerging class of small molecule drugs which have the potential to be more specific and confer significant therapeutic advantages over conventional "orthosteric" small molecule or biological drugs. Addex allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention – the Addex pipeline was generated from this pioneering allosteric modulator drug discovery platform.

Founded in 2002, Addex is headquartered in Geneva and listed on the SIX Swiss Stock Exchange under the trading symbol ADXN.
