Addex: Van Leeuwenhoeck Issues Update Equity Research Report

Geneva, Switzerland, December 3, 2019 Addex Therapeutics (SIX: ADXN), a clinical-stage leading allosteric modulation-based drug discovery and development company, today announced the independent life science equity research company, Van Leeuwenhoeck, has issued an updated equity research report highlighting the Addex investment opportunity. In their report they highlight the expected start in Q1 2020 of a pivotal registration phase 2b/3 clinical trial with dipraglurant for the treatment of levodopa-induced dyskinesia associated with Parkinson’s disease (PD-LID), a $4 billion market opportunity in the United States.

“We believe Addex is fundamentally undervalued and the start of a pivotal registration study in PD-LID is likely to drive significant share price appreciation in the coming 12 months,” commented Marcel Wijma, Chief Research Analyst at Van Leeuwenhoeck Institute. “Furthermore, Addex has a world leading position in allosteric modulation, a deep neuroscience pipeline and partnerships with Industry which we expect to drive further value creation and newsflow.”

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. 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, dipraglurant (mGlu5 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 registration trials for PD-LID. In parallel, dipraglurant's therapeutic use in dystonia is being investigated in preclinical models. Addex's second clinical program, ADX71149 (mGlu2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc for the treatment of epilepsy. In addition, Addex’s GABAB PAM program has been licensed to Indivior PLC for the treatment of addiction. Preclinical programs include GABAB PAM for CMT1A, mGlu7 NAM for PTSD, mGlu2 NAM for mild neurocognitive disorders, mGlu4 PAM for Parkinson’s disease and mGlu3 PAM for neurodegenerative disorders.
