Addex Therapeutics https://www.globenewswire.com/Tracker?data=R6GMQQtshEeKOIDY9rMEXlOD9fXuLZq2exFrJuTlHcfimOWwr_P86CQ6p3djGGsCXAzArRE93UOrG-tESM_WLWAXFJlV-HcEkdYrKIGayDC9yxM7mSC-7H-5SarHBu_e 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. Allosteric modulators offer several potential advantages over conventional, non-allosteric molecules and may offer an improved therapeutic approach to conventional "orthosteric" small molecule or biological drugs. Addex's allosteric modulator drug discovery platform targets receptors and other proteins that are recognized as essential for therapeutic intervention. Addex's lead drug candidate, ADX71149 (mGlu2 positive allosteric modulator or PAM), developed in collaboration with Janssen Pharmaceuticals, Inc., is in a Phase 2 clinical trial for the treatment of epilepsy. The company's second clinical program, dipraglurant (mGlu5 negative allosteric modulator or NAM), is under evaluation for future development in post-stroke recovery. Indivior PLC has licensed Addex's GABAB PAM program for the development of drug candidates, with a focus on substance use disorder. Addex is also advancing a broad preclinical pipeline, which includes development of a range of GABAB PAM for chronic cough, mGlu7 NAM for stress related disorders, M4 PAM for schizophrenia and other forms of psychosis and mGlu2 NAM for mild neurocognitive disorders and depression. Addex shares are listed on the SIX Swiss Exchange and American Depositary Shares representing its shares are listed on the NASDAQ Capital Market, and trade under the ticker symbol "ADXN" on each exchange.
